Description

Technical Field

[0001] The present application relates to the technical field of transformer core production, and in particular to a high-speed shear-to-length line. Background Art

[0002] The transformer core, the primary magnetic circuit component of a transformer, is typically constructed from stacked hot-rolled or cold-rolled silicon steel sheets with a high silicon content and a surface coating of insulating varnish. The silicon steel sheet shearing system is used to shear the complete silicon steel strip into sheets of defined shapes to facilitate subsequent assembly of the transformer core.

[0003] In the related art, a cross-cutting line for cutting yoke-shaped silicon steel sheets includes a frame, a cross-cutting device installed on the frame, and a conveying device. Support rails for supporting silicon steel bars are installed on both sides of the frame in the width direction; the cross-cutting device includes a punching component, a cutting component, and a V-punching component installed on the frame along the length direction of the frame to shear the silicon steel bars; the conveying device includes two sets of clamping wheels for clamping the silicon steel bars and a motor for driving the clamping wheels to rotate, so as to drive the silicon steel bars to move along the length direction of the frame. In addition, a moving device is also installed on the frame, and the moving device includes a motor-driven screw and a slider to drive the V-punching component to move along the length and width directions of the frame, so as to adjust the cutting direction of the silicon steel sheet by the V-punching component, thereby obtaining yoke-shaped silicon steel sheets of different specifications and sizes.

[0004] With respect to the above-mentioned related technologies, the inventors found that: when adjusting the position of the V-punch component, the support rail supporting the silicon steel bar also needs to be adjusted accordingly; usually, the support rails of different lengths are replaced to reduce the impact of the support rails on the moving V-punch component; and the above operation requires the preparation of support rails of different lengths, and the cross-cutting line needs to be stopped to cooperate with the workers to replace the support rails, which is very inconvenient and easily affects the shearing efficiency of the silicon steel sheet, so it needs to be improved. Summary of the Invention

[0005] In order to reduce the interference between the position adjustment of the V-punch component and the support track, the present application provides a high-speed cross-cutting line.

[0006] The high-speed shear-to-length line provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, the entire support rail is divided into several groups of support plates, and the support plates can be moved by a moving mechanism, so as to flexibly adjust the position and length of the support rail to match the cutting device; when the cutting device needs to be displaced, the moving mechanism is controlled to make the support plates that will interfere with the cutting device move away from the silicon steel bars, so that the support plates give way to the displacement of the cutting device, thereby reducing the interference between the position adjustment of the cutting device and the support rail.

[0009] Preferably, the moving mechanism is provided in several groups along the length direction of the frame, the moving mechanism is a moving cylinder, the moving mechanism and the support plate are provided in one-to-one correspondence, and each support plate is provided at the output end of the corresponding moving mechanism.

[0010] By adopting the above technical solution, each moving mechanism operates independently of each other. During the movement of the cutting device, the output end of a part of the moving mechanism is controlled to retract, so that the support plate is away from the cutting device and the silicon steel bar, and makes way for the displacement of the cutting device; the output end of the other part of the moving mechanism is kept in an extended state, so that the support plate that does not interfere with the cutting device supports the silicon steel bar, thereby reducing the interference between the position adjustment of the cutting device and the support track.

[0011] Preferably, each of the moving mechanisms is tiltedly arranged on the fixed frame.

[0012] By adopting the above technical solution, the inclined moving mechanism can further reduce the installation space required for the moving mechanism; the inclined moving mechanism can drive the support plate to move along the vertical direction and the width direction of the frame, providing more space for the displacement of the cutting device, so as to facilitate the position adjustment of the cutting device.

[0013] Preferably, the fixed frame is provided with several groups of guide rails along the length direction of the frame, and a sliding block is slidably provided on each of the guide rails, the guide rails, sliding blocks, support plates and moving mechanisms are respectively provided in one-to-one correspondence, each of the support plates is provided on the side wall of the sliding block facing the silicon steel bar, and the output end of each of the moving mechanisms is connected to the corresponding sliding block.

