Description

Technical Field

[0001] The invention relates to the technical field of metal wire processing, in particular to a metal wire surface polishing device. Background Art

[0002] After being drawn and formed, metal wires (such as copper wire, aluminum wire, iron wire, etc.) need to be polished. The commonly used process is to use a rotating wheel with a bristle covered on the curved surface for polishing. During the operation, the metal wire is in a continuous moving state. Figure 9 As shown, a single wheel can only cover a small section of the wire arc. In order to fully grind the entire circumference of the wire, multiple sets of wheels must be arranged around the wire axis.

[0003] The existing wire grinding technology has the following shortcomings: 1. The bristles are squeezed by the metal wire to form an arc-shaped depression. The pressure exerted on the wire surface by the edge and the center of the depression is uneven, resulting in poor polishing effect at the edge. Furthermore, the uniformity of the overall polishing of the metal wire is also poor. 2. The wheels are distributed circumferentially around the wire, and their rotation axes point in different directions. A complex transmission system must be designed to ensure that multiple wheels rotate synchronously and at the same speed, resulting in a bloated device structure. Summary of the Invention

[0004] The purpose of the present invention is to provide a metal wire surface polishing device, which solves the problem that the bristles of the rotating wheel of the existing polishing device exert uneven pressure on the arc surface of the metal wire, resulting in poor uniformity in the overall polishing of the metal wire, and the circumferential distribution of multiple groups of rotating wheels requires a complex transmission system, resulting in a bloated device structure.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a metal wire surface polishing device, comprising: A workbench is provided with a brush wheel 1 and a brush wheel 2 for grinding the upper and lower surfaces of the moving metal wire, and a drive system for driving the brush wheel 1 and the brush wheel 2 to rotate is provided on one side of the workbench; The wire control mechanism is provided in two groups and is assembled on both sides of the workbench. The wire control mechanism includes at least three positioning wheels arranged circumferentially, and the plurality of positioning wheels are used to centrally clamp the traveling metal wire; the wire control mechanism also includes a rotating structure assembled on one side of the plurality of positioning wheels; The coordination mechanism is used to control the synchronous operation of two sets of line control mechanisms; With the cooperation of the rotating structure and the coordinated mechanism, the two groups of multiple positioning wheels rotate back and forth periodically with the metal wire as the axis, so that the metal wire clamped between the two wire control mechanisms rotates back and forth with the wheel mounting frame during movement.

[0006] As a further description of the above technical solution: the rotating structure includes a wheel mounting frame, which circumferentially assembles multiple positioning wheels so that the multiple positioning wheels are distributed around the arc surface of the metal wire. Both sides of the wheel mounting frame are fixedly connected with a rotating seat, and the outer surface of the rotating seat is rotatably provided with a mounting seat, and the mounting seat is fixedly assembled on the table top of the workbench.

[0007] As a further description of the above technical solution: a gear ring is fixed on the surface of the rotating seat.

[0008] As a further description of the above technical solution: the cooperative mechanism includes a rack meshingly arranged below the gear ring, a push rod is fixedly connected to one side of the rack, and a slide rail is arranged on the lower side of the rack.

[0009] As a further description of the above technical solution: the cooperative mechanism also includes a motor 1, the output end of the motor 1 is connected to a drive shaft, the surface of the drive shaft is fixedly connected to an eccentric wheel, the outer surface of the eccentric wheel is rotatably sleeved with a rotating ring, and the arc surface of the rotating ring is rotatably connected to one end of the push rod.

[0010] As a further description of the above technical solution: one end of the rotating shaft of the positioning wheel is connected to a friction wheel, one side of the friction wheel is provided with a friction block in friction contact with it, and one side of the friction block is provided with a pushing unit. The pushing unit controls the pressure generated by the contact between the friction block and the friction wheel by pushing the friction block, thereby increasing the resistance when the positioning wheel rotates.

[0011] As a further description of the above technical solution: the number of the positioning wheels is an even number, and the multiple positioning wheels are evenly arranged circumferentially with the metal wire as the axis.

[0012] As a further description of the above technical solution: the friction wheel is arranged in a truncated cone or a conical shape, the outer inclined surfaces of two adjacent friction wheels are parallel, and the pushing unit simultaneously pushes the two friction blocks from a direction perpendicular to the outer inclined surfaces of the two friction wheels to frictionally contact the corresponding friction wheel inclined surfaces.

[0013] As a further description of the above technical solution: the two sides of the workbench are respectively provided with: a wire pay-out table for placing the metal wire roll to be polished, and a winding mechanism for winding the polished metal wire. A preset distance is set between the winding mechanism, the wire pay-out table and the adjacent side of the workbench.

