Embodiment 1

[0054] The processing technology for producing tinned copper wire by using scrap copper wire includes the following steps:

[0055] S1, copper wire preparation

[0056] A. Crushing and separation of recycled copper waste

[0057] The recycled copper waste to be processed is sequentially crushed, vibrated, electrostatically separated, and magnetically separated to obtain recycled copper particles.

[0058] Among them, the recycled copper waste is waste copper wire, which is crushed by cutting machine and crusher in sequence. First, the waste copper wire is put into the cutting machine, and the cutting machine cuts it into small sections with an average of 100mm, and then the cut The scrap copper wire is put into the crusher, and the crusher crushes it and crushes it into a mixture of particles with an average of 4mm.

[0059] Vibration separation uses a vibration separator, put the particle mixture into the vibration separator, the dust in the particle mixture is flying, and ...

Abstract

The application relates to the technical field of copper wire processing, and specifically discloses a processing technology and a soaking and cleaning device for producing tinned copper wires using waste copper wires. The processing technology of tinned copper wire, which is prepared by copper wire, low temperature annealing, mixed blank wire drawing, crystallization annealing, surface roughening, surface tinning, to obtain tinned copper wire; the specific steps of copper wire preparation are as follows: the to-be-processed Recycled copper waste is crushed, vibrated, electrostatically separated, and magnetically separated in sequence to obtain recycled copper particles; the recovered copper particles are pickled, washed with cleaning solution, washed with water, and vacuum freeze-dried to obtain pretreated recycled copper materials; the copper materials are , Recycling the copper material for melting and mixing to obtain a mixed billet. The tinned copper wire processing technology not only realizes the utilization of recycled copper waste, but also makes the tinned copper wire have good Corrosion resistance, oxidation resistance, increase service life.

Description

technical field [0001] The application relates to the technical field of copper wire processing, more specifically, it relates to a processing technology for producing tinned copper wire by using waste copper wire and a soaking and cleaning device. Background technique [0002] Copper is a kind of soft metal. Because copper has the advantages of good ductility, thermal conductivity and electrical conductivity, it is widely used in cables, electrical and electronic components. Among them, the general step of copper wire in the related art is copper wire Material preparation, low temperature annealing, copper wire drawing, recrystallization annealing, etc. As the use of copper wires continues to increase, a large amount of waste copper wires will also be produced. In related technologies, the waste copper wires are generally pickled, then re-smelted, and made into copper wires, so as to realize the recycling of waste copper wires. use. [0003] In view of the above-mentioned...
