Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, specifically a single-layer wrapping wire pressing square wire device. Background Technology

[0002] In the field of electrical wire manufacturing, square and flat wires are widely used in new energy vehicle drive motors, aerospace equipment and high-frequency transformers due to their excellent conductivity and space utilization. The quality of the insulation layer coating on the surface of square and flat wires directly affects their temperature resistance, insulation reliability and service life. At present, the industry generally adopts the biaxial forming process for insulation layer coating in the square pressing process. This process uses two sets of orthogonally arranged pressure rollers to continuously extrude the square and flat wires, so that the insulation material adheres to the surface of the wire.

[0003] The biaxial forming process relies on mechanical extrusion to achieve insulation layer coating, but the complex cross-sectional shape of the square flat wire makes it easy for uneven adhesion between the film layer and the wire surface to occur during the pressing process. Therefore, we need to propose a single-layer wrapping wire pressing device for square wire. Utility Model Content

[0004] The purpose of this invention is to provide a single-layer wrapping wire pressing device. By setting a four-axis forming flat wire assembly, the four-axis forming structure achieves multi-directional uniform pressure on the wire through orthogonally arranged pressure rollers, thereby solving the problems mentioned in the background art.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution:

[0025] A single-layer wrapping wire pressing device includes: a positioning base plate 1, a housing 2 fixedly mounted on the top of the positioning base plate 1, a cross-shaped through groove 3 on one side wall of the housing 2 for guiding the entry and exit of the cable, and a flat wire assembly 4 for four-axis forming to press the cable into square shape inside the housing 2. By integrating the four-axis forming flat wire assembly 4 with the modular guide design, the accuracy and efficiency of the Teflon film wrapping process for flat wires are significantly improved. The four-axis forming structure achieves multi-directional uniform pressure on the wire through orthogonally arranged pressure rollers, effectively solving the problem of uneven film adhesion caused by the complex cross-sectional shape in the traditional biaxial process, ensuring that the Teflon film can be tightly attached in the corners and flat areas, avoiding the generation of bubbles or wrinkles, thereby greatly improving the pressure resistance and long-term reliability of the insulation layer.

[0026] The flat wire assembly 4 includes a power module 5 for moving the cable, two sets of power modules 5 arranged orthogonally, an adjustment module 6 for adjusting the clamping force, and a driven roller 7. The power module 5 and the adjustment module 6 arranged inside the housing 2 work together to adapt to the processing requirements of different specifications of flat wires by adjusting the clamping force and the wire conveying speed, thereby enhancing the process flexibility. The orthogonal layout of the four-axis forming flat wire assembly 4 can cover the pressing requirements of the wire in the entire circumference and adapt to the processing of complex cross-sectional shapes.

[0027] A column 8 is fixedly installed on the top of the positioning base plate 1. The inside of the column 8 is hollow, and the inner cavity of the column 8 is provided with a guide component 9 for guiding the cable after the pressing process.

[0028] The power module 5 includes a drive motor 501, a reduction gearbox 502, and an active roller 503. The reduction gearbox 502 is fixedly installed on the top of the positioning base plate 1. The active roller 503 is connected to the output end of the reduction gearbox 502 via a rotating shaft. The drive motor 501 is fixedly installed on the top of the reduction gearbox 502, and the input end of the reduction gearbox 502 is connected to the output end of the drive motor 501. The drive motor 501 reduces its speed and increases its torque through the reduction gearbox 502, ensuring that the active roller 503 pulls the cable at a constant linear speed. The drive motor 501 is a servo motor, which, together with the gear transmission system of the reduction gearbox 502, can precisely control the cable conveying speed. The surface of the active roller 503 is covered with an anti-slip rubber layer to increase the friction with the cable and prevent slippage.

[0029] The adjustment module 6 includes a screw 601, a rotating wheel 602, a threaded sleeve 603, a rotating seat 604, and a rotating roller 605. The threaded sleeve 603 is fixedly embedded in the side wall of the housing 2. The screw 601 is threadedly connected to the inside of the threaded sleeve 603. The rotating wheel 602 is fixedly connected to one end of the screw 601. The other end of the screw 601 is rotatably connected to one side of the rotating seat 604. The rotating roller 605 is rotatably connected to the inner cavity of the rotating seat 604. The clamping force of the rotating roller 605 on the cable is adjusted by manually rotating it.

