[0004] In the above-mentioned utility model, the wire is drawn by a drawing die during the drawing process. However, after long-term use, the die hole of the drawing die is severely worn or the geometric shape deviates, which will cause the wire to be subjected to uneven tension when passing through, resulting in uneven wire drawing and thus affecting the drawing quality. Therefore, it is necessary to provide a wire drawing machine that can quickly replace the drawing die to improve the uniformity of wire drawing. Utility Model Content

[0005] The purpose of this utility model is to provide a wire and cable drawing machine to solve the problem mentioned in the background art. In the above-mentioned utility model, the wire is drawn by a drawing die during the drawing process. However, after long-term use, the die hole of the drawing die is severely worn or the geometric shape deviates, which will cause the wire to be subjected to uneven tension when passing through, resulting in uneven wire drawing and thus affecting the drawing quality.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a wire and cable drawing machine, comprising:

[0008] The base plate, the bracket, and the wire drawing frame are provided, wherein the bracket is fixed to one end of the base plate and the wire drawing frame is fixed to one side of the upper surface of the base plate.

[0009] A drawing assembly includes a groove, a first drawing die, a second drawing die, a slider, and mounting holes. The groove is located at the center of the top surface of the support, and one end of the groove passes through the support. The first drawing die is fixed on both sides of the top surface of the support and is located on both sides of the groove. The second drawing die is located at the center of the top surface of the support. The slider is fixed on the lower surface of the second drawing die and is slidably installed inside the groove. Four mounting holes are located on both sides of the second drawing die.

[0010] Furthermore, five rotating rollers are rotatably installed inside the drawing frame, and corresponding guide rollers pass through the center of the five rotating rollers. The five rotating rollers are staggered. A slide rail is fixed on the upper surface of the base plate, and a guide block is slidably installed on the upper surface of the slide rail. A take-up roller is fixed on one side of the base plate, and a wire core passes through the inside of the first drawing die, and the wire core passes through the guide roller.

[0011] Furthermore, a telescopic spring is fixed inside the mounting hole, and a retaining post is fixed to one end of the telescopic spring. A fixing hole is opened on one side of the two first wire drawing dies, and the end of the retaining post extends into the fixing hole.

[0012] Furthermore, four movable grooves are provided on both sides of the outer surface of the second wire drawing die, and the movable grooves are interconnected with the mounting holes. A baffle is fixed on one side of the telescopic spring, and the baffle passes through the movable groove.

[0013] Furthermore, it also includes an anti-winding component, which includes a first pressure spring, a second pressure spring, and connecting plates. The first pressure spring is set in pairs, with a total of two sets, which are respectively fixed on both sides of the inner bottom surface of the wire drawing frame. There are two second pressure springs, which are respectively fixed in the middle of the two sets of first pressure springs. The two connecting plates are fixed on the upper ends of the corresponding first pressure spring and second pressure spring.

[0014] Furthermore, the top surface of the connecting plate is provided with an installation groove, and a rotating column is rotatably installed inside the installation groove, with the outer surface of the rotating column in contact with the outer surface of the guide roller.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through the setting of a base plate, bracket, wire drawing frame, rotating roller, wire guide roller, and drawing assembly, allows the operator to quickly replace damaged wire drawing dies when the die hole is worn. The operator simply holds the baffle with both hands, causing the baffle to simultaneously compress the telescopic spring inside the mounting hole. The telescopic spring also moves the locking pin towards the center, allowing it to exit the fixed hole. At this point, the second wire drawing die can be moved within the groove to remove the worn second wire drawing die. The above steps are repeated to move a new second wire drawing die to the center of the first wire drawing die. Releasing the baffle allows the telescopic spring to quickly return to its original shape under the spring force, causing the end of the locking pin to extend into the fixed hole. This ensures the uniformity of wire core drawing, effectively solving the problem of worn wire drawing dies, significantly improving production efficiency, ensuring product quality, reducing maintenance costs, and enhancing equipment stability.

[0017] II. Based on the first beneficial effect, by setting up a wire drawing frame, rotating roller, wire guide roller and anti-winding component, after the wire core passes through the first wire drawing die and the second wire drawing die, one end of the wire core passes through five guide rollers. Under the action of the spring force, the first pressure spring and the second pressure spring drive the connecting plate to push upward, so that the rotation of the rotating column contacts the guide roller. The rotating column will abut against the guide roller, so that the wire core is stably fixed inside the guide roller, which facilitates the subsequent winding work of the guide block. The stable fixing of the wire core ensures a continuous production process and avoids tangling when the wire core is wound. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1 to 4 As shown, this embodiment is a wire and cable drawing machine, comprising:

[0033] The base plate 11, bracket 12, and wire drawing frame 121 are provided. The bracket 12 is fixed to one end of the base plate 11, and the wire drawing frame 121 is fixed to one side of the upper surface of the base plate 11. Five rotating rollers 13 are rotatably installed inside the wire drawing frame 121. A corresponding guide roller 14 passes through the center of each of the five rotating rollers 13, and the five rotating rollers 13 are staggered. A slide rail 15 is fixed to the upper surface of the base plate 11, and a guide block 151 is slidably installed on the upper surface of the slide rail 15. A take-up roller 16 is fixed to one side of the base plate 11, and a wire core 17 passes through the inside of the first wire drawing die 22, and the wire core 17 passes through the guide roller 14.

