摘要： The invention relates to a method for producing an elastic articulation (1), one end of which is formed by heading with teeth marked (23) in relief. According to the invention, the riveting die is provided with teeth. Said riveting die teeth form cavities (24) which are interspersed with teeth marked on one end (17) of the articulation. In this way, fewer teeth are produced and the correct indexing of the riveting die is guaranteed during the successive revolutions thereof. The blocking of the elastic articulation against the sheet metal side of a vehicle chassis is improved owing to the fact that there are fewer teeth.

摘要： Housing blocks designed to accommodate hydraulic components are well known. Such housing blocks have hydraulic fluid ducts formed by holes to interconnect the components. According to the invention, material of the housing block (2) is deformed at the entrance of the hole in a substantially longitudinal direction of the hole (4) using a wobbling tool. Once the wobbling tool (5) is inserted in the housing block (2), an orifice (10) is made in the area of the entrance of the hole (4) that is initially narrower than the diameter of said hole (4). When wobbling is continued, said orifice (10) finally becomes narrower and disappears. Afterwards, the material causing increased narrowing of the orifice and the subsequent disappearance of said orifice, forms a closure (12) that can be economically produced. Thus, the provision of closing bodies according to prior art and of assembly devices is no longer required.

摘要： A hypoid ring gear for differential is produced by the steps of upset-forging a round bar blank (W1) heated to a predetermined temperature to forma first disk-like intermediate article (W2), die-forging said first intermediate article (W2) to form a second intermediate article (W3) in the form of a bottom-closed annular body which is smaller in inner and outer diameters and larger in axial thickness than the end product, punching out the bottom (W3') of said second intermediate article (W3) to form a third intermediate article (W4) in the form of a bottom-opened annular body which is smaller in inner and outer diameters and larger in axial thickness than the end product, shot-blasting said third intermediate article (W4) to remove the scale and reheating it to a predetermined temperature and ring-rolling it to form a fourth intermediate article (W5) in the form of a crude product which is somewhat smaller in inner and outer diameters and somewhat larger in axial thickness than the end product, orbitally forging said fourth intermediate article (W5) to form a fifth intermediate article (W6) having hypoid teeth (9) formed therein by orbital forging, and normalizing and shot-blasting said fifth intermediate article (W6) to effect normalization and scale removal and then punching out the inner burr (W6') which is formed on said fifth intermediate article (W6) during tooth forming operation based on orbital forging and cold-coining it, thereby forming the end product (W7).

摘要： The invention relates to a process for ring rolling the teeth of bevel gears, preferably hypoid-toothed bevel gears, in a closed die, in which use is made of a pretreated blank of which the outline outside the shaping region of the profiled tools already substantially corresponds to the finished outline, the outline to the shaped is heated before rolling, the shaped tool together with at least one closing device rotating with it forms a closed space with respect to the heated outline of the tool, shaping is performed between two rotating tools and the bevelled upper tool is set in the direction of its line of symmetry. The invention proposes that the closing device is axially shifted along the line of symmetry of the upper shaped tool during the rolling process. The tooling of the invention for implementing the process consists of two rotating tools which are inclined towards each other in accordance with the outlines of the bevel gear to be produced. The upper shaped tool is axially adjustable towards its line of symmetry and the outline of the workpiece to be shaped is arranged during the rolling process in a closed space formed by the upper shaped tool and at least one closing device rotating with it. The closing device (4, 5) consists of an inner (4) and an outer (5) band which can be moved in the adjusting direction in relation to the upper shaped tool (3) during the rolling process.

摘要： The invention concerns a process for manufacturing annular work pieces from metal with a profiled cross-section, preferably with external helical gearing, and a rolling facility for carrying out the method. It is proposed that a) forming should be done with two rotating tools; b) the latter should be configured preferably at the same angle to the work piece; c) at least one tool should be fed perpendicularly to the work piece; and d) the die in a mount which is fixed at least axially should rotate about an axis of rotation extending in the tool feed direction. The rolling facility consists of a) two tools (1, 2, 21, 22) which are inclined relative to the work piece (10) preferably at the same angle, at least one tool (1, 2, 21) being capable of displacement in the tool feed direction (12, 20); b) a die (5) with inner gearing which with a closure device forms a closed chamber for the work piece, the die depth matching the width of the teeth; and c) a mount which is fixed at least axially and in which the die (5) is mounted so as to be capable of rotating about an axis extending in the tool feed direction (12, 20).
