Take-off ring

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.

1 . Take-off ring ( 10 ), in particular an arrangement ( 12 ) for the manufacture of a can body ( 11 ), said take-off ring ( 10 ) comprising:
 an annular base section ( 32 ) by which several take-off elements ( 27 ) are interconnected,   each take-off element ( 27 ) includes a spring section ( 38 ) which extends radially inwardly from the base section ( 32 ) and has a pivot axis ( 55 ) which extends in a circumferential direction (U), each take-off element ( 27 ) includes a radially inwardly disposed transition section ( 39 ) from which a take-off tongue ( 35 ) extends transverse to the radial direction and transverse to the circumferential direction (U) and which is supported so as to be pivotable about the pivot axis ( 55 ).   
     
     
         2 . Take-off ring ( 10 ) according to  claim 1 , wherein the base section ( 32 ) and each take-off element ( 27 ) consist of the same material and are manufactured from a single piece without connecting points or joints. 
     
     
         3 . Take-off ring ( 10 ) according to  claim 1 , wherein the take-off tongue ( 35 ) extends over the full axial length of the take-off ring ( 10 ). 
     
     
         4 . Take-off ring ( 10 ) according to  claim 1 , wherein the take-off tongue ( 35 ) extends in its rest position at an inclined angle with respect to a longitudinal axis (L) of the take-off ring ( 10 ). 
     
     
         5 . Take-off ring ( 10 ) according to  claim 1 , wherein the take-off tongue ( 35 ) having a radially inwardly positioned free end ( 41 ), the take-off tongue ( 35 ) at its radially inwardly positioned free end ( 41 ) has a front face ( 45 ) which serves as a support surface ( 45 ), which serves as abutment area ( 46 ) for the can body ( 11 ) to be taken off. 
     
     
         6 . Take-off ring ( 10 ) according to  claim 1 , wherein the take-off tongues ( 35 ) of the take-off elements ( 27 ) each have an inwardly facing planar inner surface area ( 42 ). 
     
     
         7 . Take-off ring ( 10 ) according to  claim 6 , wherein the inner surface areas ( 42 ) of all take-off elements ( 27 ) are disposed on the outer surface of a common truncated cone. 
     
     
         8 . Take-off ring ( 10 ) according to  claim 1 , wherein each two adjacent take-off elements ( 27 ) are separated from each other by a gap ( 48 ). 
     
     
         9 . Take-off ring ( 10 ) according to  claim 8 , wherein each gap ( 48 ) has a gap end ( 50 ) proximate pivot axis ( 55 ) of increased size which is disposed between the spring sections ( 38 ) in circumferential direction (U). 
     
     
         10 . In combination with an apparatus for the manufacture of can bodies ( 11 ), said apparatus including a lower tool ( 21 ) having a hollow cylindrical deep-draw opening ( 20 ) with an exit opening ( 23 ), the improvement which comprises:
 a take-off ring ( 10 ) including an annular base section ( 32 ) by which several take-off elements ( 27 ) are interconnected,   each take-off element ( 27 ) includes a spring section ( 38 ) which extends radially inwardly from the base section ( 32 ) and has a pivot axis ( 55 ) which extends in a circumferential direction (U), each take-off element ( 27 ) includes a radially inwardly disposed transition section ( 39 ) from which a take-off tongue ( 35 ) extends transverse to the radial direction and transverse to the circumferential direction (U) and which is supported so as to be pivotable about the pivot axis ( 55 ),   the base section ( 32 ) arranged coaxially with the exit opening ( 23 ) of the deep-draw opening ( 20 ) in the lower tool ( 21 ) and releasably connected to a mounting surface area surrounding the exit opening ( 23 ).
