JH31-200 closed hot forging press

The press is the ideal type in the forging industry in recent years, which is mainly used for the hot forging process of small and medium-sized parts, and also for the forging of the connecting rod, gear, bearing ring and other parts.
 
The Features of Performance:
 
The machine is equipped with a special feeding and discharging device to meet the requirements of forging technology.
 
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 equipment is equipped with the hydraulic overload protection device, once jamming can be solved by unscrewing the screw plug on the unloading valve and releasing the oil in the cylinder.
 
The travel speed is fast, which reduces the contact time between forgings and molds, thus improving the service life and working efficiency of molds. The side of the frame has a feeding port, which is more convenient for the feeding of forgings.
 
The machine adopts Italian pneumatic dry friction clutch, which is controlled by double valves, has the advantages of smooth operation and low noise.
 
The lubrication system is equipped with manual, motorized, automatic thick oil or thin oil lubrication according to the needs of users.
 
Electric control system adopts common relay and PLC electrical control for optional.
