Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] A grinding process for a forged knife blank with a radian, comprising the following steps:

[0016] S1. Select the stainless steel knife blank whose cross section is forged into a conical shape, and heat-treat the stainless steel knife blank for use; the carbide structure of the metal material after forging is more uniform, the grain is finer, and the distribution is more refined. High hardness, good tou...

Abstract

The invention discloses a polishing process of a forging cutter blank with radian. The polishing process mainly comprises the following steps that a stainless steel cutter blank with the cross section forged into a cone is selected, and the stainless steel cutter blank is subject to heat treatment for standby application; an edge formed by the end face of a grinding wheel of a levigator and the outer circumference of the grinding wheel is used for conducting first-step coarse grinding on a sinking arc face of the transverse middle portion of a cutter body, polishing is carried out from one end of the cutter blank longitudinal direction to the other end during coarse grinding, the end face of the grinding wheel of the levigator faces a cutting edge of the cutter blank, a grinding machine transverse face for a cutter back plane is firstly polished, and repeated machining is carried out back and forth. During coarse grinding, previous manual production is changed into mechanical machining, the cutter blank temperature in the polishing process cannot exceed 200 DEG C, and the hardness obtained after cutting cannot fall; and the lines, the thickness and the hardness of a cutter on the outer surface keep coincident, the product quality is stable, the rejection rate is low, the process is simple, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cutting tool production, and more specifically relates to a grinding process for a forged knife blank with a curvature. Background technique [0002] There are two kinds of knife blanks for processing and producing kitchen knives. One is stamped and sheared from stainless steel plates, and the other is stainless steel knife blanks formed by forging. The thickness of knife blanks formed by stamping and shearing stainless steel plates is consistent , during the process of smooth surface grinding, water mill mechanization can be carried out for a rough grinding and a fine grinding, high efficiency and large-scale mass production, beautiful appearance, stable product quality; the stainless steel knife blank formed by forging, through forging The carbide structure of the post-metal material is more uniform, the grain is finer, the distribution is more refined, the hardness is high, the toughness is good, the w...
