Ultra-fine particle carbide bimetallic band saw blade

Abstract

The invention relates to an ultra-fine particle cemented carbide bimetallic band saw blade, which comprises a saw blade body, a plurality of tooth tip bodies are arranged at equal intervals on the upper part of the saw blade body, a tooth tip groove is arranged in the middle of the tooth tip body, and the tooth tip There are hard alloy tooth tips welded in the slot and two adjacent hard alloy tooth tips are respectively arranged on both sides of the upper part of the saw blade body, one of which is welded to one end of the corresponding tooth tip groove, and the other is hard alloy tooth tip. The alloy tooth tip is welded to the other end of the corresponding tooth tip groove, and the outer surface of the carbide tooth tip protrudes from the outer surface of the saw blade body. The invention has the beneficial effects of being economical, greatly improving the production efficiency, reducing the cost of machining, labor and electric energy, and the tooth tip is firm, not easy to crack or drop, and has a long service life.

Description

technical field [0001] The invention relates to an ultrafine particle cemented carbide bimetallic band saw blade. Background technique [0002] At present, the saw blades used in the sawing of metal and non-metal materials in the prior art generally use various forms such as strips, strips, and discs. , although this structure has certain advantages, such as simple and convenient manufacturing and processing, it often cannot meet the needs of sawing difficult-to-machine materials. The saw with this integrated structure often deforms, blunts, and removes chips. Difficulty, skewed sawing, poor processing effect, low efficiency, and short service life. [0003] Bimetal band saw blades are widely used in machinery manufacturing, metallurgy, chemical industry, military industry and other industries because of their characteristics of high efficiency, low energy, energy saving and material saving. It is a compound sawing tool made of high-speed steel sawtooth and ultra-high-stre...

AI Technical Summary

Problems solved by technology

It is a compound sawing tool made of high-speed steel sawtooth and ultra-high-strength alloy steel substrate through vacuum electron welding, and a series of cold and hot processing processes; the existing bimetallic band saw blade has cutting ability and wear resistance This is mainly due to the fact that the selection of the existing heat treatment process parameters is determined for the tooth high-speed steel material, and the alloy steel of the saw blade base is treated with this process specification, and its fatigue resistance is greatly reduced, which leads to the use of When the wear of the teeth is very small and the performance is intact, the substrate will crack or even break, resulting in the problem that the failure of the teeth and the substrate is not synchronized, which will affect the service life of the bimetallic band saw blade and waste raw materials.
