Overload Protector for Press
( Overload Protector for Press )
“Overload Protector” is equipped in Press machine to check hydraulic pressure of cylinder inside the slider. If happen overload, the hydraulic pressure of cylinder will be released immediately within 3/1000 seconds. It has pressure control valve inside of overload protector, which can adjust hydraulic pressure automatically and eliminate the impact of rising pressure (which cause by oil temperature rise) in pressing process.
Air Driven Hydraulic Pump
( Air Driven Hydraulic Pump )
“Air Driven Hydraulic Pump Unit” use air to drive hydraulic pump. Once outlet hydraulic pressure reached setting pressure, it will stop driving and won’t waste energy. If pressure reduce, it will add automatically. It can maintain pressure for one year. It is used for slide lock, feeder, stick release and hydraulic pressure supply system which needs to maintain pressure for a long time but less operate.
P.C. Board Piercing System
( P.C. Board Piercing System )
The system employs hydraulic pressure for activating the platen to knock out. It is totaly different from the conventional mechanical structure, and can prevent the board and the dies from being heavily impacted by the press, thus minimize the breaking of pierce pin and prolong the dies service life. To collocate Quick Die Change System can shorten the time of die change and ensure the operation safety.
