[0013] The beneficial effects of the present invention:

[0014] 1. During the winding process of the left roller, when there is a bending point on the coil wire, this part of the coil wire moves into the heating coil body. The left roller and the right roller stop rotating. After the heating coil body finishes the on-line heating of this bending point, the left roller and the right roller rotate in opposite directions under the drive of their respective drive boxes. During this process, a tensile force is generated on the coil wire, thereby straightening the heated bending point. When this bending point is stretched and straightened, the left roller and the right roller rotate in the same direction again, winding the coil wire around the left roller, enabling the device to wind and collect the coil wire while stretching and straightening it, which is convenient to use.

[0015] 2. When the coil wire is first wound around the right roller for preliminary winding and collection, if there is rust on the coil wire, when it passes between the lower scraping groove and the upper scraping groove, the lower scraping blade and the upper scraping blade will scrape off the rust on the coil wire, ensuring the later use effect of the coil wire.

[0016] 3. When the left roller and the right roller cooperate to complete the stretching and straightening of the coil, when the coil wire passes through the wiping ring, the wiping ring wipes off the rust powder and some dust impurities scraped off from the outer wall of the coil wire. There is a protective oil smeared on the inner wall of the wiping ring near the end position. After the coil wire passes through the wiping ring, it can not only remove the rust powder and dust impurities, but also scrape off the protective oil, ensuring the later use effect of the coil wire; through the cooperation of the telescopic rod and the telescopic spring set, the lifting block and the wiping ring can move dynamically up and down following the winding diameter of the coil on the right roller and the left roller, enabling the wiping ring to always hold the outer wall of the coil wire, and also avoiding excessive friction between the wiping ring and the coil wire, which affects the service life of the wiping ring.

A heating coil mounting plate is fixed on the inner side wall of the workbench 1 and between the two pairs of roller supports 2. A heating coil body 5 is fixed at the bottom of the heating coil mounting plate. By setting the heating coil body 5, the coil wire that needs to be straightened is heated, which is convenient for stretching the bending point of the coil wire. Locking mechanisms are provided on both the left roller 3 and the right roller 4. A scraping mechanism is provided on the inner surface of the workbench 1 and on one side of the right roller 4. A wiping mechanism is provided on the inner surface of the workbench 1 and between the left roller 3 and the heating coil body 5. Two groups of drive boxes 6 that cooperate with the left roller 3 and the right roller 4 are movably arranged on the inner side wall of the workbench 1. When the right roller 4 winds the aluminum alloy coil wire to be stretched and straightened onto its side wall, one end of the coil wire is passed through the heating coil body 5 and then clamped and fixed to the wire groove 8 of the left roller 3. Then the left roller 3 rotates to wind the coil wire on the right roller 4 to the left roller 3. During this process, the heating coil body 5 is always in the standby state. When there is a bending point on the coil wire during the winding process of the left roller 3, this part of the coil wire moves into the heating coil body 5. The left roller 3 and the right roller 4 stop rotating. After the heating coil body 5 finishes on-line heating of this bending point, the left roller 3 and the right roller 4 rotate in opposite directions under the drive of their respective drive boxes 6. During this process, a tensile force is generated on the coil wire, so as to straighten the heated bending point. When this bending point is stretched and straightened, the left roller 3 and the right roller 4 rotate in the same direction again to wind the coil wire on the left roller 3.

[0026] Each locking mechanism includes side wall through holes 7 respectively opened on the side walls of the left roller 3 and the right roller 4. Wire grooves 8 are opened on the outer side walls of the left roller 3 and the right roller 4. Clamping grooves are opened on the outer side walls of the left roller 3 and the right roller 4. A rotating block 9 is rotatably arranged in the clamping groove. A resisting groove is opened on one side of the rotating block 9 close to the wire groove 8. A fixing component is provided on the side wall of each rotating block 9. Each fixing component includes a locking bolt 10 arranged on the side wall of the rotating block 9. The locking bolt 10 movably penetrates the rotating block 9, and the threaded end of the locking bolt 10 threadedly penetrates the clamping groove. When in use, the operator passes one end of the coil wire through the side wall through hole 7, then places the end of the coil wire into the wire groove 8, then flips and closes the rotating block 9 so that the coil wire is clamped in the resisting groove and the wire groove 8, and then the operator rotates the locking bolt 10 forward to lock and fix the rotating block 9, so that the rotating block 9 firmly resists against the outer side wall of the coil wire, and the operation is convenient.

