20130276287 | WIRE THREAD INSERT WITH REDRESSABLE MOUNTING TANG AS WELL AS ITS MANUFACTURING AND INSTALLATION - A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert. | 10-24-2013 |

20120260647 | HYDRAULICALLY OPERATED SETTING DEVICE WITH A HYDRAULIC AGGREGATE AND A JOINING METHOD FOR CONNECTING AT LEAST TWO COMPONENTS - A hydraulically operated setting device with a hydraulic aggregate as well as a joining method for connecting at least two components with the help of the hydraulically operated setting device is described. The cycle times compared to conventional joining methods are reduced through the targeted use of volume flows of hydraulic fluid in the prestroke chamber and the return-stroke chamber of the piston in connection with the plunger and the hold-down device chamber in connection with the plunge piston and the hold-down device. | 10-18-2012 |
20110290847 | HEAD PIECE FOR A SETTING DEVICE - The invention relates to a setting device for an auxiliary joining part, particularly a setting fastener or a punch rivet, including a driven punch which for a setting movement can be moved in a joining channel to which the auxiliary joining part can be loosely fed. The setting device includes a head piece in which a part of the joining channel runs, further including a plurality of compressed air ducts ending in the joining channel, and an exhaust air channel. The exhaust air channel ends adjacent to the front side of the punch moving the auxiliary joining part into the joining channel of the setting device such that an airflow can be generated in the joining channel in the direction of the front of the punch moving the auxiliary joining part by way of an overpressure which can be generated in the plurality of compressed air channels compared to the atmospheric pressure and by which the auxiliary joining part can be positioned on the front side of the punch. | 12-01-2011 |
