Can, And A Method For Producing Same

Abstract

The invention relates to a method for producing a can ( 1 ) which is formed from a can section ( 10 ) and a flange section ( 20 ), a base ( 13 ) and a lateral wall ( 11 ) being designed on said can section ( 10 ), and said can section ( 10 ) being deep drawn and brought to a target geometry with a defined wall thickness by means of flow-running said lateral wall ( 11 ). The invention suggests that, on said lateral wall ( 11 ), an interface ( 12 ) is formed with a material thickness greater than the wall thickness of the lateral wall ( 11 ), the flange section ( 20 ) being able to be connected to the can section ( 10 ) at this interface ( 12 ), said can section ( 10 ) being connected to the flange section ( 20 ) by a sealing seam ( 30 ), and a force which acts upon the can section ( 10 ) in the direction of the can section ( 10 ) base ( 13 ) being transmittable not across said sealing seam ( 30 ) but rather across a form-fitting connection which is formed by the interface, from said can section ( 10 ) to the flange section ( 20 ).

1 . A method for producing a can which is formed from a can part and a flange part, wherein a base and a lateral wall are formed on the can part, and wherein the can part is deep drawn and made into a target geometry with a defined wall thickness by virtue of the lateral wall being flow formed, wherein the lateral wall has formed on it an interface with a material thickness which is greater than the wall thickness of the lateral wall, wherein the flange part can be connected to the can part at the interface, wherein the can part is connected to the flange part by a sealing seam, and wherein a force acting on the can part in the direction of the base of the can part can be transmitted from the can part to the flange part not via the sealing seam, but via a form-fitting connection formed by the interface. 
     
     
         2 . The method as claimed in  claim 1 , wherein the interface has formed on it a shoulder, against which the flange part, as a separate machine element, can be brought into abutment in a defined orientation. 
     
     
         3 . The method as claimed in  claim 2 , wherein a force which acts on the can part can be transmitted to the flange part via the shoulder. 
     
     
         4 . The method as claimed in  claim 1 , wherein, following the flow forming and the formation of the interface, the flange part is fitted onto the can part, in particular from the side of the base of the can part. 
     
     
         5 . The method as claimed in  claim 1 , wherein a sloping surface is formed on the interface at the transition to the lateral wall, and a cylindrical lateral sub-surface is formed thereon adjacent to the sloping surface. 
     
     
         6 . The method as claimed in  claim 1 , wherein, following the deep-drawing operation, during the flow forming of the lateral wall the wall thickness is brought to 1 mm at the tolerance of less than 1/10 and the lateral wall is made into a cylindrical geometry. 
     
     
         7 . A can having a can part and a flange part, wherein the can part has a base and a lateral wall, and wherein the can part is a deep-drawn part of which the lateral wall is flow formed and has a defined wall thickness, wherein the can part has an interface with a material thickness which is greater than the wall thickness of the lateral wall, wherein the interface forms a bearing for the flange part, wherein the can part and the flange part are connected to one another via a sealing seam, and wherein a force acting on the can part in the direction of the base of the can part can be transmitted from the can part to the flange part not via the sealing seam, but via a form-fitting connection formed by the interface.
