Metal cut to length machine

Fully Automatic High-precision Cut to Length Line

Fully Automatic High-precision Cut to Length Line

Product Description:

Fully Automatic High-precision Cut to Length Line is used to make the steel coil straighten and cut to length.

Technical Specifications:

Technological process:

Coil car-----uncoiling---straightening ----shearing machine-----stacking and piling system

1. Hydraulic entry car

Function:  It is used to lift up and down, move forward and back to make it easy to load the coils on decoiler. Hydraulic controls lifting, motor drives moving. The car is controlled on the auxiliary control panel. When the coils on decoiler, the car will return back to the start position. It can also carry back the unfinished coils from decoiler.

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

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

3) .It sets one hydraulic lifting oil cylinder, four balance guide pillars.

2. Hydraulic decoiler

Mechanical structure: the process is welded by steel plate and steel.

1).Supporting steel rolls and uncoiling, the expand and shrink plant thicken to 20mm.

2).the coil can ensure the expand range φ480-520 of the coils inner diameter.

3).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 .The coil weight can be up to 5T.

4).4KW motor drive the coils running and can do forward and reverse running as well as do the decoiling with tension.

3.Four fold leveling machine  (55KW AC)   

It is composed of 19 working rollers, driving device, 2 pinch code rollers, 3 groups of supporting rollers and machine frame. Both sides of each rolling wheel is transmitted by needle pins, all are main driving rollers. Total it is 21 rollers ,the diameter of leveling roller is 65 mm, and the distance of leveling roller is 70mm,it is with supporting rollers.

1).It makes uneven steels even and guide them to the right following process.

2).The feed part is equipped with the press and pinch device ,it drive by hydraulic.

3).Drive model: all the independent rollers and gear box are driven by 55kw frequency control electromotor machine.

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, the hydraulic cylinder lift the bridges to pass the steel sheets. when working , the bridges will lift down , the steel will be stored in the pit. There is equipped with the photoelectricity devices to adjust the high or low speed to make sure the certain store quantity in pit.

1).The pit is equipped with 2 groups of magic eyes to control the speed buffer between decoiler and slitter.

2).Magic eye is controlled by PLC.

5.Servo precision straightening machine  

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

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

3).Drive model: 11kw servo motor with precise decelerating transmission and synchronous to transport the belt to feed rollers.

6. Cutter

Function: it can accurate shear coordinated with whole line control, and With the servo feeding and the cutting settings, it can achieve seamless cooperation with the shearing time, and achive the purpose of high-speed shearing.

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

2).Adopt gap adjusting design to cut the materials

3).Four-side cutter , the material is 6CrW2Si,and it can shear 3mm steel plate safely after heat treatment.

7. Transportation table 

 Function overview: It can convey the finished sheets material to the receiving device. Because of the difference in the length of the plate material, it can adjust the speed of the transportation table according to the situation of the shear.

1).Transportation belt: It is High tension fiber conveyor belt,It is skidproof and wearable

2).Drive: cooperate with the line speed and is transmitted by 4KW frequency control motor

3).Mechanical structure: steel plate and steel welding

8.Hydraulic lifting table

 Function：It can control the lifting table up and down automatically to put the sheets, and it set track output, and convey the neat sheets by motor。

1).The length of plates can range from 500-4000mm( which can be customized)

2). The width can be ranged from 500 to 1250mm

3).Receivable frame: Hydraulic control automatic lifting.

9.Pneumatic stacker device

1).The plates are piled pneumatically and PLC controls the lifting.

2).Three 0.75kw motors drag to adjust the width and the length.

3).It is equipped with the wind device which cooperate with the high pressure fan to prevent the sheets from friction.
