[0064] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0065] Reference below Figure 1-Figure 18 The inner supporting mechanism 103 and the tube shaping device 100 according to the embodiment of the present invention are described.

[0066] The inner support mechanism 103 according to the first embodiment of the present invention is used in the tube shaping device 100 and includes an inner support body 20 , wherein the inner support body 20 includes: an inner support frame 21 , an elastic structure 30 and at least one support 40 .

[0067] For example, the inner support frame 21 is strip-shaped, and the tube shaping device 100 includes an extrusion roller structure 101. The inner support frame 21 is passed through the middle of the extrusion roller structure 101 of the tube shaping device 100. The tube material belt can wrap the inner support frame 21 and move along the direction of the inner support frame 21. The tube material belt is extruded and welded when passing through the extrusion roller structure 101, thereby realizing tube forming.

[0068] The elastic structure 30 is disposed on the inner support frame 21. For example, the elastic structure 30 can be a spring. For another example, the elastic structure 30 can be an inflatable bladder 34.

[0069] The elastic structure 30 is connected to the support frame 40. For example, the elastic structure 30 can be a spring, and one end of the spring is welded to the support frame 40, which can make the connection between the elastic structure 30 and the support frame 40 tighter and prevent the elastic structure 30 from falling off and sliding out, thereby affecting the effect of the internal support mechanism 103.

[0070] The support 40 is arranged on the inner support frame 21 and is used to contact the pipe material belt. At least one support 40 is connected to the elastic structure 30 so that at least one support 40 can move. By connecting at least one support 40 to the elastic structure 30, the support 40 can be elastically moved relative to the inner support frame 21. By making the support 40 contact the pipe material belt, when the pipe material belt has a tendency to collapse or sink, the support 40 can be pressed against the pipe material belt and can move adjustably, thereby reducing the contour gap, so that the material belt can align the edges to be welded during operation, and ensure a good welding effect. The inner support mechanism 103 may include one support 40, or it may include multiple supports 40. For example, the inner support mechanism 103 includes two supports 40, and the two supports 40 are arranged above and below the inner support frame 21, and the two supports 40 are respectively in contact with the upper edge and the lower edge of the pipe material belt from the inside.

[0071] According to the internal support mechanism 103 of the embodiment of the present invention, the internal support mechanism 103 includes an internal support body 20, and the internal support body 20 includes an internal support frame 21, an elastic structure 30 and at least one support 40. By connecting at least one support 40 with the elastic structure 30 so that at least one support 40 is movable, the support 40 of the internal support mechanism 103 can be elastically offset against the material strip. The support 40 of the internal support mechanism 103 can be adjusted to compensate for the contour gap caused by the cumulative errors caused by material strip feeding, mold processing and assembly, so that the edges to be welded can be kept aligned during the operation of the material strip, thereby ensuring the welding effect.

[0072] According to some embodiments of the present invention, referring to Figure 2-Figure 5At least one support 40 includes a wheel bracket 41 and a roller 42. The wheel bracket 41 is provided on the inner support frame 21, and the roller 42 is rotatably mounted on the wheel bracket 41. The roller 42 is used to contact the tube material belt. By providing the wheel bracket 41 on the inner support frame 21 and rotatably mounting the roller 42 on the wheel bracket 41, the connection between the roller 42 and the inner support frame 21 can be made more stable, and the roller 42 can be prevented from falling off and affecting the effect of the inner support mechanism 103. By making at least one support 40 include the wheel bracket 41 and the roller 42, the contact friction between the support 40 and the tube material belt can be rolling friction. In the process of the tube material belt feeding and moving along the length direction of the inner support frame 21 (for example, the e1 direction in the figure), the friction between the support 40 and the tube material belt is reduced, so that the feeding of the tube material belt is smoother, and the wear and damage to the tube material belt can be reduced.

[0073] According to some embodiments of the present invention, referring to Figure 14-Figure 18 At least one support 40 is detachably connected to the inner support frame 21. By making at least one support 40 detachably connected to the support frame 40, the replacement and maintenance of the support 40 can be made more convenient.

