Carpentry cutter body manufacturing process

Abstract

The invention relates to a carpentry cutter body manufacturing process comprises the steps of cutter body wax mold body pressing, gate wax mold pressing, wax mold repairing, module welding, shell manufacturing, de-waxing, mold shell roasting, cast steel smelting, casting, and shakeout. The carpentry cutter body manufacturing process provided by the invention has the advantages that: with the carpentry cutter body manufacturing process, carpentry cutter body with high hardness, high toughness, high-temperature resistance, and high cutter body casting size precision can be manufactured. Also, large amount of machine tool equipment and processing time can be saved, and also metal raw materials can be greatly saved.

Description

technical field [0001] The invention relates to the field of mechanical cutter manufacturing, in particular to a manufacturing process of a woodworking cutter body. Background technique [0002] Usually woodworking tool materials mainly include carbon tool steel, alloy tool steel, Stellite alloy, high-speed steel, etc. These materials are often used in occasions with low cutting speed, low feed speed and low processing accuracy requirements, and are generally used for solid wood processing. . But existing woodworking cutter has following shortcoming: [0003] 1. The manufacturing cost is relatively high. Since high-speed steel, cemented carbide and superhard materials are made of W, Cr, Co or PCD (synthetic polycrystalline diamond), PCBN (polycrystalline cubic boron nitride), although the manufacturing cost of high-speed steel is lower than other materials, it is difficult to process The application of high-strength woodworking composite materials is limited due to the in...

Problems solved by technology

[0003] 1. High manufacturing cost

Since high-speed steel, cemented carbide and superhard materials are made of W, Cr, Co or PCD (synthetic polycrystalline diamond), PCBN (polycrystalline cubic boron nitride), although the manufacturing cost of high-speed steel is lower than other materials, it is difficult to process The application of high-strength woodworking composite materials is limited due to the influence of processing efficiency and surface finish; although cemented carbide, PCD, and PCBN materials can meet the processing requirements of high-strength woodworking composite materials, their manufacturing process and formula determine the material cost. high

[0004] 2. There is a contradiction between wear resistance (hardness) and toughness (strength) in the selection of tool materials

[0005] 3. Poor corrosion resistance

But for a long time, although traditional tool materials have high hardness, they are brittle and poor in toughness, and their application is limited to a certain extent.
