Abstract: A radial/axial ring rolling mill for rolling a ring has an axial rolling device and a radial rolling device. The radial rolling device includes a main roller and a roller mandrel, between which the ring can be shaped. The roller mandrel is retained in the upper region thereof on a mandrel bearing head supported in a first linear adjustment device to be able to be horizontally adjusted in such that the roller mandrel can be moved perpendicularly to the longitudinal extent thereof in the direction towards the main roller and in the opposite direction thereto. The first linear adjustment device together with the mandrel bearing head and the roller mandrel is able to be adjusted as a unit by a second linear adjustment device in a vertical manner so that the roller mandrel can be pulled out of the inner space of the ring and introduced therein.

Abstract: Construction is achieved that, together with preventing the occurrence of damage to a mandrel, is able to improve precision of the shape of a ring-shaped member after processing. A mandrel includes a pair of support shaft sections that are provided so as to be separated in the axial direction and so as to be concentric with each other, and a rolling shaft section that is concentrically provided in the axial direction between the pair of support shaft sections. One of the support shaft sections is provided in a state in which displacement in the axial direction with respect to the rolling shaft section is regulated. The other support shaft section is provided in a state in which displacement in a direction going away from the rolling shaft section is possible when a pressing force is applied in that direction.

Abstract: A ring rolling device includes a drive roller and a rotatable revolving drum, in which five mandrels are rotatably mounted. Ring blanks can be mounted around the mandrels. By rotating the revolver drum, the mandrels move towards and away from the drive roller. The revolver drum is arranged in relation to the drive roller such that by rotating the revolver drum a decreasing roll gap is formed between a mandrel approaching the drive roller and the drive roller, in which roll gap a ring blank mounted around the mandrel is rolled during the rotating of the revolver drum. The revolver drum has four rotatably mounted support rollers, said support rollers supporting the mandrel in the direction of the rotational axis of the revolving drum, such that, during the rolling process, the mandrel is located between the support rollers and the press element.

Abstract: There is provided a method for manufacturing ring-shaped members at a good yield and high production efficiency. To achieve this object, the following is performed. A single (a sequence of) forging produces a joined body formed by radially coupling four cylindrical portions with different inner diameter sizes. A cylindrical member that has the largest inner diameter size and a cylindrical member that has the third largest inner diameter size after the forging are employed as ring-shaped members without change. A rolling process is performed on respective cylindrical member that has the smallest inner diameter size and cylindrical member that has the second largest inner diameter size to obtain ring-shaped members. Thus, two sets of ring-shaped members are obtained as two sets of inner rings and outer rings.

Abstract: In the production of an internal contour with an internal arbor acting on the inner wall of a cup-shaped or annular rotationally symmetrical workpiece, expansion and length change of the workpiece are avoided during cold forming. Thus, gear components with internal teeth are produced that have greater symmetry and higher accuracy. A workpiece provided with a press fit on the outside or a prefabricated workpiece is inserted into the die, and during the cold forming is pressed tightly by friction and rotationally fixed with the rotationally driven internal arbor against the inner wall of the die. After completion of the rolling process of the profile, the workpiece is ejected with an axial ram. The internal arbor is provided with outside profiling and is cantilever-mounted and is fed axially and radially during the rolling.

Abstract: A linear ball bearing mounting flange, which is provided on at least one end of an outer cylinder of a linear ball bearing and is used for mounting the linear ball bearing on a machine or apparatus. The flange includes a flange-shaped structure having a thick wall and provided separately from the outer cylinder. The flange-shaped structure has an annular recess extending from one end surface of the flange-shaped structure along the inner peripheral surface thereof; a peripheral wall on the inner peripheral side of the recess, which has a jagged structure in which projections and recesses are alternately arranged along the circumferential direction; and a claw projecting inward from the inner peripheral wall, which is formed at the leading end of each of the projecting portions of the jagged structure. When the flange is inserted around the outer cylinder of the linear ball bearing, the claws are locked in a claw insertion hole provided in the outer cylinder. Such a linear ball bearing mounting flange, which can be simply, easily mounted on the outer cylinder of the linear ball bearing, can be manufactured at a low cost.

Abstract: 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.

Abstract: The invention relates to a wheel-body forming apparatus which is capable of forming up a high-precision wheel body having the perfect roundness, more partiuclarly, to an apparatus used for forming any of those wheel bodies such as the inner-and-outer races or pillow of bearing, or automotive gauges or sleeves for example, by applying a rolling process before eventually forming the objective material into the predetermined configuration. The apparatus related to the invention is mainly comprised of three rotative members including a shape-forming roller, a mandrel, and a supporting roller, which are respectively installed on a plane in parallel with each other. Of these, the shape-forming roller and the supporting roller are independently driven, and yet, the apparatus related to the invention is further comprised of means for numerically controlling the number of the rotation of the supporting roller relative to the number of the rotation of the shape-forming roller in accordance with the variation of the diameter of the wheel body being formed.
