Description

Technical Field

[0001] This invention relates to a steel cord electroplating apparatus, specifically to a high-efficiency processing apparatus for ultra-high toughness tire bead steel cord electroplating. Background Technology

[0002] Steel cord is a fine-gauge steel wire or rope made of high-quality high-carbon steel with a brass-plated surface, and designed for special purposes. It is the most widely used rubber reinforcing material, primarily used in passenger car tires, light truck tires, heavy-duty truck tires, construction machinery tires, aircraft tires, and other rubber product reinforcing materials. Radial tires made with steel cord as reinforcement have advantages such as long service life, high speed, puncture resistance, good elasticity, safety, comfort, and fuel efficiency. Current steel cord production requires electroplating of the steel cord surface. Electroplating is a process that uses electrolysis to deposit a thin layer of other metals or alloys onto the surface of the steel wire. It utilizes electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing corrosion and improving durability. Because the distance between the steel wire and the copper particles varies in the plating bath, the current distribution in the bath is also different, resulting in uneven concentration of metal ions in the electroplating solution. This affects the electroplating effect on the steel wire; therefore, the distance between the steel wire and the copper particles plays a crucial role in the coating thickness.

[0003] In existing copper-plated steel wire electroplating lines, the steel wire enters and exits the plating tank in a straight line. Due to the inconsistent distance between the upper and lower surfaces of the steel wire and the copper particles in the plating tank, the steel wire plating layer is uneven. Some companies install stirring devices or use rotating plating tanks in the electroplating solution to ensure uniform distribution of metal ions. However, stirring devices or rotating plating tanks can affect the path of metal ions in the solution and also affect the uniformity of the steel cord plating layer. Furthermore, the feed reel is not easy to switch, which reduces processing efficiency.

[0004] In view of this, the present invention designs a high-efficiency processing device for electroplating ultra-high toughness tire bead steel cord. Summary of the Invention

[0005] The main objective of this disclosure is to provide a high-efficiency electroplating device for ultra-high toughness tire bead steel cord, so as to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-efficiency electroplating device for ultra-high toughness tire bead steel cord includes a steel cord body, a device mounting plate, a wiring platform, an electroplating tank, and wire feeding rollers. A quick-change mechanism for the wire feeding rollers is provided between the device mounting plate and the wiring platform. Several wire feeding rollers are detachably mounted on the quick-change mechanism. The steel cord body is wound around the surface of the wire feeding rollers. Two main wire rollers are movably mounted on the wiring platform, arranged symmetrically at different heights. Several first guide rollers are also movably mounted on the wiring platform. Threading holes are provided on both sides of the electroplating tank. The other end of the steel cord body passes sequentially through the first guide rollers, the main wire rollers, and the threading holes on both sides. An electroplating mechanism is provided inside the electroplating tank. Mounting holes are provided on the device mounting plate.

[0007] Preferably, the electroplating mechanism includes an annular sealing groove, copper particles, and electrode rollers. The annular sealing groove is fixedly installed at the bottom of the electroplating tank, and the copper particles are evenly distributed in the annular sealing groove. Several evenly distributed electrode rollers are movably installed in the electroplating tank, and the portion of the steel cord body that passes through the electroplating tank contacts the electrode rollers.

[0008] Preferably, a bracket is fixedly installed on the right side of the electroplating tank, and the bracket corresponds to the position of the wire hole on the right side. A second guide wheel is movably installed on the bracket, and the right end of the steel cord body passes around the second guide wheel.

[0009] Preferably, both sides of the electroplating tank are provided with annular grooves, and several rotating rods arranged in a circular array are slidably installed in the annular grooves. A rotating disk is fixedly installed at the other end of the rotating rod. An annular hole is provided at the center of each of the two rotating disks, and several evenly distributed actuating posts are fixedly installed on one side of the inner wall of the annular hole. The other side of the annular hole is smooth. The steel cord body passes through the annular hole and its surface contacts the actuating posts. The two rotating disks rotate in opposite directions.

[0010] Preferably, a reciprocating shaft is rotatably mounted on the side wall of the electroplating tank, and a rotating wheel is fixedly mounted on the other end of the reciprocating shaft. A first gear is fixedly mounted on the surface of the rotating wheel, and a second gear is fixedly mounted on the outer side of the rotating disc. The first gear and the second gear mesh and drive each other. A torsion spring is sleeved on the reciprocating shaft, and the two ends of the torsion spring are respectively fixedly connected to the side of the rotating wheel and the inner wall of the electroplating tank.

[0011] Preferably, a small electric push rod is fixedly installed on the inner bottom wall of the electroplating tank, a sliding groove is opened on the outer side of the annular sealing groove, and a first fixing block is slidably installed in the sliding groove. The output end of the small electric push rod is fixedly connected to a second fixing block, and an active motor is fixedly installed on the second fixing block. The output end of the active motor is fixedly connected to a drive shaft, and the drive shaft is rotatably connected to the first fixing block. A first friction wheel is fixedly installed on the drive shaft, and a second friction wheel is fixedly installed on the drive shaft, with the second friction wheel in contact with the first friction wheel.

[0012] Preferably, the quick switching mechanism for the wire feeding reel includes a switching base plate, Y-shaped supports, and a connecting horizontal plate. There are two switching base plates, and three sets of horizontally equidistant Y-shaped supports are fixedly installed on each switching base plate. Each set of Y-shaped supports includes two Y-shaped supports, which are arranged front and back. A roller mounting groove is opened at the end of the Y-shaped support away from the switching base plate. The front and rear roller shafts of the wire feeding roller extend into the two roller mounting grooves on each set of Y-shaped supports, respectively. A connecting horizontal plate is fixedly connected between the two switching base plates. Two through holes are opened on the upper switching base plate, and the through holes are located diagonally below the upper wire feeding roller.

