Description

Technical Field

[0001] This invention relates to the field of oxygen-free copper wire processing technology, specifically to a micro-fine oxygen-free copper wire drawing anti-breakage guide buffer device. Background Technology

[0002] In existing technologies, high-speed drawing of oxygen-free copper raw materials into fine copper wires is achieved through a gradient decrease in die aperture, full-process lubrication and cooling, and timely inter-pass annealing.

[0003] Existing micro-copper wire drawing process anti-breakage guide buffer devices typically use spring or pneumatic buffers in conjunction with guide wheel sets to automatically absorb impact and compensate for speed fluctuations when the copper wire tension is abnormal.

[0004] During the high-speed drawing of fine oxygen-free copper wire, when the tension fluctuates instantaneously due to the start-stop, slippage, or sudden changes in winding of the take-up roller, the high rigidity required for guidance and the low rigidity required cannot be simultaneously achieved in the same mechanical structure. This results in an inherent delay in the buffer response of traditional devices, which cannot complete the effective energy release before the tension peak reaches the weak section of the wire. Consequently, the wire breaks due to the impact of surface tension, leading to a deterioration in the continuity of drawing production and a decrease in the yield of finished products. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a micro-fine oxygen-free copper wire pull-out anti-breakage guiding buffer device, which senses tension fluctuations and actively shortens the tension transmission path to achieve adaptive balance buffering and eliminate instantaneous impact breakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof.

[0034] Example 1

[0035] like Figure 1 - Figure 11 As shown, this embodiment provides a micro-fine oxygen-free copper wire pulling anti-breakage guide buffer device, including a pulling structure 100, including a main body 101, a wire outlet port 102 fixedly disposed on the main body 101, and a guide wheel 103 fixedly disposed on the main body 101;

[0036] Also includes:

[0037] The buffer structure 200 includes a support plate 201, a partition plate 202, a buffer groove 203, a floating plate 204, a sliding groove 205, an angle deflector 206, and an elastic buffer 207. The support plate 201 is fixedly disposed below the guide wheel 103, the partition plate 202 is fixedly disposed on the support plate 201, the buffer groove 203 is disposed on the partition plate 202, the floating plate 204 is movably disposed in the buffer groove 203, the sliding groove 205 is disposed on the floating plate 204, the angle deflector 206 is fixedly disposed on the partition plate 202, and the elastic buffer 207 is fixedly disposed on the floating plate 204.

[0038] And, the guide structure 300 includes an L-tooth plate 301, a lower cantilever 302, a wheel axle 306, a connecting shaft 303, a lower guide wheel 307, and a synchronization component 308. The L-tooth plate 301 is slidably disposed on the slide groove 205, the lower cantilever 302 is fixedly disposed on the L-tooth plate 301, the wheel axle 306 is fixedly disposed on the lower cantilever 302, the connecting shaft 303 is rotatably disposed inside the lower cantilever 302 and the wheel axle 306 respectively, the lower guide wheel 307 is rotatably disposed on the wheel axle 306, and the synchronization component 308 is fixedly disposed at the top of the connecting shaft 303.

[0039] The floating plate 204 has a recessed groove 2041, inside which a stepper motor 208 is fixedly installed. A first gear 2081 is fixedly installed at the output end of the stepper motor 208, and the first gear 2081 meshes with an L-shaped gear plate 301. The stepper motor 208 drives the first gear 2081 to mesh with the L-shaped gear plate 301, thereby achieving active control of the position of the lower cantilever 302.

[0040] The angle deflection component 206 includes a support plate 2061 fixedly mounted on the support plate 201, a top block 2065 fixedly mounted on the floating plate 204, and an angle sensor 2062 fixedly mounted on the support plate 2061 and located on the side of the floating plate 204. The top block 2065 transmits the deflection displacement of the floating plate 204 to the angle sensor 2062, realizing real-time detection and signal conversion of tension fluctuations.

[0041] The angle sensor 2062 has a fixed rotating shaft 2063 at its output end. A deflection rod 2064 is fixedly installed at the end of the rotating shaft 2063 away from the angle sensor 2062. The deflection rod 2064 is located on the side of the top block 2065. The linear displacement of the top block 2065 is converted into the rotation angle of the rotating shaft 2063 by the deflection rod 2064, which facilitates the detection by the angle sensor 2062.

