[0002] At present, the installation and connection of the stainless steel chimney port adopts an inlaid non-complex process, which has poor matching accuracy, and the firmness, strength and sealing properties cannot meet the requirements. Therefore, in order to improve the connection firmness between the stainless steel chimney port and the equipment interface, the stainless steel chimney port needs to be flanging. However, in the prior art, the flanging of the stainless steel chimney port is usually done by hard flanging, that is, by manual hammering or manual extrusion to complete the flanging process. This method is not only time-consuming and labor-intensive, but also has low efficiency and high labor intensity, and the quality of the processed metal tube cannot be guaranteed. Summary of the invention

[0003] In view of the deficiencies in the prior art, an object of the present invention is to provide a flanging machine for stainless steel chimney processing, which can achieve the effect of automatic flanging of a metal tube.

[0008] The flanging device includes a flanging wheel and a driving device. The flanging wheel is movably arranged on the frame and can move in the radial direction of the metal tube to be flanging. The driving device is used to drive the movement of the flanging wheel so that the flanging wheel moves along the radial direction of the metal tube to be flanging rotated by the rotating device and from the inside to the outside of the metal tube to be flanging for external flanging, or moves along the radial direction of the metal tube to be flanging rotated by the rotating device and from the outside to the inside of the metal tube to be flanging for internal flanging.

[0009] Furthermore, the rotating device includes a first rotating wheel and a second rotating wheel which are relatively arranged on the frame and rotate synchronously. The first rotating wheel and the second rotating wheel have the same direction of rotation. The thick wall of the metal cylinder to be flanged is pressed and fitted by the first rotating wheel and the second rotating wheel so that it is driven to rotate under the rotational force of the first rotating wheel and the second rotating wheel.

[0010] Furthermore, a first protrusion is arranged on the circumferential surface of the first rotating wheel along its circumference, and a first recessed portion matched with the first protrusion is arranged on the second rotating wheel. The second rotating wheel can also be movably arranged on the frame and can move in a direction close to the first rotating wheel, so that the diameter of the port to be flanging of the rotating metal cylinder can be expanded to form a bell mouth under the action of the first recessed portion and the first protrusion.

[0011] Furthermore, a second protrusion is provided on the circumferential surface of the first rotating wheel along its circumferential direction, the second protrusion is spaced apart from the first protrusion, and a second recess matched with the second protrusion is provided on the second rotating wheel.

[0012] Furthermore, the present invention also includes a moving device, and the moving device is used to drive the movement of the second rotating wheel.

DETAILED DESCRIPTION

[0029] Below, the present invention is described in priority in conjunction with the accompanying drawings and specific implementation methods.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internally connected between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Implementation method:

[0033] See also Figure 1-8 The present invention shows a flanging machine for stainless steel chimney processing, including a frame 1, a rotating device 2 and a flanging device 3. The rotating device 2 is rotatably arranged on the frame 1, and is used to drive the metal tube to be flanging to rotate; the flanging device 3 includes a flanging wheel 30 and a driving device 31. The flanging wheel 30 is movably arranged on the frame 1 and can move in the radial direction of the metal tube to be flanging. The driving device 31 is used to drive the movement of the flanging wheel 30, so that the flanging wheel 30 moves along the radial direction of the metal tube to be flanging rotated by the rotating device 2 and from the inside of the metal tube to be flanging to the outside for external flanging, or moves along the radial direction of the metal tube to be flanging rotated by the rotating device 2 and from the outside of the metal tube to be flanging to the inside for internal flanging. When the flanging machine of the present invention is in use, the metal tube to be flanging is rotated by the rotating device 2. Based on the metal tube to be flanging (stainless steel chimney tube section) being in a rotating state, the flanging wheel 30 is driven by the driving device 31 to move along the radial direction of the metal tube to be flanging and from the inside to the outside of the metal tube to be flanging for external flanging, or along the radial direction of the metal tube to be flanging and from the outside to the inside of the metal tube to be flanging for internal flanging, thereby achieving an automatic flanging effect.

