| 摘要 |
The invention relates to a hypocycloidal plastic cold-pressing automatic machine designed for manufacturing metal parts. According to the invention, the cold-pressing automatic machine ensures the drive of a mobile part in relation to a fixed part of a plastic deformation tool by comprising a planetary gear (B) consisting of a fixed bed (12) with two satellites (A) rotating therein, said satellites being supported by a central shaft (6). Each of said satellites (A) is provided with a concave groove (a) along its circumference, and the toothed wheels (15) mounted on the body (13) of each satellite (A) are located at different levels. Two or four antipodal cavities (c), representing the pressing posts, are cut in the bed (12).
