Performance characteristics:

1. The machine body is of casting or steel plate structure, linear design, uniform stress, good rigidity and beautiful appearance; Low temperature tempering is used for stress relief.

2. The crankshaft is laid horizontally, and the transmission system is placed on both sides of the machine body. The structure is compact, the layout is reasonable, and the transmission is stable.

3. The rotary key type rigid clutch is adopted, with reliable performance and sensitive action.

4. It is guided by four sided guide rails, with high running accuracy and effectively prolonging the service life of the die.

5. Belt brake, there is a collapse type safety block in the slider to ensure the safety of the press; The structure is simple and convenient for maintenance.

6. Above 200T, pneumatic double balance structure is adopted to balance the weight of sliding block and upper mold, so that the press can run stably.

7. The centralized and decentralized lubrication system is adopted, which is economical and reliable, and ensures that there is sufficient oil in all lubrication parts.

8. The extra large frame with external support improves the stability and safety of machine tool installation and operation.