[0034] Those skilled in the art can understand that, when the present invention is applied to external flanging, the original position of the flanging wheel 30 is inside the metal cylinder to be flanging, and the flanging wheel 30 is located at a preset position of the port to be flanging of the metal cylinder, and is driven by the driving device 31 to move from the inside to the outside along the radial direction of the metal cylinder, thereby realizing the external flanging of the metal cylinder; when the present invention is applied to internal flanging, the original position of the flanging wheel 30 is outside the metal cylinder to be flanging, and the flanging wheel 30 is located at a preset position of the port to be flanging of the metal cylinder, and is driven by the driving device 31 to move from the outside to the inside along the radial direction of the metal cylinder, thereby realizing the internal flanging of the metal cylinder.

[0035] In this embodiment, a panel 10 is fixedly provided at the top of the frame 1, and a first waist-shaped hole 100 is provided on the panel 10, and the first waist-shaped hole 100 passes through the upper and lower parts of the panel 10. The rotating device 2 includes a first rotating wheel 20 and a second rotating wheel 21 which are relatively arranged on the frame 1 and can rotate synchronously. The first rotating wheel 20 is rotatably arranged on the frame 1 through a first rotating shaft 201 and a first belt seat bearing 203, and the second rotating wheel 21 is rotatably arranged on the frame 1 through a second rotating shaft 211 and a second belt seat bearing 213. One end of the first rotating shaft 201 passes through the first waist-shaped hole 100, and one end of the second rotating shaft also passes through the above-mentioned first waist-shaped hole 100. The center hole of the first rotating wheel 20 is key-connected with one end of the first rotating shaft 201 passing through the first waist-shaped hole 100, and the center hole of the second rotating wheel 21 is also key-connected with one end passing through the first waist-shaped hole 100. Of course, the bottom of the first rotating wheel 20 and the second rotating wheel 21 do not conflict with the above-mentioned panel 10. In addition, there is a gap between the first rotating wheel 20 and the second rotating wheel 21 for driving the metal tube to be flanging to rotate. It can be seen that the steering settings of the first rotating wheel 20 and the second rotating wheel 21 must be the same. In this way, when the thick wall of the metal tube to be flanging is pressed by the first rotating wheel 20 and the second rotating wheel 21, that is, the outer wall of the metal tube to be flanging is pressed by the circumferential surface of the first rotating wheel 20, and the inner wall of the metal tube to be flanging is pressed by the circumferential surface of the second rotating wheel 21, the metal tube to be flanging can be driven to rotate under the rotational force of the first rotating wheel 20 and the second rotating wheel 21, thereby achieving the effect of rotating the metal tube to be flanging. Of course, it can be understood by those skilled in the art that the metal tube to be flanging does not conflict with the panel 10 during the rotation process.

[0036] In this embodiment, a first protrusion 200 is arranged on the circumferential surface of the first rotating wheel 20 along its circumferential direction, and a first recessed portion 210 adapted to the first protrusion 200 is arranged on the second rotating wheel 21, that is, a first recessed portion 210 is also arranged on the circumferential surface of the second rotating wheel 21 along its circumferential direction, and the first recessed portion 210 corresponds to the position of the first protrusion 200 and can cooperate with the first protrusion 200. On this basis, the second rotating wheel 21 can also be movably arranged on the frame 1 and can move in a direction close to the first rotating wheel 20, so that the caliber of the end to be flanging of the rotating metal cylinder can be expanded to form a bell mouth under the action of the first recessed portion 210 and the first protrusion 200. Since the first protrusion 200 is located on the outer wall of the metal tube to be flanged and close to the position of the end to be flanged of the metal tube to be flanged, and the first recessed portion 210 is located on the inner wall of the metal tube to be flanged and close to the position of the end to be flanged of the metal tube to be flanged and corresponds to the first protrusion 200, when the metal tube to be flanged is rotated under the rotational force of the first wheel 20 and the second wheel 21, when the second wheel 21 is moved toward the direction close to the first wheel 20, the metal tube to be flanged can expand the diameter of the end to be flanged of the metal tube to be flanged under the cooperation of the first protrusion 200 and the first recessed portion 210, so that it can expand to form a bell mouth.

