Problems solved by technology

At present, the method of producing long-life soldering iron tips at home and abroad is to process the copper rod into a copper substrate, and then go through the processes of iron plating, nickel plating, and chrome plating (working surface) in turn to prepare the finished soldering iron tip. It has good mechanical strength and tin corrosion resistance. Nickel plating and chromium plating can be used as an additional protective layer, which can make the iron coating more compact and prevent the infiltration of tin on the surface. The quality of the soldering iron tip has a direct impact
The production cost of soldering iron tip is high, and the quality is unstable, which has become a problem that plagues the development of the soldering iron tip industry

Embodiment 1

[0025] A method for preparing a long-life, low-cost soldering iron tip: comprising the following steps:

[0026] S1: Ingredients: prepare the raw material CuFe master alloy, the mass ratio of Cu and Fe in the CuFe master alloy is 1:1, the size of the electrolytic copper plate is 0.2m*0.1m*0.05m, and the size of the CuFe master alloy is 0.1m*0.1 m*0.02m, control the mass percentage of Fe element in the raw material at 50%, too large metal volume is not conducive to controlling the content of Fe in the ingredients, and too small metal volume is easy to oxidize the metal;

[0027] S2: Vacuum smelting: Put the raw materials prepared in S1 into a vacuum induction furnace, and vacuumize the vacuum induction furnace. When the vacuum degree in the vacuum induction furnace reaches р=4Pa, start heating and adjust the vacuum The power of the induction furnace is 20KW, continue heating for 10 minutes, then increase the power of the vacuum induction furnace to 40KW, continue heating for 10...

Embodiment 2

[0033] A method for preparing a long-life, low-cost soldering iron tip: comprising the following steps:

[0034] S1: Ingredients: Prepare the raw material electrolytic copper plate and CuFe master alloy. The mass ratio of Cu and Fe in the CuFe master alloy is 1:1. During the batching, the mass percentage of Fe element in the raw material is controlled at 40%, and the electrolytic copper plate The size is 0.2m*0.1m*0.05m, and the CuFe master alloy size is 0.1m*0.1m*0.02m. Too large a metal volume is not conducive to controlling the content of Fe in the ingredients, and too small a metal volume is easy to oxidize the metal;

[0035]S2: Vacuum smelting: Put the raw materials prepared in S1 into a vacuum induction furnace, and vacuumize the vacuum induction furnace. When the vacuum degree in the vacuum induction furnace reaches р=3Pa, start heating and adjust the vacuum The power of the induction furnace is 25KW, continue heating for 8 minutes, then increase the power of the vacuu...

Abstract

The invention discloses a preparation method of a soldering bit with long service life and low cost. The preparation method comprises the following steps of S1, material preparation, S2, vacuum melting, S3, casting, S4, hot forging, turning of an outer circle, S5, drawing and intermediate annealing, and S6, machining. According to the preparation method of the soldering bit with long service lifeand low cost, the soldering bit is prepared from a CuFe alloy material and has the advantages of being long in service life, high in corrosion resistance and low in production cost, the heat conduction efficiency of the soldering bit can be controlled by adjusting the proportion of the copper content to the iron content, and the application occasion is wider.

Description

technical field [0001] The invention relates to the technical field of ferrous metal alloys, in particular to a method for preparing a long-life and low-cost soldering iron tip. Background technique [0002] With the rapid development of the modern electronic industry, soldering technology has also been developed rapidly. In recent years, soldering technology mostly uses lead-free solder with high working temperature, and the soldering process requires that the soldering iron tip can be continuous and long-term. time to work. Therefore, higher requirements are put forward for the high temperature resistance, oxidation resistance and corrosion resistance of the soldering iron tip material. At present, the method of producing long-life soldering iron tips at home and abroad is to process the copper rod into a copper substrate, and then go through the processes of iron plating, nickel plating, and chrome plating (working surface) in turn to prepare the finished soldering iron ...
