A hydraulic press with your own hands from a jack

Homemade jack press with his own hands

I decided to make a homemade press from a jack. Materials I already had in the garage, I did with what was.

The Soviet jack for 5 tons, channel 160. 2,5 meters, corner 90. 2,5 meters. I had to buy only electrodes 3, disks on an angle grinder. 3 pcs, a pair of springs and paint. paint.

By profession I am a design engineer, so I decided to make drawings and calculate the metal that was available.

Execution of work

The most popular and versatile option. the hydraulic press. First of all a platform is created to accommodate the jack and the frame. The foundation should be the most reinforced part of the press, since it takes the heaviest load, which then distributes to the rest of the structure.

Platform and frame are made of channel bars and additionally reinforced with stiffening ribs. All seams must be welded on both sides. For more jack resistance a rectangular sheet of metal is welded to the jack. To move the movable stop element without distortions the guiding flags are welded to the frame. You must first make drawings of the hydraulic hand press. With their own hands to draw them is not difficult, besides so you take into account all the details of the future device.

Support and struts

The next step is to make the stop and supports. A channel or an angle bar is used. The length of the stop should match the width of the support mechanism. All joints are properly welded. After that you should make a removable stop, it will move along the rails and transmit the force from the jack. For this, two strips of sheet metal are cut and holes are drilled for bolts.

Small hooks are welded to fix the springs. At the lower location of the jack, relative to the entire structure, you can be limited to weak springs or abandon them altogether. In this case, the weight of the whole construction will press on the jack and thus push the rod. Springs will also not be needed with a screw jack.

For a overhead press, very strong springs must be used. They, in addition to overcoming the resistance of the hydraulic fluid in the jack, will need to pull up the weight of the jack and the stop.

If you plan to use the press for auto repair work, it will be convenient to make a thrust rod from a pipe or a broken shaft. It is needed to press out and press in parts.

Assembling elements

The next stage of the work is the assembly and adjustment of all the elements of the press. And also check all the welds. Welding must be flawless, any defect when working under load can cause the press to collapse and even risk an accident. The final touch is to prime and paint the entire structure. The press is ready and it is designed so that the jack can be taken out easily if needed.

Such an uncomplicated way to acquire a very useful tool in the economy: a press for making parts or press for apples, your own hands can make the type of equipment that will be needed.

When performing various works in the home workshop, it is often necessary to influence the processed parts by pressing. About how to make a hydraulic press with your own hands to perform such operations, and we will talk in this article.

Hydraulic press with their own hands

Homemade hydraulic press with his own hands from a jack: photo of the step-by-step making a homemade with a description.

I periodically have to change the silent blocks and bearings in a vise, so I thought about how to make a hydraulic press myself.

Used the following materials:

hydraulic, press, your, hands, jack
  • Jack.
  • Angle 50. 4 pcs x 0.5 m.
  • Car shock absorber.
  • Channel 8. 6 pcs x 0.5 m.
  • Stud 8. 2 pcs x 1.5 m.
  • 8 channel. 4 pcs x 8 cm.
  • Bolt 12 x 120. 12 pcs.
  • Bolt 10 x 40. 8 pcs.
  • Bolts 8×30. 20 pcs,
  • Sheet metal thickness of 10 mm, size 160 mm x 160 mm. 2 pcs.
  • Springs. 4 pcs.

Well, actually and photo of the whole process of assembling a manual press from a jack.

To the metal plate welded a piece of pipe at 30, it will be inserted rod jack, plate mount bolts at 8.

The plate with the rod from the shock absorber, will be attached to the movable part of the press, which will be suspended on springs.

Purpose and applications of the hydraulic press

A hydraulic press is a device that exerts great pressure on the material to be worked by means of slight forces. This operating principle is based on Pascal’s law, which states that the applied force acting on a given area is transmitted throughout the entire volume and is equal in all directions.

Hydraulic press is used for stamping, pressing, squeezing, assembling, forging and bending.

The design of a hydraulic press is represented by two cylinders. When acting on the smaller chamber, the fluid pressure in it increases, which is transmitted through a special channel to the large chamber. The working fluid is pressed on the piston, which causes the element to act on the work piece. The cylinders are generally arranged vertically, but there are also horizontally placed versions. Special oil is used as a working fluid.

