What is a press machine?
The press machine is one of the advanced devices for cutting or shaping industrial parts that have different components. Each of the parts of this machine tool has a specific task to apply pressure to industrial equipment that may use hydraulic, pneumatic or mechanical pressure for cutting or shaping. The press machine is produced in different brands and shapes all over the world, and the use of each one is also different. For example, shaping sheet metal for automobile production to pressing plywood to create curved pieces in furniture making are all applications of press machines.
Pressing
1. The hydraulic presses machine
One of the best press machines that is used by most industries today and is very popular in the industry is the hydraulic press machine. The high power and excellent performance of this machine have made it the choice of many industries for shaping or densifying industrial parts. This machine tool enters the market in small and large sizes, and each industry can use certain dimensions of this machine according to its needs and production volume. The operation of the hydraulic press is very simple. In this way, first a very small and simple force must be applied to one side of the hydraulic device by human forces or mechanically. Then this small pressure can create a very large force on the other side of the device that is capable of pressing and crushing objects. Therefore, it can be said that the hydraulic device does not even need to spend a lot of energy to press the objects.
The basis of the operation of the hydraulic press is the transmission of force in the fluid. When there is a need, industrial parts or metal and wooden objects are transformed into different shapes under high pressure, they use this device. In this machine tool, hydraulic fluid is used, which is placed on both sides of the device. On one side of the hydraulic press, there is a cylinder and a small piston, applying less pressure to it causes a large piston with a heavy weight to move on the other side. When this piston moves, a lot of pressure is applied to industrial parts or objects, which will cause them to be crushed or deformed. The hydraulic press machine has various applications and is usually used as a metal press machine; Because changing the shape of some industrial metals is not a simple task.
2. Mechanical pressing machine
Mechanical press machine is another useful industrial tool that is used as industrial machinery to shape and compact parts. In this device, the rotational force of the engine is used to apply pressure to the surface of objects. In this machine tool, there is a converter that can produce rotational force in a specific direction. From the rotation of the motor, a certain energy is produced, which is used to press metal parts or other industrial parts. All the power and energy resulting from the operation of the mechanical press is caused by the rotation of the motor. With a simple comparison between the hydraulic press machine and the mechanical press machine, it can be seen that the mechanical press machine tools produce pressure to industrial parts in a shorter period of time and with better performance. Just like a hydraulic press machine, human power or machine operator can control the amount of pressure applied to industrial parts. Because the high speed of the mechanical device may change the shape of the industrial parts too much.
3. Crankshaft Press or Press Mail Long
Another industrial press machine that is widely used in various industries is the crank press machine or crank press machine. In this device, the rotating force of the electric motor produces energy, and as a result, it produces the necessary force to move the pistons. In other words, the rotational force becomes a compressive force. When one or more pistons move, they will be able to apply pressure to a large number of industrial parts at a given time and change them in desired shapes and sizes. The crank press machine or the crankshaft metal machine is used when large industries want to change the shape of a large number of industrial parts at the same time. In this device, a crank is connected to the control shaft and causes the pistons to move vertically up or down.

Kunkel press machine or nodal connection includes a very powerful electric motor that is specially connected to other parts of the press machine. The energy from its rotation can provide the necessary force for pressing and compacting industrial parts. Of course, there are structural differences between the Konkel press machine and other press machines. This machine has a part called crank, which, unlike other press machines, rotates in all directions and in all axes. This is the reason why a knot press machine can be used to press industrial parts that are in a vertical or horizontal position. The power input from this machine tool is very high to the level of industrial parts and it is very easy to work with it.
5. The centrifugal press machine
Another press machine that has almost the same function as the crank press machine is the centrifugal press machine. This machine tool also includes an electric motor that rotates continuously in the off-center part and is connected to a rod. The rotational energy of the electric motor is directly transferred to the rod. This rod is located inside a slide-like structure that starts to move quickly after receiving energy from the electric motor. The movement of the connecting rod in total causes the movement of the piston of the device. In this case, the piston moves up or down and applies the standard pressure to the surface of the industrial parts. One of the reasons why this machine is called a centrifugal press is that the rod is not exactly in the center and its correct position is outside the center of the machine tool. For this reason, it can make the piston move by using centrifugal force.
6. The gear presses machine
In this press, gears are used to transfer power and energy. While in other devices, cranks or things like this are usually used. When the electric motor produces the necessary energy and power by using its rotation, it quickly transfers it to the gear and thus the power is transferred from one side of the device to the other side of the device. The gear is directly responsible for power transmission and provides the necessary pressure for the compression of industrial parts. The way to transfer power and energy from the electric motor to the gear is very simple. First, the necessary force is produced by rotation in the electric motor, and this force causes the rotation of the gear in the next step. Of course, in the gear press machine, one gear is not used, but several gears will be used. These gears start to rotate and move in a certain direction, and the amount of pressure or the duration of pressure applied to the surface of industrial parts can be adjusted in this device.

As the name of this press is clear; To transfer power and energy from the electric motor, a big screw is used instead of a gear. First, the electric motor starts rotating, and in the next step, it transfers the generated energy to the screw and causes the screw to rotate. These presses were designed manually in the past. First, human power rotates the handle of the press machine and in this way, it produces the necessary pressure to compact the industrial parts. But today, electromotor energy is used for pressing.
