Abstract
The invention relates to a brass wire drawing technology. The technology carried out after a brass wire blank is pulled from a pay-off reel comprises the steps of pickling, neutralization, scrubbing, secondary pickling, secondary neutralization, secondary scrubbing, cleaning and wire drawing. A core wire pickling and wire drawing combined continuous production mode adopted in the invention is characterized in that an annealed brass wire blank is put on a pay-off rack at one end of a streamline, and a finished fine brass wire can be drawn from the other end of the streamline, so the processing flow is less, scratches and crushing damages generated in the flow process are avoided; and the wire drawing of a pickled product within a short time guarantees the good brightness and the good consistency of the product appearance is guaranteed, and the surface quality of the finished brass wire is substantially improved.
Description
Technical field
The present invention relates to a kind of drawing process of brass wire.
Background technology
Traditional brass wire production process is: first by after the entire volume brass wire annealing of moulding; with crane, hang on dolly; be transported to descaling bath place; put in acid and soak; rerun and in flushed channel, carry out clear water flushing; and then run to and in neutralization chamber, carry out emulsion protection neutralization, finally transport to again the wire drawing of wire drawing machine place.Whole operating process is disperseed, and production efficiency is low; Product easily causes and weighs wounded, abrades in processing, circulation process; But also produce a large amount of waste liquids and pernicious gas contaminated environment, increased metal and other consumption of materials; Employee's operating environment is poor, working strength is large, is also prone to accident.And because entire volume material is immersed in acid solution; water directly rinses; the inner line of volume due to and together, oxide likely rushes, often can online remained on surface color spot; therefore when pickling, to add relatively large sulfuric acid; also need to add nitric acid simultaneously, just can make the oxide layer of brass wire loose at acid cleaning process and matrix, therefore; the consumption of acid is large, and pollution on the environment is also serious.Existing brass wire pickling drawing process also needs further improvement.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of drawing process of brass wire.
The drawing process of described a kind of brass wire, it is characterized in that brass wire base from draw drum pulls out through following technique:
1) pickling: be filled with pickle in descaling bath, the brass wire base that has moved back fire is wrapped on two pickling rollers and passes through descaling bath with repeatedly after-combustion form;
2) neutralization: the brass wire base through overpickling passes through in the nozzle ejection alkali lye in neutralization chamber and the pickle of brass wire base adsorption;
3) scrub: the brass wire base through alkali lye neutralization is scrubbed to dirt and the oxide on polishing brass wire base by scrubbing in groove through the wheel of scrubbing with Flexible brush;
4) white picking: be filled with pickle in descaling bath, the brass wire base of having scrubbed is wrapped on two pickling rollers and passes through descaling bath with repeatedly after-combustion form;
5) secondary neutralization: the brass wire base through overpickling passes through in the nozzle ejection alkali lye in neutralization chamber and the pickle of brass wire base adsorption;
6) secondary is scrubbed: the brass wire base through alkali lye neutralization is scrubbed to dirt and the oxide on polishing brass wire base by scrubbing in groove through the wheel of scrubbing with Flexible brush;
7) clean: by being drawn in the middle of the rinse bath that is provided with upper and lower emulsification nozzle through scrubbing the brass wire base of polishing, to brass wire base surface spray wire drawing emulsion;
8) wire drawing: the brass wire base through spray wire drawing emulsion is drawn in wire drawing machine to drawing-down to the brass wire of 1-10mm.
The drawing process of described a kind of brass wire, is characterized in that described pickle is the sulfuric acid solution of 2-15% weight.
The drawing process of described a kind of brass wire, is characterized in that described alkali lye is the NaOH solution of 1-5% weight.
The drawing process of described a kind of brass wire, is characterized in that the Negotiation speed of described brass wire base is 50-150 m/min.
The invention has the beneficial effects as follows: because the present invention is the continuous mode of production that the pickling of copper cash and wire drawing are linked together, one that is streamline the brass wire material base that has moved back fire is put after pay off rack, from other end, can go out the brass wire finished product through drawing-down, processing circulation process is few, the scratch of having stopped to produce in circulation process, weigh wounded, and the complete product of pickling carries out wire drawing in the short period of time, having guaranteed that product is apparent has a better glossy and uniformity, significantly improves brass wire finished surface quality.
The specific embodiment
A drawing process for brass wire, brass wire base from draw drum pulls out through following technique:
1) pickling: be filled with pickle in descaling bath, the brass wire base that has moved back fire is wrapped on two pickling rollers and passes through descaling bath with repeatedly after-combustion form;
2) neutralization: the brass wire base through overpickling passes through in the nozzle ejection alkali lye in neutralization chamber and the pickle of brass wire base adsorption;
3) scrub: the brass wire base through alkali lye neutralization is scrubbed to dirt and the oxide on polishing brass wire base by scrubbing in groove through the wheel of scrubbing with Flexible brush;
4) white picking: be filled with pickle in descaling bath, the brass wire base of having scrubbed is wrapped on two pickling rollers and passes through descaling bath with repeatedly after-combustion form;
5) secondary neutralization: the brass wire base through overpickling passes through in the nozzle ejection alkali lye in neutralization chamber and the pickle of brass wire base adsorption;
6) secondary is scrubbed: the brass wire base through alkali lye neutralization is scrubbed to dirt and the oxide on polishing brass wire base by scrubbing in groove through the wheel of scrubbing with Flexible brush;
7) clean: by being drawn in the middle of the rinse bath that is provided with upper and lower emulsification nozzle through scrubbing the brass wire base of polishing, to brass wire base surface spray wire drawing emulsion;
8) wire drawing: the brass wire base through spray wire drawing emulsion is drawn in wire drawing machine to drawing-down to the brass wire of 1-10mm.
Above-mentioned pickle is the sulfuric acid solution of 2-15% weight, and alkali lye is the NaOH solution of 1-5% weight, and the Negotiation speed of brass wire base is 50-150 m/min.
