Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically, it relates to a wire drawing device that allows for easy replacement of the wire drawing die. Background Technology

[0002] In the field of metal processing, wire drawing equipment is the core equipment for producing metal wire. Its core working principle is: applying tension to the metal wire through the die hole of the wire drawing die, causing the wire to pass through the die hole and be stretched to a preset diameter. At the same time, the tension mechanism controls the stress state of the wire during the stretching process to avoid problems such as wire breakage due to excessive tension or loosening and uneven thickness due to insufficient tension. The final result is a metal wire with a smooth surface and precise dimensions. Wire drawing equipment is widely used in industries such as electronics, building materials, and machinery manufacturing.

[0003] An existing wire drawing device was found to have the following issues during use:

[0004] 1. The wire drawing templates of existing wire drawing equipment are mostly fixed to the mounting base with bolts. The disassembly process is cumbersome and cannot be quickly disassembled and replaced, resulting in poor practicality.

[0005] 2. When producing wires of different materials, the existing adjustment method requires a lot of time to adapt the tension parameters, which not only increases the workload of operators, but may also lead to unqualified batches of wires due to untimely adjustment, increasing production loss costs, thus resulting in poor practicality. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides a solution to the technical problems mentioned in the background art, such as the inability to quickly assemble and disassemble the wire drawing template and the slow adjustment of the tension mechanism.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing device that facilitates the replacement of wire drawing dies, comprising an operating table, an installation groove provided on the top of the operating table, an installation plate provided at the bottom of the installation groove, a sliding component provided at the rear end of the top of the installation plate, and installation blocks slidably provided on both sides of the rear end of the top of the installation plate via the sliding component. Each set of installation blocks has a groove at one end opposite to the other, and a wire drawing template is fitted into the grooves of both sets of installation blocks. A tension mechanism is provided at the front end of the top of the installation plate.

[0010] The present invention is further configured such that the tension mechanism includes a rotating roller and a tension roller, and fixed plates are provided on both sides of the top front end of the mounting plate. The two ends of the rotating roller are respectively rotatably connected to the top end of one set of fixed plates. Adjustment components are provided on the bottom front end of the opposite side of the two sets of fixed plates, and the bottom front end of the opposite side of the two sets of fixed plates are rotatably connected to one end of the tension roller through the adjustment components. The rotating roller guides the wire to enter the tension adjustment area stably, avoiding direct friction between the wire and the fixed plate and causing surface scratches. The tension roller changes the winding angle of the wire by moving up and down, which can accurately adapt to the tension requirements of wires of different materials and diameters. The integrated design of the adjustment components and the fixed plates makes the tension adjustment structure compact, eliminating the need for an additional independent adjustment bracket and saving equipment space. At the same time, the rotatable connection between the tension roller and the adjustment components reduces jamming during adjustment and ensures smooth tension changes.

[0011] The present invention is further configured such that the adjustment component includes a drive motor, and each of the two sets of fixed plates has a groove at the bottom of its front end on opposite sides. A connecting screw is rotatably installed in the groove of one set of fixed plates, and a connecting block is threadedly connected to the outside of the connecting screw. The connecting block is slidably connected to the groove of the corresponding set of fixed plates. A drive motor is installed at the top of the fixed plates, and the bottom output end of the drive motor passes through the fixed plate and connects to the top of the connecting screw. Another set of connecting blocks is slidably installed in the groove of the other set of fixed plates. A sliding plate is installed at one end of each of the two sets of connecting blocks, and both ends of the tension roller are rotatably connected to one end of the sliding plate of one set of fixed plates. By driving the motor, the movement distance of the tension roller can be precisely controlled by controlling the rotation direction and time, avoiding the error of manual judgment during adjustment, and realizing precise quantitative adjustment of tension. The synchronous linkage design of the two sets of connecting blocks and sliding plates ensures that both ends of the tension roller always remain horizontally raised and lowered, avoiding the tension roller tilting due to unilateral adjustment, which would cause uneven force on the wire and thickness deviation, further improving the stability of wire quality.

[0012] The present invention is further configured such that the sliding component includes a bidirectional screw, and a sliding groove is provided at the top rear end of the mounting plate. The bidirectional screw is rotatably disposed within the sliding groove of the mounting plate. Both ends of the outer side of the bidirectional screw are threadedly connected to sliding blocks. The two sets of sliding blocks are slidably connected to one end of the sliding groove of the mounting plate, and the tops of the two sets of sliding blocks are respectively connected to the bottom of one set of mounting blocks. The bidirectional thread design of the bidirectional screw enables synchronous and symmetrical adjustment of the two sets of sliding blocks and the mounting blocks. The two sets of mounting blocks can be opened and closed synchronously simply by rotating the bidirectional screw, without the need to adjust one side separately, which greatly simplifies the operation steps and improves the template installation efficiency. The threaded connection of the bidirectional screw has self-locking property. After the mounting blocks are clamped to the template, even if the equipment vibrates during operation, the sliding blocks will not move on their own, ensuring long-term stable fixation of the template and avoiding template displacement caused by loosening of traditional bolts.