[0037] It is worth mentioning that when the diameter of the port to be flanging of the metal cylinder forms a trumpet-shaped state, the flanging wheel 30 located in the metal cylinder and close to the port to be flanging is driven by the driving device 31 to move along the radial direction of the metal cylinder to be flanging and from the inside of the metal cylinder to be flanging to the outside for external flanging, so that the expanded metal wall can be quickly flanging outward, thereby achieving the effect of rapid flanging, and the flanging effect is better.

[0038] In this embodiment, a second protrusion 202 is further provided on the circumferential surface of the first rotating wheel 20 along its circumferential direction, and the second protrusion 202 is spaced apart from the first protrusion 200, and a second recess 212 is provided on the second rotating wheel 21 to match the second protrusion 202. In other words, it can be understood that a second recess 212 is also provided on the circumferential surface of the second rotating wheel 21, and the second recess 212 is also provided in the circumferential direction of the second rotating wheel 21 and can be matched with the second protrusion 202 on the first rotating wheel 20, and the second protrusion 202 is an annular protrusion, and the second recess 212 is an annular groove. It can be seen that when the metal cylinder to be flanged is rotating under the rotational force of the first rotating wheel 20 and the second rotating wheel 21, when the second rotating wheel 21 is moved toward the direction close to the first rotating wheel 20, the metal cylinder to be flanged can form reinforcing ribs on the rotating metal cylinder under the cooperation of the annular protrusion and the annular groove, thereby achieving the effect of strengthening the rigidity of the metal cylinder (stainless steel chimney section). Of course, for those skilled in the art, by reasonably changing the structure of the second protrusion 202 and the second recessed portion 212 according to actual needs, it should also fall within the protection scope of the present invention.

[0039] The present invention also includes a moving device 5, which is arranged at the bottom of the panel 10 and is used to drive the movement of the second rotating wheel 21. Since the second rotating wheel 21 is movably arranged on the frame 1, and the first rotating wheel 20 is not movable, the above-mentioned first belt seat bearing 203 is fixed on the frame 1, and the above-mentioned second belt seat bearing 213 is fixed on the moving device 5. In this way, the movement of the second belt seat bearing 213 is driven by the moving device 5, thereby driving the second rotating shaft 211 to move in the first waist-shaped hole 100, thereby achieving the effect of moving the second rotating wheel 21 on the second rotating shaft 211.

[0040] Specifically, the moving device 5 includes a guide device 52, a moving member 51 and a power source 50; wherein the guide device 52 is arranged on the frame 1 and arranged along the movable direction of the second rotating wheel 21; the moving member 51 is used to connect the above-mentioned second seat bearing 213, of course, the moving member 51 is movably arranged on the guide device 52 and its movable direction is the same as the movable direction of the second rotating wheel 21; the power source 50 is fixed on the frame 1, and is used to drive the movement of the moving member 51. It can be seen that the moving member 51 is driven by the power source 50 to move along the guide device 52, thereby driving the second seat bearing 213 to move, and the second seat bearing 213 is used to fix the second rotating shaft 211, so the movement of the second seat bearing 213 can drive the movement of the second rotating shaft 211, and then drive the movement of the second rotating wheel 21. The power source 50 of the present embodiment is preferably a hydraulic cylinder. Compared with other power sources (such as a pneumatic cylinder), the cylinder-driven movable member 51 may rebound due to the effect of air pressure when moving along the guide device 52. Therefore, the movement of the second rotating wheel 21 driven by the hydraulic cylinder can improve the stability of its movement.

[0041] Of course, in other embodiments, the power source 50 of the mobile device 5 may also be other power sources 50, such as a cylinder or an electric push rod, etc. Therefore, for those skilled in the art, by reasonably changing the power source 50 of the mobile device 5, it should also fall within the protection scope of the present invention.

