Description

Technical Field

[0001] This invention relates to the field of rolling mill technology, specifically to a rolling process for inner flat copper bodies of enameled electromagnetic wire. Background Technology

[0002] The conductors in enameled electromagnetic wire are usually made of copper. The copper needs to be processed into flat copper bodies for use. The flat copper bodies are formed by rolling copper wire. The rolling of copper wire generally requires multiple sets of rollers to roll it into shape. When the copper wire is rolled multiple times, the lateral deformation of the first roll is often the largest, which leads to uneven deformation. Existing rolling mills cannot control the initial deformation of copper wire during rolling, resulting in uneven width and affecting the rolling quality. Furthermore, the surface of the copper wire needs to be cleaned before rolling to reduce the occurrence of surface defects. However, cleaning is often done manually, which makes the workload of workers heavy and the cleaning efficiency low. Summary of the Invention

[0016] Preferably, the width limiting component is a movable support bar, on which a width limiting bar is fixedly installed to limit the lateral deformation of the copper wire.

[0017] Preferably, two assembly strips are symmetrically fixed on the rolling mill, and there are two movable support strips, which are respectively installed on the two assembly strips.

[0018] Preferably, the copper wire cleaning assembly includes: two cleaning support plates, which are movably mounted on the assembly support;

[0024] The toothed block is movably mounted on the mounting strip.

[0025] Preferably, the toothed block meshes with the gear, driving the gear to rotate, thereby enabling the replacement of the supporting arc plate.

[0026] Preferably, the replacement adjustment component further includes a movable positioning plate, which locks the tooth block.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] This invention provides a technical solution:

[0046] A rolling process for the inner flat copper body of enameled electromagnetic wire includes the following steps:

[0047] Step 1: Raw material preparation: Prepare the copper wire raw materials;

[0048] Step 2: Heat treatment of raw materials: Heat treatment is performed on the copper wire raw materials to improve the plasticity of the copper wire;

[0049] Step 3: Pickling of raw materials: Pickling the copper wire raw materials to improve the surface quality of the copper wire;

[0050] Step 4: Copper wire rolling: The copper wire is rolled multiple times using rolling mill 1 to form a flat copper body;

[0051] Step 5: Surface treatment of flat copper body: Polish the rolled flat copper body to ensure its surface quality.

[0052] like Figure 1 and Figure 2 As shown, multiple sets of rolling frames 11 are fixedly installed on the rolling mill 1 by screws, and the number of rolling frames 11 can be set according to the actual rolling requirements. Rollers 12 are installed on the rolling frames 11, and there are two rollers 12 on each rolling frame 11, which are arranged symmetrically above and below. The copper wire is rolled by the rollers 12. A drive assembly is installed at one end of the rolling mill 1. The drive assembly works with a width limiting assembly. When the copper wire is rolled for the first time, the width limiting assembly limits its rolling width. That is, the width limiting assembly is partially inserted between the two rollers 12 that roll the copper wire for the first time, and contacts the copper wire rolled for the first time to limit it. The drive assembly is also movably connected to a copper wire cleaning assembly. The copper wire cleaning assembly cleans the copper wire before it is rolled, avoiding the trouble of manual cleaning of the copper wire, and also improving the efficiency of copper wire cleaning.

[0053] like Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly includes a drive screw 2 and a drive strip 22. An assembly bracket 15 is welded and fixed at one end of the rolling mill 1. The drive screw 2 is mounted on the assembly bracket 15. Specifically, a threaded through hole 16 is provided on the assembly bracket 15. The threaded through hole 16 is threadedly engaged with the drive screw 2. A support guide hole 17 is also provided at the lower end of the assembly bracket 15. A support assembly rod 18 is welded and fixed on the assembly bracket 15.

[0054] The drive bar plate 22 is sleeved on the drive screw 2. Two limiting ring plates 21 are welded and fixed on the drive screw 2. The surface of the limiting ring plates 21 is smooth and burr-free. The drive bar plate 22 is located between the two limiting ring plates 21 and is in contact with the limiting ring plates 21. When the drive screw 2 rotates, it moves under the action of the thread. At the same time, under the action of the limiting ring plates 21, the drive bar plate 22 moves synchronously with the drive screw 2.

