Description

Technical Field

[0001] The invention belongs to the technical field of metal plate rolling, and in particular relates to a metal plate winding pipe making device with variable diameter. Background Art

[0002] Many metal pipes are made by rolling metal plates, and then the side seams are connected by welding. Among them, the small short tube rolling machine is a commonly used production equipment; this equipment can roll square metal sheets on a stick, use the stick as a mold, and complete the pipe making.

[0003] Although this type of production line and production process is relatively mature, the production line is often composed of multiple independent devices connected together, occupying a large area; a series of actions such as loading, lowering, rolling, and unloading require independent modules for driving and motion guidance, and the overall structure is relatively complex. When it is mass-produced as a standard model, the cost is relatively high.

[0004] In order to solve the cost problem during mass production, the present invention conducts an in-depth analysis of its movement mechanism and structure, and proposes a metal plate winding pipe making device with variable diameter based on automatic linkage control. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a variable diameter metal plate winding tube making device; the automatic feeding and withdrawing mechanism can control the lateral sliding of the withdrawing fork to remove the wound metal tube, and can also move downward longitudinally to make the originally separated drum body and shaping roller close to each other, thereby creating conditions for extruding the metal plate and deforming it; the position sensing contact, the shaping roller and the feeding platform constitute three points that contact the metal plate at the same time, and the metal plate can be extruded and bent through the rigid limiting of these three contact points.

[0006] Moreover, the lifting and lowering of the first slider and the second slider can be controlled through the two-stage adaptive downward pressure mechanism. Through the driving motor as a driving source, not only can the lateral movement of the material return fork and the lifting and lowering of the first slider be driven in sequence, but also after the first slider is lowered to the specified position, the rubber feed wheel can be driven to rotate through the automatic combination of the lifting gear and the transmission idler wheel, thereby completing the automatic loading of the metal sheet.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a variable diameter metal plate winding pipe making device, including an automatic feeding mechanism, a two-stage adaptive downward pressure mechanism, an automatic feed and withdraw mechanism and an extrusion rolling mechanism, the automatic feeding mechanism includes a bottom plate, a feeding assembly and a unloading chute, the unloading chute is arranged on the bottom plate, and the feeding assembly is arranged on the bottom plate.

[0008] As a further preference of the present invention, the feeding assembly includes a feeding chamber, a feeding platform, a metal sheet, and a feeding spring. The feeding chamber is arranged on the bottom plate. Three sides of the top of the feeding chamber are provided with baffles. The feeding platform is fixedly connected to the feeding chamber. The metal sheets are arranged in an array in the feeding chamber. The metal sheets can slide vertically in the feeding chamber. The feeding spring is arranged between the bottom of the feeding chamber and the metal sheets.

[0009] The feeding spring can continuously push the metal sheets upward, enabling the rubber feeding wheel to squeeze against the uppermost metal sheet. Then, when the rubber feeding wheel rotates, it can push the uppermost metal sheet towards the roller body to slide, thus completing the feeding.

[0010] Furthermore, the two-stage adaptive pressing mechanism includes a lifting base, a two-stage lifting component, an adaptive descending control component, and a lifting driving component. The lifting base is arranged on the bottom plate. There is a lifting substrate above the lifting base. The lifting substrate is provided with a slot for avoiding interference. The two-stage lifting component is arranged on the lifting base. The adaptive descending control component is arranged on the two-stage lifting component. The lifting driving component is arranged on the two-stage lifting component.

[0011] The two independent transverse and longitudinal movement mechanisms in the two-stage adaptive pressing mechanism can, under the action of the linkage mechanism, achieve serialized linkage control through the same driving mechanism, enabling the transverse movement and longitudinal movement of the material discharging fork to adapt to each other, and achieving the technical effect of adaptive sequential control without any electronic control module.

[0012] Preferably, the two-stage lifting component includes a lifting guide rail, a first slider, a second slider, a first spring, and a second spring. The lifting guide rail is fixedly connected to the lifting substrate. The first slider and the second slider are both engaged and slidably arranged on the lifting guide rail. The first slider is located above the second slider. The first slider is provided with a plate-shaped convex part. The first spring is arranged between the first slider and the second slider. The second spring is arranged between the second slider and the lifting base.

[0013] Under the elastic force of the first spring and the second spring, the first slider and the second slider tend to rise and reset and separate from each other. Therefore, during the material discharging stage, driven by the driving motor, the first slider and the second slider will first slide upward to a specified position before starting to drive the material discharging fork to move transversely for material discharging.

