The whole working process of the automatic flanging machine of the utility model is described below with the accompanying drawings:

referring to fig. 3, a coiled pipe to be processed is fed from the right end of the feed pipe 111, and when the pipe to be processed extends from one end to between the adaptive roller 113 and the driven roller 1101, because the self-adaptive roller 113 is driven by the transmission motor 115 to rotate clockwise, the pipe fitting to be processed is driven to move leftwards and penetrate into the connecting pipe 112 by the rolling friction force of the roller, while since the transfer motor 115 and the swing plate 114 can swing about the spindle 1102 on the mounting plate 110 (refer to fig. 7), under the elastic force of the elastic member 116, the distance between the adaptive roller 113 and the driven roller 1101 can be automatically compensated, so that the adaptive roller 113 does not give excessive pressure to the pipe to be processed, therefore, the pipe fitting to be processed is prevented from being seriously extruded and deformed to influence the subsequent flanging of the pipe fitting, and the transmission mechanism 11 can realize good transmission effect on the pipe fittings with different thicknesses.

Under the guiding action of the connecting pipe 112 in the transfer mechanism 11, the pipe to be processed is finally conveyed to the first clamping block 1201 in the cutting mechanism 12, after the tail end of the pipe extends to the left end of the first clamping block 1201 for a certain distance (the part of the pipe extending to the outer side of the left end of the first clamping block 1201 is used for subsequent flanging treatment), the transfer motor 115 is paused, the vertical feed motor 124 is started to drive the vertical lead screw 124 to rotate, the vertical lead screw 124 drives the first lead screw nut 1211 to convert the rotary motion into the linear motion through thread fit, so that the pressing table 121 is driven to move downwards, and finally the second clamping block 1210 is driven to move downwards to abut against the first clamping block 1201, so that the pipe to be processed is clamped and fixed.

In the flanging assembly 22 of the flanging mechanism 2, the flanging motor 226 drives the driven gear 225 to rotate by meshing with the driving gear 2261, the driven gear 225 rotates to drive the second gear 22022 and the second forming roller 2202 connected with the driven gear to rotate, the second gear 22022 drives the first gear 22012 and the third gear 22032 which are meshed with each other at two sides to rotate by meshing, thereby driving the fourth gear 22042 to rotate simultaneously, thereby driving the first forming roller 2201, the second forming roller 2202, the forming roller 2203 and the ring cutting roller 2204 to rotate simultaneously through gear engagement by the flanging motor 226, and the longitudinal feed motor 222 drives the longitudinal lead screw 223 to rotate through belt transmission, the longitudinal feed table 221 is driven to precisely move along the longitudinal guide rail 102 through the screw fit between the longitudinal lead screw 223 and the second lead screw nut 2213, so that the first forming roll 2201 is first moved into alignment with the pipe to be processed, which is fixed between the first block 1201 and the second block 1210.

Then the transverse feeding motor 227 is started to drive the transverse feeding table 213 to move along the transverse guide rail 2211 to approach the pipe to be processed, during the movement of the first forming roller 2201 along with the transverse feeding table 213, the guide cylinder 2205 at the end of the first forming roller 2201 is firstly inserted into the inner hole of the pipe to be processed for guiding the first cone 22011 to enter the inner hole of the pipe to be processed, as the first forming roller 2201 continues to feed (the inclined surface of the first cone 22011 with the cone angle of 60 degrees is relatively gentle, so that the first cone 22011 can easily enter the initially straight inner hole of the pipe), the first cone 22011 is driven to rotate and enter the inner hole of the pipe, and because the first cone 22011 is of an incomplete cone structure, the side surface of the first cone 22011 is provided with an edge angle, the contact area between the cone surface of the first cone 22011 and the inner wall of the pipe is reduced, and the friction between the first cone 22011 and the inner wall of the pipe is, the pipe fitting is prevented from twisting and deforming during rotation, meanwhile, the edge and corner edges of the rotating first cone 22011 can play a role of reaming the inner pipe wall of the pipe fitting to be machined (the rotating first cone 22011 can rub with the pipe fitting to heat the pipe fitting, so that the deformation of the pipe fitting is facilitated), and the pipe opening of the pipe fitting to be machined is deformed into a 60-degree conical flanging under the dual acting force of extrusion and reaming applied to the pipe fitting by the first cone 22011.
