Production method of crimping fittings

Abstract

The invention discloses a production method of crimping fittings for cable connectors. Metal pipes are used for producing crimping fittings. The method comprises the following steps that first one end of a metal pipe is stamped by a stamping die to form a crimping piece, meanwhile, the other end of the metal pipe forms a connecting pipe; then, the crimping piece is stamped to form a fixed hole of the crimping fitting; and finally, two sides of the crimping piece are cut. The methods uses the metal pipe to produce the crimping fitting, uses the stamping die to stamp one end of the metal pipe to form the crimping piece and forms the connecting pipe at the other end of the metal pipe. Compared with the prior art, this method saves the large amount of energy consumed by providing a large amount of impact energy, and the die and wear cost for stamping a hollow connecting pipe, and also eliminates the need for punching and the corresponding manpower. Therefore, the production method reduces the production cost from aspects of energy, die and manpower, and is simple.

Description

technical field [0001] The invention relates to a crimping fitting, in particular to a crimping fitting for a cable connector. Background technique [0002] There is a crimping fitting inside the cable connector, and the crimping fitting includes a connecting pipe and a crimping piece connected with the connecting pipe. The lumen of the connecting tube is used to accommodate the conductors of the wires and cables, and the crimping piece is crimped with the conductors in the cable connector. [0003] When manufacturing the above-mentioned crimping fittings, first use a stamping die to align the punching rod of the die with the center of the metal rod and punch it to form a hollow connecting pipe on a section of the metal rod; then, punch the other end of the metal rod to form a crimping piece; finally , Punch and form a fixed space on the crimping piece. [0004] However, the manufacturing process of the above-mentioned crimping fittings is relatively complicated. When stam...

Problems solved by technology

[0004] However, the manufacturing process of the above-mentioned crimping fittings is relatively complicated. When stamping a metal rod to form a hollow connecting pipe, a huge punching force is required to form the hollow connecting pipe. This will not only consume a lot of energy due to the large impact energy provided, but also Moreover, the cost of the mold will be increased due to the large amount of wear and tear of the mold so that the stamping rod of the mold must be replaced frequently, and the labor cost will also increase due to the stamping procedure.
