As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
Some embodiments of the present application are described in detail. In the following embodiments, features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, some metal wires having inner and outer layers of different metals, such as an aluminum layer coated on the outer layer of a steel core, are used to conduct electric current, and the physicochemical properties of the wire are improved by the coating layer.
To produce aluminum-clad steel wire, a common approach is to first compound an aluminum rod on metal steel by an extrusion cladding technique to produce an aluminum-clad steel busbar. After the extrusion coating process is finished, synchronously drawing two metals of aluminum and steel in the aluminum-clad steel bus through a wire drawing process. In the drawing process of the known drawing equipment, the aluminum layer of a partial area of the aluminum-clad steel bus is scratched, even the steel core is exposed, the problem that the coaxiality of the aluminum layer of the drawn aluminum-clad steel wire and the steel core is low exists, and the exposed aluminum layer of the steel core is scratched, so that the aluminum-clad steel wire is easier to corrode in the area, and the service life of the aluminum-clad steel wire is shortened.
The pressure die and the wire drawing die of traditional drawing equipment are the cooperation structure that the tip supported usually, and operating personnel need hard with wire drawing die and pressure die top tightly to guarantee that the mould combines closely, and then guarantee that the axis of aluminium package steel generating line flushes with the axis of the through-hole of mould. However, the known matching between the pressure die and the wire-drawing die has errors, or errors are easily generated when the stress is uneven, so that the axes of the through holes of the pressure die and the wire-drawing die cannot be overlapped easily, and then the axes are difficult to be overlapped with the axis of the aluminum-clad steel bus, so that the stress of the aluminum layer in the partial area of the aluminum-clad steel bus is uneven in the drawing process, and the problems of scratching or exposure are further generated.
Examples
Referring to fig. 2, the present embodiment provides an apparatus 100 for improving the coaxiality of aluminum alloy clad steel wires, which is used for drawing an aluminum clad steel bus 600, and the apparatus 100 for improving the coaxiality of aluminum alloy clad steel wires comprises a pressure die 10, a wire-drawing die 20 and a fixing sleeve 30. The pressure die 10 defines a pressure channel 11, and the pressure channel 11 is used for pressing the fine aluminum-clad steel busbar 600 and forming the aluminum-clad steel wire 500. The drawing die 20 defines a drawing passage 21 for allowing the aluminum-clad steel wire 500 to pass through. The fixing sleeve 30 is sleeved on the wire-drawing die 20 and the pressure die 10 and is in threaded connection with the wire-drawing die 20 and the pressure die 10, so that the axis of the wire-drawing passage 21 is parallel to the axis of the pressure passage 11.
Since the fixing sleeve 30 is screwed with the wire-drawing die 20 and simultaneously with the pressure die 10, the axis of the pressure channel 11 and the axis of the fixing sleeve 30 are substantially coincident, and the axis of the wire-drawing channel 21 and the axis of the fixing sleeve 30 are substantially coincident, so that the axis of the pressure channel 11 and the axis of the wire-drawing channel 21 are substantially coincident. In the process of drawing the aluminum-clad steel bus 600 by the apparatus 100 for improving the coaxiality of the aluminum alloy-clad steel wire, the aluminum-clad steel bus 600 is subjected to a tensile force and applies a force to the pressure die 10 and the wire-drawing die 20, however, most of the force is along the axial direction of the wire-drawing channel 21 and the pressure channel 11, and very few of the force is along the axial direction obliquely intersecting the wire-drawing channel 21 and the pressure channel 11, the pressure die 10 is difficult to rotate relative to the fixing sleeve 30 under a small amount of force, and the wire-drawing die 20 is difficult to rotate relative to the fixing sleeve 30 under a small amount of force.
It can be understood that, in the known interference fit structure between the pressure die 10 and the fixing sleeve 30, the interference fit between the wire-drawing die 20 and the fixing sleeve 30, the pin tightening between the pressure die 10 and the fixing sleeve 30 by the pin, the pin tightening between the wire-drawing die 20 and the fixing sleeve 30 by the pin, and the like, in the process of drawing the aluminum-clad steel bus 600 by the device 100 for improving the coaxiality of the aluminum-clad steel wires, because the fit between the fixing sleeve 30 and the wire-drawing die 20 and the pressure die 10 is mainly a plane fit, when an acting force is applied, relative displacement is relatively easily generated, and further, the axis of the wire-drawing channel 21 is still staggered from the axis of the pressure channel 11.