[0042] The elastic buffer 207 includes two extension blocks 2071 fixedly mounted on the floating plate 204, two fixed posts 2072 fixedly mounted on the floating plate and located on the sides of the extension blocks 2071, an arc-shaped spring piece 2073 movably mounted on the fixed posts 2072, and a protrusion 2074 fixedly mounted on the two extension blocks 2071. The arc-shaped spring piece 2073 and the protrusion 2074 cooperate to provide elastic support and a deflection fulcrum for the floating plate 204, and limit the floating range of the floating plate 204 in the buffer groove 203.

[0043] The fine oxygen-free copper wire is output from the output port 102. After passing through the guide roller 103, it first winds around the upper guide roller 310, and then winds around the lower guide roller 307 in an S-shaped winding manner. That is, the winding method of the wire between the upper guide roller 310 and the lower guide roller 307 is S-shaped. The wire enters from the left side of the upper guide roller 310, winds around the top right of the upper guide roller 310 to the lower left exit, and then enters from the left side of the lower guide roller 307, winds around the bottom of the lower guide roller 307 to the lower right exit. Thus, an S-shaped wire path with left and right opposite directions and up and down opposite directions is formed between the upper guide roller 310 and the lower guide roller 307. Finally, it is connected to the take-up roller. The upper guide roller 310 and the lower guide roller 307 are located between the guide roller 103 and the drive shaft 104. When the drive shaft 104 drives the take-up roller to rotate, the upper guide roller 310 and the lower guide roller 307 are used to guide the fine copper wire.

[0044] The S-shaped winding between the upper guide wheel 310 and the lower guide wheel 307 creates a wrap angle between the upper and lower guide wheels 307, increasing the friction between the wire and the guide wheels, ensuring the stability of tension transmission, and also quickly compensating for the additional tension caused by the downward movement of the lower cantilever 302 when the diameter of the lower guide wheel 307 decreases, thus comprehensively ensuring timely response and buffering of tension fluctuations during high-speed drawing.

[0045] The floating plate 204 is separated from the deepest part of the buffer groove 203 by the protrusion 2074 on the extension block 2071, so that the floating plate 204 can float freely in the buffer groove 203 by means of the arc-shaped spring piece 2073. The arc-shaped spring piece 2073 on the side of the extension block 2071 is installed on the floating plate 204 by the fixing post 2072. The highest point of the arc-shaped spring piece 2073 abuts against the side wall of the buffer groove 203, and this contact point provides indirect contact support for the floating plate 204.

[0046] When the wire tension between the take-up roller and the lower guide roller 307 is within the normal range, the floating plate 204 maintains a balanced position under the elastic support of the arc-shaped spring plate 2073, the lower cantilever 302 is fixed at a certain position on the slide groove 205 by the L-tooth plate 301, the lower guide roller 307 remains stable, and the wire passes smoothly through the upper guide roller 310 and the lower guide roller 307.

[0047] When the take-up roller starts or stops, slips, or experiences a sudden change in winding, causing an instantaneous increase in the tension of the wire between the lower guide roller 307 and the take-up roller, the tension is transmitted through the lower guide roller 307 to the lower cantilever 302. The lower cantilever 302 then transmits the tension to the floating plate 204. After being subjected to tension, the floating plate 204 deflects at a small angle with the contact point between the arc-shaped spring piece 2073 and the side wall of the buffer groove 203 as the fulcrum. When the floating plate 204 deflects, the top block 2065, which is fixedly mounted on the floating plate 204, moves with the floating plate 204. The top block 2065 pushes the deflection rod 2064 located on the side of the top block 2065. The deflection rod 2064 rotates around the rotating shaft 2063. The rotating shaft 2063 transmits the rotation angle of the deflection rod 2064 to the angle sensor 2062. The angle sensor 2062 detects the deflection angle in real time and outputs an electrical signal.

