Movable welding point metal ion re-plating machine and re-plating method thereof

Abstract

The invention belongs to the field of wire production, and particularly relates to a movable welding point metal ion re-plating machine and a re-plating method thereof. The machine comprises a car body. A plating solution tank is arranged on the table face of the car body. Anode plates are put in a left tank cavity and a right tank cavity, and the anode plates are connected to the positive pole of a power source through an anode wire. The machine further comprises a turnover plate, and the top end of the turnover plate is fixedly connected with a re-plating plate. Two bosses used for straightening and locating a to-be-re-plated copper wire are arranged at the top end of the re-plating plate in a convex manner. The re-plating plate is connected to the negative pole of the power source through a cathode wire. The machine has the beneficial effects of being simple in structure, flexible and convenient to use and reliable and stable in work, the production cost is ensured, and meanwhile the product quality of the tin-plated copper wire can be effectively guaranteed. The method comprises the following steps that tin plating master batch welding and connector grinding treatment are carried out to obtain the to-be-re-plated copper wire; and then oil removal and re-plating operation are carried out. The efficiency and reliability of the tin plating process can be effectively ensured through the above method.

Description

technical field [0001] The invention belongs to the field of wire rod production, and in particular relates to a metal ion replating machine for mobile welding points and a replating method thereof. Background technique [0002] The production process of copper wire is actually a gradual shape change process from copper plate to copper rod and then to copper wire. The thin copper wire that has just been pulled out is easily oxidized due to the lubricating oil on the surface, so it should be tinned as soon as possible to form a protective layer on the surface of the copper wire. Since the length of each copper rod is limited, it is necessary to splice multiple copper wires end to end to make a whole roll of tinned copper wire. Most of the existing joint operations between copper wires are realized by cold pressure welding, etc., and there are the following problems: whether it is cold pressure welding or other existing copper wire joint welding methods, it will inevitably da...

AI Technical Summary

Problems solved by technology

Most of the existing joint operations between copper wires are realized by cold pressure welding, etc., and there are the following problems: whether it is cold pressure welding or other existing copper wire joint welding methods, it will inevitably damage the copper wires. Tin plating at the joints leads to copper exposure; in subsequent further drawing operations, the length of exposed copper will increase with the number of drawing passes, accompanied by many quality problems such as reduced corrosion resistance of the wire body and reduced service life.
