s2, molding: after the step S1 is completed, a first motor (31) is started at the moment, the first motor (31) drives a driving gear (32) to rotate, the driving gear (32) drives a driven gear (34) to rotate, the driven gear (34) drives a rotating rod (33) to rotate, the rotating rod (33) drives a clamping frame (35) to rotate, and therefore the central air-conditioning copper pipe clamped and fixed is driven to rotate, the motor is started at the same time, a driving motor (26) drives a screw rod (24) to rotate, at the moment, under the action of a guide rod (25), a circular fixing plate (23) moves downwards, and therefore the central air-conditioning copper pipe clamped and fixed is driven to move downwards and rotates out of a second circular through hole (232) in a circular die head (231), and at the moment, the central air-conditioning copper pipe is processed;

s3, blanking: after S2 step is completed, when the central air-conditioning copper pipe which needs to be molded is rotated out of a circular through hole (232) in a circular die head (231), the molded central air-conditioning copper pipe is made to fall into an annular circular block (352) arranged on the inner annular surface of a circular hollow cylinder (43), after the central air-conditioning copper pipe is molded, an electric push rod (453) is started at the moment, the electric push rod (453) pushes a rack (454) to move, the rack (454) drives a gear (451) to move, the gear (451) drives a rotating shaft (41) to rotate, so that a transmission belt (42) is driven to move, the molded central air-conditioning copper pipe is made to move to the right side, and blanking is facilitated.
