Embodiment 1

[0074] A method for processing slender and shaped pins for spectacle legs, comprising the following steps:

[0075] S1. The material is cut off after leaving the warehouse, quenched in a salt bath and straightened by heat, and the straightness is guaranteed to be within 0.02;

[0076] S2. The centerless grinder uniformly processes the upper and lower dimensions of the rod material, that is, 10.5mm to 10.6mm, within Ra0.2. The specific steps are:

[0077] The rod material is φ11mm round material, and the centerless grinder rounds the outer circle and controls the straightness within 0.04. Centerless grinding is divided into rough grinding and fine grinding: when rough grinding, the roughness of the grinding wheel can reach Ra2.5-3.6, which is easy To remove the curvature of the material, the rough machining of the product is divided into three times, and the measurement should be done slowly. The first round is enough, the second time is slowly lowered to grind away 0.03mm, the...

Embodiment 2

[0099] A processing system adopted in the method for processing the slender shape of the spectacle legs described in Embodiment 1, including a surface grinder system and a polishing system;

[0100] The surface grinder system includes a working magnetic table of the machine tool and a surface grinding mechanism for each part;

[0101] The flat grinding mechanism of each position includes:

[0102] The process surface flat grinding mechanism is composed of a rear stopper 1, a side stopper 2, and a grinding wheel. The rear stopper 1 withstands one end of the product, and the side stopper 2 clamps both sides of the product;

[0103] 3.0mm thick first side flat grinding mechanism, composed of rear stopper 23 and grinding wheel 2, rear stopper 23 withstands one end of the product;

[0104] The second surface flat grinding mechanism of the 3.0mm thickness part is composed of a rear stopper 34 and a grinding wheel 3, and the rear stopper 34 withstands one end of the product;

[010...

Abstract

The invention belongs to the eyewear industry and particularly relates to a machining technology for a slender molded contact pin of a glasses leg. A system for machining the slender molded contact pin of the glasses leg is adopted to perform a series of fine machining including plane abrasion, polishing and the like on all parts of a product. The machining process and system are simple, and the machining method is feasible and can guarantee technical requirements. Not only is the problem that a domestic contact pin is difficult to guarantee the technical requirements solved, but also the machining difficulty and the production cost are reduced. More enterprises in China can produce the product that meets the technical requirements. Thus, the product is more competitive in the market.

Description

technical field [0001] The invention belongs to the glasses industry, and in particular relates to the processing technology of slender and shaped pins for glasses legs. Background technique [0002] Glasses are widely used in human society, especially with the rapid development of electronic products, eye vision problems from children to the elderly are rising sharply every year, and in order to better correct vision and wear comfortably, the requirements for glasses are getting higher and higher , which requires the glasses industry to continuously improve the quality, comfort and durability of their glasses to meet customer needs. As an integral part of glasses, the slender and shaped pins of glasses legs are known for their high technical requirements and difficult processing. At present, domestic The production technology cannot meet the requirements. The product is relatively slender and prone to bending deformation, and the symmetry and straightness are difficult to c...
