Spring Manufacturing Machine

Abstract

A spring manufacturing machine comprises a coiling mandrel fixed to a wall and protruding from the wall, and a cutting device that has a slider movable in a direction inclined with respect to the axis of the coiling mandrel and a blade attached to the slider, and cuts a bent wire in cooperation with the coiling mandrel. Preferably, the coiling mandrel protrudes orthogonally to the wall, and the cutting device is attached to the wall in a posture inclined with respect to the wall.

What is claimed is: 
     
         1 . A spring manufacturing machine comprising:
 a coiling mandrel fixed to a wall and protruding from the wall; and   a cutting device that has a slider movable in a direction inclined with respect to an axis of the coiling mandrel and a blade attached to the slider, and cuts a bent wire in cooperation with the coiling mandrel.   
     
     
         2 . The spring manufacturing machine according to  claim 1 ,
 wherein the coiling mandrel protrudes orthogonally to the wall,   the cutting device is attached to the wall in a posture inclined with respect to the wall, and   an angle of inclination of the cutting device with respect to the wall is not more than 30 degrees.   
     
     
         3 . The spring manufacturing machine according to  claim 1 ,
 wherein an adjustment mechanism that adjusts the posture of the cutting device is provided.   
     
     
         4 . The spring manufacturing machine according to  claim 1 , wherein
 the blade has a parallel portion parallel to the axis of the coiling mandrel, and   the wire is sandwiched between the parallel portion and the coiling mandrel to be cut.
