Description

Technical Field

[0001] This invention relates to the field of straightening facilities, and more particularly to a copper wire straightening device and method for cable processing. Background Technology

[0002] Cable is a wire product used to transmit electrical energy, information, and realize electromagnetic energy conversion. It has the characteristics of being internally energized and externally insulated, and can safely and stably transmit power or signals in various environments. During cable processing, straightening equipment is often used to straighten the inner core, such as copper wire.

[0003] However, during the long straightening process, hard particles such as oxide scale will be generated on the surface of the straightening rollers and power rollers on the straightening equipment. The presence of hard particles will cause the surface of the straightening rollers and power rollers to be rough, resulting in scratches on the surface of the copper wire during the straightening process, which seriously affects the product quality. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a copper wire straightening device and method for cable processing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a copper wire straightening device for cable processing, comprising a device base, two wire feeding power wheels symmetrically arranged on one side of the upper end of the device base, two wire pulling power wheels symmetrically arranged on the other side of the upper end of the device base, a plurality of straightening wheels arranged in a staggered manner in the middle of the upper end of the device base, an adapting component provided at the front edge of the upper end of the device base, two fixed frames symmetrically connected to the adapting component, a drive shaft rotatably mounted through the inner side of the end of the fixed frame, a brush frame rotatably mounted on the outer side of the end of the fixed frame, a steel brush mounted on the lower end of the brush frame, a transmission shaft rotatably mounted on the side of the brush frame, the transmission shaft being connected to the steel brush and the drive shaft respectively, a pawl extending from the upper end of the transmission shaft, a trapezoidal frame rotatably mounted on the end of the pawl, the end of the trapezoidal frame being rotatably connected to one side of the fixed frame, and an air blowing component mounted on the other side of the fixed frame.

[0006] Preferably, the air blowing component includes an arc-shaped air shell mounted on the other side of the fixed frame. A piston is slidably mounted inside the arc-shaped air shell. An arc-shaped column extends from the middle of the piston and passes through one end of the arc-shaped air shell. The arc-shaped column is slidably engaged with the arc-shaped air shell, and the end of the arc-shaped column is fixed to the brush holder.

[0007] Preferably, the arc-shaped air housing has multiple air nozzles evenly distributed and fixedly connected at the edge of the end face of the straightening wheel, the air nozzles are inclined, and a connecting frame is fixedly installed in the middle of the arc-shaped air housing, the end of the connecting frame is fixed to the fixing frame.

[0008] Preferably, the lower end face of the drive shaft and the end of the brush shaft of the steel brush are coaxially inlaid with helical gears, the two helical gears mesh with each other, the lower end of the drive shaft is coaxially inlaid with a large-diameter pulley, the upper outer surface of the drive shaft is coaxially inlaid with a small-diameter pulley, and a synchronous belt connects the small-diameter pulley and the large-diameter pulley.

[0009] Preferably, the adaptor includes an adjustment seat fixedly installed at the upper front edge of the equipment base. A T-shaped carrier is slidably installed inside the adjustment seat. An extended bracket extends from the upper end of the T-shaped carrier. A bolt is screwed through the end of the extended bracket. The front end face of the adjustment seat has multiple fixed wheel grooves. The distribution spacing of the multiple fixed wheel grooves matches the distribution spacing between the feed power wheel, the straightening wheel, and the pull power wheel. The end of the bolt is inserted into the interior of one of the fixed wheel grooves.

[0010] Preferably, a support frame is fixedly installed on the upper end of the T-shaped carrier near the side of the protruding frame. A separating threaded rod is rotatably installed through the end of the support frame. A guide rod is embedded through the end of the support frame. The guide rod is located below the separating threaded rod. The threads at both ends of the separating threaded rod are symmetrically arranged. A separating seat is screwed onto one end of the separating threaded rod, and an adapting seat is screwed onto the other end of the separating threaded rod. Both the separating seat and the adapting seat are slidably installed on the outer surface of the guide rod.

[0011] Preferably, an adaptive threaded rod is rotatably mounted inside the adaptive seat, and an adaptive frame is screwed onto the outer surface of the adaptive threaded rod. The adaptive frame is slidably mounted inside the adaptive seat. A servo motor is fixedly mounted on the upper end of the adaptive frame and the end of the separation seat. The output end of the servo motor is fixed to the drive shaft, and the two fixed frames are fixed to the adaptive frame and the separation seat, respectively.