[0014] By adopting the above technical solution, the rigidity of the piston rod of the mobile cylinder is taken into consideration and it is easy to break; by setting the guide rail and the sliding block to connect the support plate, the phenomenon of the mobile cylinder piston rod breaking is reduced.

[0015] Preferably, the support plate is rotatably connected to the fixed frame, and the moving mechanism includes several groups of fixed tubes, several groups of support rods, a driving assembly, a moving assembly, a reset assembly and a locking assembly; the fixed tubes, support rods and support plates are respectively arranged in one-to-one correspondence, all of the fixed tubes are arranged on the fixed frame, each of the support rods is slidably arranged on the corresponding fixed tube, and each of the support rods can be abutted against the lower surface of the corresponding support plate; the driving assembly is arranged on the fixed frame to drive the support rod close to the support plate; the reset assembly is arranged on each group of support rods to drive the corresponding support rod to reset; the moving assembly is arranged on the fixed frame to drive the driving assembly to move along the length direction of the frame; the locking assembly is arranged on each group of support rods to limit the corresponding support rod from sliding.

[0016] By adopting the above technical solution, the moving assembly controls the driving assembly to move along the length direction of the frame, so as to drive the support rod inside any fixed tube, so that the support rod gradually approaches the support plate and supports the support plate, so that the support plate rotates toward the direction close to the silicon steel bar, so that the support plate supports the silicon steel bar;

[0017] When the support rod is separated from the support plate, the support plate rotates in the direction away from the silicon steel bar under the influence of its own gravity, so as to make way for the displacement of the cutting device, thereby reducing the interference between the position adjustment of the cutting device and the support rail;

[0018] By arranging the fixing tube, the support rod, the moving assembly, the driving assembly, the resetting assembly and the locking assembly, the purpose of moving all the support plates is achieved, which reduces the need to configure driving facilities for each group of support plates, thereby reducing production costs;

[0019] When the driving assembly is disengaged from driving the support rod, the reset assembly can drive the support rod to quickly reset, so that the support rod can be disengaged from supporting the support plate, thereby facilitating the support plate to rotate in a direction away from the silicon steel bar, thereby achieving the reset of the support plate by its own weight;

[0020] When the driving assembly is disengaged from the drive of the support rod, the locking assembly can limit the movement of the support rod, so that the support rod maintains its supporting effect on the support plate, so that the support plate can continue to provide auxiliary support for the silicon steel bar; when the support plate needs to be reset, the restriction of the locking assembly on the support rod can be released, and the reset assembly can be used to drive the support rod to quickly reset, thereby conveniently realizing the reset of the support plate.

[0022] By adopting the above technical solution, the output end of the drive motor drives the drive gear to rotate, and the rotating drive gear engages with the transmission rack, so that the transmission rack drives the drive rod to approach and push the support rod toward the direction close to the support plate, or drives the drive rod away from the support rod.

[0023] Preferably, the reset assembly includes a fixed block and a reset member; the fixed block is arranged on the side wall of each group of support rods, and a sliding groove for the fixed tube to slide is provided on the inner side wall of each fixed tube, and the reset member is arranged inside the sliding groove, one end of the reset member is abutted against the inner side wall of the sliding groove, and the other end of the reset member is connected to the fixed block to drive the fixed block to move toward the direction close to the driving assembly.

[0024] By adopting the above technical solution, when the driving component drives the support rod to move toward the direction close to the support plate, the support rod drives the fixed block to gradually approach the support plate and press the reset member, causing the reset member to deform and contract and accumulate elastic potential energy; when the driving component disengages from the drive of the support rod and the locking component cancels the limit on the support rod, the reset member can drive the fixed block to drive the support rod to move in the direction away from the support plate through its own elastic force, so that the support rod and the support plate are reset.

