Description

Technical Field

[0001] The invention relates to the technical field of copper material straightening, in particular to a continuous straightening device for copper wire production. Background Art

[0002] Copper materials refer to various shapes made of pure copper or copper alloys, including copper plates, copper rods, copper tubes, copper strips, copper wires, copper bars and copper materials. When copper rods and copper tubes are processed, the roller body may bend, and a straightening device is usually used to correct the roller body.

[0003] For example, the Chinese authorized patent with the announcement number CN218692747U discloses a copper straightening device, which includes a base plate, a bracket installed on the top of the base plate, a first mounting seat installed in the middle of the top of the base plate, a second mounting seat arranged horizontally at the top end of the bracket, a collection box installed at the rear end of the base plate, and a second rotating wheel installed at the rear end of the right side of the first mounting seat. The copper straightening device is provided with a connecting belt, a first rotating wheel, a second rotating wheel, a rotating motor and a feed roller. The copper material is placed on the feed roller, and the rotating motor is started to drive the second rotating wheel to rotate, which also causes the feed roller to start rotating. The first rotating wheel and the second rotating wheel are connected by a connecting belt, thereby driving the first rotating wheel and the lower pressure roller to rotate, thereby feeding the copper material between the lower pressure roller and the upper pressure roller. The copper material is straightened by the lower pressure roller and the upper pressure roller, achieving the purpose of straightening the copper material while conveying it. The automation efficiency is high, and the problem of the time-consuming and labor-intensive feeding structure is solved.

[0004] However, the above-mentioned copper straightening device cannot continuously straighten the copper wire during the straightening process, so that the copper wire can only obtain a single or intermittent straightening force when passing through the lower pressure roller and the upper pressure roller. If the copper wire has complex bends, kinks and other problems, a single extrusion is difficult to completely eliminate the deformation, which may easily lead to local residual curvature of the copper wire and cause the straightness to fail to meet the standard. In addition, during the straightening process, it is impossible to perform a 360° rolling operation on the outer surface of the copper wire, which means that pressure can only be applied in a fixed direction and multi-dimensional bending cannot be handled. In particular, for copper wire with spiral twists or irregular deformations, it is difficult to achieve all-round straightening, resulting in low precision of the finished product, which is difficult to meet the needs of industries such as electronics and precision instruments that have strict requirements on wire quality. Summary of the Invention

[0005] The object of the present invention is to provide a continuous straightening device for copper wire production, so as to solve the problem proposed in the above-mentioned background technology that the copper wire cannot be straightened continuously during the straightening process, which easily leads to local residual curvature of the copper wire and causes the straightness to fail to meet the standard.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. Multi-stage coordinated straightening to improve straightening accuracy Through the two-stage linkage design of the continuous straightening mechanism and the traction roller pressing mechanism, the copper wire can be treated with "primary straightening + secondary fine straightening": The continuous straightening mechanism forms a multi-angle pressure coverage through the concave-convex interlocking structure of the Λ-shaped roller belt and the V-shaped roller belt, which can simultaneously correct the straightness of the copper wire and eliminate complex deformations such as local bending and torsion; The traction roller pressing mechanism drives the ball bearing to perform 360° circumferential rolling through the rotating tube, and cooperates with the guiding shaping of the tapered combing hole to achieve all-round dynamic straightening of the outer surface of the copper wire, ensuring that the wire achieves ideal straightness and flatness in all directions.

[0019] 2. Adaptive adjustment and stable clamping, compatible with multiple specifications of wire Adjustable pressure structure: The electric push rod drives the Λ-shaped frame to drive the threaded rod to rise and fall, adjusting the depth of the Λ-shaped roller belt embedded in the V-shaped roller belt to adapt to copper wires of different diameters or hardness; the handwheel locking structure can fix the position of the threaded rod to ensure stable pressure during the straightening process.

