Details:1.The JH21 C-frame single crank press is suitable for processing lightweight and thin materials through blanking, piercing, bending, forming, and can be integrated with ROT lines or transfer units. It is ideal for both single and progressive die applications, with a capacity ranging from 25 tons to 400 tons.
2.The press uses a high torque and low noise wet clutch and brake system.
3.A steel-welded body ensures a rigid frame with minimal deflection.
4.High-precision transmission gears and a rigid crankshaft ensure long life and accuracy.
5.A forced lubrication system with a default monitor guarantees reliable operation.
6.User-friendly design and an all-function electric control system make it easy to attach accessories.

FEATURES:
1. Steel-welded body with tempering treatment or VSR (Vibratory Stress Relief) for high rigidity, accuracy, and stability;
2. Pneumatic dual balance cylinders to reduce noise and impact by balancing the slide and punch weight;
3. Crankshaft undergoes grinding treatment after high-frequency quenching;
4. Extended six-face rectangular guide with a bronze plate surface;
5. Vertically located crankshaft for compact structure;
6. PLC control and imported safety duplex valve;
7. Wet-type combined multi-disc friction clutch and brake; hydraulic overload protection pump.
