Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, specifically to a heating and straightening mechanism for wire drawing equipment with adjustable angle. Background Technology

[0002] In the field of metal wire processing, wire drawing equipment is widely used in the diameter reduction process of steel wire, copper wire, and other metal wires. After wire drawing, the wire often experiences varying degrees of bending, twisting, or residual stress due to repeated drawing and traction, which affects the straightness of the wire and the quality of subsequent processing. Therefore, existing wire drawing equipment typically has a straightening mechanism at the wire exit end, which uses multiple sets of straightening rollers to bend the wire in the opposite direction, gradually restoring the wire to a relatively straight state.

[0003] In existing technologies, wire drawing equipment adjusts the angle of the straightening wheel assembly via a support base, causing the straightening wheel to form a certain angle relative to the wire's running direction. This alters the bending path of the wire as it passes through the straightening wheel, thereby improving the straightening effect. However, in actual use, different specifications of wire vary in diameter, hardness, and degree of curvature. Simply adjusting the angle of the straightening wheel is often insufficient to adequately adapt to various processing conditions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable-angle heating and straightening mechanism for wire drawing equipment, which solves the problem that simply adjusting the angle of the straightening wheel is often insufficient to fully adapt to various processing conditions for wires of different specifications.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable-angle heating and straightening mechanism for a wire drawing device, comprising a base, a guide frame mounted on the outer wall of the base, a guide frame one mounted on the upper surface of the base, a heating sleeve mounted on the upper surface of the base via a support block, a support seat hinged to the inside of the base via a rotating shaft, guide frames two mounted on both sides of the support seat, a hydraulic rod mounted on the upper surface of the base via a short block, a fixed frame rotatably connected to the output end of the hydraulic rod via a rotating shaft, the inside of the fixed frame mounted on the outer wall of the support seat, an I-shaped frame slidably connected to the inside of the support seat, a U-shaped plate slidably connected to the outer wall of the I-shaped frame, a straightening wheel rotatably connected to the inner side of the U-shaped plate, and an adjustment mechanism provided inside the support seat.

[0006] The above scheme achieves the following: the guide frame initially limits and guides the drawn wire, ensuring its precise entry into subsequent processing positions and preventing deviation. Guide frame one further constrains the wire's trajectory, ensuring it enters the heating sleeve smoothly and centrally. The heating sleeve softens the wire, eliminating residual stress from the drawing process and providing the necessary thermal conditions for subsequent straightening. Guide frames two on both sides of the support base facilitate the constraint of the input and output wires. Multiple straightening wheels arranged in a staggered pattern apply straightening force to the softened wire.

[0007] Preferably, the adjustment mechanism includes a motor, the outer wall of which is installed inside the support base, a bidirectional lead screw is fixedly provided at the output end of the motor, a transmission block is threadedly connected to the outer wall of the bidirectional lead screw, the upper surface of the transmission block is installed on the lower surface of the I-shaped frame, and trapezoidal frames are installed on both sides of the transmission block.

[0008] Preferably, a roller frame is provided on the side of the trapezoidal frame away from the transmission block, and a movable plate is installed on the upper surface of the roller frame. The outer wall of the movable plate is slidably connected to the inside of the support base.

[0009] Preferably, a limiting block is installed on the outer wall of the movable plate, the outer wall of the limiting block is slidably connected to the inside of the support base, and a magnetic block is installed on the upper surface of the movable plate.

[0010] Preferably, a second magnetic block is provided on the side of the first magnetic block away from the support base, the second magnetic block and the first magnetic block are magnetically repelled, and a cleaning rack is installed on the outer wall of the second magnetic block.

[0011] Preferably, a support rod is installed on the side of the cleaning frame away from the straightening wheel. The outer wall of the support rod is slidably connected to the inside of the support base. One end of a spring is fixedly connected to the outer wall of the support rod, and the other end of the spring is fixedly connected to the outer wall of the support base.

