61 | Machine for making star nails | US782405 | 1997-01-14 | US5836826A | 1998-11-17 | John Haraminac |
A machine makes nails having a star-shaped transverse cross-section by sequentially feeding conventional nails into a form roller station defined by a plurality of form rollers that are radially arrayed with respect to a centerline of the nails. Circumferentially spaced notches formed about the periphery of each form roller engage the heads of the conventional nails as the form rollers rotate and pull the nails into forming relation with the form rollers. The notches also prevent formation of the nail heads. A plurality of circumferentially spaced concavities formed in the form rollers prevents forming of the work-hardened points of the nails. The nails are sequentially delivered from a bowl feeder to an indexer that inverts the nails. A pair of rotatably mounted augers transfer the nails from the indexer to a nail-gripping device that holds each nail until its head is engaged by the nail-engaging notch in each of the form rollers. The form rollers are rotated by a gear train that begins with a ring gear rotated by a motor, and the gear train enables adjustment of the rotational phase of the form rollers so that they may be maintained in rotational phase with one another. | ||||||

63 | Apparatus for rolling a ring-shaped work | US443420 | 1995-05-18 | US5605068A | 1997-02-25 | Takao Yamasoto; Hirokazu Ishiyama |
A work 12 is selectively loaded one of forming portions 20, 22, and so on, which are formed on a mandrel 18. Then, the work 12 is pressed between the selected forming portion and a forming roll 10 and rotated together with the forming roll 10 and the mandrel 18 in this state, thereby rolled and formed a groove on its inner surface. The mandrel 18 is provided movably in its axial direction, and the forming portions 20, 22, and so on, are subsequently selected for rolling the work 12 step by step. After finishing the rolling, the work 12 is unloaded from the mandrel 18, guided by a work guiding passage, and is supplied to the sizing device 120, wherein the work 12 is pushed into a die 121 and sized the outer diameter thereof. | ||||||

65 | Apparatus and process permitting the cold forming of grooves on the wall of a revolving part | US956508 | 1993-01-21 | US5339669A | 1994-08-23 | Michel Cretin; Jean-Paul Lespour; Charles Marcon |
The apparatus and process according to the invention relate to the cold forming by rolling of revolving parts (7).The apparatus comprises two identical milling wheels (9A, 9B) arranged symmetrically with respect to the part (7) to be formed and performing the same rotation movement at speed Vm and progressively moving towards the axis of the part to be formed (X1--X1). The part (7) performs a rotation movement at speed Vp such that Vp=Vm.multidot.N1/N2, N1 being the number of grooves on each wheel (9A, 9B), N2 the number of grooves to be formed on the part (7). An initial setting makes it possible to bring about coincidence between the grooves formed by each of the milling wheels on the part (7).The apparatus and process make it possible to obtain high precision parts. | ||||||
66 | Forming machine with multiple work stations | US645372 | 1984-08-29 | US4574605A | 1986-03-11 | Ronald R. Stein |
The forming machine includes a load station adjacent one end, an unload station adjacent the other end and a first work station, turnaround station and second work station spaced longitudinally in succession between the load and unload stations along a workpart flow path. Each work station includes a rotatable spindle fixed in position on one side of the flow path and a tailstock with a workpart support slidable toward the spindle transversely of the flow path. An overhead transfer mechanism is slidable along the flow path and carries multiple workpart transfer members such as grippers to transfer workparts successively from one station to the other along the flow path. First and second pairs of forming tools are spaced longitudinally to cooperate with the first and second work stations and are slidable longitudinally and simultaneously in engagement with first and second workparts rotatably and transversely supported at the respective work stations between the respective spindle and tailstock. The turnaround station is operable to permit opposite ends of a workpart such as a solid shaft to be formed by the forming tools. | ||||||

The invention relates to a method for producing metal items from metal blanks. The metal blank is positioned between two roller surfaces of two rollers, these roller surfaces being opposed and having means for being rolled out against each other from a starting position to an end position. A negative mold of the metal item to be produced is created with at least one recess in a roller surface. The process of positioning the metal blank in the starting position of the rollers takes place in the area of the recess. The rollers are then rolled out against each other from the starting position to the end position, the metal blank being shaped into the metal item by cold-forming as the rollers roll out; and the formed metal item is removed from the rollers. The invention is characterized in that the recess is configured with a variable depth curve in the directions parallel to a roller axis, at least in a partial area, and in the rolling-out direction of the rollers. | ||||||
