Base plate for cutter machining

Abstract

The invention discloses a base plate for cutter machining. The base plate comprises a base plate main body, an embedding groove is formed in the upper surface of the base plate main body, the embedding groove is used for fixing a high-speed steel bar, a cutting and edge-planing groove is formed in the lower surface of the base plate main body, and the cutting and edge-planing groove is formed under the embedding groove. According to the base plate, in the welding process, the welding quality can be improved, cutting and edge-planing are convenient after welding, so that the cutting and edge-planing efficiency is improved, and consumption on labor, equipment and electric energy in the production process is reduced; and meanwhile, generation of waste materials in the cutting and edge-planingprocess is greatly reduced, the utilization rate of steel materials is effectively improved, and the base plate has very good economic benefit and social benefit.

Description

technical field [0001] The invention relates to cutting tool processing, specifically a substrate for cutting tool processing. Background technique [0002] During tool processing, the hardness of the cutting edge is high. Generally, a slot table is made on the main body of the steel material of the knife 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 materials are cut into blanks on...

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 main body of the substrate and the high-speed steel bar during the welding process, etc. have an effect on the welding results

[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) Large inventory, slow turnover, large capital occupation, and high cost. Agricultural knives, such as household harvesters and pulverizers produced by different manufacturers, have the same thickness and width of the knives, and the length of the knives is the same. , The design of the fixing hole and groove of the tool is different; in order to supply the tool to different manufacturers in time, it is necessary to maintain a certain inventory. Because the length of the tool and the setting of the fixing hole of the tool are different, generally different manufacturers prepare stocks separately, and the total inventory is equal to very big

[0012] (1) The thickness of the main body of the substrate and the high-speed steel bar after welding is the same as that of the main body of the substrate. In the subsequent processing process, the entire thickness needs to be planed and cut, and the efficiency is not high enough;

[0013] (2) During the subsequent processing, planing and cutting require a lot of labor, electric energy and planing and cutting parts of equipment, which increases the economic cost

[0014] (3) When planing and cutting, a large amount of waste chips are generated, the raw materials are not fully and effectively used, and steel materials are wasted
