The whole structure: 1. Steel plate welded structure, hydraulic transmission, accumulator return, holistic processed, vibrating to eliminate stress, high strength and good rigidity. 2. Mechanical torque system makes sure the synchronization of cylinders. 3. The stroke of slider and back gauge is adjusted automatically by double servo motors or transducer, and showed on CNC Mechanical torque or NC control panel. 4. Slanting wedges can be chosen to install on the top dies which can be adjusted by hands or automatically. Hydraulic compensation system is installed under the worktable.
1. Hydraulic control system by BOSCH-REXROTH Germany or FIRST America. 2. Oil seals by Japanese, NOK. 3. Overload & overflow protection to ensure there is no leakage and protect hydraulic system, and the oil level can be read directly.
Servo motorized back gauge: 1.CNC Back gauge system with X axis by AC servo motor driven ball screw shafts and on linear bearings 2. Back gauge has well enough mechanical strength and rigidity with tank-type gauge structure. 3. High-precision ball screw and linear guide-way. Particular finger-stop design, enlarge the range of back gauge.
Electrical parts and protection device: 1. Schneider or Siemens Low-voltage apparatus. In accordance with international standards, reliable safety, long life,good anti-interference ability, a radiation unit is fitted in electrical cabinet. 2. Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate. 3. Light screen protection or Laser protection are optional.
