摘要

PROBLEM TO BE SOLVED: To provide a device and a method for pressing a weld zone of a drum can by which the weld zone of the drum of the drum can is exactly pressed and is uniform in shape and mechanical properties over the whole length thereof, and a drum can manufacturing device. SOLUTION: In the drum can weld zone pressing device 120 to squeeze a weld zone 201 of a drum part 200 of the drum can formed by rolling a steel sheet, a support arm 121 having a positional deviation preventive part 1211 is provided to hold the drum part by the support arm without any positional deviation when pressing the weld zone. Thus, the weld zone can be pressed correctly. The weld zone can be uniform in shape and mechanical properties over the whole length by changing the pressing method at an end portion and a center portion of the weld zone.
