A manufacturing process of mirror legs

Abstract

The invention relates to the field of glasses manufacturing and provides a manufacturing technology of glasses legs. The manufacturing technology comprises the first step of copper male die manufacturing, the second step of oil-pressure die manufacturing, the third step of extrusion forming and the fourth step of edge cutting. A merging principle is adopted in the manufacturing technology of the glasses legs, a fine machining edge is arranged on a lower fine plate of a lower edge cutting die, and a rough machining edge is arranged on a lower rough plate of the lower edge cutting die. Thus, rough machining and fine machining for the glasses legs can be completed at the same time in the edge cutting process of the glasses legs, an original technological process is effectively simplified, and the product cycle is shortened. Meanwhile, one set of equipment and one operator can be omitted. Besides, productivity is improved by a half, and standard performance is more stable.

Description

technical field [0001] The invention relates to the field of glasses manufacturing, in particular to a manufacturing process of mirror legs. Background technique [0002] At present, in the manufacturing process of the mirror legs, fast wire-feeding rough machining is often used to remove excess edge material, and then slow wire-feeding finishing is used to remove a small amount of remaining material. To achieve a smooth effect on the cut surface, there will be two or more rough machining processes in one process, resulting in two or more sets of materials on the mold material, and the operator has to repeat one process , the processing speed of the product will be slow. The description of the existing technical process: straight line→turning→grinding→oil pressure→flash→grinding 2→fine flying→grinding 3→cleaning→quality inspection. In this production process, the repeated production process has Twice, and increased machine equipment, manpower, and time. Although the existin...

Problems solved by technology

[0003] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of manufacturing process of mirror leg, aim to solve the manufacturing process of existing mirror leg is more complicated, can't uniform one-time positioning processing, causes processing effect not good, and The shortcoming that the milling standard parts in the post-process cannot match the standard molds will affect the processing precision and stability of subsequent products, and seriously affect the structural stability of the entire pair of glasses.
