Abstract

PURPOSE: To produce the straightening die which does not require any large space in mounting at low cost by forming the straightening die used in combination with a forming die for cold working by a plate-form body which is fixed at the circumferential edge part and piercing a die hole in the central part of the plate-form body.
CONSTITUTION: A straightening die 3 composed of a plate-form body is fixed to side end face of the die hole relief part 2c of a forming die 1 for cold extrusion working having a die hole 2 by means of a plurality of knock pins 5. The straightening die 3 is constituted by the plate-form body of a carbon steel plate or the like of about 3W10mm thick and is provided with a die hole 4 matching to the die hole 2 of the forming die 1 on its axial extension line at its centeral part. This die hole 4 is segmented to a shear drop part 4a by pressing as well as shearing face part 4b and fracture face part 4c. The shearing face part 4b performs straightening action substantially. The blank being extrusion-worked enters the inside of the die hole 2 from the lead-in part 2a of the forming die 1 then enters the die hole 4 of the straightening die 3 part the relief hole 2c. At the time when is passes said hole, its bending is removed.
