Description

Technical Field

[0001] The invention relates to the field of cable manufacturing equipment, in particular to a cooling and cleaning device for aluminum alloy cable stranding equipment. Background Art

[0002] Aluminum alloy cable strands are wires made of aluminum alloy materials, usually used for power transmission and distribution. Aluminum alloy cable strands have good electrical conductivity, thermal conductivity, corrosion resistance, and are relatively light, so they are widely used. Aluminum alloy cable strands are usually produced using corresponding stranding machines, which are a processing equipment such as twisted ropes, which can twist several ropes such as metal aluminum alloy wires into one strand to obtain the corresponding cable.

[0003] When using a wire twisting machine for processing, since the thermal conductivity of aluminum alloy itself is worse than that of copper used in traditional cables, when multiple aluminum alloy wires enter the mold and are twisted together, the temperature of the mold will rise rapidly, and these aluminum alloy wires will rub against each other, thereby generating some aluminum chips. Or, when there is metal waste slag or other stains on the surface of a single aluminum alloy wire produced by several previous processes, even if there is no aluminum chips left over from long-term twisting processing in the forming mold, the aluminum chips and waste slag brought by the previous processes will enter the twisting mold, resulting in a rough surface of the twisted aluminum alloy cable, or the aluminum alloy cable is not formed with sufficient roundness and is severely deformed, or even direct local damage or several aluminum alloy wires break. On the other hand, after all aluminum alloy wires are twisted into bundles and become cables, aluminum alloy chips and other residues will be produced due to extrusion and friction in the twisting die. After coming out of the twisting die, the formed aluminum alloy cable bundle also needs to be cleaned, otherwise it is very easy to scratch the insulation layer during subsequent processing and use, or when used as a bare wire, the formed cable bundle will be further scratched during the winding process. Therefore, when processing aluminum alloy cable strands, they must be cleaned more thoroughly to ensure that the final twisted cable has stable quality and is safe and reliable to use.

[0004] Based on the applicant's own experience and the search and analysis of the prior art, it is concluded that there are currently two main methods for cleaning aluminum alloy cable stranding machines. First, use a spray cleaning liquid to rinse or wash each aluminum alloy wire to ensure that it remains relatively clean before entering the stranded cable forming mold. The second is to directly use wind blowing to clean it. Furthermore, the two aforementioned methods are superimposed. For example, the cooling and cleaning device for aluminum alloy cable stranding equipment with publication number CN201620001389.6 retrieved by the applicant, and the cooling and cleaning device for alloy cable stranding equipment with publication number CN206981455U based on the improved cooling and cleaning device, are carried out by the above two existing methods. Among them, for the existing cleaning equipment with publication number CN201620001389.6, the applicant believes that it is relatively reasonable and can be used to clean a single aluminum alloy wire. However, the direct oil dripping method has a very limited cleaning effect. First, the amount of dripping liquid is limited and is not enough to remove the residue on the surface. Second, the lubricating liquid itself still has a certain viscosity, and it will be contaminated with some dust and debris, thereby causing secondary pollution adhesion. Finally, before the aluminum alloy wire enters the stranding mold, there may still be a lot of pollutants including but not limited to aluminum alloy slag, which will damage the module and affect the cable forming quality. Although a purging and cleaning mechanism was added later, the aluminum slag and other pollutants contained in the one-pound formed cable could no longer be blown out, and it could only clean the surface to a certain extent, which was a temporary solution and not a fundamental solution.

[0005] As for the aforementioned cooling and cleaning device for alloy cable stranding equipment with publication number CN206981455U, the applicant believes that the ultrasonic cleaning effect is naturally better than oil dripping to clean a single aluminum alloy wire. However, there is a very big defect in the prior art, that is, the technical solution is unclear and does not take into account how these aluminum alloy wires pass through the ultrasonic cleaning machine. It lacks specificity and feasibility, and it is difficult for technical personnel in this field to implement it. Rather than being a cleaning device for an aluminum alloy cable stranding machine, it is better to say that it is an ordinary ultrasonic cleaning device that can be used universally.

