Hydraulic overload protector has sensitive response and reliable motion, which can protect the die when overloading.

Features:                                                             

Universal high performance presses are widely used in the fields of aeronautics,auto,agriculture machines,electric machines,apparatuses and meters,medical equipments,electrical home appliance and hardware.                                                                      1.  Welded frame with quality steel which means good rigidity.                       2.  Square figure long guide with six friction faces makes abrasion resistant and punching precision.                                                                    3.  Hydraulic overload protector has sensitive response and reliable motion, which can protect the die when overloading                                                                    4.  Combined pneumatic clutch and brake are made of friction material, which means long service life.                                                                5.  Closed gear-driven, dipped in lube, which drives stably with low noise.    6.  Slide with counter balancer, which will eliminate the clearance and improve the stability and precision.                                                                    7.  Intermittent auto lubrication makes every point get fine and safe lubrication. Thus, long service life is saved.                                                                  8.  PLC electric control system is safe and reliable                                                      9.  Air cushion, photo guard, auto feeder ,speed die changing and variable-speed device are optional.
