Description

Technical Field

[0001] This invention relates to the technical field of electroplating equipment, and in particular to a continuous copper plating equipment for processing hose steel wire. Background Technology

[0002] In rubber products such as high-pressure hoses and tires, the steel wire of the hose serves as a key reinforcing skeleton material, and its performance directly affects the strength, pressure resistance, and service life of the product. In order to achieve a firm bond between the steel wire and the rubber matrix, copper plating must be applied to its surface. The copper plating layer not only provides an excellent chemical bonding interface, but also effectively prevents steel wire corrosion and significantly improves the composite performance of rubber and metal.

[0003] Currently, the most commonly used copper electroplating process in the industry is the intermittent electroplating mode using a single steel wire. Specifically, a single steel wire is passed vertically or horizontally through the electroplating tank at a slow linear speed. Pre-plating, main plating, and post-treatment processes are completed in the tank. To ensure that the surface of the steel wire obtains a sufficiently thick and dense copper plating layer, it is necessary to ensure that it has sufficient residence time in the electroplating solution. Therefore, the copper plating process using steel wire is slow and has low work efficiency. At the same time, in order to extend the travel path of the steel wire in the tank, the electroplating tank is relatively long, resulting in a large space occupation, large amount of electroplating solution consumption, and large amount of electrical energy consumption. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a continuous copper plating treatment device for processing hose steel wire, the specific technical solution of which is as follows: The present invention provides a continuous copper plating processing device for processing hose steel wire, comprising an electroplating tank, a plurality of rollers vertically located within the electroplating tank, and a plurality of partitions disposed on the rollers along the axial direction of the rollers. The plurality of rollers are arranged in a ring on a horizontal plane, and the plurality of partitions on the rollers divide the outer wall of the rollers into multiple conductor zones. The conductor zones on adjacent rollers are staggered in the vertical direction. The steel wire is spirally wound around the plurality of rollers through the conductor zones on the rollers, and the rollers are rotatable. The electroplating barrel is equipped with several conveyor wheels to guide and transport the steel wire.

[0005] Furthermore, the processing equipment also includes a turntable, on which a plurality of the rollers are disposed, and the turntable drives the plurality of rollers to rotate.

[0006] Furthermore, the turntable is provided with a plurality of sliders that slide along the radial direction of the turntable, and the roller is rotatably mounted on the sliders; A support frame is provided on the electroplating barrel, and a core column is provided on the support frame. The core column passes through the turntable and extends into the space between several rollers. The turntable is slidably disposed on the core column, and the turntable and the core column are connected by a spring. A plurality of connecting rings are rotatably mounted on the core column, and the connecting rings are rotatably connected to each of the winding rollers via inclined pull arms.

[0007] Furthermore, a conical disc and a conical wheel are respectively provided on the core column and each of the winding rollers. The conical wheel is slidably disposed on the winding roller. The conical wheel is connected to the winding roller by a spring. The core column and the winding roller are driven by the conical disc and the conical wheel.

[0008] Furthermore, a side push ring is provided inside the electroplating barrel, which can reciprocate in the vertical direction and rotate synchronously with the turntable. Several connecting arms are provided inside the side push ring, and each connecting arm is provided with a rolling group. The rolling group is corresponding to the roller, and the rolling group consists of two rolling columns used to lock the roller.

[0009] Furthermore, two sliding columns are arranged opposite each other on the side push ring, and an annular groove is opened on the inner wall of the electroplating barrel. The annular groove includes two groove groups arranged corresponding to the two sliding columns. The groove group consists of an arc groove one, an arc groove two, and a transition groove. The arc groove one and the arc groove two are staggered in the vertical direction, and the arc groove one and the arc groove two are both coaxially arranged with the turntable.

[0010] Furthermore, the connecting arm is a telescopic rod, and the rolling assembly is movably arranged along the radial direction of the side push ring via the telescopic rod. The rolling assembly and the side push ring are connected by a spring.

[0011] Furthermore, a transmission ring and a transmission wheel are provided on the turntable for mutual transmission connection. The transmission wheel is provided with a retaining edge for locking the transmission ring. A drive motor is provided on the support frame. The output end of the drive motor is connected to the transmission wheel through a transmission shaft. The transmission wheel and the support frame are connected by a spring triple connection.