[0006] In summary, the applicant believes that, based on the applicant's personal production practice experience and extensive research on the existing technology, there is currently no truly feasible cleaning equipment for aluminum alloy cable stranding equipment with good cleaning and cooling effects. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a cooling and cleaning device for aluminum alloy cable strands to solve the problem that there is currently no truly feasible cleaning device with good cleaning and cooling effects in the production process of aluminum alloy cable strands.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cooling and cleaning device for aluminum alloy cable stranding equipment, comprising an air-cooled cleaning component installed in front of the inlet end of the stranding mold for cleaning and cooling each aluminum alloy wire, the air-cooled cleaning component can blow cooling air toward the multiple aluminum alloy wires located in the center thereof, and the air-cooled cleaning component can move horizontally in a direction approaching or away from the inlet end of the stranding mold.

[0009] Furthermore, the air-cooled cleaning component includes a circular air supply duct, the inner side of which is provided with a plurality of air jet holes. The air supply duct is installed with an electric push rod to achieve horizontal movement in a direction toward or away from the inlet end of the stranding die.

[0010] Furthermore, the air-cooled cleaning component includes a section of annular elastic air pipe, a plurality of air injection holes are provided on the inner side of the elastic air pipe, and a sliding shoe is tightly fixed to the inner wall of the elastic air pipe. The sliding shoe has a tile-like structure and can just fit on the surface of the corresponding aluminum alloy wire and be axially slidably connected thereto. The elastic air pipe is horizontally moved in a direction approaching or away from the inlet end of the stranding mold through an electric push rod, and during the horizontal movement of the elastic air pipe, the elastic contraction force of the elastic air pipe ensures that each sliding shoe always maintains an effective axial sliding fit with the aluminum alloy wire it cooperates with.

[0011] Furthermore, the air-cooled cleaning component includes an annular mounting frame, and a plurality of straight jet tubes are fixedly connected to the inner area of ​​the annular mounting frame through a telescopic rod. The straight jet tube is provided with an air jet slit along its length direction on one side facing the aluminum alloy wire, so that all the aluminum alloy wires are located in the center of a polygonal wind curtain; two adjacent straight jet tubes always maintain contact with each other and are connected to each other at the contact end.

[0012] Furthermore, in two adjacent straight jet pipes, one end face of the first straight jet pipe is an inclined surface, and the inclined surface is slidably fitted on the side face of the second straight jet pipe, and a vent hole is provided on the inclined surface, and the vent hole can be connected to the jet slit on the side face of the second straight jet pipe.

[0013] Furthermore, the straight jet pipes are all elastic telescopic pipes comprising a bell pipe and a plug pipe, one end of the plug pipe is axially slidably inserted into the bell pipe and installed in the bell pipe through a pressure spring, and when the inclined surface is tightly attached to the side surface of the second straight jet pipe, the pressure spring is always in a compressed state, and the bell pipe is fixedly connected to the corresponding telescopic rod.

[0014] Furthermore, a valve column is elastically slidably installed inside the sliding fit of the inclined surface of the second jet straight pipe and the first jet straight pipe through a return spring, and when the valve column slides linearly along the jet slit in the second jet straight pipe section, the corresponding jet slit section can be blocked; A sliding pin is also fixed on the inclined surface of the first jet straight pipe, and the sliding pin is slidably installed in the jet gap of the second jet straight pipe opposite thereto. When the jet straight pipe gradually moves away from the aluminum alloy wire along the diameter direction of the annular mounting frame, the sliding pin pushes the end of the valve column to compress the return spring.

[0015] Furthermore, one of the telescopic rods can be actively telescoped, and all other telescopic rods can be axially elastically telescoped.

[0016] Furthermore, a finished cleaning component for cooling and cleaning the cables twisted into bundles is installed behind the outlet end of the stranding die, and the finished cleaning component includes a telescopic column fixed on the stranding die, and a first-level cooling element is fixed on the telescopic end of the telescopic column, and the first-level cooling element includes a first cover body coaxially sleeved outside the cable, and the front end of the axial hole with clearance fit between the first cover body and the cable is a trumpet hole, and a plurality of slag removal strips are radially elastically and telescopically installed on the inner wall at the small end of the trumpet hole, and all the slag removal strips are in an annular array and the formed circular ring structure just embraces the cable, and the slag on the cable is blocked by the slag removal strips, and then overflows forward after being accumulated in the trumpet hole; Both the front and rear ends of the first cover body are provided with a jet cavity connected to a compressed air source, and the jet cavity is a conical structure so that the conical air curtain ejected from the jet cavity can pass through the cable.