[0012] Preferably, one end of a telescopic rod is fixedly connected to the lower surface of the U-shaped plate, and the other end of the telescopic rod is fixedly connected to the upper surface of the I-shaped frame. A threaded groove is provided inside the I-shaped frame, and a concave ring is threaded to the inner wall of the threaded groove.

[0013] Preferably, the lower surface of the concave ring is disposed on the upper surface of the I-shaped frame, and a convex ring is disposed inside the concave ring. A spring is fixedly connected between the convex ring and the U-shaped plate.

[0014] Preferably, a push block is slidably connected inside the concave ring, and a slide rod is fixedly connected to the outer wall of the push block, with the outer wall of the slide rod slidably connected inside the concave ring.

[0015] Preferably, a trapezoidal block is installed on the upper surface of the slide rod, the outer wall of the trapezoidal block penetrates the interior of the concave ring and is inserted into the interior of the convex ring, and one end of a spring three is fixedly connected to the lower surface of the trapezoidal block, and the other end of the spring three is fixedly connected to the interior of the concave ring.

[0016] Working principle: The guide frame and guide frame one initially limit and constrain the trajectory of the drawn metal wire. When the wire passes through the heating sleeve, it is softened by heat, eliminating the residual stress generated during the drawing process, and continues to move towards the support. The guide frames two on both sides constrain the trajectory of the wire entering and exiting the straightening rollers. After passing through multiple straightening rollers, the wire is straightened. The adjustment mechanism adjusts the distance between the straightening rollers on both sides and the middle straightening roller to adjust the straightening force applied to the wire.

[0017] This invention provides an adjustable-angle heating and straightening mechanism for wire drawing equipment. It has the following beneficial effects: 1. After the angle is adjusted by the support base and straightening wheel, the distance between multiple straightening wheels can be adjusted by the adjustment mechanism to change the bending path and stress state of the wire when passing through the straightening wheel group, so that the wire forms different degrees of reverse bending during the straightening process. At the same time, it can be flexibly adjusted according to the wire with different diameters or degrees of bending, thereby improving the stability and adaptability of the straightening effect.

[0018] 2. This invention uses a motor to drive a bidirectional lead screw, which moves the transmission block and trapezoidal frame to a suitable position. After the roller frame lifts the moving plate and magnetic block one, the magnetic block one and magnetic block two repel each other, causing the cleaning frame to move towards the straightening wheel. During this process, it comes into contact with the outer wall of the straightening wheel. A cleaning brush can be installed on the outer wall of the cleaning frame to clean the debris remaining after the straightening wheel has straightened the wire, preventing debris from accumulating or adhering and affecting the contact state between the straightening wheel and the wire, thereby reducing scratches on the wire surface caused by debris.

[0019] 3. By rotating the concave ring, the convex and concave rings move up and down under the action of the threaded groove, adjusting the distance between the U-shaped plate and the convex ring, thereby changing the extension and contraction of the second spring, and thus adjusting the clamping force of the straightening wheel on the metal wire, so that the straightening wheel fits the wire surface with moderate and stable pressure.

[0020] 4. In this invention, pressing the push block causes the trapezoidal block to move downwards via the slide rod, compressing the spring three. After the trapezoidal block slides out of the interior of the convex ring, it no longer limits the convex ring, allowing it to accommodate the rotation of the concave ring. After the concave ring has rotated, the push block is released, and the spring three causes the trapezoidal block to limit the convex ring, preventing the convex ring from loosening and rotating due to vibration during equipment operation, thus affecting the use of the spring two.

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

[0024] Please see the appendix Figure 1 - Appendix Figure 4This invention provides an adjustable-angle heating and straightening mechanism for a wire drawing device, comprising a base 1, a guide frame 2 mounted on the outer wall of the base 1, a guide frame 3 mounted on the upper surface of the base 1, a heating sleeve 4 mounted on the upper surface of the base 1 via a support block, a support seat 5 hinged to the inside of the base 1 via a rotating shaft, guide frames 6 mounted on both sides of the support seat 5, a hydraulic rod 7 mounted on the upper surface of the base 1 via a short block, a fixed frame 8 rotatably connected to the output end of the hydraulic rod 7 via a rotating shaft, the inside of the fixed frame 8 mounted on the outer wall of the support seat 5, an I-shaped frame 9 slidably connected to the inside of the support seat 5, a U-shaped plate 10 slidably connected to the outer wall of the I-shaped frame 9, a straightening wheel 11 rotatably connected to the inner side of the U-shaped plate 10, and an adjustment mechanism 12 provided inside the support seat 5.