[0048] Angle sensor 2062 transmits electrical signals to the controller of stepper motor 208. Stepper motor 208 drives the output end to rotate according to the received signal. The working principle of this part is prior art and can be clearly understood by those skilled in the art, so it will not be described in detail here. The first gear 2081, which is fixedly set on the output end of stepper motor 208, rotates synchronously with stepper motor 208. The first gear 2081 meshes with L-tooth plate 301. When the first gear 2081 rotates, it drives L-tooth plate 301 to slide downward in slide groove 205. The lower cantilever 302, which is fixedly set on L-tooth plate 301, moves downward with L-tooth plate 301. The lower guide wheel 307, which is rotatably set on the wheel axle 306 of lower cantilever 302, moves downward accordingly. The distance between lower guide wheel 307 and take-up roller decreases, thereby buffering the wire tension between lower guide wheel 307 and take-up roller.

[0049] When the tension between the take-up roller and the lower guide wheel 307 returns to normal, the arc-shaped spring 2073 applies a restoring elastic force to the floating plate 204 through the fixed column 2072, pushing the floating plate 204 back to the initial equilibrium position. During the return of the floating plate 204, the top block 2065 drives the deflection rod 2064 to rotate, the angle sensor 2062 detects the angle change, and the stepper motor 208 rotates in the opposite direction. The working principle of this part is the prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here. The first gear 2081 drives the L-tooth plate 301 to slide upward in the slide groove 205, and the lower cantilever 302 and the lower guide wheel 307 return to the initial position, and the entire device returns to the normal tension state.

[0050] In summary, this method enables rapid and precise adaptive buffering control of instantaneous tension fluctuations during the production of fine copper wires. It dissipates tension peaks in advance, eliminates secondary tension impacts and wire rebound disturbances, effectively avoids wire breakage caused by sudden tension changes, stabilizes the tension state throughout the drawing process, significantly improves the continuity and stability of high-speed drawing production, and greatly increases the yield of finished products.

[0051] Furthermore, an upper cantilever 309 is fixedly mounted on the spacer 202. An upper guide wheel 310 is rotatably connected to the outer surface of the axle 306 of the upper cantilever 309. A wire groove 3071 is provided on the surface of the lower guide wheel 307, and three circumferentially arranged fixing grooves 3072 are provided on the surface of the lower guide wheel 307 and on the side of the axle 306. The upper cantilever 309 and the upper guide wheel 310 fix the wire entry path, and the wire groove 3071 and fixing grooves 3072 on the lower guide wheel 307 provide guidance and a mounting base for subsequent wheel diameter adjustment.

[0052] Furthermore, a synchronizing gear plate 304 is fixedly installed on the recessed groove 2041, and a second gear 305 is meshed on the synchronizing gear plate 304. The second gear 305 is fixedly installed on the connecting shaft 303. Through the meshing of the synchronizing gear plate 304 and the second gear 305, the linear motion of the lower cantilever 302 is converted into the rotational motion of the connecting shaft 303.

[0053] Furthermore, the synchronization assembly 308 includes a synchronization plate 3081 fixedly mounted on the top of the connecting shaft 303, an arc-shaped groove 3082 disposed on the synchronization plate 3081 and distributed circumferentially, and a transmission rod 3083 slidably disposed within both the fixed groove 3072 and the arc-shaped groove 3082. The arc-shaped groove 3082 on the synchronization plate 3081 engages with the fixed groove 3072, guiding the transmission rod 3083 to slide along the fixed groove 3072 as the connecting shaft 303 rotates.

[0054] Furthermore, a top plate 3084 is fixedly installed on the transmission rod 3083 and located within the guide groove 3071. An elastic ring 3085 is attached to the top plate 3084, and an outer ring 3086 is attached to the elastic ring 3085. Through the layered and attached structure of the top plate 3084, the elastic ring 3085, and the outer ring 3086, the sliding of the transmission rod 3083 is converted into the elastic contraction and expansion of the diameter of the lower guide wheel 307.