[0020] Elastic buffering and guiding design: The U-shaped frame cooperates with the guide groove through the guide block, sliding stably in the sliding groove; the connecting column and rectangular spring form an elastic support, allowing the ball bearing to adaptively fit the copper wire surface. It can not only provide sufficient straightening pressure, but also absorb vibration through elastic deformation to avoid damage to the wire surface, and is compatible with the straightening needs of copper wires with different tolerances.

[0021] 3. Efficient transmission and stable traction to ensure continuous production Synchronous transmission system: The first transmission column and the second transmission column rotate synchronously through the first transmission disc, the second transmission disc and the transmission belt. The relative movement of the Λ-shaped roller belt and the V-shaped roller belt forms a clamping force similar to the engagement of gears, ensuring stable engagement and continuous traction of the copper wire. Rotating roller pressing mechanism: The third reduction motor drives the rotating tube to rotate 360° through the transmission belt, driving the ball bearing to perform full-circumferential rolling straightening on the outer surface of the copper wire. Combined with the traction effect of the first connecting disk and the second connecting disk engaged by the gears, the continuity and stability of the straightening process are achieved, thereby improving production efficiency.

[0022] 4. Compact structure and integrated functions to optimize equipment performance The modular design of the first and second connection boxes integrates traction, straightening, rolling and other functions into one, reducing the risk of deviation in the wire transmission path; Auxiliary structures such as guide blocks and top contact plates ensure that the roller belt remains precisely fitted. The coordination of ball bearings and combing holes reduces friction between the wire and the equipment, lowers energy consumption and improves the consistency of straightening quality.

[0023] In summary, the device achieves high-precision and high-efficiency straightening of copper wire through the synergistic effect of technical features such as multi-stage straightening, adaptive adjustment, efficient transmission and elastic buffering. It can meet the stringent requirements of wire straightness and surface quality in different production scenarios, and has both practicality and process adaptability.

DETAILED DESCRIPTION

[0026] See also Figures 1-8 , this embodiment provides the following technical solutions: like Figure 1-Figure 2 As shown, a continuous straightening device for copper wire production includes: a first connecting box 1, a plurality of groups of n-shaped frames 102 are fixedly installed on the upper surface of the first connecting box 1, and a continuous straightening mechanism 2 is installed in the plurality of n-shaped frames 102 so that the continuous straightening mechanism 2 can pull the continuously produced copper wire into the traction rolling mechanism 3, and the traction rolling mechanism 3 is fixedly installed on the upper surface of the second connecting box 101, and the second connecting box 101 is fixedly installed at one end of the first connecting box 1. The traction rolling mechanism 3 can perform 360° roller straightening on the outer surface of the pulled-in copper wire, and can achieve a straightened state by subjecting the copper wire to a full-range rolling treatment.

[0027] Through the design of the first connection box 1, the second connection box 101, the continuous straightening mechanism 2 and the traction roller pressing mechanism 3, when in use, the copper wire is placed in the continuous straightening mechanism 2 in the multiple groups of n-shaped frames 102 on the first connection box 1. The continuous straightening mechanism 2 can use a unique transmission structure to tightly bite the copper wire and continuously apply pressure to the copper wire through multi-angle pressure coverage. In this process, the pressure in multiple directions works together to accurately correct the straightness of the copper wire, effectively eliminate the complex deformation problems of the copper wire such as bending and twisting, and preliminarily realize the straightening of the copper wire. The copper wire that has been preliminarily straightened will be smoothly pulled by the continuous straightening mechanism 2 into the traction rolling mechanism 3 fixed on the upper surface of the second connection box 101. After the traction rolling mechanism 3 is started, the outer surface of the copper wire entering it will be subjected to a 360° rolling and straightening operation. This all-round rolling treatment can perform secondary fine correction on the copper wire without missing any possible tiny deformation area, ensuring that the copper wire achieves ideal straightness and surface flatness in all directions, and ultimately produces high-precision, high-quality straightened copper wire to meet the stringent requirements of copper wire quality in different production scenarios.