The unit is used for pressing, stamping, extruding, assembling, forging, bending and straightening of metal elements. You can buy or make your own hands a cardboard press, which will be indispensable for baling, briquetting, pressing and recycling of materials made of plastics, paper and rubber. The equipment is versatile and can be used in many areas of life for repair, maintenance and preventive maintenance. Depending on this, the press has a specific design.

Press construction: features of existing devices

To create a significant force on a certain area is used design of the hydraulic press, buy such a unit can be specialized stores. This machine is an effective and simple device.

If you decide to make such a construction according to the drawings, it is necessary to understand what it consists of:

  • the lower part or the base is necessary for stability. It looks like a platform and is made of solid metal. Metal corners and channels are suitable for this purpose;
  • The uprights are the vertical parts of the structure. The height of the elements is calculated as the sum of the length of its rod, the height of the jack and the thickness of the fixed stop. The props are made of steel angles welded to the base;
  • the fixed stop is fixed in the upper part of the columns. To make it used the same angle, as the racks;
  • the jack allows to develop the necessary force. This element is fixed to the movable support. It is driven electrically or manually;
  • The movable stop exerts the main pressure on the mechanism. Can be made of corners or strips of steel;
  • the return device is used to move the sliding stop to the normal position. It uses springs, the degree and length of stretching, which is calculated depending on the parameters of the press.

Vacuum press

When making a vacuum press with your own hands, you should consider that the device consists of a thermomodule, a table and a vacuum chamber. The last element is often rectangular in shape and made of rigid material.

This design has some features:

hydraulic, press, your, hands, jack
  • The machine has only manual operation;
  • Available materials are used for the work;
  • the speed of operation should not be inferior to the factory analogues.

The vacuum construction is assembled from the following parts:

  • The bed is made of a rail for the thermomodule and a profiled tube. For work you will need a welder and an electric drill;
  • Vacuum table is made of a pressing frame, clamps and tub;
  • A water ring pump is also needed.

Thermo-vacuum press is made similarly.


Such machine as a baler is installed as a trailed mechanism for power tillers. It is used on small farmers’ fields and on large farms. After the herbage is cut with the mower, the machine processes it. The machine forms rolls the stalks into rolls and then uses the machine to form bales.

These are the benefits of using this machine:

  • It reduces the drying time and loss of hay;
  • Several times the labor costs are reduced;
  • It improves the quality of the hay during storage;
  • You can adjust the baler yourself.

The following diagram shows a variant of the roll forming machine

The most common variant is the roll mechanism. Spring tines allow for the collection of grass masses. Each batch is then rolled into bales. A mini-tractor with such a press can load up to 20 tons of straw in 20 days. The bales are small in size.

The baler of the baler variety makes bales in the shape of a rectangle. The grass in the windrows is picked up by the tines and sent to the baling chamber. Dimensions can be adjusted by the technique. The bales are securely packed and tied with twine. After that the block is thrown on the field.

It is also possible to make a homemade version from walking beam and lumber. This makes a large box of boards and uses a horizontal method for loading the hay. A slatted or screw jack is used as a press. It can bale straw and compress it.

Tabletop mechanical press

The table press can operate both on automatic and manual traction. Such equipment is often made of strong steel.

Hand presses are machined with the help of a hand press:

The mechanical press is used to press out bearings and bushings, punch and die small items. Such a machine saves time in making parts.

The hydraulic hand-operated unit uses a hydraulic cylinder rod to exert force. The unit contains fluid that is compressed under pressure. The machine is used for compressing, deforming and joining parts.

The punching version is used for punching holes in sheets of different materials. Manual mechanical presses are needed for pressing tubular sleeves and cables.


Vibropress allows you to reduce the time of construction works, as well as reduce their cost. The machine design implies three drives: hydraulic, mechanical and pneumatic. The unit is based on the vibro press technology.

Even with a manual and the necessary drawings, the creation of a vibropress with their own hands may not work out. This can happen due to incorrect calculations, inaccurate adjustment and low performance.

Press with an electric drive

Hydraulic press with an electric drive has a simple device. Most often it consists of a thick angle and a channel. All elements are connected by thick bolts.

