Abstract

A ROTARY FORGING APPARATUS COMPRISES A FIRST ROTARY RAM L30L)HAVING A CONICAL PRESSING SURFACE AND A SLANTING ROTARY AXIS, A SECOND ROTARY RAM (302) FACING THE FIRST RAM (301) AND HAVING A VERTICAL ROTARY AXIS, AND A SHAPING ROLLER EQUIPPED BESIDE THE RAMS. THE APPARATUS FORGES A PRODUCT FROM A MASS OF MATERIAL WORKPIECE(L0) BY SANDWICHING THE WORKPIECE (L 0) BETWEEN THE FIRSTRAM (301) AND THE SECOND RAM(302), PRESSING THE WORKPIECE(L0)WITH THE RAMS WHICH ROTATE SYNCHRONOUSLY, THINNING THE WORKPIECE(L0) INTO THE DISC PART(L) OF A PRODUCT, PRESSING THE EXCLUDED MATERIAL OUT OF THE RAMS WITH THE SHAPING ROLLER AND THE RAMS AND SHAPING INTO THE RIM PART. THIS INVENTION PROVIDES A ROTARY FORGING APPARATUS WHICH CAN PREVENT A GENERATION OF CRACKS OR FLASHES ON THE DISC PART(1)OR THE RIM PART(LL) WHEN THE APPARATUS FORGES A WHEEL HAVING A RIM PART(LL)WHICH CONSISTS OF A SMALL RIM PART AND A LARGE RIM PART. THIS INVENTION PROVIDES A RIM-SHAPING SURFACE AROUND THE PRESSING SURFACE OF THE SECOND RAM(302) FOR SHAPING A SMALL RIM AND AN ANNULAR WALL (32)STANDIND OUT TOWARD THE FIRST RAM(30L)AT A PERIPHERAL EDGE OF THE RIM-SHAPING SURFACE FOR RESTRAINING AND SHAPING AN END OF THE SMALL RIM. A BOTTOM SURFACE OF THE SHAPING ROLLERL2)COMES INTO TOUCH WITH OR COMES VERY CLOSE TO A TOP FACE OF THE ANNULAR WALL (32). (FIGURE 7)
