Apparatus for pointing work pieces
First Claim
1. A tube shaping machine comprising a plurality of dies each having a substantially continuous, unbroken working surface, a substantially straight support leg for supporting said working surface and for defining lateral side portions thereof and forming a predetermined angle with respect to said working surface, and a substantially straight actuating leg for driving said support leg and formed continuously therewith and at a second predetermined angle with respect thereto, means for mounting said dies and for aligning said working surfaces one adjacent to the next so as to form a tube-receiving aperture therethrough, which aperture defines in cross-section a regular polygon, and means for simultaneously reciprocating each of said plurality of dies along a predetermined straight line throughout a range of positions between a fully open position and a fully closed position of said tube shaping machine while maintaining a similar regular polygonal cross-sectional shape of said tube-receiving through aperture throughout said range of positions.

Abstract
A tube shaping machine includes a plurality of dies each having a substantially continuous, unbroken working surface. These dies are mounted with the working surfaces positioned one adjacent to the next so as to form a tube-receiving aperture therethrough, which aperture defines in cross-section regular polygon. The dies are substantially identical in configuration, this configuration being such that reciprocating each of the dies along a predetermined straight line throughout a range of positions between a fully open position and a fully closed position of the tube-receiving aperture maintains a similar regular polygonal cross-sectional shape of said tube-receiving through aperture throughout said range of positions.

- 1. A tube shaping machine comprising a plurality of dies each having a substantially continuous, unbroken working surface, a substantially straight support leg for supporting said working surface and for defining lateral side portions thereof and forming a predetermined angle with respect to said working surface, and a substantially straight actuating leg for driving said support leg and formed continuously therewith and at a second predetermined angle with respect thereto, means for mounting said dies and for aligning said working surfaces one adjacent to the next so as to form a tube-receiving aperture therethrough, which aperture defines in cross-section a regular polygon, and means for simultaneously reciprocating each of said plurality of dies along a predetermined straight line throughout a range of positions between a fully open position and a fully closed position of said tube shaping machine while maintaining a similar regular polygonal cross-sectional shape of said tube-receiving through aperture throughout said range of positions.
- 3. A tube shaping machine comprising a plurality of dies each having a substantially continuous, unbroken working surface, a substantially straight support leg for supporting said working surface and for defining lateral side portions thereof and forming a predetermined angle with respect to said working surface, and a substantially straight actuating leg for driving said support leg and formed continuously therewith and at a second predetermined angle with repect thereto, means for relatively mounting said dies so that the working surfaces thereof collectively define a tube-receiving aperture having a substantially continuous and unbroken composite working surface both peripherally and longitudinally, and means for simultaneously reciprocating each of said plurality of dies along a predetermined straight line throughout a range of positions between a fully open position and a fully closed position of said tube shaping machine, while maintaining a tube to be shaped therein substantially fully peripherally and longitudinally supported throughout said range of positions.

8. A die for use with a tube forming machine, said die including a substantially flat, continuous and unbroken working surface capable of alignment with flat working surfaces of other like dies for collectively defining substantially the sides of a regular polygon, a substantially straight support leg for supporting said working surface, and for defining a pair of parallel, spaced apart lateral side portions of said working surface at a first predetermined angle with respect thereto, and a substantially straight actuating leg for driving said support leg and formed continuously therewith and at a second predetermined angle with respect thereto, said first predetermined angle being such that said working surface and one of the lateral side portions thereof define, respectively, one side of said regular polygon and an extension of a side of said regular polygon next adjacent to said one side of said regular polygon and said second predetermined angle being chosen so that movement of the die along the longitudinal axis of the actuating leg will maintain a similar regular polygon when said plurality of like dies are initially to aligned and thereafter simultaneously moved a like amount along their respective actuating leg longitudinal axes.
