Publication number: 20220371423Abstract: A motor vehicle shell of a motor vehicle includes a frame structure that is formed by crossmembers and by longitudinal members. The frame structure is closed peripherally and protrudes downwardly in a vertical direction of the motor vehicle from a base element. A receiving chamber for receiving an electrical energy store is delimited by the frame structure. A cover is formed separately from the frame structure and is disposed opposite the base element. The receiving chamber is closed downwardly in the vertical direction of the motor vehicle by the cover. An annular and dimensionally stable intermediary element is formed separately from the frame structure and separately from the cover. The intermediary element is disposed between the frame structure and the cover and the intermediary element is fixed at least in a liquid-tight manner on the frame structure by a firmly bonded connection.Type: ApplicationFiled: September 24, 2020Publication date: November 24, 2022Inventors: Clemens BALKE, Jan DRECHSEL, Leif ECKLE, Patrick HEBER, Hans HOFELE, Frank IMRECKE, Stefan LUTZ, Andreas MAIER, Franz MAIER, Jan-Mark OPELKA, Markus ORNER, Calixte ROLLAND, Thomas WEBER

Patent number: 10160023Abstract: The drawing press according to the invention includes a support structure for supporting a metal sheet holder which is part of a tool and supported on the press frame via the support structure. The metal sheet holder is assigned a plunger with a die tool, whereas the plunger is moved by means of a plunger drive which includes a blocking position. The blocking position is obtained, for example, by a drive which, in the blocking position does not transmit any movement of the drive output to the driving servomotor. This can be achieved, for example, by an eccentric drive in the stretched position thereof. For performing the actual drawing stroke, the stamping tool is vertically movably supported. A carriage is raised or lowered by the press table by means of a table drive. As table drive, preferably a servomotor with a non-linear drive, such as an eccentric drive is used.Type: GrantFiled: February 13, 2013Date of Patent: December 25, 2018Assignee: SCHULER PRESSEN GMBHInventors: Dietmar Schoellhammer, Martin Schmeink, Andreas Dangelmayr, Hans Hofele, Juergen Fahrenbach

Patent number: 7752881Abstract: Press driving modules are provided to permit a standardized press design. The presses of a press line are equipped with always identical press driving modules, and the pressing force of the presses is varied only by the adaptation of the number of press driving modules. The press driving modules each contain two driving devices, respectively, that interact parallel or in series and have different characteristic curves. In particular, they have different maximal traveling speeds and different maximal forces. They can also have a different design with respect to their positioning capability and path resolution. This concept permits not only a standardization of presses of different performance classes within a press line but, beyond that, the largely free definition of characteristic path-time curves of the slides, and thereby finally also a freer design of workpieces, particularly of vehicle body parts.Type: GrantFiled: August 2, 2006Date of Patent: July 13, 2010Assignee: Schuler Pressen GmbH & Co.

Patent number: 7287950Abstract: In a transfer arrangement and method for transferring a workpiece between first and second spaced locations along a guide rail with a carriage movably supported on the guide rail, a transfer arm is pivotally supported on the carriage and carries at its free end a workpiece holder which is accelerated by the carriage with the arm essentially stretched out in the movement direction out of, and decelerated into, the end positions, and, in an intermediate position, the carriage movement is slowed down or even reversed while the workpiece holder is moved along by a pivot movement of the arm.Type: GrantFiled: April 7, 2005Date of Patent: October 30, 2007Assignee: Schuler Pressen GmbH & Co.

Patent number: 7159438Abstract: A transfer press provided with a transfer device, having transfer units provided with cross members (37) for which the length is shorter than the width of a tool. The transfer units (29 to 32) are arranged completely between the processing stations or stages, are mounted on the crown or head piece, and are not provided with elements extending beside the tools or between supports of adjacent processing or press stations. Thus, the full width spanned by the press supports can be used for the tools. In addition, tools can be used which are provided with guides, effective between the upper tool and the lower tool, particularly in the side region. The work pieces are handled solely by means of the openings, freed by the tools and pointing counter to the transporting device, wherein no element of the transfer device extends past the side limits of the tool.Type: GrantFiled: June 25, 2004Date of Patent: January 9, 2007Assignee: Schuler Pressen GmbH & Co.