[0030] It also includes a sliding seat 606 and a slider 607 for limiting the rotation seat 604 and the rotating roller 605. The sliding seat 606 is fixedly installed in the inner cavity of the housing 2. The slider 607 is slidably connected to the sliding seat 606 and fixedly connected to the rotation seat 604. The sliding seat 606 and the slider 607 further limit the movement trajectory of the rotation seat 604 to ensure the stability of the pressing process. The screw 601 adopts a trapezoidal thread design to improve adjustment accuracy and durability. The rotating roller 605 is hard chrome plated to reduce the coefficient of friction and enhance wear resistance. The fit clearance between the sliding seat 606 and the slider 607 is controlled within 0.1mm to avoid vibration or displacement during the pressing process.

[0031] The guide assembly 9 includes a lead screw 901, which adopts a ball screw structure, has high transmission efficiency and small backlash. The top and bottom ends of the lead screw 901 are rotatably mounted on the inner top and inner bottom of the column 8, respectively. The top end of the lead screw 901 passes through the column 8 and is fixedly connected to a handwheel 902. A movable block 903 is threadedly connected to the outer wall of the lead screw 901. A fixed block 904 is fixedly connected to one side of the movable block 903. A guiding module 905 is provided on one side of the fixed block 904. Rotating the handwheel 902 can drive the movable block 903 to move up and down along the lead screw 901, thereby driving the fixed block 904 and the guiding module 905 to adjust the height.

[0032] The guiding module 905 includes a mounting base 9051, which is fixedly mounted on one side wall of the fixing block 904. A guide roller 9052 and a pressure rod 9053 are rotatably mounted on one side of the mounting base 9051. The pressed cable passes between the guide roller 9052 and the pressure rod 9053, forming a cable channel between the guide roller 9052 and the pressure rod 9053. The elastic pressure of the pressure rod 9053 ensures that the cable is tightly attached to the surface of the guide roller. The surface of the guide roller 9052 is provided with a V-shaped groove that matches the cross-sectional shape of the cable to prevent the cable from sliding laterally. The pressure rod 9053 has a built-in spring mechanism that can automatically compensate for the cable dimensional tolerances and ensure guiding stability.

[0033] A limiting groove 10 adapted to the fixing block 904 is provided on one side wall of the column 8. The fixing block 904 is slidably connected to the inside of the limiting groove 10. The limiting groove 10 restricts the movement range of the fixing block 904 and prevents the guide component 9 from overtravel. The limiting groove 10 is embedded with a polytetrafluoroethylene bushing to reduce the frictional resistance when the fixing block 904 slides, and at the same time prevents metal contact from generating wear particles that contaminate the cable surface.

[0034] The cable enters the flat wire assembly 4 through the cross-shaped through-slot 3 of the housing 2. The drive motor 501 drives the active roller 503 to rotate through the reduction gearbox 502, pulling the cable to move at a constant speed. Two sets of orthogonally arranged adjustment modules 6 adjust the position of the screw 601 by manually rotating the rotating wheel 602, so that the rotating roller 605 applies multi-directional pressure to the cable, gradually pressing the round wire into a square flat wire. At the same time, the Teflon film is synchronously coated on the surface of the wire after preheating.

[0035] The screw 601 of the adjustment module 6 cooperates with the sliding seat 606 to adjust the clamping force of the rotating roller 605 on the cable in real time, ensuring that the Teflon film is evenly adhered to the corners and flat areas. The limiting design of the sliding seat 606 and the slider 607 further stabilizes the movement trajectory of the rotating roller 605, avoiding film damage or wire deformation due to uneven pressure.

[0036] After being pressed, the cable enters the guide assembly 9 inside the column 8. The height of the guide roller 9052 is adjusted by rotating the handwheel 902, ensuring the cable is stably output along a preset path. The pressure rod 9053 of the guiding module 905 works in conjunction with the guide roller 9052 to apply slight pressure to the cable to eliminate residual stress, ensuring that the coated Teflon film adheres tightly and has a smooth surface. The power module 5 provides stable conveying power, the adjustment module 6 achieves precise pressing control, and the guide assembly 9 completes the final shaping. All modules are integrated with the housing 2 via the positioning base plate 1, forming a compact continuous processing system that meets the needs of high-precision and high-efficiency industrial production. Through four-axis pressing and modular guiding design, this mechanism solves the problems of uneven film bonding and low efficiency in traditional biaxial processes, significantly improving the insulation performance and production consistency of Teflon film-coated flat wires.
