Abstract

The invention relates to a continuous pickling and wiredrawing process of a brass wire, which is characterized in that: after being drawn out of a wire releasing disc, a brass wire blank is subjected to continuous processes of pickling, neutralizing, brushing, cleaning and wiredrawing. A continuous producing mode is used for connecting the pickling process and the drawing process of the brass wire together, namely that after an annealed brass wire blank is arranged on a wire releasing frame by one end of a production line, a finished product of the fine-drawn brass wire can be generated from the other end, therefore, the continuous producing mode has few processing and flowing processes and stops scrapes and compression injuries in the flowing process; pickled products are wiredrawn in a shorter period to ensure better brightness and consistency of product appearance and obviously increase the surface quality of the finished product of the brass wire; the processing process has high automation degree, reduces labor intensity of staffs and increases production efficiency; when the brass wire is in the pickling process, an oxide layer on the surface of the brass wire only needs to be loosened; and therefore, when the brass wire is pickled, nitric acid does not need to be added, the usage amount of acid liquor is greatly reduced, and the production cost is reduced.

Description

technical field

[0001] The invention relates to a continuous process of pickling and wire drawing of metal wires, in particular to a continuous process of pickling and wire drawing of brass wires. Background technique

[0002] In traditional brass wire production, pickling and wire drawing are not continuous. Its production process is: first anneal the formed whole roll of brass wire, lift it to the trolley by a crane, transport it to the pickling tank, and put it into the pickling tank. Soak in the water, then run to the washing tank for washing with water, then run to the neutralization tank for emulsion protection and neutralization, and finally transport it to the wire drawing machine for drawing. The entire operation process is scattered and the production efficiency is low; the products are easy to be crushed and scratched during processing and circulation; moreover, a large amount of waste liquid and harmful gas are generated to pollute the environment, increasing the...

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, the annealed brass wire blank 7 is placed on the pay-off reel 1, and the brass wire blank 7 is manually passed through the pickling roller 22 in the pickling tank 2. During the threading process, the brass wire blank 7 is The copper wire blank 7 is wound in the wedge-shaped groove 23 of two pickling rollers 22, and then the wire blank 7 passes through the neutralization tank 3, the tensioner 4, the scrubbing tank 5, the cleaning tank 6, and then passes through the wire drawing die 8 , wind up on the wire drawing roller 9, open the wire drawing machine, and pull the brass wire billet to move toward the direction of the winding machine 9. Under the action of the traction force, the brass wire blank 7 on the pay-off reel 1 is drawn out and enters the pickling tank 2, which is filled with a sulfuric acid solution 21 with...