[0055] like Figure 1 and Figure 4As shown, the width limiting component is a movable support bar 4. A support rod 42 is welded and fixedly installed on the upper end of the movable support bar 4. A width limiting bar 44 is welded and fixed on the support rod 42 at the end away from the movable support bar 4. The width limiting bar 44 is inserted between the two rollers 12 that perform the initial rolling of the copper wire. The lateral deformation of the copper wire is limited by the width limiting bar 44.

[0056] Two assembly plates 13 are symmetrically welded and fixed on the rolling mill 1. Assembly movable holes 14 are opened on the assembly plates 13. There are two movable support bars 4, which are respectively installed on the two assembly plates 13. Specifically, the support rods 42 on the movable support bars 4 are inserted into the assembly movable holes 14, and a first spring 43 is sleeved on the support rods 42. The two ends of the first spring 43 are welded and fixed to the movable support bars 4 and the assembly plates 13 respectively. In addition, the width limiting strips 44 on the two movable support bars 4 limit the width of the copper wire from both sides.

[0057] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the movable support bar 4 is moved by the drive bar plate 22. Specifically, a matching guide rod 28 is welded and fixed to the lower end of the drive bar plate 22. The matching guide rod 28 is inserted into the support guide hole 17, and a drive matching bar 281 is welded and fixed to the end of the matching guide rod 28 away from the drive bar plate 22. Two push plates 282 are integrally formed on the drive matching bar 281. A push inclined surface 283 is provided on the push plate 282. The surface of the push inclined surface 283 is smooth and burr-free. A first contact block 41 is integrally formed at the lower end of the movable support bar 4. The surface of the first contact block 41 is smooth and burr-free. The push inclined surface 283 contacts the first contact block 41. Under the action of the push inclined surface 283, the movable support bar 4 is pushed to move. This causes the two width limiting bars 44 to move towards each other, which can limit the lateral deformation of the copper wire.

[0058] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the copper wire cleaning assembly includes two cleaning support plates 3 and a gear 6. The cleaning support plates 3 are movably mounted on the assembly support frame 15. There are two cleaning support plates 3, which are located on the upper and lower sides of the copper wire respectively. A guide hole 32 is provided at one end of the cleaning support plate 3, and a support assembly rod 18 is inserted into the guide hole 32.

[0059] Gear 6 is mounted on cleaning support plate 3. A support shaft 61 is welded and fixed on gear 6. A second magnet 62 is circumferentially embedded in the support shaft 61. A mounting through hole 36 is opened on cleaning support plate 3. A bearing 67 is installed in the mounting through hole 36. The bearing 67 cooperates with the support shaft 61. A mating block 34 is welded and fixed on cleaning support plate 3 next to the mounting through hole 36. A first magnet 35 is embedded in the mating block 34. The first magnet 35 and the second magnet 62 attract each other to position gear 6.

[0060] One end of the cleaning support plate 3 is welded and fixed with a connecting plate frame 31. A connecting rod 29 is hinged on the connecting plate frame 31. The other end of the connecting rod 29 is hinged to the drive bar plate 22. In this way, when the drive bar plate 22 moves, it can drive the two cleaning support plates 3 to move towards each other or away from each other.

[0061] A connecting bearing block 63 is welded and fixed to the lower end of the support shaft 61. A connecting bearing rod 64 is welded and fixed to the circumference of the connecting bearing block 63. There are four connecting bearing rods 64, which are evenly distributed on the connecting bearing block 63. A protruding connecting block 65 is welded and fixed to the end of the connecting bearing rod 64 away from the connecting bearing block 63. A supporting arc plate 66 is integrally formed on the protruding connecting block 65. The surface of the supporting arc plate 66 is smooth and burr-free.

[0062] A wiping block 68 is sleeved on the supporting arc plate 66, such as Figure 11 As shown, each end of the wiping block 68 is integrally formed with a mating protrusion 69. The mating protrusion 69 has a support ring groove 691. The wiping block 68 is fixed on the support arc plate 66 by the cooperation of the support ring groove 691 and the support arc plate 66. The copper wire is cleaned by the wiping block 68. Specifically, during cleaning, the wiping blocks 68 on the upper and lower sides of the copper wire close together as the support arc plate 66 moves, so that the two wiping blocks 68 come into contact with the copper wire. In this way, the copper wire can be wiped and cleaned by the action of the wiping blocks 68 when it moves, removing impurities and oil stains from the surface.

