Abstract

The invention discloses a preparation process of a ram-type spectacle case. According to the technical scheme, the preparation process is characterized by comprising the following steps of: S1, punching of a case body: punching and drawing out a case body comprising an upper portion and a lower portion through a drawing die, and using a side punching die to punch holes in one side of the lower portion; S2, side line treatment on the case body: deburring the punching side lines of the case body; S3, welding of inserts: welding elastic clamping pieces matched with the punched holes in the lower portion to one side of the upper portion; S4, surface treatment on the case body: carrying out surface treatment on the surface of the case body; S5, injection molding of an outer protection layer: placing the case body in an injection mold, and injecting a layer of resin material on the surface of the case body in a coating manner; S6, correction of waste at a water gap: removing waste at an injection molding water gap; S7, preparation of a fabric layer; S8, covering of the fabric layer; and S9, trimming of the fabric layer. The spectacle case prepared by the preparation process of a ram-type spectacle case has the advantages of high strength, drop resistance, difficulty in damage, long service life, difficulty in dirt accumulation and the like.

Description

technical field [0001] The invention relates to the field of spectacle case processing, in particular to a preparation process of a stamped spectacle case. Background technique [0002] Most of the glasses cases currently used are all-plastic glasses cases. The all-plastic glasses case adopts one-time injection molding, and one side of the upper and lower covers is connected by soft plastic. This spectacle case has poor impact resistance, is easily damaged, and has a short service life. [0003] Existing publication number is the Chinese patent of CN110511970A, and it discloses a kind of manufacturing method based on bacterial cellulose material glasses case shell, belongs to chemical industry, comprises the following steps: (1) the production of bacterial cellulose. First activate the Gluconacetobacter xylinum, then inoculate the seed solution of the activated Gluconacetobacter xylinum into the culture medium according to a certain volume ratio of the inoculum, and put it...
