Abstract

The invention discloses a method for processing a helical gear sleeve of a lower-geared roller mechanical scoring machine, which belongs to the technical field of oriented silicon steel production equipment; provides a scoring roller used for scoring the surface of oriented silicon steel; the technical proposal is as follows: a. The invention discloses a helical tooth sleeve used for a lower gear roller mechanical scoring machine. The helical gear sleeve is a tubular structure with two ends open. The inner tube wall of the helical gear sleeve is provided with a strip-shaped protrusion along the center line. The outer tube wall of the helical tooth sleeve is provided with annular teeth, the outer ring of the annular teeth is an annular edge, and the angle between two adjacent edge faces of the annular edge is 90°, so The included angle between the annular teeth and the end surfaces on both sides of the helical gear sleeve is 8°; the present invention can be widely used in the field of oriented silicon steel manufacturing.

Description

technical field [0001] The invention discloses a method for processing a helical gear sleeve of a lower tooth roller mechanical scoring machine, belonging to the technical field of oriented silicon steel production equipment. Background technique [0002] Grain-oriented silicon steel is a ferrosilicon alloy whose grains are preferentially oriented through deformation and recrystallization annealing. Its silicon content is about 3% and its carbon content is very low. The products are cold rolled sheets or strips with nominal thicknesses of 0.18, 0.23, 0.28, 0.30 and 0.35mm. This soft magnetic material is mainly used in the manufacture of various transformers, fluorescent lamp ballasts and turbo generator stator cores. When oriented silicon steel is used as a magnetic medium and is magnetized in an alternating current working environment, part of the energy will be converted into heat and lost during the electromagnetic conversion process. This part of the lost energy is call...

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 lacking in China. mature product

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