[0014] As a further preferred embodiment of the present invention, the adaptive descent control component includes a U-shaped spring piece, a friction shoe, a planetary reducer, a lifting gear and a lifting rack. The planetary reducer is provided with a sun gear shaft, an outer gear ring and a planetary carrier output shaft. The planetary carrier output shaft is rotatably arranged in the first slider. The U-shaped spring piece is arranged between the plate-like boss portion and the friction shoe. The friction shoe is in sliding contact with the outer wall of the outer gear ring. The contact portion between the outer gear ring and the friction shoe is sprayed with a friction coating. The lifting gear is fixed to the outer gear ring, and the lifting rack is fixed to the lifting base plate. The lifting gear and the lifting rack are meshed for transmission. A rack slope portion is provided at the lower part of the lifting rack. When the lifting gear moves to the rack slope portion, the meshing relationship between itself and the lifting rack will be temporarily released.

[0015] Since the friction force of the friction shoe on the outer wall of the outer gear ring is greater than the rotational resistance of the planetary carrier output shaft, when the driving motor rotates with the sun gear shaft, the planetary carrier output shaft will rotate first. When the resistance of the planetary carrier output shaft is too large and cannot rotate, the outer gear ring will overcome the friction between itself and the friction shoe and rotate. When the outer gear ring rotates, it can drive the first slider and the second slider to descend through the mutual matching of the lifting gear and the lifting rack. Preferably, the lifting drive assembly includes a motor mounting plate, a drive motor and a coupling, the motor mounting plate is fixedly connected to the side of the first slider, the drive motor is fixedly connected to the motor mounting plate, and the output shaft of the drive motor and the sun gear shaft are connected via a coupling.

[0016] Furthermore, the automatic feeding and withdrawing mechanism includes a front-end lifting component, a transverse transmission component and a feeding component. The front-end lifting component is arranged on a lifting base plate, the transverse transmission component is arranged on the front-end lifting component, and the feeding component is arranged on the feeding component.

[0017] Through the longitudinal movement of the automatic feeding and withdrawing mechanism, the second slider and the shaping roller can be pressed down by the descent of the first slider, thereby achieving the purpose of rolling the plate. Through the lateral movement of the automatic feeding and withdrawing mechanism, the metal tube mounted on the shaping roller can be withdrawn.

[0018] Preferably, the front end lifting assembly includes a T-shaped guide rail, a front end slider, a U-shaped bracket, a lower pressure plate and a lower pressure roller, the T-shaped guide rail is fixedly connected to the lifting base plate, a limit stop block is arranged on the top of the T-shaped guide rail, the front end slider is snap-fitted and slidably arranged on the T-shaped guide rail, the U-shaped bracket is fixedly connected to the front end slider, the lower pressure plate is symmetrically arranged at both ends of the U-shaped bracket, a fork frame part is arranged at the bottom of the lower pressure plate, and the lower pressure roller is rotatably arranged on the fork frame part.

[0019] By lowering the U-shaped bracket, the shaping roller can be rigidly squeezed by the pressing roller, forcing the shaping roller to lower. After lowering, the shaping roller can rotate along with the rotation of the drum body, and the pressing roller can also rotate along with the shaping roller. When withdrawing the material, the pressing roller needs to be separated from the shaping roller under the elastic force of the first spring, and then the metal tube on the shaping roller will be separated by the lateral sliding of the withdrawing fork.

[0020] As a further preferred embodiment of the present invention, the transverse transmission assembly includes a transverse guide rail, a transverse slider, a transmission screw and a material return fork. The transverse guide rail is fixedly connected to the lower pressure plate, the transverse slider is slidably engaged on the transverse guide rail, the transmission screw is rotatably arranged in the U-shaped bracket and the lower pressure plate, one end of the transmission screw is connected to the output shaft of the planetary carrier, and the material return fork is fixedly connected to the bottom of the transverse slider.