[0012] The beneficial effects of this invention are as follows: By spirally winding and conveying the steel wire within the electroplating tank, the movement path of the wire can be extended, thereby increasing its residence time and facilitating thorough copper plating. This reduces the volume and space occupied by the electroplating tank, lowers the consumption of electroplating solution and electricity, and simultaneously increases the wire conveying speed, thus improving work efficiency. Furthermore, this movement pattern allows the wire to contact different parts of the electroplating solution within the tank, improving plating uniformity and ultimately enhancing plating quality.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 8 As shown, a continuous copper plating equipment for processing hose steel wire according to the present invention includes an electroplating tank 1, a plurality of rollers 2 vertically located inside the electroplating tank 1, and a plurality of partitions 3 arranged on the rollers 2 along the axial direction of the rollers 2. The plurality of rollers 2 are arranged in a ring on the horizontal plane. The plurality of partitions 3 on the rollers 2 divide the outer wall of the rollers 2 into a plurality of wire guide areas. The wire guide areas on adjacent rollers 2 are staggered in the vertical direction. The steel wire 5 is spirally wound on the plurality of rollers 2 through the wire guide areas on the rollers 2, and the rollers 2 are arranged to rotate. The electroplating tank 1 is equipped with several conveyor wheels 4 for guiding and conveying the steel wire 5.

[0019] In this invention, the electroplating tank 1 stores electroplating solution, and a copper electrode plate 6 is inserted into the electroplating solution. A conveyor wheel 4 on the electroplating tank 1 and the copper electrode plate 6 are both connected to an external power source, thereby enabling the conveyor wheel 4 to transfer electrical energy to the steel wire 5, allowing the steel wire 5 to undergo normal electroplating treatment in the electroplating solution. The steel wire 5 is wound around several rollers 2 arranged in a ring, so that the shape of the steel wire 5 in the electroplating tank 1 is spiral, which facilitates the simultaneous storage of a large number of steel wires 5 in the electroplating tank 1, and the spiral steel wires 5 do not block each other, ensuring that every part of the outer wall of the steel wire 5 can contact the electroplating solution in the electroplating tank 1. The arrangement of several partitions 3 dividing the outer wall of the rollers 2 into multiple wire guide areas can conveniently confine the steel wire 5 between two adjacent partitions 3, and the staggered arrangement of the wire guide areas on two adjacent rollers 2 can make the rollers 2 convey the steel wire 5 in a spiral direction when the rollers 2 rotate, thereby realizing the continuous electroplating function of the steel wire 5.

[0020] like Figure 2As shown, the input and output ends of the steel wires 5 on several rollers 2 can be located above the electroplating barrel 1 and inside the lower side of the electroplating barrel 1, respectively. Several conveying wheels 4 set on the electroplating barrel 1 can guide the steel wires 5, so that the steel wires 5 are conveyed unidirectionally and continuously.

[0021] In use, a conveyor wheel 4 and a copper electrode plate 6 are energized. The conveyor wheel 4 transfers electrical energy to the steel wire 5 in contact with it, thereby energizing the steel wire 5 wound on several rollers 2. Copper ions in the electroplating solution are adsorbed onto the surface of the steel wire 5. At the same time, copper ions on the copper electrode plate 6 are continuously released into the electroplating solution in the electroplating tank 1. As the several rollers 2 continue to rotate, the steel wire 5 on the several rollers 2 are continuously conveyed in a spiral. In the horizontal and vertical directions, the steel wire 5 can contact the electroplating solution at different positions in the electroplating tank 1, thereby achieving a dynamic electroplating effect and improving the uniformity of electroplating. Meanwhile, the electroplated steel wire 5 is continuously fed out, and the steel wire 5 to be electroplated is continuously fed into the electroplating tank 1.

[0022] By spirally winding and conveying the steel wire 5 within the electroplating tank 1, the movement path of the steel wire 5 within the tank can be extended, thereby increasing the residence time of the steel wire 5. This facilitates sufficient copper plating on the surface of the steel wire 5, reduces the volume of the electroplating tank 1 and the space it occupies, and lowers the consumption of electroplating solution and electricity. At the same time, it facilitates increasing the conveying speed of the steel wire 5, thereby improving work efficiency. This movement of the steel wire 5 also allows it to contact the electroplating solution at different locations within the electroplating tank 1, thereby improving the uniformity of electroplating and ultimately improving the electroplating quality.