[0027] The scraping mechanism includes two bottom wire feeding roller mounting frames 11 fixed on the inner surface of the workbench 1, each bottom wire feeding roller mounting frame 11 is rotatably provided with a bottom wire feeding large roller, the inner surface of the workbench 1 and the intermediate support seat 12 is fixed between the two bottom wire feeding roller mounting frames 11, the upper end surface of the intermediate support seat 12 is fixed with a lower mounting block 13, the side wall of the lower mounting block 13 is provided with a lower scraping groove, the inner wall of the lower scraping groove is fixed with a lower scraping blade 14, the upper end surface of the lower mounting block 13 is provided with an upper mounting block 15, the side wall of the upper mounting block 15 is provided with an upper scraping groove, the inner wall of the upper scraping groove is fixed with an upper scraping blade 16, the inner surface of the workbench 1 A wire feeding assembly is provided on the surface. When the coil wire to be processed is stretched and straightened, the end of the coil wire is first passed through the upper side wall of each bottom wire feeding roller, and passed between the lower scratching groove and the upper scratching groove, so that the bottom wire feeding roller can receive and guide the coil wire, and then the end of the coil wire is snap-fitted and fixed to the wire groove 8 on the right roller 4, and then the right roller 4 is rotated, and the coil wire is first wound onto the right roller 4. During this process, if there is rust stains on the coil wire, when it passes between the lower scratching groove and the upper scratching groove, the lower scratching blade 14 and the upper scratching blade 16 will scrape off the rust stains on the coil wire to ensure the later use effect of the coil wire.

[0028] Lower connecting plates 17 are fixed on both sides of the lower mounting block 13, and each lower connecting plate 17 is movably provided with a lower fixing bolt, and the threaded end of the lower fixing bolt is threadedly penetrated into the intermediate support seat 12. Two upper connecting plates 18 are symmetrically fixed on the side wall of the upper mounting block 15 located on the adjacent side of the lower connecting plate 17, and the upper end surface of the upper connecting plate 18 is movably provided with an upper fixing bolt, and the threaded end of the upper fixing bolt is threadedly penetrated into the lower mounting block 13. When the upper scratch blade 16 on the upper mounting block 15 or the lower scratch blade 14 on the lower mounting block 13 is damaged and needs to be replaced, the operator can loosen and disassemble each upper fixing bolt and lower fixing bolt accordingly, separate the upper mounting block 15 and the lower mounting block 13, replace the new upper scratch blade 16 or the lower scratch blade 14, and then install and reset the upper mounting block 15 and the lower mounting block 13, which is easy to operate.

[0029] The wire feeding assembly includes a lower stabilizing seat 19 fixedly arranged on the side wall of the bottom wire feeding roller mounting bracket 11. Two lower stabilizing rollers are symmetrically and rotatably arranged on the upper end face of the lower stabilizing seat 19. An upper fixing bracket 20 is fixed on the inner side wall of the workbench 1. An upper movable block 21 is movably arranged at the bottom of the upper fixing bracket 20. A longitudinal stabilizing fixing bracket 22 is fixed on one side of the bottom of the upper movable block 21. A longitudinal stabilizing roller body is rotatably arranged on the side wall of the longitudinal stabilizing fixing bracket 22. Another upper stabilizing seat 23 is fixed on the other side of the bottom of the upper movable block 21. Two upper stabilizing rollers are symmetrically and rotatably arranged at the bottom of the upper stabilizing seat 23. The coil wire passes through between the two lower stabilizing rollers, ensuring smoothness during the transmission and winding of the coil wire, and avoiding affecting the use effects of the upper scraping blade 16 and the lower scraping blade 14. The coil wire passes through between the two upper stabilizing rollers and is wound around the inner wall of the right roller 4 through the lower surface of the longitudinal stabilizing roller body. During the reciprocating movement of the upper movable block 21 back and forth, the coil wire is driven to move reciprocally, enabling the coil wire to be evenly wound around the inner side wall of the right roller 4.

[0030] The wiping mechanism includes a side fixing frame 24 fixed to the inner surface of the workbench 1. A guide rod 25 is fixed between the side fixing frame 24 and the inner wall of the workbench 1. A sliding block 26 is slidably penetrated through the guide rod 25. A lead screw 27 is rotatably arranged between the side fixing frame 24 and the inner wall of the workbench 1. A motor for driving the rotation of the lead screw 27 is arranged on the inner wall of the workbench 1. The lead screw 27 is threadedly penetrated through the sliding block 26. An expansion rod 28 is fixed to the bottom of the sliding block 26. One end of the expansion rod 28 away from the sliding block 26 is fixed with a lifting block 29. A telescopic spring is fixedly arranged between the lifting block 29 and the sliding block 26. The telescopic spring is movably sleeved on the outer side wall of the expansion rod 28. A wiping ring 30 is arranged on the lifting block 29. When all the coil wires after rust removal treatment are wound around the right roller 4, the movable end of the coil wire is wound through the heating coil body 5 and the wiping ring 30 and then fixed to the inner wall of the left roller 3. Then the left roller 3 rotates to cooperate with the right roller 4 to complete the stretching and straightening of the coil wire. During this process, the wiping ring 30 is held against the outer side wall of the coil wire. The inner wall of the wiping ring 30 contacts the outer side wall of the coil wire. When the coil wire passes through the wiping ring 30, the wiping ring 30 wipes off the rust powder and some dust impurities scraped off from the outer side wall of the coil wire. A protective oil is applied on the inner wall of the wiping ring 30 near the end position. After the coil wire passes through the wiping ring 30, it can not only remove rust powder and dust impurities, but also be rubbed with the protective oil to ensure the later use effect of the coil wire. During use, the sliding block 26 moves back and forth under the action of the lead screw 27, so that the coil on the right roller 4 can be evenly wound around the left roller 3. Through the cooperation of the expansion rod 28 and the telescopic spring, the lifting block 29 and the wiping ring 30 can move dynamically up and down following the winding diameters of the coils on the right roller 4 and the left roller 3, so that the wiping ring 30 can always be held against the outer side wall of the coil wire, and the friction force between the wiping ring 30 and the coil wire is also avoided from being too large, affecting the service life of the wiping ring 30.