[0042] In this embodiment, the guide device 52 includes a first guide assembly and a second guide assembly. The first guide assembly is arranged on the frame 1 and is in the same movable direction as the second rotating wheel 21. The first end of the movable member 51 is movably arranged on the first guide assembly. Taking the rotation axis of the second rotating shaft 211 as a reference, the second guide assembly is arranged on the frame 1 and is symmetrically arranged with the first guide assembly. The second end of the movable member 51 is movably arranged on the second guide assembly. That is, it can be understood that by movably arranging one end of the movable member 51 on the first guide assembly and movably arranging the other end of the movable member 51 on the second guide assembly, the stability of the movable member 51 moving along the first guide assembly and the second guide assembly under the drive of the hydraulic cylinder can be improved.

[0043] In this embodiment, the first guide assembly includes a first guide shaft 520 and a second guide shaft 521, which are arranged relative to each other along the rotation axis of the rotating device 2, and the first side of the movable member 51 is slidably connected to the first guide shaft 520, and the second side of the movable member 51 is slidably connected to the second guide shaft 521; the second guide assembly includes a third guide shaft 522 and a fourth guide shaft 523, the third guide shaft 522 is arranged relative to the first guide shaft 520, and the fourth guide shaft 523 is arranged relative to the second guide shaft 521, the first side of the movable member 51 is also slidably connected to the third guide shaft 522, and the second side of the movable member 51 is also slidably connected to the fourth guide shaft 523. That is to say, it can be understood that the second seat bearing 213 is located between the first guide shaft 520 and the second guide shaft 521 and also between the third guide shaft 522 and the fourth guide shaft 523. When the hydraulic cylinder drives the movable member 51 to drive the second rotating wheel 21 to move, the movable member 51 moves stably under the action of the first guide shaft 520, the second guide shaft 521, the third guide shaft 522 and the fourth guide shaft 523, thereby further improving the stability of the movement of the second rotating wheel 21.

[0044] Of course, a hydraulic oil circuit system 12 is also provided on the frame 1 of the flanging machine of the present invention, and the hydraulic oil circuit system controls the above-mentioned hydraulic cylinder so that the hydraulic cylinder can better drive the movement of the moving part 51.

[0045] In this embodiment, the driving device 31 includes a first sliding device and a first driving member 312. The first sliding device is fixed to the frame 1 through the mounting plate 4 and is located between the panel 10 and the moving device 5. Of course, in order to prevent the mounting plate 4 from interfering with the movement of the second rotating shaft 211, a second waist-shaped hole 40 is provided on the mounting plate 4. The second waist-shaped hole 40 has the same length and the same setting direction as the first waist-shaped hole 100. The second rotating shaft 211 can move in the second waist-shaped hole 40 through the second waist-shaped hole 40. Among them, the first sliding device includes a first mounting seat 310 and a first sliding block 311. The first mounting seat 310 is fixed on the upper surface of the mounting plate 4. The first sliding block 311 is slidably connected to the first mounting seat 310 and can move along the radial direction of the metal pass to be flanging. The flanging wheel 30 can be rotatably arranged on the first sliding block 311. The first driving member 312 drives the first sliding block 311 to move along the radial direction of the metal pass to be flanging to achieve the purpose of moving the flanging wheel 30. The flanging wheel 30 is rotatably arranged on the first sliding block 311, so when the flanging wheel 30 contacts the thick wall of the metal tube to be flanged, the flanging wheel 30 also rotates with the rotational force of the metal tube to be flanged, thereby achieving a better flanging effect. In addition, the driving device 31 of this embodiment is also preferably a hydraulic cylinder.

[0046] Of course, in other embodiments, the first driving member 312 may also use other driving structures, such as a cylinder or an electric push rod, etc. Therefore, for those skilled in the art, by reasonably changing the first driving member 312, it should also fall within the protection scope of the present invention.

