Description

Technical Field

[0001] This invention relates to the field of layer winding machine technology, and more specifically, to a constant tension welding wire layer winding machine. Background Technology

[0002] If the tension is not constant during the layering process of welding wire, it will lead to uneven stress distribution inside the welding wire, which will affect its straightness. A welding wire layering machine with constant tension can eliminate the stress of the welding wire by precisely controlling the tension, so that its straightness is controlled within the specified index, which meets the requirements of smooth wire feeding when the automatic welding machine is welding, and avoids wire clamping.

[0003] Among the existing publicly available documents, patent publication number CN223422124U discloses a welding wire layer winding machine. This technology allows the mounting rod to squeeze the welding wire spool, thereby automatically removing the layered welding wire spool without manual removal, making it more convenient and faster. However, this technology still has the following drawbacks.

[0004] During the winding process, the welding wire layer winding machine needs to use a constant winding force to achieve the winding process. However, it is difficult to achieve large-area extrusion layer winding during the winding process, resulting in poor positioning stability of the layer winding. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a constant tension welding wire winding machine, including a rotating disk, a support column fixed on the upper surface of the rotating disk, a protruding strip column fixed at the top of the support column, and a winding disk slidably connected to the outer wall of the support column; The outer wall of the convex post is provided with a distributed extrusion winding assembly, which is used to distribute and extrude the winding disc. The distributed extrusion winding assembly includes: A pressure plate is slidably connected to the outer wall of the protruding column. Pressure strips are fixed on both sides of the pressure plate, and an arc-shaped plate is fixedly connected to the bottom end of each pressure strip. The arc-shaped plate is used to press against the upper surface of the winding disc. Two pressure rods are fixed to the lower surface of the pressure plate, and a pressure plate is fixedly connected to the bottom end of each pressure rod.

[0006] In a preferred embodiment, the two pressure strips are symmetrically arranged about the pressure plate, and the vertical cross-sectional shape of the pressure strips is L-shaped.

[0007] In a preferred embodiment, the two arc-shaped plates are symmetrically arranged about the support column, and the cross-sectional shape of the arc-shaped plates is circular arc.

[0008] In a preferred embodiment, the two pressure plates are symmetrically arranged about the support column, and the pressure rod and the sleeve pressure plate are arranged perpendicularly.

[0009] In a preferred embodiment, a motor is mounted at the bottom of the rotating disk, and the output end of the motor is fixedly connected to the rotating disk; The motor is used to drive the rotating disk to rotate, and a socket plate is fixedly installed on the outer wall of the motor.

[0010] In a preferred embodiment, a sleeve block is fixed on the upper surface of the sleeve plate at a position on one side of the protruding post, and a bolt is threaded onto the inner wall of the sleeve block for pressing the protruding post.

[0011] In a preferred embodiment, a gripping rod is fixed on the upper surface of the pressure plate and at a position on one side of the sleeve block, wherein the cross-sectional area of ​​the top end of the gripping rod is larger than the cross-sectional area of ​​its bottom end.

[0012] In a preferred embodiment, a support ring is fixed to the upper surface of the pressure strip, and a connecting column is fixed to the inner wall of the support ring. A counterweight is installed at the top of the connecting column, and the counterweight is used to counterweight the connecting column.

[0013] This invention, through an innovatively designed distributed extrusion winding assembly, achieves multi-point, uniform, and controllable extrusion winding of the welding wire reel, thereby maintaining constant tension during the welding wire layer winding process and significantly improving winding quality and equipment stability. Specific beneficial effects are as follows: Achieve large-area uniform extrusion and improve winding positioning stability This invention employs a distributed extrusion winding assembly. A pressure plate simultaneously drives the pressure strips on both sides, the arc-shaped plate, the pressure rod, and the pressure plate, forming multiple symmetrically distributed extrusion points to achieve comprehensive and uniform pressure on the upper surface of the winding disc. This design avoids the stress concentration problem caused by traditional single-point or localized extrusion, ensuring uniform stress on the welding wire during winding, tighter interlayer adhesion, and significantly improving the positioning stability and overall structural strength of the winding.

[0014] Enhanced compression adjustability and ease of operation By incorporating a sleeve block and bolt structure on the pressure plate, rapid locking and releasing of the convex column can be achieved, facilitating adjustment of the pressure plate's downward position and pressure. Combined with a grip rod design, operators can easily control the raising and lowering of the pressure plate, enabling quick loading and unloading and fine-tuning of pressure, thus improving the equipment's applicability and operational efficiency.

