Abstract
A tip assembly includes a tip having a nose portion. The tip defines a central bore. The nose portion includes a lip portion and defines a counterbore. The counterbore has a counterbore side wall and a seat surface. The counterbore is contiguous with the central bore. An insert member includes an inner surface, an outer surface and a side wall. The inner surface is opposite the outer surface. The side wall interconnects the inner surface and the outer surface. The insert defines a central aperture that extends from the inner surface to the outer surface. The insert is disposed within the counterbore such that the central aperture is substantially concentric with the central bore of the tip. The lip portion of the tip engages the outer surface of the insert.
Claims16
A die assembly, comprising:
- a die holder;
- a die member;
- and
- a tip assembly, comprising:
- a tip having a nose portion, said tip defining a central bore, said nose portion including a lip portion and defining a counterbore, said counterbore having a counterbore side wall and a seat surface, said counterbore being contiguous with said central bore;
- and
- an insert member having an inner surface, an outer surface and a side wall, said inner surface being opposite said outer surface, said side wall interconnecting said inner surface and said outer surface, said insert defining a central aperture extending from said inner surface to said outer surface, said insert disposed within said counterbore such that said central aperture is substantially concentric with said central bore of said tip, said lip portion of said tip engaging said outer surface of said insert.
A tip assembly, comprising:
- a tip having a nose portion, said tip defining a central bore, said nose portion including a lip portion and defining a counterbore, said counterbore having a counterbore side wall and a seat surface, said counterbore being contiguous with said central bore;
- and
- an insert member having an inner surface, an outer surface and a side wall, said inner surface being opposite said outer surface, said side wall interconnecting said inner surface and said outer surface, said insert defining a central aperture extending from said inner surface to said outer surface, said insert disposed within said counterbore such that said central aperture is substantially concentric with said central bore of said tip, said lip portion of said tip engaging said outer surface of said insert.
A method of placing an insert in a tip of a die assembly, said tip defining an axial bore through which a filament is drawn in a direction of travel, said method comprising the steps of:
- disposing an insert in association with said bore such that an aperture defined through the insert is disposed in substantially concentric relation with said bore;
- and
- precluding axial movement of said insert relative to said tip by one of rolling and folding a lip portion of the tip into abutting engagement with an outer surface of said insert.
