Manufacturing process of cheek-through type dental forceps

Abstract

The invention discloses a manufacturing process of a pair of cheek-through type dental forceps. The manufacturing process includes the following steps: 1, acquiring a male sheet semi-finished product and a female sheet semi-finished product through casting; 2, using a sand skin to remove an oxide layer of a cheek portion of the male sheet semi-finished product; 3, high-frequency heating the female sheet semi-finished product to above 700 DEG C, opening two cheeks of the cheek portion of the female sheet semi-finished product to form an arc through hole, inserting the male sheet semi-finished product into the female sheet semi-finished product through the arc through hole, and aligning the cheek portions of the male sheet semi-finished product and the female sheet semi-finished product; 4, beating the female sheet semi-finished product, allowing the two cheeks of the female sheet semi-finished product to be closed and aligning heads of the two cheeks; 5, drilling a through hole in the center of the female sheet semi-finished product as a reference; 6, putting a circular bar in the through hole, beating two ends of the circular bar so as to fix two ends at the dental forceps, of the circular bar; 7, completely welding and fixing the two ends of the circular bar and the dental forceps together; 8, handle pattern rolling; and 9, polishing treatment. The beneficial effects of the invention are that the manufacturing process is simple and is low in cost; and the manufactured dental forceps are high in precision, are beautiful in appearance, are anti-corrosion, are high in strength, are easy to use, and are long in service life.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a manufacturing process of gill-piercing tooth extraction forceps with corrosion resistance, high strength, high product precision, low cost and long service life. Background technique [0002] Tooth extraction forceps are pliers used to extract teeth during tooth extraction. Almost all tooth extraction forceps on the market are forged from 2cr13 material. The blank is processed by 4-6 milling processes. The precision of the blank is poor and requires a lot of manual grinding. Rust, chrome plating has good wear resistance, but chrome plating has a relatively large toxin, and there is also a risk of the coating falling off. Therefore, it is difficult to completely cover the coating, so it is easy to rust and affect the use. [0003] Moreover, most of the existing tooth extraction forceps are jaw-stacking forceps. Since the appearance is connected by rivets, there are obvi...

AI Technical Summary

Problems solved by technology

Almost all tooth extraction forceps on the market are forged from 2cr13 material. The blank is processed by 4-6 milling processes. The precision of the blank is poor and requires a lot of manual grinding. Rust, chrome plating has good wear resistance, but chrome plating has a high toxin and there is a risk of the coating falling off. Therefore, it is difficult to completely cover the coating, so it is easy to rust and affect the use

[0003] Moreover, most of the existing tooth extraction forceps are jaw-stacking forceps. Since the appearance is connected by rivets, there are obvious gaps when using it. The whole is rough and not delicate, which affects the appearance; the upper and lower pieces must swing a lot when using it. , inconvenient to use; and the rivets are manually knocked on, and after frequent opening and closing wear, the pliers are easy to swing, which will increase the degree of swing, affect the comfort of use, and shorten the service life of the tooth extraction forceps
