Point-focal mechanical three-sheet joint producing process involves using two joint punches on carrier part to stamp local joints

摘要

The joint producing process involves joining three metal sheets (9, 10, 11) held by holding-down devices (5, 6). There are two joint punches (5, 6), one either side of the sheet layers, to form local recesses at the joint points. The two joint punches are on a carrier part (2) along with the adjustable holding-down devices.