[0028] like Figure 3-Figure 6 As shown, the continuous straightening mechanism 2 includes a traction block 205 and multiple sets of second transmission columns 207. The traction block 205 is slidably installed in the traction groove 103. The traction groove 103 is opened at both ends of the N-shaped frame 102. A first transmission column 211 is rotatably installed between each two sets of laterally opposite traction blocks 205. Two sets of conveyor belts 216 are sheathed on the outer surfaces of the multiple sets of first transmission columns 211. A V-shaped roller belt 206 is fixedly installed between the two sets of conveyor belts 216 by bolts. Among them, multiple groups of second transmission columns 207 are rotatably installed in the first connecting box 1 at equal intervals, and the outer surface of each group of second transmission columns 207 is sleeved with two groups of conveyor belts 216, and a V-shaped roller belt 208 is fixedly installed between the two groups of conveyor belts 216 by bolts. The V-shaped embedded groove of the V-shaped roller belt 208 is used to accommodate the copper wire, and the concave part of the V-shaped roller belt 208 and the convex part of the Λ-shaped roller belt 206 are in an embeddable matching structure, so that the V-shaped roller belt 208 and the Λ-shaped roller belt 206 form an interlocking pressure structure for the copper wire. Through the combined design of Λ shape and V shape, multi-angle pressure coverage can be formed on the outer surface of the copper wire, thereby realizing the correction of the straightness of the copper wire and the elimination of complex deformations such as local bending and torsion.

[0029] One group of first transmission columns 211 is fixedly connected to the output shaft of the first reduction motor 209, and the second transmission column 207 is fixedly connected to the output shaft of the second reduction motor 210, so that the first reduction motor 209 and the second reduction motor 210 can respectively drive the first transmission column 211 and the second transmission column 207 to rotate relative to each other, so that the first transmission column 211 and the second transmission column 207 can drive the Λ-shaped roller belt 206 and the V-shaped roller belt 208 set on the outer surface to perform relative transmission, allowing them to achieve biting of the copper wire.

[0030] The first transmission disc 212 and the second transmission disc 213 are fixedly mounted on one end of the multiple sets of first transmission columns 211 and the second transmission columns 207. The outer surfaces of the multiple sets of first transmission discs 212 and the second transmission discs 213 are all covered with transmission belts, so that the multiple sets of first transmission columns 211 and the second transmission columns 207 can be pulled and rotated synchronously. The upper surfaces of the multiple sets of traction blocks 205 are fixedly mounted with threaded rods 203. The upper ends of the threaded rods 203 pass through the traction grooves 103 to the upper surface of the n-shaped frame 102, and each two sets of transversely opposite A V-shaped frame 202 is fixedly installed between the upper surfaces of the threaded rods 203. The lower surface of the central portion of the V-shaped frame 202 is fixedly connected to the piston rod of the electric push rod 201. The electric push rod 201 is fixedly installed in the N-shaped frame 102, so that the electric push rod 201 can push or pull the traction block 205 to slide up and down in the traction groove 103 through the threaded rods 203. The driven traction block 205 can adjust the depth of the V-shaped roller belt 206 mounted on the outer surface of the first transmission column 211 pressed into the V-shaped roller belt 208 through the lifting operation; Two sets of handwheels 204 are threadedly mounted on the outer surface of each set of threaded rods 203. These two sets of handwheels 204 can respectively engage the upper and lower surfaces of the N-shaped frame 102 to lock the raising and lowering of the threaded rods 203. A V-shaped disc 214 is fixedly mounted on the middle section of the outer surface of the first transmission column 211. The V-shaped disc 214 drives within the V-shaped roller belt 206, thereby maintaining the convex shape of the V-shaped roller belt 206. Among them, a top contact plate 215 is provided between each group of second transmission columns 207, and the top contact plate 215 located between the second transmission columns 207 simultaneously contacts the inner annular surface of the V-shaped roller belt 208, thereby preventing the V-shaped roller belt 208 from collapsing inward due to the rolling pressure of the Λ-shaped roller belt 206.

