Automatic longitudinal shearing and cutting machining equipment and method for silicon steel sheets

Abstract

The invention relates to automatic longitudinal shearing and cutting machining equipment and method for silicon steel sheets. The automatic longitudinal shearing and cutting machining equipment comprises fixing frames, unwinding drums, longitudinal shearing devices and cutting devices, wherein the lower ends of the fixing frames are connected with the existing ground, and the fixing frames are symmetrically distributed front and back; the unwinding drums are rotationally connected between the front and back opposite fixing frames; and the longitudinal shearing devices and the cutting devices are sequentially arranged on the right sides of the unwinding drums from left to right. According to the automatic longitudinal shearing and cutting machining equipment, a motor, rotating shafts and rotating rods do synchronous high-speed rotating motion, the rotating rods drive cutting knives to do synchronous high-speed rotating motion, and therefore the function that the cutting knives longitudinally shear silicon steel coils can be achieved; and the wider silicon steel coils are divided into two parts to form narrower silicon steel coils, so that the subsequent further processing speed of silicon steel is improved.

Description

technical field [0001] The invention relates to the technical field of silicon steel, in particular to an automatic slitting and cutting processing equipment and a processing method of a silicon steel sheet. Background technique [0002] Silicon steel is a silicon alloy steel with a silicon content of 1.0-4.5% and a carbon content of less than 0.08%. It has the characteristics of high magnetic permeability, low coercive force, and large resistivity. A certain degree of plasticity is required. In order to improve the magnetic induction performance and reduce the hysteresis loss, the harmful impurity content is required to be as low as possible, and the plate shape is required to be flat and the surface quality is good; and the silicon steel sheet is a kind of ferrosilicon with extremely low carbon content. Soft magnetic alloys generally contain 0.5-4.5% silicon. Adding silicon can increase the resistivity and maximum magnetic permeability of iron, reduce coercive force, core ...

AI Technical Summary

Problems solved by technology

[0003] 1. The large width of the silicon steel coil makes it difficult for the cutting knife to cut it off at one time during the process of cutting it into pieces, resulting in low processing efficiency;

[0004] 2. In the process of cutting silicon steel to fixed length with existing equipment, silicon steel is prone to deformation, and the cuts are uneven, which affects the quality of finished silicon steel