[0031] An installation through hole 31 is opened on the side wall of the lifting block 29. A side contact ring 32 is fixed to the inner wall of the installation through hole 31 to prevent the wiping ring 30 from falling off from the installation through hole 31 during use and affecting the use effect. A clamping gap is opened on the side wall of the wiping ring 30. Plug blocks 33 are symmetrically fixed on both sides of the wiping ring 30. Slots for cooperating with the plug blocks 33 are symmetrically opened on the inner side wall of the installation through hole 31. When the wiping ring 30 needs to be replaced, it can be removed from the coil wire through the clamping gap, and a new wiping ring 30 is replaced. Then it is placed into the installation through hole 31 of the lifting block 29. Through the arranged installation through hole 31, the wiping ring 30 is resisted to make the wiping ring 30 completely hold against the outer side wall of the coil wire without gaps. Through the cooperation of the plug blocks 33 and the slots, the wiping ring 30 is limited and fixed, so that the wiping ring 30 can be clamped and fixed in the installation through hole 31, which is convenient to use.

[0032] When the present invention is in use, firstly, the end of the coil wire is passed through the upper end side wall of each bottom wire feeding roller, and passes through between the lower scraping groove and the upper scraping groove, so that the bottom wire feeding roller can receive and guide the coil wire, and then the end of the coil wire is clamped and fixed to the wire groove 8 on the right roller 4, and then the right roller 4 rotates, and the coil wire is first wound onto the right roller 4. In this process, if there is rust stain on the coil wire, when it passes between the lower scraping groove and the upper scraping groove, the lower scraping blade 14 and the upper scraping blade 16 will scrape off the rust stain on the coil wire, so as to ensure the later use effect of the coil wire;

[0033] When all the coil wires that have been derusted are wound onto the right roller 4, the movable end of the coil wire is wound through the heating coil body 5 and the wiping ring 30 and then fixed to the inner wall of the left roller 3. Then the left roller 3 rotates and cooperates with the right roller 4 to complete the stretching and straightening of the coil wire. During this process, the wiping ring 30 embraces the outer wall of the coil wire, and the inner wall of the wiping ring 30 contacts the outer wall of the coil wire. When the coil wire passes through the wiping ring 30, the wiping ring 30 wipes the rust stains, powder and some dust impurities scraped off the outer wall of the coil wire. Protective oil is applied on the inner wall of the wiping ring 30 and near the end. After the coil wire passes through the wiping ring 30, not only It can remove rust stains, powder and dust impurities, and can also remove the protective oil that is scratched, so as to ensure the later use effect of the coil wire. During use, the sliding block 26 moves back and forth under the action of the screw rod 27, so that the coil on the right roller 4 can be evenly wound on the left roller 3. Through the cooperation of the telescopic rod 28 and the telescopic spring, the lifting block 29 and the wiping ring 30 can move up and down dynamically following the winding diameter of the coil on the right roller 4 and the left roller 3, so that the wiping ring 30 can always be engaged with the outer wall of the coil wire, and it also avoids excessive friction between the wiping ring 30 and the coil wire, which affects the service life of the wiping ring 30.

[0034] After the right roller 4 winds the aluminum alloy coil wire to be stretched and straightened onto its side wall, one end of the coil wire is passed through the heating coil body 5 and then clamped and fixed to the wire groove 8 of the left roller 3. Then, the left roller 3 rotates to wind and transfer the coil wire on the right roller 4 to the left roller 3. During this process, the heating coil body 5 is always in the standby state. When there is a bending point on the coil wire during the winding process of the left roller 3, this part of the coil wire moves into the heating coil body 5. The left roller 3 and the right roller 4 stop rotating. After the heating coil body 5 finishes the on-line heating of this bending point, the left roller 3 and the right roller 4 rotate in opposite directions under the drive of their respective drive boxes 6. During this process, a tensile force is generated on the coil wire, so as to straighten the heated bending point. When the bending point is stretched and straightened, the left roller 3 and the right roller 4 rotate in the same direction again to wind the coil wire around the left roller 3.

[0035] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.

After the heating coil body (5) finishes online heating of this bending point, the left roller (3) and the right roller (4) rotate in opposite directions under the drive of their respective drive boxes (6). During this process, a tensile force is generated on the coil wire, so as to straighten the heated bending point. When this bending point is stretched and straightened, the left roller (3) and the right roller (4) rotate in the same direction again to wind the coil wire on the left roller (3).