Features of creating a hydraulic press with your own hands

Homemade construction must perform the necessary list of tasks. The device, which creates a force of 15-25 tons, is enough. For its manufacture will need to prepare a working drawing of the hydraulic press with their own hands from the jack with the dimensions of all the elements of the design (such a scheme can be found on the Internet). It should take into account the type of tool, which can be stationary or removable, the dimensions of the product, the stroke of the piston and the design of the bed.

hydraulic, press, your, hands, jack

Depending on the type of installation, the hydraulic press can be table or floor standing

The operating cylinder of the hydraulic press is either separately located or integrated into the structure. It may be at the top or at the bottom. In the case of the first option, the pressure will be exerted on the lower surface of the base. If the operating element is at the bottom of the frame, pressure is directed upward as a result of the main piston rod.

A jack is used as a hydraulic cylinder, which acts as the main working element. It should be taken into account that the tool can be presented in different versions. Therefore, when choosing a jack, it is necessary to determine for what purposes the press will be used and take into account the maximum force of the device.

However, it should be remembered that an industrial tool of the bottle type will not function in an upside down state. Therefore, before making a press from a jack, it is necessary to finish the product. It is necessary to provide a socket in the construction that will be in contact with the hydraulic cylinder rod. A piece of pipe should be used for its manufacture.

The material for the frame is chosen with a margin of safety to prevent damage to the frame while exerting the maximum possible force. After completing the assigned task of processing the workpiece, the rod must return to its original position. To do this, the springs must be properly selected, based on their degree of stiffness, so that they can perform their purpose effectively. Their edges are fixed to the movable upper part and the fixed lower part of the base.

The material for the columns and the frame must be chosen with sufficient strength to prevent damage to the press when great pressure is applied

What is the basic construction of the press and its various types

Many may say that there is no point in wasting time on the design and assembly and it is much easier to buy a hydraulic press or its mechanical version, but this is fundamentally wrong. Of course, if it will be used, for example, in the car service center, etc.п., perhaps the unit and will pay for itself after some time. But for home use and one-time work, the purchase will be a very irrational expenditure of money.

Baler for power tillers. very useful for dry grass

To fully understand how it works, let’s look at the design features of some of these types of machines. And start with the possibility of making your own hands vacuum press.

The main thing worth saying about this device. it is almost no use in everyday life. The fact that the thermal vacuum press is used most often for manufacturing doors and window frames, as well as various furniture fronts. It is with his help details are covered with a film (NDF). In fact, it is a large machine for laminating.

Schematic diagram of the vacuum press. very difficult to make with their own hands

Please note! Such a press is very difficult to produce. Some craftsmen say that the selfmanufacturing of such a device took them more money than would have been spent on the purchase. It is because of the great complexity and small area of application, we will not dwell on this baler in detail. It will be much more interesting to consider a baler, capable of compacting and collecting hay or straw into bales.

Design features of the hay baler

Such an elementary unit is assembled from planks and is very useful in the household.к. Compressed straw takes much less space during storage, and neat “briquettes” will be convenient to store.

Such mechanical press is a wooden box, 80 X 80 cm and 3 m long. At one end there is a hatch with a lock, and on the other. a wooden platform with a long lever, through which the hay is pressed. To understand more fully the principle of operation and structure of such a unit, you can watch a short video below.

Schematic illustration of a baling press for a hay baler

After seeing this preview, it is probably clear that this kind of press does not even require any preliminary drawings. No major differences between the two models as far as a power till press is concerned, the only difference is that the second version has no lever. Pressing is done by the same pressing platform, but with a cable drive.е. the second version is just a more mechanized version of the first one.

The miniature factory-made hydraulic press

A compact press for everyday small jobs

For home use is very well proven desktop hand press. Of course, it is possible to make it in the hydraulic version, but we will consider more complex units later. So, now let’s try to understand what exactly the principle of the mechanical table press.

Such installation is a frame welded from section iron and reinforced with ribs. Usually a manual jack is mounted on the top, so that when you turn the crank, it expands towards the bottom platform. The unit itself is bolted to the workbench.

Miniature mechanical press. it does not create a lot of force

Thus it turns out that, having placed a part in the bottom part of the steel frame, for example, by placing a tube under it, it is possible by turning the jack handle to squeeze out the middle part.This is how you squeeze or press into place the car silent blocks or bearings, etc. similar parts in their seats. The main thing is to make sure that there is no twisting under pressure.

It is possible to make a similar table or floor press, if necessary of larger size. But do not forget that in this case you need a more powerful jack, or the installation of a reducer to increase the pressure.

