METHOD AND DEVICE FOR PRESSING A GREEN COMPACT |
| 摘要 |
The invention relates to a method for pressing a green compact (1) for producing a sintered molded part from a sintering powder, according to which the sintering powder is filled into a mold cavity (43a) of a die (43), and then the sintering powder is pressed by at least one punch, which is pushed at least partly into the mold cavity (43a), to form a green compact (1), wherein to form an undercut in the green compact (1) a portion of the sintering powder is pushed by a punch out of a first plane of the die (43) by forming an opening (11) in the first plane in pressing direction into a second plane of the die (11) different from the first plane. The invention also relates to a device (12) for performing said method and a correspondingly produced sintered molded part. |

1. A method for pressing a green compact (1) for producing a sintered molded part from a sintering powder, according to which the sintering powder is filled into a mold cavity (43a) of a die (43), and then the sintering powder is compressed by at least one punch, which is pushed at least partly into the mold cavity (43a), to form a green compact (1), wherein to form an undercut in the green compact (1) a portion of the sintering powder is pushed by a punch out of a first plane of the die (43) forming an opening (11) in the first plane in pressing direction into a second plane of the die (11) different from the first plane. |