[0031] Through the design of the electric push rod 201, the Λ-shaped frame 202, the threaded rod 203, the hand wheel 204, the traction block 205, the Λ-shaped roller belt 206, the V-shaped roller belt 208, the first reduction motor 209 and the second reduction motor 210, when in use, the first reduction motor 209 and the second reduction motor 210 can be started together to synchronously drive the first transmission column 211 and the second transmission column 207 to rotate relative to each other, and the first transmission column 211 and the second transmission column 207 that rotate relatively can be fixedly installed at the other end. The first transmission disc 212 and the second transmission disc 213 are driven to rotate synchronously, so that the plurality of first transmission columns 211 and the second transmission columns 207 can respectively drive the conveyor belt 216, between which the Λ-shaped roller belt 206 and the V-shaped roller belt 208 are fixedly installed for relative transmission. At this time, the protruding part of the Λ-shaped roller belt 206 is embedded in the concave part of the V-shaped roller belt 208, forming a clamping structure similar to the engagement of gears, so that the copper wire can be tightly clamped between the outer side of the Λ-shaped roller belt 206 and the V-shaped inner part of the V-shaped roller belt 208. The two-way extrusion friction force is used to achieve stable biting and traction. At the same time, the electric push rod 201 pushes the Λ-shaped frame 202 through the piston rod to drive the threaded rod 203 and the traction block 205 to slide up and down in the traction groove 103, so as to adjust the depth of the Λ-shaped roller belt 206 pressing into the V-shaped roller belt 208, thereby changing the extrusion force on the copper wire, so that it can adapt to copper wires of different diameters or hardnesses. After the adjustment is completed, the threaded rod 206 can be locked by rotating the hand wheel 204 to contact the upper and lower surfaces of the N-shaped frame 102. 3 is raised and lowered to ensure stable pressure, and the convex shape of the Λ-shaped roller belt 206 is maintained by the Λ-shaped disk 214 on the outer surface of the first transmission column 211, and the top contact plate 215 between the second transmission columns 207 contacts the inner annular surface of the V-shaped roller belt 208 to prevent it from collapsing inward due to compression, ensuring that the two sets of roller belts always maintain a precise concave-convex interlocking state, so that the copper wire is covered by multi-angle pressure of the combination of Λ and V shapes during the pulling process, which not only corrects the straightness, but also eliminates complex deformations such as local bending and torsion, thereby achieving efficient and continuous straightening.

[0032] like Figure 7-Figure 8As shown, the traction rolling mechanism 3 includes an installation box 301 and two sets of bearing seats 311. The installation box 301 and the bearing seats 311 are fixedly installed on the upper surface of the second connecting box 101. The first connecting disk 302 and the second connecting disk 303 are rotatably installed at one end of the installation box 301. The other ends of the first connecting disk 302 and the second connecting disk 303 are rotated through the installation box 301 and the ends are fixedly installed with gears 304 and meshed with each other, so that the first connecting disk 302 and the second connecting disk 303 can also rotate relative to each other to achieve the biting and traction of the copper wire, and the gear 304 of the second connecting disk 303 is fixedly installed at one end of the third transmission disk 305. The outer surface of the third transmission disk 305 is also covered with a transmission belt, and the other end of the transmission belt is covered on the outer surface of one set of the second transmission disks 213. The copper wire bitten by the first connecting disk 302 and the second connecting disk 303 will be pulled into the rotating tube 310, and the rotating tube 310 is rotatably installed between the two sets of bearing seats 311.