[0014] As a further description of the above technical solution: one side of the rotating seat rotates and protrudes to the outside of the mounting seat, and an assembly plate is provided on this side, and one side of the assembly plate is used for assembling the auxiliary device.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Through the coordination of the rotating structure and the coordinated mechanism, the two wire-control mechanisms perform periodic reciprocating rotation around the wire. The wire, clamped between the two sets of positioning wheels, reciprocates with the positioning wheels as it moves. Brushes 1 and 2 polish the moving wire, evenly distributing polishing pressure across the wire surface and significantly improving polishing accuracy. Because the wire actively reciprocates, the parallel rotation axes of brushes 1 and 2 simplify the drive system, resulting in a compact structure and reduced failure rates.

[0016] 2. By controlling the rotational resistance of the positioning wheel through the damping structure, the tension of the metal wire in the moving state can be adjusted so that it contacts the brush wheel 1 and the brush wheel 2 according to the preset state, thereby ensuring the effective polishing effect of the brush wheel 1 and the brush wheel 2 on the metal wire.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0021] Figure 9 1 is a cross-sectional diagram showing an arc-shaped depression on the bristles 111 when the bristles 111 on the surface of the brush wheel 11 come into contact with the metal wire; Combine Figures 1 to 8 , a metal wire surface polishing device, comprising: The workbench 10 is equipped with a brush wheel 11 and a brush wheel 2 12 for grinding the upper and lower surfaces of the moving metal wire, and the two have the same structure. A drive system 13 is provided on one side of the workbench 10 for driving the brush wheels 11 and 12 to rotate. The rotation axes of the brush wheels 11 and 12 are arranged horizontally and in parallel. The drive system 13 adopts a traditional drive structure, such as a gear drive, a belt drive or a sprocket drive, to drive the parallel rotation axes of the brush wheels 11 and 12 to rotate synchronously and at the same speed. The driving source of the drive structure is a motor, specifically comprising: the motor output shaft is equipped with two coaxially arranged sprocket wheels 1, and one end of the rotation axis of the brush wheels 11 and 12 is equipped with a sprocket 2, and the sprocket 1 and sprocket 2 are connected by a chain.

[0022] like Figure 1 、 Figure 2 As shown, two groups of wire control mechanisms 20 are provided, which are respectively assembled on both sides of the workbench 10 , and the metal wire passes through the centers of the two wire control mechanisms 20 , and the brush wheel 11 and the brush wheel 2 12 are arranged between the two wire control mechanisms 20 .

[0023] The wire control mechanism 20 includes at least three positioning wheels 23, arranged circumferentially. As the wire travels between the wheels 23, they adaptively rotate to clamp the wire in its center. The edges of the wheels 23, which hold the wire, are preferably plastic rings. These rings are made of the same elastic, wear-resistant, non-slip, and impact-resistant clamping pads used in mechanical grippers and automated equipment. The wheels 23 clamp the wire through their own deformation.

[0024] The wire control mechanism 20 also includes a rotating structure mounted on one side of multiple wheel mounting frames 22. These rotating structures include the wheel mounting frames 22, which circumferentially mount multiple positioning wheels 23, distributing them around the curved surface of the wire. Rotating bases 21 are fixedly connected to each side of the wheel mounting frames 22. Mounting bases 25 are rotatably mounted on the outer surface of the rotating bases 21, which are fixedly mounted to the workbench 10. When the rotating bases 21 rotate on the mounting bases 25, they drive the positioning wheels 23, and the wire they hold, to rotate about their axis.

[0025] The coordination mechanism 30 is used to control the synchronous operation of the two line control mechanisms 20. A gear ring 24 is fixedly mounted on the surface of the rotating base 21. The coordination mechanism 30 includes a rack 35 meshingly disposed below the gear ring 24. A push rod 34 is fixedly connected to one side of the rack 35. A slide rail is provided below the rack 35. The rack 35 slides back and forth on the slide rail and, through the meshing gear ring 24, drives the rotating base 21 to reciprocate.

[0026] The cooperative mechanism 30 also includes a motor 36, which is fixedly mounted on the upper side of the workbench 10. The output end of the motor 36 is connected to a drive shaft 31, which is rotatably mounted on the upper side of the workbench 10 via a bearing seat. An eccentric wheel 32 is fixedly connected to the surface of the drive shaft 31, and the drive shaft 31 and the eccentric wheel 32 are eccentrically connected. A swivel 33 is rotatably mounted on the outer surface of the eccentric wheel 32, and the curved surface of the swivel 33 is rotatably connected to one end of a push rod 34. When the drive shaft 31 rotates, the eccentric wheel 32 rotates as a whole with the drive shaft 31. Due to the eccentricity between the geometric center of the eccentric wheel 32 and the center of the drive shaft 31, the eccentric wheel 32 does not rotate around its own center, but instead performs a circular motion around the center of the drive shaft 31. At this time, the swivel 33, which is rotatably connected to the outer side of the eccentric wheel 32, is constrained by the push rod 34, forming a periodically changing trajectory. Specifically, the position where the swivel 33 is connected to the push rod 34 will reciprocate closer to or farther away from the drive shaft 31, thereby producing the effect of reciprocating horizontal movement. Then, the reciprocating push rod 34 drives the rack 35 to rotate back and forth.

