AI Technical Summary

Benefits of technology

[0012]The thickness of the take-off tongues measured normal to the respective inner surface is expediently constant. The inner surfaces are in particular planar and without radial projections or recesses so that the can body to be taken off can be easily moved along the inner surfaces.

Problems solved by technology

The manufacture of such a take-off ring is expensive: The take-off elements need to be set correctly aligned to a common radius.

Embodiment Construction

[0019]FIGS. 4 and 5 show a preferred exemplary embodiment of a take-off ring 10. The take-off ring 10 is preferably installed in an apparatus for the manufacture of can bodies 11. Such an apparatus can also be called a deep-draw press 12 and is shown schematically in FIG. 1. The deep draw press 12 includes a down holder 13 with a hollow cylindrical down holder section 14. The down holder 13 can be moved by a down holder drive 15 in an operating direction Z. The operating direction Z extends parallel to the longitudinal axis of the down holder 13.

[0020]Co-axially with regard to the down holder 13 a drawing plunger 18 is arranged. The drawing plunger 18 can be moved in this movement through the hollow-cylindrical down holder section 14 by a plunger drive 19 into a draw-down or deep-draw opening 20 of a lower tool 21 provided herefor. The draw-down opening 20 in the lower tool 21 is hollow cylindrical and may have several concentric sections with different radii. The draw-down opening ...

Abstract

The invention relates to a take-off ring 10 which is provided in particular for use in connection with deep-draw presses 12. It serves for removing a top-shaped can body 11 from a drawing plunger 18. The take-off ring 10 includes a multitude of take-off elements 27 which are arranged uniformly distributed in circumferential direction U and separated in each case by a gap 48. The take-off elements 27 are interconnected by an annular base section 30 which extends around the take-off elements 27 in the circumferential direction U. Radially inwardly a spring section 38 and a transition section 39 of the take-off element follow. The transition section 39 is pivotable by way of the spring section 38 about a pivot axis 55 which extends in the circumferential direction U. A take-off tongue 35 extends in a transverse direction away from the transition section 39 toward a free end 41.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority of German Application No. 10 2010 019 322.4-14 filed May 3, 2010.BACKGROUND OF THE INVENTION[0002]The invention resides in a take-off ring which is suitable especially for use in an apparatus for the manufacture of can bodies, for example, in deep-draw presses. In such, apparatus can bodies for pressure containers or beverage cans are manufactured. The can body includes a can bottom and, extending therefrom a can wall which is manufactured from a blank of a single material without a seam or joint area. During this manufacturing process, the can body is disposed on a draw plunger. After the can bottom and the can wall have the desired shape, the can body must be removed from the draw plunger. This is the purpose of the take-off ring.[0003]Such a take-off ring is known, for example, from DE 23 35 686. The take-off ring includes several take-off elements which are held together by an elastic means. This el...
