Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and specifically to an environmentally friendly surface treatment device for copper wire drawing. Background Technology

[0002] In the production of wires and cables, copper wires need to have their surface oxide layer, oil, and impurities removed before the drawing process to ensure the conductivity and surface quality of the finished wire. Currently, mechanical-physical rust removal devices are widely used due to their environmentally friendly and pollution-free characteristics.

[0003] Most existing devices, such as rotary brush heads, only drive the abrasive media to rotate in a single direction around the copper wire. Since the copper wire travels in a straight axial direction during processing, this single rotational motion results in the abrasive media leaving regular, continuous spiral scratches on the wire surface. These directional marks may evolve into cracks or surface defects in subsequent drawing processes, severely affecting the wire's fatigue strength and surface finish. Due to structural limitations, it is difficult to simulate the axial back-and-forth rubbing motion used by humans when cleaning objects, resulting in a lack of randomness in the abrasive path and an inability to achieve comprehensive deep polishing. Therefore, we propose an environmentally friendly surface treatment device for copper wire before drawing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an environmentally friendly surface treatment device for copper wire drawing, which overcomes the deficiencies of existing technologies, has a reasonable design and compact structure, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An environmentally friendly surface treatment device for copper wire drawing includes a housing, a planetary gear mechanism and a processing component connected thereto within the housing, the processing component including a first cylinder and a second cylinder; the planetary gear mechanism drives the first cylinder and the second cylinder to generate a speed difference, and under the drive of the speed difference, the second cylinder rotates around the axis of the housing while reciprocating linear motion along its axis.

[0007] Preferably, the two ends inside the housing are provided with a fixed internal gear ring and a rotatable internal gear ring, and there is an axial gap between the fixed internal gear ring and the rotatable internal gear ring.

[0008] Preferably, a connecting plate is provided circumferentially between the fixed internal gear ring and the rotating internal gear ring, and turntables are connected to both ends of the connecting plate. The two turntables are respectively rotated and engaged with the fixed internal gear ring and the rotating internal gear ring.

[0009] Preferably, the planetary gear mechanism includes a sun gear arranged at the center and a first planet gear and a second planet gear arranged circumferentially; the first planet gear is mounted on one of the turntables via a rotating shaft and meshes with both the sun gear and the fixed internal gear ring.

[0010] Preferably, the first cylinder is fixed to the end face of the sun gear; the second cylinder is disposed in the internal space formed by the connecting plate, and the outer wall of the second cylinder is slidably engaged with the inner wall of the connecting plate.

[0011] Preferably, the first cylinder has an inlet rod on its end face and the second cylinder has a groove on its end face, and a wave rail formed by multiple arc-shaped connections is provided in the groove; the inlet rod and the wave rail are engaged to drive the second cylinder to perform axial reciprocating motion under the speed difference.

[0012] Preferably, the inner wall of the connecting plate is provided with a groove extending along its length, and the outer wall of the second cylinder is provided with a slide rail that slides in cooperation with the groove.

[0013] Preferably, a spring is provided at the end of the second cylinder opposite to the first cylinder. The spring is used to provide axial restoring force to the second cylinder to maintain close contact between the wave rail and the guide rod.

[0014] Preferably, the first planetary gear and the second planetary gear are synchronously connected by a connecting shaft. The middle part of the connecting shaft is provided with a bent part that protrudes outward from its rotation axis. The bent part generates an excitation force when it rotates with the connecting shaft.

[0015] Preferably, the interiors of both the first and second cylinders are filled with a flexible abrasive material for coating the copper wires to be treated.

[0016] This invention provides an environmentally friendly surface treatment device for copper wire before drawing. It has the following beneficial effects:

[0017] 1. Utilizing the differential speed principle of planetary gear systems, the inner second cylinder rotates along with the connecting plate while simultaneously generating a high-frequency axial reciprocating motion through the cooperation of the wave rail and the guide rod. This composite motion trajectory of circumferential rotation and axial reciprocating motion simulates the action of repeated wiping from multiple angles by human hands, effectively disrupting the grinding path, avoiding the generation of directional patterns, and significantly improving the surface finish of the copper wire before drawing.

