Product Description

Four-column hydraulic press machine adopts three beams and four columns structure, the hydraulic system adopts cartridge valve oil circuit, the electrical system adopts relay or PLC control circuit, with adjustment and semi-automatic operation mode, the whole machine structure is simple, compact, economic and reasonable, reliable action, long service life, small hydraulic impact, reduce the connection pipeline and leakage.

  • We have designed the Single-Column Hydraulic Press with different power ranges, from 25to 400 tonnes.
  • Specifically designed to perform work involving deep-drawing, stamping, die-cutting, forming, etc.
  • The latest generation series hydraulic presses now feature a wide range of uses including the possibility of incorporating these machines in automatic production lines.

Standard Equipment

  • Mitsubishi-Japan
  • Electrics : Germany Schneider Electric
  • Main Motor:Siemens Motor-Germany
  • Foot Switch:KACON-South Korea
  • Hydraulic System:Bosch Rexroth-Germany
  • Oil Pump :Sunny-USA
  • Sealing Ring :PARKER-America
  • High efficiency motor – class IE3

Stress Analysis & Finite Element Analysis

  • The CAE software SOLIDWORKS used as the method to analyze the linear static construction, stress and deformation for press break and laser cutting machine frames. So for complicated structures, highly complex loading’s, transient modelling and combination of the above, FEA makes sense.

FEATURES

  • Steel welded body, tempering treatment or VSR(Vibratory Stress Relief), high rigidity, accuracy and stability.
  • Pneumatic dual balance cylinders, which balance the slide and punch weight to reduce noise and impact.
  • The crankshaft undergoes gringding treatment after high frequency quenching.
  • Lengthened six-face rectangle guide with a surface of bronze plate.
  • Vertical located crankshaft, compact structure.
  • PLC control and imported safety duplex valve.
  • Wet type combined multi discs friction clutch and brake.
  • Hydraulic onerload protected.

Applications

  • Auto parts: automobile body covering parts, braking, fuel tanks, chassis, axle case, bumper
  • Household appliance: washing machine, TV, refrigerator, air conditioning, rice cooker and other parts
  • Kitchenware: sink, tea set and Other kinds of containers
