 Composed devices         

1.hydraulic entry car                           

   ◆The car can move levelly and vertically, which is convenient for putting the steel coils to the un-coiler.

   ◆It is driven vertically by hydraulic pressure and the level movement is driven by  cycloid electromotor .

2. Cantilever 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 .

   ◆40N.m moment motor drive the coils running and can do forward and reverse running as well as do the decoiling with tension.

3. fourfold pre-leveling machine

   ◆It is equipped with the press and pinch device at the entry which is driven by hydraulic.

   ◆It is composed of 17 leveling rollers, 2 groups of supporting rollers ,driving device and 2 pinch rollers and frame. Both sides of each rolling wheel is transmitted by needle pins all are the main force rollers.the total quantity of the rollers is 19, the diameter is 60and the distance between the rollers is 65mm, with supporting rollers.

   ◆The function of the supporting roller is to balance the leveling rollers force and reduce the friction to the rollers.

   ◆The working rollers can be adjusted the gap electrically which is controlled by 2 hand wheel to ensure the leveling quality.

   ◆Driving model: all  the independent rollers and gear box are driven by 22kw frequency control motor

4. Loop

       Function : it is used to eliminate the different speed and make the plates which in wrong rail to back the right way. At first, it is used the oil cylinder to lifting the supporting and transition plates to make the head pass . when working , the transition and supporting plates lift down , the steel plates will be stored in the pit.  

5. side guide device

   ◆It uses the vertical roller-wheel on the both sides to direct strips into straightening device and cutting machine.

   ◆The stand rollers on both sides are adjusted by lead screw. The range of the width is 300-750mm

6. servo precision 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
