Abstract: The invention relates to a method for the production of a rolled edge from an edge section (11) of a tube, wherein a flanging die is driven onto the edge section and flanges it into a roll. According to the invention, an initial area (14) of the edge section (11) is previously rolled in a positive fit manner by means of a forcibly controlled tool (30). This prevents buckling of the initial area (14), which has a controlled geometry as a result of rolling. The novel method is preferably used in the production of valve seats in so-called aerosol domes (10) for spray cans.

Abstract: The invention relates to a so-called spring cushion (5), for the ejection of moulded pieces (4) from a moulding tool (3), with a plunger (6), moving in a guide tube (9) within the moulding tool and loaded in the ejection direction (14) by means of a spring (15). According to the invention, the spring (15) is embodied as a draw spring, in particular as a spiral draw spring. Considerably longer service life can be achieved as draw springs do not have radial deflections on loading.

Abstract: The present invention relates to a device on a press and to a method for incrementally conveying workpieces in a longitudinal direction from a receiving station through at least one tooling station of the press with the aid of conveying means for the workpieces, which conveying means are moved back and forth in cycles and in synchrony with the movement of the press in the longitudinal direction, as well as in a transverse direction substantially perpendicular thereto in order to grip or release the workpieces. The conveying means are here moved in the longitudinal direction by means of an external drive unit which is merely synchronized with the movement of the press. The motor-powered external drive unit is mechanically coupled to the conveying means in such a way that the conveying means can be moved back and forth without reversing the rotation of the external drive unit.

Abstract: The invention relates to a tubular rivet connection between at least one first (1) and one second metal sheet (2). According to the invention, the tubular rivet (3) is made from the metal of the first metal sheet (1) by deforming, in a drawing direction (Z), the edge area of a first hole (4) located in the first metal sheet (1) into a second, larger hole (5) located in the second metal sheet (2), whereby the second hole (5) located in the second metal sheet (2) is, in particular, gradually enlarged with regard to its diameter in the drawing direction (Z). The invention provides that the tubular rivet (3) is shorter in length in the drawing direction (Z) than the thickness of the second metal sheet (2). To this end, the thickness tolerance of commercially available metal sheets is taken into account and damages to the tools and/or the formation of chips is/are prevented.

Abstract: The invention relates to a method for producing lamella packets (60, 70) of the type normally used in adjustable steering columns in automobiles and which comprise a soft lamella (71) made of soft sheet metal material and at least one layered hard lamella (71) placed on top of said material. The lamella (71, 74) are connected by at least one rivet made of soft lamella (71). The method is characterized by the use of presses (110, 120) positioned one after the other. A soft lamella (71) is formed and stamped out of a strip (111) of said softer material in the first press (110) at a rate dictated by the press (110). Soft lamella (71) produced in this matter are transported to the second press (120). At least one hard lamella (72, 74) is completely formed in a second press (120) from a band (121) of harder sheet material and then stamped. Said hard lamella is placed over a soft lamella (71) and a rivet connection is produced.

Abstract: A steering device for motor vehicles has a steering shaft that is guided by a guide box (3) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface (8) along the axis of the shaft (1) which allows for a displacement path (20) with respect to the chassis (18) in case of a collision. A clamp (17) is provided for axial retention of the console (6) in an initial position of the displacement path (20). In this way at least one part of the clamped surface is slanted in relation to the vertical clamping device so that the clamping surfaces can move away from each other when the steering shaft is displaced and clamping is reduced.

Abstract: The invention relates to a device for progressively transporting workpieces in a longitudinal direction from a receiving station, through at least one processing station of a press, including transporters for the workpieces, where the transporters are moved back and forth in a longitudinal direction, cyclically and in synchrony with the movement of the slide of the press, and in a crosswise direction perpendicular to the longitudinal direction for picking up and releasing the workpieces. The transporter may be driven in the longitudinal direction by an external drive that is synchronized with the eccentric shaft of the press by signaling. The movement of the transporters for releasing the workpieces in the crosswise direction is derived from the movement of the press slide by direct mechanical coupling.

Abstract: A sheet feeder system for a sheet-fed printing press includes a device for causing a sheet pile to sag at least partly in at least an upper region thereof, and at least two contact elements disposed in mutually spaced-apart relationship on an upper side of the sheet pile and having respective contact surfaces for pressing against the upper side of the sheet pile at least partly or temporarily, at least one of the contact elements being drivable so as to move the respective contact surfaces pressing against the upper side of the sheet pile towards and away from one another, respectively, for forming an interspace between the uppermost sheet of the sheet pile and a sheet immediately therebelow, and a method for individually separating sheets.

Abstract: Punched and bent parts (1, 2, 3), manufactured by non-cutting shaping, are assembled to a rigid box by using exclusively mutual riveting, optionally in part also spot welding, of the material of the punched and bent parts, thus without any additional material requirements. The parts (13) serving for bearing the steering shaft (15) are high precision pieces also obtained by non-cutting shaping. A very efficient, high precision manufacturing is thus achieved free from any finishing treatment and without auxiliary means for the connection of the punched and bent parts.

Abstract: Strips which are to be worked in a forming tool are taken out of a magazine and deposited on a guide at which by means of a finger rod with elastic catchs they are guided to the tool and stepwise advanced through said tool. By means of the programmable driving for the finger rod, this finger rod can execute strokes in any direction and in any different dimensions in order to guide the strips in the forming tool and for displacing them stepwise through the tool. The stripfeeder is of simple construction and it can be programmed for the most different requirements in that only the driving will be correspondingly programmed.

Abstract: Workpieces are transported step-by-step by means of transport bars which are provided with grippers and which are longitudinally and transversally displaceable only in cyclic relation to the reciprocating movement of a press. The transport bars have the configuration of hollow profiles which are rigid with respect to bending and torsional stresses, and their ends are rigidly constrained and guided by means of angle brackets and by means of longitudinal guidings and transversal guidings both of which are free of play. Thus, a particularly rigid and a relatively lightweight construction results which allows high working cadences.

Abstract: The process of the present invention allows for the manufacture of lacquered aluminum or tin-plate rings which have the inner edge thereof bent over outwards so that they are suitable for the closures on cans for foodstuffs. A ring blank made of lacquered sheet is pre-shaped by deep drawing to form the curvature needed for bending over the inner cut edge. The final shaping of the pre-shaped blank into a ring for a can lid takes place, after stamping out the opening, by stretching and bending over the cut edge. When a tear-back membrane is sealed on to the bent-over edge, the ring is suitable as an easily opened closure for cans for foodstuffs.

Abstract: The pre-fabricated pouring outlet in a lid for cans containing carbonated drinks lies basically at an angle of 0.degree. or 90.degree. to the rolling direction of the sheet from which the lid is made. The surface of the lid features at least one ring-shaped stiffening groove which points towards the can interior, is concentric with the periphery of the lid and is interrupted in the region of the pouring outlet. The diameter of the groove is 65-80% of that of the nominal diameter of the can.The stiffening groove raises the resistance of the lid towards pressure from inside the can by about 10%. This means that, when manufacturing a lid which has to withstand a specific pressure from inside the can, and using the same material, the thickness of the lid can be reduced to save material.