[0055] Furthermore, a power shaft 104 is rotatably mounted on the main body 101, located below the support plate 201, and a sealing plate 2031 is fixedly mounted on the floating plate 204. The power shaft 104 drives the take-up roller to rotate, and the sealing plate 2031 restricts the position of the floating plate 204 in the buffer groove 203 to prevent the floating plate 204 from falling off.

[0056] As the lower cantilever 302 moves downward, the second gear 305, fixedly mounted on the connecting shaft 303, rolls along the synchronous gear plate 304, fixedly mounted on the hidden groove 2041. The second gear 305 drives the connecting shaft 303 to rotate inside the lower cantilever 302 and the axle 306. The rotating connecting shaft 303 drives the synchronous plate 3081, fixedly mounted on the top of the connecting shaft 303, to rotate. The arc-shaped groove 3082 on the synchronous plate 3081 rotates with the synchronous plate 3081. The transmission rod 3083 slides along the fixed groove 3072 under the push of the arc-shaped groove 3082. When the transmission rod 3083 slides, the top piece 3084, fixedly mounted on the transmission rod 3083 and located in the wire groove 3071, retracts with the transmission rod 3083 in the wire groove 3071. The three top pieces 3084 move away from the center of the elastic ring 3085. After retraction, the elastic ring 3085, which is attached to the top plate 3084, loses the radial support of the top plate 3084. The elastic ring 3085 drives the outer ring 3086, which is attached to the elastic ring 3085, to contract inward. The bottom diameter of the wire groove 3071 on the surface of the lower guide wheel 307 decreases accordingly, and the wheel diameter of the lower guide wheel 307 shrinks. The outer ring 3086 is made of polyurethane material, which can ensure stable elasticity and wear resistance during frequent contraction and expansion. At the same time, the coefficient of friction between the polyurethane material and the fine oxygen-free copper wire is moderate. It can provide sufficient friction to prevent the wire from slipping in the wire groove 3071, and will not cause scratches or copper powder to fall off the wire surface due to excessive friction. Thus, the surface quality of the wire is always protected during the dynamic change of the wheel diameter, and secondary wire breakage is avoided due to excessively hard guide wheel material or improper friction.

[0057] After the diameter of the lower guide roller 307 is reduced, the wrap angle path length of the wire on the lower guide roller 307 becomes shorter, which is equivalent to shortening the wire length between the upper guide roller 310 and the lower guide roller 307. This offsets the additional tension caused by the downward movement of the lower cantilever 302, which increases the distance between the upper guide roller 310 and the lower guide roller 307. This prevents the wire between the upper guide roller 310 and the lower guide roller 307 from being overstretched. At the same time, when the lower guide roller 307 actively moves closer to the take-up roller, the wrap angle tension of the wire between the upper and lower guide rollers 307 is dynamically locked, so that the tension peak is converted into frictional dissipation between the guide roller and the wire before reaching the weak section of the wire, thus achieving tension suppression through reverse displacement and positive buffering.

[0058] As the lower cantilever 302 moves upward, the second gear 305 rolls in the opposite direction along the synchronous gear plate 304, the connecting shaft 303 rotates in the opposite direction, the synchronous plate 3081 drives the arc groove 3082 to return to its original position, the transmission rod 3083 slides in the opposite direction along the fixed groove 3072, the top plate 3084 pushes the elastic ring 3085 outward again, the elastic ring 3085 drives the outer ring 3086 to expand, the lower guide wheel 307 wheel diameter returns to its initial state, the entire device returns to the normal tension state, and the sealing plate 2031 is fixedly set on the floating plate 204 to close the opening of the buffer groove 203 after the floating plate 204 is installed, preventing the floating plate 204 from falling out of the buffer groove 203.

[0059] In summary, by sensing wire tension fluctuations and actively shortening the transmission path of wire tension between the upper guide roller 310 and the lower guide roller 307, and between the lower guide roller 307 and the take-up roller, the contact arc between the wire and the guide rollers is dynamically adjusted to compensate for the additional tension caused by the path change. This achieves adaptive balance and guidance buffering of tension during high-speed drawing without stopping the machine, solving the problem of frequent wire breakage caused by rigid conflict and response delay in traditional devices, and significantly improving production continuity and finished product quality consistency.
