Method of producing bushing and piece with bushing

Abstract

This disclosure relates to bushings produced with adapted dovetails for production on a carrying web of a progressive stamping machine at a plurality of stations. The bushing includes a regular shape male dovetail inserted into an irregular shape crenellated female opening at the conclusion of a plurality of operations at stations on a progressive stamping machine. Once the bushing is bent in shape, in a subsequent step, the regular shape male dovetail is punched to lock in place into the irregular shape crenellated female opening.

What is claimed is: 
     
         1 . A piece with at least a bushing produced in a progressive die stamping technology, the bushing comprising:
 a circular body having a top edge and a bottom edge and a locking interface, wherein the locking interface includes a front end with at least a regular shaped dovetail and a back end with a mating irregular shaped opening, the front end and the back end between the top and bottom ends, wherein the regular shaped dovetail is mated in the irregular shaped opening, and wherein the regular shaped dovetail is punched and deformed to lock in the mating irregular shaped opening.   
     
     
         2 . The piece of  claim 1 , wherein the bushing further comprising embosses on an external surface, and wherein the embosses are U shaped with a flat bottom 
     
     
         3 . The piece of  claim 1 , wherein the regular shaped dovetail of the bushing is of a rectangular shape. 
     
     
         4 . The piece of  claim 3 , wherein the irregular shaped opening is a U shaped opening with a wider bottom portion and where a top portion is of the same size as the regular shaped dovetail.
