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.
After the preliminary 60-degree flanging is completed, the transverse feeding motor 227 drives the first cone 22011 to retreat, then the longitudinal feeding motor 222 drives the second forming roller 2202 to move to a position aligned with the pipe fitting, the transverse feeding motor 227 drives the second forming roller 2202 to move towards the pipe fitting, the second cone 22021 at the end part of the second forming roller 2202 firstly plays a role in guiding the second cone 22021 through a guide cylinder 2205 inserted into an inner hole of the pipe fitting, finally the second cone 22021 enters a 60-degree conical flanging inner cavity formed by the preliminary flanging of the pipe fitting, the same second 220cone 21 and the first 22011 exert double acting force on the pipe fitting to extrude the 60-degree conical flanging of the pipe fitting into a 120-degree flanging with the same profile as the second cone 22021, and the rotary extrusion is carried out for a plurality of times to prevent the pipe fitting from generating stress concentration and further cracking, the flanging effect is good.
Then, the sizing roller 2203 is aligned to the pipe to be processed under the driving of the transverse feeding motor 227 and the longitudinal feeding motor 222, the sizing roller 2203 is driven by the transverse feeding motor 227 to move towards the pipe to be processed, the wire cylinder 2205 at the center of the end part of the sizing roller 2203 is inserted into the inner hole of the pipe to be processed, the 120-degree flanging in front of the pipe is extruded through the extrusion plane 22031, and the flanging part of the pipe is pressed against the left end surfaces of the first clamping block 1210 and the second clamping block 1210 through the extrusion plane 22031, so that the pipe orifice of the pipe forms a final flanging structure vertical to the side wall of the pipe; finally, the transverse feeding motor 227 and the longitudinal feeding motor 222 drive the shaping roller 2203 to withdraw, the circular cutting roller 2204 is aligned with the flanged pipe fitting, the circular cutting roller 2204 cuts the outer edge of the flanged part of the pipe fitting through the circular cutting knife 22041 with the end rotating, and burrs and uneven edges of the flanged outer edge are cut and removed.
After the flanging process is completed, the vertical feeding motor 124 in the cutting mechanism 12 drives the second clamping block 1210 to move upwards to separate from the first clamping block 1201, then the transmission motor 115 drives the pipe to be processed to be sent out by a required length, the vertical feeding motor 124 drives the second clamping block 1210 to move downwards again to fix the pipe, then the cutting motor 122 is started to drive the roller 1222 to rotate eccentrically through the driving shaft 1221, so that the roller 1222 rotates to the uppermost position, the cutting blade 123 is driven to slide upwards to cut the flanged pipe from the coiled pipe, then the vertical feeding motor 124 drives the second clamping block 1210 to move upwards to separate from the first clamping block 1201, the pipe is driven by the self-adaptive roller 113 to move leftwards to leak a small length, and the pipe is subjected to subsequent flanging treatment.
When pipe fittings with different specifications need to be flanged and the flanging roller set 220 needs to be replaced, only the base 210 bearing the flanging roller set 220 in the bearing assembly 21 needs to be replaced quickly, firstly the fastening screw 212 is detached, the base 210 is lifted up around the oblique wedge head 2102 to detach the base 210, then the oblique wedge head 2102 of the base 210 provided with different flanging roller sets 220 is inserted into the oblique wedge groove 21311 on the transverse feeding table 213, then the base 210 is put down to enable the positioning groove 2105 at the bottom of the base 210 to be aligned and inserted into the positioning protrusion 2132 of the transverse feeding table 213, the driven gear 225 is shifted to be meshed with the driving gear 2261, finally the fastening screw 212 is screwed into the threaded through hole 2103 again, the end part of the fastening screw 212 is tightly pressed on the conical surface 2112 on the limiting body 211, and the base 210 is enabled to be continuously and tightly adhered to the upper table surface of the transverse feeding table 213, finally, the base 210 is accurately positioned and fastened, and the flanging roller group 220 in the bearing component 21 is quickly replaced.
