Cigarette lighter nozzle manufacture method and mould for the method

Abstract

The invention discloses a lighter nozzle manufacturing method and a mould for the method. The manufacturing method is supported with low carbon steel tubes as raw materials; the invention comprises such steps as cutting, cold heading, horizontal hole-punching and catwalk slot machining and etc. The mould, however, comprises a support, a first mould, a resetting spring, a first staple, a second mould, a third mould and a fourth mould; the first mould is assembled inside a through-hole in the support; the interior is opened with the first through-hole in the consistent external diameter as that of the front of the end-product nozzle; the second mould is composed of the second thimble fitting with the first through-hole, so as to form the front part of the nozzle; the fourth mould inside is composed of an aperture in an identical external diameter as that of the rear of the end-product nozzle; the aperture inside is provided with the fourth thimble, in order to form the rear part and the shoulder on the nozzle. The invention method has the advantages of simple technologies, high production efficiency, low raw-material cost and manufacturing expenses, and low consumption of materials and etc; the mould has the advantages of simple structure and convenient use, and therefore, in particular adapting to the manufacturing of lighter nozzles.

Description

technical field [0001] The invention relates to lighter parts, in particular to a manufacturing method of a lighter nozzle and a mold used in the method. Background technique [0002] At present, the competition in the lighter market is very fierce, and price reduction is usually one of the main means of competition for manufacturers. Therefore, how to control or reduce even a little production cost of lighters is of great importance to manufacturers. The nozzle is one of the parts of the lighter, and it is installed at the outlet of the gas storage chamber. When the lighter is in use, the gas in the gas storage chamber is sprayed out through the nozzle and ignited by the ignition mechanism. The manufacturing method of existing lighter nozzle generally has following several: 1, is raw material with copper bar, adopts modes processing moldings such as lathe turning and drilling machine punching. Its shortcomings are: high raw material prices, large material loss, many proce...

AI Technical Summary

Problems solved by technology

Its shortcomings are: high raw material prices, large material loss, many processing procedures, high processing costs and low production efficiency, and the copper nozzle also has the problem that the springboard groove is easy to wear and affect the quality of the product.

Its disadvantages are: high processing cost and low production efficiency; although the price of raw materials is lower than that of copper rods, it is still high; due to the problem of uneven pressure and flow during die-casting, it will make the molecules in the nozzle The structure is uneven, and the end-break rate of the finished product after assembly is high when it is inflated, which is likely to cause the whole machine to be scrapped; the springboard groove is also easy to wear and affect the quality of the lighter; The part of the tank wall is easily broken and the user cannot use it

It has high requirements on the ductility of raw materials, the processing is difficult, and there is a problem of material loss in the drilling process
