Description

Technical Field

[0001] The present application relates to the technical field of metal processing equipment, and in particular to a thread rolling machine that is convenient for cleaning waste. Background Art

[0002] As a key thread processing equipment, thread rolling machine occupies an indispensable position in many mechanical manufacturing industries. It is widely used in the manufacturing of automobile parts, aerospace equipment, general mechanical processing and the production of various hardware products. It can efficiently and accurately process various specifications of threads on metal or other material workpieces, providing an important basic connection structure for product assembly and function realization.

[0003] However, the existing thread rolling machines have many technical defects in the actual operation process, among which the problem of waste residue is particularly prominent. During the thread rolling operation, metal waste will inevitably be generated and accumulated in the knife groove of the mold. Due to the lack of an effective automatic cleaning mechanism, these wastes tend to adhere tightly to the surface of the knife groove or become embedded in it. As the processing continues, the residual waste gradually increases. On the one hand, it will change the original precisely designed geometry and dimensional accuracy of the knife groove, causing deviations in the thread parameters of the subsequently processed parts. For example, it may cause uneven changes in the pitch of the thread and damage the tooth angle, which will seriously affect the reliability and sealing of the threaded connection, reduce the overall quality level of the product, and increase the defective rate. On the other hand, the friction and extrusion between the waste and the mold will increase the wear rate of the mold and shorten the service life of the mold. Summary of the invention

[0004] The purpose of the present application is to provide a thread rolling machine that is convenient for cleaning waste materials, in order to solve the problem of waste material accumulation in the tool groove of the mold.

[0005] The present application provides a thread rolling machine that is convenient for cleaning waste and adopts the following technical scheme: it includes a machine body, a first thread rolling plate movably connected to the machine body, a second thread rolling plate fixedly connected to the machine body, a power mechanism that drives the first thread rolling plate to move, a mobile frame slidably connected to the first thread rolling plate, a plurality of second sprocket groups installed at the end of the first thread rolling plate, a plurality of first sprocket groups installed on the mobile frame, a plurality of steel ball strings respectively embedded in the first sprocket group and the second sprocket group, and a driving component that drives the first sprocket group and the second sprocket group to rotate, the first thread rolling plate and the second thread rolling plate are both provided with a knife groove, the steel ball string can be embedded in the knife groove and can move along the inner wall of the knife groove, the driving component is arranged on the first thread rolling plate, and can convert the relative movement of the first thread rolling plate and the machine body into power to drive the first sprocket group and the second sprocket group.

[0006] By adopting the above method, the first thread rolling plate cooperates with the second thread rolling plate, and when the power mechanism drives them to reciprocate, the workpiece placed between the two is subjected to thread rolling operation, and the surface of the workpiece gradually forms the required thread shape through the interaction between the knife groove and the workpiece; waste is generated during the processing, most of the waste falls to the bottom, and a small part falls and gets stuck in the knife groove, and the driving component can convert the relative movement form of the first thread rolling plate and the machine body into a power form suitable for driving the first sprocket group and the second sprocket group to rotate, so that the steel ball string can be embedded in the knife groove of the first thread rolling plate and the second thread rolling plate, and move along the inner wall of the knife groove, and the relative movement of the steel ball and the inner wall of the knife groove is used to produce extrusion, friction and other effects on the waste remaining in the knife groove, so that the waste is squeezed out of the knife groove and taken out, so as to prevent the waste accumulation from affecting the thread rolling quality and the service life of the knife groove, keep the knife groove clean, and ensure the thread rolling processing accuracy.

[0007] Preferably, the driving assembly includes a rack fixedly connected to the machine body, a first rotating shaft and a second rotating shaft rotatably connected to the first thread rolling plate, and a gear connected to the first rotating shaft. The first rotating shaft and the second rotating shaft are connected by a bevel gear, and the gear is meshed with the rack. The second rotating shaft passes through a sprocket in the first sprocket group and the second sprocket group respectively, and the second rotating shaft is connected to the first sprocket group and the second sprocket group with a sliding key respectively.

