Technical Field
[0001] This invention relates to the field of waste material winding technology, specifically to a winding device for thin steel plates after punching and pressing. Background Technology
[0002] Stamping can be understood as a specific processing step or technology in the stamping process. Its core is to use a press and mold to apply external force to materials such as sheet metal, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. After the sheet stamping process is completed, the sheet waste needs to be wound up by a winding device. In the existing technology, it is difficult for the winding equipment to operate continuously throughout the waste collection process. It usually needs to stop intermittently during the winding process, such as waiting for a new batch of waste to be generated before restarting. This working mode not only aggravates the wear of the drive motor, but also, especially in the later stage of collection, when the weight of the waste accumulated on the winding shaft increases significantly, the equipment load reaches its peak, and the risk of motor overload and mechanical wear will become more prominent. To address this, we propose a winding device for thin steel sheets after stamping. Summary of the Invention

Detailed Implementation
[0016] 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.
[0017] Please see Figures 1-10 The present invention provides a technical solution: a coiling device for thin steel plates after stamping and blanking, comprising a housing 1 and a winding shaft 11 mounted on the housing 1, a drive motor 12 installed inside the housing 1, and further comprising: The reduction assembly 2 is located inside the housing 1. The drive motor 12 is connected to the winding shaft 11 through the reduction assembly 2. When the drive motor 12 starts, the output torque of the drive motor 12 is reduced and amplified and then transmitted to the winding shaft 11 to drive the winding shaft 11 to rotate and realize the automatic winding and collection of waste. The inertial recovery component 3 is disposed on the inner wall of the housing 1 and is connected to the winding shaft 11 in a transmission manner. When the drive motor 12 stops running, it recovers the rotational kinetic energy generated by the inertia of the winding shaft 11 through the mechanical energy storage structure and converts the energy into elastic potential energy for storage. The inertia release component 4 is located inside the housing 1 and is connected to the winding shaft 11 and the inertia recovery component 3. When the drive motor 12 restarts, it releases the potential energy stored in the inertia recovery component 3 to the winding shaft 11, forming an auxiliary driving force in the same direction as the output torque of the drive motor 12, so as to reduce the motor starting load. Specifically, this device uses a speed reduction component 2 to amplify torque and ensure smooth winding, an inertial recovery component 3 to store the kinetic energy of the winding shaft 11 when the machine stops to prevent the waste from loosening, and an inertial release component 4 to release potential energy to assist the drive when restarting. The three components work together to reduce the motor load and energy consumption, improve the stability and energy efficiency of the equipment, and are especially suitable for high-frequency start-stop collection scenarios of stamping waste.
[0018] The reduction assembly 2 includes a second shaft 21 rotatably connected to the outer casing 1, which is connected to the winding shaft 11. One end of the second shaft 21 is fixedly connected to a worm gear 22. A third shaft 23 is rotatably connected to the outer casing 1. One end of the third shaft 23 is fixedly connected to a worm 24 that meshes with the worm gear 22. One end of the third shaft 23 is fixed to the output shaft of the drive motor 12. When the drive motor 12 is started, the third shaft 23 is rotated, which in turn drives the worm 24 to rotate, which in turn drives the worm gear 22 to rotate, thereby driving the second shaft 21 to rotate, which in turn drives the winding shaft 11 to rotate. This reduces and increases the output torque of the drive motor 12 and then transmits it to the winding shaft 11. At the same time, through the design of the worm gear 22 and the worm 24, a self-locking effect is achieved on the second shaft 21 when the drive motor 12 stops rotating.
[0019] The inertial recovery assembly 3 includes a hollow column 25 fixedly connected to shaft 21. One end of the winding shaft 11 is located inside the hollow column 25 and rotatably connected to it. A ratchet assembly 26 is provided between the hollow column 25 and the winding shaft 11. A hollow ring 27 is provided on the winding shaft 11. An elastic element 28 is provided between the hollow ring 27 and the hollow column 25. During the rotation of the winding shaft 11 relative to shaft 21, the hollow ring 27 is driven to rotate relative to the hollow column 25, so that the elastic element 28 deforms and stores force. Specifically, when the device is working normally, the drive motor 12 drives the winding shaft 11 to rotate in one direction through the ratchet assembly 26 to achieve waste winding; when the drive motor 12 stops, the winding shaft 11 continues to rotate under inertia, and drives it to rotate synchronously through the transmission connection with the hollow ring 27; at this time, due to the self-locking of the shaft 21, the rotation of the hollow ring 27 will compress the elastic element 28, such as a spring, to achieve elastic energy storage of inertial energy; at the same time, the one-way locking characteristic of the ratchet assembly 26 is automatically triggered during the inertial recovery stage, so that the winding shaft 11 remains unidirectionally locked during the energy storage process of the elastic element 28.