[0063] like Figure 5 , Figure 8 and Figure 10As shown, a replacement adjustment assembly is symmetrically installed on one of the movable support bars 4. The replacement adjustment assembly includes: a mounting support bar 5 and a toothed block 57. The mounting support bar 5 is connected to the cleaning support plate 3, and moves up and down by the cleaning support plate 3. Specifically, a second linkage insertion hole 37 is provided at the end of the cleaning support plate 3 away from the connecting plate frame 31. A support assembly plate 45 is integrally formed on one of the movable support bars 4. Assembly support rods 46 are symmetrically welded and fixed at the end of the support assembly plate 45 away from the movable support bar 4. A mating through hole 51 is provided on the mounting support bar 5, which mates with the assembly support rod 46. A support rod frame 52 is integrally formed on the mounting support bar 5 next to the mating through hole 51. A second linkage support rod 53 is welded and fixed on the support rod frame 52. The second linkage support rod 53 is inserted into the second linkage insertion hole 37. In this way, when the cleaning support plate 3 moves up and down, it can drive the mounting support bar 5 to move up and down along the assembly support rod 46.

[0064] The toothed block 57 is movably mounted on the mounting support strip 5. Specifically, an insertion through hole 54 is provided at the end of the mounting support strip 5 away from the mating through hole 51. A support rod 573 is welded and fixed to the toothed block 57. The support rod 573 is inserted into the insertion through hole 54, and a mating support plate 574 is welded and fixed to the end of the support rod 573 away from the toothed block 57. A second contact block 576 is integrally formed on the mating support plate 574. The surface of the second contact block 576 is smooth and burr-free. In addition, a second spring 575 is sleeved on the support rod 573. The two ends of the second spring 575 are welded and fixed to the mating support plate 574 and the mounting support strip 5, respectively. The second spring 575 can not only keep the position of the toothed block 57 stable, but also drive the toothed block 57 to move.

[0065] The toothed block 57 meshes with the gear 6, driving the gear 6 to rotate. That is, when the movable support bar 4 of the mounting support bar 5 moves, it will drive the mounting support bar 5 to move synchronously. As the mounting support bar 5 moves, it will also drive the toothed block 57 to move synchronously. In this way, the gear 6 can be driven to rotate under the action of the toothed block 57, thereby realizing the replacement of the support arc plate 66. That is, when the wiping block 68 is used to a certain extent and can no longer meet the cleaning needs, it can be replaced by rotating the support arc plate 66, so that the new wiping block 68 can rotate to the upper and lower sides of the copper wire to wipe and clean the copper wire.

[0066] like Figure 9 and Figure 10As shown, the replacement adjustment assembly also includes a movable positioning plate 58. A mating upright plate 55 is integrally formed on the end of the mounting support bar 5 away from the movable support bar 4. A movable through hole 56 is opened on the mating upright plate 55. A positioning rod 581 is welded and fixed on the movable positioning plate 58. The positioning rod 581 is inserted into the movable through hole 56, and a third spring 582 is sleeved on the positioning rod 581. The two ends of the third spring 582 are welded and fixed on the mating upright plate 55 and the movable positioning plate 58, respectively. The movable positioning plate 58 can be reset by the third spring 582. A mating block 572 is integrally formed on the toothed block 57 on the upper side of the positioning hole 571. When the positioning rod 581 contacts the mating block 572, the third spring 582 is in a stretched state. When the toothed block 57 is locked by the movable positioning plate 58, the positioning rod 581 is inserted into the positioning hole 571.

[0067] like Figure 5 and Figure 8 As shown, a support plate frame 38 is welded and fixed at one end of the cleaning support plate 3, and a limit stop bar 39 is welded and fixed on the support plate frame 38. The limit stop bar 39 can cooperate with the movable positioning plate 58, so that the positioning rod 581 inserted in the positioning socket 571 is removed from the positioning socket 571, thereby unlocking the tooth block 57.

