Equipment peculiarities

 

  • Single / double chain drive.
  • Components of the machine (chains, clamps, rollers and bearings) made of high-strength high-carbon steel FC25.
  • Coolant system provides long service life of drawing sizing mill parts.
  • Pneumatic clamps provide a secure fit of the drawing mill chains.
  • The ability to adjust the speed of reverse movements to reduce the time for the next load to minimum.
  • Reinforcing rod unloader is controlled by pneumatic valves.
  • Die holder is equipped with a ball joint.
  • Swaging mechanism is applied before the process of cold drawing for crimping the head of the blank for the convenience of its subsequent passage through the components of the production line. In addition, the form of crimped part can be designed on request.

SWAGING MACHINE

Drawing sizer can be additionally equipped with a swaging machine. This equipment is used to the cold drawing process for crimping the head of the blanks for the convenience of its subsequent passage through the components of the calibration line. Crimped part shape can be designed according to the customer requirements. Swaging machine is suitable for pre-calibration of a wide variety of products such as metal pipes, tubes, wires, rods of wrong size, including the penpoints, umbrellas, glasses, bicycle frames.
