The implementation mode is as follows:

referring to fig. 1-8, the invention shows a flanging machine for stainless steel chimney processing, comprising a frame 1, a rotating device 2 and a flanging device 3, wherein the rotating device 2 is rotatably arranged on the frame 1 and is used for driving a metal cylinder to be flanged to rotate; the flanging device 3 comprises a flanging wheel 30 and a driving device 31, the flanging wheel 30 is movably arranged on the rack 1 and can be used for treating the radial direction movement of the flanging metal cylinder, the driving device 31 is used for driving the flanging wheel 30 to move, so that the flanging wheel 30 can move outwards along the radial direction of the to-be-flanged metal cylinder of the rotating device 2 and from the to-be-flanged metal cylinder for flanging, or can move inwards along the radial direction of the to-be-flanged metal cylinder of the rotating device 2 and from the to-be-flanged metal cylinder for flanging. When the flanging machine is used, a metal cylinder to be flanged is rotated through the rotating device 2, and based on the fact that the metal cylinder to be flanged (a stainless steel chimney section) is in a rotating state, the flanging wheel 30 is driven by the driving device 31 to move outwards along the radial direction of the metal cylinder to be flanged and from the inside of the metal cylinder to be flanged for flanging, or move inwards along the radial direction of the metal cylinder to be flanged and from the outside of the metal cylinder to be flanged for flanging, so that the automatic flanging effect is achieved.

As can be understood by those skilled in the art, when the present invention is applied to flanging, the original position of the flanging wheel 30 is located in the metal cylinder to be flanged, and the flanging wheel 30 is located at a preset position of the port of the metal cylinder to be flanged, and is driven by the driving device 31 to move from inside to outside along the radial direction of the metal cylinder, so as to realize flanging of the metal cylinder; when the flanging device is applied to the inward flanging, the original position of the flanging wheel 30 is positioned outside the metal cylinder to be flanged, the flanging wheel 30 is positioned at the preset position of the port of the metal cylinder to be flanged, and the flanging wheel is driven by the driving device 31 to move from outside to inside along the radial direction of the metal cylinder, so that the inward flanging of the metal cylinder is realized.

In this embodiment, a panel 10 is fixedly disposed at the top end of the rack 1, and a first waist-shaped hole 100 is disposed on the panel 10, and the first waist-shaped hole 100 penetrates through the upper and lower portions of the panel 10. The rotating device 2 comprises a first rotating wheel 20 and a second rotating wheel 21 which are oppositely arranged on the rack 1 and can synchronously rotate, the first rotating wheel 20 is rotatably arranged on the rack 1 through a first rotating shaft 201 and a first bearing with seat 203, the second rotating wheel 21 is rotatably arranged on the rack 1 through a second rotating shaft 211 and a second bearing with seat 213, one end of the first rotating shaft 201 penetrates through the first waist-shaped hole 100, one end of the second rotating shaft also penetrates through the first waist-shaped hole 100, a center hole of the first rotating wheel 20 is in key connection with one end of the first rotating shaft 201 penetrating through the first waist-shaped hole 100, and a center hole of the second rotating wheel 21 is in key connection with one end of the second rotating shaft penetrating through the first waist-shaped hole 100. Certainly, the bottoms of the first rotating wheel 20 and the second rotating wheel 21 do not collide with the panel 10, and in addition, a gap for driving the metal cylinder to be flanged to rotate exists between the first rotating wheel 20 and the second rotating wheel 21, so it can be known that the rotating directions of the first rotating wheel 20 and the second rotating wheel 21 are the same, so when the thick wall of the metal cylinder to be flanged is tightly attached by the first rotating wheel 20 and the second rotating wheel 21, that is, the outer wall of the metal cylinder to be flanged is tightly attached by the circumferential surface of the first rotating wheel 20, and the inner wall of the metal cylinder to be flanged is tightly attached by the circumferential surface of the second rotating wheel 21, so that the metal cylinder to be flanged can be driven to rotate under the rotating action force of the first rotating wheel 20 and the second rotating wheel 21, and further, the effect of rotating the metal cylinder to be flanged is achieved. Of course, it will be understood by those skilled in the art that the metal cylinder to be flanged does not interfere with the panel 10 during rotation.