[0015] The counterweight structure enhances the extrusion strength and adapts to different winding requirements. A support ring, connecting column, and counterweight are added to the upper part of the pressure strip. By adjusting the weight of the counterweight, vertical auxiliary pressure can be applied to the pressure strip. This structure not only enhances the continuous pressing force of the curved plate on the winding disc, but also allows for flexible adjustment of the counterweight according to different welding wire materials, winding layers, and tension requirements, achieving more precise tension control and winding effect.

[0016] Symmetrical structure and balanced stress extend equipment lifespan. Key components such as the pressure bar, curved plate, and pressure plate are all arranged symmetrically to ensure balanced force during winding and reduce equipment vibration and wear caused by uneven loading. At the same time, the arc-shaped design of the curved plate fits well with the upper surface of the winding reel, avoiding scratches or indentations on the surface of the welding wire and ensuring the integrity of the welding wire's appearance and performance.

[0017] The motor drive and structure are integrated to achieve efficient and stable winding. The motor is fixed to the bottom of the rotating disk via a socket plate, driving the rotating disk to rotate the winding disk at a constant speed. Combined with the constant pressure provided by the distributed extrusion component, the welding wire is continuously and smoothly wound under constant tension, effectively avoiding problems such as tension fluctuation, layer loosening, and wire jamming that are common in traditional winding.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1 - Figure 4 The diagram shows a constant tension welding wire layer winding machine, which is equipped with a distributed extrusion winding assembly. The distributed extrusion winding assembly enables large-area extrusion layer winding, enhances the layer winding positioning stability, and ensures that the welding wire layer is wound under constant tension, resulting in higher positioning stability of the welding wire layer winding. The specific structural configuration of the distributed extrusion winding assembly is as follows.

[0025] Example 1: In this embodiment, as Figure 1 - Figure 3 As shown, a support column 2 is fixed to the upper surface of the rotating disk 1, and a protruding column 3 is fixed to the top of the support column 2. A winding disk 9 is slidably connected to the outer wall of the support column 2. A distribution extrusion and winding assembly is provided on the outer wall of the protruding column 3. The distribution extrusion and winding assembly is used to distribute and extrude the winding disk 9. The distribution extrusion and winding assembly includes: a sleeve pressure plate 4, which is slidably connected to the outer wall of the protruding column 3. Pressure strips 5 are fixed on both sides of the sleeve pressure plate 4. An arc plate 6 is fixedly connected to the bottom end of each pressure strip 5. The arc plate 6 is used to extrude on the upper surface of the winding disk 9; two pressure rods 7, which are fixed to the lower surface of the sleeve pressure plate 4. A pressure plate 8 is fixedly connected to the bottom end of each pressure rod 7. The two pressure strips 5 are symmetrically arranged about the sleeve pressure plate 4, and the vertical cross-sectional shape of the pressure strips 5 is L-shaped. The two arc plates 6 are symmetrically arranged about the support column 2, and the cross-sectional shape of the arc plates 6 is arc-shaped. The two pressure plates 8 are symmetrically arranged about the support column 2, and the pressure rods 7 are perpendicular to the sleeve pressure plate 4.

[0026] In this embodiment, as Figure 2 As shown, a motor 10 is mounted on the bottom of the rotating disk 1, and the output end of the motor 10 is fixedly connected to the rotating disk 1; the motor 10 is used to drive the rotating disk 1 to rotate, and a socket plate 11 is fixedly mounted on the outer wall of the motor 10. The socket plate 11 supports the motor 10, thereby realizing the driving operation of the motor 10.

[0027] In this embodiment, as Figure 3 As shown, a sleeve block 12 is fixed on the upper surface of the pressure plate 4, located on one side of the protruding post 3. A bolt 13 is threadedly connected to the inner wall of the sleeve block 12. The bolt 13 is used to press the protruding post 3. By rotating the bolt 13, the bolt 13 and the sleeve block 12 are threadedly engaged, so that the bolt 13 is pressed on the right side of the protruding post 3, increasing the pressing force.

