Longitudinal shear coil slitting machine is mainly used in the use of silicon steel sheet, aluminum coil, galvanized coil, stainless steel, plain carbon steel and other coils and strips of sheet material along the length of the slitting into a number of small strips. Longitudinal shear metal slitting machine to some extent also known as longitudinal shear, slitting machine, rolling shear, disc shear, slitting machine.
Function description: Slitting and steel slitting machine is used to slit silicon steel sheet, aluminum coil, galvanized coil, stainless steel, plain carbon steel and other coil sheet into several small strips along the length direction. The longitudinal shear slitting machine consists of upper and lower knife shafts and fixed, synchronized lifting structure. The plaque is cast, aging treatment, boring machine precision machining. The upper and lower cutter shafts are finely processed through many processes, such as turning, high-frequency treatment, grinding, chrome-plating and then grinding.
So what are the factors affecting the slitting size during the operation of the slitting machine?
1. In the operation process of the slitting machine equipment, if there is a problem of transverse oscillation of the tool, then it will lead to the generation of poor dimensions, such as the transverse oscillation of the tool and the outer diameter of the tool size is different and poor. As the value of transverse oscillation of the tool cannot be zero. The reason is the accuracy error of the tool thickness, inner diameter, spacer sleeve width, etc., and the warping produced by the lateral stress during the shearing of thick plates.
2. During the production of the steel slitting machine equipment, there was a problem of transverse warpage of the steel plate, which resulted in poor width dimensions. This is due to the fact that the measurement of the product cut in the state of transverse warpage is larger than the setting value of the cutter.
3.Due to the production operation of the slitting machine equipment, there is a certain matching error in the spacer set and knives. The cumulative error becomes larger when the number of pieces is larger when the knife is matched. This is due to the poor setting of the upper tolerance. It is important to know that the width of the product cut by the slitting machine is always slightly lower than the product side dimensions of the knife.
Therefore, it is necessary to anticipate the extent of this difference in advance. This is referred to when determining the dimensions of the product side of the knife time spacer. The shearing method used is also taken into account. In comparison, if the slitting machine equipment adopts the straight pull type shear, then the tension of the steel coil is increased, the transverse warpage will disappear, and the size will also go down the difference.
