Tool and manufacturing method thereof

Abstract

The invention discloses a tool and a manufacturing method thereof. The tool comprises a tool body. The tool body is composed of a first tool body part and a second tool body part. The second tool body part is formed by fusion covering of the end edge of the first tool body part. The second tool body part is made of a hard alloy. A cutting edge is arranged on the cut edge, away from the first tool body part, of the second tool body part. The method includes the following steps that the first tool body part is formed in a punched manner; the end edge of the first tool body part is subjected to fusion covering to form the second tool body part; the cut edge, away from the first tool body part, of the second tool body part is subjected to edge forming to form the cutting edge; and the needed tool without a coating is manufactured accordingly. By means of the tool and the manufacturing method thereof, the hardness of the cutting edge, the toughness of the cutting edge and the wear resistance of the cutting edge can be effectively improved, and the beneficial effects that the forming technology is simple, the machining cost is low and batched production is easy are achieved.

Description

technical field [0001] The invention belongs to the field of tool forming, and more specifically relates to a tool and a preparation method thereof. Background technique [0002] Knives are indispensable tools in all walks of life and people's lives, such as utility knives, kitchen knives, table knives, military knives, machetes, fruit knives, scissors and other knives. The quantity is large, but the knives supplied on the market generally have the problem of low hardness and durability of the cutting edge, and the knives need to be sharpened frequently. In particular, for kitchen knives such as table knives, fruit knives, and scissors, the problem of durable sharpness of the knives is becoming a technical problem of great concern in related fields. [0003] In order to solve the above problems, some solutions have been proposed in the prior art. For example: 1) It is made of stainless steel material and quenching heat treatment; 2) It is made of high hardness carbide (WC,...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a cutting tool and its preparation method, in which the cladding 3D printing method is adopted to directly cladding form a part of the knife body and cutting edge with a three-dimensional structure, avoiding the The problem of complex forming process, long production time and high production cost caused by the need to specially form the nickel alloy layer can effectively improve the hardness and toughness of the cutting edge, improve the wear resistance of the cutting edge, and solve the problem of improving the sharpness of the existing technology. It has the advantages of simple forming process, low processing cost and easy mass production