[0034] The base plate 11 ensures that the entire wire drawing machine remains stable during operation, reducing vibration and displacement. Five rotating rollers 13 are rotatably installed inside the wire drawing frame 121. These rotating rollers 13 are used to guide the movement direction of the wire core 17. Corresponding guide rollers 14 pass through the center of the rotating rollers 13. The staggered distribution design helps to distribute the tension on the wire core 17 more evenly.

[0035] The drawing assembly includes a groove 21, a first drawing die 22, a second drawing die 23, a slider 24, and mounting holes 25. The groove 21 is located at the center of the top surface of the bracket 12, and one end of the groove 21 passes through the bracket 12. The first drawing die 22 is fixed on both sides of the top surface of the bracket 12 and is located on both sides of the groove 21. The second drawing die 23 is located at the center of the top surface of the bracket 12. The slider 24 is fixed on the lower surface of the second drawing die 23 and is slidably installed inside the groove 21. Four mounting holes 25 are opened on both sides of the second drawing die 23.

[0036] The first wire drawing die 22 has a wire core 17 running through it, and performs preliminary drawing of the wire core 17. The second wire drawing die 23 is located between the two first wire drawing dies 22, and further refines the size and surface quality of the wire core 17.

[0037] A telescopic spring 27 is fixed inside the mounting hole 25, and a locking post 28 is fixed to one end of the telescopic spring 27. A fixing hole 221 is opened on one side of the two first wire drawing dies 22, and the end of the locking post 28 extends into the fixing hole 221. Four movable grooves 26 are opened on both sides of the outer surface of the second wire drawing die 23, and the movable grooves 26 are interconnected with the mounting hole 25. A baffle 29 is fixed on one side of the telescopic spring 27, and the baffle 29 passes through the movable groove 26.

[0038] The slider 24 is fixed to the lower surface of the second wire drawing die 23, so that the die can slide smoothly in the slide groove 21. The mounting hole 25 is fixed with a telescopic spring 27 to provide elastic support for the locking post 28. One end of the telescopic spring 27 is fixed with the locking post 28. When the baffle 29 is released, the spring returns to its original shape and pushes the locking post 28 into the fixing hole 221.

[0039] Working principle:

[0040] When the die hole of the wire drawing die is worn, the worker only needs to hold the baffle 29 with both hands. The baffle 29 simultaneously drives the telescopic spring 27 to compress inside the mounting hole 25, and the telescopic spring 27 drives the locking post 28 to move towards the middle, so that the locking post 28 is removed from the fixing hole 221. At this time, the second wire drawing die 23 can be pushed to move in the slide 21. The worn second wire drawing die 23 can be removed. Then, the above steps are repeated to move the new second wire drawing die 23 to the middle of the first wire drawing die 22. Release the hand holding the baffle 29. Under the action of the spring force, the telescopic spring 27 will quickly restore its deformation. The telescopic spring 27 drives the end of the locking post 28 to extend into the fixing hole 221, quickly replace the damaged wire drawing die, and ensure the uniformity of wire core 17 drawing.

[0041] This step not only effectively solves the problem caused by wear on the wire drawing die, but also significantly improves production efficiency, ensures product quality, reduces maintenance costs, and enhances equipment stability.

[0042] Please see Figures 1 to 4 As shown; this embodiment, based on the above embodiment, further includes:

[0043] The anti-winding assembly includes a first pressure spring 31, a second pressure spring 32, and a connecting plate 33. The first pressure spring 31 is set in pairs, and there are two sets, which are fixed on both sides of the inner bottom surface of the wire drawing frame 121. There are two second pressure springs 32, which are fixed in the middle of the two sets of first pressure springs 31. The two connecting plates 33 are fixed on the upper ends of the corresponding first pressure spring 31 and second pressure spring 32. The top surface of the connecting plate 33 is provided with a mounting groove 34. A rotating column 35 is rotatably installed inside the mounting groove 34, and the outer surface of the rotating column 35 is in contact with the outer surface of the guide roller 14.

[0044] The main function of the first pressure spring 31 is to provide an upward elastic force to ensure that the connecting plate 33 can stably push the rotating column 35 upward. The outer surface of the rotating column 35 contacts the outer surface of the guide roller 14, and the axis of the rotating column 35 is set parallel to the axis of the guide roller 14, which ensures good contact between the two, reduces friction and wear, and can fix the wire core 17 inside the guide roller 14 to prevent the wire core 17 from becoming loose or tangled.

[0045] Working principle:

[0046] After the wire core 17 passes through the first drawing die 22 and the second drawing die 23, one end of the wire core 17 is passed through five guide rollers 14. Under the action of the spring force, the first pressure spring 31 and the second pressure spring 32 drive the connecting plate 33 to push upward, so that the rotation of the rotating column 35 contacts the guide roller 14. The rotating column 35 will abut against the guide roller 14, so that the wire core 17 is stably fixed inside the guide roller 14, which facilitates the subsequent winding work of the guide block 151.

[0047] This step, which secures the core 17, ensures a continuous production process and prevents the core 17 from tangling during winding.