[0025] Preferably, the moving assembly includes a moving screw, a moving guide rod, a moving block and a moving motor; the moving screw is rotatably set on a fixed frame, the moving guide rod is set on the fixed frame, and the length directions of the moving screw and the moving guide rod are parallel to the length direction of the frame; the moving block is sleeved on the moving screw and the moving guide rod, the moving block is threadedly connected to the moving screw, and the driving tube is set on the moving block; the moving motor is set on the fixed frame to drive the moving screw to rotate.

[0026] By adopting the above technical solution, the output end of the mobile motor drives the mobile screw to rotate, the rotating mobile screw and the mobile block are threadedly transmitted, and the mobile guide rod guides the mobile block, thereby driving the mobile block to drive the driving tube to move along the length direction of the frame; after the driving tube and any fixed tube are aligned with each other, the driving assembly can drive the support rod inside the fixed tube.

[0027] Preferably, the locking assembly includes a rotating platform, a locking rod, a clamping edge block, a rotating platform and a rotating motor; the rotating platform is rotatably arranged on the end wall of each group of support rods facing the driving rod, and the locking rod is arranged on the peripheral wall of the rotating platform; each of the fixed tubes is provided with a sliding opening for sliding the driving rod along the sliding direction of the support rod, and each of the fixed tubes is provided with a locking notch connected to the sliding opening, so that the locking rod can be rotated and pressed into;

[0028] The rotating platform is rotatably arranged at the end of each group of driving rods facing the support rod, the clamping edge block is arranged on the side wall of each group of rotating platforms facing the support rod, and each of the rotating platforms is provided with a clamping groove for the clamping edge block to be inserted into; the rotating motor is arranged on each group of driving rods to drive the corresponding rotating platform to rotate.

[0029] By adopting the above technical solution, when the driving rod gradually approaches the support rod, the engaging edge block can gradually press into the engaging groove; the driving rod drives the support rod gradually close to the support plate, and the support rod drives the locking rod to move inside the sliding opening, and gradually moves to the connection point between the sliding opening and the locking notch; the output end of the rotating motor is rotated forward to drive the rotating table, the engaging edge block and the rotating table to rotate forward, so that the locking rod can be rotated and press into the locking notch, thereby limiting the sliding of the support rod relative to the fixed tube, ensuring that the support rod stably supports the support plate when the driving assembly is out of the driving state of the support rod;

[0030] When the output end of the rotating motor is driven to reverse, the rotating table, the clamping edge block and the rotating table rotate in the opposite direction, and the locking rod rotates out of the locking notch and rotates into the inside of the sliding opening; at this time, the driving rod can be driven to gradually disengage from the push on the support rod, and the support rod can be driven gradually away from the support plate through the reset component, thereby realizing automatic reset of the support rod and the support plate.

[0031] Preferably, each side wall of the locking notch facing away from the driving rod is provided with a limiting notch for the locking rod to slide into.

[0032] By adopting the above technical solution, when the driving rod gradually disengages from the push on the support rod and the locking rod is located in the locking notch, the reset assembly applies a force to the support rod to reset it away from the support plate, and the locking rod can be pushed into the limiting notch, thereby reducing the vibration of the support plate or the support rod, which causes the locking rod to disengage from the locking notch, thereby ensuring the stability of the locking assembly in limiting the support rod.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By dividing the entire support track into several groups of support plates and using a moving mechanism to move the support plates, the position and length of the support track that matches the cutting device can be flexibly adjusted. By controlling the moving mechanism to move the support plates, the support plates give way to the displacement of the cutting device, thereby reducing the interference between the position adjustment of the cutting device and the support track.

[0035] 2. By setting up a moving assembly to control the driving assembly to move along the length direction of the frame, it is convenient to drive the support rod inside any fixed tube, so that the support rod supports the support plate, and the support plate supports the silicon steel bar; when the support rod stops supporting the support plate, the support plate can reset itself, reducing interference with the cutting device;

[0036] 3. By setting up a locking assembly, the support rod can be restricted from moving, so that the support rod maintains its supporting effect on the support plate; in addition, the support plate can be easily reset by releasing the restriction of the locking assembly on the support rod and using the reset assembly to drive the support rod to quickly reset.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-7 This application is described in further detail.

