Product description

YB28-150T four-column double-action hydraulic press, also known as four-column double-action hydraulic press, is a special hydraulic press made by our factory for aluminum and stainless steel product factories, especially for aluminum sheet stretching and aluminum products pressing forming and stainless steel products pressing forming. Our company Chengda Hydraulic has been focusing on hydraulic press for 30 years, mainly producing four-column hydraulic press models: 100-ton four-column hydraulic press, 150-ton four-column hydraulic press, 200-ton four-column hydraulic press, 300-ton four-column hydraulic press, 500-ton four-column hydraulic press, etc.  


YB28 series four-column double-motor is designed and manufactured on the basis of the original YB32 series with improvements. In addition to maintaining the original technical performance, compared with YB32 series, it also has the following characteristics:        

1, the same tonnage machine cylinder stroke is increased, the working table is increased.

2, no-load running speed is higher.

3, with fast stretching and general speed stretching two stretching speed.

4、The whole machine runs more smoothly and has more stable performance. 


1、The plunger of the lower cylinder of the four-column hydraulic press is made of hard chromium-plated steel parts with wear-resistant ring structure to avoid the problem of plunger cracking.

2、The sealing ring of the lower cylinder of the four-column hydraulic press adopts imported combination ring, which can be used for more than fifteen years without replacement.

3、The column and piston rod of four-column hydraulic press adopt medium frequency heat treatment and hard chrome plating on the surface.

4、The rewind cylinder can be controlled individually by pointing.

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

7、Large range of grating safety protection device.

8、The main cylinder and press side 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) Check whether there is any strange noise during the operation of the machine.

(2) Check whether there is any strain on the surface of the piston rod of the main cylinder of the working cylinder.

(3) Check whether the upper and lower dies are firmly installed.

(4) Check whether the electrical operation switch, limit and indicator are normal.

(5) Check the oil cylinder and replace the seal if there is oil leakage.

(6) Find serious wear and tear wearing parts should be promptly notified to the maintenance personnel to replace in a timely manner.

(7) Thoroughly clean the equipment surface oil once a week.

(8) Regularly clean and replace the linoleum on the sliding beam, taking care not to touch the surface of the column.
