Description

Technical Field

[0001] The utility model relates to the field of cable production, in particular to a wire drawing device. Background Art

[0002] Wire drawing is a process that applies traction and shear force to metal materials to make them gradually thinner and longer. For example, the wire cores in cables are often made through metal wire drawing. A lot of heat is generated during the wire drawing process, and the metal wire may deform, crack, and have other defects due to the heat. In order to reduce the temperature of the metal wire and avoid deformation, cracks, and other problems, it needs to be cooled.

[0003] For example, the patent "A Metal Wire Drawing Cooling Device" with application number CN218963646U sprays liquid on the metal wire to cool it down through two cooling delivery pipes 4, and at the same time, the knocking head 13 swings back and forth to knock the wire rope, thereby removing water droplets on the metal wire.

[0004] First, the above device removes water from the metal wire by knocking. During the knocking process, the metal wire may be deformed due to the force, which affects the quality of the finished product. Secondly, during the metal drawing process, the metal may be deformed and produce metal debris and dust. The above device lacks a water treatment structure in the wire drawing cooling box. The coolant is in the wire drawing cooling box, and the water contains metal debris, which cannot be recycled and reused, resulting in waste. Therefore, the applicant believes that the existing technology still has room for improvement in the cooling device of the metal wire during the metal drawing process. Utility Model Content

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0039] Please combine Figure 1 - Figure 6 A wire drawing device in this embodiment includes a cleaning pool 1. First, a mounting frame 2 is fixedly welded at one end of the cleaning pool 1. A positioning plate 3 is fixedly connected to the mounting frame 2 by screws. Two positioning grooves 31 are opened on the positioning plate 3. A drawing plate 4 for drawing the metal wire is installed in the positioning groove 31.

[0040] The wire drawing plate 4 has a hole in the middle, and the metal wire needs to pass through the wire drawing plate 4. In order to meet the wire drawing needs in different situations, the diameter of the hole is different, and the size of the drawn metal wire is also different. In order to facilitate replacement, the wire drawing plate 4 is set to be replaceable.

[0041] During installation, the drawing plate 4 is directly placed into the positioning groove 31 from above. In order to prevent the drawing plate 4 from jumping, a corresponding stopper 32 is also provided on the positioning plate 3. First, the upper end surface of the stopper 32 is inclined. In addition, a spring 33 is provided on one side of the stopper 32, and a control rod 34 is fixedly connected to the upper end of the stopper 32.

[0042] A cavity is provided inside the positioning plate 3, and a part of the stopper 32 and the spring 33 are both located inside the cavity of the positioning plate 3. The upper end of the control rod 34 extends out of the positioning plate 3, and a control groove (not marked in the figure) corresponding to the control rod 34 is provided on the positioning plate 3, and the control rod 34 can move along the control groove. When the control rod 34 moves, the stopper 32 can be driven to move.

[0043] During installation, the wire drawing plate 4 is pressed downward and contacts the inclined edge of the stopper 32, which will automatically squeeze the stopper 32 into the cavity of the positioning plate 3, and the spring 33 is also squeezed. When the wire drawing plate 4 is placed, the stopper 32 extends under the action of the spring 33, and presses against the wire drawing plate 4 from above to prevent it from jumping, ensuring a smooth wire drawing process. In addition, the movement of the stopper 32 can also be controlled by the control rod 34.

[0044] Because a large amount of heat is generated during the metal wire drawing process, the metal wire may be deformed, cracked, etc. under the influence of heat. In order to avoid these problems, a circulating spray mechanism 5 is provided. In this embodiment, water is used as the coolant.

[0045] Specifically, the circulating spray structure includes two square spray pipes 52 and a fixing frame 51 for fixing the spray pipes 52, wherein the fixing frame 51 is also fixedly connected to the mounting frame 2, and two rectangular (long strip) spray pipes 52 are arranged on the fixing frame 51 along the direction of the metal wire. In addition, the spray circulation mechanism also includes a circulating water pipe 53, the upper end of the circulating water pipe 53 is connected to the spray pipe 52, and the lower end is connected to the cleaning pool 1, and in actual use, the circulating water pipe 53 also needs to cooperate with a water pump, and the water pump can be fixedly installed on the outer wall of the cleaning pool 1.

[0046] Therefore, the high-temperature metal wire after wire drawing can reduce the temperature under the spraying effect of the nozzle 52. The water sprayed by the nozzle 52 falls into the cleaning pool 1, and can be reused by the water pump and the circulating water pipe 53.

[0047] It should be noted that during the metal wire drawing process, deformation may produce metal debris and dust. These debris and dust can be washed by the nozzle 52 and fall into the cleaning pool 1. In order to ensure the cleanliness of the circulating water (excluding iron filings), a filter plate 54 is fixedly arranged between the bottom of the mounting frame 2 and the inner wall of the cleaning pool 1, that is, the filter plate 54 divides the cleaning pool 1 into two areas, and water can pass through the filter plate 54, but the metal wire debris cannot. The lower end of the circulating water tank is connected to the area of ​​the cleaning pool 1 without metal debris. Therefore, it can be avoided that metal debris will enter the circulating water tank.