[0017] Furthermore, it also includes a second cover body which is axially slidably mounted on the horizontally straightened cable, the second cover body is horizontally elastically telescopically connected to the first cover body, a circular slag removal ring is embedded in the front end of the second cover body, the slag removal ring is sleeved on the cable, the inner wall of the slag removal ring is tangent to the cable surface, and a plurality of slag removal channels are arranged along the axial direction at the rear end of the slag removal ring, each slag removal channel is a gradually enlarged variable diameter hole structure, and the smallest end of the slag removal channel is located at the junction with the cable surface; The wind energy ejected from at least one jet chamber at the rear end of the first cover body can blow onto the second cover body, so that when the compressed air source supplies air to the first cover body, the second cover body swings back and forth along the cable relative to the first cover body under the elastic telescopic force to scrape off the remaining debris on the cable.

[0018] The present invention provides a cooling and cleaning device for aluminum alloy cable stranding equipment, which has the following beneficial effects: 1. The residue on the surface of each strand of aluminum alloy wire can be cleaned before entering the stranding die. On the one hand, it can avoid entering the stranding die and affecting the stranding into cable. On the other hand, it can also cool the aluminum alloy wire itself to avoid friction and heat generation with the corresponding conveying components during transportation, which may cause the debris attached to the surface to be thermally bonded to the aluminum alloy wire, resulting in failure to strand into cable normally.

[0019] 2. The air-cooled clean parts can move accordingly according to the expansion and contraction before the aluminum alloy wires converge, flexibly changing the distance between the jet holes or jet seams and the aluminum alloy wires, and ensuring a relatively consistent jet effect everywhere with a constant jet pressure.

[0020] 3. In addition, the present invention provides a cleaning and cooling process for each aluminum alloy wire of the aluminum alloy cable before and after twisting, so that the aluminum alloy wire entering the twisting mold can avoid the adhesion of slag pollutants, and the temperature is reduced to prevent metal debris from being hot-bonded and fixed on the surface of the aluminum alloy wire and unable to be blown off by the wind, and the wire can enter the twisting mold at a suitable temperature to ensure the twisting quality. After twisting, it is cleaned and cooled again, so that after being bundled into a cable, the slag and debris are removed and the surface is kept smooth, so as to facilitate the final covering and forming of the insulation layer.

DETAILED DESCRIPTION

[0023] This specification will clearly and completely express the technical solutions in the following examples based on the drawings of the embodiments of the present invention. The implementation methods described in this specification are only some of the embodiments of the present invention, not all of them. All other embodiments extended and inspired by those skilled in the art based on these embodiments in this application without creative work should fall within the scope of protection of the present invention.

[0024] like Figure 1 As shown, the present embodiment provides a cooling and cleaning device for aluminum alloy cable stranding equipment, including an air-cooled cleaning component 5 installed in front of the inlet end of the stranding die 7 for cleaning and cooling each aluminum alloy wire 2. Specifically, after the multiple strands of aluminum alloy wires 2 for stranding cables are divided by the branching disk 1, they are concentrated in one place and enter the stranding die, and this special air-cooled cleaning component 5 is capable of blowing cooling air towards the multiple strands of aluminum alloy wires 2 located in the center of the air-cooled cleaning component 5. That is, when these aluminum alloy wires 2 pass through the air-cooled cleaning component 5 at the same time, they will be quickly cooled down due to the blowing of the cooling air, so as to avoid the adhesion of aluminum alloy slag or even the melting on the aluminum alloy wire 2 due to overheating. At the same time, the blowing of the cooling air also blows away the slag on the surface to a large extent, avoiding adhesion. At the same time, in order to cool and clean the aluminum alloy wire 2 more thoroughly, the air-cooled cleaning component 5 in the present embodiment can also move in the direction of horizontally approaching or moving away from the inlet end of the stranding die 7, that is, it moves back and forth along the horizontal axis surrounded by the aluminum alloy wires 2, so as to improve the cooling and cleaning capabilities.

[0025] As one of the implementation structures, the air-cooled cleaning component 5 includes a circular air supply duct, and a plurality of air jet holes are provided on the inner side of the air supply duct. The air supply duct can realize horizontal movement in the direction of approaching or moving away from the inlet end of the stranding mold 7 through the installation of the electric push rod 6.

