Abstract
A kind of copper wire drawing process, after copper wire is pulled out from draw drum, including following 5 steps: pickling, neutralization, polishing, cleaning, wire drawing.After the copper wire material base for having moved back fire is put pay off rack, it is automatically performed production overall process, the scratch in product transport process is reduced, weighs wounded, process high degree of automation, reduce the labor intensity of employee, improve production efficiency；Copper wire, only need to be loose by the oxide layer of copper line surface in pickling process, and production cost is low.
Description
Technical field
The present invention relates to the continuous processing of metal wire rod pickling and drawing-down silk, especially a kind of copper wire drawing process.
Background technique
Copper fabrication is the important component of China's non-ferrous metals industry.By the fast development of many years, China at
It is remarkably reinforced for the maximum copper material producing country in the whole world and country of consumption, comprehensive strength.In recent years, in face of complicated and changeable domestic and international macro
Economic situation and development environment are seen, Copper fabrication industry is actively pushed forward to turn mode, adjusts structure, promotees transition, and continuing for industry is maintained
It is fast-developing.Currently, copper industry working ability is constantly promoted, application field constantly expands, horizontal continuous improvement of domesticizing, entirely
Industry presents booming good situation.But simultaneously also it should be seen that, that there are still product homogeneity is serious for the whole industry, product is attached
The task of the problems such as value added lower, transition and upgrade and spanning development is urgent and arduous.
Traditional COPPER WIRES PRODUCTION, pickling and wire drawing are not continuously that its production process is: first by molding entire volume copper wire
It after annealing, is hung on trolley, is transported at descaling bath with crane, put into acid and impregnate, rerun progress clear water punching in flushed channel
It washes, then reruns and carry out emulsion protection neutralization in neutralization chamber, finally transport to wire drawing at wire drawing machine again.Whole operation stream
Journey dispersion, production efficiency are low；Product is easily caused in processing, circulation process to be weighed wounded, abrades；But also generate a large amount of waste liquid with
Pernicious gas pollutes environment, increases metal and other consumptions of materials；Employee's operating environment is poor, great work intensity, also easily occurs
Accident.And since bulk roll of material is immersed in acid solution, water is directly rinsed, the line inside volume due to and together, oxide has
May punching do not fall, often can online remained on surface color spot, therefore larger amount of sulfuric acid to be added in pickling, while also needing to be added
Nitric acid can just make the oxide layer of copper wire loose with matrix in acid cleaning process, and therefore, sour dosage is big, the dirt caused by environment
It contaminates also serious.Existing copper wire pickling drawing process also needs to be further improved.
Summary of the invention
The present invention be directed to the above-mentioned state of the art, single line continuous acid-washing is proposed, and is carried out immediately after copper wires pickling
Silk is drawn and attenuated, reaches processing and flows through that journey is few, labor intensity is low, reduce environmental pollution, the mesh to improve product quality and production efficiency
's.
A kind of copper wire drawing process, it is characterised in that copper wire from draw drum pull out after through overpickling, neutralization, polishing,
6 cleaning, wire drawing, take-up processes.
The beneficial effects of the present invention are:
Since the present invention is the continuous production mode that the pickling of copper wire and wire drawing link together, the copper wire material base of fire will have been moved back
After putting pay off rack, the copper wire finished product drawn and attenuated can be gone out, processing flows through that journey is few, reduces scratch in product transport process, pressure
Wound, process high degree of automation reduce the labor intensity of employee, improve production efficiency；Copper wire is in pickling process, only
Need to be loose by the oxide layer of copper line surface, production cost is low.
Specific embodiment
It elaborates below to the present invention.
A kind of copper wire drawing process, after copper wire is pulled out from draw drum, including following 6 steps: pickling, neutralization, throwing
Light, cleaning, wire drawing.
The pickling is that the copper wire base for having moved back fire is wrapped on two pickling rollers filled with pickling solution in descaling bath
Pass through descaling bath in the form of multiple after-combustion；
The neutralization is the acid that the copper wire through overpickling sprays that in lye and copper line surface is adsorbed by the nozzle in neutralization chamber
Washing lotion；
Described is finished to the copper wire neutralized by lye by scrubbing in wash tank by the wheel of scrubbing with Flexible brush
Polish the dirt and oxide on copper wire；
The cleaning is that will be drawn among the rinse bath equipped with upper emulsified nozzle by the copper wire of polishing, to copper line surface
Spray wire drawing lotion；
The take-up is that two groups of take-up reels alternately coil copper wire after molding.
After the copper wire material for having moved back fire is put pay off rack, it is automatically performed production overall process, is reduced in product transport process
It abrades, weigh wounded, process high degree of automation reduces the labor intensity of employee, improves production efficiency；Copper wire is in pickling work
, only need to be loose by the oxide layer of copper line surface when sequence, production cost is low.
The pickling solution is the sulfuric acid solution of 5% concentration, pickling solution depth 15-18cm.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements accordingly, and protection of the invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