[0027] Furthermore, with the cooperation of the rotating structure and the coordination mechanism 30, the two sets of multiple positioning wheels 23 periodically reciprocate around the metal wire as the axis. The metal wire, clamped between the two sets of positioning wheels 23, reciprocates with the positioning wheels 23 during movement. Subsequently, the rotating brush wheels 11 and 12 polish the moving, reciprocating metal wire, ensuring that the pressure applied by the brush wheels 11 and 12 to polish the metal wire evenly covers the surface of the metal wire, thereby improving the polishing accuracy of the metal wire surface.

[0028] Combine Figure 6 and Figure 7One end of the rotating shaft 26 of the positioning wheel 23 is connected to a friction wheel 27. A friction block 28 is provided on one side of the friction wheel 27 for frictional contact with the friction wheel 27. A pusher unit 29 is provided on the other side of the friction block 28, preferably a servo cylinder. Pusher unit 29 controls the pressure generated by the contact between the friction block 28 and the friction wheel 27 by pushing on the friction block 28, thereby increasing the resistance to the rotation of the positioning wheel 23. The damping structure formed by the friction wheel 27, friction block 28, and pusher unit 29 adjusts the rotational resistance of the positioning wheel 23, thereby adjusting the tension of the metal wire during polishing of brush wheels 11 and 12.

[0029] Specifically, the damping structure is disposed on the wire control mechanism 20 at the initial position along the wire's travel path. As the wire travels between brush wheel 1 11 and brush wheel 2 12, the two wheels rotate, and the centrifugal force of the bristles 111 on their surfaces pushes the wire to one side. This not only affects the contact area between the bristles 111 and the wire, but also reduces the contact pressure, thereby affecting the polishing effect. By controlling the rotational resistance of the positioning wheel 23 through the damping structure, the tension of the wire during travel can be adjusted, causing it to contact brush wheel 1 11 and brush wheel 2 12 according to a preset state, thereby ensuring that brush wheel 1 11 and brush wheel 2 12 effectively polish the wire.

[0030] The number of positioning wheels 23 is even, and they are evenly arranged circumferentially around the wire. The friction wheels 27 are truncated cone-shaped or conical, with the outer inclined surfaces of two adjacent friction wheels 27 parallel to each other. The pushing unit 29 simultaneously pushes the two friction blocks 28 perpendicular to the outer inclined surfaces of the friction wheels 27, bringing them into frictional contact with the corresponding inclined surfaces of the friction wheels 27.

[0031] Combine Figure 7 Taking the example of four positioning wheels 23, the above design only requires two friction blocks 28 to achieve the same damping effect as when four positioning wheels 23 are used alone. Therefore, the number of push units 29 required is only half the number of positioning wheels 23, significantly saving investment costs.

[0032] Combine Figure 1 A winding mechanism 40 and a pay-off platform 50 are provided on both sides of the workbench 10. The pay-off platform 50 is used to place the wire roll to be polished, while the winding mechanism 40 is used to reel in the polished wire. Specifically, the winding mechanism 40 includes a reel, which is controlled and rotated by a drive structure on one side, and the drive structure preferably adopts a servo motor. The servo motor drives the reel to rotate, thereby continuously reeling in the wire and ensuring that the wire can pass through the workbench 10 at a uniform speed.

[0033] The winding mechanism 40 and the pay-off platform 50 are both spaced apart from the adjacent side of the workbench 10 by a preset distance. When the two sets of wire-control mechanisms 20 reciprocate the metal wire held between them, the wire between the wire-control mechanism 20 and the pay-off platform 50, as well as the wire between the other wire-control mechanism 20 and the winding mechanism 40, will experience reciprocating twisting. To reduce damage to the wire caused by this twisting, the spacing between the two wire-control mechanisms 20 and the corresponding winding mechanism 40 and pay-off platform 50 is controlled, increasing the reserved length of the wire between them. This prevents metal fatigue caused by twisting due to an excessively short reserved length.

[0034] Combine Figure 8 As shown, one side of the rotating base 21 rotates and protrudes outward from the mounting base 25. This side is provided with an assembly plate 211. One side of the assembly plate 211 is used to mount auxiliary devices. Auxiliary devices include a wire straightener, which is mounted on the side of the rotating base 21 at the beginning of the wire's travel path, or a wire surface flaw detector, which is mounted on the side of the rotating base 21 at the end of the wire's travel path. The auxiliary devices reciprocate synchronously with the rotating base 21, ensuring that the reciprocating auxiliary devices and the reciprocating wire are in near-synchronous rotation, facilitating wire straightening or testing.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
