Abstract

PURPOSE: To provide a pressing machine wherein high quality pressing with a right-angled cut plane and a small-sized broken plane is made practicable in bar cutting by minimizing the engaging amount of a punch with a die by means of a die having a die hole smaller than the punch width.
CONSTITUTION: The pressing machine comprises a punch 6 having a guide section b, a pad 7 for pressing a bar material, a plate 8 with which the bar material comes into contact, and a die 9, a die hole C being smaller than the width of the punch 6. Then, products 11 after shearing are strongly fitted to the die hole. Since the engaging amount (d) of the punch 6 with the die 9 is minimized, the top product 11 positions at a distance (d) below the upper surface of the die 9. In this conditions, a bar material 10 is brought into contact with the plate 8 and the punch 6 being caused to fall while pressing the material by the pad 7. Just after an edge of the punch 6 bites the bar material 10, the punch 6 receives the pressure of the products 11 strongly fitted to the die hole.
