Which hydraulic press factory brand is good in Foshan

Product information

Name: 500t ton four-column hydraulic press, four-column hydraulic press.

Brand: Chengda hydraulic

Model: YB31-500C


500tons four-column hydraulic press use a wide range of hardware, gold ornaments, glasses, grinding wheels, electrical appliances, embossing, lamination, metal plates, watch straps (shell, bottom) plastic rubber and other industries products molding with. In addition, according to customer requirements, we can 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 machine with primary to secondary air release device.


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


1、The plunger of the lower cylinder adopts hard chromium-plated steel parts with wear-resistant ring structure to avoid the problem of plunger cracking.

2, the lower cylinder seal ring using imported combination ring, can be used for more than fifteen years without replacement.

3、The column and piston rod are heat-treated by medium frequency, and the surface is plated with hard chrome.

4、The receding cylinder can be controlled separately by pointing.

5、The hydraulic system adopts cartridge valve, cartridge valve channel is large, large flow, fast speed, low noise, low heat generation. 6、The electrical control is changed to microcomputer type single chip, the advantage of this system is the safety control voltage of 24V, there is no intermediate relay, no contact inside, the whole computer chip has high stability, long service life and simple operation.

7、Large range of grating safety protection device.

8、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.

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


1, the oil industry for strict filtration before allowing to join the oil tank.

2, the slider should often inject lubricating oil, the exposed surface of the column should always be kept clean, before each work should be sprayed with oil.

3、The maximum allowable eccentricity is 40mm under the nominal pressure of 500T. The eccentricity is too large to make the column strain or other undesirable phenomena.

4、The machine should be scrubbed clean and coated with anti-rust oil on the surface of each plant.


1、Calibrate the pressure gauge once every six months.

2、Do not overload or exceed the maximum eccentric distance to use.

3、Check regularly whether the hydraulic oil of the equipment is reduced.

4、Working fluid should be replaced once a year, of which the first replacement time should not exceed three months.

5、If the machine is out of use for a longer period of time, the surface of each part should be scrubbed clean and coated with anti-rust oil.

6、When using, observe whether oil leakage or other abnormalities, such as unreliable, noisy, vibration, etc., to stop and analyze the causes.

7、Operate to observe the pressure change, if to the specified pressure does not jump then to promptly turn off the power switch, so as to avoid excessive pressure resulting in equipment failure, while overhaul.

8, pay attention to safety, the operator should be trained for the job.

9、At the end of each day's work, place the slider in the lowest position.