[0020] The inertial release assembly 4 includes a locking member 29 disposed between the hollow ring 27 and the winding shaft 11 for locking the hollow ring 27 and the winding shaft 11, a locking member 31 disposed between the outer shell 1 and the hollow ring 27 for locking the hollow ring 27 and the outer shell 1, and a switching member 32 connected to the locking member 29 and the locking member 31 is disposed inside the outer shell 1. Specifically, before starting the drive motor 12, the switching component 32 is activated, firstly locking the hollow ring 27 to the outer casing 1 using the second locking component 31, and then releasing the lock between the hollow ring 27 and the winding shaft 11 using the first locking component 29. After that, the hollow ring 27 will be disconnected from the winding shaft 11 and fixed to the outer casing 1, thereby transferring the energy of the elastic component 28 to the second shaft 21. Then, when the drive motor 12 is started, the energy stored in the elastic component 28 is automatically released to assist the device in starting.
[0021] The ratchet assembly 26 includes multiple ratchet protrusions 33 uniformly fixedly connected to the inner wall of the hollow column 25, and a rotating ring 34 fixedly connected to one end of the winding shaft 11. Multiple shafts 35 are uniformly rotatably connected to the rotating ring 34. A jack tooth 36 that meshes with the ratchet protrusions 33 is fixedly connected to the shaft 35. A torsion spring 37 is sleeved on the shaft 35. The two ends of the torsion spring 37 are fixed to the jack tooth 36 and the rotating ring 34, respectively. When the shaft 21 is rotated, the hollow column 25 is driven to rotate, and then the ratchet protrusions 33 push the jack tooth 36 to rotate, thereby driving the winding shaft 11 fixedly connected to the rotating ring 34 to rotate.
[0022] The elastic element 28 includes multiple connecting plates 38 uniformly fixedly connected to the hollow column 25. Multiple connecting plates 39 corresponding to the connecting plates 38 are uniformly fixedly connected to the hollow ring 27. A telescopic rod 41 is rotatably connected between the connecting plates 39 and the connecting plates 38 via a rotating shaft. A storage spring 42 is sleeved on the telescopic rod 41. The two ends of the storage spring 42 are fixed to the two ends of the telescopic rod 41 respectively. When the hollow ring 27 rotates relative to the hollow column 25, the storage spring 42 will be compressed.
[0023] Locking component 29 includes a fixed friction disc 43 fixedly connected to the winding shaft 11, a connecting pipe 44 fixedly connected to one side of the hollow ring 27, a movable friction disc 45 slidably connected to the connecting pipe 44, a groove 46 provided on the connecting pipe 44, a sliding protrusion 47 fixedly connected to the movable friction disc 45, one end of the sliding protrusion 47 being located in the groove 46 and slidably connected to its inner wall, used to guide and limit the movement of the movable friction disc 45; A force-bearing ring 48 is provided on the other side of the hollow ring 27. A connecting post 49 is fixedly connected to one side of the force-bearing ring 48. One end of the connecting post 49 slides through the connecting plate 38 and is fixedly connected to the movable friction disk 45. Specifically, when the movable friction disk 45 is pressed against the fixed friction disk 43, the hollow ring 27 is locked to the winding shaft 11. At this time, rotating the winding shaft 11 will drive the hollow ring 27 to rotate. Subsequently, the connecting post 49 is moved by the movable force-bearing ring 48, which in turn drives the movable friction disk 45 to disengage from the fixed friction disk 43, thereby disconnecting the connection between the winding shaft 11 and the hollow ring 27.