Therefore, according to the device 100 for improving the coaxiality of the aluminum-clad steel wire in the embodiment of the application, the fixing sleeve 30 can reliably fix the pressure die 10 and the wire-drawing die 20 through the threaded connection between the pressure die 10 and the fixing sleeve 30 and the threaded connection between the wire-drawing die 20 and the fixing sleeve 30, the pressure die 10 and the wire-drawing die 20 are difficult to move relatively in the drawing process of the aluminum-clad steel bus 600, and the coaxiality of the pressure channel 11 and the wire-drawing channel 21 is improved, so that the axial line of the steel core 501, the axial line of the aluminum layer 502, the axial line of the wire-drawing channel 21 and the axial line of the pressure channel 11 are approximately overlapped in the drawing process of the aluminum-clad steel bus 600, the possibility that the steel core 501 is scratched due to uneven stress is reduced, the steel wire 501 is exposed, the drawing protection effect and the machining quality of the aluminum-clad steel wire 500 are improved, the protection effect of the aluminum layer 502 on the steel wire 501 is further ensured, and the service life of the aluminum-clad steel wire 500 is prolonged.

In the process that the aluminum-clad steel bus 600 is pulled, the aluminum-clad steel bus 600 applies acting force to the pressure die 10, the pressure die 10 applies acting force to the wire-drawing die 20, the pressure die 10 and the wire-drawing die 20 are matched with the conical surface of the conical hole 22 through the conical part 12, the acting force applied to the wire-drawing die 20 by the pressure die 10 is perpendicular to the conical surface, the acting force is decomposed into force perpendicular to the axis of the pressure channel 11 and force parallel to the axis of the pressure channel 11, the acting force applied to the wire-drawing die 20 by the pressure die 10 on the axis of the pressure channel 11 is reduced, the possibility of relative displacement of the pressure die 10, the wire-drawing die 20 and the fixing sleeve 30 is further reduced, and the coaxiality of the wire-drawing channel 21 and the pressure channel 11 is improved in the drawing process. In addition, the known wire-drawing die 20 and the pressure die 10 are usually in an end-abutting fit structure, and the pressure die 10 and the wire-drawing die 20 are prone to generate relative displacement on the axis perpendicular to the pressure channel 11, and in the embodiment of the present application, the fit of the tapered hole 22 and the tapered portion 12 is also beneficial to limiting the wire-drawing die 20 and the pressure die 10 in the direction perpendicular to the axis of the pressure channel 11, so that the possibility of generating relative displacement is reduced, and the coaxiality of the wire-drawing die 20 and the pressure die 10 is further improved.
In some embodiments, referring to FIG. 3, the taper angle of the tapered portion 12 is α,80 ≦ α ≦ 100. The component force of the wire-drawing die 20 in the direction perpendicular to the axis of the pressure channel 11 is easily increased due to the excessively large taper angle, and the tapered part 12 is thin due to the excessively small taper angle and is easily broken under a large acting force, in the embodiment, the angle alpha is more than or equal to 80 degrees and less than or equal to 100 degrees, so that the component force of the wire-drawing die 20 can be reduced, and the overall strength of the pressure die 10 can be ensured. It is understood that α can be any one of 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 degrees.

The pressure die 10 can draw the aluminum-clad steel bus 600 with a larger outer diameter into the aluminum-clad steel wire 500 with a smaller outer diameter, in the embodiment, the pressure die sleeve 13 and the pressure die core 14 are both provided with the pressure channel 11, and the pressure die core 14 completes the above drawing process, therefore, the material performance of the pressure die core 14 is higher than that of the pressure die sleeve 13, and the pressure die sleeve 13 is matched with the drawing die core 24, so that the consumables of the pressure die core 14 can be reduced, the pressure channel 11 can be directly communicated into the drawing channel 21 in the drawing die core 24, and the drawing channel 21 of the drawing die core 24 can play a better protection role on the aluminum-clad steel wire 500.
In this embodiment, a pressure straight hole 15 is formed in the pressure mold core 14, and one end of the pressure straight hole 15 away from the wire-drawing die 20 is expanded outward to form a straight counterbore 16, so as to allow the aluminum-clad steel bus 600 to penetrate into the pressure mold 10, and the wire is drawn under the action of the pressure straight hole 15 to form the aluminum-clad steel wire 500.
In this embodiment, the end of the wire drawing die sleeve 23 facing the pressure die sleeve 13 is provided with a guide counterbore 231, the wire drawing channel 21 in the wire drawing die core 24 comprises a straight wire drawing hole 25 and an arc counterbore 26 which are communicated, and the arc counterbore 26 is arranged at the end of the straight wire drawing hole 25 close to the pressure die 10 and is formed by outward expansion of the straight wire drawing hole 25. Together, pilot counterbore 231 and arcuate counterbore 26 form tapered bore 22. The taper angle of the arc-shaped counterbore 26 is beta 1, the taper angle of the guide counterbore 231 is beta 2, beta 2 is not less than beta 1, beta 1 is not less than alpha, and the guide counterbore 231 can guide the tapered part 12 so that the tapered part 12 of the pressure die sleeve 13 is accurately matched with the arc-shaped counterbore 26. As an example, in this embodiment, β 1=80 °, β 2=100 °, and α =80 °, in other embodiments of this embodiment, α, β 1, and β 2 may be set to other angles as long as the above relationship is satisfied.
