Description

Enameled wire drawing equipment

Technical Field

The utility model relates to an enameled wire production facility, specifically speaking are equipment for enameled wire drawing.

Background

The enameled wire needs to be subjected to wire drawing in the production process, and the metal extension rule is followed in the process that the diameter of the enameled wire is roughly drawn: during stretching, the internal crystal lattice of the metal slips and changes. The mechanical property of the lead is changed, the hardness is hardened, and the elongation is reduced. The primary drawing diameter cannot differ too much, otherwise the wire will be pulled apart.

The structure and the drawing process of the drawing machine in the prior art as shown in fig. 1 and 2 are as follows:

the original structure of the wire drawing machine mainly comprises a wire releasing mechanism (a wire releasing disc, a guide wheel and the like), a wire drawing mechanism (a servo motor, a cone pulley, a cooling mechanism and the like), a wire winding mechanism and the like.

The manufacturing process comprises the following steps:

referring to fig. 1, a 0.4mm copper wire 191 is first drawn from a pay-off reel 11 through a guide pulley 12, introduced into a step pulley box 13, and then passed around a plurality of step pulleys, e.g., four

step pulleys

131, 132, 133, and 134, in the step pulley box 13, and then drawn from a 0.4mm first-stage copper wire 191 to a 0.16mm second-stage copper wire 192, which is then passed through a guide pulley 14 and a tension pulley 15, and then wound around a take-up pulley 16. And then the take-up pulley 16 is placed on the pay-off reel 11 of the second wire drawing machine, the 0.16mm second-stage copper wire 192 is led into the cone pulley box 13 from the pay-off reel 11 through the guide pulley 12, and after bypassing the four

cone pulleys

131, 132, 133 and 134 in the cone pulley box 13, the 0.16mm second-stage copper wire 192 is pulled to the 0.05mm third-stage copper wire 193, passes through the guide pulley 14 and the tension pulley 15, and is wound on the take-up pulley 16.

Or the whole set of dies can be replaced on the first wire drawing machine, and the copper wire is drawn from 0.16mm to 0.05 mm.

The defects of the prior art are that the wire disc needs secondary paying off and secondary winding up, which wastes labor and energy and has low production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model provides an enameled wire drawing process and equipment, its purpose is to solve prior art's shortcoming, and the energy saving improves production efficiency.

The utility model provides a technical scheme that its technical problem adopted is:

enameled wire drawing equipment, its characterized in that:

the device is sequentially provided with a pay-off reel, a guide wheel, a first tower wheel box, a first constant speed wheel, a second tower wheel box and a second constant speed wheel; the first drawing die that two cone pulleys are constituteed is equipped with in the first cone pulley incasement, the second drawing die that a plurality of cone pulleys are constituteed is equipped with in the second cone pulley incasement, and copper conductor leads into first tower wheel case behind drawing drum, guide pulley, makes a round trip to draw forth first tower wheel case on locating two cone pulleys in the first tower wheel case repeatedly, through first constant velocity pulley, reintroduce the second tower wheel case, in proper order around locating four cone pulleys in the second tower wheel case, draw forth second tower wheel case, through second constant velocity pulley.

The number of the step pulley of the second wire-drawing die is larger than that of the first wire-drawing die.

A 0.4mm copper wire is introduced into a first turret-type box and drawn from 0.4mm to 0.16mm by a first drawing die, introduced into a second turret-type box and drawn from 0.16mm to 0.05mm by a second drawing die.

The utility model discloses an useful part lies in:

the utility model discloses at a wire drawing machine facial make-up two drawing dies, first set of mould draws the copper conductor to 0.16mm from 0.4mm, introduces second set of mould at once, draws the copper conductor to 0.05mm from 0.16 mm. Therefore, on one wire drawing machine, two sets of dies are used for drawing the copper wire from 0.4mm to 0.16mm, and after wire drawing is finished, an enamelling machine is immediately introduced for painting and drying. The paying-off, the wire drawing, the wire winding and the painting are continuously carried out at one time, so that the labor and the energy are saved, the product quality is improved, and the production efficiency is improved.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic view of a first drawing machine of the prior art;

FIG. 2 is a schematic view of a second drawing machine of the prior art;

fig. 3 is a schematic view of the present invention.

Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.

As shown in fig. 3:

the utility model discloses be equipped with drawing drum 1 in proper order, guide pulley 2, first tower wheel case 3 (be equipped with the first drawing die that cone pulley 31, cone pulley 32 are constituteed in the first tower wheel case 3), first flywheel 5, second tower wheel case 4 (be equipped with the second drawing die that cone pulley 41, cone pulley 42, cone pulley 43, cone pulley 44 are constituteed in the second tower wheel case 4), second flywheel 6.

The 0.4mm first-stage copper wire 191 is led into the first tower wheel box 3 after passing through the pay-off reel 1 and the guide wheel 2, repeatedly wound on the two

cone pulleys

31 and 32 in the first tower wheel box 3 back and forth, pulled from the 0.4mm first-stage copper wire to the 0.16mm second-stage copper wire 192 by the first wire drawing die, led out of the first tower wheel box 3, passed through the first fixed speed wheel 5, led into the second tower wheel box 4, sequentially wound on the cone pulley 41, the cone pulley 42, the cone pulley 43 and the cone pulley 44 in the second tower wheel box 5, pulled from the 0.16mm second-stage copper wire 192 to the 0.05mm third-stage copper wire 193 by the second wire drawing die, led out of the second tower wheel box 4, passed through the second fixed speed wheel 6, the wire drawing is finished, and the wire is immediately led out to an enamelling machine and dried.

The first constant speed wheel 5 and the second constant speed wheel 6 play a constant speed role, so that the copper conducting wire can advance at a uniform and stable speed.

Because the thickness of the transition process lead from the first-stage copper lead 191 to the second-stage copper lead 192 is greater than that of the transition process lead from the second-stage copper lead 192 to the third-stage copper lead 193, the copper lead repeatedly winds the two

cone pulleys
