ABSTRACT:
A method and apparatus for forming sheet metal parts of complex configuration and/or sheet metal parts including inherent joints. The part is formed in a continuous run through a stamping press wherein a strip of sheet metal is moved incrementally and continuously through a plurality of successive stations where a plurality of hits are made on the sheet to successively cut and form the sheet to gradually form the individual stamped parts. A special compound die is disclosed for forming a complete loop in each part during the run through the stamping press and for forming a doubled over portion of the part including upper and lower layers, and a clinching station is provided as a station within the stamping press for mechanically joining the doubled over layers of the part together to form a successive plurality of separate parts each having a doubled over portion clinched together.
