Description

Technical Field

[0001] The invention belongs to the technical field of plating of metal materials, and in particular relates to a broken wire re-leading device applied to a steel wire electroplating production line and a steel wire electroplating production line. Background Art

[0002] The electroplating production line for cutting steel wires generally operates multiple steel wires simultaneously. With the continuous improvement of the process, the wire diameter of the cutting steel wire is getting thinner and thinner. At present, it can reach a diameter of about 0.04mm. With the reduction of the wire diameter of the cutting steel wire, the wire diameter of the parent material used for wet-drawn ultra-fine cutting steel wire has also been reduced to below 0.5mm. Due to the small wire diameter, the change in surface stress of the steel wire after electroplating makes it easy for the wire to break at the cathode roller at the outlet of the aqueduct. Once the wire is broken, the steel wire that loses traction will accumulate and entangle, affecting the normal production of other steel wires. In order to avoid the above problems, the traditional practice is to use a detection device to detect the tension of each steel wire. When the tension of a steel wire disappears, it means that the steel wire is broken, and the machine is immediately shut down. After the operator connects the broken ends of the steel wire, production can be resumed. Although this method can effectively avoid the influence of broken wire on other steel wires, it seriously affects production efficiency. Especially when heat treatment and electroplating are on the same assembly line, downtime will cause the steel wire in the heat treatment section to be scrapped, seriously affecting the normal operation of the entire assembly line.

DETAILED DESCRIPTION

[0023] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 , Figure 2 and Figure 4The figure shows a specific structure of the broken wire rewinding device applied to the steel wire electroplating production line of the present invention, which is used for the broken wire rewinding of the steel wire with a diameter less than 0.5 mm on the steel wire electroplating production line. The device includes a bracket 1, a traction roller 2 rotatably connected to the bracket 1, a drive motor 3 fixedly connected to the bracket 1 and transmission connected to the traction roller 2, at least one wire pressing roller 4 arranged parallel to the traction roller 2, a force applicator 5 for driving the wire pressing roller 4 to press or separate from the roller surface of the traction roller 2, a tension detector 6 and a power supply 7 for providing electric energy to the drive motor 3 and the force applicator 5. When the wire pressing roller 4 is separated from the traction roller 2, a wire passing channel 8 is formed between the two, and the steel wire 18 passes through the wire passing channel 8 when running. The force applicator 5 is fixedly connected to the bracket 1, and the two ends of each wire pressing roller 4 are rotatably connected to a roller frame 14. The action part of the force applicator 5 is connected to the roller frame 14 to drive the roller frame 14 to move. The bracket 1 is provided with an inlet 9 and an outlet 10. The inlet 9 and the outlet 10 are respectively arranged at the upstream and downstream ends of the wire passing channel 8 and are respectively connected to the wire passing channel 8. The tension detector 6 is located upstream of the inlet 9, and the tension detector 6 is fixedly connected to the bracket 1. The tension detector 6 is connected to a controller 11 to send the detected wire tension to the controller 11. The controller 11 is electrically connected to the force applicator 5 and the drive motor 3 respectively to control the action of the force applicator 5 and the drive motor 3. The power supply 7 provides electrical energy to the controller 11. The roller surface of the traction roller 2 is fixedly wrapped with an adhesive layer 12 for bonding the steel wire and driving the steel wire to be wound on the traction roller 2.

[0025] The power supply 7 is used to supply power to various electrical components in the broken wire re-drawing device described in this embodiment.

[0026] The tension detector 6 described in this embodiment is also called a tension sensor, which is a mature outsourced product and belongs to the prior art, and will not be described here. The tension detector 6 is preferably a torque type.

[0027] In this embodiment, in order to simplify the structure, the number of the crimping roller 4 is preferably one, the force applicator 5 is a cylinder, the action part of the force applicator 5 - the piston rod 501 is connected to the roller frame 14, and pushes the roller frame 14 to move back and forth along the radial direction of the traction roller 2, the force applicator 5 is connected to the air source 503 through the first control valve 502, the first control valve 502 is connected to the controller 11 and is controlled by the controller 11, and a lubricating sleeve 15 is fixedly provided on the roller surface of the crimping roller 4. The lubricating sleeve 15 is a fluoroplastic sleeve with a smooth surface, which has an anti-adhesion effect and will not allow the adhesive on the adhesive layer 12 to stick to the lubricating sleeve 15.