[0034] The outer ends of the rotating tube 310 are connected to the expansion tube 312, and the inner wall of the expansion tube 312 is evenly distributed with four groups of sliding grooves 320 along the circumference. Three groups of C-shaped frames 315 are slidably mounted in each group of sliding grooves 320. The open ends of the C-shaped frames 315 are rotatably mounted with ball bearings 318 through bearings. The ball bearings 318 in the four groups of sliding grooves 320 together constitute a straightening channel for the copper wire to pass through. When the rotating tube 310 drives the expansion tube 312 to rotate, the outer circumferential surfaces of the ball bearings 318 roll in contact with the outer surface of the copper wire to form a 360° circumferential rolling structure. Guide blocks 319 are fixed to the two ends of the C-shaped frame 315. The guide blocks 319 and the guide grooves 308 provided at the two ends of the sliding grooves 320 form a sliding pair. The sliding stroke of the guide blocks 319 along the guide grooves 308 defines the radial movement trajectory of the C-shaped frame 315.

[0035] A connecting column 316 is fixedly installed in the sliding groove 320, and the connecting column 316 slides into the C-shaped frame 315. A rectangular spring 317 is sleeved on the outer surface of the connecting column 316, and the two ends of the rectangular spring 317 are respectively fixedly connected between the sliding groove 320 and the C-shaped frame 315.

[0036] Through the design of the first connecting disk 302, the second connecting disk 303, the gear 304, the third transmission disk 305, the fourth transmission disk 309, the rotating tube 310, the connecting block 313, the combing hole 314; the expansion tube 312, the U-shaped frame 315, the ball bearing 318, the connecting column 316 and the rectangular spring 317, during the process of the second reduction motor 210 driving the multiple groups of second transmission columns 207 to rotate, the second transmission columns 207 of one group can drive the third transmission disk 305 to rotate together through the transmission belt set on the outer surface of the second transmission disk 213 at the other end, and the third transmission disk 305 can drive one group of gears 304 to rotate, and the driven rotating gear 304 can mesh with the transmission gear 304 at the other end to rotate together.

The copper wire is straight and in the middle, reducing the friction with the tube wall, and then the copper wire can be inserted out from the gap between the ball bearings 318 again, and the ball bearing 318 is slidably installed in the sliding groove 320 opened in the expansion tube 312 through the U-shaped frame 315. Then, as the rotating tube 310 continues to rotate 360 ​​degrees, it can drive the ball bearing 318 to rotate with the contact friction with the copper wire, allowing it to perform all-round rolling and pressing on the outer surface of the copper wire. The connecting column 316 and the rectangular spring 317 in the sliding groove 320 form an elastic buffer structure. When there is a slight change in the diameter of the copper wire or the rotating tube 310 rotates and vibrates, the rectangular spring 317 can allow the U-shaped frame 315 to drive the ball bearing 318 to adaptively expand and contract, so that the ball bearing 3 18 can provide sufficient straightening pressure and prevent the surface of the copper wire from being damaged due to excessive pressure. Through this elastic contact and 360° dynamic rolling, the bending and deformation of the copper wire in all directions can be effectively corrected, and finally a finished copper wire with high precision and standard straightness is output from the device, meeting the strict quality requirements of various precision processing on wire materials. In addition, during the expansion and contraction of the U-shaped frame 315 in the sliding groove 320, the U-shaped frame 315 can slide stably in the sliding groove 320 through the cooperation of the guide block 319 and the guide groove 308, ensuring that the ball bearing 318 always keeps in contact with the copper wire during the rolling process, avoiding poor contact or offset, and also allowing the elastic structure composed of the connecting column 316 and the rectangular spring 317 toThe ball bearing 318 can adaptively fit copper wires of varying diameters, providing sufficient straightening pressure while preventing damage to the wire surface due to excessive pressure. Furthermore, the elastic buffer effectively absorbs vibrations during the rotation of the rotating tube 310, ensuring a smooth rolling process. Ultimately, efficient and high-precision 360° rolling straightening of the copper wire is achieved, producing finished products with excellent straightness and surface quality. The wire, after being rolled by the ball bearing 318, passes again through the tapered combing hole 314.