[0012] A method for using a copper wire straightening device for cable processing is also provided, including the following steps:

[0013] S1: Pass the copper wire between two input power wheels so that the copper wire is straightened by passing through multiple straightening wheels under the push of the two input power wheels. The straightened copper wire is then sent out by passing through two pull power wheels.

[0014] S2: During this process, the steel brush and arc-shaped air shell are moved to the infeed power wheel, straightening wheel or wire pulling power wheel using the adapter;

[0015] S3: Subsequently, the servo motor drives the steel brush and piston to move synchronously to remove hard particles such as oxide scale from the feed power wheel, straightening wheel and drawing power wheel to avoid scratching the surface of the copper wire.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The rotating drive shaft drives the transmission shaft to rotate, which in turn drives the steel brush to rotate, cleaning the grooves on the surface of the straightening wheel. During this process, the transmission shaft also drives the claw to rotate. At this time, the trapezoidal frame moves to adapt to the rotation of the claw, and the claw continuously pushes the brush holder, causing the brush holder to continuously swing in an arc around the drive shaft. This, in turn, drives the steel brush to continuously swing in an arc, cleaning the same position of the groove multiple times to remove hard particles such as oxide scale on the straightening wheel, thus avoiding scratches on the surface of the copper wire during straightening and improving product quality. At the same time, when the brush holder swings in an arc, it also drives the arc-shaped column to move, which in turn drives the piston to slide back and forth in the arc-shaped air shell, continuously drawing air into the arc-shaped air shell and spraying it out through the air nozzle. This blows the hard particles brushed off in the opposite direction of the copper wire, causing them to fall off, thus preventing the hard particles brushed off from still adhering to the straightening wheel and scratching the surface of the copper wire, thereby further improving product quality.

[0018] 2. By rotating the separating threaded rod, the separating seat and the adapting seat can be moved in opposite directions, allowing the steel brush and the arc-shaped air shell to disengage from the straightening wheel. Then, the bolt can be unscrewed from the fixed wheel groove, allowing the T-shaped carrier to slide within the adjusting seat to adjust the position of the steel brush and the arc-shaped air shell, moving them to the inlet power wheel, the pull power wheel, or another straightening wheel. Next, rotating the adapting threaded rod drives the adapting frame to move, which in turn moves the rear fixed frame, allowing the two fixed frames to be in a staggered or aligned state. This adapts to the staggered straightening wheel or the aligned inlet power wheel and pull power wheel for cleaning, thus meeting the usage requirements. Attached Figure Description

[0028] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] like Figures 1-8The copper wire straightening device for cable processing shown includes a base 1. Two wire-infeed driving wheels 2 are symmetrically arranged on one side of the upper end of the base 1, and two wire-pulling driving wheels 5 are symmetrically arranged on the other side of the upper end of the base 1. Multiple straightening wheels 4 are staggered and arranged in the middle of the upper end of the base 1. Copper wire is passed between the two wire-infeed driving wheels 2, and straightened by the push of the two wire-infeed driving wheels 2. The straightened copper wire is then passed between the two wire-pulling driving wheels 5 and sent out. The two wire-infeed driving wheels 2 and the two wire-pulling driving wheels 5 are all driven by motors to rotate in opposite directions to push the copper wire. Since the above-mentioned driving method and straightening process are existing technologies and widely used, they are not described in detail here. An adapter is provided at the front edge of the upper end of the base 1. Two fixing frames 16 are symmetrically connected to the adapter. A drive shaft 15 is rotatably mounted through the inner side of the end of the fixing frame 16, and the outer side of the end of the fixing frame 16... A brush holder 20 is rotatably mounted, and a fixed frame 16 supports the drive shaft 15 and the brush holder 20. A steel brush 19 is mounted on the lower end of the brush holder 20, and the brush holder 20 supports the steel brush 19. A drive shaft 28 is rotatably mounted on the side of the brush holder 20. The steel brush 19 can clean the wire grooves on the surface of the straightening wheel 4 to remove hard particles such as oxide scale from the straightening wheel 4, so as to avoid scratching the surface of the copper wire during straightening. The drive shaft 28 is connected to the steel brush 19 and the drive shaft 15 respectively. The drive shaft 28 serves as a transmission shaft, with a pawl 29 extending from its upper end. A trapezoidal frame 27 is rotatably mounted on the end of the pawl 29, and the end of the trapezoidal frame 27 is rotatably connected to one side of the fixed frame 16. The pawl 29 can continuously push the brush holder 20, causing the brush holder 20 to continuously swing in an arc around the drive shaft 15, thereby driving the steel brush 19 to continuously swing in an arc to clean the same position of the wire groove multiple times. An air blowing component is installed on the other side of the fixed frame 16.

