Abstract
PURPOSE: To easily manufacture the titled product without deformation in the bottom section, by forming rough surface installed at a level which is lower than the stepped part of the collar section, from a solid metallic rod, to a bottom part and installing a corner at the bottom part, then, rolling the rough surface while the end part of the collar section is pressed.
CONSTITUTION: A rough surface A2 in which the position of the bottom of a hole 1 is set to a level lower than a stepped part of a collar section 2, by press forming a solid metallic rod. Then, this surface A2 is fitted into a die 5. After the rough surface is fitted, a punch mechanism is lowered, and a center punch 3 is pushed in the hole 1 of the rough surface 2. A corner is installed at the bottom part of the hole 1 by pressing the tip of the punch 3 to the bottom. Then, the tip of a sleeve punch 4 is made to contact to the end face of the collar section 2 of the surface, and then the punch 4 is lowered and the surface A2 is pressed downward. When the surface A2 is pressed downward, the collar section 2 held in a guide hole 5a is pushed in a forming hole 5b and a rolling is performed on the collar section 2. In this case, the punch 3 is free from the pressing and carries out a guide function. Therefore, a bottomed hollow metallic product A3 having a hole of a uniform diameter 1a is manufactured.
