Hydraulic Punching  machine YWH21-100T

 

 

Funchion:Blanking, drawing and pressing of plastic materials. Such as: sheet punching, bending, flanging, sheet drawing, fine blanking, cold extrusion of metal parts.

Can also be used for correction, pressing, grinding wheel forming, plastic and powder molding.

 

Featrues:hydraulic transmission, has the advantages of hydraulic and mechanical presses, can arbitrarily change the size of pressing force, not to overload, and can realize the pressing requirements of pressure maintaining and time delay of each step in the process.

 

in order to achieve slider fast air downward and return. the machine is equipped with the growth rate of cylinder, when it comes into contact with the workpiece automatically turn to slow work, reduce the pump displacement and the power of the motor, reduce the noise.

 

the photoelectric protection device can be installed in front of the working platform, and a protective screen is formed on the working platform to protect the personal safety of the operator.

 

Machine tool for centralized button, can realize the adjustment, semi-automatic and automatic three kinds of operation.

 

Therefore, the machine has the advantages of novel structure, reliable performance, complete function and high production efficiency, and is a new generation product of a mechanical press.
