Abstract
The invention relates to a copper flat wire processing method which comprises the following steps: extruding a copper wire blank to form an initial copper flat wire section bar blank; rolling and forming the initial copper flat wire section bar blank, performing nitrogen cooling on the initial copper flat wire section bar blank, and cooling the cooled copper flat wire section bar blank by using cooling liquid, so as to form a finished product. Bare copper wires are cooled by utilizing nitrogen, the oxidation-resistant effect is greatly improved, the rejection rate is reduced, and the cost is greatly reduced.
Description
Technical field
The present invention relates to the processing method of a kind of processing method, particularly a kind of copper strap wire.
Background technology
In bare copper wire extrusion process, humidity and the different meetings of temperature cause the oxidation of bare copper wire, affect Quality Cost.In prior art, generally adopt antioxidase to process, but this processing mode antioxidant effect is unsatisfactory, and cost is higher; In addition, affect the quality of copper cash.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pressure processing method of copper strap wire cheaply, has greatly improved oxidation resistant effect, has reduced percent defective; And the copper strap wire of the method processing conducts electricity very well, has good intensity and toughness.
The technical scheme that technical problem of the present invention adopts is:
A kind of processing method of copper strap wire, its production procedure is as follows:
A, copper cash blank form just base of copper strap wire section bar by extruding;
B, with roll forming copper strap wire section bar just base first to pass through nitrogen cooling, then undertaken coolingly by cooling fluid, form finished product and get final product.
The processing method of above-mentioned a kind of copper strap wire, wherein, described pressure 1000-1100Mpa, temperature is 600 ℃-620 ℃.
The processing method of above-mentioned a kind of copper strap wire, wherein, the flow velocity of described nitrogen is 1-3M/S, nitrogen cool time is 8-10 minute; The copper strap wire section bar just walking speed of base is 2-5M/S.
Above-mentioned a kind of copper strap wire extruding method, wherein, described cooling fluid is the mixed solution of alcohol and water, described alcohol: water=1-2:5, meter in mass ratio.
Beneficial effect of the present invention is: utilize nitrogen to carry out cooling processing to bare copper wire; undertaken cooling by nitrogen the copper strap wire under the condition of high temperature; not only can protect copper strap wire; avoid oxidized; and can make the molecule of copper strap wire inside closely knit, thereby, oxidation resistant effect greatly improved; reduced percent defective, cost reduces greatly simultaneously.
The specific embodiment
Example one:
A kind of processing method of copper strap wire forms just base of copper strap wire section bar with the copper cash blank by extruding, and pressure is 1100Mpa, and temperature reaches 600 ℃; The first base of roll forming copper strap wire section bar is first passed through nitrogen cooling, undertaken cooling by cooling fluid again, the formation finished product gets final product, the flow velocity of described nitrogen is 1M/S, the copper strap wire section bar just walking speed of base is 2M/S, nitrogen cool time is 10 minutes, cooling 10 minutes of cooling fluid, the copper strap wire section bar just walking speed of base is 2M/S, and cooling fluid is the mixed solution of alcohol and water, described alcohol: water=1:5, count in mass ratio, also can be water, preferably adopt the mixed solution of alcohol and water, can make copper strap wire again cooling fast; The copper strap wire that processes has good intensity and toughness, higher non-oxidizability, and is without impact, safe and reliable on human body, and with low cost.
Performance indications: resistivity is 0.14 ohm of millimeter
2/ rice, the bending that can stand 25000 times is not ruptured.
Example two:
A kind of processing method of copper strap wire forms just base of copper strap wire section bar with the copper cash blank by extruding, and pressure is 1500Mpa, and temperature reaches 620 ℃; The first base of roll forming copper strap wire section bar is first passed through nitrogen cooling, undertaken cooling by cooling fluid again, the formation finished product gets final product, and the flow velocity of described nitrogen is 1-3M/S, and the copper strap wire section bar just walking speed of base is 5M/S, nitrogen cool time is 8 minutes, cooling 10 minutes of cooling fluid, copper strap wire the section bar just walking speed of base are 5M/S, and cooling fluid is the mixed solution of alcohol and water, described alcohol: water=2:5, meter in mass ratio; The copper strap wire that processes has good intensity and toughness, higher non-oxidizability, and is without impact, safe and reliable on human body, and with low cost.
Performance indications: resistivity is 0.17 ohm of millimeter
2/ rice, the bending that can stand 30000 times is not ruptured.
Obviously, above-described embodiment is only for example of the present invention clearly is described, and is not to be restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present invention extended out and still are among protection scope of the present invention.
