Draw press with a fixed draw punch and a floating draw punch

摘要

A machine is disclosed for producing a deep drawn part and a shallow drawn part from sheet metal blanks in a single action draw press. A floating draw punch and a fixed draw punch are provided. The first draw die forms a part that is drawn over the fixed draw punch while the second blank does not begin forming the second part until the floating draw punch bottoms out on the bed of the press. The floating draw punch moves with the binder ring until the additional draw depth required to form the deep drawn part is essentially equal to the draw depth of a shallow drawn part. A process for producing multiple unattached sheet metal parts in a single action draw press is also disclosed wherein a first sheet metal part has a draw depth D₁ and a second sheet metal part has a draw depth D₂.
