Processing technique for pin key

Abstract

The invention discloses a processing technique for a pin key. The technique comprises the steps of prefabrication of a blank part, installation of a die, installation and clamping of the blank part, processing and shaping, and part disassembly, through which a finished product can be obtained. Through application of the processing technique for the pin key disclosed by the invention, an existing method of making three sets of dies into a part is replaced by processing based on integration of a set of dies. The technique is concise; positioning of the shaped dies is adjustable; the same set of dies can be easily used to process multiple pin keys continuously at the same time, so production efficiency can be increased; the die production cost is low, and manufacture and repair are easy; and reliability and simpleness of the technique are proved in production practice. The compression shaping method has the advantages that pin key processing efficiency is high; the appearance surface quality is high; size consistency is high; and processing is stable and reliable. The production cost is greatly reduced; the cost and duration for die manufacture are reduced; and the technique is suitable for large-batch production. The technique is applied in production and product effects are very good.

Description

technical field [0001] The invention relates to the technical field of manufacturing pin keys, and in particular, relates to a processing method for pin keys. Background technique [0002] With the continuous development of science, pin and key parts can be widely used in various aspects of the aerospace field, such as aerospace vehicle parts, missile parts and ship parts. The existing pin key processing method adopts a three-step process: it is specifically divided into three sets of molds for flattening, edge trimming, and material cutting to make parts. It is difficult to grasp the size of the parts, because the size of the parts is small , It is very difficult to operate, and at the same time, it has high requirements for the manufacture of molds. [0003] Three sets of molds are used for processing and manufacturing. In the case of a large number of processed products, especially for mass production and processing, the failure rate of pin key parts is very high. Due to...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is to propose a kind of pin key processing method for the problems existing in the background technology, and the method of making the existing three sets of molds of flattening, edge trimming and material breaking into parts is changed to Integrated into processing on a set of moulds, in order to solve the situation that the size is difficult to grasp and control in the traditional method, and realize the continuous processing of one mold with multiple pieces, so as to improve production efficiency and reduce production costs