[0028] As an improvement to the above technical solution, in order to improve the bonding effect between the steel wire and the adhesive layer 12 on the surface of the traction roller 2, the number of the pressing rollers 4 can be set to two, such as Figure 3As shown. When the force applicator 5 drives the roller frame 14 to move toward the traction roller 2, the two pressing rollers 4 are simultaneously pressed against the roller surface of the traction roller 2. The use of two pressing rollers 4 can press and bend the steel wire, so that the steel wire fits on the adhesive layer 12 on the surface of the traction roller 2, making it easier for the traction roller 2 to drive the steel wire to wind and continue to pull the steel wire.

[0029] In actual production, the structure of the bracket 1 is not unique, as long as it can achieve the fixation and support of the traction roller 2, the drive motor 3, the force applicator 5 and the tension detector. The bracket 1 in this embodiment includes two side plates 101 arranged in parallel and opposite to each other and a top plate 102 connected to the same end of the two side plates 101. The traction roller 2 is arranged between the two side plates 101, and the roller shafts at both ends of the traction roller 2 are rotatably connected to the two side plates 101 respectively. The drive motor 3 is fixedly connected to the side of one of the side plates 101 facing away from the traction roller 2. The roller frame 14 includes two The bracket 1 comprises two support plates 14a arranged in parallel and opposite to each other, and a connecting plate 14b connected to the same end of the two support plates 14a, the crimping roller 4 is arranged between the two support plates 14a, and the roller shafts at both ends of the crimping roller 4 are rotatably connected to the two support plates 14a respectively, and the connecting plate 14b is arranged parallel to the top plate 102, and the roller surface of the crimping roller 4 is exposed outside the roller frame 14, and the entire roller frame 14 is located inside the bracket 1, and the force applicator 5 is fixedly connected to the top plate 102, and the piston rod 501 of the force applicator 5 passes through the top plate 102 and is fixedly connected to the connecting plate 14b.

[0030] In this embodiment, one of the two side panels 101 extends toward the upstream direction of the wire-passing channel 8 to form an extension portion 103, and the tension detector 6 is fixedly connected to the extension portion 103 to detect the tension of the steel wire upstream of the wire-passing channel 8, and the other side panel is detachably connected to the top panel 102 and the roller shaft of the traction roller 2. When guiding the steel wire through the wire-passing channel 8 and cleaning the steel wire wound on the traction roller 2, the side panel 101 can be removed, so that the steel wire can be embedded into the wire-passing channel 8 from one end of the traction roller 2, which is convenient for the threading of the steel wire and more convenient for cleaning the steel wire wound on the traction roller 2, such as directly peeling off the adhesive layer 12 from the traction roller 2.

[0031] The side plate 101 and the top plate 102 can be connected by fastening with screws 17 .

[0032] In order to provide a wire breakage reminder to the operator, in this embodiment, an alarm 13 is preferably connected to the bracket 1, and the alarm 13 is electrically connected to the controller 11 and controlled by the controller 11. The alarm is preferably an audible and visual alarm.

[0033] In order to further improve the bonding effect of the adhesive layer 12 on the steel wire, the present embodiment further discretely arranges a plurality of double-sided tapes 16 arranged in sequence around the circumference of the lubricating sleeve 15 on a crimping roller 4, and any double-sided tape 16 extends along the axial direction of the lubricating sleeve 15. Since the lubricating sleeve 15 has anti-adhesive properties, the bonding force of the double-sided tape 16 on the lubricating sleeve 15 is relatively small. When the crimping roller 4 is crimped onto the traction roller 2, the double-sided tape 16 is bonded to the adhesive layer 12 and separated from the lubricating sleeve 15, sandwiching the steel wire in the middle, thereby stably clinging the steel wire to the adhesive layer 12 on the surface of the traction roller 2. As the traction roller 2 rotates, the steel wire is driven to be wound around the traction roller 2.

[0034] In order to prevent the wire from being broken and being pulled so that it cannot be smoothly wound onto the pulling roller 2, the present embodiment further provides a pair of scissors 19 at the downstream end of the bracket 1. Figure 3~Figure 5 As shown, the pin shaft 20 of the two blade heads of the scissors 19 extends to a mounting plate 21 and is fixedly connected to the mounting plate 21, and the mounting plate 21 is fixedly connected to the bracket 1. The two handles of the scissors 19 are respectively hinged with a connecting rod 22, and the free ends of the two connecting rods 22 are hinged to the front end of a push rod of a cylinder 23. The cylinder 23 is connected to the air source 503 through the second control valve 24, and the second control valve 24 is connected to the controller 11 and is controlled by the controller 11. The two blade heads of the scissors 19 are opened and placed on both sides of the steel wire. When the steel wire 18 breaks, the tension of the steel wire 18 will drop suddenly. At this time, the controller 11 controls the force applicator 5 to operate, driving the wire pressing roller 4 to press the steel wire 18 against the traction roller 2. At the same time, the controller 11 controls the cylinder 23 to operate, and the cylinder 23 drives the scissors 19 to cut the steel wire 18. Then the controller 11 controls the drive motor 3 to drive the traction roller 2 to rotate rapidly at a linear speed exceeding the conveying speed of the steel wire 18, and winds up the steel wire 18 until the tension detected by the tension detector 6 returns to a level close to normal. Then the controller 11 controls the drive motor 3 to drive the traction roller 2 to rotate at a linear speed equal to the conveying speed of the steel wire 18, so that the tension detected by the tension detector 6 is maintained at a normal level.

