Title: Disc spring manufacturing method
Inventor: SUZUKI TOSHIKAZU
IPC: B23K11/02
Filed: 2017-03-22
Abstract: PROBLEM TO BE SOLVED: To dispose a disc spring manufacturing method which can improve disc spring durability by reducing welding defects remaining at welding points.SOLUTION: A circumferential one end 10A of a strip ring 10 formed in a C shape is butted to the circumferential other end 10B to weld them. For welding, while voltage is being impressed between one end 10A and a contact 10C with the other end 10B to heat the contact 10C, the contact 10C is compressed by pressurization to expand a part of the contact 10C to an outer peripheral side. Next, an expanded part expanded during the welding process is eliminated. This causes most of welding defects occurring upon welding to flow outside with a member constituting the expanded part 10D when the expanded part 10D is produced. Therefore, if the expanded part 10D is eliminated, welding defects remaining at welding points decrease. Consequently, disc durability can improve.SELECTED DRAWING: Figure 4
