Abstract
The present invention relates to a spinning apparatus for forming a workpiece when the workpiece is arranged in a substantially vertical orientation. The spinning apparatus includes at least one tool capable of altering the shape of the workpiece while spinning. The apparatus also includes a clamp configured to hold the workpiece as the tool works the workpiece. The spinning apparatus includes a spinning arrangement allowing for the vertical arrangement of the workpiece while the tool is working on the workpiece.
Claims33
A spinning apparatus comprising:
- a clamp including a receiving area adjustable in size and configured to receive at least a portion of a workpiece along a vertical axis;
- a spinning arrangement having at least one roller assembly capable of acting on the workpiece along an axis transverse to said vertical axis in order to form at least a portion of the workpiece the spinning arrangement further comprising a spinner head comprising a housing, a hub and at least one roller assembly;
- the roller assembly include a link arm, a connector arm, a pivot and a roller, wherein the link arm is configured to rotate about the pivot and the roller is connected to the link arm at one end and the connector is connected to the link arm at an end of the link arm opposite the roller;
- a frame configured to support the clamp and the spinning arrangement;
- wherein one of the clamp or the spinning arrangement is located vertically above the other of the clamp or the spinning arrangement;
- and
- a drive mechanism to drive the spinning arrangement in a rotational sense along the vertical axis about the workpiece.

A device for shaping at least an end of a workpiece comprising:
- a clamp for holding the workpiece;
- a spinning assembly including at least one working member capable of forming at least a portion of the workpiece;
- and
- a frame configured to support the clamp and the arrangement above a floor;
- wherein the clamp and the spinning assembly may be positioned substantially along an axis extending in a direction substantially perpendicular to the floor, and the spinning assembly has at least one roller assembly capable of acting on the workpiece along an axis transverse to said axis, and
- wherein at least one of the assembly and the clamp is moveable relative to the other along first and second axes where the second axis is substantially perpendicular to the first axis, and the clamp is capable of pivoting with respect to the spinning assembly.

A spinning apparatus comprising:
- a clamp including a receiving area adjustable in size and configured to receive at least a portion of a workpiece along a vertical axis;
- a spinning arrangement having at least one roller assembly capable of acting on the workpiece along an axis transverse to said vertical axis in order to form at least a portion of the workpiece, a longitudinal axis extends substantially through the center of the spinning arrangement, and the clamp is configured to tilt the workpiece with respect to the longitudinal axis;
- a frame configured to support the clamp and the spinning arrangement;
- wherein one of the clamp or the spinning arrangement is located vertically above the other of the clamp or the spinning arrangement, and at least one of the clamp and the spinning arrangement is moveable with respect to the other of the clamp and the spinning arrangement in a substantially vertical and horizontal direction;
- and
- a drive mechanism to drive the spinning arrangement in a rotational sense along the vertical axis about the workpiece.
3 more elements
A device for shaping at least an end of a workpiece comprising:
- a clamp for holding the workpiece, the clamp includes a receiving area defined by at least two clamping members, at least one plate partially in contact with one of the clamping members, a motor, a chain, at least one worm, and at least one worm gear including at least one threaded rod, wherein the motor is connected to the at least one worm by way of the chain, the at least one worm engages the at least one worm gear and the threaded rod is interconnected to the at least one plate so that rotation of the threaded rod causes movement of the at least one plate and the movement of the at least one plate causes movement of at least one of the clamping members to alter the size of the receiving area;
- a spinning assembly including at least one working member capable of forming at least a portion of the workpiece;
- and
- a frame configured to support the clamp and the arrangement above a floor;
- wherein the clamp and the spinning assembly may be positioned substantially along an axis extending in a direction substantially perpendicular to the floor, and the spinning assembly has at least one roller assembly capable of acting on the workpiece along an axis transverse to said axis.

A device for shaping at least an end of a workpiece comprising:
- a clamp for holding the workpiece;
- a spinning assembly including at least one working member capable of forming at least a portion of the workpiece;
- and
- a frame configured to support the clamp and the arrangement above a floor, the frame comprising:
- a first frame portion and a second frame portion and the first frame portion and the second frame portion each include a base member extending substantially horizontally,
- an upright member connected to the base extending substantially vertically and a support member extending between the base member and the upright member;
- wherein
- the clamp and the spinning assembly may be positioned substantially along an axis extending in a direction substantially perpendicular to the floor, and the spinning assembly has at least one roller assembly capable of acting on the workpiece along an axis transverse to said axis.