[0035] The working process of the present invention is: Figure 1~Figure 5As shown, the broken wire re-guiding device applied to the steel wire electroplating assembly line of the present invention is fixedly installed on the steel wire electroplating assembly line to guide the steel wire 18 to run from the wire inlet 9 to the wire outlet 10 through the wire passage 8. At the same time, the tension detector 6 is used to detect the tension of the steel wire 18 running in the normal production process, and the detection result is sent to the controller 11, and the controller 11 monitors the tension change. When the controller 11 finds that the tension of the steel wire 18 suddenly changes and cannot be restored in a short time, the driving motor 3 and the force applicator 5 are immediately started, and the driving motor 3 drives the traction roller 2 to rotate. The roller surface linear speed of the traction roller 2 is higher than the travel speed of the steel wire 18 at the beginning, and then decreases according to the tension of the steel wire 18 until it is consistent with the travel speed of the steel wire 18. The force applicator 5 drives the roller frame 14 to drive the pressure roller 4 to press the adhesive layer 12 on the traction roller 2, and the steel wire 18 is pressed tightly against the adhesive layer 12. The steel wire 18 is adhered by the adhesive layer 12 on the traction roller 2, and then is driven to be wound on the traction roller 2. After the operator arrives at the scene, the steel wire 18 is cut off from the upstream of the broken wire re-drawing device, the rotation of the traction roller 2 is stopped, the pressure roller 4 is reset, and then the steel wire 18 is redirected to pass through the wire passing channel 8 and then pulled downstream to the winding mechanism. After the steel wire 18 operates normally, the residual steel wire on the traction roller 2 is cleared, the tension detection state of the tension detector 6 on the steel wire 18 is restored, and the re-drawing device is restarted.

[0036] After the double-sided tape 16 is adhered to the surface of the lubricating sleeve 15 sleeved on the crimping roller 4, when the crimping roller 4 is crimped onto the traction roller 2, the double-sided tape 16 is transferred from the surface of the lubricating sleeve 15 to the adhesive layer 12, so that the steel wire 18 is tightly attached between the adhesive layer 12 and the double-sided tape 16, ensuring that the steel wire 18 is rolled up by the traction roller 2, restoring the state of the steel wire 18 being pulled.

[0037] When the alarm 13 is provided on the support 1 , when the steel wire 18 is broken, the controller 11 controls the alarm 13 to sound an alarm, reminding the operator to respond quickly to avoid too much waste wire being entangled on the traction roller 2 .

[0038] In actual use, the driving motor 3 is preferably a magnetic powder motor, so that the rotation speed of the driving motor 3 can be changed according to the tension of the steel wire 18 to prevent the steel wire 18 from being broken.

[0039] When the scissors 19 are arranged at the downstream end of the bracket 1, when the controller 11 detects that the steel wire 18 is broken, the piston rod 501 of the force applicator 5 is immediately controlled to extend through the first control valve 502, pushing the wire pressing roller 4 and the traction roller 2 to press against each other to press the steel wire 18, and at the same time controlling the alarm 13 to sound an alarm. At this time, regardless of whether the unwinding mechanism 25 is unwinding, the steel wire located upstream of the broken wire re-drawing device 100 no longer moves downstream, but becomes loose. In a short time after the pressure roller 4 and the traction roller 2 are pressed against each other, the controller 11 controls the cylinder 23 to retract, drives the two connecting rods 22 to move closer, closes the two blades of the scissors 19, and cuts the steel wire 18. Subsequently, in a very short time, the controller 11 controls the drive motor 3 to rotate at a higher speed, drives the traction roller 2 to rotate at a linear speed exceeding the normal conveying speed of the steel wire 18, and tightens the relaxed steel wire 18 again, until the tension detected by the tension detector 6 is restored to a near normal level, the controller 11 controls the drive motor 3 to drive the traction roller 2 to rotate at a linear speed equal to the conveying speed of the steel wire 18, so that the tension detected by the tension detector 6 is maintained at a normal level. The controller 11 controls the drive motor 3 to move and drives the cylinder 23 to reset.