[0074] According to some embodiments of the present invention, referring to Figure 2 , there are multiple supports 40, and the multiple supports 40 include an upper support 43 and a lower support 47. The upper support 43 is arranged on the upper side of the inner support frame 21 and is used to contact the top of the tube material belt. The lower support 47 is arranged on the lower side of the inner support frame 21 and is used to contact the bottom of the tube material belt. The length direction of the tube material belt intersects with the up-down direction. By making the multiple supports 40 include an upper support 43 and a lower support 47, and making the upper support 43 arranged on the upper side of the inner support frame 21 and being used to contact the top of the tube material belt, and the lower support 47 arranged on the lower side of the inner support frame 21 and being used to contact the bottom of the tube material belt, the supports 40 can more fully support the tube material belt upward 43 and downward 47, and ensure that the distance between the upper and lower ends of the tube material belt is within a set range.

[0075] According to some embodiments of the present invention, referring to Figure 2 There are multiple upper supports 43, and the multiple upper supports 43 are arranged along the length direction of the tube material strip. By having multiple upper supports 43 and arranging the multiple upper supports 43 along the length direction of the tube material strip, the material strip can be continuously limited by the upper supports 43 during the feeding process, so that the upper supports 43 have a more effective effect, thereby more fully ensuring a good welding effect.

[0076] According to some embodiments of the present invention, referring to Figure 2There are multiple lower supports 47, and the multiple lower supports 47 are arranged along the length direction of the tube material strip. By having multiple lower supports 47 and arranging the multiple lower supports 47 along the length direction of the tube material strip, the material strip can be continuously limited by the lower supports 47 during the feeding process, so that the effect of the lower supports 47 is more sufficient, thereby more fully ensuring a good welding effect.

[0077] According to some embodiments of the present invention, referring to Fig.14 and Fig.15 The upper support 43 includes an upper wheel bracket 41 and an upper roller 46. The upper wheel bracket 41 is provided on the inner support frame 21. The upper roller 46 is rotatably mounted on the upper wheel bracket 41. The upper roller 46 is used to contact the tube material belt. By providing the upper wheel bracket 41 on the inner support frame 21 and rotatably mounting the upper roller 46 on the upper wheel bracket 41, the upper roller 46 can be more stably connected to the inner support frame 21, and the upper roller 46 can be prevented from falling off to affect the effect of the inner support mechanism 103. By making the upper support 43 include the upper wheel bracket 41 and the upper roller 46, and the upper roller 46 is used to contact the tube material belt, the contact friction between the support 40 and the tube material belt can be rolling friction. In the process of feeding the tube material belt along the length direction of the inner support frame 21, the friction between the support 40 and the tube material belt is reduced, so that the feeding of the tube material belt is smoother, and the wear and damage to the tube material belt can be reduced.

[0078] According to some embodiments of the present invention, referring to Fig.16 and Fig.17 The lower support 47 includes a lower wheel bracket 49 and a lower roller 50. The lower wheel bracket 49 is provided on the inner support frame 21. The lower roller 50 is rotatably mounted on the lower wheel bracket 49. The lower roller 50 is used to contact the pipe material belt. By providing the lower wheel bracket 49 on the inner support frame 21 and rotatably mounting the lower roller 50 on the lower wheel bracket 49, the connection between the lower roller 50 and the inner support frame 21 can be made more stable, and the lower roller 50 can be prevented from falling off and affecting the effect of the inner support mechanism 103. By making the lower support 47 include the lower wheel bracket 49 and the lower roller 50, and the lower roller 50 is used to contact the pipe material belt, the contact friction between the support 40 and the pipe material belt can be made rolling friction. In the process of feeding the pipe material belt along the length direction of the inner support frame 21, the friction between the support 40 and the pipe material belt is reduced, so that the feeding of the pipe material belt is smoother, and the wear and damage to the pipe material belt can be reduced.

[0079] According to some embodiments of the present invention, referring to Figure 2, there are multiple upper supports 43, and the multiple upper supports 43 are arranged along the length direction of the tube material belt, and the upper wheel brackets 41 of the multiple upper supports 43 are connected as one. By having multiple upper supports 43 and arranging the multiple upper supports 43 along the length direction of the tube material belt, the material belt can be continuously limited by the upper supports 43 during the feeding process, so that the effect of the upper supports 43 is more sufficient, thereby more fully ensuring a good welding effect. By connecting the upper wheel brackets 41 of the multiple upper supports 43 as one, the connection between the multiple upper wheel brackets 41 can be tightened, avoiding the connection failure between the multiple upper rollers 46, resulting in the change of the relative position between the multiple upper rollers 46, and reducing the welding effect of the tube material belt.