[0023] Furthermore, the processing equipment also includes a turntable 7, on which several rollers 2 are disposed, and the turntable 7 drives the several rollers 2 to rotate.

[0024] The turntable 7 is located outside the top opening of the electroplating tank 1, and the axis of the turntable 7 coincides with the center point between several rollers 2. When the turntable 7 rotates, it can drive several rollers 2 to perform synchronous circular motion. At this time, the several rollers 2 revolve, and the several rollers 2 continuously wind up and wrap new steel wires 5. At the same time, the several rollers 2 continuously release the steel wires 5 that have been electroplated outward, thereby enabling the several rollers 2 to actively convey the steel wires 5. Combined with the rotation of the rollers 2, the steel wires 5 can be conveyed in the vertical direction, avoiding the accumulation of steel wires 5 at a certain position on several rollers 2 when the steel wires 5 are continuously wound at a fixed point, thus preventing them from forming a spiral distribution.

[0025] The circular motion of several rollers 2 can also agitate the electroplating solution in the electroplating tank 1, causing it to rotate and flow. This allows the electroplating solution to continuously wash the copper electrode plate 6, ensuring that copper ions are evenly distributed in the electroplating solution and improving the electroplating effect.

[0026] Furthermore, the turntable 7 is provided with a plurality of sliders 8 that slide along the radial direction of the turntable 7, and the roller 2 is rotatably mounted on the sliders 8; A support frame 9 is provided on the electroplating tank 1, and a core column 10 is provided on the support frame 9. The core column 10 passes through the turntable 7 and extends into the space between several rollers 2. The turntable 7 is slidably set on the core column 10. The turntable 7 and the core column 10 are connected by a spring 11. Several connecting rings 12 are rotatably mounted on the core column 10, and the connecting rings 12 are rotatably connected to each roller 2 through an inclined pull arm 13.

[0027] The support frame 9 provides support for the turntable 7 and the core column 10. Several inclined arms 13 on the roller 2 are parallel to each other. Spring 11 provides elastic force to the turntable 7, causing the turntable 7 and the core column 10 to have a relative motion tendency. The turntable 7 drives the roller 2 and the core column 10 to have a relative motion tendency. Several inclined arms 13 between the roller 2 and the core column 10 can provide lateral thrust to the roller 2, thereby adjusting the distance between the axes of the roller 2 and the core column 10. The roller 2 can drive the slider 8 to slide on the turntable 7. Since several rollers 2 are connected to the core column 10 at the same time, several rollers 2 move closer or further away from each other synchronously. This makes it easy to adjust the diameter of the spiral winding of the steel wire 5. At the same time, the spring 11 can be used to spread the steel wire 5 on several rollers 2 outward, so that the steel wire 5 is in a taut state and prevents the steel wire 5 from loosening and slipping off the roller 2.

[0028] In practical use, the conveying of steel wire 5 can be combined with an external damper structure to ensure that steel wire 5 is always taut.

[0029] Furthermore, a conical disc 14 and a conical wheel 15 are respectively provided on the core column 10 and each of the rollers 2. The conical wheel 15 is slidably arranged on the roller 2. The conical wheel 15 is connected to the roller 2 by a spring 2 16. The core column 10 and the roller 2 are driven by the conical disc 14 and the conical wheel 15.

[0030] The contact surfaces of the conical disc 14 and the conical wheel 15 are inclined. When the turntable 7 makes a circular motion, the position of the core column 10 is fixed. At this time, the roller 2 drives the connecting ring 12 to rotate on the core column 10 through the inclined pull arm 13, and the conical wheel 15 rolls on the conical disc 14. The conical wheel 15 drives the roller 2 to rotate. Since the distance between the rollers 2 is adjustable, the inclined contact mode between the conical disc 14 and the conical wheel 15 and the force provided by the spring 16 to the conical wheel 15 can ensure that the conical wheel 15 and the conical disc 14 are always mutually driven. Furthermore, by adjusting the distance between the rollers 2, the rotation speed of the roller 2 and the spiral conveying speed of the wire 5 can be adjusted.

