Abstract

PURPOSE:To increase the rising rate of a material and to execute precise working by revolving a die as the axial line of a work at the specific inclination and executing plastic working corresponding to the shape of the die with moving at least one part of the die and work on the plane orthogonal with the axial line. CONSTITUTION:A driving gear 11 is turned, a supporting body 10 is turned via an annular gear 9 and the eccentric amt. of a spherical connection piece 25 from an axial line CL is set constantly. Also, inner and outer eccentric turning bodies 12, 13 are turned by turning driving gears 16, 22 and the die on a die loading part 27 is arranged on the axial line of a turning shaft 2 and abutted to a work W as well. And, the turning shaft 2 is turned in the state of holding the work W at the specific position on a work supporting face S. Then, a holder 24 is revolved around the axial line CL of the turning shaft 2. A plastic working is thereby executed on the work W according to the shape of the forming hole of the die.
