Description

Many acute angles one-shot forming auxiliary switch accessory in high precision

Technical field

This utility model switch auxiliary accessories technical field, a kind of high accuracy many acute angles one-shot forming auxiliary is opened Close accessory.

Background technology

High pressure auxiliary switch five metals spare and accessory parts all use single punch-die to complete in manufacturing process at present, high-accuracy many acute angles Molding uses split type molding mode, and precision is the highest, and electric conductivity is bad, causes auxiliary switch to there is potential safety hazard.

Summary of the invention

In order to solve problem above, the purpose of this utility model is to provide a kind of high accuracy many acute angles one-shot forming auxiliary Switch fitting.

Be the technical scheme is that by realizing the purpose of this utility model

A kind of high accuracy many acute angles one-shot forming auxiliary switch accessory, switch fitting entirety is in the shape of the letter V structure, and tip be horizontal stroke To turnover handle, end is for laterally to turn down flange, and middle part is circular arc V-Bottom, forms the 3rd bending place；Laterally turnover handle is by first Linking arm is connected with one at the bottom of circular arc, forms the first bending place；Circular arc V-Bottom is by the second linking arm and laterally turns down flange One connects, and forms the second bending place.It is stamped with circular hole in the middle part of described horizontal turnover handle.

The beneficial effects of the utility model are:

This utility model improves structural strength, it is achieved many acute angles one-shot forming in high precision, and switch overall appearance is clean and tidy, hard Gu it is stable.
