A device and method for producing a component are provided. The device or method includes steps or units for providing a first component element having a recess in or on a first surface of the first component element, and for positioning a second component element in the region of the recess. The device or method also includes a step or unit for pressing the first component element and the second component element together, and as a result forming a material fit, positive fit and/or non-positive fit between the first and the second component elements at least in the region of the recess. The positioning and the pressing can be carried out or are carried out functionally, in particular, spatially and/or temporally, in terms of equipment, separately from each other.

The present invention relates to a forging method and a forging apparatus, capable of: reducing the amount of tray plates used during the forging of materials by reducing the width from front to back of the tray plates by fixing only the rear of the materials to the tray plates for fixing the materials; and minimizing the amount of materials used, by compression-molding products by fixing, to the tray plates, the materials having a minimum size necessary for the fmal products, the present invention comprising: a press having upper and lower molds; a tray plate supply means for supplying, to the top rear of the lower mold, tray plates to be vertically movable from one side to the other side by a pitch and to be spaced from the upside of the lower mold; a punching unit provided at one side of the upper and lower molds so as to continuously punch material fixing hole parts in the tray plates; a material plate supply means provided at the front of the other side of the punching unit so as to supply material plates by a pitch to under the material fixing hole parts of the tray plates and, at the same time, form penetrating protrusion parts, which penetrate into the material fixing hole parts, on the rear top of the material plate in each pitch, which is moved by a pitch; a cutting and compressive fixing unit provided on the upper and lower molds at the other side of the punching unit so as to cut the material plates, which are inserted into the material fixing hole parts of the tray plates, by a pitch and, at the same time, allow the penetrating protrusion parts formed at the rear of the cut materials to penetrate into the material fixing hole parts, thereby compressively fixing same; and a compression molding unit provided on the upper and lower molds at the other side of the cutting and compressive fixing unit so as to compression-mold the materials being transferred.

A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (46), formed by combining a plurality of punch elements (46, 46) divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth (44, 44) at one end surface in the axial direction, to face the other end surface of the caulking section (20) in the axial direction. In this state, rolls (30a) are rotated about the central axis (α) of the hub main body (8) while pressing the other end surface of the forming punch (46) in the axial direction with a pressing surface (43) of the roll (30a) having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body (8).

A hub main body (13z) is supported by a support portion (18). At least one block (22) is engaged with a stationary flange (6) of an outer ring (2). As a support plate (21) rotates, the outer ring (2) rotates. A caulking portion (16) is formed by pressing a pressing die (20) on a cylindrical portion (31).

An end-form fitting includes a tube and an auxiliary component disposed around the tube. One of the tube and the auxiliary component is deformed to cause the auxiliary component to engage the tube in order to militate against relative movement between the tube and the auxiliary component. The auxiliary component includes an array of surface irregularities formed therein and configured to engage an outer circumferential surface of the tube to form a corrugated joint therebetween. The auxiliary component is formed to include a radially outwardly extending orientation structure for establishing a rotational orientation of the end-form fitting when being coupled to a complimentary end-form fitting.

Provided are an oil receiver (20) having an annular recess portion (52) which faces an entire circumference of an outer circumferential edge of a concave spherical portion (36), and a guide member (21) which guides lubricating oil, which has flowed out from a spherical engagement portion between a convex spherical portion (24) and a concave spherical portion (36), toward an annular recess portion (52).
