Product Description

25 ton c frame crank type small pneumatic power press

C frame mechanical power press is widely used for sheet metal stamping, piercing, trimming and bending process. The power press could work with single punch die and progressive die to produce home appliance parts, tv brackets, auto parts, utensils and similar stamping parts. The press could work with NC feeder decoiler system to act as an automatic press line.

Features:
1. Steel welded body, tempering treatment, high rigidity, accuracy and stability;
2. Vertical located crankshaft, compact structure;
3. The crankshaft undergoes grinding treatment after high frequency quenching;
4. Lengthened rectangular guideway with a surface of bronze plate;
5. Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact;
6. PLC control and imported safety dual valve;
7. Wet clutch and hydraulic overload protector.
8. CE certificate



Details:
1. Steel plate welded c frame body, heat treatment, produced by cnc boring and milling center, high rigidity and precission
2. Wet type pneumatic clutch with safety solenoid valve, lower noise and longer service life.
3. Best quality gears, bushes, cylinders, link rods and ball screw ensure the high performance, high reliability and longer service life.
4. Hydraulic overload protected system is standard equipped. The press will stop with oil pressure release if overload to protect the press and the die. It is easy to reset to normal status.
5. PLC control, Omron or Panasonic brand, high quality with global warranty.
6. Double hands control buttons, touch screen control panel, cam controller with encoder.
7. Slide adjust motor is equipped on the back of the slide. This position is better to protect the motor and the press is more compact in this way. The slide is motorized adjusted with digital displayer.
