How does four column hydraulic press work?

A hydraulic press is an advanced hydraulic machine that uses liquids as a working medium to transfer power and realize various processes. The four column hydraulic press is one of the common types that use the static pressure of hydraulic oil to transport hydraulic oil to process metal, plastic, rubber, wood, powder, and other products. If you are still confusing about the working principles of the four column hydraulic press, this article will help you.

What is a four column hydraulic press?

For the requirements of forming the sheet metals, metal strips, or coils, a press is a machine that would be usually applied. For the different designs of the presses, the single column press and the four column press are the most common and similar types.

The four-column hydraulic press 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.

How does four column hydraulic press work?

The working principle of the four-column hydraulic machine is that the oil pump delivers hydraulic oil to the integrated cartridge valve block. And the hydraulic oil is distributed to the upper or lower chamber of the cylinder through each check valve and overflow valve, and the cylinder is moved under the action of high-pressure oil.

The hydraulic drive system of the four-column hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism and a working medium. The power mechanism usually uses an oil pump as a power mechanism. In order to meet the requirements of the speed of the actuator, an oil pump or multiple oil pumps are used. Gear pump for low pressure; vane pump for medium pressure; plunger pump for high pressure. The four-column hydraulic press is simple, economical and practical. The appearance is in the shape of an octagonal. The control electrical box is made of a glass door, PLC computer control or ordinary electrical appliance. It has the advantages of reliable work, intuitive operation and convenient maintenance.

The four column hydraulic press can be operated with manual, semi-automatic, or fully automatic forces. For the manual operated press, the operators can manage the machine with the manual control valve and the pressure gauge that is equipped on the side of the machine. The semi-automatic operation refers to the permission for the operators to adjust the working pressure and the pressure speed, etc. As for the fully automatic operation, the adjustments can be done when the machine automatically detects the requirements. To operate the four column hydraulic press, the hydraulic fluid pump delivers the hydraulic fluid from the fuel tank to the hydraulic cylinder. At that time, the hydraulic cylinder transfers the energy to the motor, and thus drives the pressing plate. Once the pressing plate receives the energy from the motor, it presses on the workpieces with downward and upward orientations. Through the adjustment of the different working pressure and speed, the required geometries can be successfully formed on the products.