[0025] Specifically, by Figure 3 It can be seen that the straightening wheels 11 inside the support base 5 are arranged opposite each other in the upper and lower directions, which facilitates the straightening of the wire passing through the straightening wheels 11. Since the connection structure of the upper and lower straightening wheels 11 is the same, only the adjusting component of the lower straightening wheel 11 of the support base 5 is described. Figure 1 It is known that the upper surface of the base 1 is equipped with conventional control components for controlling the use of the drive components. The heating sleeve 4 adopts a surrounding hollow structure with heating elements arranged inside to circumferentially heat and soften the passing metal wire. The guide frames 6 on both sides of the support 5 deflect synchronously with the straightening wheel 11, always maintaining coaxiality with the straightening wheel 11 and constraining the trajectory of the wire entering and exiting the straightening wheel 11. When the hydraulic rod 7 drives the fixed frame 8 and the support 5 to move upward, the rotating components on both sides of the hydraulic rod 7 lift the right side of the support 5, allowing the support 5 and the straightening wheel 11 to be angled. The self-locking of the hydraulic rod 7 ensures the stability of the support 5 after rotation. The adjustment mechanism 12 allows the spacing of multiple straightening wheels 11 to be adjusted, enabling the straightening mechanism to be flexibly adjusted according to wires of different diameters, materials and degrees of curvature.

[0026] Please see the appendix Figure 2 - Appendix Figure 5 The adjustment mechanism 12 includes a motor 121. The outer wall of the motor 121 is installed inside the support base 5. A bidirectional lead screw 122 is fixedly installed at the output end of the motor 121. A transmission block 123 is threadedly connected to the outer wall of the bidirectional lead screw 122. The upper surface of the transmission block 123 is installed on the lower surface of the I-shaped frame 9. Trapezoidal frames 124 are installed on both sides of the transmission block 123.

[0027] Specifically, the motor 121 adopts a self-locking type as in the prior art to self-lock the rotation of the bidirectional lead screw 122. A short block is provided on the side of the bidirectional lead screw 122 away from the motor 121, and the short block is fixed to the lower surface of the support base 5, thereby supporting the rotation of the bidirectional lead screw 122. The transmission block 123 forms an integral part with the I-shaped frame 9. Under the rotation of the bidirectional lead screw 122, the I-shaped frames 9 on both sides and their connecting parts are driven to move.

[0028] Please see the appendix Figure 5 A roller frame 13 is provided on the side of the trapezoidal frame 124 away from the transmission block 123. A movable plate 14 is installed on the upper surface of the roller frame 13, and the outer wall of the movable plate 14 is slidably connected to the inside of the support base 5.

[0029] Specifically, the movement of the movable plate 14 is limited by the interior of the support base 5, and the outer wall of the movable plate 14 is provided with a U-shaped block and is located in a suitable position so that the range of the movable plate 14 is limited when it moves downward under its own weight, so that the roller frame 13 and the trapezoidal frame 124 cooperate, and the movable plate 14 moves upward under the action of the roller frame 13 through the inclined surface of the trapezoidal frame 124.

[0030] Please see the appendix Figure 4 - Appendix Figure 6 A limit block 15 is installed on the outer wall of the movable plate 14. The outer wall of the limit block 15 is slidably connected to the inside of the support base 5. A magnetic block 16 is installed on the upper surface of the movable plate 14.

[0031] Specifically, by Figure 6 It is known that the support base 5 has a groove inside for the sliding of the limiting block 15, thereby preventing the movement of the moving plate 14 from deviating and constraining the movement trajectory of the magnetic block 16.

