Silicon steel mechanical scoring machine

Abstract

The invention relates to a silicon steel mechanical scoring machine which comprises a frame capable of moving along a guide rail, wherein a rack is arranged on the frame; in a co-directional manner, a denting roll, a press roll and support rolls are arranged on the rack; the position of the denting roll is fixed, the press roll is located right below the denting roll and can move up and down, the press roll is supported by two rows of support rolls below, the two rows of support rolls are respectively arranged along the axial direction of the press roll and form a 'pin' shape with the press roll (wherein 'pin' is a Chinese character), the two rows of support rolls are in one-to-one correspondence in the radial direction of the press roll, each pair of corresponding support rolls are arranged on a same support roll seat, each support roll seat is connected with a compressing hydraulic cylinder, and the compressing hydraulic cylinder can drive the support rolls to move up and down via the support roll seat. The scoring machine can adjust the dimensions of grooves, the machined grooves are uniform, and the production quality is steady.

Description

technical field [0001] The invention belongs to the field of iron and steel metallurgy, and relates to 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. [0003] 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, tension coating, and...

AI Technical Summary

Problems solved by technology

[0004] The existing silicon steel scoring is divided into laser scoring and mechanical scoring. At present, due to the limitation of laser power, the research on laser scoring of oriented silicon steel still stays in the process experiment research of the laboratory; the mechanical scoring equipment is still not available in China. none

Mechanical scoring generally has the following problems: 1) The grooves set by the process can be quickly realized on the surface of the grain-oriented silicon steel sheet. The groove size includes depth, width and spacing. ); 2) The working roll in direct contact with the silicon steel is a driving roll, which is prone to slipping with the silicon steel during production, which affects the processing quality