[0024] Locking component 2 31 includes a rotating post 51 disposed on one side of the hollow ring 27. The rotating post 51 is connected to the hollow ring 27 by a one-way ratchet assembly. The winding shaft 11 slides through the rotating post 51 and is rotatably connected. A movable friction disk 2 52 is slidably connected to the rotating post 51. A fixed friction disk 43 is also fixedly connected to the outer shell 1. A sliding protrusion 47 is also fixedly connected to the movable friction disk 2 52. A sliding groove 46 is also provided on the rotating post 51. One end of the sliding protrusion 47 is located in the sliding groove 46 and is slidably connected to its inner wall. A force-bearing ring 53 is provided on one side of the movable friction disc 52. A connecting post 49 is also fixedly connected between the force-bearing ring 53 and the movable friction disc 52. Specifically, when the movable friction disc 52 is pressed into contact with the fixed friction disc 43 fixedly connected to the outer shell 1, the mechanical interlocking action of the one-way ratchet assembly realizes the one-way braking lock between the hollow ring 27 and the outer shell 1. This design adopts a two-way functional isolation mechanism: on the one hand, the one-way locking characteristic of the ratchet assembly can effectively prevent the hollow ring 27 from reversing and causing the elastic element 28 to be released unexpectedly, ensuring that the inertial energy is fully stored; on the other hand, when the drive motor 12 is running normally, even if the hollow ring 27 does not disengage from the outer shell 1 in time due to mechanical delay, the forward free rotation characteristic of the one-way ratchet assembly will not cause motion interference to the winding shaft 11, thereby ensuring the continuity and stability of the waste winding process. Subsequently, the connecting column 49 is moved by the moving force ring 2 53, which in turn causes the moving friction disc 2 52 to disengage from the fixed friction disc 43 that is fixedly connected to the outer shell 1, thereby disconnecting the connection between the outer shell 1 and the hollow ring 27.
[0025] The switching component 32 includes an annular body 54 rotatably connected to the force-receiving ring 48. A sliding column 55 is symmetrically fixedly connected to the annular body 54. An annular body 56 is rotatably connected to the force-receiving ring 53. A sliding column 57 is symmetrically fixedly connected to the annular body 56. An electric push rod 58 is fixedly connected to the outer shell 1. A U-shaped plate 59 is fixedly connected to the extended end of the electric push rod 58. A guide groove 61 is provided on the U-shaped plate 59. One end of the sliding column 55 and the sliding column 57 are both located in the guide groove 61. When the electric push rod 58 is activated, the guide groove 61 is used to drive the sliding column 55 and the sliding column 57 to move.
[0026] The guide groove 61 includes a straight guide groove 62 formed on the U-shaped plate 59, one end of the sliding column 55 is located in the straight guide groove 62 and is slidably connected to its inner wall, and the U-shaped plate 59 is provided with an inclined guide groove 63 that communicates with the straight guide groove 62. An inclined guide groove 2 64 is provided on the U-shaped plate 59, one end of the sliding column 2 57 is located in the inclined guide groove 2 64 and is slidably connected to its inner wall, and a straight guide groove 2 65 connected to the inclined guide groove 2 64 is provided on the U-shaped plate 59. Specifically, in the initial state of the device, the movable friction disk 45 and the fixed friction disk 43, which are fixedly connected to the winding shaft 11, maintain a tight contact, and the hollow ring 27 and the winding shaft 11 are initially locked by friction. After the inertial recovery stage is completed and the device stops completely, the electric push rod 58 starts and drives the U-shaped plate 59 to translate. Its movement process is divided into two stages: First stage (initial displacement segment): The sliding column 55 slides along the straight guide groove 62 to maintain the locked state between the hollow ring 27 and the winding shaft 11; The sliding column 2 57 slides synchronously along the inclined guide groove 2 64, pushing the movable friction disk 2 52 to press against the fixed friction disk 43 fixedly connected to the outer shell 1, thus completing the one-way braking lock between the hollow ring 27 and the outer shell 1. Second stage (continuous displacement segment): The sliding column 55 rotates into the inclined guide groove 63 and slides, driving the moving friction disk 45 to separate from the fixed friction disk 43 of the winding shaft 11, thus releasing the connection between the hollow ring 27 and the winding shaft 11. The sliding column 57 slides along the straight guide groove 65, keeping the hollow ring 27 locked to the outer shell 1. Through the aforementioned phased guide channel control, the timing control of "first establishing the lock of the outer shell 1 and then releasing the connection of the winding shaft 11" is achieved, ensuring that the inertial recovery system always maintains at least one mechanical lock during the state switching process, thus avoiding accidental energy release or component movement.
