Welding equipment and welding method for bimetallic band saw strips

Abstract

The invention relates to the field of bimetallic saw strip machining, in particular to welding equipment and welding method for bimetallic band saw strips. The welding equipment comprises a laser generator, a base material supplying slide rail, a pre-welding position alignment device, a main controller, an upper fixture device and a lower fixture device, wherein the upper fixture device and the lower fixture device are symmetrically arranged up and down, the laser generator is arranged at the downstream end of the base material supplying slide rail, the upper fixture device and the lower fixture device are located above and below the base material supplying slide rail correspondingly, the back side of the base material supplying slide rail is provided with a power device, the front side and the back side of the base material supplying slide rail are each provided with one clamping device, and the pre-welding position alignment device can be movably arranged at the end portion of the downstream end of the base material supplying slide rail through an avoidance air cylinder and is further in electrical connection with the main controller. By means of the welding equipment and weldingmethod for the bimetallic band saw strips, two pre-welding base materials can be effectively clamped and positioned, and then the welding quality is improved, in addition, a rubber shaft sleeve and arubber sleeve which are in direct contact with the base materials can both be detachably arranged, and the fixture maintenance cost is greatly lowered.

Description

technical field [0001] The invention relates to the field of bimetallic saw blade processing, in particular to a welding device and a welding method for a bimetallic band saw blade. Background technique [0002] Bimetal band saw blade mainly refers to the metal cutting band saw blade whose tooth tip material is high-speed steel or other high-performance steel, and the saw band material is low-alloy spring steel. [0003] In the production and processing of bimetallic band saw blades, it needs to go through back material trimming → laser welding → bright annealing → welding seam flattening → leveling and straightening → fixed length preparation → milling teeth → splitting teeth → quenching and tempering → sandblasting → rolling Rolling and straightening → printing and antirust → coiling and packaging → fixed-length cutting tape → butt welding of the root tape → embedding of the root tape → packing of the root tape and other processes. , welded together with the substrate, wh...

AI Technical Summary

Problems solved by technology

[0004] In the side butt welding of the strip and base material, due to the inaccurate positioning of the two materials, the weld between the two base materials is not easy to meet the standard. At the same time, due to the high hardness of the strip and base material, the corresponding tooling fixtures wear, further reducing the quality of the weld seam

The reduction of weld seam quality will lead to problems that affect the life of the product, such as sawtooth shedding of bimetallic saw blades
