Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel wire drawing transmission equipment, and in particular to a transmission structure for steel wire drawing. Background Technology
[0002] This wire drawing transmission equipment mainly consists of the following mechanical components: two sets of rectangular cast iron bases are fixed parallel to each other on the worktable, and a steel transmission roller is mounted on the upper end of each base via ball bearings. The two sets of transmission rollers are arranged horizontally and symmetrically, and the roller spacing is adjustable to accommodate the conveying needs of steel wires of different diameters. The power system uses two asynchronous motors, which are directly connected to the drive shafts of the transmission rollers via rigid couplings. When the motors are powered on, their output torque directly drives the transmission rollers to produce synchronous rotational motion through the couplings.
[0003] The main mechanical defect of the existing structure is that, because the two drive systems operate completely independently, when the motors rotate asynchronously due to differences in winding impedance or fluctuations in power supply voltage, a deviation in the circumferential linear speed of the two sets of transmission rollers will occur. This speed difference will cause sliding friction between the conveyed steel wires on the roller surfaces, leading not only to wear of the coating on the steel wire surface but also potentially to twisting and deforming the steel wire due to uneven tension. In more severe cases, the accumulated speed difference can cause the steel wires to accumulate and entangle on the transmission rollers, requiring a shutdown for manual straightening, which seriously affects continuous production efficiency. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art and to propose a transmission structure for steel wire drawing that can transport and organize express delivery.
[0005] To achieve the above objectives, this utility model proposes a transmission structure for steel wire drawing, comprising: a base and a conveying roller rotatably connected to the base.
[0006] It also includes: a support base, a displacement base, a swing rod, and a push roller;
[0007] The support base is slidably connected to the base;
[0008] The displacement seat consists of two pieces, both of which are slidably connected to the support seat in a synchronous manner.
[0009] The swing rods are respectively swing-connected to the displacement seats, and the support seats are provided with synchronous driving components, which are respectively connected to the swing rods;
[0010] The push roller is rotatably connected to the swing arm, and the push rollers can be arranged in a relative manner.
[0011] The synchronous drive component includes: a rotating rod fixedly connected to a support base and a connecting rod slidably connected within the rotating rod. A first bevel gear set is respectively provided on the connecting rod. One end of the first bevel gear set is fixedly connected to the swing rod. A first motor is fixedly connected to the support base. A second bevel gear set is provided on the support base. One end of the second bevel gear set is fixedly connected to the connecting rod, and the other end is fixedly connected to the output shaft of the first motor.
[0012] Preferably, a limiting block is fixedly connected to the connecting rod, and a sliding groove is provided on the rotating rod for the limiting block to slide.
[0013] Preferably, a cuboid rod is fixedly connected inside the rotating rod, and the cuboid rod is slidably connected to the connecting rod.
[0014] Preferably, both the cuboid rod and the connecting rod are rotatably connected with ball bearings, the ball bearings on the cuboid rod are in contact with the connecting rod, and the ball bearings on the connecting rod are in contact with the inner wall of the rotating rod.
[0015] Preferably, a support rod is fixedly connected to the base, and the support rod is slidably connected to the support seat.
[0016] Preferably, a threaded rod is rotatably connected to the base, the threaded rod is threadedly connected to the support seat, and a motor is fixedly connected to the base, the output shaft of the motor being fixedly connected to the threaded rod.
[0017] Preferably, the push roller is provided with staggered friction grooves.
[0018] The beneficial effects of this utility model compared with the prior art are as follows:
[0019] 1. When the motor drives the support base to move forward as a whole, the symmetrically clamped push rollers generate an absolutely synchronous linear pushing force, forcing the steel wire to move forward at a constant speed between the conveyor rollers, completely eliminating the possibility of relative sliding friction between the steel wire and the conveyor roller surface caused by the difference in speed of the two drive sources.
[0020] 2. The motor drives the threaded rod to rotate, causing the entire support base to precisely translate along the base. The bidirectional screw mechanism inside the support base ensures that the two displacement seats on both sides can always move synchronously towards or away from each other, laying the foundation for symmetrical movement. The key synchronous drive component transmits power through the meshing of a bevel gear set, converting the rotation of the rotating rod into the rotation of the connecting rod. Then, through another set of bevel gears, the rotational motion is precisely converted into the synchronous angular displacement of the two swing rods on both sides. Ultimately, the two push rollers installed at the ends of the swing rods swing towards the center line of the steel wire at exactly the same angle and reliably clamp the steel wire. The specially designed cross-textured surface of the push rollers significantly increases the contact resistance with the steel wire.
[0021] 3. The ingenious sliding fit design between the cuboid rod and the connecting rod ensures lossless transmission of rotational torque while allowing the connecting rod to freely extend and retract within the rotating rod, adapting to changes in the distance between the displacement seats. The ball bearing structure effectively reduces frictional resistance during relative movement between the rotating rod and the connecting rod. The support rod provides additional stable guidance and support for long-distance movement of the support seat.