[0047] On the basis of the above structure, the present invention further includes a power device 8, which is used to drive the rotation of the first rotating shaft 201 and the second rotating shaft 211, thereby driving the rotation of the first rotating wheel 20 and the second rotating wheel 21. Since the rotation directions of the first rotating wheel 20 and the second rotating wheel 21 are the same, that is, they rotate clockwise or counterclockwise at the same time, in order to save the number of power devices 8, the present invention also includes a transmission device 6, through which the first rotating wheel 20 and the second rotating wheel 21 can rotate synchronously, thereby achieving the effect of cost saving. The power device 8 of this embodiment is preferably a driving motor, and the output end of the driving motor is drivingly connected to the transmission device 6, and the transmission of the transmission device 6 is driven by the driving motor, thereby driving the first rotating wheel 20 and the second rotating wheel 21 to rotate synchronously. In addition, in order to make the effect of the first rotating wheel 20 and the second rotating wheel 21 driving the metal tube to be flanged to rotate more stable, the present invention also includes a reduction device 7, which is a reducer. The reducer is used to connect the drive motor and the transmission device 6, that is, the output end of the drive motor and the input end of the reducer are driven and connected through a coupling, and the output end of the reducer is driven and connected to the transmission device 6, thereby achieving a deceleration effect.

[0048] In this embodiment, the transmission device 6 includes an output gear 60, a reversing gear 62, a first gear 61 and a second gear 63. The output gear 60 is connected to the output key of the reducer. The reversing gear 62 is rotatably arranged on the frame 1 and meshed with the output gear 60. The first gear 61 is fixed to one end of the first rotating shaft 201 away from the first rotating wheel 20 and meshed with the reversing gear 62. The second gear 63 is fixed to one end of the second rotating shaft 211 away from the second rotating wheel 21 and meshed with the output gear 60. It can be seen that when the output gear 60 rotates clockwise, the second gear 63 rotates clockwise, the reversing gear 62 rotates counterclockwise, and the first gear 61 also rotates clockwise under the action of the reversing gear 62, in the same direction as the second gear 63, thereby achieving the purpose of the first rotating wheel 20 and the second rotating wheel 21 turning in the same direction.

[0049] In this embodiment, the present invention further includes an auxiliary positioning device 9, which is movably disposed on the frame 1 to assist in positioning the metal cylinder to be flanging in a rotating state. Specifically, the auxiliary positioning device 9 includes a mounting shaft 900 and a third rotating wheel 90, the mounting shaft 900 is movably disposed on the frame 1, and the third rotating wheel 90 is rotatably disposed on the mounting shaft 900, so that the third rotating wheel 90 rolls and fits with the outer wall of the metal cylinder to be flanging under the rotational force of the metal cylinder to be flanging. Further, the auxiliary positioning device 9 also includes a second sliding device, which is disposed on the mounting plate 4 to drive the movement of the third rotating wheel 90. Specifically, the second sliding device includes a second mounting seat 92, a second sliding block 91 and a second driving member 93. The second mounting seat 92 is fixed on the mounting plate 4. The second sliding block 91 is slidably connected to the second mounting seat 92 and can move along the movable direction of the second rotating wheel 21. The mounting shaft 900 is fixed on the second sliding block 91. Of course, in order to avoid the interference of the panel 10 with the mounting shaft 900, a third waist-shaped hole 101 is also provided on the panel 10. The length of the third waist-shaped hole 101 is set according to the actual situation and is not limited here. It can be seen that the position of the third rotating wheel 90 can be adjusted by driving the second sliding block 91 to move along the movable direction of the second rotating wheel 21 through the second driving member 93, so that the rolling surface of the third rotating wheel 90 can roll and fit with the outer wall of the metal tube to be flanging to complete the auxiliary positioning, so that the metal tube to be flanging is driven to rotate more stably under the rotational force of the first rotating wheel 20 and the second rotating wheel 21. Of course, those skilled in the art will understand that, in order for the rolling surface of the third wheel 90 to always be in rolling contact with the outer wall of the rotating metal cylinder, a structure identical to and corresponding to that on the circumferential surface of the second wheel 21 is provided on the circumferential surface of the third wheel 90 .

[0050] Of course, in other embodiments, the second driving member 93 may also use other driving structures, such as a cylinder or an electric push rod, etc. Therefore, for those skilled in the art, by reasonably changing the second driving member 93, it should also fall within the protection scope of the present invention.

[0051] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
