H FRAME STRAIGHT SIDE BODY

JS31 straight side press uses a strong H frame body. 125ton, 160ton and 250ton presses bodies are casting iron integrated type. 315ton, 400ton and 500ton press body can be casting iron or steel welded. 630ton and bigger presses bodies are steel welded and the body can be disassembled as the crown, slide, table and columns which are fixed by tie bolts.

The press body will be heat treatment and sand blasting. Press structure is optimized by computer and all the key power points are strengthened.

ECCENTRIC GEAR TRANSMISSION

JS31 H frame single point press uses eccentric gear transmission system.This type press is more suitable for thin drawing, thick sheet blanking and hot forging process. Eccentric gear transmission system ensures bigger stroke length and bigger nominal tonnage stroke length.

The grinded helical gear or herringbone gear makes the moving more stable with lower noise.

DRY TYPE PNEUMATIC CLUTCH AND SEPARATED BRAKE

Press with pneumatic clutch can work as continuous, inches or single stroke,more choices for operators. Brake system can stop the press at any point especially for emergency stop.

Dry type separated clutch and brake, smooth working and easy for maintenance and repair.

SAFETY

JS31 straight side eccentric gear press is standard equipped with hydraulic overload system. Normally the system is set as 110% of the nominal capacity.

The press will stop immediately once it is overload than 110% to protect both the press and the die. It is easy to reset the overload as there is a reset switch on the control panel. The system can be reset within 3 minutes.

Double-hand control buttons give another safety system as the operator must press both buttons at same time to avoid putting hands into the working area.

Light barriers are optional to protect the operator hands when press is working.An emergency stop button on the panel can stop the press immediately once press the button down.
