The Function of Slitting Equipment for Slitting Shears

Slitting machine, its equipment composition, is the uncoiler, guide device, uncoiling tension device, clamping device, winding machine, disc shear, guide roller and live sleeve and so on these. And, there are specific forms of them, which are.

1. Single-entry live sleeve slitting shear: this kind of slitting shear, is set in front of the shearing bed live sleeve, and the strip is fed into. Its live sleeve method, is to have driven unwind, tension unwind and floating roll control unwind and these. In addition, it can achieve micro-tension or zero-tension shear, to avoid the shear edge slippage this phenomenon problem, at the same time, the uncoiler cannot use the alignment device, in the live sleeve to achieve alignment, can.

2. Single outlet live sleeve longitudinal shear: its difference with the single-entry live sleeve longitudinal shear, is to set the live sleeve after the shear bed. For thin strips, a guide system may be required at the material entrance to avoid the problem of unsynchronized winding. And from the present point of view, this form is used more often.

3. Slitting equipment double shear slitting shear: is a combination of the entrance shear and exit shear slitting shear of both forms, mainly used in the slitting strip, suitable for thin and soft strip shear.






Longitudinal shear slitting equipment blade use: for longitudinal shear equipment, the blade itself is actually an important part, and its use in the process of wear and tear, which is actually normal. However, slitting cases, if it is excessive wear and tear, is not normal. Therefore, in the choice of blades, should choose good quality, so that it can reduce the degree of wear and tear, and at the same time, extend the service life of the blade.

Slitting equipment knife set blade thickness size consistent, and after that will also meet the requirements of the drawings, we should also pay attention to this blade outside diameter consistent and blade parallelism, coaxially in line with the requirements of the drawings; slitting machine blade edge at no bump, drop meat, wear and other phenomena; spacer thickness size in line with the requirements of the drawings, spacer parallelism size and other requirements; other dimensions in line with the requirements of the drawings.

A series of processing operations such as uncoiling, leveling and shearing of metal sheets, referred to as longitudinal shearing and slitting equipment.
Slitting equipment classification of slitting equipment slitting equipment mainly has.　　
1. Unwinding - flattening - cross-cutting - palletizing production line
2. Unwinding - longitudinal shearing - leveling - rewinding production line
3. Unwinding - leveling - longitudinal shearing - rewinding / sizing - cross-cutting composite production line



This series of production line is used for uncoiling, leveling, sizing and shearing metal coils of different specifications into flat sheets of required length and width, suitable for processing cold rolled sheets, galvanized sheets, color coated sheets and stainless-steel sheets.

Loading trolley → uncoiler → leading device → traction leveler → transition bridge → deflection correction device → servo feeding → shearing machine → conveyor belt → drop → stacking.

The maximum running speed of this series of production line is 120m/min, and it can protect the flatness of the sheet without scar; the feeding is driven by servo motor, with high shearing accuracy; the double palletizing discharge is efficient and fast.

The main drawbacks of using felt type hydraulic tension station for slitting processing are: the size of the winding tension is difficult to adjust and difficult to control, the tension distribution between the operating side and the driving side of the steel belt is not uniform, and the lack of tension will cause the steel belt to collapse and fall apart when unloading the coil at the winder; the felt is easy to stick to the small iron chips and impurities, which will lead to the scratching of the protective film and the steel plate on the color coated steel plate of the appliance, and produce unqualified products. The protective film and steel plate are scratched, resulting in unqualified products.

Therefore, in the production process, the felt must be replaced from time to time, which greatly reduces the production efficiency and increases the production cost.

Therefore, in the longitudinal shearing and slitting processing unit, the pressure plate method is only applicable to the production of cold-rolled steel plate or stainless-steel plate with low requirements on the plate surface, but not for the production of color coated plastic steel plate for home appliances.
