Abstract

The invention discloses a process method for producing a tool through a caulking groove substrate. The process method comprises the following steps of (1) substrate preparing, (2) substrate cleaning,(3) high-speed steel bar embedding, (4) vacuum welding, (5) tempering, (6) straightening, (7) accurate grinding, (8) blade planing, (9) long blank cutting, (10) blade accurate grinding, (11) tool cutting, (12), perforating, (13), straightening and (14) cleaning, rust prevention and finished product packaging. By means of the process, the machining steps and process are shortened, the machining difficulty is reduced, the machining efficiency is improved, the machining cost is saved, and the machining yield and the stability of quality and performance are improved.

Description

technical field [0001] The invention relates to a cutting tool processing method, in particular to a method for producing a cutting tool by using an embedded groove substrate. Background technique [0002] During tool processing, the cutting edge has high hardness. Generally, a slot table is made on the steel substrate of the cutter body, and high-speed steel bars are laid and welded on the slot table. [0003] The specific process of the above-mentioned tool processing includes the following steps: blanking - punching - straight blank - planing table - cleaning - welding - tempering (multiple tempering according to needs, generally 2-3 times) - straightening - grinding Face - milling one side - fine grinding width - fine grinding length - planer edge - straightening - fine grinding edge - cleaning, rust prevention, finished product packaging. [0004] Above-mentioned processing has the following technical problems: [0005] (1) In the tool processing process, the raw mate...

AI Technical Summary

Problems solved by technology

[0005] (1) In the process of tool processing, the raw materials are cut into blanks one by one for processing. Each blank is an independent product to be processed. The processing is cumbersome, the efficiency is difficult to improve, and the production cost is high.

[0006] (2) There are many tool processing steps, and the stability and uniformity of the tool performance are inconsistent during the processing process. Different operators and different equipment will have differences. At the same time, there will be a reject rate during the processing process. The main factors that affect the quality are the welding process, especially for tools with larger cross-sections. Due to the amount of solder used during the welding process, the quality of the solder itself, the stability of the substrate and high-speed steel bars during the welding process, etc. The result of welding is affected by

[0007] (3) The post-welding treatment process is performed on the welded blanks one by one. There are also problems such as cumbersome processing, difficulty in improving production costs, and high production costs. The tool quality, performance stability, and uniformity are not consistent. The problem

[0008] (4) The problem of high inventory, large capital occupation, and high cost: agricultural knives, the thickness and width are the same, the difference is the length of the knives and the fixing holes set by the knives. Originally, it was necessary to reserve stocks for different major customers, 1000 The inventory of more than 10,000 yuan is difficult to meet the supply requirements of different customers, but now the inventory of more than 2 million yuan can easily meet the needs of various customers, greatly reducing the inventory, reducing the pressure of capital occupation, and reducing the production cost of enterprises