[0008] By adopting the above method, the linear motion generated by the relative movement of the first thread rolling plate and the machine body is gradually converted into a rotary power form suitable for the rotation of the first sprocket group and the second sprocket group through the meshing of the rack and the gear, the connection between the rotating shafts and the sliding key connection, and the power is accurately transmitted to the sprocket group to drive the steel ball string to move in the knife groove. In this way, the function of using the movement of the first thread rolling plate to drive the steel ball string to clean the waste in the knife groove is realized, and the linkage between the steel ball string and various related components participates in the adjustment of the movement state of the first thread rolling plate, ensuring that the thread rolling machine can perform thread rolling processing efficiently and stably, and improve the thread rolling quality and the overall performance of the equipment; In addition, the drive assembly is a relatively complex steel ball string program control system. Since the inclination angles of the knife grooves are varied, the vertical and horizontal movements of the steel ball string must have a specific proportional relationship in order to slide smoothly in the knife groove; due to the meshing of the gear rack, the first thread rolling plate moves one end distance each time, and the gear rotates a specific angle, thereby linking the movement of the first thread rolling plate with the rotation of the first rotating shaft. The second rotating shaft drives the steel ball string to rotate through the sprocket group, so that the vertical movement distance of the second rotating shaft is related to the rotation of the second rotating shaft, so that the specific proportional relationship between the vertical and horizontal movements of the steel ball string can be achieved by simply adjusting the transmission ratio of the first rotating shaft to the second rotating shaft; this is achieved by replacing the bevel gear group with different transmission ratios.

[0009] Preferably, the first sprocket group is provided with at least one sprocket, the first thread rolling plate is provided with a through groove along the length direction, the movable frame is arranged in the through groove, the first thread rolling plate at least partially passes through the movable frame, the first sprocket group is located on the outside of the first thread rolling plate, the steel ball string is arranged between the movable frame and the first thread rolling plate, and the steel ball string surrounds at least part of the first thread rolling plate.

[0010] By adopting the above method, the first thread rolling plate at least partially passes through the moving frame, so that the moving frame can move at the position where the first thread rolling plate passes through, and the steel bead string is arranged between the moving frame and the first thread rolling plate, so that the steel bead string surrounds the position where the first thread rolling plate passes through. This surrounding structure makes the steel bead string have a relatively fixed position during the operation process and will not be easily displaced. During the operation of the equipment, especially when the moving frame moves in the thread rolling plate groove, the steel bead string can be kept in a suitable position to prevent the steel bead string from being offset and deformed; The movement of the mobile frame in the thread rolling plate groove will drive the steel ball string to roll, and the rolling of the steel ball string not only depends on its own spherical structure, but is also closely related to the movement direction and speed of the mobile frame. In this process, the steel ball string can automatically adjust the strength and direction of waste cleaning according to the different movement states of the mobile frame. For example, when the mobile frame moves quickly, the rolling speed of the steel ball string increases, and the ability to clean up waste is enhanced; when the mobile frame moves slowly for fine thread rolling operations, the steel ball string can still gradually clean up the newly generated waste under a small power action. This synergistic effect with the movement of the mobile frame greatly improves the efficiency of waste cleaning and can adapt to the needs of different thread rolling process stages.

[0011] Preferably, the second sprocket set is provided with at least two sprockets, the steel bead string passes around and is embedded in the sprockets in the second sprocket set, and the steel bead string is at least partially biased towards the first thread rolling plate.

[0012] By adopting the above method, the movement trajectory of the steel ball string is more clear and stable through the guidance of the second sprocket set. Compared with the case without sprocket guidance, this structure can prevent the steel ball string from being excessively twisted or deviating from the predetermined route during the movement, so that the steel ball string can circulate according to the design requirements; in the process of cleaning waste, the partially offset steel ball string can better contact the knife groove of the second thread rolling plate.

[0013] Preferably, the first thread rolling plate is rotatably connected to a third rotating shaft, the third rotating shaft sleeve is provided with a flywheel column, the third rotating shaft is connected to a sprocket sliding key in the second sprocket group, and a one-way rotating component is provided between the flywheel column and the third rotating shaft. The one-way rotating component ensures that the flywheel column can only be driven to rotate when the third rotating shaft rotates in a certain direction.