[0013] The present invention is further configured such that guide grooves are uniformly provided on the outer surfaces of the rotating roller and the tension roller; the guide grooves provide a clear movement path for the wire, preventing the wire from sliding to both sides of the roller body during the stretching process, colliding and rubbing with the fixed plate or other parts of the equipment, reducing scratches on the wire surface, and improving the appearance quality of the product.

[0014] The present invention is further configured such that anti-slip pads are provided on the inner walls of the grooves of both sets of mounting blocks, and both ends of the wire drawing template are tightly attached to one end of a set of anti-slip pads; the friction enhances the stability of the template fixation, avoids the template from loosening or shifting in the groove due to equipment vibration, ensures accurate alignment of the die hole and the wire, reduces wire stretching deviation, and the elastic anti-slip pads can buffer the collision between the template and the groove, avoid wear caused by hard contact between the metal template and the mounting block, extend the service life of the wire drawing template and the mounting block, and reduce the cost of consumable replacement.

[0015] The present invention is further configured such that the left end of the bidirectional screw passes through the left end of the corresponding mounting plate slide groove and the mounting groove and is provided with a rotating handle; the rotating handle increases the rotation arm and the force application area, so that the operator can easily rotate the bidirectional screw without the need for tools such as wrenches, which greatly reduces the intensity of operation and is especially suitable for scenarios where templates are frequently changed.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a wire drawing device that facilitates the replacement of wire drawing dies, and has the following beneficial effects:

[0018] 1. No tools are needed to disassemble bolts or loosen clamps; the opening and closing of the mounting block can be quickly controlled by the sliding component alone, significantly shortening the time for changing the wire drawing template and avoiding production interruptions caused by frequent downtime. It adapts to the production needs of quick switching between multiple wire specifications. The fitting design of the mounting plate and the operating table mounting groove provides stable support for the sliding component, mounting block, and tension mechanism, preventing component displacement due to vibration during equipment operation. It ensures the accurate relative position of the wire drawing template and the tension mechanism, reducing deviations during wire stretching. The structure of two sets of mounting blocks jointly clamping the wire drawing template ensures balanced force on the template, making it less prone to loosening on one side. At the same time, the limiting effect of the mounting block groove can accurately position the wire drawing template, avoiding repeated manual alignment adjustments, improving template installation accuracy, and reducing the risk of die hole wear and wire breakage.

[0019] 2. The rotating roller guides the wire steadily into the tension adjustment area, avoiding direct friction between the wire and the fixed plate that could cause surface scratches. The tension roller changes the winding angle of the wire by moving up and down, which can accurately adapt to the tension requirements of wires of different materials and diameters. The integrated design of the adjustment component and the fixed plate makes the tension adjustment structure compact, eliminating the need for an additional independent adjustment bracket and saving equipment space. At the same time, the rotating connection between the tension roller and the adjustment component reduces jamming during adjustment and ensures smooth tension changes. Attached Figure Description

Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] Please see Figure 1-5 A wire drawing device that facilitates the replacement of wire drawing dies includes an operating table 1. The top of the operating table 1 is provided with a mounting groove 2, and the bottom of the mounting groove 2 is provided with a mounting plate 3. The top rear end of the mounting plate 3 is provided with a sliding component. Mounting blocks 4 are slidably provided on both sides of the top rear end of the mounting plate 3 through the sliding component. The two sets of mounting blocks 4 are provided with grooves at opposite ends, and a wire drawing template 5 is locked in the grooves of the two sets of mounting blocks 4. A tension mechanism is provided at the top front end of the mounting plate 3.

[0030] In this embodiment, when the wire drawing template 5 needs to be installed, the sliding component at the top rear end of the mounting plate 3 is operated to make the two sets of mounting blocks 4 slide towards each other along the sliding component. The two ends of the wire drawing template 5 are respectively inserted into the grooves of the two sets of mounting blocks 4. Then, the distance between the two sets of mounting blocks 4 is adjusted by the sliding component to make the grooves tightly clamp the wire drawing template 5, thus completing the fixing of the wire drawing template 5. After the equipment is started, the metal wire first passes through the tension mechanism at the top front end of the mounting plate 3. The tension mechanism adjusts the wire tension and then passes through the die hole of the wire drawing template 5 for stretching. When the wire drawing template 5 needs to be replaced, the sliding component is operated in the opposite direction to make the two sets of mounting blocks 4 slide away from each other, releasing the clamping constraint on the wire drawing template 5. The old wire drawing template 5 can be directly removed, and after replacing it with a new wire drawing template 5, the above clamping steps are repeated to resume production.

[0031] More specifically, when the mounting block 4 slides, the bidirectional screw 13 in the groove of the mounting plate 3 is rotated. The sliding blocks 14 at both ends of the bidirectional screw 13 slide along the groove of the mounting plate 3 under the action of the threaded transmission. The tops of the two sets of sliding blocks 14 are respectively connected to the bottom of a set of mounting blocks 4. The mounting block 4 moves synchronously with the sliding blocks 14. When the sliding blocks 14 are close to each other, the mounting block 4 drives the groove to clamp the wire drawing template 5. When the sliding blocks 14 are far apart, the groove of the mounting block 4 is disengaged from the wire drawing template 5, making it easy to remove or replace the template.

