JH21 series of open-type fixed-station presses

The machine adopts steel plate welding structure, and tempering treatment, which has strong rigidity and stable precision. The A-type machine adopts an electromagnetic speed regulating motor to regulate the speed, and the number of strokes also can be adjusted. The crankshaft is longitudinally arranged, which has compact structure; and the crankshaft is carried out with tempering and grinding treatment, which has smooth finish and flexible rotation.  The slider adopts six-side rectangular guide rail, which has high guide accuracy. Pneumatic double balancing cylinder can balance the weight of slider and upper die, reduce the impact and noise, and eliminate the gap between the connecting rod and slider. The whole machine is centrally controlled by imported PLC, and the gas circuit is controlled by imported safe double valve, which can realize point movement, inch movement, single and continuous punching, has sensitive action, is safe and reliable.An imported dry pneumatic friction clutch is adopted, the overload protection device or collapse protector, automatic lubrication and frequency control, etc. can be optionally equipped according to the user requirements.
