Production method of sheet metal blanks for hinges for furniture - stamps double blanks from metal strip and forms recesses in opposite corners

摘要

The metal blanks are stamped out of a strip of metal in such a way that no scrap is produced. A double blank (12a,12b) is first stamped from the metal strip with the straight edges (11) being the original edges of the metal strip. Recesses are formed in two diagonally opposite corners with each recess having one straight edge and one curved. The double blank is then cut into two blanks by cutting along the curved line (13). USE/ADVANTAGE - Manufacture of hinges, mainly, but not exclusively, for furniture. No scrap metal is produced by using this method.