[0014] By adopting the above method, the problem of uneven speed of the first thread rolling plate during movement can be better solved. The existing thread rolling machine is driven by a crank slider mechanism. Since the rotational motion of the crank is converted into the linear reciprocating motion of the first thread rolling plate through the connecting rod, its kinematic characteristics determine that the speed of the slider changes within a stroke cycle. At the start and end positions of the stroke, the slider speed approaches zero, and the speed reaches the maximum value in the middle part of the stroke. This speed change is caused by the geometric relationship between the circular motion of the crank and the connecting rod and the slider. The uneven speed of the first thread rolling plate will be directly reflected in the thread processing. When the speed is fast, the thread rolling plate has a large force on the workpiece and a short action time, which may cause excessive extrusion of the thread tooth profile, making it difficult to accurately control the parameters such as the pitch and tooth angle of the thread, resulting in deviations; the rapid change in speed will also cause vibration and impact during the thread rolling process. These vibrations and impacts will be transmitted to the workpiece and the thread rolling plate, causing the surface roughness of the processed thread to increase and the finish to deteriorate.

[0015] The flywheel column has a large moment of inertia. When the third shaft transmits the power from the second sprocket group to the flywheel column (in the direction allowed by the one-way rotating component), the flywheel column will store energy. In the case of uneven speed of the thread rolling plate, for example, when the speed of the thread rolling plate suddenly increases, the flywheel column will absorb excess energy and store this energy by increasing its own rotation speed, thereby slowing down the increase in the speed of the thread rolling plate; when the speed of the thread rolling plate slows down, the flywheel column releases the stored energy and provides additional power support for the thread rolling plate by reducing its own rotation speed, thereby reducing the speed drop, thereby effectively adjusting the movement speed of the thread rolling plate to make it closer to uniform motion, improving the thread rolling quality and the overall performance of the equipment, and reducing a series of problems caused by uneven speed, such as reduced thread accuracy, increased mold wear, and fatigue damage to equipment components.

[0016] The one-way rotation assembly restricts the third shaft to rotate in a specific direction to drive the flywheel column to rotate, which is to ensure that the energy is stored and released in a way that is conducive to the stable movement of the screw plate. Without this restriction, when the third shaft rotates in the opposite direction, the flywheel column also rotates in the opposite direction, and the energy storage and release will become chaotic; during normal operation, when the first screw plate accelerates, the third shaft rotates in the positive direction to drive the flywheel column to store energy. Without the one-way restriction, when the screw plate decelerates and the third shaft rotates in the opposite direction, the flywheel column will interfere with the rotation of the third shaft.

[0017] Preferably, the one-way rotation assembly includes a ratchet arranged at the end of the flywheel column, a first turntable fixedly connected to the third rotating shaft, and a plurality of pawls and a first elastic sheet arranged on the first turntable, one end of the first elastic sheet is connected to the pawl and the other end is connected to the first turntable, and the first elastic sheet forces the end of the pawl to abut against the ratchet.

[0018] By adopting the above method, when the third rotating shaft rotates in the positive direction, the first rotating disk rotates accordingly, driving the pawl to rotate together. Due to the pre-tightening force of the first elastic sheet, the end of the pawl is tightly pressed on the ratchet, and the pawl pushes the ratchet, so that the flywheel column rotates with the third rotating shaft. At this time, the power is transmitted from the third rotating shaft to the flywheel column through the cooperation of the pawl and the ratchet, realizing a one-way power transmission, so that the flywheel column can store energy in the expected direction and participate in the regulation of the movement of the first thread rolling plate.

[0019] When the third shaft rotates in the reverse direction, the pawl is lifted up by the inclined surface of the ratchet tooth, overcomes the preload force of the first elastic sheet and leaves the ratchet tooth. At this time, the effective contact between the pawl and the ratchet tooth is cut off, and the power cannot be transmitted from the third shaft to the flywheel column. This design effectively prevents the flywheel column from being driven when the third shaft rotates in the reverse direction, ensures the realization of unidirectional rotation, and avoids system disorder and interference with the movement adjustment of the thread rolling plate that may be caused by reverse rotation.

[0020] Preferably, the third rotating shaft sleeve is provided with a second rotating disk, the second rotating disk is fixedly connected with a limiting rod capable of passing through the first rotating disk, the limiting rod can abut against a side of the pawl, the third rotating shaft sleeve is provided with a first spring, the first spring is located between the first rotating disk and the second rotating disk, the first spring forces the second rotating disk to move away from the first rotating disk, a first ring is provided on the third rotating shaft, the first ring is rotatably connected to the second rotating disk, the first ring is fixedly connected with a moving column, the moving column slides on the machine body, the third rotating shaft sleeve is provided with a second ring, the second ring is provided with a track groove, the first ring is fixedly connected with a fixed block, and the fixed block is slidably connected to the track groove.

