Die for mechanical joining

Abstract

A die for a tool set includes a punch and a die for mechanically joining metal sheets lying flat one on top of another by shaping. An anvil and die segments together form a cavity into which the joining is carried out. The die segments are supported in a slidable manner at an angle transversely, preferably orthogonally to the cavity axis H against a spring force. A casing sleeve surrounding the die segments is essentially rectangular in cross section, open at the top and can be attached to a base body. The die segments can be supported and guided in guide slots lying parallel opposite one another in the casing sleeve. Guide mechanisms project laterally on the die segments for positive engagement in the guide slots.

1 . A die for a tool set, comprising: 
 a punch and a die structured to mechanically join metal sheets lying flat one on top of another by shaping;    an anvil;    die segments, together with the anvil, forming a cavity into which the joining is carried out and which are supported against a spring force in a slidable manner at an angle transversely to an axis H of the cavity;    a casing sleeve surrounding the die segments, the casing sleeve being essentially rectangular in cross section, open at a top and attachable to a base body;    guide slots lying parallel opposite one another in the casing sleeve which support and guide the die segments; and    guides projecting laterally on the die segments for positive engagement in the guide slots.    
   
   
       2 . The die according to  claim 1 , further comprising a separate spring supported in the base body and assigned to each die segment.  
   
   
       3 . The die according to  claim 1 , wherein the die segments are two die segments arranged opposite one another.  
   
   
       4 . The die according to  claim 2 , wherein the springs are leaf springs.  
   
   
       5 . The die according to  claim 1 , wherein the springs are attached to the base body by fasteners.  
   
   
       6 . The die according to  claim 5 , wherein the casing sleeve is attached to the base body by the fasteners.  
   
   
       7 . The die according to  claim 1 , wherein the guides are bolts insertable in the die segments.  
   
   
       8 . The die according to  claim 1 , wherein the guides are lateral guide lugs embodied in one piece with the die segments.  
   
   
       9 . The die according to  claim 1 , wherein the anvil is on the base body.  
   
   
       10 . The die according to  claim 1 , wherein the casing sleeve serves as a travel-limiting stop for the die segments.  
   
   
       11 . The die according to  claim 1 , wherein the angle is orthogonal to the cavity axis H.  
   
   
       12 . The die according to  claim 5 , wherein the fasteners are bolts.  
   
   
       13 . The die according to  claim 6 , wherein the fasteners are bolts.  
   
   
       14 . A die comprising: 
 a casing sleeve which is open at a top and attached to a base body;    guide slots lying opposite one another in the casing sleeve;    die segments supported and guided in the guide slots; and    guide mechanisms projecting laterally from the die segments to positively engage in the guide slots.    
   
   
       15 . The die according to  claim 14 , wherein the die segments together with an anvil forms a cavity with a cavity axis H and the die segments are supported in a transverse slidable manner in the casing sleeve.  
   
   
       16 . The die according to  claim 14 , wherein the casing sleeve is essentially rectangular in cross section.  
   
   
       17 . The die according to  claim 14 , further comprising springs attached laterally in the base body and which exert a prestressing force on the die segments and apply a restoring force to return the die segments to an original position after joining is completed.  
   
   
       18 . The die according to  claim 17 , wherein the springs are two leaf springs which bear against a back of the die segments and are fixed in the base body by fasteners that are driven into the base body.  
   
   
       19 . The die according to  claim 14 , wherein the guide mechanisms are one of laterally projecting lugs extending from the die segments and a plurality of bolts.  
   
   
       20 . The die according to  claim 14 , wherein the die segments are each provided with a through bore on lateral outer ends, and bolts are inserted through the bores and are accommodated in a positive manner in the guide slots.