[0018] 2. The connecting shaft is equipped with a bend, which uses the high-speed rotation of the planetary gear system to make it a non-contact eccentric vibration source. On the one hand, the generated high-frequency vibration can loosen the stubborn oxide layer on the surface of the copper wire. On the other hand, the vibration force can effectively overcome the static friction force when the second cylinder slides axially, preventing the slide rail from jamming or seizing, ensuring the smoothness and reliability of mechanical movement. Moreover, due to the non-contact design, it also avoids additional mechanical collision noise and wear.

[0019] 3. By utilizing the rotational speed difference between the first and second cylinders, the flexible material filled between them is subjected to a continuous alternating state of compression and relaxation. Combined with the high-frequency micro-vibration caused by the bending of the connecting shaft, the device can quickly shake off the waste debris adhering deep within the gaps of the flexible material.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this invention, not all of it. All other works obtained by those skilled in the art based on this invention without inventive effort are within the scope of protection of this invention.

[0029] See attached document Figures 1-7 An environmentally friendly surface treatment device for copper wire before drawing includes a housing 1. The housing 1 is supported and fixed by a support leg at the bottom, and the copper wire to be treated is arranged to pass through the housing 1 along its axis.

[0030] Inside the housing 1, at both ends, there is a fixed internal gear ring 2 and a rotating internal gear ring 3, respectively. The fixed internal gear ring 2 is fixed to the housing 1 and cannot rotate; the rotating internal gear ring 3 is rotatably mounted inside the housing 1 via bearings. A certain axial distance is maintained between the fixed internal gear ring 2 and the rotating internal gear ring 3.

[0031] A connecting plate 4, i.e., a planetary carrier structure, is circumferentially arranged between the fixed internal gear ring 2 and the rotating internal gear ring 3. Turntables 41 are fixedly connected to both ends of the connecting plate 4. The outer walls of the two turntables 41 are respectively rotated and engaged with the inner holes of the fixed internal gear ring 2 and the rotating internal gear ring 3 through bearings, so that the overall structure formed by the connecting plate 4 and the turntables 41 can rotate independently within the housing 1.

[0032] The power transmission system mainly includes an external drive mechanism, a drive gear 22, a shaft 21, a sun gear 23, a first planetary gear 24, and a second planetary gear 31.

[0033] Input end: One end of the shaft 21 extends to the outside of the housing 1 and is connected to a drive gear 22. The drive gear 22 meshes with an external drive mechanism to receive rotational power, such as a gear fixed to the output end of a motor, which meshes with the drive gear 22 to form a drive. The other end of the shaft 21 extends into the housing and a sun gear 23 located at the center is fixedly connected to its shaft surface.

[0034] Planetary transmission: On a turntable 41 near the fixed internal gear ring 2, multiple first planetary gears 24 are circumferentially mounted via a rotating shaft; on a turntable 41 near the rotating internal gear ring 3, multiple second planetary gears 31 are circumferentially mounted via a rotating shaft. The first planetary gears 24 mesh with both the sun gear 23 and the fixed internal gear ring 2. The sun gear 23 is fixedly connected to a shaft 21, which extends through the center of the turntable 41 and outwards from the housing 1 via bearings to receive power. When the shaft 21 drives the sun gear 23 to rotate, the meshing of the first planetary gears 24 with the fixed internal gear ring 2 forces the turntable 41 to rotate at a low speed following the sun gear 23.

[0035] Linkage structure: The first planetary gear 24 and the corresponding second planetary gear 31 are coaxially connected by a connecting shaft 6, so that the planetary gear systems on both sides move synchronously, thereby driving the two turntables 41 to rotate synchronously.

[0036] Within the space between the fixed internal gear ring 2 and the rotating internal gear ring 3, i.e. the internal space of the connecting plate 4, a first cylinder 55 and a second cylinder 5 are coaxially arranged.

[0037] The first cylinder 55 is fixedly connected to the end face of the sun gear 23 and rotates with the sun gear 23 at the same speed and direction. A pair of guide rods 56 are also provided on the end face of the first cylinder 55.

[0038] The second cylinder 5 is located inside the connecting plate 4, and a slide rail 51 is connected to the axial side of its outer wall. The slide rail 51 slides in conjunction with the plate groove 42 opened in the inner wall of the connecting plate 4 along the length direction. This fit restricts the circumferential rotation of the second cylinder 5 relative to the connecting plate 4, requiring it to rotate with the connecting plate 4, but allows it to slide axially.