[0030] The air blowing component includes an arc-shaped air shell 18 mounted on the other side of the fixed frame 16. A piston 25 is slidably mounted inside the arc-shaped air shell 18. An arc-shaped column 21 extends from the middle of the piston 25 and passes through one end of the arc-shaped air shell 18. The arc-shaped column 21 is slidably engaged with the arc-shaped air shell 18. The end of the arc-shaped column 21 is fixed to the brush holder 20. The arc-shaped column 21 serves to connect the piston 25 and the brush holder 20 together. When the brush holder 20 swings in an arc, it will also drive the arc-shaped column 21 to move, thereby driving the piston 25 to slide back and forth in the arc-shaped air shell 18, so as to continuously draw air into the arc-shaped air shell 18 and spray it out through the air nozzle 26.

[0031] Multiple air nozzles 26 are evenly distributed and fixedly connected to the edge of the arc-shaped air shell 18 relative to the end face of the straightening wheel 4. The air nozzles 26 are inclined and can blow the brushed hard particles in the opposite direction to the direction of the copper wire, so that they fall off, so as to avoid the brushed hard particles still adhering to the straightening wheel 4 and scratching the surface of the copper wire. A connecting frame 17 is fixedly installed in the middle of the arc-shaped air shell 18. The end of the connecting frame 17 is fixed to the fixing frame 16. The connecting frame 17 serves to fix the arc-shaped air shell 18.

[0032] The lower end face of the drive shaft 28 and the end of the brush shaft of the steel brush 19 are both coaxially inlaid with helical gears 31. The two helical gears 31 mesh with each other and serve to connect the drive shaft 28 and the steel brush 19 together. The lower end of the drive shaft 15 is coaxially inlaid with a large-diameter pulley 33, and the upper outer surface of the drive shaft 28 is coaxially inlaid with a small-diameter pulley 32. The small-diameter pulley 32 and the large-diameter pulley 33 serve to accelerate the transmission. A synchronous belt 30 is connected between the small-diameter pulley 32 and the large-diameter pulley 33. The synchronous belt 30 serves to connect the drive shaft 28 and the drive shaft 15 together.

[0033] The adapter includes an adjustment seat 3 fixedly installed at the upper front edge of the equipment base 1. A T-shaped carrier 9 is slidably installed inside the adjustment seat 3. The adjustment seat 3 serves to allow the T-shaped carrier 9 to slide. An extension bracket 10 extends from the upper end of the T-shaped carrier 9. A bolt 11 is screwed through the end of the extension bracket 10. The extension bracket 10 serves to support the bolt 11. The front end face of the adjustment seat 3 has multiple fixed wheel grooves 8. The distribution spacing of the multiple fixed wheel grooves 8 matches the distribution spacing between the feed power wheel 2, the straightening wheel 4, and the pulling power wheel 5. This ensures that when the bolt 11 is inserted into different fixed wheel grooves 8, the steel brush 19 and the arc-shaped air shell 18 can correspond to the feed power wheel 2, the straightening wheel 4, or the pulling power wheel 5. The end of the bolt 11 is inserted into the interior of one of the fixed wheel grooves 8.

[0034] A support frame 6 is fixedly installed on the upper end of the T-shaped carrier 9 near the side of the protruding frame 10. A separating threaded rod 22 is rotatably installed through the end of the support frame 6, and a guide rod 23 is embedded through the end of the support frame 6. The support frame 6 serves to support the separating threaded rod 22 and the guide rod 23. The guide rod 23 is located below the separating threaded rod 22 and serves to guide. The threads at both ends of the separating threaded rod 22 are symmetrically arranged, which can drive the separating seat 24 and the adapting seat 12 to move in opposite directions, so that the steel brush 19 and the arc-shaped air shell 18 are separated from the straightening wheel 4. When the steel brush 19 and the arc-shaped air shell 18 are adjusted to the left and right positions, they will not be obstructed by the straightening wheel 4. The separating seat 24 is screwed to one end of the separating threaded rod 22, and the adapting seat 12 is screwed to the other end of the separating threaded rod 22. Both the separating seat 24 and the adapting seat 12 are slidably installed on the outer surface of the guide rod 23.

