Cut To Length Machine
cut to length process is used for uncoiling, straightening, gauging, cross-cutting to length and stacking work. The cut to length line can make sure of accurate feeding and shearing. Cut to length machine is controlled by PLC system or manually as required by the customer. It has PLC controlled single shaft feeder, the information of length, shearing numbers and speed. When the needed shearing number is reached the line can stop automatically. The line speed can be adjusted. It has a gauge with high precision, and the whole line can work automatically and operate easily thereby producing smooth sheets.

Layout of Cut to Length Line Machine
Brief Introduction of The Cut To Length
Automatic cut to length line, it is used to make the steel coil straighten and cut to determined length.
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 a cycloid electromotor.
- It sets one hydraulic lifting oil cylinder, four balance guide pillars
- 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.
2) Hydraulic decoiler
- Supporting steel rolls and uncoiling, the expand and shrink plant thicken to 20mm.
- the coil can ensure the expanding range φ480-520 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.T he coils weight can be up to 20T
- A 4KW motor drives the coils running and can do forward and reverse running as well as do the decoiling with tension.
- Mechanical structure: the process is welded by steel plate and steel.
3) Fourfold pre-leveling machine
- It makes uneven steels even and guide them to the right following process
- The feed part is equipped with the press and pinch device, it drives by hydraulic
- It is composed of 17 working rollers, a driving device, 2 pinch code rollers, 2 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 19 rollers ,the diameter of leveling roller is 65mm,and the distance of leveling roller is 70mm,it is with supporting rollers
- the function of supporting roller: make the even rollers receive the balanced force and reduce the friction of the leveling rollers
- the working rollers use electric machine to adjust the upper and lower gap with 2 hand wheel to make sure the even quality.
- Drive model: all the independent rollers and gearbox are driven by 45kw frequency control electromotor machine.
- Automatic circulating lubrication system
- Main parameter
|Work roller material||GCr15||forge piece|
|Work roller surface hardness||HRC55-60||3-5mm Hardened depth 3-5mm|
|Supporting roller material||42Cr||forge piece|
|surface hardness of supporting roller material||HRC52-56||Hardened depth 3-5mm|
|Roller handling process||Raw material tempering－rough process－Hardened HRC55-60－finish machining||According to the bearing shaft processing technology|
- The pit is equipped with 2 groups of magic eyes to control the speed buffer between decoiler and slitter
- Magic eye is controlled by PLC
- Function: it is used to eliminate the different speed and make the plates which in the wrong rail to back the right way. At first, the hydraulic cylinder lifts 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 a pit.
5) Side guide device
- It uses the vertical rollers of both sides to guide the plates into the slitting machine correctly.
- The guide rollers are adjusted by the rods on both sides . The width range is 500-1500 mm.
- Main parameter
|Guide model||vertical edging roller||6pieces|
|Guide roller technology||Quench and finish grinding|
|Adjustment model||Adjustment by manual|
|Main part||Welding parts, overall aging treatment|
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 with programmable control.
- Five roller straightening system: up 2 down 3 configuration
- Roller handling process: Raw material tempering－rough process－Hardened HRC55-60－finish machining
- 4 roller pressure feeding length, all roller quenched surface coated by polyurethane and fine grinding into
- Drive model: 15kw servo motor with precise decelerating transmission and synchronous to transport the belt to feed rollers.
- shear model: cut from up to down which is cooperate with the signal direct from the feeder and shear automatically
- Pneumatic control, and automatic control the shearing
- Adopt gap adjusting the design to cut the materials
- Four-side cutter, the material is 6CrW2Si, and it can shear 3mm steel plate safely after heat treatment
- 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 achieve the purpose of high-speed shearing.
