What is the four column hydraulic press?

Among the various types of hydraulic presses, four-column and single-column hydraulic presses are the most common types. The four column hydraulic presses can be used for metal stamping, bending, stretching, extrusion and flanging, as well as press forming of materials. This article will introduce you to more information about this type of hydraulic presses.

What is a four column hydraulic press?

For the requirements of forming the sheet metals, metal strips, or coils, a press is the machine that would be usually applied. The presses come in different forms, and each one of them may differ from the design and the motion driving systems. For the different designs of the presses, the single column press and the four column press are the most common and similar types.

The single-column hydraulic press is mainly applied to the shaft parts, mainly the press-fit of the shaft parts and the correction of the profiles. The multi-column hydraulic press is commonly referred to as a four-column hydraulic press. It has an independent power mechanism and an electrical system. It is controlled centrally by a button to achieve a single-cylinder semi-automatic cycle with adjustable working pressure and compression speed. According to the need, the test can be carried out within the stroke range, and two processing methods can be completed, namely constant pressure distance forming, pressure forming, pressure holding delay and automatic returning action. Four column hydraulic press is a type of press that the motion of the machine is driven by the hydraulic fluids. The four column hydraulic press has four columns as the skeleton, and is able to perform various works, such as stamping, drawing, punching, bending, flanging, forging, cold extrusion, or straightening, etc.
The four-column hydraulic press has an independent power mechanism and electrical system, and it adopts centralized control of buttons to realize single-action semi-automatic cycle operation. The working pressure and punching speed of the machine tool are adjusted according to the needs of the stroke range, and the two process modes of constant pressure and programming are completed. After pressing, there is a pressure holding delay and self-control. Return to exercise.

The parts that form a four column hydraulic press

A four column hydraulic press consists of a hydraulic cylinder, a fuel tank, a hydraulic fluid pump, a motor, beams, four columns, valves, a pressing plate, and others.

1/ The hydraulic cylinder is used to transfer the hydraulic fluid from the hydraulic fluid pump to the motor, which provides the motion driving force to the pressing plate, in order to perform the pressing works on the workpieces.

2/ The fuel tank serves as the device that offers the power source for the press.

3/ The hydraulic fluid pump facilitates the flowing of the hydraulic fluid from the fuel tank to the cylinder by increasing the pressure of the fluid when the pump receives it from the fuel tank.

4/ The motor is driven when the hydraulic cylinder transforms the hydraulic pressure into kinetic energy, and it would further deliver the kinetic energy to the pressing plate to perform the pressing works.

5/ The beams are used to support the four columns as well as other components on the four column hydraulic press.

6/ The four columns that are equipped on this machine play vital roles in the distribution of the pressure. They are each treated with surface medium frequency quenching, and connected with the slide using a wear-resistant ring structure to reduce wear.

7/ The pressing plate is the device that performs the pressing works after receiving the motion given by the motor.