[0026] As a second implementation structure, the air-cooled cleaning component 5 includes a section of annular elastic air tube 3, and a plurality of air injection holes are provided inside the elastic air tube 3, and as shown in FIG. Figure 2-3 The inner wall of the elastic air tube 3 is also tightly fixed with a sliding shoe 4, which is a tile-like structure, or a small-petal tube structure, and can just fit on the surface of the corresponding aluminum alloy wire 2 and be axially slidably connected thereto. The elastic air tube 3 is moved horizontally in the direction of approaching or moving away from the inlet end of the stranding die 7 through an electric push rod 6, and during the horizontal movement of the elastic air tube 3, the elastic contraction force of the elastic air tube 3 enables each sliding shoe 4 to always maintain an effective axial sliding fit with the aluminum alloy wire 2 it cooperates with, so as to ensure stable movement when cooling and cleaning the aluminum alloy wire 2, especially the axial sliding fit between the sliding shoe 4 and the aluminum alloy wire 2, which can effectively scrape off the residue on the surface of the aluminum alloy wire 2, and has a better cleaning effect than simple wind blowing.

[0027] As the third implementation structure, the air-cooled cleaning component 5 has a very efficient cooling and cleaning capability, and can dynamically adjust the distance from each aluminum alloy wire 2 before the aluminum alloy wires 2 are bundled into cables, thereby fully improving the cooling and cleaning effect; it can even maintain the consistency of the blowing distance at each location when necessary. Specifically, Figure 4 , mainly comprising an annular mounting frame, in the inner area of ​​which a plurality of jet straight pipes are fixedly connected through a telescopic rod 9, that is, all jet straight pipes can spray airflow for cooling and cleaning. Specifically, on the side of the jet straight pipe facing the aluminum alloy wire 2, an air jet slit 14 is opened along its length direction, so that all the aluminum alloy wires 2 are in the center of a polygonal air curtain, and the aluminum alloy wires 2 are fully cleaned and cooled, and two adjacent jet straight pipes are always in contact, so that the polygonal air curtain is always in a closed state, and are connected to each other at the contact end, so that the polygonal air curtain can be formed by only inputting airflow into one of the jet straight pipes.

[0028] In the above implementation structure, in more detail, Figure 6 and Figure 8 As shown, in two adjacent jet straight pipes, one end face of the first jet straight pipe 8 is an inclined surface 801, and the inclined surface 801 is slidably fitted on the side of the second jet straight pipe 10, and a vent hole 16 is opened on the inclined surface 801, and the vent hole 16 can be connected to the jet slit 14 on the side of the second jet straight pipe 10, so as to realize the connection and ventilation between adjacent pipes. Figure 7 As shown, the jet straight pipe is an elastic telescopic pipe including a bell-and-spigot pipe 12 and a plug-in pipe 11. One end of the plug-in pipe 11 is axially slidably inserted into the bell-and-spigot pipe 12 and is installed in the bell-and-spigot pipe 12 through a pressure spring 13. Figure 6 As shown, when the inclined surface 801 is tightly attached to the side surface of the second jet straight pipe 10, the pressure spring 13 is always in a compressed state to ensure that the two jet straight pipes remain reliably connected and not separated, thereby ensuring the integrity of the wind curtain, and the socket pipe 12 only needs to be fixedly connected to the corresponding telescopic rod 9 to achieve installation and positioning.

[0029] Inside the sliding fit between the second jet straight pipe 10 and the inclined surface 801 of the first jet straight pipe 8, a valve column 17 is elastically slidably installed through a return spring 18. The valve column 17 can be consistent with the shape of the jet straight pipe where it is located, for example, it can be a rectangular tube structure, and is axially slidably installed in the jet straight pipe where it is located. When the valve column 17 slides linearly along the jet slit 14 in the second jet straight pipe 10 section, it can block the corresponding jet slit 14 section, that is, Figure 7 As shown, when the valve column 17 moves axially in the corresponding jet straight pipe, it can block the remaining section of the jet slot 14 near the end, thereby preventing air leakage from the remaining section and affecting the shape of the complete regular polygonal air curtain.

