Compression roller device for silicon steel mechanical scoring machine

Abstract

The invention relates to a compression roller device for a silicon steel mechanical scoring machine. The compression roller device comprises a compression roller and support rollers, which are same in direction, wherein the compression roller is supported by two rows of support rollers at the bottom of the compression roller; the two rows of support rollers are respectively arranged along the axial direction of the compression roller, and the two rows of support rollers and the compression roller form a shape like the Chinese character 'pin' (delta shape); the two rows of support rollers are in one-to-one correspondence in the radial direction of the compression roller; each pair of corresponding support rollers is arranged on a same support roller seat; each support roller seat is connected with a compression hydraulic cylinder; and the compression hydraulic cylinders can drive the support rollers to move up and down through the support roller seats. The compression roller device can adjust the pressure applied to silicon steel.

Description

technical field [0001] The invention belongs to the field of iron and steel metallurgy, and relates to a pressure roller device for a silicon steel mechanical scoring machine. Background technique [0002] With the rapid development of the economy, the demand for electric power is increasing. About 40% of the electric energy lost in the power transmission and distribution system is consumed in the transformer, and the iron loss and copper loss in the total loss of the transformer each account for about 50%. Therefore, it is a very important part of the whole energy saving and carbon reduction business to continuously reduce the iron loss of grain oriented silicon steel and realize high efficiency and energy saving of transformers. To reduce the iron loss of grain-oriented silicon steel sheets, methods such as increasing the degree of grain orientation, increasing the silicon content, reducing the thickness of the plate, reducing the size of secondary recrystallized grains, ...

AI Technical Summary

Problems solved by technology

The existing silicon steel scoring is divided into laser scoring and mechanical scoring. Mechanical scoring generally uses toothed rollers and pressure rollers to score silicon steel. The pressure roller device is the key part of the silicon steel mechanical scoring machine. The existing The pressure roller device generally has the following problems: it is impossible to adjust or it is difficult to adjust the pressure exerted by the pressure roller on the silicon steel (strip), which is not conducive to the adjustment of the groove size
