Abstract
The invention discloses a production process for a drawn copper rod wire. The process comprises the following steps: 1) moving a produced copper rod into wire drawing equipment through a travelling trolley; 2) allowing one end of the copper rod to pass through a die in the wire drawing equipment for wire drawing, wherein the copper rod is drawn into a drawn copper rod wire with a diameter of 0.3 mm; 3) winding the drawn copper rod wire obtained in the step 2) with a coil winding machine so as to obtain a coil, wherein the rotating speed of the coil winding machine is 1200 rpm; and 4) weighing a finished product and carrying out packing and warehousing after the finished product is proved to be qualified through examination. Compared with the prior art, the invention has the following advantages: through wire drawing molding of the produced copper rod, elongation and tensile strength are improved, the utilization rate of a cable in use is guaranteed, and product quality and production efficiency are improved.
Description
?
Technical field
The present invention relates to cable production technical field, relate in particular to a kind of copper bar wire drawing production technology.
?
Background technology
The wire drawing of copper bar is to produce electric wire, enamel-covered wire, the essential blank of the copper wires such as electric wire, and copper wires is electronics, one of important foundation material that electric and communication etc. are industrial.Along with the development of world's electronics telecommunications, electric wire, the industries such as enamel-covered wire and electric wire are to the demand of the copper wires also growth of high speed, thereby the demand of drive copper wire rod is increasing, also more and more higher to its quality requirement.
How copper bar is made into the wire drawing of copper bar, and can to obtain the good wire drawing of quality be also vital.At copper bar wire drawing production industry, fail to solve well.
Summary of the invention
In order to overcome above shortcomings part in prior art, the object of the present invention is to provide a kind of quality of product and copper bar wire drawing production technology of production efficiency of improving.
In order to reach above-mentioned object, the present invention adopts following concrete technical scheme: copper bar wire drawing production technology, comprises the steps:
1) first the copper bar after producing is moved in wire-drawing equipment by driving;
2) wire drawing is carried out to through mould in wire-drawing equipment in one end of copper bar, it is the copper bar wire drawing of 0.3mm that wire drawing becomes diameter;
3) then step 2) wire drawing of gained copper bar is through coil winding machine coiling lopping, and the rotating speed of coil winding machine is 1200 revs/min;
4) finally weigh product inspection qualified after, packaging and warehousing.
The present invention's advantage is compared with prior art: the present invention, by the copper bar wire-drawing shape after producing, improves percentage elongation and tensile strength, and assurance cable is increased operation rate in use procedure, improves quality and the production efficiency of product simultaneously.
The specific embodiment
By the embodiment of the present invention given below, can further understand basis bright, but protection of the present invention is not limited to this.
Embodiment: copper bar wire drawing production technology, comprises the steps:
1) first the copper bar after producing is moved in wire-drawing equipment by driving;
2) wire drawing is carried out to through mould in wire-drawing equipment in one end of copper bar, it is the copper bar wire drawing of 0.3mm that wire drawing becomes diameter, because mould molding bore dia is less than copper bar raw material diameter, by coil winding machine coiling, be there is a pulling force in copper bar, pulling force can be pulled out copper bar from mould molding hole, make copper bar extend diameter and diminish;
3) then step 2) wire drawing of gained copper bar is through coil winding machine coiling lopping, and the rotating speed of coil winding machine is 1200 revs/min;
4) finally weigh product inspection qualified after, packaging and warehousing.
Above are only a specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should belong to the behavior of invading protection domain of the present invention.
