and then the to-be-machined part 23 is sent into a first flattening mechanism 3 in the flattening mechanism 3 through a feeding mechanism to process a port at one end of the to-be-machined part 23, then is sent into a second flattening mechanism 3 to process a port at the other end, after the processing is completed, the to-be-machined part 23 is sent into a corresponding plugging mechanism 2 to plug pipe orifices at two ends of the to-be-machined part through the first plugging mechanism 2 and the second plugging mechanism 2, after all the processing is completed, the to-be-machined part 23 is placed into a discharging bin 1 through the feeding mechanism, and after a certain amount of to-be-machined part is placed into the discharging bin 1, the processed to-be-machined part 23 is recovered by workers.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