[0021] By adopting the above method, only when the third rotating shaft rotates in a specific direction, the kinetic energy of the flywheel column will affect the rotation of the third rotating shaft, so that the speed of the first thread rolling plate is adjusted. When the third rotating shaft rotates in a specific direction, under the action of the track groove and the fixed block, the first ring can move, and the first ring pushes the limit rod, so that the limit rod abuts against one side of the pawl, so that the ratchet pawl becomes a rigid connection, so that the flywheel column can affect the flywheel column through the first rotating disk.

[0022] Preferably, an annular groove is provided on the third rotating shaft, the second ring is arranged in the annular groove, a second elastic sheet is provided between the second ring and the inner wall of the annular groove, evenly distributed protrusions are provided at the bottom of the annular groove, the second elastic sheet is arc-shaped, and the second elastic sheet can abut against two adjacent protrusions.

[0023] By adopting the above method, when the second ring and the first ring cannot rotate in one direction, the second elastic sheet itself is elastically deformed, so that the third rotating shaft can continue to rotate relative to the second ring.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The driving component converts the relative movement between the first thread rolling plate and the machine body into the power to drive the first sprocket group and the second sprocket group to rotate, so that the steel ball string can be embedded in the knife groove and move along the inner wall. The relative movement between the steel ball and the inner wall of the knife groove is used to squeeze and rub the residual waste in the knife groove, squeeze the waste out, avoid the accumulation of waste affecting the thread rolling quality and the service life of the knife groove, keep the knife groove clean, and ensure the thread rolling processing accuracy; the moving frame moves in the thread rolling plate groove to drive the steel ball string to roll. The steel ball string can automatically adjust the waste cleaning force and direction according to the different movement states of the moving frame, adapt to the needs of different thread rolling process stages, and greatly improve the waste cleaning efficiency.

[0025] 2. Utilizing the large moment of inertia of the flywheel column, the flywheel column can store or release energy when the third shaft transmits power to the flywheel column. When the speed of the thread rolling plate is uneven, if the speed increases, the flywheel column absorbs excess energy to slow down the speed increase; when the speed slows down, the energy is released to provide additional power support, reduce the speed drop, make the thread rolling plate movement closer to uniform speed, improve the thread rolling quality, and reduce the problems of reduced thread accuracy, increased mold wear, and fatigue damage of equipment components caused by uneven speed.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0029] The embodiment of the present application discloses a thread rolling machine which is convenient for cleaning waste materials.

[0030] Example 1, reference Figure 1-Figure 3 , a thread rolling machine that is convenient for cleaning waste, including a body 1 as a supporting frame of the entire equipment, providing a stable installation foundation for each component. The first thread rolling plate 2 is movably connected to the body 1 through a guide slider structure, and can perform linear reciprocating motion on the body 1. The second thread rolling plate 3 is fixedly connected to the body 1, and is arranged opposite to the first thread rolling plate 2. The first thread rolling plate 2 and the second thread rolling plate 3 are both provided with knife grooves 9, the shapes of which match the thread shapes required for the wire to be processed, and are used to form threads on the wire during the thread rolling process. The power mechanism 4 adopts a slider mechanism structure driven by a motor, so as to realize the thread rolling action of the wire placed between the two thread rolling plates. The first thread rolling plate 2 is provided with a through groove 26, and the moving frame 27 is slidably connected to the through groove 26 and can continue to slide along the through groove 26. The moving frame 27 is provided with a first sprocket group 7, and the first sprocket group 7 is provided with a sprocket arranged on the moving frame 27, for example. A second sprocket set 6 is correspondingly installed at the end of the first thread rolling plate 2. For example, the second sprocket set 6 is provided with two sprockets at the end of the first thread rolling plate 2. The steel bead string 8 is respectively embedded in the first sprocket set 7 and the second sprocket set 6, and the steel bead string 8 can be embedded in the knife groove 9 of the first thread rolling plate 2 and the second thread rolling plate 3, and move along the inner wall of the knife groove 9. The steel bead string 8 is composed of a plurality of steel balls connected in series, and the arrangement of the steel bead string 8 in the sprocket set enables the steel bead string 8 to roll in the knife groove 9 when the sprocket set rotates, thereby reducing the friction with the inner wall of the knife groove 9 and assisting the thread rolling process of the wire.

