Problems solved by technology

[0004] However, at present, the main form of laser welding bimetallic band saw blades is the welding of spring steel strips and high-speed steel strips, because cemented carbide is formed by powder sintering and cannot be made into strips for continuous laser welding
In addition, in the butt welding positioning of the back material and the tooth tip block, due to the processing error of the back material tooth pitch and other issues, welding misalignment will occur. If the two materials are not positioned correctly, the quality of the weld will be deteriorated. If it is lowered, it will cause problems such as saw teeth falling off on the bimetallic saw blade, which will affect the service life of the saw blade

Abstract

The application discloses a bimetallic band saw blade welding device and method, wherein the welding device includes: a welding assembly, the welding assembly includes a laser head body; The back material moves a preset distance, and the starting point of the welding line to the back material is aligned with the center of the laser head in the Z-axis direction; the back material positioning component is used to compress and position the back material; the electromagnetic clamp The component is used to obtain the tooth tip block and drive the tooth tip block to move to a position corresponding to the tooth holder of the back material; the back material support table is used to place the back material. The bimetallic band saw blade welding device provided by the application can accurately position the tooth tip block and the back material and carry out continuous automatic welding, and has a simple structure and low welding cost.

Description

technical field [0001] The present application relates to the field of bimetal band saw blade welding, in particular to a bimetal band saw blade welding device and method. Background technique [0002] Bimetallic band saw blades are made by welding tooth tip blocks made of high-speed steel or other high-performance steel and spring steel strips together, then shaping the saw teeth, and finally improving the properties of the material through quenching and tempering. Metal cutting band saw blade. The use of dissimilar metal welding can not only save rare metals, reduce production costs, but also meet the use requirements of parts. The tip material of the bimetal band saw blade is high-performance material such as high-speed steel or hard alloy, which has the characteristics of high hardness, good wear resistance, and strong red hardness. The back material is spring steel, which has high strength, good toughness, and fatigue resistance. Excellent performance characteristics....