[0047] The embodiment of the present application discloses a high-speed shear-to-length line for reducing the interference between the position adjustment of a V-punch component and a support track.

[0048] Example 1:

[0049] Reference Figure 1 A high-speed shear-to-length line includes a frame 1 and a cutting device 11 mounted on the frame 1. In this embodiment, the cutting device 11 can be a V-punch component. Support rails 2 are installed on both sides of the width direction of the frame 1 to support the silicon steel bar 10. The support rails 2 include a fixing frame 21 and a plurality of support plates 22. The fixing frame 21 is welded to the frame 1. The length direction of the fixing frame 21 is parallel to the length direction of the frame 1, and the cutting device 11 is located between the two sets of fixing frames 21.

[0050] Reference Figure 1A moving mechanism 3 is installed on the frame 1. In this embodiment, the moving mechanism 3 can be a moving cylinder. Multiple groups of moving mechanisms 3 are installed at intervals along the length of the fixed frame 21. Each group of moving mechanisms 3 is fixedly connected to the fixed frame 21, and the output ends of the moving mechanisms 3 on both sides of the frame 1 are all facing the silicon steel bars 10 on the frame 1. Each group of moving mechanisms 3 is located in the same horizontal plane, and the extension and contraction directions of the output ends of each group of moving mechanisms 3 are parallel to each other. The moving mechanisms 3 are respectively arranged in a one-to-one correspondence with the support plates 22. Each group of support plates 22 is fixedly connected to the output end of the corresponding moving mechanism 3 to drive the corresponding support plate 22 towards or away from the silicon steel bar 10.

[0051] The implementation principle of a high-speed shear-to-length line in Example 1 of the present application is as follows:

[0052] First, the output ends of all the moving mechanisms 3 are kept in a retracted state, so that each group of support plates 22 is in a state away from the cutting device 11, making room for the position adjustment of the cutting device 11; after the position adjustment of the cutting device 11 is completed, the output ends of the control part of the moving mechanisms 3 are extended, so that the support plates 22 that do not interfere with the cutting device 11 gradually move toward the direction close to the middle of the frame 1, so as to support the silicon steel bars 10, thereby reducing the interference between the support rails 2 and the moving cutting device 11, and achieving the purpose of conveniently adjusting the length and position of the support rails 2.

[0053] Example 2:

[0054] The difference between Example 2 of the present application and Example 1 is that:

[0055] Reference Figure 2 All the moving mechanisms 3 are installed at an angle on the fixed frame 21, each group of support plates 22 are parallel to each other, and each group of support plates 22 can be located on the same horizontal plane; all the moving mechanisms 3 are located between the silicon steel bar 10 and the frame 1, and the output ends of all the moving mechanisms 3 are tilted toward the silicon steel bar 10 to drive the corresponding support plate 22 close to or away from the silicon steel bar 10.

[0056] The implementation principle of a high-speed shear-to-length line in Example 2 of the present application is as follows:

[0057] When the output end of the inclined moving mechanism 3 contracts, the support plate 22 can be driven to move along the vertical direction and the width direction of the frame 1, increasing the space for the support plate 22 to make way for the cutting device 11 to move, further facilitating the position of the cutting device 11.

[0058] When the cutting device 11 has finished moving, the output end of the partial moving mechanism 3 is driven to extend, so that the support plate 22 not in contact with the cutting device 11 gradually approaches the silicon steel bar 10 and supports the silicon steel bar 10 .

