H FRAME BODY WITH HIGH RIGIDITY

JW31 straight side press machine uses a strong H frame body. The press body is steel welded

with high quality steel plates by carbon dioxide arc welding. After welding, all the weld seams must pass the examination of ultrasonic inspection. The top transmission gearbox is tested by oil bath to avoid any oil leak.

Then, the press body will be heat treatment and sand blasting. All these treatments will help to release the welding stress for high rigidity. Press structure is optimized by computer and all the key power points are strengthened.

Hydraulic Overload Protected Pump

The press is standard equipped with Japanese SHOWA hydraulic overload pump. 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.

Panasonic or Omron or Schneider PLC

PLC control system can be Panasonic or Ormon or Schneider brand.

OPERAITON AND MAINTENANCE

JW31 pneumatic press is PLC control with HMI and cam controller. The press has both mechanical and electrical cam controllers. It is easy to set the cam angles to match the press with automatic NC feeders or press transfer system. HMI has the function as with system setting, lubrication setting, I/O monitor, counter setting and TDC reset.Auto grease pump is standard equipped on the press and the operator can set the lubrication frequency by the HMI according to the working time or working stroke times.

Operator only needs to check whether enough grease in the cup every working day.Press ram is adjusted by brake motor with a digital shut height indicator. Precision is 0.1mm.There is a button and an up/down selection switch on the control panel. So easy to test the die height when install the die or change the die.
