Processing technology and material of rotary asymmetrical self-retractable spring belt buckle

Abstract

The invention belongs to the technical field of mechanical manufacturing, and discloses a processing technology and material of a rotary asymmetrical self-retractable spring belt buckle. By combiningwith a newest buckle head product structure and production technology on the market and technical characteristic information, and widely researching and collecting using experience and improvement demand information of consumers, three-dimensional forming dynamic data are adopted to analyze software integration input systematic data, all parameters of a stamping part model and a buckle head structure model meeting all design technical indexes are generated by simulation, and a stamping technology of buckle head manufacturing and operating procedures and parameters of adopted equipment are made. According to the processing technology of the rotary asymmetrical self-retractable spring belt buckle, the process is reasonable and scientific, the operating process is simple and controllable, thus stamping production of a belt buckle head is easier to realize, and the elegant appearance is achieved; and technologies such as electroplating of traditional schemes are omitted, the product quality is guaranteed, the product yield is increased, the stamping efficiency can be improved greatly, and the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a processing technology and material of a rotary asymmetric self-expanding spring belt buckle. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Belt buckles currently on the market are usually formed by melting the material through an injection molding machine, casting it with a mold, and then undergoing various post-processing processes such as polishing and electroplating. The traditional process of making buckles is to melt the material through an injection molding machine, cast it with a mold, and then undergo various post-processing processes such as polishing and electroplating. After a period of use, it is easy to produce scratches, and the color of the scratches and the plating surface is different, which affects the appearance. [0004] In addition to zinc alloy, trad...

AI Technical Summary

Problems solved by technology

[0006] (1) The workmanship is single, the mold casting is formed, and the post-polishing and electroplating processes make the product surface prone to scratches and affect the appearance

[0007] (2) There are many casting production processes, the process control is cumbersome, and it is easy to produce waste products

[0008] (3) The structure of the casting is not dense enough, there are defects such as shrinkage cavities, pores, slag, cracks, etc., the grain size is uneven, the mechanical properties of the casting are low, and the impact resistance is low;

[0009] (4) There will be a lot of uncertainty during casting, resulting in errors in the size of the castings, resulting in scrapped products

[0010] (5) There is a risk of pollution in the electroplating process

The electroplating layer of the belt buckle is exposed to the alkaline environment dormitory during use, and there is a risk of heavy metal hazards to the human body

[0011] (6) Limited by the process, the material used in the product is restricted

[0012] (7) The material cost is higher