[0031] Furthermore, a side push ring 17 is provided inside the electroplating tank 1, which can reciprocate in the vertical direction and rotate synchronously with the turntable 7. Several connecting arms 18 are provided inside the side push ring 17, and each connecting arm 18 is provided with a rolling group. The rolling group is correspondingly provided with the roller 2. The rolling group consists of two rolling columns 19 used to lock the roller 2.

[0032] Two rolling pins 19 can be locked on both sides of the corresponding roller 2. When the roller 2 revolves, it will push the two rolling pins 19 and the side push ring 17 to move in a circular motion in sync. The rotation of the roller 2 will drive the rolling pins 19 to rotate in sync. The connecting arm 18 can be used to connect the rolling pins 19 and the side push ring 17. The rolling pins 19 can be set on the connecting arm 18 through the retainer 25.

[0033] In use, the rolling column 19 contacts the steel wire 5 wound on the outer wall of the roller 2. When the side push ring 17 moves back and forth in the vertical direction, the rolling column 19 can push the steel wire 5 in a certain area on the outer wall of the roller 2 to roll on the roller 2. This causes the steel wire 5 to change position towards the outer wall inside some rollers 2 and towards the outer wall outside some rollers 2, so that each position on the steel wire 5 can adsorb enough and uniform copper ions.

[0034] Furthermore, two sliding columns 20 are arranged opposite each other on the side push ring 17, and an annular groove is opened on the inner wall of the electroplating tank 1. The annular groove includes two groove groups arranged corresponding to the two sliding columns 20. The groove group consists of arc groove one 21, arc groove two 22 and transition groove 23. Arc groove one 21 and arc groove two 22 are staggered in the vertical direction, and arc groove one 21 and arc groove two 22 are both coaxially arranged with the turntable 7.

[0035] When the side push ring 17 rotates, it will drive the sliding column 20 to slide in the annular groove. When the sliding column 20 moves between the first arc groove 21 and the second arc groove 22, the side push ring 17 will be displaced in the vertical direction, thereby providing the rolling column 19 with reciprocating motion power in the vertical direction. The transition groove 23 can be used to connect the first arc groove 21 and the second arc groove 22.

[0036] Furthermore, the connecting arm 18 is a telescopic rod, and the rolling assembly is movable along the radial direction of the side push ring 17 via the telescopic rod. The rolling assembly and the side push ring 17 are connected by a spring piece 24.

[0037] Since the distance between several rollers 2 is adjustable, in order to ensure that the rolling group and the rollers 2 always cooperate with each other, the position between the rolling group and the side push ring 17 also needs to be adjustable. Here, the rolling group is supported by a telescopic rod, and the rolling group is provided with elastic force by a spring plate 24, so that the two rolling columns 19 in the rolling group are always stuck on the corresponding rollers 2.

[0038] Furthermore, a transmission ring 26 and a transmission wheel 27 are provided on the turntable 7 for mutual transmission connection. The transmission wheel 27 is provided with a retaining edge for locking the transmission ring 26. A drive motor 28 is provided on the support frame 9. The output end of the drive motor 28 is connected to the transmission wheel 27 through a transmission shaft 29. The transmission wheel 27 is connected to the support frame 9 through a spring 30.

[0039] The drive motor 28 provides rotational power to the transmission ring 26 and the turntable 7 via the transmission shaft 29 and the transmission wheel 27, thereby driving the roller 2 to rotate and revolve. When the position of the turntable 7 changes in the vertical direction, the transmission ring 26 can drive the transmission wheel 27 to move synchronously, and the transmission ring 26 and the transmission wheel 27 always maintain a transmission state. The drive motor 28 can always provide power to the transmission wheel 27 with the help of the transmission shaft 29. The spring 30 can provide auxiliary elastic force to the transmission wheel 27 to improve the stability of the transmission ring 26 and the transmission wheel 27 during transmission. When the transmission shaft 29 is a telescopic rod, it can directly connect the transmission wheel 27 and the drive motor 28. When the transmission shaft 29 is a single cylindrical structure, the transmission wheel 27 can be slidably mounted on the transmission shaft 29, and the transmission wheel 27 rotates synchronously with the transmission shaft 29.

[0040] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
