Description

Enameled wire drawing process and equipment

technical field

The invention relates to enameled wire production equipment, in particular to a process and equipment for enameled wire drawing.

Background technique

The enameled wire needs to be drawn during the production process. In the process of the enameled wire being thickened and thinned, the law of metal extension must be followed: due to the slip and change of the internal lattice of the metal during stretching. The mechanical properties of the wire change, the hardness becomes harder, and the elongation decreases. Therefore, the diameter of one stretch cannot be too different, otherwise the wire will be broken.

The prior art wire drawing machine structure and wire drawing process as shown in Fig. 1 and Fig. 2:

The structure of the original wire drawing machine mainly consists of a wire-drawing mechanism (a wire reel, a guide wheel, etc.), a wire-drawing mechanism (servo motor, a tower pulley, a cooling mechanism, etc.), and a wire-receiving mechanism.

The production process is:

As shown in Figure 1, on the first wire drawing machine, the copper wire 191 of 0.4mm is introduced from the pay-off reel 11 through the guide wheel 12, into the tower wheel box 13, and bypasses several tower wheels in the tower wheel box 13, such as four After the tower pulleys 131, 132, 133, 134, pull from the first-stage copper wire 191 of 0.4mm to the second-stage copper wire 192 of 0.16mm, pass through the guide pulley 14, the tension pulley 15, and wind up on the take-up pulley 16 . Put the take-up reel 16 on the pay-off reel 11 of the second wire drawing machine again, the second-stage copper wire 192 of 0.16mm passes through the guide pulley 12 from the pay-off reel 11, introduces the tower wheel box 13, and walks around the tower wheel After the four tower pulleys 131, 132, 133, 134 in the case 13, the second-stage copper wire 192 of 0.16mm is drawn to the third-stage copper wire 193 of 0.05mm, through the guide pulley 14, the tension pulley 15, around onto the take-up reel 16.

It is also possible to change a complete set of molds on the first wire drawing machine, and then draw the copper wire from 0.16mm to 0.05mm.

The disadvantage of the above-mentioned prior art is that the wire reel needs to be unwound twice and taken up twice, which wastes labor and energy, and the production efficiency is low.

Contents of the invention

The invention provides an enameled wire drawing process and equipment, and its purpose is to solve the shortcomings of the prior art, save energy and improve production efficiency.

The technical solution adopted by the present invention to solve its technical problems is:

Enameled wire drawing equipment is characterized in that:

There are pay-off reels, guide wheels, the first tower wheel box, the first fixed speed wheel, the second tower wheel box, and the second fixed speed wheel in sequence; the first tower wheel box is equipped with a first tower wheel composed of two tower wheels. Drawing die, the second tower wheel box is equipped with a second wire drawing die composed of multiple tower wheels, the copper wire is introduced into the first tower wheel box after passing through the pay-off reel and guide wheel, and is repeatedly wound back and forth in the first tower wheel box The first tower wheel box is drawn out from the two tower wheels, and then the second tower wheel box is introduced through the first fixed speed wheel, and then wound on the four tower wheels in the second tower wheel box in turn, leading to the second tower Wheel box, past the second fixed speed wheel.

The number of cone wheels of the second wire drawing die is greater than the number of cone wheels of the first wire drawing die.

The enameled wire drawing process is characterized in that: the 0.4mm copper wire is introduced into the first tower wheel box, drawn from 0.4mm to 0.16mm by the first wire drawing die, introduced into the second tower wheel box, and drawn from 0.16mm to 0.16mm by the second wire drawing die 0.05mm.

The benefits of the present invention are:

The present invention installs two sets of drawing dies on a wire drawing machine, the first set of dies draws the copper wire from 0.4mm to 0.16mm, and immediately introduces the second set of dies to draw the copper wire from 0.16mm to 0.05mm. Therefore, on a wire drawing machine, two sets of molds are used to draw the copper wire from 0.4mm to 0.16mm. After the wire drawing is completed, it is immediately introduced into the enamelling machine for painting and drying. Paying off, drawing, taking up, and painting are carried out continuously at one time, which saves labor, saves energy, improves product quality, and improves production efficiency.

Detailed ways

In order to illustrate the technical solution of the present invention more clearly, the accompanying drawings that need to be used in the description will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. As far as people are concerned, other embodiments can also be obtained according to these drawings on the premise of not paying creative work.

As shown in Figure 3:

The present invention is provided with pay-off reel 1 successively, guide wheel 2, the first tower wheel box 3 (the first wire drawing die that tower wheel 31, tower wheel 32 are formed in the first tower wheel box 3), the first fixed speed wheel 5, the second cone wheel box 4 (the second cone wheel box 4 is provided with the second wire drawing die formed by the cone wheel 41, the cone wheel 42, the cone wheel 43, and the cone wheel 44), the second constant speed wheel 6.

The 0.4mm first-stage copper wire 191 is introduced into the first tower wheel box 3 after passing through the pay-off reel 1 and the guide wheel 2, and is repeatedly wound back and forth on the two tower wheels 31 and 32 in the first tower wheel box 3 , drawn by the first wire drawing die from the first-stage copper wire of 0.4mm to the second-stage copper wire 192 of 0.16mm, leading out of the first tower wheel box 3, passing through the first fixed speed wheel 5, and then introducing the second tower wheel box 4. Wind around the tower wheel 41, tower wheel 42, tower wheel 43, and tower wheel 44 in the second tower wheel box 5 in turn, and be drawn from the second-stage copper wire 192 of 0.16mm to 0.05mm by the second wire drawing die The copper wire 193 of the third stage leads out the second tower wheel box 4, passes through the second fixed speed wheel 6, and the wire drawing finishes, and immediately goes out to the enamelling machine for painting and drying.

The first fixed speed wheel 5 and the second fixed speed wheel 6 play the role of constant speed, so that the copper wire advances at a uniform and stable speed.

Since the thickness of the wire in the transition process from the first-stage copper wire 191 to the second-stage copper wire 192 is greater than the thickness of the wire in the transition process from the second-stage copper wire 192 to the third-stage copper wire 193, it is repeatedly wound back and forth at the first stage. On two tower wheels 31, the tower wheel 32 in a tower wheel case 3, strengthen the frictional force of copper wire and tower wheel, reduce slipping. The number of cones of the second wire drawing die can be greater than 4 and more than the number of cones of the first wire drawing die.