[0059] Example 3:

[0060] The difference between Example 3 of the present application and Example 1 is that:

[0061] Reference Figure 3 The fixed frame 21 is mounted with several sets of guide rails 211, all of which are spaced apart along the length of the fixed frame 21. Each set of guide rails 211 is slidably mounted with a sliding block 2111 along the length of the guide rails 211. In this embodiment, the guide rails 211, sliding blocks 2111, support plate 22, and moving mechanism 3 are provided in a one-to-one correspondence, and the length of each set of guide rails 211 is parallel to the extension and retraction direction of the output end of the moving mechanism 3.

[0062] Reference Figure 3 Each group of support plates 22 is fixedly mounted on the side wall of the corresponding sliding block 2111 facing the cutting device 11, each group of moving mechanisms 3 is fixedly mounted on the fixed frame 21 through a bracket, and the output end of each group of moving mechanisms 3 is fixedly connected to the corresponding sliding block 2111.

[0063] The implementation principle of a high-speed shear-to-length line in Example 3 of the present application is as follows:

[0064] When the output end of the moving mechanism 3 contracts, the sliding block 2111 can be driven to drive the support plate 22 away from the cutting device 11 to make way for the movement of the cutting device 11; when the cutting device 11 has completed its movement, part of the output end of the moving mechanism 3 can be driven to extend to drive part of the sliding block 2111 to drive the corresponding support plate 22 to slide toward the direction close to the cutting device 11 and support the silicon steel bar 10.

[0065] Example 4:

[0066] The difference between Example 4 of the present application and Example 1 is that:

[0067] Reference Figure 4 、 Figure 5 and Figure 6 Each set of support plates 22 is rotatably connected to the side wall of the corresponding fixed frame 21 facing the cutting device 11, and the support plates 22 can be moved closer to or away from the silicon steel bar 10 by rotation. In this embodiment, the moving mechanism 3 includes several sets of fixed tubes 31, several sets of support rods 32, a driving assembly 33, a moving assembly 34, a reset assembly 35, and a locking assembly 36.

[0068] Reference Figure 4 and Figure 5All the fixed tubes 31 are fixedly connected to the fixed frame 21, and all the fixed tubes 31 are spaced apart along the length of the fixed frame 21. The fixed tubes 31, support rods 32, and support plates 22 are respectively provided in a one-to-one correspondence. Each set of fixed tubes 31 is located on the side of the corresponding support plate 22 facing away from the cutting device 11, and each set of support rods 32 is slidably connected to the inside of the corresponding fixed tube 31. Each set of support rods 32 slides toward the corresponding support plate 22. The side wall of the support rods 32 facing away from the frame 1 abuts against the lower surface of the corresponding support plate 22, providing auxiliary support for the support plate 22, so that the support plate 22 can support the silicon steel bar 10.

[0069] Reference Figure 4 and Figure 5 In this embodiment, each set of support rods 32 has a boss 321 integrally formed near the end of the corresponding support plate 22 and facing away from the side wall of the frame 1. The corresponding fixing tube 31 has a recess 310 formed at the end thereof for the boss 321 to abut against. When the support rods 32 drive the boss 321 to provide auxiliary support for the support plate 22, the boss 321 is used to maintain the corresponding support plate 22 in a horizontal position.

[0070] Reference Figure 4 and Figure 5 The moving assembly 34 is installed on each group of fixed frames 21. The moving assembly 34 includes a moving screw rod 341, a moving guide rod 342, a moving block 343 and a moving motor 344; the moving screw rod 341 and the moving guide rod 342 are both installed on the side wall of the fixed frame 21 away from the cutting device 11 through the support plate, and the length directions of the moving screw rod 341 and the moving guide rod 342 are parallel to the length direction of the fixed frame 21, and the moving screw rod 341 is rotatably connected to the support plate.

[0071] Reference Figure 4 and Figure 5 The moving block 343 is sleeved on the moving screw 341 and the moving guide rod 342, and the moving screw 341 is threadedly connected to the moving block 343. The moving motor 344 is fixedly mounted on the fixed frame 21, and the output end of the moving motor 344 is drivingly connected to the moving screw 341. The rotation of the output end of the moving motor 344 drives the moving screw 341 to rotate, thereby driving the moving block 343 to move along the length direction of the moving guide rod 342.