[0032] Please see the appendix Figure 4 - Appendix Figure 6 A second magnetic block 17 is provided on the side of the first magnetic block 16 away from the support base 5. The second magnetic block 17 and the first magnetic block 16 are magnetically repelled. A cleaning frame 18 is installed on the outer wall of the second magnetic block 17. A support rod 19 is installed on the side of the cleaning frame 18 away from the straightening wheel 11. The outer wall of the support rod 19 is slidably connected to the inside of the support base 5. One end of a spring 20 is fixedly connected to the outer wall of the support rod 19, and the other end of the spring 20 is fixedly connected to the outer wall of the support base 5.

[0033] Specifically, with the initial position of magnetic block 16 below magnetic block 17, magnetic block 16 does not repel magnetic block 17. When magnetic block 16 is moved upward by external force, it repels magnetic block 17, causing magnetic block 17 and cleaning frame 18 to move away from magnetic block 16. A suitable cleaning brush can be installed on the cleaning frame 18. When the cleaning frame 18 moves or resets in the direction of the straightening wheel 11, it can scrape off the attached material on the outer wall of the straightening wheel 11 to reduce the debris remaining on the outer wall of the straightening wheel 11 after straightening. The support rods 19 on both sides of the cleaning frame 18 slide inside the support base 5 to support and limit the movement of the cleaning frame 18. The spring 20 provides the reset force for the cleaning frame 18 after movement. A fan can be installed on the lower side of the support base 5 to clean the debris on the threaded parts to reduce the impact of debris falling from the straightening wheel 11 on the threaded parts.

[0034] Please see the appendix Figure 5 - Appendix Figure 8 One end of a telescopic rod 21 is fixedly connected to the lower surface of the U-shaped plate 10, and the other end of the telescopic rod 21 is fixedly connected to the upper surface of the I-shaped frame 9. A threaded groove 22 is provided inside the I-shaped frame 9, and a concave ring 23 is threadedly connected to the inner wall of the threaded groove 22. The lower surface of the concave ring 23 is set on the upper surface of the I-shaped frame 9, and a convex ring 24 is provided inside the concave ring 23. A spring 25 is fixedly connected between the convex ring 24 and the U-shaped plate 10.

[0035] Specifically, the telescopic rod 21 limits the downward movement of the U-shaped plate 10 and its connecting parts, preventing excessive offset of the U-shaped plate 10 and affecting its vertical movement. Figure 8 It is known that a threaded groove 22 is provided in the middle of the I-shaped frame 9, and the threaded groove 22 cooperates with the concave ring 23 so that the concave ring 23 can move up and down under the action of the threaded groove 22. The thread between the threaded groove 22 and the concave ring 23 ensures that the position of the concave ring 23 is stable after rotation. The convex ring 24 changes the extension and contraction of the spring 25 under the push of the concave ring 23, thereby adjusting the clamping force of the U-shaped plate 10 and its connecting parts on the wire. The cooperation between the concave ring 23 and the convex ring 24 makes it easy for the convex ring 24 to move with the concave ring 23.

[0036] Please see the appendix Figure 8 - Appendix Figure 10 A push block 26 is slidably connected inside the concave ring 23, and a slide rod 27 is fixedly connected to the outer wall of the push block 26. The outer wall of the slide rod 27 is slidably connected inside the concave ring 23. A trapezoidal block 28 is installed on the upper surface of the slide rod 27. The outer wall of the trapezoidal block 28 penetrates the interior of the concave ring 23 and is inserted into the interior of the convex ring 24. One end of a spring 29 is fixedly connected to the lower surface of the trapezoidal block 28, and the other end of the spring 29 is fixedly connected to the interior of the concave ring 23.

[0037] Specifically, the upward and downward movement of the push block 26, slide rod 27, and trapezoidal block 28 is offset and limited by the interior of the concave ring 23. The push block 26, located outside the concave ring 23, facilitates the transmission of the slide rod 27 and trapezoidal block 28. Figure 9 It is known that the convex ring 24 has multiple grooves on the side near the concave ring 23, which are used for the trapezoidal block 28 to be inserted into or slide out of the interior of the convex ring 24, and to make the convex ring 24 adapt to the rotation of the concave ring 23. Through the setting of the spring 3 29, the trapezoidal block 28 is provided with an upward force under normal conditions to ensure that the convex ring 24 will not rotate unexpectedly.

