Formation and rotational apparatus and method for cylindrical workpieces
A formation and rotation apparatus for use in forming and rotating interconnected sections of a cylindrical workpiece, including a frame and a head arranged within the frame, the head defining two slots and being operatively rotated via an integral drive assembly. A first slide block is slidably disposed within one of the two slots, and a second slide block is disposed within another of the two slots, each of the first and the second slide blocks include a cutting wheel and a beading wheel for successively forming each of the interconnected sections. An armature having an axis of rotation is also provided, along with a gripping mechanism being operatively connected to the armature. A drive mechanism selectively rotates the armature about the axis of rotation after the gripping means has closed about one of the interconnected sections.
1. A method for automatically rotating interconnected sections of a cylindrical workpiece, said method comprising the steps of:
securing said workpiece about a rotational axis;
forming a gripping means to include a pair of gripping fingers, said gripping means being capable of rotation parallel to said rotational axis;
operatively disposing a revolving cutting head mechanism adjacent to said gripping means, said revolving cutting head mechanism including a head configured for rotation, said head defining two slots therein, a first slide block slidably disposed within one of said two slots, and a second slide block disposed within another of said two slots, each of said first and said second slide blocks include a cutting wheel and a beading wheel;
forming said interconnected sections using two said cutting wheels of said revolving cutting head mechanism;
selectively closing said gripping fingers about at least one of said interconnected sections; and
rotating said gripping means such that said at least one of said interconnected sections is rotated by a predetermined amount about said rotational axis.
2. The method for automatically rotating interconnected sections of a cylindrical workpiece according to claim 1 , said method further comprising the steps of:
disposing an adjustable stop means to arrest said rotation of said gripping means; and
rotating said gripping means between 0 and 360 degrees.
