Composed devices    

 

1. decoiler

 

supporting steel rolls and uncoiling.

 

the core can ensure the expand range φ510 of the coils inner diameter

 

It adopts the hydraulic oil cylinder to make the decoiler expandable and fit to the inner diameter of coils. It is equipped with the cantilever .

 

can do forward and reverse running as well as do the decoiling with tension.

 

 

2. straightening machine

 

    It is controlled by servo electromotor and used to regulate for high speed feed and precise length control 

 

    The operation is done at the control table with programmable control.

 

    Drive model:15kw servo motor with precise decelerating transmission and synchronous to transport the belt to feed rollers

 

 

  3.cutter

 

shear model: cut from up to down hydraulically which is cooperate with the signal direct from the feeder and shear automatically

 

Adopt gap adjusting design to cut the materials and can shear 3mm steel plate safely after heat treatment

 

 

4. hydraulic system                             

 

  Ensure the using of every hydraulic parts

 

   6.3-16Mp The working pressure of the hydraulic system is 6.3-16Mpa

 

 

  5. electrical system

 

  Adopt the PLC control mode ,It is controlled by LCD screen with fixed-length cutting by codes and count automatically .
