300t ton four-column hydraulic press features


Name: 300 tons four-column hydraulic press, three-beam four-column hydraulic press, 300 tons hydraulic press

Brand: Chengda hydraulic

Model: YB31-300C four-column hydraulic press


Four-column hydraulic press is widely used in hardware, gold ornaments, glasses, grinding wheels, electrical appliances, embossing, lamination, metal plates, watch straps (shell, bottom) plastic rubber and other industry products molding. 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 the industries of grinding wheel, case, metal plate, plastic and rubber, etc. We can also produce automatic vulcanizing presses with primary to secondary air release device.


The body of four-column hydraulic press adopts three-beam and four-column structure: it is composed 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 welded with high quality steel plates, which are 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, 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.

Four-column hydraulic machine cooler is corroded troubleshooting methods:

A. The following exclusion method should be used: in the four-column hydraulic press, choose aluminum alloy, titanium alloy and other corrosion-resistant materials for the cooling tube. With stamping and forming aluminum sheets stacked together as heat transfer fins, this structure greatly increases the heat transfer area of the cooler and improves the production process.

Second, improve the cooling water quality. Should be set to stabilize the cooling water system water quality of effective water quality control devices, should be set up filters or decontaminants. When the general open cooling water system can not meet the water quality requirements of refrigeration equipment, it is appropriate to use closed cooling tower or set up an intermediate heat exchanger.

Third, the cooler corrosion will cause a very negative impact on the four-column hydraulic press hydraulic system, in order to avoid this situation, in addition to regularly check the working condition of the cooler, once the abnormal appearance, should be dealt with in a timely manner.