[0021] Preferably, the feed assembly comprises an idler wheel bracket, a transmission idler wheel, a feed shaft bracket and a feed wheel shaft, the idler wheel bracket is fixedly connected to the lifting base, the idler wheel bracket is provided with a position sensing contact, the transmission idler wheel is rotatably arranged on the idler wheel bracket, when the lifting gear descends to the ramp portion of the rack, the lifting gear can contact and mesh with the transmission idler wheel, the transmission idler wheel is provided with a position sensing ring, the position sensing ring is provided with a sensing point corresponding to the position sensing contact, the feed shaft bracket is arranged on the feeding platform, the feed wheel shaft is rotatably arranged in the feed shaft bracket, a rubber feed wheel is provided at the middle position of the feed wheel shaft, the rubber feed wheel is in rolling contact with the topmost metal sheet, a transmission gear is provided at one end of the feed wheel shaft, the transmission gear and the transmission idler wheel are meshed for transmission.

[0022] When the lifting gear drops to the lowest position, on the one hand, the lifting gear will separate from the lifting rack and stop descending. At this time, no matter the drive motor continues to rotate or remains stationary, the first slider can maintain its current position; on the other hand, the lifting gear will be combined with the transmission idler wheel. Through the transmission of the transmission idler wheel and the feed wheel shaft, the rubber feed wheel can be driven to rotate, thereby completing the loading.

[0023] When the transmission idler wheel rotates, the number of rotations of the transmission idler wheel can be sensed and controlled through the position sensing ring and the sensing point, which can ensure that the metal sheet is pushed forward enough so that the metal sheet can contact the middle of the drum body and the shaping roller, and can also avoid the second layer of metal sheet being pushed.

[0024] Furthermore, the extrusion and rolling mechanism includes a driving rolling assembly, a shaping roller and a metal tube. The shaping roller is rotatably arranged in the second slider, and the metal tube is wrapped around the outside of the shaping roller. The metal tube is formed by winding a metal sheet. The metal tube can be separated from the shaping roller by sliding a material withdrawal fork. The driving rolling assembly is arranged on the bottom plate.

[0025] Preferably, the driving rolling assembly includes a roller motor, a roller bracket, a roller body and a gear transmission device, the roller motor is arranged on the bottom plate, the roller bracket is arranged on the bottom plate, the roller body is rotatably arranged on the roller bracket, the roller motor and the roller body are transmitted through the gear transmission device, and the outside of the roller body is sprayed with an anti-slip coating.

[0026] Through the continuous rotation of the roller body, on the one hand, it can rotate with the shaping roller and extrude the straight metal sheet through the positional relationship between the shaping roller and the roller body; on the other hand, it can also pull the metal sheet that has contacted the roller body and make it roll into a metal tube along the shaping roller.

[0027] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The metal sheet can be continuously pushed upward by the feeding spring, so that the rubber feeding wheel and the top metal sheet can be squeezed against each other, and then when the rubber feeding wheel rotates, it can push the top metal sheet to slide toward the roller body, thereby completing the feeding.

[0028] (2) The two independent lateral and longitudinal movement mechanisms in the two-stage adaptive downward pressure mechanism can realize serial linkage control through the same driving mechanism under the action of the linkage mechanism, so that the lateral movement and longitudinal movement of the material return fork can adapt to each other, and realize the technical effect of adaptive sequential control without going through any electronic control module.

[0029] (3) Under the elastic force of the first spring and the second spring, the first slider and the second slider have a tendency to rise and reset and separate from each other. Therefore, in the stage of material withdrawal, the first slider and the second slider will first slide upward to the specified position through the drive of the driving motor, and then start to drive the material withdrawal fork to move horizontally to withdraw the material.

[0030] (4) Since the friction force of the friction shoe on the outer wall of the outer gear ring is greater than the rotational resistance of the planetary carrier output shaft, when the drive motor rotates with the sun gear shaft, the planetary carrier output shaft will rotate first. When the resistance of the planetary carrier output shaft is too large and cannot rotate, the outer gear ring will overcome the friction between itself and the friction shoe and rotate. When the outer gear ring rotates, it can drive the first slider and the second slider to descend through the mutual matching of the lifting gear and the lifting rack. (5) Through the longitudinal movement of the automatic feeding and discharging mechanism, the second slider and the shaping roller can be pressed down by the descent of the first slider, thereby achieving the purpose of coiling the sheet. By the transverse movement of the automatic feeding and discharging mechanism, the metal tube sleeved on the shaping roller can be discharged.

[0031] (6) By the descent of the U-shaped bracket, the shaping roller can be rigidly extruded by the pressing roller, forcing the shaping roller to descend. The descended shaping roller can rotate following the rotation of the roller body. At this time, the pressing roller can also rotate to adapt to the shaping roller; during discharging, first, the pressing roller needs to separate from the shaping roller under the elastic force of the first spring, and then the metal tube sleeved on the shaping roller is separated by the transverse sliding of the discharging fork.