Sealing press or how to assemble a roller based device

Sometimes it is necessary to roll out a wire or make some plate thinner. This is where a roller press comes in handy. The principle of its operation is easy to understand for those who remember the old washing machines with a manual wringer. Superfluous moisture is removed from the laundry in them by passing the thing between two rollers. The rotation of the crank makes them rotate in opposite directions.

Roll press with their own hands. the drive from the electric motor, and manual

This is exactly how a mechanical roll press works, the only difference being the distance between the rolls can be adjusted, as well as the presence of a gear that reduces the speed of rotation, increasing power. after all, metal is much more rigid than fabric. Similar mechanisms can be made with both manual, mechanical drive, and with the electric. In this case, instead of a handle through the chain gear is necessary to connect asynchronous motor. The gearbox for this type of connection is slightly different. And it’s better to connect the motor through a frequency converter. This ensures a smoother start-up, saves energy and ensures the longevity of the motor.

A vibrating table in a cross-section. that’s what you need to make it

Making high-strength concrete products. what do you need for that?

One might ask. what does concrete have to do with presses? It turns out the connection is direct. It is for the hardening of products such as cinder block, etc.п. Vibropress is used. A mix of cement, sand, etc. is poured inside the mold of this type.д., and then it is pressed with the press and the vibration is switched on. As a result, the excess air is removed and the product acquires the necessary strength.

The jack press: the critical links

When the press is running, vibrations often give out a creaking, groaning metal. Mechanical stresses in the elements of its design are inaudible and invisible, but can quickly negate the efforts and costs of its creator, and the thwarted traverse cause injury and damage. Therefore, the choice of construction materials for the press and its technical design of the whole structure should be taken no less seriously.

The wrong solution would be a welded frame made of profiled tubing (pos. 1 in fig. The frame of a homemade press is characterized by the following features: it practically does not absorb vibration, the welded seams are subject to cracking due to the forces occurring during pressing. A trapezoidal tube is massive and very elastic, so it is a good accumulator of energy. Т.е., If one of the seams crawls a crack, a heavy, sharp-edged crosshead can instantly break and fly aside.

Examples of incorrect and correct technical design of a homemade press frame

The frame of the homemade press should be made of channels, single or double. I-beam fits worse: at the slightest asymmetry of the pressing force relative to the vertical axis of the frame in the I-beam flange there are significant transverse stresses that this type of profile is contraindicated. In addition, the I-beam is not designed to accept concentrated loads.

A frame welded from a single channel with reinforcing brackets (pos. 2 in fig.The frame will be sufficiently strong and stable under the load of approx. up to 5 tons; a 10-ton jack is too strong for this press. Press traverses for clamping force up to 12-15 ton-force should be made of paired channel flanges outward, pos. 3. This is again the best option for a garage or garage: there is no need to do in the beams holes for the passage of shafts, impermissibly weakening the frame. If the press is designed to work under maximum loads (stamping, forming, bending), the best solution is a heavy single channel (see drawings and tables). below) and the frame bolted together pos. 4; tack welding in this case is technological, facilitating frame assembly. The bolts, first, will eliminate the sudden collapse of the frame. Secondly, they are good vibration absorbers.

What to take an I-beam?

dimensions of channel bars for hydraulic press frame made of a jack are chosen as follows. (assuming that the profile is made of normal structural steel St44 or similar, and the beams solid):

  • For a force of up to 2 ton-force. single from 80x40x4 mm; coupled from 60x30x4 mm.
  • For a force of 2-5 ton-force. single, from 100x50x6 mm; coupled, from 80x40x4 mm.
  • For the force of 5-10 tf. single from 160x80x8 mm; coupled from 120x60x6 mm.
  • For a force of 10-15 ton-force. single, 220x110x12 mm; coupled, 150x75x8 mm.
  • Up to 25 ton-force. single, 280x140x15 mm; coupled, 180x90x9 mm.

What to make columns of??

Home-made hydraulic press with paired round columns

The press frame columns do not work on bending, as the crossheads do, but on stretching, to which the metal resists much better. But the design of columns largely determines the vibration resistance of the press. The channel in this regard is not ideal, it dampens the vibrations poorly. To test it, tap with a hammer on pieces of channel and square profiled tube. they sound almost the same. The sound of a solid steel bar will be much deafening. In addition, round press columns are good at taking lateral loads, especially if the columns are paired. The press is then as compact and lightweight as possible (see. rice. see right), which makes up for the significantly or completely increase in labor-intensiveness.

