A method for manufacturing a composite sound-absorbing diamond saw blade matrix

Abstract

The invention provides a manufacturing method of a composite noise-reducing diamond saw blade base body. The manufacturing method comprises the process steps of: preparing a single-sheet saw blade base bodies, carrying out combined rolling welding, quenching and annealing, and carrying out finish machining. The manufacturing method is characterized in that after two single-sheet saw blade base bodies are wholly punched and baited and burrs are removed, a damping material is clamped between the two single-sheet saw blade base bodies; a composite noise-reducing diamond saw blade base body blank is formed by rolling welding and the composite noise-reducing diamond saw blade base body blank is subjected to continuous pressurizing, oil spraying and quenching, controllable temperature pressurizing, cooling and finish machining to form a composite noise-reducing diamond saw blade base body finished product. The manufacturing method disclosed by the invention has the advantages that the single work procedure efficiency in a product manufacturing process is improved and the secondary annealing do not need to be carried out, so that the machining cost of the product is effectively reduced and various performance indexes of the product are improved.

Description

technical field [0001] The invention belongs to the field of cutting tools, and relates to a method for manufacturing a composite sound-absorbing diamond saw blade matrix. Background technique [0002] The base of the compound noise-absorbing diamond saw blade is welded by two single saw blade bases and a material with better clamping damping performance in the middle. "Composite sound-absorbing saw blade base. [0003] In the existing manufacturing method of composite sound-absorbing diamond saw blade matrix, it is generally first to use the steel plate as the raw material of the saw blade matrix as the raw material for blanking, punching, rounding and rough grinding, and then equipped with a single saw blade matrix, clamping a layer The damping material is spot welded to form a composite diamond saw blade base blank, and then quenched and tempered. After the heat treatment, the saw blade base is finished, that is, fine turning, milling and fine grinding, and tempered agai...

AI Technical Summary

Problems solved by technology

[0004] In the existing manufacturing method, there are many steps to equip the base of a single saw blade, and the saw blade needs to be roughly ground to waste raw materials; the traditional spot welding is single-point welding, which has defects such as low efficiency and uneven distribution of solder joints, which directly causes the hardness of the saw blade base Quality problems such as unevenness, flatness, end jumping, and large stress value difference; traditional quenching is a free-state oil bath and pressurized for a certain period of time. After quenching and tempering, there are large flatness and stress differences in the saw blade matrix Increase the difficulty of leveling in the post-process; the processing efficiency of the tooth milling process in the finishing process is low; due to the large amount of grinding in the finishing process, the deformation of the saw blade substrate and the change of internal stress will require secondary tempering, which will prolong the processing cost of the product and Increased processing costs

The above problems in the traditional manufacturing method seriously restrict the product process quality, processing efficiency and processing cost of the composite sound-absorbing diamond saw blade substrate.