[0032] (7) When the lifting gear descends to the lowest position, on the one hand, the lifting gear will separate from the lifting rack and stop descending. At this time, whether the driving motor continues to rotate or remains stationary, the first slider can maintain its current position; on the other hand, at this time, the lifting gear will engage with the transmission idler gear. Through the transmission of the transmission idler gear and the feeding wheel shaft, the rubber feeding wheel can be driven to rotate, thereby completing the feeding.

[0033] (8) After the transmission idler gear rotates, the number of rotations of the transmission idler gear can be sensed and controlled through the position sensing ring and the sensing point. It can not only ensure that the feeding amount of the metal sheet is sufficient so that the metal sheet can contact the middle of the roller body and the shaping roller, but also avoid the situation where the second layer of metal sheet is pushed.

[0034] (9) Through the continuous rotation of the roller body, on the one hand, it can drive the shaping roller to rotate together, and extrude the flat metal sheet through the positional relationship between the shaping roller and the roller body. On the other hand, it can also pull the metal sheet that has contacted the roller body, so that it is wound around the shaping roller into a metal tube. Description of the Drawings

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it is necessary to understand that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0040] like Figure 1 to Figure 13 As shown, the present invention proposes a variable diameter metal plate winding pipe making device, including an automatic feeding mechanism 1, a two-stage adaptive pressing mechanism 2, an automatic feeding and retracting mechanism 3 and an extrusion and rolling mechanism 4, the automatic feeding mechanism 1 includes a bottom plate 5, a feeding assembly 6 and a discharge chute 63, the discharge chute 63 is arranged on the bottom plate 5, and the feeding assembly 6 is arranged on the bottom plate 5.

Baffles 11 are provided on the three top sides of the feeding cabin 7. The feeding platform 8 is fixed to the feeding cabin 7. The metal plate 9 is arranged in an array in the feeding cabin 7. The metal plate 9 can slide vertically in the feeding cabin 7. The feeding spring 10 is arranged between the bottom of the feeding cabin 7 and the metal plate 9.

[0042] The metal sheet 9 can be continuously pushed upward by the feeding spring 10, so that the rubber feeding wheel 55 and the top metal sheet 9 can be squeezed against each other, and then when the rubber feeding wheel 55 rotates, it can push the top metal sheet 9 to slide toward the roller body 62, thereby completing the feeding.

[0043] The extrusion rolling mechanism 4 includes a driving rolling assembly 57, a shaping roller 58 and a metal tube 59. The shaping roller 58 is rotatably arranged in the second slider 19. The metal tube 59 is wrapped around the outside of the shaping roller 58. The metal tube 59 is wound by a metal sheet 9.

[0045] Through the continuous rotation of the roller body 62, on the one hand, it can rotate with the shaping roller 58 and squeeze the straight metal sheet 9 through the positional relationship between the shaping roller 58 and the roller body 62. On the other hand, it can also pull the metal sheet 9 that has contacted the roller body 62 so that it can be wound into a metal tube 59 along the shaping roller 58.

[0046] The two-stage adaptive downward pressure mechanism 2 includes a lifting base 12, a two-stage lifting component 13, an adaptive descent control component 14 and a lifting drive component 15. The lifting base 12 is arranged on the bottom plate 5. A lifting substrate 16 is arranged above the lifting base 12. The lifting substrate 16 is provided with a groove for avoiding position. The two-stage lifting component 13 is arranged on the lifting base 12, the adaptive descent control component 14 is arranged on the two-stage lifting component 13, and the lifting drive component 15 is arranged on the two-stage lifting component 13.

[0047] The two independent lateral and longitudinal movement mechanisms in the two-stage adaptive downward pressure mechanism 2 can realize serialized linkage control through the same driving mechanism under the action of the linkage mechanism, so that the lateral movement and longitudinal movement of the return material fork 65 can adapt to each other, and realize the technical effect of adaptive sequential control without going through any electronic control module.

[0048] The two-stage lifting assembly 13 includes a lifting guide rail 17, a first slider 18, a second slider 19, a first spring 20 and a second spring 21.

The first spring 20 is arranged between the first slider 18 and the second slider 19. The second spring 21 is arranged between the second slider 19 and the lifting base 12.

