WINDOW SPACER FRAME PUNCH ASSEMBLY

摘要

An apparatus and method is provided for forming a spacer frame assembly used in the construction of insulating glass unit windows. The apparatus comprises a head arrangement having a body with first and second ends, the first end for coupling to a cylinder that advances and retracts the head arrangement in a reciprocating motion during operation. The second end includes an annular wedge-shaped ridge for coupling to a second annular wedge-shaped ridge of a die support, collectively the wedge-shaped ridge and second wedge-shaped ridge form a contact region to form a torus surface. The die support has at least one die for engaging a spacer frame assembly during operation. The apparatus further comprises a collar having a torus-shaped recess corresponding with the torus surface to nest and couple the body to the die support.
