J23，J21，J21S series open type inclinable press widely used stamping precision electronics, communications, computer, household appliances, auto parts, motor stator and rotor and other small precision parts. Standard J23 series double column inclinable press work load big, strong shock resistance, stable and reliable work, single stamping, continuous punching adjusted optionally. J23-80 the above products are configured lifting balance cylinder, slider, balance of the upper die of its own weight, which can prevent the reverse force transmission system caused by the phenomena before, makes the movement is very stable, can avoid and eliminate the gap of the connecting rod and the slide block, and reduce the stress impact wear parts, prolong the service life of parts due to the crash, can prevent brake failure or connecting rod fracture when the slider, effectively protect the damage and machine safety. The use of special cast iron alloy integration, high rigidity and shock resistance. The slider to a long way type design, equipped with a sliding block balancing device, ensure the operation precision and stability. All wear resistant components are electronic timing automatic lubrication system, such as the lack of lubrication oil, punching machine will stop automatically. Control system is advanced, simple, ensure the accuracy of slide operation and to stop. Can be used with any of the automated production demands, improve production efficiency and reduce production cost. Center of gravity balance 1 transmission center and the whole machine tends to be consistent, ensure the stamping precision, stability. 2 the machine adopts two slide balancer, ensure that the machine balance operation. Reliable operation, safety clutch / brake device for highly sensitive, plus the top double electromagnetic device and overload protection device, ensure the accuracy and safety of the press slide operation and to stop. The slide block adjusting mechanism adjustment precision up to 0.1mm, adjust the production safer, faster. High precision of crankshaft, gear, gear shaft friction and other parts of the stable were treated by hardening heat treatment after grinding, abrasion resistance and balance of high and stable performance. Processing automation, labor saving can be used with any of the automatic feeding mechanism, automated production, reduce costs, improve efficiency. Environmental protection advanced design, low noise, low consumption, energy saving.
