An auxiliary bending tool for bending machines

Abstract

The present invention relates to an auxiliary bending tool (1) associated to a body (40) provided in CNC bending machines and which provides the work piece to be bent in various shapes and which can operate together with the present bending tools (15). As an improvement, said auxiliary bending tool (1) comprises a tool carrier apparatus (20) having at least one connection protrusion (21) which can be associated onto said body (40), a tool locking unit (10) connected to an assembly surface (22), provided on said tool carrier apparatus (20), through a connection surface (16) and configured to provide locking of at least one tool (15) thereon, and at least one drive group (30) for providing forward-backward movement on an axis X (I) of the tool carrier apparatus (20) whereon said tool locking unit (10) is associated.

1 . An auxiliary bending tool associated to a body provided in CNC bending machines and which provides the work piece to be bent in various shapes and which can operate together with a present bending tool, the auxiliary bending tool comprising:
 a tool carrier apparatus having at least one connection protrusion which can be associated onto said body;   a tool locking unit connected to an assembly surface, the tool locking unit provided on said tool carrier apparatus through a connection surface and configured to provide locking of at least one tool thereon; and   at least one drive group configured to provide forward-backward movement on an axis X (I) of the tool carrier apparatus whereon said tool locking unit is associated; wherein said tool locking unit comprises:   a tool locking arm which can realize rotational movement around an axis A (III);   at least one movement element associated with said tool locking arm and which provides transferring of the movement transferred from the tool locking arm;   at least one lock element associated with said movement element; and   at least one tool locking element which provides compression and fixation of said tool by movement of said lock element in an axis Z.   
     
     
         2 . (canceled) 
     
     
         3 . The auxiliary bending tool according to  claim 1 , wherein said drive group comprises at least one drive transfer unit configured to be driven by at least one drive element and to provide movement of the tool carrier apparatus in said axis X.