[0035] An adapting threaded rod 13 is rotatably mounted inside the adapting seat 12. The adapting seat 12 can support the adapting threaded rod 13 and guide the adapting frame 14. The adapting frame 14 is screwed onto the outer surface of the adapting threaded rod 13. The adapting frame 14 is slidably mounted inside the adapting seat 12. The adapting threaded rod 13 drives the adapting frame 14 to move. A servo motor 7 is fixedly mounted on the upper end of the adapting frame 14 and the end of the separating seat 24. The output end of the servo motor 7 is fixed to the drive shaft 15. The servo motor 7 drives the drive shaft 15 to rotate. Two fixed frames 16 are fixed to the adapting frame 14 and the separating seat 24 respectively.

[0036] A method for using a copper wire straightening device for cable processing is also provided, including the following steps:

[0037] S1: Pass the copper wire between two input power wheels 2, so that the copper wire is straightened by passing between multiple straightening wheels 4 under the push of the two input power wheels 2. The straightened copper wire is then sent out by passing between two pulling power wheels 5.

[0038] S2: During this process, the steel brush 19 and the arc-shaped air shell 18 are moved to the infeed power wheel 2, the straightening wheel 4 or the pulling power wheel 5 using the adapter.

[0039] S3: Subsequently, the servo motor 7 drives the steel brush 19 and piston 25 to move synchronously to remove hard particles such as oxide scale on the wire feed wheel 2, straightening wheel 4 and wire pull wheel 5, so as to avoid scratching the surface of the copper wire.

[0040] During straightening, the copper wire is passed between two input power wheels 2. Driven by the two input power wheels 2, the copper wire passes between multiple straightening wheels 4 for straightening. The straightened copper wire then passes between two pull power wheels 5 and is fed out. During this process, the servo motor 7 drives the drive shaft 15 to rotate, which in turn drives the transmission shaft 28 to rotate. The transmission shaft 28 drives the steel brush 19 to rotate, cleaning the wire grooves on the surface of the straightening wheels 4. At the same time, the transmission shaft 28 also drives the claw 29 to rotate. At this time, the trapezoidal frame 27 moves... The brush holder 20 is moved to adapt to the rotation of the pawl 29, so that the pawl 29 continuously pushes the brush holder 20, causing the brush holder 20 to continuously oscillate in an arc around the drive shaft 15. This, in turn, drives the steel brush 19 to continuously oscillate in an arc, so as to clean the same position of the wire groove multiple times, thereby removing hard particles such as oxide scale from the straightening wheel 4 to avoid scratching the surface of the copper wire during straightening. At the same time, when the brush holder 20 oscillates in an arc, it also drives the arc-shaped column 21 to move, which in turn drives the piston 25 to slide back and forth in the arc-shaped air shell 18, so as to continuously draw in air. The arc-shaped air housing 18 is sprayed out through the air nozzle 26 to blow the brushed hard particles in the opposite direction to the copper wire, causing them to fall off. This prevents the brushed hard particles from adhering to the straightening wheel 4 and scratching the copper wire surface. When it is necessary to clean other straightening wheels 4, or the wire feeding power wheel 2 and the wire pulling power wheel 5, the separating threaded rod 22 can be rotated to drive the separating seat 24 and the adapting seat 12 to move in the opposite direction, allowing the steel brush 19 and the arc-shaped air housing 18 to disengage from the straightening wheel 4. Then, the bolt 11 can be unscrewed from the fixed wheel groove 8, allowing the T-shaped load to be released. The seat 9 slides within the adjusting seat 3 to adjust the position of the steel brush 19 and the arc-shaped air shell 18, moving them to the infeed power wheel 2, the pull power wheel 5, or another straightening wheel 4. Then, the adapting threaded rod 13 is rotated to drive the adapting frame 14 to move, which in turn drives the rear fixed frame 16 to move, so that the two fixed frames 16 can be in a staggered or aligned state, thereby adapting to the staggered straightening wheel 4 or the aligned infeed power wheel 2 and pull power wheel 5. Then, they can be cleaned to avoid scratching the surface of the copper wire during straightening.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
