Problems solved by technology

Due to the high spot welding temperature, the microstructure and grain size of the spot welding area and the matrix are inconsistent, and the secondary tempering cannot be improved, so it will cause uneven hardness, which will affect the working state and life of the subsequent saw blade

Embodiment Construction

[0036] According to the manufacturing method described in the present invention, 3 batches of composite diamond saw blade substrates were trial-produced. The grades and specifications of the steel plates used in the substrate, and the size requirements of the substrate are shown in Table 1. Then carry out the configuration of the single saw blade base, according to the size specifications of the three batches of saw blade bases, blanking, punching, rounding and punching are carried out, and the two sides are coarsely ground, and then the saw blade base is combined. The damping material is clamped between the grinding surfaces of the equipped saw blade base. After clamping, the combined saw blade base is spot-welded for two circles along the circumferential direction, with several welding points per circle, and it becomes a composite diamond saw blade base. billet. Afterwards, quenching and tempering treatment is carried out. The quenching and tempering parameters are shown in...

Abstract

The present invention belongs to the field of cutting tool, and relates to cutting tool for stone material, cement, glass and ceramic product. The production process of composite diamond saw blade substrate includes the technological steps of: preparing two single saw blade substrates, combined dot welding, quenching and tempering, finish machining, secondary tempering and finishing grinding to form the composite diamond saw blade substrate product. The present invention has the advantages of homogeneous hardness, high production efficiency and less crack forming possibility of the composite substrate.

Description

technical field [0001] The invention belongs to the field of cutting tools, and mainly relates to the manufacture of cutting tools for stone, cement, glass and ceramic products. Background technique [0002] With the development of the construction industry, marble, granite stone, cement, glass, ceramic products, etc. have been widely used in buildings and various public facilities. At the same time, diamond saw blades are also widely used as cutting tools in the field of non-metallic hard and brittle building materials such as stone and cement products. [0003] The diamond saw blade is composed of two parts: a diamond segment and a saw blade base, which can be joined by sintering, high-frequency welding and laser welding. [0004] When the single-piece diamond saw blade is working, due to the severe impact and friction between the diamond blade and the workpiece, it will generate a lot of noise. Severe noise pollution, while damaging the health of the staff. In order to...