[0080] According to some embodiments of the present invention, referring to Figure 2 The upper wheel brackets 41 of the plurality of upper supports 43 are integrally formed. By integrally forming the upper wheel brackets 41 of the plurality of upper supports 43, the connection between the plurality of upper supports 43 can be made tighter, and the relative position between the plurality of upper wheels is prevented from changing due to connection failure between the plurality of upper wheels, thereby reducing the welding effect of the pipe strip.

[0081] According to some embodiments of the present invention, referring to Fig.15 The elastic structure 30 includes a first spring 31, and the upper support 43 is connected to the inner support frame 21 through the first spring 31. By connecting the upper support 43 to the inner support frame 21 through the first spring 31, the upper roller 46 and the inner support frame 21 can be elastically moved up and down, so that the upper roller 46 can elastically abut against the pipe belt, and adaptively ensure that the edges to be welded are kept aligned during the operation of the pipe belt.

[0082] According to some embodiments of the present invention, referring to Fig.17 The elastic structure 30 includes a second spring 32, and the lower support 47 is connected to the inner support frame 21 through the second spring 32. By connecting the lower support 47 to the inner support frame 21 through the first spring 31, the lower roller 50 and the inner support frame 21 can be elastically moved up and down, so that the lower roller 50 can elastically abut against the pipe belt, adaptively ensuring that the edges to be welded are aligned during the operation of the pipe belt.

[0083] According to some embodiments of the present invention, referring to Fig.15 The inner support frame 21 is provided with a first guide rod 22 extending in the up-down direction, the first spring 31 is sleeved on the outer peripheral side of the first guide rod 22, the upper support 43 is formed with a first guide hole 44, and the first guide rod 22 is passed through the first guide hole 44. By providing the first guide rod 22 extending in the up-down direction on the inner support frame 21, forming the first guide hole 44 on the upper support 43, and allowing the first guide rod 22 to pass through the first guide hole 44, the first guide hole 44 can guide and limit the first guide rod 22, so that the upper support 43 can move more stably in the up-down direction.

[0084] For example, refer to Fig.15 The upper support 43 includes an upper wheel bracket 41 and an upper roller 46. The upper wheel bracket 41 is arranged on the inner support frame 21. The upper roller 46 is rotatably installed on the upper wheel bracket 41. The upper wheel bracket 41 is provided with a first guide hole 44. The first guide rod 22 is penetrated by the first guide hole 44.

[0085] According to some embodiments of the present invention, referring to Fig.17 The inner support frame 21 is provided with a second guide rod 24 extending in the up-down direction, the second spring 32 is sleeved on the outer peripheral side of the second guide rod 24, the lower support 47 is formed with a second guide hole 48, and the second guide rod 24 is passed through the second guide hole 48. By providing the second guide rod 24 extending in the up-down direction on the inner support frame 21, forming the second guide hole 48 on the lower support 47, and passing the second guide rod 24 through the second guide hole 48, the second guide hole 48 can guide and limit the second guide rod 24, so that the lower support 47 can move more stably in the up-down direction.

[0086] For example, refer to Fig.17 The lower support 47 includes a lower wheel bracket 49 and a lower roller 50. The lower wheel bracket 49 is arranged on the inner support frame 21. The lower roller 50 is rotatably mounted on the lower wheel bracket 49. A second guide hole 48 is formed on the lower wheel bracket 49. The second guide rod 24 is penetrated by the second guide hole 48.

[0087] According to some embodiments of the present invention, referring to Fig.15 The upper end of the first guide rod 22 is provided with a first limiting protrusion 23, and the first limiting protrusion 23 is located on the upper side of the upper support 43 to limit the upper support 43. By providing the first limiting protrusion 23 on the upper end of the first guide rod 22, the upper roller 46 can support the tube strip 40 within a certain range, preventing the first guide rod 22 from moving upward too much and driving the tube strip to move upward too much beyond the limited range to affect the welding effect.

[0088] According to some embodiments of the present invention, referring to Fig.17 The second guide rod 24 has a second limiting protrusion 25 at its lower end, and the second limiting protrusion 25 is located at the lower side of the lower support 47 to limit the lower support 47. By providing the second limiting protrusion 25 at the upper end of the second guide rod 24, the support 40 of the tube strip by the lower roller 50 can be within a certain range, preventing the second guide rod 24 from moving too much downward and causing the tube strip to move too much downward beyond the limited range to affect the welding effect.

