Abstract
A die on which a fabricated body to be press-formed is mounted includes a mounting surface on which the fabricated body is mounted, a punch that forms a hole in the fabricated body, a first receiving portion that at least partially receives the punch, and a second receiving portion which is formed in the mounting surface and receives a deformed portion of the fabricated body that is formed by the pressure of the punch on the fabricated body.
Claims19
A die on which a fabricated body to be press-formed is mounted, comprising:
- a mounting surface on which the fabricated body is mounted;
- a first receiving portion that at least partially receives a punch that forms a hole in the fabricated body;
- and
- a second receiving portion which is formed in the mounting surface and receives a deformed portion of the fabricated body that is formed by the pressure of the punch on the fabricated body.
A press-forming tool set comprising:
- a die on which a fabricated body is mounted;
- a punch that forms a hole in the fabricated body;
- a mounting surface that is formed on the die and on which the fabricated body is mounted;
- a first receiving portion which is formed in the die and at least partially receives the punch;
- and
- a second receiving portion which is formed in the mounting surface and receives a deformed portion of the fabricated body that is formed by the pressure of the punch on the fabricated body.
A press-forming method for forming a fabricated body using a die and a punch, comprising:
- mounting the fabricated body on a mounting surface of the die;
- pressing the fabricated body mounted on the die with the punch arranged in a position corresponding to a first receiving portion formed in the die;
- and
- receiving a deformed portion of the fabricated body, which is formed by the pressure of the punch on the fabricated body, in a second receiving portion formed in the mounting surface of the die.
A method of manufacturing a bumper having a hole using a die and a punch, comprising:
- mounting the bumper on a mounting surface of the die;
- pressing the bumper mounted on the die with a punch arranged in a position corresponding to a first receiving portion formed in the die;
- and
- receiving a deformed portion of the bumper, which is formed by the pressure of the punch on the bumper, in a second receiving portion formed in the mounting surface of the die.