[0039] On the end face of the second cylinder 5 near the first cylinder 55, a groove 53 is formed circumferentially along its axial direction. A wave rail 54 formed by multiple arc-shaped joints is provided in the groove 53. The guide rod 56 on the first cylinder 55 extends into the wave rail 54 and abuts against it.

[0040] Spring 52 is located at the other end of the second cylinder 5. One end of spring 52 is supported by a plane bearing against the end face of turntable 41, and the other end is supported by a plane bearing against the end face of the second cylinder 5. It is used to provide axial restoring force and maintain close contact between guide rod 56 and wave rail 54.

[0041] Both the second cylinder 5 and the first cylinder 55 are filled with flexible abrasive material, through which copper wires run. The flexible abrasive material can be copper wire or brass wire.

[0042] Working principle: When the external drive mechanism drives the drive gear 22 to rotate, the shaft 21 drives the sun gear 23 and the first cylinder 55 to rotate at high speed, with a speed of V1;

[0043] The sun gear 23 drives the first planet gear 24 to rotate. Since the first planet gear 24 meshes with the non-rotatable fixed internal gear ring 2, it is forced to revolve along the inner wall of the fixed internal gear ring 2. This will cause the connecting plate 4 and the second cylinder 5 to rotate at a relatively low speed, with a rotational speed of V2.

[0044] At this moment, the first cylinder 55 rotates with V1, and the second cylinder 5 rotates with V2. Since V1 is not equal to V2, relative rotation occurs between the two.

[0045] This relative rotation causes the guide rod 56, fixed on the first cylinder 55, to slide relative to the wave track 54 of the second cylinder 5. The undulation of the wave track 54 forces the second cylinder 5 to make axial reciprocating linear motion along the plate groove 42 while rotating, and the spring 52 plays a buffering and rebounding role in this process.

[0046] The second cylinder 5 not only rotates with the connecting plate 4, but also undergoes high-frequency axial reciprocating vibration under the action of the guide rod 56 and the wave rail 54. This combined trajectory of rotation and axial rubbing simulates the action of manual "wiping back and forth", which can effectively disrupt the grinding path, prevent the formation of directional patterns on the surface of the copper wire, and significantly improve the surface finish.

[0047] The speed difference between the first cylinder 55 and the second cylinder 5 causes the flexible material inside to undergo continuous compression and relaxation. Combined with high-frequency axial vibration, this effectively shakes off impurities such as oxide scale and copper powder, preventing clogging of the pores in the flexible material, extending the service life of the consumables, and maintaining cleaning efficiency for extended periods of operation.

[0048] Copper wires often have internal stress before being drawn. This device, through the floating support of a plane bearing and spring 52, gives the grinding assembly a certain degree of "flexibility," enabling it to adapt to the slight radial runout of the copper wire and avoid wire breakage caused by rigid collisions. It is particularly suitable for high-speed production lines.

[0049] In the second embodiment, the only difference from the above scheme is that the middle part of the connecting shaft 6 is integrally formed with a bent portion. This bent portion protrudes in the direction away from the rotation axis of the connecting shaft 6, forming an eccentric mass block structure. The bending radius of the bent portion is less than the minimum distance from the axis of the connecting shaft 6 to the outer wall of the second cylinder 5, so that the bent portion remains in a suspended state without contact with the second cylinder 5 and other components during the high-speed rotation of the connecting shaft 6. When the device is running, the drive mechanism drives the first planetary gear 24 to rotate at high speed through the sun gear 23. Since the connecting shaft 6 and the first planetary gear 24 rotate synchronously, the bent portion on it then performs a high-speed eccentric rotation. Although it does not directly strike the second cylinder 5, it will be transmitted to the turntable 41 and the entire connecting plate 4 assembly through the connecting shaft 6, forcing the second cylinder 5 supported inside the connecting plate 4 and the flexible material filled with it to generate high-frequency micro-amplitude vibrations, effectively destroying the adhesion of the oxide layer on the surface of the copper wire. Combined with the macroscopic rotation and axial reciprocating motion, it can more thoroughly remove dirt in the micro-pits and significantly improve the surface finish.
