| 20080276683 | PRESSING DEVICE - Disclosed is a pressing device for compressingly joining pipe-shaped workpieces, particularly a pipe end and a fitting mounted thereon. At least one of the workpieces is plastically deformed by several press members which are movable along a central longitudinal axis of the workpieces for performing the compression. In order to produce a pressing device with several compression jaws that are comparatively easy to mount and allow the press members to be engaged as centrally as possible during compression, at least two press members are pivotally connected to each other by means of two articulated levers embodied as angle levers for applying compression force. The angle levers pressingly lean on a (first) press member, and both angle levers are train-connected to the same (second) press member. | 11-13-2008 |
| 20090133591 | METHOD OF OPERATING A HYDRAULIC PRESSING UNIT, AND HYDRAULIC PRESSING UNIT HAVING A HYDRAULIC PUMP - The invention relates firstly to a method of operating a hydraulic pressing unit ( | 05-28-2009 |
| 20090162135 | CABLE LUG COMPRISING A NUT OR FUNCTIONAL PART, METHOD FOR THE PRODUCTION OF SUCH A CABLE LUG, AND NUT - A cable lug and a method of use is provided. The cable lug has a receiving tube section for a cable, a flat piece-connecting section that is molded on and is provided with a bore, and a nut which is captively and preferably rotatably mounted on the flat piece-connecting section. The nut does not penetrate the flat piece-connecting section while being mounted by a shaped mounting material section of the flat piece-connecting section, which extends into an undercut in the nut. The mounting material section is in the undercut with an axial clearance. The mounting material section is rooted in a lowered in a step-type manner in the flat piece-connecting section. The lowered area is rotationally symmetrical and is provided with a conical section which opens outward and vertically and encompasses at least one conical area. | 06-25-2009 |
| 20100229368 | METHOD FOR THE PRESSING OF A PRESS FITTING, AND PRESSING TOOL FOR THIS PURPOSE - The invention firstly relates to a method for the pressing of a press fitting ( | 09-16-2010 |
| 20100275672 | HYDRAULICALLY DRIVEN PRESSING DEVICE, AND METHOD OF PRESSING A FITTING - The invention relates to a hydraulically driven pressing device ( | 11-04-2010 |
| 20100300308 | METHOD FOR THE OPERATION OF A MOTOR-DRIVEN HAND-HELD PRESSING APPARATUS, AND HAND-HELD PRESSING APPARATUS - The invention relates to a method for operating a motor-driven hand-held pressing apparatus. In said method, once a switch has been actuated, one or more pressing jaws is/are moved from a starting position into a closed pressing position until a predefined pressing force has been reached or a given amount of time has lapsed, whereupon the pressing jaw/s is/are automatically released, e.g. using the return travel of a plunger. The releasing action can be interrupted in an intermediate position, before reaching the starting position, so as to start a subsequent pressing process from such an intermediate position. In order to be able to reach the advantage of the intermediate position without having to intervene when similar processes are carried out, a measure of the travel and/or the time and/or the pressure determined during the pressing process and associated with the intermediate position is detected or stored in order to be able to automatically interrupt the releasing action in the respective intermediate position on the basis of said measure during subsequent pressing processes. | 12-02-2010 |
| 20110113851 | PAIR OF PRESSING JAWS FOR HYDRAULIC OR ELECTRIC PRESSING TOOL - The invention relates to a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, two pressing jaws connected to one another in an articulated manner forming a pair of pressing jaws, the pressing jaws being biased into their open position by a tension spring which spans a free space between the two pressing jaws, and in each case one end of the tension spring being accommodated in an accommodating opening which opens out into a narrow peripheral side of the pressing jaw, this narrow peripheral side being directed toward the free space, and, in order to secure the tension spring, a tension-spring end engaging around a pin-like securing part, which securing part is disposed at that end of the accommodating opening which is directed away from the free space. In order to secure the tension spring in a functionally advantageous manner, it is provided that the securing part is formed as an integral crosspiece of the pressing jaw. | 05-19-2011 |
| 20110247506 | HAND-HELD PRESSING APPARATUS - A hydraulic pressing unit includes a hydraulic pump, supply and hydraulic chambers, moving and stationary parts, a restoring spring, and a return valve provided within or attached to a housing. The moving part is displaced from a starting position into a pressing position as a result of filling the hydraulic chamber with a hydraulic medium from the supply chamber by using the hydraulic pump. The return valve is automatically displaced into an open position as a result of a hydraulic pressure corresponding to the pressing position, and the restoring spring moves the moving part. A piston acts on the flow of the hydraulic medium and lowers the pressure such that the return valve is displaced into the closed position. | 10-13-2011 |
| 20120073112 | HYDRAULICALLY DRIVEN PRESSING DEVICE AND METHOD OF PRESSING A FITTING - A method of using a hydraulically driven pressing device for pressing a fitting on a tube is provided. The pressing device includes a piston and a cylinder for acting on pressing jaws. A piston shaft is connected to rollers. The pressing device can be used to carry out pressing operations requiring different levels of pressing power, by using an adjustable stop which is provided in the direction of displacement of the piston in order to achieve different end positions for the piston during the piston return stroke. | 03-29-2012 |
