JH21-25T Punch Press C Frame Single Crank Eccentric Mechanical Power Press Machine Tool
1. Steel welded body, tempering treatment, high rigidity, accuracy and stability;
2. Vertical located crankshaft, compact structure;
3. The crankshaft undergoes grinding treatment after high frequency quenching;
4. Lengthened rectangular guideway with a surface of bronze plate;
5. Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact;
6. PLC control and imported safety dual valve;
7. Wet clutch and hydraulic overload protector.
Standard Execution:
Heavy, one-piece welded steel frame is designed to resist deflection, providing more accurate stampings and longer die life.
Fast-response hydraulic overload relieves the pressure of a tonnage overload in milliseconds, stopping the press immediately andprotecting press and dies from damage.
Wet clutch and brake provide long life, very low maintenance, and high performance even at high single-stroking rates.
