Abstract

An insertion die for the installation of an internally-threaded flange into a drum head by means of a single stroke cycle of a cooperating press includes components arranged for piercing a hole in the drum head and crimping a raised embossment which is formed in the drum head over and around the flange for securely anchoring the flange into the drum head embossment. The insertion die is configured with two workstations, one for a two inch inside diameter flange and the other for a 3/4 inch inside diameter vent closure. The insertion die includes a moveable die center at each workstation which is initially positioned in a blocking configuration to prevent crimping jaws from closing. The die center is moveable to a lower position below the crimping jaws which allows the jaws to act on the drum head embossment for crimping the embossment onto the flange. The die center is moveable from a blocking position to a release position based upon the state of a release mechanism which includes a three pin configuration and the shifting of the middle pin which allows the die center to drop down below the crimping jaws.