[0089] According to some embodiments of the present invention, referring to Figure 4 and Figure 5, the multiple supports 40 include a side support 52, and in the up-down direction, the side support 52 is located between the highest position of the upper support 43 and the lowest position of the lower support 47, and the side support 52 is used to contact the side of the pipe strip. By making the multiple supports 40 include the side support 52, and making the side support 52 contact the side of the pipe strip, the side support 52 can be made to elastically support the side of the pipe strip, thereby preventing the side of the pipe strip from collapsing or sinking and affecting the welding effect. By making the side support 52 located between the highest position of the upper support 43 and the lowest position of the lower support 47, the side support 52 can be prevented from affecting the highest position and the lowest position, thereby preventing the support 40 structure from causing the pipe strip to move upward or downward too much beyond the limited range and affecting the welding effect.

[0090] According to some embodiments of the present invention, referring to Figure 2 , there are multiple side supports 52, and the multiple side supports 52 are divided into at least one side support group 51. When there are multiple side support groups 51, the multiple side support groups 51 are arranged along the length direction of the tube material strip, and each side support group 51 includes two side supports 52 opposite to each other along the width direction of the inner support frame 21 (for example, the e2 direction in the figure), and the width direction of the inner support frame 21 intersects with the up-down direction and the length direction of the tube material strip. By dividing the multiple side supports 52 into at least one side support group 51, and each side support group 51 includes two side supports 52 opposite to each other along the width direction of the inner support frame 21, the side support group 51 can adaptively adjust and compensate the tube material strip from the width direction of the inner support frame 21 to ensure that the strip forming profile meets the set requirements. By arranging the multiple side support groups 51 along the length direction of the tube material strip, the strip can be continuously limited by the side support 52 from the width direction of the inner support frame 21 during the feeding process, so that the effect of the side support 52 is more sufficient, thereby more fully ensuring a good welding effect.

[0091] For example, the inner support mechanism 103 includes a lower support 47, and the side support group 51 includes a first side support group 51 and a second side support group 51. The lower support 47 is arranged directly below the first side support group 51, and the lower support 47 is not arranged directly below the second side support group 51, so that the length of the first side support group 51 in the vertical direction can be shorter than the length of the second side support group 51 in the vertical direction. In this way, the length of the inner support mechanism 103 in the vertical direction can be equal, and the supporting force provided by the inner support mechanism 103 can be more uniform.

[0092] According to some embodiments of the present invention, referring to Figure 5The elastic structure 30 includes a third spring 33, and the inner support frame 21 has a mounting cavity 26. The third spring 33 is located in the mounting cavity 26, and the two side supports 52 in each side support group 51 are connected by the third spring 33. By making the elastic structure 30 include the third spring 33, and the two side supports 52 in each side support group 51 are connected by the third spring 33, the two side supports 52 in each side support group 51 can be elastically moved, so as to limit the support 40 of the pipe material strip from the width direction of the inner support frame 21, and fully ensure a good welding effect.

[0093] According to some embodiments of the present invention, referring to Figure 5 The side support 52 includes a side support seat 53 and a side support roller 54. The two side support seats 53 in each side support group 51 are connected by a third spring 33. The side support roller 54 is rotatably arranged on the side support seat 53. The side support roller 54 is used to contact the side of the tube material belt. By making the side support 52 include the side support roller 54 and making the side support roller 54 contact the side of the tube material belt, the contact friction between the side support 52 and the tube material belt can be made rolling friction. In the process of the feeding of the tube material belt moving along the length direction of the inner support frame 21, the friction between the side support 52 and the tube material belt is reduced, so that the feeding of the tube material belt is smoother.

[0094] According to some embodiments of the present invention, referring to Figure 5 The inner support frame 21 is provided with a guide pin 27 extending in the width direction of the inner support frame 21, and the side support 52 is provided with a third guide hole 55, and the guide pin 27 is passed through the third guide holes 55 on the two side supports 52 in the same side support group 51. By passing the guide pin 27 through the third guide holes 55 on the two side supports 52 in the same side support group 51, the guide pin 27 can guide and position the two side supports 52 in the same side support group 51, so that the two side supports 52 in the same side support group 51 can stably move along the axial direction of the third guide hole 55.

[0095] For example, the side support 52 includes a side support seat 53 and a side support roller 54, the side support seat 53 is provided with a third guide hole 55, and the guide pin shaft 27 passes through the third guide holes 55 on the two side support seats 53 of the two side supports 52 in the same group of side support groups 51.

