This machine is used for cutting, compacting, molding, punching, bending, etc. of metal and non-metal parts. The pressure and force factors in the hydraulic device are air or fluid pressure. While introducing the types of hydraulic industrial press machines, we must say that this machine itself has sub-sets that are categorized according to accuracy, speed and amount of power. These items are:
* Press to create laminate
* C-frame
* Manual lever
* Assembly
* Power press
مان Application of hydraulic presses
Hydraulic press machine has various applications and is used in various industries. Common cases of these industries are:
🔹 molding hot glass and thinning them
🔹 shaping and molding in the cosmetics industry
🔹 pharmaceuticals and forming pills
🔹 plastic injection
🔹 bending in various industries
🔹 shredding car papers
🔹 leaving Fat from cocoa
🔹 knife making and molding industry
How to operate the hydraulic presses
Hydraulic press machine is a device that is designed based on the transmission of power in a fluid and can be used to compact various objects under high pressure. In these devices, the role of hydraulic fluid is very important and central, and it is responsible for power transmission. If you have used hydraulic steering or a hydraulic jack, you will notice that the force you apply is much less than the change you make.
This force should be equivalent in direct transmission mode. But the use of Pascal's law has made it possible for the hydraulic press to lift very heavy objects or compress very strong objects with very little force. We have mentioned using Pascal's law in hydraulic devices. Pascal's law states that the change in pressure at any point of an incompressible fluid is transmitted to all points and the surface of the liquid. This relationship is expressed as P=F/A. Here it is clear that pressure and force change under the influence of surface or A. Now, if you pay attention to the image shown, we are facing two cylinders of different size, namely surface A1 and surface A2. On the other hand, the hydraulic fluid used on both sides is the same.
According to Pascal's law, P1=F1/A1 must be the same as P2=F2/A2. Since both fluids are the same, the area and applied force must be changed to create this balance. In the picture, we showed that on the side where we apply pressure, the cylinder and piston are smaller. Therefore, less pressure is applied to it to be changed on the opposite side of an object with a larger area and a larger size. A small one enters and on the other side it causes a large piston with a very heavy weight to move. As a result, the movement of the big piston causes a lot of pressure on the workpiece and leads to its compaction or so-called crushing.