[0038] Workflow: The drawn wire is passed through the interior of the guide frame 2 and continues to move towards the support base 5. After being set by the first guide frame 3, the wire's trajectory into the heating sleeve 4 is constrained. After the wire is heated and softened by the heating sleeve 4, it is guided by the second guide frame 6 on the left side of the support base 5. Multiple straightening wheels 11 are set inside the support base 5 and are staggered to straighten the heated wire. The straightened wire is then discharged through the second guide frame 6 on the right side of the support base 5 and collected at an external collection device. The left side of the support base 5 is hinged to the base 1 via a pivot, while the right side of the support base 5 is driven by a hydraulic rod 7 to push the fixed frame 8, causing the support base 5 to rotate. The two ends of the hydraulic rod 7 are connected to the base 1 and the fixed frame 8 via pivots, respectively, to adapt to the rotation of the support base 5 and adjust the angle of the straightening components to meet the straightening requirements of the wire.

[0039] Before straightening, the motor 121 drives the bidirectional lead screw 122 to rotate. The position of the straightening wheel 11 located in the middle of the support base 5 remains unchanged. The straightening wheels 11 on both sides are driven by the threads of the transmission block 123 and the bidirectional lead screw 122 to move synchronously towards the center of the bidirectional lead screw 122. After the transmission block 123 moves to the appropriate position, the distance between the straightening wheels 11 on both sides and the straightening wheel 11 in the middle is adjusted.

[0040] When adjusting the spacing of the straightening wheels 11, the bidirectional lead screw 122 can continue to rotate, causing the straightening wheels 11 on both sides to converge with the straightening wheel 11 in the middle. When the bidirectional lead screw 122 drives the transmission block 123 to move to the appropriate position, as the trapezoidal frame 124 moves, the moving plate 14 moves upward by being pushed against by the roller frame 13. The movement of the moving plate 14 is limited by the limit block 15. After the magnetic block 16 moves upward with the moving plate 14 to the appropriate position, the magnetic block 16 aligns with the magnetic block 17. The cleaning frame 18 and support rod 19 are pushed towards the straightening wheel 11, and the spring 20 is squeezed. A suitable cleaning pad or cleaning brush can be installed on the outer wall of the cleaning frame 18. The cleaning frame 18 and its connecting parts are provided on both sides of the support base 5, which facilitates the contact between the cleaning brush and the straightening wheel 11, thereby cleaning the outer wall of the straightening wheel 11. When the trapezoidal frame 124 returns to its original position with the transmission block 123, the cleaning frame 18 returns to its original position under the elastic force of the spring 20.

[0041] When in use, the straightening wheel 11, through the setting of spring 25, allows the straightening wheel 11 and U-shaped plate 10 to be cushioned downwards, making it easy for the straightening wheel 11 to produce a slight displacement when subjected to instantaneous tension changes, thereby absorbing the impact force. First, press the push block 26, which drives the trapezoidal block 28 to move downwards through the slide rod 27, compressing the spring 29. After the trapezoidal block 28 slides out of the interior of the convex ring 24, it no longer limits the convex ring 24. By rotating the concave ring 23, it passes through its interior and the threaded groove 2 The thread between 2 causes the concave ring 23 to move upward, preventing the convex ring 24 from rotating synchronously with the concave ring 23. This causes the spring 25 to deform, and the concave ring 23 drives the convex ring 24 to a suitable position. Then, the distance between the U-shaped plate 10 and the convex ring 24 is adjusted, causing the spring 25 to generate a corresponding extension and contraction. This, in turn, adjusts the clamping force of the straightening wheel 11 on the metal wire. At the same time, the push block 26 is released, and the trapezoidal block 28 limits the convex ring 24 under the elastic force of the spring 3 29.
