Product Description

Eccentric Type 200 ton Metal Stamping Punching Press

Product Description

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.

Key Features:
1. Heavy-Duty Steel Welded Frame
Constructed with high-grade steel and tempered for maximum rigidity, ensuring long-term dimensional accuracy and operational stability under high loads.
2. Cross-Located Crankshaft Design
Optimized cross-positioning of crankshaft minimizes footprint while maintaining structural integrity, ideal for space-constrained production environments.
3. Precision-Ground & Heat-Treated Crankshaft
Undergoes high-frequency quenching followed by precision grinding for enhanced wear resistance, smooth operation, and extended service life.
4. Bronze-Lined Extended Rectangular Guideway
Features an extended guideway with bronze-plated surface for reduces friction, improved wear resistance, and consistent precison over prolonged use.
5. Pneumatic Dual Balance Cylinder System
Counterbalances the slide block and punch weight through pneumatic cylinders, significantly reducing noise and vibriation during operation.
6. Advanced PLC Control with Safety Dual Valve
Equipped with programmable logic control (PLC) and a stable safety dual valve for precise operation, automation compatibility, and fail-safe protection.
7. Wet Clutch & Hydraulic Overload Protection
Wet clutch ensures smooth engagement, while the hydraulic overload protector automatically disables operation in case of excessive force, safeguarding both machine and dies.
8. CE Ceritified & Global Compliance 
Meets stringent CE safety standards and is designed to comply with international regulations of risk-free operation in diverse markets.

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.
8. Center auto grease lubrication system is standard equipped and the lubrication frequency can be setted with the touchscreen. In the meanwhile, manual thin oil lubrication system is equipped too.
