Machine and method for trimming and shaping ceramic power insulators after they are manufactured

Abstract

The invention relates to a blank trimming and shaping machine used after ceramic electric power insulator manufacturing and forming and a method. The blank trimming and shaping machine comprises a work table, positioning mechanisms and trimming mechanisms. The positioning mechanisms are installed on the middle portion of the work table. The trimming mechanisms are symmetrically installed on the front side and the rear side of the work table. Positioning grooves are evenly formed in the middle portion of the work table from left to right. Slide grooves are symmetrically formed in the front sideand the rear side of each positioning groove. Each slide groove and the corresponding positioning groove communicate with each other. Each positioning mechanism comprises a rotation plate, a positioning frame, a connection rod, a drive worm wheel, a rotation rod and a drive worm. Each trimming mechanism comprises a slide block, a connection plate, fixing screws, an installation plate, trimming branch chains and regulation rods. According to the blank trimming and shaping machine and the method, in the process of polishing and trimming insulator blank bodies, by wetting the blank bodies through wetting modules, certain softening can be conducted on the blank bodies, and therefore the blank trimming difficulty is lowered; and dust generated during polishing can also be reduced, the multipleinsulator blank bodies can be trimmed at a time, and the machining efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of ceramic insulator processing, in particular to a machine and method for trimming and shaping ceramic power insulators after they are manufactured and formed. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. [0003] Among them, when manufacturing and processing ceramic insulators, it is necessary to go through the step of trimming to ensure the appearance quality of the finished insulator. At present, the trimming of ceramic insulator bodies mainly includes dry repairing and wet repairing. These two methods There are some probl...

Problems solved by technology

[0004] (1) Wet repair is carried out when the body contains a lot of water and is still wet and soft. It is suitable for bodies with complex shapes or wet joints. At this time, the operation is easier and the knife for trimming is not easy to wear. Its disadvantages It is easy to cause damage to the blank during moving and operation, causing deformation and affecting the appearance quality of the finished product;

[0005] (2) Dry repair is carried out when the water in the green body is less. At this time, the strength of the green body is improved, which can reduce the deformation caused by moving and injury, which is beneficial to improve the quality. The disadvantage is that the dust is relatively large, Moreover, the resistance to the trimming knife is relatively large, it is easy to jump the knife, the wear of the trimming knife is also large, and the operation technique is difficult to master