[0048] In order to further cool and clean the wire, the wire needs to enter the cleaning pool 1. First, a support frame 6 is fixedly connected to one side of the mounting frame 2, and three mounting shafts 7 are fixedly connected to the support frame 6. At the end of each mounting shaft 7, a guide wheel 8 is rotatably connected through a bearing.

[0049] It should be noted that a guide wheel 8 is also installed on one side of the mounting frame 2 and located on the wire path. It has the same function and structure as the guide wheel 8 at the end of the mounting shaft 7 and plays a supporting and guiding role for the wire.

[0050] After passing through the wire drawing plate 4, the metal wire will pass through four guide wheels 8 in sequence, that is, first enter the cleaning pool 1, and then exit the cleaning pool 1. Therefore, there is cleaning water in the cleaning pool 1, and the above-mentioned entry into the cleaning pool 1 refers to entering below the liquid level of the cleaning pool 1.

[0051] The metal wire enters below the liquid level, which can further play the effect of cooling, and simultaneously in order to thoroughly remove the debris attached to the metal wire surface. The supporting frame 6 is also fixedly connected with a side connecting rod 9, and the end of the side connecting rod 9 is provided with a cleaning sponge 10.

[0052] The cleaning sponge 10 has a loose and porous structure and can absorb water when it is placed below the liquid level. The metal wire passes through the cleaning sponge 10, and the iron filings on the sponge are blocked and absorbed by the sponge and separated from the metal wire.

[0053] Because the metal wire needs to be rewound and reeled up after drawing, it is necessary to remove the moisture attached to the surface of the metal wire. Therefore, two corresponding air-drying cylinders 12 are arranged on the path of the metal wire, and the air-drying cylinders 12 are hollow cylindrical structures.

[0054] The support frame 6 is also fixedly connected with an air inlet pipe 11, which is connected to two air drying cylinders 12. When air is introduced into the air inlet pipe 11, moisture on the surface of the metal wire can be dried. If hot air is introduced, the drying efficiency is higher. And there is no need to touch the metal wire, so as to avoid deformation of the metal wire.

[0055] As the wire drawing process accumulates, metal scraps will accumulate in the cleaning pool 1 (the area where the cleaning sponge 10 is located). In order to remove and recycle the metal scraps, a collecting tank 17 is provided on the side of the cleaning pool 1 away from the mounting frame 2, and the height of the collecting tank 17 is lower than the bottom surface of the cleaning pool 1. A scraper 13 for cleaning the metal scraps is also provided, so the metal scraps are heavy and generally settle at the bottom of the cleaning pool 1.

[0056] In order to drive the scraper 13 to move, a push plate 14 is fixedly connected to the scraper 13, and one end of the push plate 14 extends out of the cleaning pool 1. In addition, a threaded rod 15 and a guide rod 16 are arranged on one side of the cleaning pool 1. One end of the threaded rod 15 is also connected to a motor, and the threaded rod 15 and the guide rod 16 both penetrate the push plate 14. A mounting seat (not numbered in the figure) is arranged outside the threaded rod 15 and the guide rod 16. The threaded rod 15 and the mounting seat are rotatably connected. (This is the prior art)

[0057] When the motor controls the threaded rod 15 to rotate, in cooperation with the guide rod 16, the push plate 14 can be driven to move along the direction of the guide rod 16. Therefore, in the process where the push plate 14 drives the scraper 13 to move from the filter plate 54 to the collecting tank 17, the metal chips deposited on the bottom of the pool can be pushed into the collecting tank 17.

[0058] In actual use, a collection box (not marked in the figure) can be placed in the collection tank 17, so the metal chips in the pool can be taken out by directly taking out the collection box. The taken out metal chips can also be recycled.

[0059] The implementation process and principle of a wire drawing device in the embodiment of the present application are as follows:

[0060] (I) When installing the wire drawing plate 4, just press the wire drawing plate 4 at the corresponding positioning groove 31. One end of the metal wire passes through the hole on the wire drawing plate 4, and then passes through four guide wheels 8 in sequence. Cooperate with the winding mechanism (not shown in the figure) to drive the metal wire to move. The subsequent metal wire is stretched and thinned when passing through the wire drawing plate 4.

[0061] (ii) The circulating water pipe 53 also needs to cooperate with the water pump and the nozzle 52, so that the cooling water is sprayed from the nozzle 52 and sprayed on the metal wire to cool the metal wire and wash away the metal chips on the metal wire. Then the metal wire enters the coolant to further cool down, and cooperates with the cleaning sponge 10 to completely remove the chips attached to the metal wire.

[0062] (iii) (hot) air is input through the air inlet pipe 11 to air dry the metal wire passing through the air drying cylinder 12 to remove surface moisture for subsequent winding.

[0063] (IV): By controlling the scraper 13 to move back and forth, the metal chips in the cleaning pool 1 are pushed into the collecting tank 17, so as to facilitate the recycling of the chips and prevent excessive metal chips from affecting the subsequent cooling work.

[0064] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