[0030] like Figure 8 As shown, in the present embodiment, a sliding pin 15 is particularly fixed on the inclined surface 801 of the first jet straight pipe 8, and the sliding pin 15 is slidably mounted in the jet slot 14 of the second jet straight pipe 10 opposite thereto, and when the jet straight pipe gradually moves away from the aluminum alloy wire 2 along the diameter direction of the annular mounting frame, the sliding pin 15 pushes the end of the valve column 17 so that the return spring 18 is compressed.

[0031] Due to the design of the above special structure, for adjusting the size of the polygonal air curtain, only one of the telescopic rods 9 needs to be able to actively retract, and all the other telescopic rods 9 can be able to axially elastically retract, which is very convenient.

[0032] In addition, in this embodiment, a finished cleaning component is installed after the outlet end of the stranding die 7 to cool and clean the stranded cables 24, mainly for cleaning the debris generated when passing through the stranding die 7. The finished cleaning component is specifically as follows: Figure 9-10 As shown, it includes a telescopic column 19 fixed on the stranding mold 7. If necessary, the telescopic column 19 can be axially elastic, and a first-level cooling element is fixed at the telescopic end of the telescopic column 19. The first-level cooling element includes a first cover body 20 coaxially sleeved outside the cable. The front end of the axial hole with clearance between the first cover body 20 and the cable is a trumpet hole 22. A plurality of slag strips 23 are radially elastically installed on the inner wall at the small end of the trumpet hole 22. All the slag strips 23 are in an annular array and the formed ring structure just surrounds the cable. These slag strips 23 are used to first block the larger debris on the cable, that is, the slag on the cable is blocked by the slag strips 23, and then accumulates in the trumpet hole 22, and gradually overflows or is pushed out. In addition, a jet chamber 21 connected to a compressed air source is provided in both the front and rear ends of the first cover body 20. The jet chamber 21 is a conical structure, so that the conical air curtain ejected by the jet chamber 21 can pass through the cable and fully clean the cable surface, especially the debris in the spiral groove on the cable surface.

[0033] In addition, continue to read Fig. 9The present embodiment further comprises a second cover body 25 which is axially slidably mounted on the horizontally straightened cable, the second cover body 25 is horizontally elastically telescopically connected to the first cover body 20, a circular annular slag removal ring 26 is embedded in the front end of the second cover body 25, the slag removal ring 26 is sleeved on the cable, the inner wall of the slag removal ring 26 is tangent to the cable surface, and the residue that has not been swept away by the aforementioned conical air curtain is further and more comprehensively removed, and a plurality of slag removal channels 27 are arranged along the axial direction at the rear end of the slag removal ring 26, each of which is a gradually enlarged variable diameter hole structure, and the smallest end of the slag removal channel 27 is located at the junction with the cable surface, which is conducive to the residue that is not scraped off by the slag removal ring 26 being scraped into the slag removal channel 27 at the ports of these slag removal channels 27, and then discharged.

[0034] In order to automatically realize the axial movement of the second cover body 25, as Fig. 9 The wind energy ejected from at least one jet chamber 21 at the rear end of the first cover body 20 can blow on the second cover body 25, so that when the compressed air source supplies air to the first cover body 20, the second cover body 25 swings back and forth along the cable under the elastic telescopic force relative to the first cover body 20 to scrape off the remaining slag on the cable. It is very clever. Through this elastic telescopic movement, combined with the slag discharge ring and the slag discharge channel 27, the final residual slag can be discharged, and a cable with a clean and slag-free surface can be obtained to the greatest extent, so as to facilitate the subsequent insulation rubber coating molding of the outer side of the cable and improve the quality of the finished aluminum alloy cable.

[0035] It should be explained here that, in this specification, terms such as first and second are only used to distinguish one feature from another, and do not mean that there is a certain relationship or order between these technical features. The terms "including" and "comprising" refer to the inclusion of one or some technical means or features, specifically meaning that there are other existing or non-existing technical features that have not been included. The discussion in the above embodiments is only a representative example for the present invention, and is by no means the only restrictive constraint feature. A person of ordinary skill in the art should understand that, without departing from the technical content recorded in all the claims of this application, some simple substitutions and modifications can be made, thereby changing or becoming equivalent to other specific embodiments and application scenarios. However, no matter how the adaptability is changed, these embodiments will inevitably fall within the scope of protection of the present invention.