[0068] like Figure 3 , Figure 4 and Figure 7 As shown, protruding support blocks 23 are integrally formed at both the upper and lower ends of the drive plate 22. An assembly guide rod 24 is welded and fixed between the two protruding support blocks 23. Movable bars 25 are sleeved on the assembly guide rod 24. Two movable bars 25 are symmetrically arranged on the assembly guide rod 24 and can move up and down along it. A first linkage insertion hole 26 is provided on the movable bar 25. A first linkage support rod 33 is welded and fixed to the cleaning support plate 3 and inserted into the first linkage insertion hole 26. When the cleaning support plate 3 moves up and down, it drives the movable bars 25 to move up and down as well. An inclined push block 27 is integrally formed on the movable strip 25. The surface of the inclined push block 27 is smooth and burr-free. When the drive strip 22 moves, it can also drive the movable strip 25 to move synchronously. When the drive strip 22 moves towards the assembly support 15, the inclined push block 27 will contact the second contact block 576 on the tooth block 57. In this way, under the action of the movable strip 25, the tooth block 57 can be pushed to move, so that the tooth block 57 separates from the gear 6. Thus, when the movable support 4 drives the tooth block 57 to move in the opposite direction, the tooth block 57 will not mesh with the gear 6, and therefore will not drive the gear 6 to rotate.

[0069] During the rolling of copper wire, the rotating drive screw 2 moves under the action of the thread. As the drive screw 2 moves, it also drives the drive plate 22 to move synchronously, causing the drive plate 22 to move towards the assembly support 15. As the drive plate 22 moves, the pushing inclined surface 283 comes into contact with the first contact block 41 on the movable support 4. Under the action of the pushing inclined surface 283, the two movable support 4s are pushed to move towards each other, which in turn drives the two width limiting strips 44 to move towards each other. In this way, when rolling copper wire, the lateral deformation of the copper wire can be limited by the action of the two width limiting strips 44, ensuring that the lateral deformation of each part is uniform. In addition, the drive plate 22 moves towards the assembly support. When the device moves in the direction of 15, the two cleaning support plates 3 will move towards each other under the action of the connecting rod 29. This allows the two wiping blocks 68 located on the upper and lower sides of the copper wire to close together and engage with the copper wire. As the copper wire moves, it can be wiped and cleaned by the wiping blocks 68. The movement of the cleaning support plate 3, in cooperation with the first linkage socket 26 and the first linkage support rod 33, will drive the movable strip 25 to move up and down synchronously. In cooperation with the second linkage socket 37 and the second linkage support rod 53, it will drive the mounting support strip 5 to move up and down synchronously. When the two movable support strips 4 move towards each other, since the toothed block 57 is meshing with the gear 6, the toothed block 57 will drive the gear 6 to rotate. Until the first contact block 41 passes the pushing inclined surface 283, the movable support bar 4 will no longer move. As the drive bar 22 continues to move, it will drive the inclined push block 27 on the movable bar 25 to contact the second contact block 576. Thus, as the movable bar 25 moves, the inclined push block 27 will push the second contact block 576 to move, thereby driving the toothed block 57 to move, causing the toothed block 57 to separate from the gear 6. Until the toothed block 57 moves to the positioning socket 571 and aligns with the positioning rod 581, the positioning rod 581 is inserted into the positioning socket 571 under the action of the third spring 582, locking the toothed block 57. This ensures that when the movable support bar 4 drives the toothed block 57 to move in the opposite direction, the toothed block 57 will not contact the gear 6. When the gear 6 is engaged, it will not rotate. During the reverse movement of the toothed block 57, the limiting stop 39 will contact the movable positioning plate 58, thus restricting its movement. As the mounting support 5 moves, the positioning insert 581 will disengage from the positioning socket 571, the third spring 582 will be stretched, and the toothed block 57 will reset under the action of the second spring 575, allowing it to re-engage with the gear 6. When the movable support 4 moves towards the gear 6 again, it can rotate the gear 6. The mutual attraction between the first magnet 35 and the second magnet 62 can position the rotated gear 6, maintaining its stability.When the wiping block 68 cannot meet the wiping requirements during the copper wire rolling process, the drive screw 2 can be rotated in the opposite direction, causing the drive plate 22 to move in the opposite direction. Under the action of the first spring 43, the movable support bar 4 will move in the opposite direction, which in turn will cause the mounting support bar 5 to move in the opposite direction. With the action of the connecting rod 29, the two cleaning support plates 3 will move in opposite directions, causing the wiping block 68 to separate. Then, when the drive screw 2 is rotated again to move the drive plate 22 towards the assembly support 15, the gear 6 will rotate under the action of the toothed block 57, thus realizing the switching of the wiping block 68. This is very convenient and simple to operate. Furthermore, the wiping block 68 is fitted onto the support arc plate 66 through the support ring groove 691, making it easy to install and remove, and thus convenient to replace the wiping block 68.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