[0013] Preferably, an X-axis one-way lead screw is rotatably mounted between the device mounting plate and the wiring platform, and a connecting transverse plate is threaded onto the X-axis one-way lead screw. An X-axis guide shaft parallel to the X-axis one-way lead screw is fixedly connected between the wiring platform and the device mounting plate. The connecting transverse plate is slidably mounted on the X-axis guide shaft. A servo control motor is fixedly mounted on the wiring platform, and the output end of the servo control motor is fixedly connected to the X-axis one-way lead screw.

[0014] In view of this, compared with the prior art, the beneficial effects of the present invention are: (i) In this application, during the initial electroplating, the first unwinding roller is located at the unwinding station, and the steel cord on it is pulled out and passes through the electroplating tank. The second guide roller guides the steel cord body and can be wound by an external winding device. The electroplating part of the steel cord is located in the electroplating solution in the electroplating tank. The electrode roller supports the steel cord body to make the steel cord relatively straight, so that the copper particles can play a uniform role. The two steel cord bodies can be electroplated at the same time to ensure the efficiency of the process.

[0015] (ii) In this application, during the electroplating process, the active motor works and drives the drive shaft to rotate. The two drive shafts rotate in opposite directions. The first friction wheel is driven to rotate, causing the second friction wheel to rotate as well. Then the reciprocating shaft rotates, causing the first gear on the wheel to drive the second gear to rotate. As a result, the flipping disc rotates, and the self-rotating rod slides in the annular groove, causing each actuating column to actuate the steel cord body. The flipping discs on both sides rotate in opposite directions, which allows the steel cord body to be "twisted," that is, the steel cord body can be repeatedly flipped over to make the electroplating on its surface more uniform and improve the processing quality.

[0016] (III) In this application, after the first electroplating is completed, the small electric push rod works to reduce the height of the active motor. The second fixed block slides down, causing the first friction wheel to disengage from the second friction wheel. Under the elastic reset action of the torsion spring, the reciprocating shaft returns to its original state, and the steel cord body returns to a straight state. The wire feeding roller continues to feed the wire to realize the second electroplating process. That is, the part that was electroplated in the previous time is pulled out of the electroplating tank, and the part that needs to be electroplated in the second time is sent into the electroplating tank. This process is repeated to realize the continuous electroplating of the steel cord body.

[0017] (iv) In this application, when the steel cord on the first pay-off roller is used up, the servo control motor works to make the X-axis unidirectional screw rotate. Then the connecting transverse plate will move along the X-axis guide axis toward the wire table. The switching base plate drives the Y-type support to move until the second pay-off roller moves to the pay-off position, and the steel cord on it can be used. This makes it easy to switch pay-off rollers. After all pay-off rollers are used up, they can be replaced uniformly. Disassembly and assembly are very simple. Attached Figure Description

Two switching base plates 501 are provided, and three sets of transversely equidistantly distributed Y-shaped supports 502 are fixedly installed on each switching base plate 501. Each set of Y-shaped supports 502 includes two Y-shaped supports 502 arranged front-to-back. A roller mounting groove is provided at the end of the Y-shaped support away from the switching base plate 501. The front and rear roller shafts of the pay-off reel 5 extend into the two roller mounting grooves on each set of Y-shaped supports 502, respectively.

[0026] The specific implementation of this embodiment is as follows: During the initial electroplating, the first unwinding roller 5 is located at the unwinding station, and the steel cord on it is pulled out and passes through the electroplating tank 4. The second guide roller 405 guides the steel cord body 1 and can be wound by an external winding device. The electroplating part of the steel cord is located in the electroplating solution in the electroplating tank 4. The electrode roller 403 supports the steel cord body 1 to make the steel cord relatively straight, so that the copper particles 402 can play a uniform role. The two steel cord bodies 1 can be electroplated at the same time to ensure the efficiency of the process. During electroplating, the active motor 607 operates, driving the drive shaft 608 to rotate. The two drive shafts 608 rotate in opposite directions, causing the first friction wheel 609 to rotate, which in turn causes the second friction wheel 609 to rotate. Subsequently, the reciprocating shaft 602 rotates, causing the first gear 605 on the rotating wheel 603 to drive the second gear to rotate. This causes the flipping disc 6 to rotate, and the rotating rod 601 slides in the annular groove, causing each actuating column 7 to actuate the steel cord body 1. Since the flipping discs 6 on both sides rotate in opposite directions, the steel cord body 1 can be "twisted," meaning it can be repeatedly flipped over to make the electroplating on its surface more uniform and improve the processing quality. After the first electroplating is completed, the small electric push rod 606 operates to lower the height of the active motor 607. The second fixed block slides downward, causing the first friction wheel 609 to disengage from the second friction wheel 610. Under the elastic reset action of the torsion spring 604, the reciprocating shaft 602 returns to its original state, and the steel cord body 1 returns to a straight state. The wire feeding roller 5 continues to feed the wire to achieve the second electroplating process. That is, the part that was electroplated in the previous time is pulled out of the electroplating tank 4, and the part that needs to be electroplated in the second time is sent into the electroplating tank 4. This process is repeated to achieve continuous electroplating of the steel cord body 1. When the steel cord on the first feed roller 5 is used up, the servo control motor 504 works, causing the X-axis one-way lead screw 505 to rotate. The connecting transverse plate 503 will then move along the X-axis guide shaft 506 toward the wiring table 3. The switching base plate 501 drives the Y-shaped support 502 to move until the second feed roller 5 moves to the feed position, where the steel cord can be used. This makes it easy to switch feed rollers 5. Once all feed rollers 5 are used up, they can be replaced uniformly. Disassembly and assembly are very simple.