[0096] For example, two guide pins 27 are provided in the same group of side support groups 51, and the two guide pins 27 are arranged at intervals in the up and down directions. Two third guide holes 55 are respectively provided on the two side supports 52 in the same group of side support groups 51, and the two guide pins 27 respectively and sequentially pass through the two third guide holes 55 on the two side supports 52 in the same group of side support groups 51.

[0097] According to some embodiments of the present invention, referring to Fig.18 The inner wall of the installation cavity 26 forms a limiting groove 28, and a limiting plate 56 is provided on the side support 52. The limiting plate 56 is accommodated in the limiting groove 28 to limit the side support 52 in the width direction of the inner support frame 21. By accommodating the limiting plate 56 in the limiting groove 28, the support 40 of the pipe strip by the side support 52 can be limited within a certain range, preventing the side support 52 from being displaced too much to both sides and squeezing the two sides of the pipe strip to move too much beyond the limited range, causing the pipe strip to be deformed and affecting the welding effect.

[0098] According to some embodiments of the present invention, referring to Figure 9-11 The elastic structure 30 includes a skin bag 34, the inner support frame 21 is connected to the outer surface of the skin bag 34, and the upper support 43 and the lower support 47 are connected to the inner support frame 21. By making the elastic structure 30 include the skin bag 34 and making the inner support frame 21 connected to the outer surface of the skin bag 34, the inner support frame 21 can be relatively able to make the inner support mechanism 103 to achieve elastic support 40 for the pipe material belt, so that the inner support mechanism 103 can adjustably compensate for the contour gap, so that the edges to be welded are kept aligned during the feeding process of the pipe material belt, thereby ensuring the welding effect.

[0099] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 A cooling flow path 60 is provided in the support 40 corresponding to the welding position of the tube material strip, and a liquid inlet 61 and a liquid outlet 62 connected to the cooling flow path 60 are formed on the support 40. Since the temperature at the welding position is high, thermal breakdown may occur in the product. By providing a cooling flow path 60 in the support 40 corresponding to the welding position of the tube material strip, the temperature at the welding position can be reduced, and the risk of thermal breakdown of the product can be reduced. For example, the welding method is laser welding, and the heat at the welding position is relatively concentrated and the temperature is relatively high.

[0100] For example, refer to Figure 7 The support 40 corresponding to the welding position of the tube strip is an upper support 43. The upper support 43 includes an upper wheel bracket 41 and an upper roller 46. The upper wheel bracket 41 is arranged on the inner support frame 21. There are multiple upper supports 43. The multiple upper supports 43 are arranged along the length direction of the tube strip. The upper wheel brackets 41 of the multiple upper supports 43 are integrally formed, and the cooling flow path 60 is arranged in the upper wheel bracket 41.

[0101] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 At least part of the cooling channel 60 extends along the length direction of the pipe strip. By extending at least part of the cooling channel 60 along the length direction of the pipe strip, the pipe strip can be continuously cooled by the cooling channel 60 during the feeding or discharging process, so that the cooling channel 60 can function more fully.

[0102] According to some embodiments of the present invention, referring to Figure 7 In the length direction of the tube strip, the liquid inlet 61 and the liquid outlet 62 are located on the same side of the support 40. By locating the liquid inlet 61 and the liquid outlet 62 on the same side of the support 40, it is more convenient to connect the cooling channel 60 with the liquid inlet pipe and the liquid outlet pipe.

[0103] According to some embodiments of the present invention, referring to Figure 1 The internal support mechanism 103 also includes: a mounting plate 10 and a connecting rod 11, the connecting rod 11 extends along the length direction of the tube material belt, the mounting plate 10 and the internal support body 20 are connected at both ends of the length direction of the connecting rod 11, and the mounting plate 10 is used to install the internal support mechanism 103. By making the internal support structure include the mounting plate 10, and making the mounting plate 10 used to install the internal support mechanism 103, the internal support mechanism 103 can be fully fixed. For example, the mounting plate 10 is connected to the internal support mounting seat 102. By making the internal support mechanism 103 include a connecting rod, and making the mounting plate 10 and the internal support body 20 connected at both ends of the length direction of the connecting rod 11, sufficient space can be provided for feeding or discharging the tube material belt, avoiding the interference of the mounting plate 10 on the tube material belt during feeding or discharging.
