How to make a hydraulic press with their own hands

The principle of operation of the hydraulic press

Device for pressing, made by your own hands, is not inferior in its quality and technical characteristics to its factory counterparts.

As you can see in the photo of the homemade press, it can be used in the home for various needs, whether it be:

In addition, the presser device can be useful:

Purpose and function of the presser: applications of the device

The press has a wide application. Sometimes it is a necessary item in the workshop or in the garage. A small device is often used in the repair of cars. You can use a press for silent blocks, as well as to press out the bearings.

Such equipment is used to create briquettes of waste, when gluing two surfaces, as well as for bending parts of metal. At the same time, factory devices may be unaffordable for many. If you decide to make such a device with your own hands, it can easily be adapted to specific tasks.

The hydraulic principle makes life a lot easier. Thanks to a simple mechanism, different equipment works effectively.

Self-made unit is used for work in the garage and workshop


So, let’s consider in more detail what is necessary for such a device:

  • Pressing out different bearings, then it is used in small car repair shops;
  • Bending metalware of various shapes;
  • Providing pressure to glue the two elements;
  • installation of rivets.

Try to make a press with your own hands in the garage. Such a device is used for pressing and pressing in all kinds of parts. This equipment produces a huge range of repair, maintenance and preventive maintenance.

  • Even a small car service center needs a hydro-press, which can be purchased or made by your own forces. To make such a machine you need to decide on the installation of the pressure gauge, mass, dimensions and parameters of the piston. Before developing the press it is necessary to take into account the models of cars. The simple design is not suitable for large machines;
  • For the workshop and at home often need a press for waste paper. If there is a large accumulation of paper, it must be disposed of. This construction has a medium power rating and can be operated from the mains. With the help of a small machine you can remove a significant amount of waste paper;
  • The cardboard press, which can be used to press plastic bottles and tin cans, is also useful. When installing the machine by yourself, you need to consider the parameters of the piston, the bed, the size of the equipment and weight. In such a device a ready-made or manual hydraulic pump is used;
  • sawdust press is used to create briquettes. The resulting briquettes are used for heating private homes. Such a device consists of a table, power frame, base and drive. A jack is often used for the manual mechanism, while an electric motor is suitable for the mechanical design;
  • Homemade baler for hay is a special box, which is installed on a frame structure made of beams. Such frames can be made of metal profiles. The structure is made in the form of a box, but without the upper part. You will need some materials for making a press for hay with your own hands. Drawings with dimensions make the task easier. It is worth using angles, metal slats and treated boards.

To make a machine for hay, you need to connect the boards with metal corners. After that the box is lined with slats. This will give strength to the product. Then you need to proceed to the wicket or door, which is fixed on the hinges.

For assembly we need an element for attaching to the headstock, a base for mounting all the components, a running gear and a transport pickup. You will also need a special chamber with a gearbox and hay. The bale pickup machine is used for one cycle of packing and collecting straw or hay.

This makes it possible to pick up the dried hay in the field, as well as baling the bales. Then bales are formed from the webs. This process is characterized by bailing without deforming the vegetation. Factory pickups have a fairly complex device, which is rarely possible to make at home.

Collectors for waste paper are used at the points that are engaged in receiving various secondary raw materials. Such a machine is characterized by an increased pressure of about 15-50 tons, which helps make small bales. Some kind of manipulator can be used for loading them. Presses for fuel briquettes also have great power.

A similar construction can be made of two types:

  • The mechanical version represents a simplified design with low power. In this case, the force can reach one ton;
  • to the more powerful refers a homemade hydraulic device, the power of which can be up to 4 tons.

Similarly, the manufacture of a press for plastic bottles is done.

Press for juice squeezing: types, device and how to make it with your own hands

Owners of gardens, vineyards and berry plantations are well familiar with the problem of processing the harvest. An effective way to solve it. cold juice squeezing. This process allows to save vitamin values of fruits and berries for a long time, without construction of voluminous storage.

The main mechanism of a dacha “canning shop” is a juice squeezer. It helps to process hundreds of kilograms of ripening crops quickly and without losses.

About the existing varieties, operating principles and cost of juice production equipment we will talk in this article. For home masters will be useful information about the features of independent production of a powerful “juicer”.

Types and principles of operation of juicing presses

Devices designed for squeezing juice are divided into mechanical, hydraulic, electro-hydraulic and pneumatic.

The most common mechanism is a mechanical screw press.

Screw press for juicing is simple and reliable

The principle of its work is clear at a glance: in a container with holes laid chopped fruit, poured grapes or berries. Then the screw, which lowers the flat piston, is actuated by turning the handle. The extracted juice flows through the holes in the casing into a pan and from there into jars or other containers.

In addition to stainless steel, hard beech wood is used for making the casing. It is used to make a drainage grid. It consists of two halves, connected by metal hoops.

An upgraded version of such a device. a manual hydraulic press for apples and grapes.

It does not have a perforated juice collector. Instead, it uses several wooden drainage frames. Sacks with milled material are placed between them. Manual hydraulic jack develops a great force (from 1 to 5 tons). Thanks to this method the volume of juice obtained reaches 70% of the volume of fruit.

The original way of squeezing implemented in the hydraulic press Grifo (Grifo). It does not have a hydraulic jack, but instead has a powerful “keg” diaphragm. It expands under the pressure of tap water (1.5-2 atm).) and squeezes the juice through the perforated wall of the housing.

The pneumatic press works on a similar principle. Only the squeezing diaphragm is not filled with water but with compressed air from a compressor.

Since all juice presses work in tandem with choppers, it is necessary to say a few words about these devices as well. The simplest mechanism is a steel drum-grinder, placed in a casing with a loading neck. The chopper is actuated by turning the handle, turning the fruit into fine crumbs-mezgah.

A more advanced version is a device with an electric drive. Minimum physical effort and maximum performance are the main arguments in its favor.

It should be noted that the productivity of mechanical presses is low (10-30 liters per hour). Nevertheless, it is quite enough for most cottage farms.

To improve the quality and increase the yield of juice use two ways:

Both methods allow the juice to drain out of the center of the juice chamber. Without this drainage system the middle layers of chopped fruit are squeezed out less well than the upper and lower layers. An additional benefit of using pouches is the release of juice from the pulp.

Higher throughputs require an electric drive. Here you can distinguish two types of equipment: the traditional screw mechanism, driven by a pair of “electric motor-hydrodrum” and auger press, working on the principle of a meat grinder.

A screw press juicer with an electric motor is designed for processing berries, grapes and tomatoes. Grinding the raw material, the screw presses it through a sieve and produces a juice with a lot of pulp.

Approximate prices

For a manual press that can hold 25 liters of raw material, you have to pay at least 20,000.

Average Pneumatic apple juice press can be bought for 34,000. For a hydraulic diaphragm-type device, sellers ask 94,000.

Types of machines that are usually made by hand

The most common presses made at home are:

These types of tools are most suitable for use at home or in the garage, because they take up little space.