[0031] refer to Figure 2 and Figure 3The first thread rolling plate 2 is provided with a driving assembly, which includes a rack 24 fixedly connected to the machine body 1, a first rotating shaft 21 and a second rotating shaft 22 rotatably connected to the first thread rolling plate 2, and a gear 25 connected to the first rotating shaft 21. The first rotating shaft 21 is connected to the second rotating shaft 22 through a bevel gear 25, the gear 25 is meshed with the rack 24, the second rotating shaft 22 passes through a sprocket in the first sprocket group 7 and the second sprocket group 6 respectively, and the second rotating shaft 22 is connected to the first sprocket group 7 and the second sprocket group 6 by a sliding key. When the first thread rolling plate 2 moves relative to the machine body 1 under the action of the power mechanism 4, since the rack 24 is fixed on the machine body 1, the gear 25 meshed with the rack 24 will rotate with the movement of the first thread rolling plate 2. The rotation of the gear 25 drives the first rotating shaft 21 to rotate, and the first rotating shaft 21 transmits power to the second rotating shaft 22 through the bevel gear 25. Due to the sliding key connection between the second rotating shaft 22 and the first sprocket group 7 and the second sprocket group 6, the rotation of the second rotating shaft 22 can be converted into the rotational power of the first sprocket group 7 and the second sprocket group 6, thereby driving the steel ball string 8 to move in the knife groove 9. This design cleverly converts the linear motion of the first thread rolling plate 2 into the rotational power of the sprocket group, and realizes the function of using the movement of the first thread rolling plate 2 to drive the steel ball string 8 to clean the waste in the knife groove 9. At the same time, the linkage between the steel ball string 8 and various related components can also participate in the adjustment of the movement state of the first thread rolling plate 2, ensuring the efficient and stable operation of the thread rolling machine.

[0032] refer to Figure 4 and Figure 5 , the first thread rolling plate 2 at least partially passes through the moving frame 27, the first sprocket set 7 is located outside the first thread rolling plate 2, the steel ball string 8 is arranged between the moving frame 27 and the first thread rolling plate 2, and the steel ball string 8 surrounds at least part of the first thread rolling plate 2. The steel ball string 8 bypasses and is embedded in the sprocket in the second sprocket set 6, and the steel ball string 8 is at least partially biased towards the first thread rolling plate 2. The structure in which the first thread rolling plate 2 passes through the moving frame 27 and is surrounded by the steel ball string 8 enables the steel ball string 8 to have a relatively fixed position during work and is not easy to shift. When the moving frame 27 moves in the thread rolling plate slot 26, it drives the steel ball string 8 to roll, and the rolling of the steel ball string 8 is closely related to the movement direction and speed of the moving frame 27. For example, when the moving frame 27 moves quickly, the rolling speed of the steel ball string 8 is accelerated, and the ability to clean up waste is enhanced; when it moves slowly for fine thread rolling, the steel ball string 8 can still clean up newly generated waste. The second sprocket set 6 guides the steel ball string 8, making the movement trajectory of the steel ball string 8 clear and stable, preventing it from twisting or deviating from the predetermined route, and the partially offset steel ball string 8 can better contact the knife groove 9 of the second thread rolling plate 3, thereby improving the waste cleaning effect.

[0033] refer to Figure 4The structure in which the first thread rolling plate 2 passes through the movable frame 27 and is surrounded by the steel ball string 8 makes the steel ball string 8 have a relatively fixed position during operation and is not easy to shift. When the movable frame 27 moves in the thread rolling plate groove 26, it drives the steel ball string 8 to roll, and the rolling of the steel ball string 8 is closely related to the movement direction and speed of the movable frame 27. For example, when the movable frame 27 moves quickly, the rolling speed of the steel ball string 8 is accelerated, and the ability to clean up waste is enhanced; when it moves slowly for fine thread rolling, the steel ball string 8 can still clean up newly generated waste. The guiding effect of the second sprocket set 6 on the steel ball string 8 makes the movement trajectory of the steel ball string 8 clear and stable, preventing it from twisting or deviating from the predetermined route, and the partially offset steel ball string 8 can better contact the knife groove 9 of the second thread rolling plate 3, thereby improving the waste cleaning effect.

