Abstract:
An arrangement for working a tube end includes: an operating cylinder with a piston displaceable along an longitudinal axis; and a tube mounting, a tool holder being provided at an end of the piston facing the tube mounting. The operating cylinder is provided as a tandem cylinder. At least two cylinder stages are offset along the longitudinal axis. The piston includes connected piston segments, each piston segment being allocated to a cylinder stage.
Abstract:
A shaping tool as depicted in exemplary FIG. 3 comprising a rotatable base member having at least one profiled bending roller (13) which is mounted on a circular track and is rotatable about a rotation axis. The bending roller (13) arranged on a radially movable slide (11) is movable from a position defining a maximum working aperture for the tool, by means of a spring-loaded lever (9) which has an axial configuration, into a position defining a minimum working aperture for the tool.
Abstract:
An apparatus or tool for simultaneously cutting an end and forming a groove in a tube includes at least one cutter for cutting the tube and at least one roller for forming a groove in the tube. The cutter can include a profile for simultaneously cutting the tube and forming a shaped end of the tube. In one aspect, a body and a carrier are used to make the at least one cutter and the at least one roller relative to the tube. In another aspect, a pair of opposing dies are used to move the at least one cutter and the at least one roller with respect to the tube. The dies can be moved by a drive shaft connected to an output of an electric power drill.
Abstract:
A knurling tool having three knurling wheels adapted to be positioned about a workpiece to be knurled and in which one of these knurling wheels is mounted on a movable block which is adjustably positionable against the workpiece. A quick release mechanism is included which will release the workpiece without affecting the relative working position of the knurling rollers.
Abstract:
A method of forming a smooth shoulder (16, 14b, 19b), neck (17, 37) and flange (18, 38) at the open end of the cylindrical side wall (12) of a can body (10) comprises the steps of forcing a marginal edge portion (13) of the side wall into at least a first die to form a first portion of reduced diameter having a first shoulder portion (14) and a first cylindrical portion (15); and optionally applying at least one rolling operation to the first portion of reduced diameter, and any further die formed portions of reduced diameter subsequently formed, to generate a smooth shoulder (16, 14, 19b), neck (17, 37) and flange (18, 38). Reference is made to the roll forming process described and claimed in British Pat. No. 1,534,716 as being particularly suitable. The margin-portion (13) is preferably thicker than the rest of the side wall (12).
Abstract:
A method of producing a metal can or similar object by drawing and ironing wherein subsequent to the drawing process the edge of the can or object is cut to size, while the can or object is rotated about its longitudinal axis, by means of a laser beam whereby the deformation properties of the edge are improved.
Abstract:
Apparatus for swaging the tips of ballpoint pens comprises three identical working rollers each having a conical running surface and a conical or otherwise rotatively contoured working surface. The conical running surfaces roll on a conical seat whose apex coincides with the axes of the three conical running surfaces of the rollers, thereby to avoid slippage.
Abstract:
A method and apparatus for forming a necked-in and flanged can body wherein an end of the body is forced by a spinning roll into a spinning groove, which is formed jointly by continuous groove segments formed both in a spinning pilot and in a spinning anvil, the spinning roll being movable to a limited degree axially of the body so that relative axial movement between the spinning members is obtained to permit the spinning operation to progress to completion. The axial movement of the movable spinning roll is obtained automatically by spring mounting it on its shaft so that it can slide along the shaft as the contour of the body changes.
