Bending die

Abstract

An object of the present invention is to provide a bending die that has a simple configuration and is capable of bending a rod-shaped body in a three-dimensional XYZ direction quickly and reliably. The bending die includes XY-plane forming dies that are to be clamped in an X direction to bend the rod-shaped body in an XY plane, and Z-direction forming dies that are to be clamped in a Z direction to bend the rod-shaped body in the Z direction, wherein when both the XY-plane forming dies and the Z-direction forming dies are clamped, a cavity that forms the rod-shaped body bent in the three-dimensional XYZ direction is defined therebetween.

1 . A bending die used for forming a rod-shaped body bent in a three-dimensional XYZ direction, the bending die comprising: an XY-plane forming die that is clamped in an X direction to bend the rod-shaped body in an XY plane; and a Z-direction forming die that is clamped in a Z direction to bend the rod-shaped body in the Z direction, wherein, when both the XY-plane forming die and the Z-direction forming die are clamped, a cavity that forms the rod-shaped body bent in the three-dimensional XYZ direction is defined therebetween. 
     
     
         2 . The bending die according to  claim 1 , wherein the XY-plane forming die is a pair of forming dies clamped in the X direction, and forming surfaces for bending the rod-shaped body in an XY direction are formed on respective plate surfaces of the forming dies that face each other. 
     
     
         3 . The bending die according to  claim 2 , wherein, when the pair of XY-plane forming dies is clamped, the pair of XY-plane forming dies defines a cavity between the forming surfaces facing each other, a width of the cavity being approximately equivalent to an outer diameter of the rod-shaped body to be bent. 
     
     
         4 . The bending die according to  claim 1 , wherein the Z-direction forming die is a pair of forming dies clamped in the Z direction; forming recess portions are formed at facing tip surfaces of the pair of forming dies; and the forming recess portions define a cavity for forming the rod-shaped body bent in the three-dimensional XYZ direction between the forming recess portions when the pair of forming dies are clamped.
