20090077786 | JOINING METHOD FOR OPERATING A FASTENING TOOL - In a method for joining at least two plate-shaped workpieces by a fastening tool and a device for operating the fastening tool, the fastening tool comprises a punch for exerting a punch force to perform a joining operation and a clamp for exerting a clamping force upon the workpieces at the joining area. During the joining operation the punch exerts a high punch force to perform the joining operation and the clamp exerts substantially no clamping force to allow for free material deformation in the joining area. After the joining operation both the punch and the clamp exert high forces at the same time to reduce any material deformations of the workpieces and to provide for compression of the workpieces in the joining area. Preferably the invention is used in a riveting tool for setting self-piercing rivets; as an alternative it may be used in a clinching tool. | 03-26-2009 |
20090317209 | Method For Mounting A Screw And A Thread-Armoring Element, And Arrangement For Carrying Out Said Method - A method for mounting a screw and a thread-armoring element in a receiving thread of a component is described, in which the thread-armoring element is immobilized on the screw and the screw with the thread-armoring element immobilized on it is then screwed into the receiving thread of the component in one single work step. An arrangement comprising a screw and a thread-armoring element immobilized on it for carrying out said method is also described. | 12-24-2009 |
20100163595 | Setting Device, Method and Apparatuses for Feeding Fastening Elements - The present invention discloses a feed apparatus, a feed channel and a setting device, that is used in connection with these specific apparatuses. The feed apparatus uses either a strip magazine | 07-01-2010 |
20100183404 | Method for Establishing a Nail Connection and a Nail for This Purpose - A method for establishing a nail connection between two components and a nail for this purpose are described. The nail | 07-22-2010 |
20110290848 | SETTING DEVICE HAVING A MAGAZINE AND A PROVISIONING MODULE FOR JOINING ELEMENTS - The present invention relates to a magazine of a setting device for storing and feeding a plurality of joining elements, particularly of joining elements, such as setting fasteners, to a provisioning module for joining elements and a setting device in combination with the joining elements. The magazine has a base element within the setting device including a storage groove, in which the joining elements can be received in an aligned and jointly moveable manner and one end of the base element ends in a head piece of the setting device. The magazine further includes an advancing mechanism, by which the joining elements can be moved within the storage groove towards the head piece of the setting device, as well as a dispensing mechanism, by which the joining elements can be fed individually from the storage groove to the head piece of the setting device. | 12-01-2011 |
20120260491 | SETTING DEVICE, SUPPLY MODULE FOR THE SETTING DEVICE, AND A JOINING METHOD FOR CONNECTING AT LEAST TWO COMPONENTS - The present invention discloses a setting device for connecting at least two components and comprises the following features: A first lever arm having a first working end, and a second lever arm having a second working end, that are pivotably connected to each other like pliers, a first linear drive connected to the first and the second lever arm so that, by changing of the length of the linear drive, the first and second working ends can move relative to each other, and a punch arranged at a first working end that is connected to a supply module for joining elements, and/or a hold-down module. | 10-18-2012 |
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 |
20120271581 | PROCESS MONITORING FOR HIGH-SPEED JOINING - A process monitoring method for a joining operation of a joining element at a speed of at least 5 m/s, in particular placing a bolt at least 10 m/s into at least one component with the aid of a placing device which has the following features: A plunger for placing the joining element, a buffer which limits a maximum deflection of the plunger in the joining direction, and a distance measurement with which the deflection of the plunger can be detected, wherein the process monitoring comprises the following steps: Detecting the travel of the plunger during the joining operation as a function of time in the form of a distance-time curve, detecting a placement of the plunger on the buffer, evaluating the distance-time curve such that, in the presence of at least one maximum followed by at least one minimum in the distance-time curve and without the plunger contacting the buffer, a joint connection is judged to be OK. | 10-25-2012 |
20130000101 | CONNECTION BETWEEN TWO COMPONENTS MADE OF REINFORCED PLASTIC AND METHOD FOR THE PRODUCTION THEREOF - The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element ( | 01-03-2013 |
