BG42 stainless steel medical clamp and manufacturing method thereof

Abstract

The invention provides a BG42 stainless steel medical clamp. The BG42 stainless steel medical clamp comprises a clamp body with a clamp head, and the clamp head is provided with a step. The BG42 stainless steel medical clamp is characterized in that BG42 stainless steel is welded to the step through paste nickel-based brazing alloy; the clamp body is made of quenched low-carbon stainless steel materials with HRC more than 30; the BG42 stainless steel is formed by mixing C, Si, Mn, Cr, Mo and V and comprises, by mass, 1.0-1.2% of C, 0.2-0.4% of Si, 0.4-0.6% of Mn, 14-15% of Cr, 3-5% of Mo and 1.1-1.3% of V; the paste nickel-based brazing alloy is formed by mixing Cr, B, Si, Fe, C, P and Ni and comprises, by mass, 6-8% of Cr, 2.75-3.5% of B, 4-5% of Si, 2.5-3.5% of Fe, 0.05-0.07% of C, 0.01-0.03% of P, and the balance Ni.

Description

technical field [0001] The invention relates to a manufacturing process of medical jaws, in particular to a manufacturing process of oral medical jaws. Background technique [0002] The structures of the existing medical instrument forceps and scissors blades basically have the following types: [0003] 1. The whole medical forceps is made of medium carbon stainless steel material, which is directly processed into a knife edge after quenching. This type of knife edge cannot meet the requirement of cutting steel wire because the hardness of the material of stainless steel itself is not high after quenching. [0004] 2. The whole medical forceps is made of high-carbon stainless steel material, which is directly processed into a knife edge after quenching. This type of knife edge, because the overall hardness of the stainless steel itself is too high after quenching, the body of the pliers is brittle and difficult to process. Because such materials generally have high carbon...

AI Technical Summary

Problems solved by technology

Although the problem of the hardness of the knife edge processed by this method has been solved, due to the poor welding performance of low or medium carbon stainless steel and the high hardness material of the jaw, it is difficult to weld two different materials together, so brazing is generally used. After welding, the color of the welding place is easy to change, and the cutter head is easy to fall off
