Processing technique for forming air nozzle of lighter

Abstract

The invention relates to a method for producing air nozzle of lighter, wherein it comprises that: 1, feeding material that preparing cylinder blank at 1. 1-1. 15 volume times than nozzle; 2, pre-punching that punching ----shaped concave at the center of two ends, while the concave diameter is 1. 2-1. 25 times of central hole; 3, holing that connecting two side concaves while the diameter is 1. 1-1. 2 times of central hole; 4, compressing that compressing the central through hole and shoulder of outer face; 5, using special machine to prepare head and tail. The invention mainly uses cold punch method to improve efficiency. And it can not only use copper, with low cost and simple process.

Description

technical field [0001] The invention relates to a forming process of a gas nozzle of a lighter. Background technique [0002] Due to fierce competition in the existing lighter market, manufacturers compete to lower prices as the main means of competition, resulting in very narrow profit margins, which makes some enterprises unbearable and even unsustainable. Therefore, if the production of spare parts can be reduced even a little Production costs, are very meaningful. Among them, the existing processing technology of the lighter gas nozzle generally has the following types: one is to use copper rods as raw materials and process them with instrument lathes. The disadvantages of this method are high raw material prices, high raw material loss, and low production efficiency; One is to use aluminum tubes as raw materials and make them by roll forming. The advantage of this method is that the material cost is low, but the processing technology is complicated, so the processing c...

[0002] Due to fierce competition in the existing lighter market, manufacturers compete to lower prices as the main means of competition, resulting in very narrow profit margins, which makes some enterprises unbearable and even unsustainable.

Among them, the existing processing technology of the lighter gas nozzle generally has the following types: one is to use copper rods as raw materials and process them with instrument lathes. The disadvantages of this method are high raw material prices, high raw material loss, and low production efficiency; One is to use aluminum tubes as raw materials and make them by roll forming. The advantage of this method is that the material cost is low, but the processing technology is complicated, so the processing cost is high; the other is the metal die-casting method. The material of this method is The cost and processing cost are high, and the production efficiency is low, so it is rarely used

In comparison, stamping or cold heading is the most efficient and economical way to process parts. However, due to the small size of the gas nozzle of the lighter, the machining accuracy is high, especially the diameter of the central axial through hole is only 0.8mm. , or even smaller, the ratio of length to diameter is over 15, and in order to facilitate the processing of the air intake horizontal hole at the lower part of the nozzle, the wall thickness of the lower part should be thinner, and the through hole in the lower part is required to have a larger diameter and a stepped hole, so now Some stamping or cold heading processing technology has been difficult to solve