[0022] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0031] like Figs. 1 to 3 A transmission structure for drawing steel wire includes: a base 1 and a conveying roller 2 rotatably connected to the base 1, wherein the conveying roller 2 is used to guide the steel wire;
[0032] The transmission structure in this utility model also includes: a support base 3, a displacement base 4, a swing rod 6, and a push roller 7;
[0033] The support base 3 is slidably connected to the base 1. The support base 3 is driven by a threaded rod 18 and a motor 19. The threaded rod 18 is rotatably connected to the base 1 and threadedly connected to the support base 3. The motor 19 is fixedly connected to the base 1, and its output shaft is fixedly connected to the threaded rod 18. Therefore, when the motor 19 starts, it drives the threaded rod 18 to rotate, thus enabling the threaded rod 18 to move the support base 3. Two displacement seats 4 are provided, both slidably and synchronously connected to the support base 3. The support base 3 is driven by a double... The system is driven by a lead screw and a motor. The bidirectional lead screw is rotatably connected to the support base 3, while the second motor 19 is fixedly connected to the support base 3. The output shaft of the second motor 19 is fixedly connected to the bidirectional lead screw, thus the second motor 19 can drive the bidirectional lead screw to rotate, causing the lead screw to move the displacement blocks threaded to it, resulting in synchronous relative movement of the displacement blocks. The swing rods 6 are oscillatingly connected to the displacement seats 4. The support base 3 is equipped with synchronous drive components, which are connected to the swing rods 6. The push rollers 7 are rotatably connected to the swing rods 6, and these push rollers 7 can be arranged in a relative position.
[0034] The synchronous drive components include: a rotating rod 8 fixedly connected to the support base 3 and a connecting rod 9 slidably connected within the rotating rod 8. A limit block 10 is fixedly connected to the connecting rod 9. A sliding groove 11 for the limit block 10 to slide is provided on the rotating rod 8. A bevel gear set 12 is respectively provided on the connecting rod 9. One end of the bevel gear set 12 is fixedly connected to the swing rod 6. A motor 13 is fixedly connected to the support base 3. A bevel gear set 2 14 is provided on the support base 3. One end of the bevel gear set 2 14 is fixedly connected to the connecting rod 9, and the other end is fixedly connected to the output shaft of the motor 13. The bevel gear set 12 includes two bevel gears rotatably connected to the displacement seat 4. One bevel gear is fixedly connected to the connecting rod 9, and the other is fixedly connected to the swing rod 6. One bevel gear set 14 consists of two meshing bevel gears, both of which are rotatably connected to the support base 3. One bevel gear is fixedly connected to the output shaft of the motor 13, and the other bevel gear is fixedly connected to the rotating rod 8. Therefore, the motor 13 drives one bevel gear to rotate, which in turn drives the other bevel gear to rotate. This causes the bevel gear to drive the rotating rod 8 to drive the connecting rod 9 to rotate, which in turn drives one bevel gear to rotate. This causes the other bevel gear to drive the swing rod 6 to rotate, which in turn drives the push roller 7 to swing until it is in contact with the steel wire. The movement of the support base 3 then causes the push roller 7 to push the steel wire forward, thus achieving the conveying of the steel wire.
[0035] Specifically, a cuboid rod 15 is fixedly connected inside the rotating rod 8. The cuboid rod 15 is slidably connected to the connecting rod 9. The cuboid rod 15 is used to limit the connecting rod 9, so that the connecting rod 9 can rotate together with the rotating rod 8 during rotation. The slidable connection between the cuboid rod 15 and the connecting rod 9 does not affect the rotation of the connecting rod 9, nor does it affect the extension and retraction of the connecting rod 9 within the rotating rod 8.
[0036] Specifically, ball bearings 16 are rotatably connected to both the cuboid rod 15 and the connecting rod 9. The ball bearings 16 on the cuboid rod 15 are in contact with the connecting rod 9, and the ball bearings 16 on the connecting rod 9 are in contact with the inner wall of the rotating rod 8. By rotatably connecting the ball bearings 16 to the cuboid rod 15 and the connecting rod 9, the friction between the connecting rod 9 and the rotating rod 8 is reduced.
[0037] Specifically, a support rod 17 is fixedly connected to the base 1, and the support rod 17 is slidably connected to the support seat 3. The support rod 17 is used to support the support seat 3.
[0038] Specifically, the push roller 7 is provided with staggered friction grooves 20, which are used to increase the friction between the steel wire and the push roller 7.
[0039] The principle of this invention: This transmission structure achieves precise wire feeding through a three-stage mechanical linkage. The base 1 serves as the overall support platform, and the conveying roller 2 is responsible for initial guidance and positioning. The core transmission process begins with motor 2 19 driving the threaded rod 18 to rotate, causing the support seat 3 to move linearly along the base 1. Inside the support seat 3, a bidirectional lead screw, driven by motor 3, causes the two sets of displacement seats 4 to produce symmetrical displacement.
[0040] Motor 13 drives bevel gear set 2 14 to rotate rotating rod 8. Connecting rod 9, embedded in rotating rod 8, transmits torque through cuboid rod 15. Bevel gear set 12 at the end of connecting rod 9 converts the rotational motion into angular displacement of swing rod 6, ultimately causing push roller 7 to clamp the steel wire. Specially designed friction groove 20 enhances the friction of the contact surface through interlaced texture, while the ball bearing structure 16 effectively reduces frictional loss between rotating rod 8 and connecting rod 9.
[0041] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