[0028] In this embodiment, as Figure 3 As shown, a gripping rod 14 is fixed on the upper surface of the pressure plate 4 and located on one side of the sleeve block 12. The cross-sectional area of ​​the top end of the gripping rod 14 is larger than that of the bottom end. By holding the outer wall of the gripping rod 14 with the hand, the gripping rod 14 drives the pressure plate 4 to move down, which facilitates the pressing operation of the pressure plate 4.

[0029] During implementation, motor 10 can be either a servo motor or a stepper motor, and its speed can be steplessly adjusted via an external controller to adapt to the winding requirements of welding wires of different diameters and materials. The socket plate 11 has multiple mounting holes for easy bolt fixing to the worktable or frame, enhancing the overall stability of the equipment. The curvature of the arc plate 6 can be customized according to the contour of the upper surface of the winding disc 9 to ensure complete contact and avoid excessive local stress.

[0030] In actual operation, the operator can first lift the pressure plate 4 to an appropriate height by holding the lever 14, place the winding disc 9, and then slowly press it down so that the arc plate 6 and the pressure plate 8 simultaneously contact the upper surface of the winding disc. Then tighten the bolt 13 to fix the pressure plate 4 to the convex column 3, completing the pre-tightening. After starting the motor 10, the winding disc 9 is subjected to continuous and uniform radial pressure during rotation, thereby realizing the layer-by-layer winding of the welding wire under constant tension.

[0031] In this embodiment, the constant tension welding wire winding machine is used by inserting pre-embedded bolts into the holes of the sleeve plate 11, which supports the motor 10. The hand is held on the outer wall of the gripping rod 14, which drives the sleeve pressure plate 4 to move downward. As the sleeve pressure plate 4 moves downward, it slides down along the outer wall of the convex column 3. At the same time, the sleeve pressure plate 4 drives the pressure strip 5 to move downward, and the pressure strip 5 drives the arc plate 6 to move downward. The arc plate 6 presses against the upper surface of the winding disc 9. Simultaneously, the sleeve pressure plate 4 drives the pressure rod 7 to move downward, and the pressure rod 7 drives the pressure plate 8 to move downward. The pressure plate 8 presses against the upper surface of the winding disc 9. The winding disc 9 is compressed at multiple points. By rotating the bolt 13, the bolt 13 and the sleeve block 12 are connected by threaded engagement. The bolt 13 is pressed against the right side of the convex column 3, and the convex column 3 is compressed and locked to prevent the sleeve pressure plate 4 from moving and to improve the stability of the downward compression of the sleeve pressure plate 4. By starting the motor 10, the motor 10 drives the rotating disk 1 to rotate the winding disc 9. The winding disc 9 is firmly pressed against the rotating disk 1, so that the winding disc 9 drives the welding wire layer to achieve constant tensile tension for winding, realizing multi-point distributed compression and winding of the welding wire.

[0032] Example 2: In this embodiment, as Figure 4 As shown, a support ring 15 is fixed on the upper surface of the pressure strip 5, and a connecting post 16 is fixed on the inner wall of the support ring 15. A counterweight 17 is installed at the top of the connecting post 16, and the counterweight 17 is used to counterweight the connecting post 16.

[0033] The counterweight 17 can be made of metal, and its weight can be replaced or stacked according to the actual winding tension requirements. The connecting post 16 and the support ring 15 can be connected by threads or fixed with pins, which facilitates the installation and removal of the counterweight. In practical applications, the addition of the counterweight not only enhances the downward pressure of the pressure bar 5, but also, to a certain extent, counteracts the inertial vibration during motor start-up and shutdown, further improving the stability of the winding process.

[0034] In addition, a buffer pad or spring structure can be installed between the support ring 15 and the connecting post 16 to absorb minor impacts that may occur during the winding process and protect the surface of the welding wire from damage. This counterweight structure is particularly suitable for winding high-strength, large-diameter welding wires and can effectively prevent interlayer loosening and deformation.

[0035] In this embodiment, the constant tension welding wire winding machine uses a counterweight block 17 to counterweight the connecting column 16, and the connecting column 16 to counterweight the pressure bar 5. At the same time, the pressure bar 5 supports the support ring 15, and the support ring 15 provides positioning operation for the connecting column 16. This achieves a counterweight operation of vertically moving the pressure bar 5 downward, improving the firmness of the arc plate 6 pressing against the winding disc 9.