[0037] It also includes an intelligent control system that executes a dynamic roller pressure adaptive algorithm, and its target pressure P ad Determined by the following equation: in: P ad : adaptive target pressure (MPa); σ y : real-time yield strength of copper wire (MPa); k: material strain hardening coefficient (0.1~0.3); : Cumulative integral of the absolute value of the strain change rate (s -1 ); δ: curvature measured by laser micrometer (mm / m); L: reference length of straightening area (m); β: dynamic shape factor (3~8).

[0038] Among them, the strain change rate Solved by the following process: Where v is the real-time linear velocity of the encoder, v0 is the entry reference velocity, and Δt is the sampling interval (10ms).

[0039] The value of the shape factor β follows: Where D is the copper wire diameter (mm), and β is saturated at 5 when D ≥ 2 mm.

[0040] This equation uniformly models the material's yield strength, strain history, and geometric deformation, and the tanh function achieves precise control of small deformations (approximately linear when δ / L≤0.3) and pressure limiting of large deformations (saturation when δ / L>0.3).

[0043] This equation solves the long-standing problem of compensating for material hardening effects in the field of high-precision straightening through the cumulative effect of strain history and geometric-material decoupling design.

[0044] The detailed working steps of this equation are as follows: 1. Data acquisition phase (10ms cycle): The laser micrometer scans the surface of the copper wire at a frequency of 50kHz to calculate the bending per unit length δ The rotary encoder detects the copper wire transmission speed v and calculates the instantaneous strain ; Differential calculation of strain change rate dε / dt=(ε t -ε t-1 ) / Δt; The integrator accumulates the |dε / dt| value (recording the degree of work hardening); 2. Parameter matching stage: The material database retrieves the σ_y and k values ​​according to the copper wire model; The diameter sensor measures the D value and calculates β=5(1-e -D ); The reference length L is fixed to the physical length of the straightening zone; 3. Equation solving stage: Calculate the geometric deformation factor: tanh(β·δ / L); When δ / L≤0.3: Approximate linear relationship (precise control); When δ / L>0.3: the output is saturated to 1.0 (overload protection); Calculate the material strengthening factor: (1+k·∫|dε / dt|dt); Synthetic target pressure: P_ad=σ_y×strength factor×deformation factor; 4.Actuator action: The servo driver converts P_ad into displacement (proportional coefficient 0.014mm / MPa); The electric push rod adjusts the pressing depth of the Λ-shaped roller belt; The pressure sensor verifies the actual pressure value in real time; 5.Quality closed-loop feedback: After straightening, the copper wire passes through the laser micrometer again; The new δ value is fed back to the control system; When δ>threshold, the integral weight k is automatically increased; When ∫|dε / dt|dt>5, the speed reduction protection is triggered.

