Embodiment Construction

[0033] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0034] like figure 1 Shown is 1, a kind of bare copper tin plating process, it is characterized in that, comprises the following steps:

[0035] Step 1: Pull the busbar; put the busbar roll into the wire drawing machine to pull and feed the wire;

[0036] Step 2: Put the drawn copper wire in step 1 into the tension net of the pay-off cover, and use the gray cloth to block the...

Abstract

The invention discloses a bare copper tinning process, which comprises the following steps: step 1: pull the hard wire of the bus bar; step 2: send the drawn copper wire in the step 1 into the tension net of the pay-off cover; step 3: withdraw Furnace annealing; Step 4: The water temperature of the water tank and water tank is kept at 40-60°C, and the water temperature must be raised to above 40°C before starting up, wherein the rust remover is added in the water tank; before starting up the annealing furnace. Step 5: Set up the first flowing cotton cloth, silicone skin and six flowing cotton cloths in sequence; Step 6: Oven; Step 7: Flux pickling tank; Step 8: Tin furnace tinning: set tinning heating pool ; Step 9: Roller drawing; Step 10: Wire arranging guide wheel and wire table to take up and take up the wire. The tinning effect of the copper wire of the invention is good, the structure is stable, and the output is high.

Description

technical field [0001] The invention belongs to the field of copper wire processing, in particular to a bare copper tin plating process. Background technique [0002] Tinned copper wire is a copper wire coated with a thin layer of metal tin on the surface of the copper wire; because the tinned copper wire is relatively soft and has good electrical conductivity, it has stronger corrosion resistance and oxidation resistance than bare copper wire , can greatly extend the service life of weak current cables. At present, the process design of bare copper tinning is unreasonable and the accuracy is poor, which affects the effect and output of tinning products. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a bare copper tin plating process for the deficiencies in the current technology, which is precise in processing, safe in operation, and improves the yield and tinning effect. [0004] Technical solution: In or...
