Product Description

High precision single point open press

Pneumatic punch presses use the high-pressure gas produced by compressors to force metal into molds for wafer processing,stamping,embossing, etc.
&.Steel plates welded as machine body, treated to remove internal stress, marked with high rigidity;
&. Crankshaft longitudinally arranged, compact structure and beautiful outlook;
&. Hexagonal guide rails of extra length, guide in high precision;
&. PLC-controlled electric circuit, safety duplex valve for air pipelines, flexible and highly sensitive in movement,safe and reliable, single time, inching
and continuous operations for options, conforming to the safety standard for stamping machines;
&. Hydraulic overload protection device and rigid protection device to prevent damage of the machine tools due to overload;
&.Combined-type pneumatic friction clutch-brake, steady engagement, low noise level;
Professional stamping automation equipment
The machine body is welded of quality and treated by tension elimination, improve stability and reliability of precision of the machine. Crank, gear, connect bar are oxidized hardening and milled, having super comrehensive mechanical perfor-mance and durable function. Reasonable structural design, is convenient for au-tomatic production and line production. Used reliable high intensity clutch/brake and twin electromagnetic valve, overloading protector can guar-antee safe production all-around. Adopt safety double solenoid valve and hydraulic overload protection device to ensure production and operation safety. The mold bearing large impact loading as well as pressing of eccentric mold. Adopted closed electric loop circuit, have compatible with any automatic equipments.