[0045] According to the above technical solution, the working steps of this solution are summarized and sorted out: when straightening the copper wire, the first reduction motor 209 and the second reduction motor 210 can be started to synchronously drive the first transmission column 211 and the second transmission column 207 to rotate relative to each other, and the relatively rotating first transmission column 211 and the second transmission column 207 can be synchronously driven to rotate through the first transmission disk 212 and the second transmission disk 213 fixedly installed at the other end, so that the multiple groups of first transmission columns 211 and the second transmission columns 207 can respectively drive the conveyor belt 216, between which the Λ-shaped roller belt 206 and the V-shaped roller belt 208 are fixedly installed for relative transmission. At this time, the protruding part of the Λ-shaped roller belt 206 is embedded in the concave part of the V-shaped roller belt 208, forming a clamping structure similar to the engagement of gears, so that the copper wire can be tightly clamped between the outer side of the Λ-shaped roller belt 206 and the V-shaped embedded groove of the V-shaped roller belt 208, and stable biting and traction are achieved through this two-way extrusion friction force; At the same time, the electric push rod 201 pushes the Λ-shaped frame 202 through the piston rod to drive the threaded rod 203 and the traction block 205 to slide up and down in the traction groove 103, so as to adjust the depth of the Λ-shaped roller belt 206 pressing into the V-shaped roller belt 208, thereby changing the squeezing force on the copper wire so that it can adapt to copper wires of different diameters or hardnesses. After the adjustment is completed, the threaded rod 203 can be locked by rotating the hand wheel 204 to contact the upper and lower surfaces of the N-shaped frame 102, thereby ensuring stable pressure and The Λ-shaped disc 214 on the outer surface of the first transmission column 211 maintains the convex shape of the Λ-shaped roller belt 206, and the top contact plate 215 between the second transmission columns 207 contacts the inner annular surface of the V-shaped roller belt 208 to prevent it from collapsing inward due to compression, ensuring that the two sets of roller belts always maintain a precise concave-convex interlocking state. The copper wire is subjected to multi-angle pressure coverage of the Λ-shaped and V-shaped combination during the pulling process, which not only corrects the straightness but also eliminates complex deformations such as local bending and torsion, achieving efficient and continuous straightening. In the process of the second reduction motor 210 driving multiple groups of second transmission columns 207 to rotate, one group of second transmission columns 207 can drive the third transmission disk 305 to rotate together through the transmission belt set on the outer surface of the second transmission disk 213 at the other end, and the third transmission disk 305 can drive one group of gears 304 to rotate, and the driven rotating gear 304 can mesh with the transmission gear 304 at the other end to rotate relatively, so that the two groups of gears 304 can drive the first connecting disk 302 and the second connecting disk 303 to rotate relatively together, and the relatively rotating first connecting disk 303 can rotate relatively together. The clamping force formed by the receiving disc 302 and the second connecting disc 303 can bite into and stably pull the copper wire that has been preliminarily processed, and the pulled copper wire can enter the rotating tube 310 that is rotatably installed between the two sets of bearing seats 311. In this process, the third reduction motor 306 can be started together to drive the rotating tube 310 to rotate 360 ​​degrees continuously through the fifth transmission disc 307, the transmission belt and the fourth transmission disc 309. The tapered combing hole 314 of the connecting block 313 in the rotating tube 310 can guide and reshape the copper wire passing through it, ensuring that it is centered and straight in the rotating tube 310, reducing friction with the tube wall. Then the copper wire can be inserted from the gap between the ball bearings 318 again, and the ball bearings 318 are slidably installed in the sliding groove 320 provided in the expansion tube 312 through the U-shaped frame 315. Then, as the rotating tube 310 continues to rotate 360 ​​degrees, the ball bearings 318 can be driven to rotate with the contact friction with the copper wire, so that the ball bearings 318 can be rolled on the outer surface of the copper wire in all directions. The connecting column 316 and the rectangular spring 317 in the sliding groove 320 form an elastic buffer structure. When there are slight changes in the wire diameter or when the rotating tube 310 vibrates during rotation, the rectangular spring 317 allows the U-shaped frame 315 to drive the ball bearing 318 to adaptively expand and contract, so that the ball bearing 318 can provide sufficient straightening pressure while preventing damage to the copper wire surface due to excessive pressure. Through this elastic contact and 360° dynamic rolling, the bending and deformation of the copper wire in all directions can be effectively corrected. The pressure from the ball bearing 318 is then discharged again through the tapered combing hole 314, producing high-precision straightened copper wire.

[0046] In summary: During the straightening process of the copper wire by the continuous straightening device for copper wire production, continuous pressure can be applied to the copper wire by multi-angle pressure covering. In this process, the pressure in multiple directions works together to accurately correct the straightness of the copper wire, effectively eliminate the complex deformation problems such as bending and twisting of the copper wire, and preliminarily realize the straightening of the copper wire. The copper wire that has completed the preliminary straightening will be bitten by the continuous straightening mechanism 2 and a 360° rolling straightening operation will be performed on the outer surface of the copper wire. This all-round rolling treatment can perform secondary fine correction on the copper wire, so that it can produce high-precision and high-quality straightened copper wire.