[0072] Reference Figure 4 and Figure 7The drive assembly 33 is mounted on each set of moving blocks 343 and includes a drive tube 331, a drive rod 332, a transmission rack 333, a drive gear 334, and a drive motor 335. The drive tube 331 is fixedly connected to the moving blocks 343 and can move along the length of the fixed frame 21 following the moving blocks 343. The drive rod 332 is slidably connected to the inside of the drive tube 331. The sliding direction of the drive rod 332 is parallel to the sliding direction of each set of support rods 32. The drive rod 332 can slide into the inside of any fixed tube 31 and gradually approach the support plate 22 by pushing the support rods 32.

[0073] Reference Figure 4 and Figure 7 The drive motor 335 is fixedly connected to the drive tube 331, and the drive gear 334 is fixedly sleeved on the output end of the drive motor 335. The transmission rack 333 is fixedly connected to the drive rod 332, and the length direction of the transmission rack 333 is parallel to the sliding direction of the drive rod 332. The drive tube 331 is provided with a driving notch for the drive gear 334 to engage with the transmission rack 333, so that the drive gear 334 and the transmission rack 333 engage with each other. The rotation of the drive gear 334 drives the transmission rack 333 to move the drive rod 332, thereby causing the drive rod 332 to move toward the support rod 32.

[0074] Reference Figure 6 and Figure 7 The reset assembly 35 is installed between each set of support rods 32 and the corresponding fixed tube 31. The reset assembly 35 includes a fixed block 351 and a reset member 352. In this embodiment, the reset member 352 can be a reset spring. The fixed block 351 is integrally formed on the side wall of each set of support rods 32, and the inner side wall of the corresponding fixed tube 31 is provided with a sliding groove 311 for the fixed block 351 to slide, so that the fixed block 351 can slide along the support rod 32.

[0075] Reference Figure 6 and Figure 7 The reset member 352 is located inside the sliding groove 311, and one end of the reset member 352 in the length direction is glued to the side wall of the fixing block 351 toward the support plate 22, and the other end of the reset member 352 is against the inner wall of the sliding groove 311, and the extension direction of the reset member 352 is parallel to the sliding direction of the support rod 32.

[0076] When the driving rod 332 pushes the support rod 32 toward the support plate 22, the fixed block 351 squeezes the reset member 352, causing the reset member 352 to deform and contract. When the driving rod 332 separates from the support rod 32, the reset member 352 gradually recovers its shape, pushing the fixed block 351 to gradually move the support rod 32 away from the support plate 22, thereby resetting the support rod 32. As the support rod 32 separates from the support plate 22, the support plate 22 rotates away from the silicon steel bar 10.

[0077] Reference Figure 5 and Figure 7 The locking assembly 36 is mounted on each set of support rods 32 and includes a rotating platform 361, a locking rod 362, a snap-on edge block 363, a rotating platform 364, and a rotating motor 365. The rotating platform 361 is rotatably connected to the end of each set of support rods 32 away from the support plate 22, and the locking rod 362 is fixedly connected to the peripheral wall of each set of rotating platforms 361. The side wall of the fixed tube 31 is provided with a sliding opening 312 along the length of the fixed tube 31, which can be inserted into the locking rod 362. This allows the locking rod 362 to move within the sliding opening 312 when the support rods 32 drive the rotating platform 361 and the locking rod 362 to move.

[0078] Reference Figure 5 and Figure 7 Each set of fixing tubes 31 has a locking notch 313 defined on its sidewall. The locking notch 313 is located at the end of the sliding opening 312 near the support plate 22 and communicates with the interior of the sliding opening 312, allowing the rotating platform 361 to drive the locking rod 362 to rotate and engage. Each set of locking notches 313 has a limiting notch 314 defined on the sidewall facing the support plate 22. When the locking rod 362 rotates and engages the locking notch 313, the reset assembly 35, through its own elastic force, drives the locking rod 362 to slide into the limiting notch 314, thereby preventing the locking rod 362 from disengaging from the locking notch 313.

