Basic information

Four-column hydraulic press, also called four-column hydraulic press, is a kind of hydraulic pump as the power source, by the force of the pump to make the hydraulic oil through the hydraulic pipeline into the cylinder, piston, and then the cylinder, piston, there are several groups of seals with each other, the seals in different positions are different, but they all play the role of sealing, so that the hydraulic oil can not leak. Converting hydraulic energy into mechanical energy Hydraulic transmission is a transmission method that uses liquid pressure to transmit power and carry out control. It is especially suitable for aluminum thin plate stretching and aluminum products pressing and forming and stainless steel products pressing and forming.


The four-column hydraulic press is widely used in hardware, gold ornaments, glasses, grinding wheels, electrical appliances, embossing, lamination, metal plates, strap (case, bottom), plastic rubber and other industries. In addition, according to customer requirements, we can also produce pressure-holding type and withdrawal device series hydraulic presses, which can be used for heating, shaping and automatic demoulding of processed products in grinding wheel, case, metal plate, plastic and rubber industries, etc. We can also produce automatic vulcanizing presses with primary and secondary air release devices.


The body of four-column hydraulic press adopts three-beam and four-column structure: it consists of upper beam, slider, working table, column, main cylinder, hydraulic power system and electrical system. The upper beam, slider and working table are made of high quality steel plates welded together and treated by vibration aging to eliminate the internal stress, and the four columns are quenched at medium frequency and chromium plated.


1、The sealing ring of the lower cylinder adopts imported combination ring, which can be used for more than fifteen years without replacement.

2、The hydraulic system adopts cartridge valve, cartridge valve channel is large, large flow, fast, low noise, low heat generation. 3、The electrical control is changed to microcomputer type single-chip computer, the advantage of the system is the safety control voltage of 24V, there is no intermediate relay, no contact, full computer chip stability, long service life and simple operation.

4、Large range of grating safety protection device.

5、The main cylinder and crimping cylinder have upper and lower limit protection, upper and lower limit range protection, upper and lower limit range position setting is simple, convenient and fast.

6、Safety protection device, automatic counting function. Low energy consumption, high efficiency, novel machine model.

 Safe operation

1、The operator of the four-column hydraulic press must be trained to master the equipment performance and operation techniques before operating independently.

2、Before operation, clean up all kinds of debris on the mold and wipe off any dirt on the hydraulic machine rod.

3, installed in the upper and lower mold alignment, adjust the mold gap, do not allow a single deviation from the center, confirm that the mold is fixed and then test pressure.

5、Before working on the hydraulic press, first start the equipment for five minutes, and check whether the oil level of the tank is sufficient.

6、Adjust the working pressure, but should not exceed 90% of the rated pressure of the equipment, test press a workpiece, and then produce after passing the inspection.

7、For different hydraulic machine profiles and workpieces, press fitting, correction, should always adjust the pressure, holding pressure times and time, and to ensure that no damage to the mold and workpiece.

8, the body of the pressure plate up and down when sliding, hands and heads are strictly prohibited into the pressure plate, mold work parts.
