Elastic eyeglass feet and its preparation method

Abstract

An elastic glass foot includes a foot body, a case placed at the end of the foot body, a spring core, a hinge joint and a pile crown, in which the front end of the case is opened, the middle contains part of the spring core, the outside end of which is hinged with the hinged joint, the above foot body is linked with the case and the hinged chain is connected with the pile crown as core. At the same time, there is no riverting point or hole at the foot surface, in operation, riverting point is made on the projection of rough part then to be removed by saw, and milling cutting.

Description

technical field [0001] The invention belongs to the technical field of spectacles, in particular to a spectacle temple with elasticity and a manufacturing method thereof. Background technique [0002] As we all know, elastic temples have been widely used in glasses. Since the elastic glasses feet can be rotated outward by a small angle when they are in the open position, the elastic glasses feet can clamp the wearer's head so that the glasses can be firmly worn. [0003] In elastic glasses feet, the feet and hinges of the glasses feet are hinged by a spring core. The spring core is placed in the housing at the end of the temple. [0004] like Figure 7 As shown, in the traditional push-plate type spring eyeglasses, the foot body 1 and the shell 2, the hinge 3 and the pile head 4 are all connected together by welding. In the production process, the shell 2 is welded with the foot body 1 after the spring core 5 is installed, so the high temperature o...

AI Technical Summary

Problems solved by technology

In the production process, the shell 2 is welded with the foot body 1 after the spring core 5 is installed, so the high temperature of welding may easily lead to insufficient annealing elasticity of the spring core 5 in the shell 2, and the welding will be between the shell 2 and the foot body 1 Leave weld marks, affect the appearance

At the same time, welding will also produce phenomena such as virtual welding and empty welding, which makes it difficult to guarantee the product quality of the glasses feet.

[0005] There is also a production process that uses the feet and the shell as one piece, but in this process, punching riveting is needed to fix the spring core in the shell, so there will be riveting pits on the outside of the glasses feet, which will directly affect the glasses. good looking feet