[0032] Please see Figure 1 and Figure 4As one implementation of the tension mechanism: The tension mechanism includes a rotating roller 6 and a tension roller 7. Fixed plates 8 are provided on both sides of the top front end of the mounting plate 3. The two ends of the rotating roller 6 are rotatably connected to the top of one end of a set of fixed plates 8 respectively. Adjustment components are provided at the bottom front end of the opposite side of the two sets of fixed plates 8. The bottom front end of the opposite side of the two sets of fixed plates 8 is rotatably connected to one end of the tension roller 7 through the adjustment components.

[0033] Specifically, after the equipment is started, the metal wire is drawn out from the external wire feeding mechanism, first passing around the outside of the rotating roller 6, then passing down around the outside of the tension roller 7, and finally passing through the die hole of the drawing template 5. During the stretching process, if it is necessary to adjust the wire tension, operate the adjustment components on the two sets of fixed plates 8. The adjustment components drive the tension roller 7 to move up and down along the fixed plate 8. When the tension roller 7 moves down, the winding angle of the wire decreases and the tension increases; when the tension roller 7 moves up, the winding angle of the wire increases and the tension decreases, until the tension is adjusted to a state suitable for the current wire.

[0034] Please refer to Figures 2-4 As a further embodiment of the tension mechanism: the adjustment component includes a drive motor 9, and two sets of fixed plates 8 are provided with sliding grooves at the bottom of their opposite front ends. A connecting screw 10 is rotatably disposed in the sliding groove of one set of fixed plates 8, and a connecting block 11 is threadedly connected to the outside of the connecting screw 10. The connecting block 11 is slidably connected to the corresponding set of fixed plates 8 sliding grooves. A drive motor 9 is disposed at the top of the set of fixed plates 8, and the bottom output end of the drive motor 9 passes through the fixed plate 8 and is connected to the top of the connecting screw 10. Another set of connecting blocks 11 is slidably disposed in the sliding groove of the other set of fixed plates 8. A sliding plate 12 is disposed at one opposite end of each of the two sets of connecting blocks 11, and both ends of the tension roller 7 are rotatably connected to one end of a set of sliding plates 12.

[0035] Specifically, when adjusting the tension, the drive motor 9 on the top of one set of fixed plates 8 is started. The output end of the drive motor 9 passes through the fixed plate 8 and connects to the top of the connecting screw 10 in the slide groove, driving the connecting screw 10 to rotate in the slide groove of the fixed plate 8. The connecting block 11, which is threaded to the outside of the connecting screw 10, slides up and down along the slide groove of the fixed plate 8 under the action of thread transmission. The connecting block 11 in the slide groove of the other set of fixed plates 8 slides synchronously. The slide plate 12 at the opposite end of the two sets of connecting blocks 11 moves synchronously with the connecting blocks 11. The slide plate 12 drives the tension roller 7, which is rotated at both ends, to move up and down. When the tension roller 7 moves to the preset position (the wire tension reaches the required level), the drive motor 9 is turned off, the connecting screw 10 stops rotating, the connecting block 11 and the slide plate 12 remain fixed, and the tension roller 7 maintains the current position, thus completing the tension adjustment.

[0036] In summary, the overall equipment is in use (or running):

[0037] Place the mounting plate 3 into the mounting slot 2 at the top of the operating table 1, hold the rotating handle 17 at the left end of the bidirectional screw 13 and rotate it. The bidirectional screw 13 drives the two sets of sliding blocks 14 in the sliding groove of the mounting plate 3 to move closer to each other. The mounting blocks 4 at the top of the sliding blocks 14 move synchronously until the anti-slip pads 16 on the inner wall of the groove of the two sets of mounting blocks 4 are tightly attached to both ends of the wire drawing template 5, thus completing the installation of the wire drawing template 5.

[0038] Start the drive motor 9 on the top of the fixed plate 8. Its output end drives the connecting screw 10 in the slide groove of the fixed plate 8 to rotate. The connecting block 11 slides along the slide groove. The connecting block 11 in the slide groove of another set of fixed plates 8 moves synchronously. The sliding plate 12 of the two sets of connecting blocks 11 drives the tension roller 7 to rise and fall, and adjust to the appropriate tension. The metal wire first winds along the guide groove 15 on the outside of the rotating roller 6, then winds around the guide groove 15 on the outside of the tension roller 7, and finally passes through the die hole of the wire drawing template 5.

[0039] When the equipment is started, the wire is stretched by the drawing template 5 after the tension roller 7 is adjusted. When the drawing template 5 needs to be replaced, the rotating handle 17 is rotated in the opposite direction. The sliding block 14 drives the mounting block 4 to move away from each other. The old drawing template 5 is removed, and after the new template is replaced, the rotating handle 17 is rotated again to lock it. The tension roller 7 is adjusted again to resume processing.

For all the fixed connections mentioned above, welding is preferred.