In this embodiment, the circumferential surface of the first rotor 20 is provided with a first protruding portion 200 along the circumferential direction thereof, and the second rotor 21 is provided with a first recessed portion 210 adapted to the first protruding portion 200, that is, the circumferential surface of the second rotor 21 is also provided with a first recessed portion 210 along the circumferential direction thereof, and the first recessed portion 210 corresponds to the position of the first protruding portion 200 and can be matched with the first protruding portion 200. On the basis, the second runner 21 is movably disposed on the frame 1 and can move toward the direction close to the first runner 20, so that the caliber of the to-be-flanged port of the rotating metal cylinder can be expanded to form a bell mouth under the action of the first concave portion 210 and the first convex portion 200. Because first bulge 200 is located the outer wall of treating the turn-ups metal cylinder and is close to the position of treating the turn-ups port of treating the turn-ups metal cylinder, first recess 210 is located the inner wall of treating the turn-ups metal cylinder and is close to the position of treating the turn-ups port of treating the turn-ups metal cylinder and corresponds with first bulge 200, consequently, treat that the turn-ups metal cylinder carries out the pivoted state under the rotational action of first runner 20 and second runner 21, when moving second runner 21 to the direction that is close to first runner 20, treat that the turn-ups metal cylinder can expand the bore of treating the turn-ups port of treating the turn-ups metal cylinder under the mating reaction of first bulge 200 and first recess 210, thereby can expand and be formed with the horn mouth.

It is worth to say that, when the bore of the port to be flanged of the metal cylinder forms a bell mouth, the flanging wheel 30 which is located in the metal cylinder and close to the port to be flanged is driven by the driving device 31 to move outwards along the radial direction of the metal cylinder to be flanged and from the inside of the metal cylinder to be flanged for flanging, so that the expanded metal wall can be flanged quickly, the effect of realizing quick flanging is achieved, and the flanging effect is better.

That is, it can be understood that the circumferential surface of the second runner 21 is also provided with a second recessed portion 212, and the second recessed portion 212 is also provided in the circumferential direction of the second runner 21 and can be correspondingly matched with the second protruding portion 202 of the first runner 20, the second protruding portion 202 is an annular protruding member, and the second recessed portion 212 is an annular groove. Therefore, when the second rotating wheel 21 is moved towards the direction close to the first rotating wheel 20 in the state that the metal cylinder to be flanged rotates under the rotating acting force of the first rotating wheel 20 and the second rotating wheel 21, the metal cylinder to be flanged can be formed with reinforcing ribs on the rotating metal cylinder under the matching action of the annular protruding part and the annular groove, and the effect of reinforcing the rigidity of the metal cylinder (stainless steel chimney section) is achieved.

Specifically, the auxiliary positioning device 9 includes an installation shaft 900 and a third rotating wheel 90, the installation shaft 900 is movably disposed on the frame 1, and the third rotating wheel 90 is rotatably disposed on the installation shaft 900, so that the third rotating wheel 90 is in rolling fit with the outer wall of the metal tube to be flanged under the rotating action force of the metal tube to be flanged. Further, the auxiliary positioning device 9 further includes a second sliding device, and the second sliding device is disposed on the mounting plate 4 and is used for driving the third rotating wheel 90 to move. Specifically, the second sliding device includes a second mounting seat 92, a second sliding block 91 and a second driving element 93, the second mounting seat 92 is fixed on the mounting plate 4, the second sliding block 91 is slidably connected with the second mounting seat 92 and can move along the direction in which the second runner 21 moves, and the mounting shaft 900 is fixed on the second sliding block 91, of course, in order to avoid the interference of the panel 10 on the mounting shaft 900, a third kidney-shaped hole 101 is further provided on the panel 10, and the length of the third kidney-shaped hole 101 is set according to the actual situation, and is not limited herein. Therefore, 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 part 93, so that the rolling surface of the third rotating wheel 90 can be in rolling fit with the outer wall of the metal tube to be flanged, the auxiliary positioning is completed, and the metal tube to be flanged is driven to rotate more stably under the rotating action force of the first rotating wheel 20 and the second rotating wheel 21. Of course, it will be understood by those skilled in the art that the third runner 90 has the same and corresponding configuration as the second runner 21 on the circumferential surface thereof so that the rolling surface of the third runner 90 can always roll against the outer wall of the rotating metal cylinder.

Of course, in other embodiments, the second driving member 93 may also be driven by other driving structures, such as an air cylinder or an electric push rod, and therefore, it should be within the scope of the present invention for those skilled in the art to reasonably modify the second driving member 93.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
