500t ton frame hydraulic press


Name: 500 tons frame hydraulic press, 500 tons frame hydraulic press

Brand:Chengda Hydraulic

Model:YB-500A frame hydraulic press

Basic information

500 tons frame hydraulic press, the appearance of hydraulic press is "frame type". It is a kind of machine that makes the hydraulic oil circulate in the oil tank through the one-way valve to make the cylinder and piston do the work so as to complete certain mechanical action as a kind of productivity.


The 500-ton frame hydraulic press is suitable for hardware, gold ornaments, glasses, grinding wheels, electrical appliances, embossing, laminating, metal plates, strap (case, bottom), plastic rubber and other industries. In addition, according to the customer's requirements, we can also produce pressure-holding type and withdrawal device series hydraulic presses, which are suitable 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 machine with primary to secondary air release device.

Structure composition

The main structure of frame hydraulic press is composed of main body, main cylinder, ejector cylinder and liquid filling device. The power mechanism is composed of oil tank, high pressure pump, low pressure control system, electric motor and various pressure and directional valves. Under the control of electrical device, the power mechanism controls the flow, flow direction, pressure of hydraulic oil and the working sequence of hydraulic actuator and protects the hydraulic circuit through the pump and cylinder and various hydraulic valves and control valves.


(1) The frame frame has good overall rigidity and high compressive strength, and the pressure, stroke and pressure-holding can be adjusted according to the requirements of the pressing process.

(2) It has different derivatives such as lower top material, upper item and upper and lower compound top material or shallow drawing depth, which are suitable for the needs of various pressing and forming processes.

(3) The press starts quickly after the mold is closed, and it only takes a few seconds to reach the rated pressure.

(4) Adopt the lower type oil tank, easy to change and clean the oil tank.

(5) Stable quality and reliable performance in mass production.

(6) The electrical control is changed to microcomputer type microcontroller, the advantages of this system are 24 V safety control voltage, no intermediate relay and no contact inside, full computer chip stability, long service life, simple operation and large range of grating safety protection device.

Working principle

The hydraulic pump is the power source of the hydraulic system, which relies on the force of the system to make the hydraulic oil enter the cylinder piston through the hydraulic pipeline. Finally, through the check valve, the hydraulic oil is circulated in the injection box ring, so that the piston can do the work to achieve the conversion of energy, regulation and transportation, to complete the cycle of various process actions. Hydraulic cylinder converts hydraulic energy into mechanical energy. Hydraulic pressure is a kind of transmission method that uses liquid pressure to act and control.

Safe operation

1、Start the equipment test pressure, check whether the pressure reaches the working pressure, the equipment action is normal and reliable, there is no leakage.

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

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

4、When the body platen is sliding up and down, it is strictly forbidden to put hands and head into the platen and mold working parts.

5、It is strictly forbidden to apply pressure at the same time, the work of the enemy, stretching, welding, pressing snow, twisting and other operations.

6、The hydraulic machine press ask side shall not smoke, welding, fire, shall not store flammable and explosive substances, good fire prevention measures.

7, hydraulic press work is completed, should cut off the power, the hydraulic lever of the press wipe clean, add good lubricating oil, the mold, the workpiece cleaned dry net, neatly arranged.
