摘要:
The invention relates to a method for controlling the material flow during the deep-drawing of sheet metal, the edges of the sheet metal (1) being compressed between at least one upper stopper (13) and at least one lower stopper (6, 7) during the deep-drawing process, with a controllable elastic force (8, 9). The invention also relates to a corresponding deep-drawing tool. According to the invention, a Z-shaped blocking step (11) is stamped into the edge (1a) of the sheet metal when the upper and lower stoppers (13, 6, 7) are closed, the basic shape is then produced by deep-drawing, maintaining the blocking step (11) and completely blocking the sheet metal between the stoppers, said sheet metal (1) being outwardly stretched, and the blocking step (11) is then reduced in terms of height, facilitating the outward displacement of the sheet metal towards the outside. The deep-drawing tool is characterised in that the lower stopper consists of an inner stopper (6) and an outer stopper (7), which are arranged in an annular manner on the edge of the sheet metal (1) and can be displaced in relation to each other in the holding direction.

The invention relates to a method and device for joining coated metal sheets by means of laser welding according to which the metal sheets (1, 2) are placed one on top of the other so that the marginal strip (4) of one metal sheet (2) protrudes over the marginal strip (3) of the other metal sheet (1), and the marginal strips (3, 4) are pressed together at least in areas and are joined by means of a laser beam (14) oriented transversal or essentially transversal to the plane of the marginal strips (3, 4). The degassing of the coating material is easily made possible when, during laser welding, the protruding marginal strip (4) is pushed away from the other marginal strip (3) in order to form a degassing space (10).
摘要:
Die Erfindung betrifft eine Mehrfachschraubeinrichtung zum Befestigen eines Kfz-Rades an einer Radnabe oder dergleichen, insbesondere im Zuge einer Montagelinie für die Fahrwerksmontage von Kraftfahrzeugen, wobei mehrere Winkelschrauber (10) zwischen einer Grundplatte (1) und einer Kopfplatte (2) angeordnet sind, deren abgewinkelte, mit Steckschlüsseleinsätzen (11) versehene Enden (9) sich durch Löcher (8) der Grundplatte (1) erstrecken und die Grundplatte (1) eine Halteeinrichtung für das Kfz-Rad aufweist. Damit mit der Mehrfachschraubeinrichtung Kfz-Räder mit unterschiedlichen Lochkreisdurchmessern verschraubt werden können, soll jeder Winkelschrauber (10) auf einem in Bezug auf die Radachse (16) radial verstellbaren Führungsschlitten (13) befestigt sein und sollen die Löcher (8) der Grundplatte (1) eine radiale Verschiebung der Winkelschrauber (10) zulassende Abmessungen besitzen.

The invention relates to a linear motor for a linear drive mechanism of a magnetic levitation transport system. Said linear motor comprises a plurality of inductor supports (15) which are arranged in a row and which have grooves (14) crosswise to the longitudinal direction, said grooves being substantially equal distances apart from each other; and at least three linear motor lines (1, 2, 3), which are wound into windings (16) in a meandering shape and which are located in the grooves (14) in sections. Said coils (16) have winding heads (16.1, 16.2, 16.3) situated a distance (A) apart. The invention solves the technical problem of producing the windings continuously and economically by providing that the lengths (A') of the winding heads (16.1', 16.2', 16.3') of the at least three linear motor lines (1, 2, 3) are extended at a point of discontinuity (100) between two adjacent inductor supports (15).

Eine Vertikaldrehmaschine hat zwei vertikal angeordnete Werkstückspindeln (12, 13) und zwei Werkzeugträger (7, 8), welche auf Führungen (5, 6; 2) in Z-Richtung und X-Richtung verfahrbarer Kreuzschlitten (3, 4) angeordnet sind. Die Werkstückspindeln (12, 13) sind auf einem Führungsträger (9) derart verfahrbar, dass sie aus einem Arbeitsbereich (20) heraus horizontal in Y-Richtung quer zur horizontalen Verfahrbarkeit des Werkzeugträgers (7, 8) verfahren werden können.

