Patent number: 11020818Abstract: A connection element for an interlocking connection to at least one component includes at least one component held between the connection element and a securing element wherein the connection element and the securing element enter into a friction welded connection, having a head with a drive and a shaft having at least two cutting structures on a front side. The at least two cutting structures have cutting edges situated in a cutting plane, wherein the cutting plane borders the shaft, and the at least two cutting structures are also spaced apart in the circumferential direction and define a cutting diameter. A cross-section of the shaft has a reduced extension between the cutting structures relative to the cutting diameter, wherein the area of the reduced extension extends in the axial direction at least with the length of the cutting diameter from the cutting structures in the direction of the head.Type: GrantFiled: April 15, 2016Date of Patent: June 1, 2021Assignee: EJOT GmbH & Co.

Patent number: 10160068Abstract: A method for supplying, positioning and processing fixing elements using a transport means which moves the fixing elements from a starting position to a processing position whereby the individual fixing elements are introduced into a chuck provided with two clamping jaws, are held by the clamping jaws in an engaging position and, once the chuck has been positioned, are taken up from this position by a driving element and the chuck presses them against a locating device and a connection is made to a component part by the driving element when the chuck is opened, wherein the upward motion of the chuck, while feeding the fixing element to the locating device, prevents the supply of further fixing elements to the chuck.Type: GrantFiled: September 13, 2016Date of Patent: December 25, 2018Assignee: EJOT GMBH & CO. KGInventors: Mario Maiwald, Jörg Thiem, Gerhard Dubiel, Marco Mielisch, Sebastian Zebisch, Marco Werkmeister, Nico Oschmann

Patent number: 8752603Abstract: Apparatus for connecting at least two plates (1, 2) of which a supporting plate (1) comprises a higher strength than a supported plate (2) posed thereon. By means of a connecting element (5) rotated by a rotational feeder unit (11), the connecting element with a collar (6) presses the supported plate (2) onto the supporting plate (1). With a shaft (10) a friction welding connection to the supporting plate (1) is made. The rotational feeder unit (11) is provided with a measurement device with measures an axial force exerted by the rotational feeder unit as well as a respective feeding motion and which indicates, upon abutment of the shaft of the connecting element onto the supporting plate, the pressure increase encountered therein, which, thereby, advances the rotational feeder unit, the feeding motion of which is adjustable to at least three sequential connecting stages.Type: GrantFiled: August 12, 2010Date of Patent: June 17, 2014Assignee: EJOT GmbH & Co. KGInventors: Eberhard Christ, Jörg Thiem, Marco Werkmeister

Publication number: 20130264783Abstract: The invention relates to a device for supplying and positioning fixing elements (8), comprising a chuck (18) that is provided with two spring-loaded stopper parts (1, 2) and that holds one fixing element (8) respectively for further processing. The invention is characterised in that the stopper parts are design as clamping jaws (1, 2) with which an actuation element (3) is associated that reaches between these jaws and that is provided with a narrow section (6) and two neighbouring extensions (4, 5) in an axial direction. Said actuation element is connected to an axial slide (21) for axially moving said actuation element (3), and is used to open and close the chuck (18) by forcing the clamping jaws (1, 2) apart, releasing the fixing element (8) for processing when the chuck (18) is opened.Type: ApplicationFiled: October 25, 2011Publication date: October 10, 2013Applicant: EJOT GMBH & CO.

Patent number: 8486508Abstract: The invention relates to a method for producing a friction-welded connection between a plurality of superimposed flat components held together by a connecting member, wherein a collar of said connecting member rests on an upper component and the front end of said connecting member forms a friction-welding zone with a lower component, said friction-welding zone being produced by rotation and pressure of the connecting member. After formation of the friction-welding zone, the rotation of the connecting member ceases at the end of a first step and, in a second step, upon cessation of the rotation of the connecting member prior to contact of the collar with the upper component, a pressure is exerted on the connecting member by a pressure-applying tool, said pressure pressing the collar against the upper component because of a deformation.Type: GrantFiled: September 14, 2007Date of Patent: July 16, 2013Assignee: Ejot GmbH & Co.

Patent number: 8434962Abstract: The invention relates to a friction welding joint of a plurality of two-dimensional components positioned on top of each other, which are held together by means of a connecting body, which rests on an upper component by means of a collar. The connecting body is configured as a pipe piece, and the upper component is penetrated by the connecting body having a front annular cutting edge by means of rotation and pressure, wherein the connecting body, after cutting through the upper component with the front thereof and receiving the cut-out material of the upper component in the hollow space thereof, together with the lower component forms a friction welding zone created by means of rotation and pressure of the connecting body.Type: GrantFiled: October 29, 2007Date of Patent: May 7, 2013Assignee: EJOT GmbH & Co. KGInventors: Eberhard Christ, Jorg Thiem, Torsten Fuchs, Gerhard Dubiel

Publication number: 20090317179Abstract: The invention relates to a friction welding joint of a plurality of two-dimensional components positioned on top of each other, which are held together by a connecting body which rests on the upper component by means of a collar and which, after penetrating the upper component by means of its end face as a friction welding surface, forms a friction welding zone on the lower component by means of the rotation and pressure of the connecting body. This combination includes the following features: a) An existing corrosion protection layer or corrosion layer is removed from the friction welding surface of the connecting body made of steel; b) The lower component is made of steel; c) the upper component is made of a material that is softer than that of the lower component.Type: ApplicationFiled: June 16, 2009Publication date: December 24, 2009Applicant: EJOT GmbH & Co.
