4×1600 Steel Coil Rotary Shear Cut to Length Line Machine Metal Leveling and Cutting Machine

Cut-to-length lines with high-accuracy and high-speed
The Cut-to length lines have been proved quite successful with high-accuracy and cost -effective mainly due to the appropriate configurations such as:servo positioning svstem PLC User-friendly HMI,automated shearing and stacking,etc.

The slitter line consist decoiler,slitting machine and winder. Unit control adopts hydraulic system. It is featured in fine automatization, accurate slicing, orderly coiled material and complete types.

1. Hydraulic entry coil car
The car can move levelly and vertically, which is convenient for putting the steel coils into the de-coiler.
It is driven vertically by hydraulic cylinder with four guide pillars.
The level movement is driven by cycloid motor.
The capacity it can carry is 10 Tons(Max).

2. Hydraulic cantilever de-coiler
Supporting the coils and doing uncoiling. The capacity is 10Tons(max).
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.
The core can ensure the expand range φ508 of the coils inner diameter.
Structure: welding by the steel plates and profiled bar.

3. 4-h 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 15, the diameter is 65and the distance between the rollers is 70mm, with supporting rollers. All the rollers are plating leather to protect the stainless steel plate surface is not wear.
The function of the supporting roller is to balance the leveling rollers force and reduce the friction to the rollers.
Driving model: all the independent rollers and gear box are driven by 30Kw frequency control motor

4. 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 leadscrew. The range of the width is 500-1400mm.

5. 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.
Drive model:15Kw servo motor with precise decelerating transmission and synchronous to transport the belt to feed rollers

6. 1400 Hydraulic 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

7. Transportation table
Transportation belt is skidproof and wearable
Drive: cooperate with the line speed and is transmitted by 2.2KW frequency control motor

8. Hydraulic lifting table
The length of plates can be 6m
The width cab be ranged from 500 to 1400mm.

9. Pneumatic stacker device
The plates are piled pneumatically and PLC controls the lifting.
Three 0.75kw motors drag to adjust the width and the length.
It is equipped with the wind device which cooperate with the high pressure fan to prevent the sheets from friction.

10. Pneumatic system
The pneumatic system is composed of the air power(prepared by the buyer), air source treatment components , salennoid, relevant pipeline and air cylinder, etc. The components such as salennoids are adopted high quality products.
Technical parameters: stress of air source: 0.4-0.6Mpa. The capacity:1m³ /min.

11. Hydraulic system
Ensure the using of every hydraulic part.
The working pressure of the hydraulic system is 6.3-16Mpa.

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