FRICTION SCREW PRESS

Birson Industries

Birson Industries offers Friction Screw Press (Down Stroke). These Friction Screw presses are preferred for hot forming (Forgings) and cold coining. Stamping, embossing, Sizing nonferrous metals. The press body is steel welded construction one piece box type design. After the welding the press body is glowed free from tension. The Screw is made of high quality alloy Steel and is heat treated to have great hardness at the same time great elasticity. Fly wheel screw presses machines of this type are characterized by the fact that fly wheel connected to accelerated at the start of working stroke, then braked to a standstill by the actual forming process. Thus the entire kinetic energy stored in the fly wheel released screw press have not kinetically fixed bottom dead center point in common with drop forging itself or by stops in the tool in turn, this results in advantage tool height adjustment is eliminated, forging accuracy is greater. In addition Digital indicator meter is provided to measure speed of ram, numbers of stroke count & impact force in tons of press is transfer to P.C. Slipping clutch wheel overload protection pneumatic control can be provided.

Features and Advantages

  • High useful working energy
  • Mechanical energy store
  • Overload protection by slipping wheel
  • Thermally stable ram guide ways with wear-proof guide gibs
  • High forging precision
  • No need to readjust ram with machine warming up
  • No jamming under load possible
  • Long Die life because of short Pressure-Contact Times
  • Sequence of different strokes on one work piece possible
  • Totally closed die forging capability
