Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cable processing, and more specifically, to a wire drawing machine for cable processing. Background Technology

[0002] In the cable processing flow, the wire drawing machine is a key piece of equipment that draws thick-diameter metal wires (such as copper wire and iron wire) into thin-diameter wires that meet the specifications of cable conductors. Its drawing accuracy and subsequent winding effect directly determine the conductivity and processing adaptability of the cable conductor. As cables develop towards thinner diameters and multiple specifications, the shortcomings of traditional wire drawing machines for cable processing have become increasingly prominent: existing wire drawing machines generally suffer from the drawbacks of being inconvenient to quickly adjust according to the drawing diameter and being unable to directly achieve uniform winding, which seriously restricts processing flexibility and production efficiency, and can also easily affect conductor quality.

[0003] Traditional wire drawing machines typically have fixed drawing dies and traction mechanisms. When processing conductor wires of different diameters, multiple components (such as drawing dies and traction wheels) need to be disassembled and replaced. This adjustment process is cumbersome and time-consuming, making it difficult to quickly respond to multi-specification production needs. If the adjustment is not done properly, it can also lead to uneven wire stretching, resulting in diameter deviations or surface scratches, affecting the conductor's conductivity and structural stability, and increasing the difficulty of subsequent processing steps.

[0004] Therefore, the development of a wire drawing machine for cable processing that can flexibly adjust the wire diameter and directly and uniformly rewind the wire has become an urgent need to improve the efficiency and quality of cable conductor processing. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a wire drawing machine for cable processing, which solves the technical problems that existing wire drawing machines generally have, such as inconvenience in quickly adjusting according to the wire diameter and inability to directly achieve uniform winding.

[0006] According to one aspect, at least one embodiment of this disclosure provides a wire drawing machine for cable processing, comprising: A bracket and a circular opening, wherein the circular opening is formed on the surface of the bracket; A winding assembly, wherein the winding assembly is disposed on the support; A wire drawing assembly, wherein the wire drawing assembly is disposed on the surface of the bracket; The wire drawing assembly includes several sets of stretching rollers, with three stretching rollers in each set. Each set has a driven gear at one end of the middle stretching roller. The other side of the bracket is horizontally rotatably connected to a drive shaft. The drive shaft is driven to rotate by electricity. The drive shaft is equipped with several drive gears, which mesh with the corresponding driven gears.

[0007] As a further technical solution, the surface of the bracket is provided with several pairs of fixing rods, and each pair of fixing rods is fitted with a wire-drawing sleeve, the two ends of which are fixedly connected to the fixing rod by bolts.

[0008] According to another aspect, in at least one embodiment of the present invention, the winding assembly includes a guide frame, the guide frame being horizontally fixed within the bracket, the guide frame being located on one side of the circular opening, and a movable frame being connected within the guide frame via a horizontal linear drive.

[0009] As a further technical solution, a drive motor is provided on the outer surface of the moving frame, a shaft frame is provided at the output end of the drive motor, a take-up reel is fitted on the shaft frame, and a number of slots are provided on the side end face of the take-up reel.

[0011] As a further technical solution, a guide tube is fixedly connected to the surface of the bracket, and the guide tube is located on one side of one of the wire drawing sleeves.

[0012] As a further technical solution, several of the driving gears and the driven gears are all bevel gears.

[0013] As a further technical solution, anti-deviation grooves are provided on the surface of the stretching rollers, and the inside of the anti-deviation grooves is a smooth arc-shaped structure surface.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the wire drawing assembly solves the problems of cumbersome adjustments and poor adaptability of traditional wire drawing machines through synchronous drive and convenient sleeve replacement design. Multiple sets of tension rollers are triangularly distributed, working in conjunction with bevel gear transmission to ensure synchronous operation, providing uniform tension to the wire and avoiding uneven stretching. The wire drawing sleeve is fixed to the fixed rod with bolts, eliminating the need to disassemble the entire structure for replacement and quickly adapting to different wire diameter requirements. Anti-deviation grooves and guide tubes work together to guide the wire, reducing surface scratches and ensuring drawing accuracy. This structure eliminates the need for frequent equipment adjustments, significantly shortening changeover time and improving the processing efficiency of multi-specification cables. Simultaneously, synchronous drive and precise shaping ensure stable wire quality, providing high-quality conductor raw materials for subsequent cable processing. Attached Figure Description

