Problems solved by technology

[0004] In the current technology, the domestic orthodontic brackets are generally manufactured by the method of wire cutting machine tool processing. The smoothness and precision of the orthodontic brackets manufactured by this method cannot meet the requirements of clinical satisfaction, and the quality is lower than the international level.
In foreign countries, special machine tool cutting, precision casting split welding or powder casting are generally used for manufacturing. The cost of special machine tools and casting processes is high and the productivity is low.

Embodiment Construction

[0012] According to the attached figure 1 Specific embodiments of the present invention will be described in detail.

[0013] 1. Hot rolling

[0014] As shown in the figure, the square steel billet is heated to the plastic deformation temperature, placed at A, and rolled into A shape by the first roller 1 and the second roller 2. The A-type thermal support blank that is rolled out continues to B, and is rotated and rolled into B-type by the first roll 1 and the second roll 2. The B-type thermal bracket blanks extruded by the rollers are continued to be placed at C, and the first roller 1 and the second roller 2 are rotated and rolled to form an embryo whose size is close to that of the orthodontic brackets.

[0015] 2. Cold-formed ligature wing and bottom plate knurling

[0016] As shown in the figure, after the hot roller pressed embryo is naturally cooled to room temperature, it is placed at D, and the ligature wing and the bottom plate are knurled by cold bending to make...

Abstract

The rolling process of producing orthopedic bracket includes: hot rolling steel billet into initial blank with size near that of orthopedic bracket, cold bending the tying wings and knurling the base board to form the refined blank, trimming and finish machining the square slot, and cutting to obtain orthopedic bracket for clinical use. The said process has high precision, high smooth degree, high production efficiency, low production cost and simple operation.

Description

technical field [0001] The invention relates to a tooth orthodontic device, in particular to a method for manufacturing an orthodontic bracket by a rolling method. Background technique [0002] Dental orthodontic brackets are equipment for orthodontics. The demand for this equipment is large to meet the needs of orthodontics for 60-70% of the population. It is an important equipment that is directly related to the health and beauty of many people. [0003] For the correction of tooth deformity, several brackets are usually bonded to a row of teeth to support the applied arch wire. There is a cross groove in the center of the bracket, and there are ligature wings on the upper and lower sides. In the transverse groove of the cross groove on each bracket, the dental arch wire is fixed on the bracket with a ligature wire, and the deformed teeth are gradually corrected by using the elasticity of the dental arch wire. Currently used brackets include metal brackets, ceramic bracke...
