J31-100 closed hot forging press

 
J31 series closed hot forging press is widely used in forging, trimming, punching and rough forging of auto parts, standard parts, nuts, special forgings. It can also do blanking, stretching and bending of various parts and so on, which is the ideal type of domestic forging industry.
 
The Features of Performance:
 
The machine is equipped with a special feeding and discharging device, which can meet the requirements of forging technology and save money for users.
 
The machine has a welded structure with steel plates, which has the advantages of strong rigidity and no deformation through tempering treatment.
 
The steel helical gear rotation has the advantages of stable operation, low noise, and not easily damaged. 　
 
The machine adopts a rigid double-key pneumatic traction clutch, which is simple operation and impact resistance and can effectively overcome rebound when stamping.
 
More than 160 tons models are equipped with double balancers, which can effectively balance the weight of the slider and the upper die, reduce the impact noise and prevent the slider from falling. Collapse fuse is easy to replace.
 
Manual, automatic and lubricating systems are optional according to users' requirements.
 
This machine is equipped with an electric molding-adjustment device, which saves time and effort and improves efficiency.
