Band saw blade sand blasting model construction method and band saw blade sand blasting device and method

Abstract

The invention discloses a band saw blade sand blasting model construction method and a band saw blade sand blasting device and method. In the sand blasting process, according to the width of a band saw blade, the opening number of first spray guns and second spray guns, the width of the band saw blade covered by sand blasting when a single spray gun swings, the radius of the coverage range covered by sand blasting when the single spray gun is static, and the swing amplitudes of the first spray guns and the second spray guns are determined; then the movement speed of the band saw blade and the swing speed of the first spray guns and the second spray guns are determined according to the width of the band saw blade covered by sand blasting when the single spray gun swings, the radius of the coverage area covered by sand blasting when the single spray gun is static, the swing amplitude of the first spray guns and the second spray guns and a band saw blade sand blasting model; finally, a conveying mechanism, a first swing mechanism and a second swing mechanism are controlled to act according to the movement speed of the band saw blade and the swing speed of the first spray guns and the second spray guns, it is guaranteed that effective sand blasting areas generated by the first spray guns and the second spray guns completely cover the surface of the band saw blade, and the sand blasting efficiency and the sand blasting quality are improved.

Description

technical field [0001] The invention belongs to the technical field of band saw blade manufacturing and processing, and in particular relates to a method for constructing a band saw blade sand blasting model, a band saw blade sand blasting device and method. Background technique [0002] The band saw blade is a tool widely used in the field of metal cutting. There are two main aspects to improve the performance of the band saw blade product: [0003] ①Tooth tip (tooth material) [0004] The tooth tip serration is the direct position for metal cutting. High-performance special materials (tungsten carbide, inlaid diamond abrasive grains) and surface treatment technology (quenching and tempering heat treatment, coating) are used to improve the hardness, heat resistance and corrosion resistance of the tooth tip. properties such as wear and tear. [0005] ②Back (belt body) [0006] The belt body of the saw blade is used as the carrier for the reciprocating rotary motion of the...

AI Technical Summary

Problems solved by technology

[0011] The object of the present invention is to provide a sandblasting model construction method for a band saw blade, a sandblasting device and method for a band saw blade, to overcome the problem that the hard coating on the tooth part may be thinned or even completely peeled off when sandblasting the back of the saw blade. Ensure that the effective sandblasting area produced by the spray gun completely covers the surface of the band saw blade (that is, the back), and cannot adapt to the sandblasting requirements of band saw blades of different specifications
