Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0046] Such as Figure 1-2 As shown, the wear-resistant pliers of the present invention include a first pliers body and a second pliers body connected together by a pivot, and the first handle 11 of the first pliers body corresponds to the second handle 21 of the second pliers body It is for the user to hold and operate, so that the first head of the first pliers cooperates with the second head of the second pliers to realize cutting. In the present invention, the first head and the second head are assembled on the first pliers 12 and the second pliers 22 respectively. Figure 6 Shown cutting edge 31 or Figure 5 The shearing edge 32 shown is formed.

[0047] The cutting edge can be as figure 1 The shown welding is on the first clamp head and the second clamp head, and the welding method is as follows:

[0048] a. Pre-fix the cutting edge on the...

Abstract

The invention discloses a cutting edge material, wear-resistant pliers and a manufacturing method of the wear-resistant pliers, belongs to the technology of hardware tool materials, solves the problem that the cutting life of a cutting edge of the existing pliers is short by improving the material of a cutting edge and improving the hardness and the wear resistance of the cutting edge by solving the problem that the cutting life of the cutting edge of the existing pliers is short due to the fact that a jaw is cracked and worn seriously in the using process of the existing pliers, and the cutting life of the cutting edge is greatly prolonged.

Description

technical field [0001] The invention belongs to the hardware tool material technology, and in particular relates to a cutting edge material, a wear-resistant pliers and a manufacturing method thereof. Background technique [0002] In the existing pliers, the cutting edge and the pliers head are usually made of the same material, and the cutting edge is directly processed on the pliers head. During the user's use, the cutting edge often breaks, and the cutting edge wears seriously, which leads to a decrease in the life of the cutting edge. Seriously, it cannot meet the user's requirements for the wear resistance and hardness of the cutting edge. There are some existing bimetallic pliers, the cutting edge is made of alloy steel, the pliers head is made of ordinary steel, and is processed by welding. Although the hardness and wear resistance have been improved to a certain extent, there are still cracks in the jaws during use, which cause serious wear and tear. The problem of ...