[0079] Reference Figure 5 and Figure 7 The rotating platform 364 is rotatably connected to the end of each set of driving rods 332 toward the support rod 32, the rotating motor 365 is embedded in the inside of each set of driving rods 332, and the output end of the rotating motor 365 is fixedly connected to the rotating platform 364 to drive the rotating platform 364 to rotate.

[0080] Reference Figure 5 and Figure 7The engaging edges 363 are integrally formed on the side wall of the rotating platform 364 facing the support rod 32, and each set of rotating platforms 361 has an engaging groove 3611 on the side wall facing the rotating platform 364 that is adapted to fit the engaging edges 363 and allows the engaging edges 363 to abut against the engaging grooves 3611. When the engaging edges 363 abut against the inner sidewalls of the engaging grooves 3611, the rotating rotating platform 364 can be driven to rotate the rotating platform 361 and the locking rod 362.

[0081] The implementation principle of a high-speed shear-to-length line in Example 4 of the present application is as follows:

[0082] When the position of the cutting device 11 needs to be adjusted, the support rod 32 does not support the support plate 22. The support plate 22 is rotated in the direction away from the silicon steel bar 10 under the action of gravity, so that the support plate 22 provides space for the movement of the cutting device 11, reducing the interference between the displaced cutting device 11 and the support plate 22.

[0083] The moving motor 344 is started, and the output end of the moving motor 344 drives the moving screw 341 to rotate, so that the moving block 343 drives the driving tube 331 to move along the length direction of the frame 1, so that the driving tube 331 and part of the fixed tube 31 are connected to each other.

[0084] After the drive tube 331 is docked with the fixed tube 31, the drive motor 335 is started. The output end of the drive motor 335 drives the drive gear 334 to rotate. The meshing transmission between the drive gear 334 and the transmission rack 333 causes the transmission rack 333 to drive the drive rod 332 to gradually approach the support rod 32, and the engaging edge block 363 gradually presses into the engaging groove 3611. The moving drive rod 332 pushes the support rod 32 gradually toward the support plate 22, causing the support plate 22 to rotate toward the silicon steel bar 10, thereby supporting the silicon steel bar 10.

[0085] The support rod 32 drives the locking rod 362 to move to the connection point between the sliding opening 312 and the locking notch 313, and starts the rotating motor 365. The output end of the rotating motor 365 drives the rotating table 361, the clamping edge block 363, the rotating table 361 and the locking rod 362 to rotate, so that the locking rod 362 rotates and presses into the locking notch 313; and under the elastic force of the reset assembly 35, the locking rod 362 is driven to slide into the limiting notch 314 to limit the support rod 32 from sliding relative to the fixed tube 31, thereby driving the support rod 32 to maintain its supporting effect on the support plate 22.

[0086] When the support plate 22 needs to be reset, the driving assembly 33 is used to drive the support rod 32 to drive the locking rod 362 to slide in the direction close to the support plate 22, so that the locking rod 362 gradually disengages from the limiting notch 314. Then, the output end of the rotating motor 365 is controlled to reverse, so that the locking rod 362 reverses and resets from the inside of the locking notch 313 to the inside of the sliding opening 312; then, the output end of the driving motor 335 is controlled to reverse, so that the driving rod 332 gradually moves away from the support rod 32; at this time, the support rod 32 gradually resets away from the support plate 22 under the elastic force of the reset member 352, and the support plate 22 gradually disengages from the auxiliary support for the support plate 22, so that the support plate 22 is rotated in the direction away from the silicon steel bar 10 under the action of gravity, thereby achieving the reset of the support plate 22.

[0087] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