[0017] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3 As shown, it illustrates a wire drawing machine for cable processing according to an embodiment of the present disclosure, comprising: A bracket 1 and a circular opening 2, wherein the circular opening 2 is formed on the surface of the bracket 1; A winding assembly 4 is disposed on the bracket 1; Wire drawing assembly 3 is disposed on the surface of the bracket 1; The wire drawing assembly 3 includes several sets of stretching rollers 3-1, with three stretching rollers 3-1 in each set. One end of the middle stretching roller 3-1 in each set is provided with a driven gear 3-2. The other side surface of the bracket 1 is horizontally rotatably connected to a drive shaft 3-3. The drive shaft 3-3 is driven to rotate by electricity. Several drive gears 3-4 are provided on the drive shaft 3-3. The drive gears 3-4 mesh with the corresponding driven gears 3-2. Several pairs of fixing rods 3-5 are provided on the surface of the bracket 1. A wire drawing sleeve 3-6 is fitted on each pair of fixing rods 3-5. The two ends of the wire drawing sleeve 3-6 are fixedly connected to the fixing rods 3-5 by bolts.

[0024] In some examples, in order to achieve stable and efficient wire drawing during cable processing, and to meet the needs of quick replacement of wire drawing for different inner diameters, and to avoid uneven wire stretching caused by asynchronous drive in traditional wire drawing equipment, a wire drawing assembly 3 was designed. This assembly includes several sets of stretching rollers 3-1, with each set of 3 stretching rollers 3-1 arranged in a triangular pattern. This arrangement can form a stable clamp on the wire from different directions, ensuring that the wire is subjected to balanced force during stretching and preventing wire deviation or breakage.

[0025] The driven gear 3-2 at one end of each set of intermediate stretching rollers 3-1 meshes with the corresponding drive gear 3-4 on the drive shaft 3-3 on the other side of the support 1. When the drive shaft 3-3 is driven to rotate by electricity, the drive gear 3-4, in conjunction with the driven gear 3-2, can synchronously drive each set of intermediate stretching rollers 3-1 to rotate. Then, the friction between the intermediate rollers and the two side rollers drives the entire set of stretching rollers 3-1 to operate, ensuring that the speed of all stretching rollers 3-1 is coordinated, providing a stable and uniform stretching force for the wire, and achieving efficient wire drawing.

[0026] Several pairs of fixing rods 3-5 on the surface of bracket 1 provide installation support for the wire drawing sleeve 3-6. After the wire drawing sleeve 3-6 is fitted onto the fixing rods 3-5, it is fixedly connected by bolts. This ensures that the wire drawing sleeve 3-6 is stable in position during the wire drawing process, avoiding displacement due to vibration that affects the wire drawing accuracy. It also allows for quick removal of the old wire drawing sleeve 3-6 and replacement with a new one by removing the bolts. When it is necessary to process wires of different diameters, only the wire drawing sleeve 3-6 with the corresponding inner diameter needs to be replaced. There is no need to adjust the overall equipment structure, which greatly shortens the changeover time and improves the adaptability of the equipment to the processing of cables of different specifications.

[0027] The inner diameter accuracy and surface smoothness of the wire drawing sleeve 3-6 are strictly controlled. When the wire passes through the wire drawing sleeve 3-6, it can be precisely drawn to the target diameter under the pulling force of the stretching roller 3-1. At the same time, the inner wall of the wire drawing sleeve 3-6 can shape and polish the wire surface, reduce scratches on the wire surface, and improve product quality.