[0049] Under the elastic force of the first spring 20 and the second spring 21, the first slider 18 and the second slider 19 have a tendency to rise and reset and separate from each other. Therefore, in the material unloading stage, driven by the drive motor 28, the first slider 18 and the second slider 19 will first slide upward to the specified position before starting to drive the unloading fork 65 to move horizontally to unload the material.

[0050] The adaptive descent control component 14 includes a U-shaped spring piece 22, a friction shoe 23, a planetary reducer 24, a lifting gear 25 and a lifting rack 26.

When the lifting gear 25 moves to the rack slope portion 34, the meshing relationship between itself and the lifting rack 26 will be temporarily released.

[0051] Since the friction force of the friction shoe 23 on the outer wall of the outer gear ring 32 is greater than the rotation resistance of the planetary carrier output shaft 33, when the driving motor 28 rotates with the sun gear shaft 31, the planetary carrier output shaft 33 will rotate first. When the resistance of the planetary carrier output shaft 33 is too large and cannot rotate, the outer gear ring 32 will overcome the friction between itself and the friction shoe 23 and rotate.

[0055] By lowering the U-shaped bracket 40, the shaping roller 58 can be rigidly squeezed by the pressing roller 42, forcing the shaping roller 58 to descend. After descending, the shaping roller 58 can rotate along with the rotation of the drum body 62, and at this time, the pressing roller 42 can also rotate and adapt along with the shaping roller 58. When withdrawing the material, the pressing roller 42 first needs to be separated from the shaping roller 58 under the elastic force of the first spring 20, and then the metal tube 59 on the shaping roller 58 will be separated by the lateral sliding of the material withdrawal fork 65.

[0056] The transverse transmission assembly 36 includes a transverse guide rail 43, a transverse slider 44, a transmission screw 45 and a material return fork 65.

[0058] When the lifting gear 25 drops to the lowest position, on the one hand, the lifting gear 25 will separate from the lifting rack 26 and stop descending. At this time, no matter whether the drive motor 28 continues to rotate or remains stationary, the first slider 18 can maintain its current position; on the other hand, at this time, the lifting gear 25 will be combined with the transmission idler wheel 47, and through the transmission of the transmission idler wheel 47 and the feed wheel shaft 49, it can drive the rubber feed wheel 55 to rotate, thereby completing the loading.

[0059] When the transmission idler wheel 47 rotates, the number of rotations of the transmission idler wheel 47 can be sensed and controlled through the position sensing ring 53 and the sensing point 54, which can ensure that the metal sheet 9 is pushed forward enough so that the metal sheet 9 can contact the middle of the drum body 62 and the shaping roller 58, and can also prevent the second layer of metal sheet 9 from being pushed.

[0060] The resistance of the transverse slider 44 sliding on the transverse guide rail 43 is smaller than the friction resistance of the friction shoe 23 on the outer gear ring 32, and the friction resistance of the friction shoe 23 on the outer gear ring 32 is smaller than the elastic force of the first spring 20 and the second spring 21. Therefore, when the drive motor 28 rotates, the transverse slider 44 will first slide to the extreme position close to the lifting base plate 16, and when the transverse slider 44 cannot slide, the outer gear ring 32 and the friction shoe 23 will rotate relative to each other; and in the reversal and reset stage, because the friction resistance of the friction shoe 23 on the outer gear ring 32 is smaller than the elastic force of the first spring 20 and the second spring 21, when the elastic force of the first spring 20 and the second spring 21 is dominant, the rotation of the drive motor 28 will allow the first spring 20 and the second spring 21 to extend; therefore, the first slider 18 will first reset to the top, and then the transverse slider 44 will slide laterally.

[0061] The gear transmission mechanism used in this solution only represents the path of power transmission. In actual use, other suitable transmission forms such as belt transmission, roller transmission, etc. can also be selected according to needs.

[0062] The installation of the shaping roller 58 must be a cantilever structure. Therefore, in order to provide sufficient extrusion force, two downward pressing plates 41 and downward pressing rollers 42 are arranged above the shaping roller 58 for pressing down. According to the strength and thickness of the metal sheet 9, if the strength provided by the single-sided T-shaped guide rail 38 and the front end slider 39 is insufficient, it can also be installed through other structural forms, and the U-shaped bracket 40 can realize the same lifting and lowering movement as in the present embodiment.

