Embodiment 1

[0038] The process flow of a kind of high-speed steel replaceable face type insert in embodiment 1 is basically as attached figure 1 As shown, it specifically includes the following steps:

[0039] Step 1: Prepare high-speed steel plate raw material, the type of high-speed steel plate raw material is high-speed steel W6Mo5Cr4V2;

[0040] Step 2: cold-rolling the high-speed steel plate raw material in step 1 to form a high-speed steel plate;

[0041] Step 3: stamping the high-speed steel plate in step 2 to form a rough blade; the surface of the rough blade after punching the blank is in a square shape, and at the same time, vertically set a mounting hole 101 at the center of the rough blade;

[0042] Step 4: Carry out vacuum quenching to the rough blade in step 3, and quench and heat the rough blade in stages; figure 2 As shown, in the first stage of quenching, the rough blade is heated to 640-660°C at a uniform speed, and the temperature is maintained for 2.4-2.5h; in the s...

Abstract

The invention relates to the field of blade machining, and particularly discloses a machining process for a high-speed steel surface-replaceable blade. The machining process comprises a high-speed steel plate raw material preparing step; a cold rolling treatment step; a punching blank making step; a vacuum quenching and tempering treatment step; and an edge grinding machining step, and thus the blade finished product is formed. According to the technical scheme, after the quenching treatment and tempering treatment in the step 4 are carried out, the hardness of the refined blade made of high-speed steel is 63-70 HRC and is smaller than that of a blade made of a conventional hard alloy material, then edging of the refined blade is easier and more convenient during edge grinding machining, thus the edging strength of the refined blade can be effectively reduced, and the machining cost is reduced.

Description

technical field [0001] The invention belongs to the field of blade processing, and in particular relates to a processing technology of a high-speed steel replaceable blade. Background technique [0002] A planer is a tool used for planing and has a cutting edge. It is often detachably mounted on a planer shaft. The rotating planer shaft drives several planers to rotate synchronously, and the blades plan the surface of the wood. [0003] Conventional planers are mostly made of hard alloy materials, which are pressed by raw materials and vacuum sintered to form blanks, and then machined to finished products. The hardness of the cemented carbide material is greater than or equal to 91HRA, and the hardness is relatively hard, which directly leads to a higher cost of machining; at the same time, due to the high price of the cemented carbide material itself, it further leads to a higher cost of the finished planer. Contents of the invention [0004] The present invention intend...