[0028] During operation, drive shaft 3-3 drives drive gear 3-4 to rotate, which in turn drives stretching roller 3-1 to rotate via driven gear 3-2. The wire is guided by drawing sleeve 3-6 and stretched under the clamping of stretching roller 3-1. When changing specifications, the drawing sleeve 3-6 can be replaced by removing the bolts. Gear linkage ensures stable wire drawing, and the detachable design improves sleeve changing efficiency. The coordinated operation of all components achieves stable and efficient wire drawing and quick sleeve changing, meeting the needs of cable processing.

[0029] like Figures 1-3As shown, this embodiment proposes that the winding assembly 4 includes a guide frame 4-1, which is horizontally fixed inside the bracket 1. The guide frame 4-1 is located on one side of the circular opening 2. A movable frame 4-2 is horizontally linearly driven inside the guide frame 4-1. A drive motor 4-3 is provided on the outer surface of the movable frame 4-2. A shaft frame 4-4 is provided at the output end of the drive motor 4-3. A winding reel 4-5 is fitted onto the shaft frame 4-4. Several slots 4-6 are opened on the side end face of the winding reel 4-5. Several insertion holes 4-7 are opened at one end of the shaft frame 4-4. A clamping frame 4-8 is inserted into the slots 4-6. Several insertion rods 4-9 are provided on the side surface of the clamping frame 4-8. The insertion rods 4-9 are inserted into the insertion holes 4-7. The clamping frame 4-8 and one end of the shaft frame 4-4 are fixedly connected by bolts.

[0030] In some examples, in order to achieve uniform winding of the wire after drawing and to avoid the wire being concentrated in a certain area of ​​the winding reel 4-5 during winding, resulting in accumulation or looseness, or the winding reel 4-5 being unstable and affecting the winding quality, a winding assembly 4 is designed. This assembly includes a horizontally fixed guide frame 4-1 inside the bracket 1, which provides a horizontal moving track for the moving frame 4-2. The moving frame 4-2 inside the guide frame 4-1 is connected by a horizontal linear drive and can move back and forth along the guide frame 4-1. Its moving speed can be precisely matched with the wire drawing speed and the rotation speed of the winding reel 4-5, ensuring that the wire can be evenly distributed on the winding reel 4-5, forming a layered and orderly winding, and avoiding local accumulation or excessive gaps. The drive motor 4-3 on the outer surface of the moving frame 4-2 has a shaft frame 4-4 at the output end that mounts the take-up reel 4-5. When the drive motor 4-3 is running, it can drive the shaft frame 4-4 and the take-up reel 4-5 to rotate synchronously, providing power for wire winding. Several slots 4-6 on the side end face of the take-up reel 4-5 cooperate with the insertion hole 4-7 and the clamping frame 4-8 at one end of the shaft frame 4-4. After the clamping frame 4-8 is inserted into the slot 4-6, the insertion rod 4-9 on its side surface is inserted into the insertion hole 4-7. Then, the clamping frame 4-8 is fixedly connected to one end of the shaft frame 4-4 by bolts, forming a multi-directional fixing structure. This structure can firmly fix the take-up reel 4-5 on the shaft frame 4-4, preventing the take-up reel 4-5 from axial movement or relative sliding due to vibration or wire tension during the rotation and winding process, and ensuring the stable rotation of the take-up reel 4-5. In addition, the guide frame 4-1 is located on one side of the circular opening 2 on the surface of the bracket 1, which can guide the wire after drawing to smoothly enter the winding assembly 4 through the circular opening 2, avoiding the wire from being damaged by friction with the edge of the bracket 1 during transmission; the reciprocating stroke of the moving frame 4-2 can be adjusted according to the width of the winding reel 4-5, adapting to the winding requirements of different sizes of winding reels 4-5, and improving the versatility of the assembly.

[0031] During operation, the drive motor 4-3 drives the winding reel 4-5 to rotate and wind the wire. The horizontal linear drive drives the moving frame 4-2 to move back and forth, ensuring that the wire is wound evenly. The winding reel 4-5 is fixed to the bolts via the clamping frame 4-8 and the insertion rod 4-9. The linear drive achieves uniform winding, the multi-directional fixation ensures stable winding, and the coordinated movement of all components completes repeated uniform winding, ensuring winding quality and efficiency.

