Configuration
  • High-rigidity steel-plate welded frame.
  • Combined dry pneumatic friction clutch
  • Cylinder type stroke adjusting structure
  • The slide is guided by eight-sided guide, among them, JL21-25 hydraulic presses by six-sided guide.
  • Hydraulic overload protection device
  • Automatic oil circulating lubricating system. JL21-25 employs electric grease lubrication.
  • JL21-63, JL21-80, JL21-110, JL21-125, JL21-160, JL21-200, JL21-250 series stamping presses adopt electric die height adjustment with digital display.
  • Lifting counterbalance cylinder
  • Dual solenoid valve
  • Integrated control panel (electronic cam included)
  • International brand PLC control
  • International brand buttons, AC contactor, air switch
  • Option: Air cushion (airbag type or cylinder type), automatic feeding shaft, photoelectric protective device, slide knockout device, and can be matched with all kinds of automation equipment.
Features of adjustable stroke press
  • Drive gears enclosed inside the press frame, gears immersed in oil for lubrication
  • The slide is a cast box structure fitted with hydraulic overload protector acting sensitively and reliably. After overloaded it can automatically reset that can reduce downtime as well as improve the working efficiency of the press machine.
  • Employ eight-sided rectangular lengthened guide with high guide precision and good precision retaining ability.
  • Adopting Omron programmable controller (PLC) for centralized control that can effectively guarantee the reliability of the electric control parts.
  • Japanese TACO duplex safety valve is employed to ensure the safety and reliability of clutch operation.
  • Cam controller made up of Schneider switches can send out signal accurately within 360°, precisely control all action specifications of main machine as well as coordination with accessory machine, so as to improve the running reliability of the press.
