JH21 series model D press

D JH21 series steel welding machine, good rigidity, precision stability, The crankshaft, compact structure, longitudinal appearance, The crankshaft parts with stroke adjusting device. Through the adjustment of this device can change the slider, which satisfies different process needs. Using dry-method composite pneumatic friction clutch brake, smooth, action quick, joints, low noise. Gear oil lubrication; deputy leaching Using rectangular slide guide rails, six lengthen face panels, orientation of copper in high precision, slider setting has imported hydraulic overloading insurance device (imported pneumatic pumps, inlet high-pressure oil). After the overload automatic reset, and sensitive unreliable. JH21-63D above electric loading mode, JH21 height adjustment slider 45D - above installed in type cylinder (balance), adopts imported seal with electric, pneumatic lubricating system for imported safety valve control, electric imported brand PLC control, high safety. Optional air device, automatic feeding shaft device, photoelectric device, can match various automation equipment, load punch safety standards.