[0040] According to the description of the above working process, it can be seen that during use, the present invention does not need to shut down the steel wire production line, and will not cause the steel wire to break and accumulate and entangle. This effectively solves the current technical problem of needing to shut down to avoid accumulation and entanglement caused by steel wire breakage.

[0041] Embodiment 2:

[0042] like Figure 6 The figure shows a steel wire electroplating production line, including an unwinding mechanism 25, an electroplating tank 26, and a winding mechanism 27 which are arranged in sequence from upstream to downstream, wherein an anode plate 28 is arranged in the electroplating tank 26, and a cathode roller 29 is respectively arranged above the upstream and downstream ends of the electroplating tank 26, and a roller 30 is respectively arranged on both sides below each cathode roller 29, and any cathode roller 29 abuts against the two rollers 30 below it, and the cathode roller 29 and the roller 30 are fixedly connected to the electroplating tank 26 through a support 31, and the broken wire re-guiding device 100 described in Example 1 is arranged on the upstream side of the cathode roller 29 located downstream, and the broken wire re-guiding device 100 is fixedly connected to both sides of the electroplating tank through a crossbeam 32 spanning the electroplating tank 26.

[0043] The working process of this embodiment is: after the steel wire 18 is unwound by the unwinding mechanism 25, it passes through the cathode roller 29 and the roller 30 located upstream and enters the electroplating tank 26 for electroplating. The electroplated steel wire passes through the broken wire re-guiding device 100 and is wound onto the rewinding mechanism 27 through the downstream cathode roller 29 and the roller 30. The steel wire 18 abuts against the tension detector 6 of the broken wire re-guiding device 100. The unwinding mechanism 25 is passively unwound under the traction of the rewinding mechanism 27, and the unwinding mechanism 25 can provide a certain braking force, so that the steel wire 18 has a certain tension. The tension of the steel wire 18 is detected by the tension detector 6 and sent to the controller 11.

[0044] During normal operation, the tension detected by the tension detector 6 fluctuates within a very small range, and the controller 11 determines that the steel wire 18 is in a normal electroplating state. After electroplating, the steel wire 18 is prone to breakage at the downstream cathode roller 29. When the steel wire 18 breaks, although the steel wire 18 is crimped and driven by the cathode roller 29, the tension generated by the driving force of the cathode roller 29 on the steel wire 18 is much smaller than the tension generated by the winding mechanism 27 on the steel wire 18. Therefore, the tension detector 6 will detect a sudden change in the tension of the steel wire 18, and the sudden change is irreversible. At this time, the controller 11 determines that the steel wire 18 is in a broken state, and immediately controls the piston rod 501 of the force applicator 5 to extend through the first control valve 502, pushing the wire pressing roller 4 and the traction roller 2 to press against each other, pressing the steel wire 18, and controlling the alarm 13 to alarm at the same time. At this time, regardless of whether the unwinding mechanism 25 is unwinding, the steel wire located upstream of the broken wire re-drawing device 100 no longer moves downstream, but becomes loose. In a short time after the pressure roller 4 and the traction roller 2 are pressed against each other, the controller 11 controls the cylinder 23 to retract, drives the two connecting rods 22 to move closer, closes the two blades of the scissors 19, and cuts the steel wire 18. Subsequently, in a very short time, the controller 11 controls the drive motor 3 to rotate at a higher speed, drives the traction roller 2 to rotate at a linear speed exceeding the normal conveying speed of the steel wire 18, and tightens the relaxed steel wire 18 again, until the tension detected by the tension detector 6 is restored to a near normal level, the controller 11 controls the drive motor 3 to drive the traction roller 2 to rotate at a linear speed equal to the conveying speed of the steel wire 18, so that the tension detected by the tension detector 6 is maintained at a normal level. The controller 11 controls the drive motor 3 to move and drives the cylinder 23 to reset.

[0045] The specific working process of the broken wire re-guiding device 100 can refer to the specific working process in Example 1.

[0046] After the operator is in place, the steel wire 100 is cut off from the upstream of the broken wire re-guiding device 100, and then the steel wire 100 is re-pulled to pass through the downstream cathode roller 29 and the supporting roller 30, and then wound onto the winding mechanism 27 for winding, and then the broken wire re-guiding device 100 is stopped and reset, the side plate 101 is removed, the steel wire 18 wound on the traction roller 2 is removed, and the normally transported steel wire 100 is moved into the wire passing channel 8, and finally the side plate 101 is installed, and the broken wire re-guiding device 100 is started again to monitor the electroplating process of the steel wire 18.

[0047] The above embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