[0032] For example, such as Figure 1 As shown, a guide tube 5 is fixedly connected to the surface of the bracket 1, and the guide tube 5 is located on one side of one of the wire drawing sleeves 3-6.

[0033] In some examples, the guide tube 5, which is fixedly connected to the surface of the bracket 1, is located on one side of one of the wire drawing sleeves 3-6. This pre-guides the wire before drawing, ensuring that the wire enters the wire drawing sleeve 3-6 in a straight line. This prevents the wire from being scratched or worn due to friction between the wire and the entrance of the wire drawing sleeve 3-6 caused by deviation in the transmission path. The inner diameter of the guide tube 5 is matched with the initial diameter of the wire, which not only provides precise guidance but also reduces the frictional resistance between the wire and the inner wall of the tube.

[0034] For example, such as Figure 2 As shown, several of the driving gears 3-4 and the driven gears 3-2 are all bevel gears.

[0035] In some examples, the spatially staggered shaft transmission characteristics of the bevel gears can be adapted to the vertical layout of the drive shaft 3-3 (horizontally mounted) and the intermediate stretching roller 3-1 shaft (longitudinally mounted). Power transmission can be achieved efficiently without additional adjustment of the shaft installation direction, simplifying the structural design of the wire drawing assembly 3. The bevel gear tooth surface has a larger contact area, which can evenly distribute the force in the transmission process, reduce the load on a single tooth, reduce the wear rate of the gear, and extend its service life.

[0036] For example, such as Figure 1 As shown, anti-deviation grooves 6 are provided on the surface of the stretching roller 3-1, and the inside of the anti-deviation grooves 6 is a smooth arc-shaped structure surface.

[0037] In some examples, the surface of the stretching roller 3-1 is provided with anti-deviation grooves 6. The interior of the anti-deviation groove 6 is a smooth, arc-shaped surface. The arc-shaped groove surface can closely fit the surface of the wire, limiting the wire laterally and preventing it from shifting to either side of the stretching roller 3-1 during the stretching process. This ensures that the wire always moves along the central trajectory of the stretching roller 3-1, avoiding uneven stretching or breakage due to deviation. The smooth groove surface reduces the frictional resistance between the wire and the stretching roller 3-1, preventing scratches on the wire surface due to friction and protecting the appearance quality of the wire.

[0038] In practical use: Select the appropriate wire drawing sleeve 3-6 with the corresponding inner diameter according to the required wire diameter for cable processing, and fit it onto the fixing rod 3-5 of the bracket 1. Secure both ends of the wire drawing sleeve 3-6 with bolts. Pass one end of the metal wire through the guide tube 5, and then sequentially through the anti-deviation grooves 6 of each set of wire drawing sleeves 3-6 and the stretching rollers 3-1. Start the electric drive of the wire drawing assembly 3, causing the drive shaft 3-3 to drive the drive gear 3-4 to rotate. The drive gear 3-4 meshes with the driven gear 3-2, thereby driving each set of stretching rollers 3-1 to rotate synchronously. The stretching rollers 3-1 clamp the wire and apply tension, shaping and thinning the wire through the wire drawing sleeves 3-6. At the same time, start the winding assembly 4. The drive motor 4-3 drives the shaft frame 4-4 and the winding reel 4-5 to rotate. The horizontal linear drive drives the moving frame 4-2 to move back and forth along the guide frame 4-1, guiding the thinned wire to be evenly wound on the winding reel 4-5. The take-up reel 4-5 is fixed to the shaft frame 4-4 by the clamping frame 4-8, the insert rod 4-9 and bolts to ensure stable winding. If the wire diameter needs to be changed, simply remove the bolts and replace the wire drawing sleeve 3-6; after winding is completed, loosen the bolts and remove the clamping frame 4-8 and the take-up reel 4-5 to achieve flexible wire drawing and uniform winding throughout the process.
