Benefits & Features

Main features

-steel plate welded frame

-temperature treatment for high rigidness

-transmission with wet clutch and two big gears

-applicable for progressive die stamping

-capacity from 110ton to 315ton

Wide table suitable for progressive die and muti-station die stamping

Wider bolster and slide plate than single crank press, suitable for big size tools. C type body, open back, easier for side coil sheet feeding or front to back sheet feeding. Two tonnage center points, bigger power at ram sides. Bolster surface grinding, higher flatness.Customized scrap dropping holes in bolster. Bolster and slide plate sizes are customizable. Standard T slots in bolster and slide plate.

Reverse rotated double crankshaft of the gap frame press machine

Double crankshaft, 42CrMo forged and rolling treatment for more smooth surface. Reverse rotated to eliminate the lateral force. Copper conrod bush, high quality front and rear shaft bushes, all grease lubricated. Ball screw nitrogen treatment with high hardness. Proper two transmission gears timing.

Big torque wet type pneumatic clutch with solenoid valve

Self-produced high quality wet type combine clutch and brake, reliable and easier maintenance. Toyooki/Taco/Ross brand dual-safety solenoid valve controls the clutch and brake working properly. Air pressure meter of clutch with safety air pressure switch ensures properly and safety opertation of the crank punching press. Safety clutch cover is also standard equipped.

Friendly easy operation HMI for automatic press machine

LCD touch screen with setting and monitor functions. Operator can set the lubrication frequency and time, the cam angles, the cam controller type through the screen. Crankshaft angle indicator light, lubrication and overload alarm lights are easier for operator to check the press working status. Emergency stop button, working mode selecting swithes, overload reset switch are located on the panel. Counter and pre-set counter is convenient to arrange the production plan.

Automatic powe press central control system