Note: if the press is designed for low forces (mechanical assembly and repair work), the round columns of its frame can be made of pipes, see Fig. roller:

How to make a jack press

A solid variety of off-the-shelf household equipment increasingly densely fills store counters and stands. Among the popular, running goods, it is easy enough to choose the optimal model, but when it comes to more narrowly focused tools, the number of options is significantly reduced. Here you find either professional equipment with a space price, or a relatively “budget” domestic with mediocre quality of assembly, which are often distinguished by a half-crafted homemade jack press. With their own hands to assemble such a device, it turns out not only profitable, but also easier, because to find a ready-made device that meets all the requirements, it turns out not always.

Fortunately, the construction of the equipment for pressing is very simple and can be recreated with minimal skills and tools. In addition to the extremely low cost of self-made, you get the opportunity to give the device their own dimensions. Press from the jack for a garage can be made table, hinged, wide or narrow. All possible and impossible upgrades are in your hands: from an adjustable base to a pneumatic drive. Quite enough arguments for self-assembly. All that’s left to do is to want it and get started on the project.

A simple option without welding

Among the most frequent stumbling blocks on the way of self-manufacturing equipment, is the lack of necessary tools or skills for its use. Assembled products must be able to withstand serious loads that materials of appropriate strength can. To strengthen the reliability of fixation of these components when combining often use welding. a reliable, but not the only method of attachment.

In the instruction below, it is clearly shown how to make a jack press at home on the basis of bolt connections, without a single weld. The manufactured device, is capable of producing pressure up to 5 tons and has compact dimensions that allow it to be installed on a table. On this principle, you can easily assemble a floor construction and increase the load-bearing capacity, using a thicker metal when assembling.

  • Profile tube (square) 50x50x600: 2 pieces (for the sides of the frame) and 2 pieces of 50 for the bottom stop.
  • Bend 50x50x380: 4 pcs (for top and bottom brackets) and 2 pcs of 300 for legs.
  • Metal plate 370x50x4 (for mobile beam of jack).
  • Cut from a U-shaped channel or section (for the rails).
  • Plate for mounting the jack, 4 mm thick (dimensions 20 mm larger than the base of the unit used).
  • Metal plate for the jack support, 10 mm thick.
  • M10 bolts and nuts: 16 pcs. (4 for the top beam, 4 for the foot, 4 for the feet, 2 for the springs and 2 for the top stop).
  • M8 hexagonal bolts: 4 pcs (for connecting the guides to the sliding beam).
  • 3/8 bolts: 2 pcs (for connecting the plate with the sliding beam).
  • Bolts ¼: 4 pcs (for fixing the jack to the plate).
  • Rum bolt: 2 pcs (for lower spring attachment).
  • Return springs along the length of the jack (door springs, furniture springs, from trampolines, cars and so on will do).
  • Jack for 5 tons.

The combination of these components can create a strong structure that can withstand 5 tons of pressure. If a component is hard to obtain, it may be replaced with one of a kind. The main thing is that the strength should match, and even better exceed. Such a jack press will be suitable for pressing out bearings, bending and stamping small metal workpieces. To use a more powerful jack, you need to use thicker metal and larger diameter bolts.

  • angle grinder with metal cutting disc
  • Drilling machine or a drill with a set of drill bits
  • Impact wrenches
  • Hexes
  • Taps under M8 and 3/8 (or tighten with nuts)
  • Kern

Let’s start assembling the frame by combining the side crossbars and leg angles. These components will be secured with two M12 bolts and nuts. Drill holes in the middle of the angles and in the bottom of the metal profile, and then insert the bolts and tighten.

The next step is to connect the side crossbars with the top beam, consisting of 2 angles. At the edges of the corners and at the top of the rungs, drill two holes each. For fixing, use bolts M12. While the elements are not fastened, we drill in the corners of the holes for the springs, for the same M12, stepping back from the edges by about 20%.

Between the corners, forming the top beam, an empty space. To create the top stop under the jack piston, we will use a small metal plate, 10 mm thick. Fix it to the corners, a pair of bolts, pitch M10.

To eliminate the possibility of displacement of the jack support, the upper support pad can be equipped with an additional plate with a hole cut out in the center, under the diameter of the retractable screw of the bottle jack.