The invention relates to a clamping frame for automobile side parts (7) comprising a plurality of clamping elements (6) for clamping automobile side parts (7). Said frame includes two substantially vertical outer connector supports (2) for positioning and blocking units (3) for fixing in a welding station and a docking unit (5) for a means of transport. Said clamping frame that is easy to assemble and maintain is characterized in that both outer connector supports (2) are only connected by a torsion and bend resistant support (1) that extends substantially in horizontal direction, the clamping elements (6) and the docking unit (5) being fixed thereto, wherein the height of the support (1) in a projection towards the automobile side part (7) is smaller that said part (7).

The invention relates to a method for producing doors, hoods or single parts made of sheet metal in automotive bodyshells, whereby flat plates of sheet metal (6) are shaped as semi-finished products in forming units or forming lines (5), the shaped sheet metal is assembled in the bodyshell line with other sheets of metal, preferably by means of nesting, gelling, folding and optionally welding. The invention is characterised in that the plates are shaped in integrated-tool single-purpose forming cells (4) at the same speed as the manufacture of the bodyshells and the pressed parts thus formed are conveyed directly (i.e. without intermediate storage) to the bodyshell (3) cell or the bodyshell line (1) where they are assembled with other pressed pieces or other metal sheets or directly assembled with the body (2).

Ein Werkzeug für den Anbau an Manipulatoren zur Handhabung und/oder Bearbeitung von Werkstücken vzw. von Gußteilen, mit einem am Manipulator angeordneten Grundkörper (2) und einer Greifzange (1), die aus relativ zueinander bewegbaren, in dem Grundkörper (2) schwenkbar gelagerten Greifarmen (5, 6) besteht, soll derart weiterentwickelt werden, daß der Einsatzbereich eines mit einem solchen Werkzeug ausgerüsteten Manipulators vergrößert wird. Erfindungsgemäß weist hierfür ein Werkstückaufnahmeelement (14) eines Greifarmes (6) des Werkzeuges zueinander beabstandete Haltestege (12, 13) auf, die derart positioniert sind, daß das am anderen Greifarm (5) ausgebildete Werkstückaufnahmeelement (14) in den Zwischenraum zwischen den Haltestegen (12, 13) schwenkbar ist.
摘要:
The invention relates to a process for cleaning granular materials like mill scale and oil-contaminated minerals of attached fatty substances, especially oil, in which, for the purposes of surface cleaning, the materials are subjected to a solid-body mechanical stress (attrition 2) and conditioning (4) with the addition of liquid or washed with a detergent possibly containing surface-active reagents (tensides) and dispersants in a flotation plant (5). According to the invention, it is proposed that the materials be treated in a single or multi-stage cyclone (6, 16) between attrition (2) and flotation (5), preferably after conditioning (4) for partial separation into cleaned material (7, 17) and an oil-enriched phase (14, 19). Flat-bed cyclones (6, 16) are to be used, in particular.
摘要:
L'invention se rapporte à un procédé pour enlever de matériaux granuleux, tels que des battitures et des minéraux contaminés par de l'huile, des substances grasses entraînées, notamment de l'huile, selon lequel les matériaux sont soumis, pour une purification en surface, à une sollicitation mécanique de corps solides (attrition 2), et à un conditionnement (4) avec addition de liquide ou, éventuellement lavés dans une installation de flottation (5) par un liquide de lavage contenant, le cas échéant, des réactifs tensioactifs et des dispersants. Conformément à l'invention, les matériaux sont traités entre l'attrition (2) et la flottation (5), de préférence après conditionnement (4), en vue d'obtenir une séparation partielle en un matériau purifié (7, 17) et en une phase enrichie en huile (14, 19), dans un cyclone à un ou plusieurs étages (6, 16). A cet effet, on utilise en particulier des cyclones à fonds plats (6, 16).