[0034] refer to Figure 6-Figure 7 The first thread rolling plate 2 is rotatably connected to the third rotating shaft 23, and the third rotating shaft 23 is sleeved with a flywheel column 5. The third rotating shaft 23 is connected to a sprocket sliding key in the second sprocket group 6. A ratchet 51 is provided at the end of the flywheel column 5, and the third rotating shaft 23 is fixedly connected to the first rotating disk 52. The first rotating disk 52 is provided with 6 pawls 53 and 6 first elastic sheets 531. One end of the first elastic sheet 531 is connected to the pawl 53 and the other end is connected to the first rotating disk 52. The first elastic sheet 531 forces the end of the pawl 53 to abut against the ratchet 51. The first elastic sheet 531 is located on the side of the forward rotation direction of the pawl 53. When the third rotating shaft 23 rotates forward, the first rotating disk 52 rotates to drive the pawl 53 to rotate. Due to the pre-tightening force of the first elastic sheet 531, the pawl 53 pushes the ratchet 51, so that the flywheel column 5 follows the third rotating shaft 23 to rotate, thereby realizing unidirectional power transmission. When the third rotating shaft 23 rotates in the reverse direction, the pawl 53 is lifted up by the inclined surface of the ratchet tooth 51 , overcomes the preload force of the first elastic sheet 531 , and leaves the ratchet tooth 51 , thereby cutting off the power transmission.

[0035] refer to Figure 7-Figure 8The third rotating shaft 23 is sleeved with a second rotating disk 54, and the second rotating disk 54 is fixedly connected with a limiting rod 55 that can penetrate the first rotating disk 52, and the limiting rod 55 can abut against a side of the pawl 53, and the limiting rod 55 is located on the side of the reversal direction of the pawl, and the third rotating shaft 23 is sleeved with a first spring 56, and the first spring 56 is located between the first rotating disk 52 and the second rotating disk 54, and the first spring 56 forces the second rotating disk 54 to move away from the first rotating disk 52, and a first ring 59 is provided on the third rotating shaft 23, and the first ring 59 is rotatably connected to the second rotating disk 54, and the first ring 59 is fixedly connected with a moving column 57, and the moving column 57 slides on the body 1, and the third rotating shaft 23 is sleeved with a second ring 58, and the second ring 58 is provided with a track groove 582, and the first ring 59 is fixedly connected with a fixed block 591, and the fixed block 591 is slidably connected to the track groove 582. The third rotating shaft 23 is provided with an annular groove 232, the second collar 58 is arranged in the annular groove 232, a second elastic sheet 581 is arranged between the second collar 58 and the inner wall of the annular groove 232, the bottom of the annular groove 232 is provided with evenly distributed protrusions 231, the second elastic sheet 581 is in an arc shape, and the second elastic sheet 581 can abut against two adjacent protrusions 231. Only when the third rotating shaft 23 rotates in the positive direction, under the action of the track groove 582 and the fixing block 591, the first collar 59 moves, pushes the limit rod 55 to abut against one side of the pawl 53, so that the ratchet 51 and the pawl 53 become rigidly connected, and the flywheel column 5 can affect the third rotating shaft 23 through the first rotating disk 52. When the second collar 58 and the first collar 59 cannot rotate in one direction, the second elastic sheet 581 itself is elastically deformed, so that the third rotating shaft 23 can continue to rotate relative to the second collar 58.

[0036] When the third rotating shaft 23 rotates forward for the first time, since the ratchet 51 and the pawl 53 become rigidly connected at this time, the first rotating disk 52 rotates to drive the pawl 53 to rotate. Due to the preload force of the first elastic sheet 531, the pawl 53 pushes the ratchet 51, so that the flywheel column 5 rotates with the third rotating shaft 23, and the power is transmitted in one direction. When the third rotating shaft 23 rotates in the opposite direction, the pawl 53 is lifted up by the inclined surface of the ratchet 51, overcomes the preload force of the first elastic sheet 531 and leaves the ratchet 51, cutting off the power transmission. Since the flywheel column 5 is a large mass object, when the power transmission is cut off, the flywheel column 5 keeps rotating under the action of the inertial force. When the third rotating shaft 23 rotates forward for the second time, the flywheel column 5 is in high-speed forward rotation at the beginning, and the speed of the flywheel column 5 is greater than the speed of the third rotating shaft 23. The flywheel column 5 will drive the third rotating shaft 23 to rotate, thus realizing the release of the energy of the flywheel column 5. When the speed of the third rotation 23 exceeds that of the flywheel column 5 under the action of the power mechanism 4, the third rotation 23 will drive the flywheel column 5 to rotate, thereby realizing energy storage, so that the speed of the thread rolling plate is in a relatively stable state during the processing.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