[0063] During specific use, the user first needs to press multiple metal sheets 9 into the feed chamber 7. Under the elastic force of the feed spring 10, the top layer of metal sheets 9 will contact and squeeze the rubber feed wheel 55. Since there are baffles 11 on the three upper sides of the feed platform 8, the metal sheets 9 can only slide toward the notch of the baffle 11, that is, in the direction close to the roller body 62, when the rubber feed wheel 55 rotates.

[0064] First, the driving motor 28 is driven, and the sun gear shaft 31 is rotated by the rotation of the driving motor 28. At this time, due to the friction resistance between the friction shoe 23 and the outer gear ring 32, and the sliding resistance of the transverse slider 44 on the transverse guide rail 43 is less than the friction resistance of the friction shoe 23 to the outer gear ring 32, the outer gear ring 32 will remain stationary. At this time, the planetary carrier output shaft 33 rotates with the transmission screw 45. When the transmission screw 45 rotates, the transverse slider 44 slides along the transverse guide rail 43 toward the direction close to the lifting base plate 16. When the lifting base plate 16 slides to the extreme position closest to the lifting base plate 16, the planetary carrier output shaft 33 can no longer rotate. At this time, the outer gear ring 32 will overcome the friction force of the friction shoe 23 and rotate. Since the lifting rack 26 and the lifting gear 25 are meshed, when the outer gear ring 32 rotates with the lifting gear 25, the first slider 18 will descend along the lifting guide rail 17 and compress the first spring 20 and the second spring 21. As the first slider 18 and the second slider 19 approach each other, after the lower pressing roller 42 contacts the shaping roller 58, the first slider 18 and the second slider 19 will be relatively stationary and descend together until the lifting gear 25 moves to the rack ramp portion 34, at which time the lifting gear 25 and the lifting rack 26 are disengaged, and the lifting gear 25 and the transmission idler 47 are engaged. During the process of the lifting gear 25 and the lifting rack 26 being disengaged, the driving motor 28 will not cause the first slider 18 to rise even if it continues to rotate or is stationary. When the shaping roller 58 descends to the bottom limit position, it will contact or will contact the rotating drum body 62.

[0065] After the lifting gear 25 and the transmission idler wheel 47 are combined, as the driving motor 28 continues to rotate, the transmission idler wheel 47 drives the transmission gear 56 and the feed wheel shaft 49 to rotate together, and at the same time drives the rubber feed wheel 55 to rotate. Through the induction of the sensing point 54 and the position sensing contact 52, the rotation angle of the transmission idler wheel 47 can be known and controlled. When the transmission idler wheel 47 rotates a specific angle, that is, the rubber feed wheel 55 drives the metal sheet 9 to enter the junction of the drum body 62 and the shaping roller 58, and before the metal sheet 9 and the rubber feed wheel 55 are separated, the driving motor 28 is turned off; Then the metal sheet 9 will be pulled by the rotating roller body 62 to continue moving, and through the extrusion of the roller body 62 and the shaping roller 58, the metal sheet 9 is wound on the shaping roller 58 to form a metal tube 59. At this time, since the driving motor 28 is stationary, the metal sheet 9 and the rubber feed wheel 55 are relatively sliding.

[0066] After multiple rounds of rolling, the metal tube 59 will fit onto the shaping roller 58, leaving only a seam on the side.

[0067] Then the driving motor 28 reverses. At this time, since the second slider 19 and the U-shaped spring 22 still maintain a large elastic force, the rotation of the driving motor 28 allows the first spring 20 and the second spring 21 to extend when the elastic force of the first spring 20 and the second spring 21 is dominant; therefore, the first slider 18 is first reset to the top, and then the transverse slider 44 slides transversely; After the first slider 18 and the second slider 19 are reset, the pressing roller 42 is also separated from the shaping roller 58. At this time, since the first slider 18 has moved to the top limit position, the lifting gear 25 cannot rotate. Therefore, the rotation of the driving motor 28 will push the transverse slider 44 to slide in the direction away from the lifting base plate 16. At this time, the sliding material return fork 65 can push down the metal tube 59 mounted on the shaping roller 58. The pushed down metal tube 59 slides to a specific position through the unloading chute 63, and then the joint is connected by welding.

[0068] When the diameter of the metal tube 59 needs to be changed, it is only necessary to replace the shaping roller 58 of the corresponding specification and adjust the position of the lifting rack 26 longitudinally.
