20130185917 | BOLT ELEMENT AND A METHOD FOR THE ATTACHMENT OF A BOLT ELEMENT TO A COMPONENT OF A COMPOSITE MATERIAL - A method for the attachment of a bolt element to a component is described. The bolt element has a head part having a contact surface and a shaft part extending away from the head part, the shaft part having a tip provided at its end remote from the head part, the tip merging into a thread cylinder, optionally via a cylindrical region. The bolt element is pressed with the tip to the fore against the component and the tip is pressed through the component until the side of the component adjacent the head part of the bolt element enters to contact the thread cylinder and the tip thereby generates a hole in the component. The bolt element is subsequently turned so that the thread of the thread cylinder forms an internal thread in the wall of the hole. A bolt element is also claimed. | 07-25-2013 |
20130185921 | METHOD FOR THE ATTACHMENT OF A HOLLOW ELEMENT SUCH AS A HOLLOW RIVET OR A NUT ELEMENT TO A COMPONENT CONSISTING OF A COMPOSITE MATERIAL - A method for the attachment of a hollow element such as a hollow rivet or a nut element to a component consisting of a composite material, with the element having a flange part and a shaft part or rivet section extending away from the flange part, wherein a rivet section can also be formed at the free end of a shaft part. The hollow element has a central passage which is optionally provided with a thread cylinder. In the method an auxiliary tip is either passed from the flange side of the element remote from the shaft part and/or the rivet section through the passage or is introduced from the side of the free end of the shaft part and/or of the rivet section into the passage such that a conically converging region of the auxiliary tip projects from the free end of the shaft part or of the rivet section. The hollow element is pressed with the tip to the fore against the component and the tip is pressed through the component until the component comes into engagement with the side of the flange part adjacent to it and the tip has produced a hole in the component. | 07-25-2013 |
20130189054 | COMBINATION OF FUNCTIONAL ELEMENT AND PRESSURE PLATE - The invention relates to a combination of a functional element having a flange section and a connection section, in particular a rivet element, and a pressure plate, in particular a pressure plate having an opening, for attachment to a component, in particular to a panel of composite material or sheet metal, wherein the functional element and the pressure plate are formed to be arranged on opposite sides of a hole of the component and are to be connected together via the connection section which extends through the hole, in particular by riveting, in order to clamp a region of the component surrounding the hole between the flange section and the pressure plate and wherein the pressure side of the pressure plate confronting the component in the attached state is provided with a means providing security against rotation. | 07-25-2013 |
20130207298 | METHOD FOR THE MANUFACTURE OF A HOLE IN A COMPONENT CONSISTING OF A COMPOSITE MATERIAL - A method for the manufacture of a hole in a component consisting of a composite material, such as a fiber reinforced plastic part or a fabric reinforced plastic part, which is characterized in that the component having first and second oppositely disposed sides is placed with its first side on a support having an iris diaphragm, in that a tip which diverges in the axial direction is pressed coming from the second side of the component through the component, which optionally has a pre-piercing, for the formation of the hole or for the enlargement of the pre-piercing and in that the iris diaphragm has a smaller starting opening which receives a narrower region of the tip and opens into a larger opening with increasing penetration of the component by the tip, whereby the component is supported during the hole formation over an as large as possible area from the first side. A piercing aid in the form of an iris diaphragm or a corresponding die button is likewise claimed. | 08-15-2013 |
20140241831 | HOLLOW ELEMENT FOR ATTACHMENT TO A COMPONENT COMPRISING A COMPOSITE MATERIAL - A hollow element such as a hollow rivet or a nut element for attachment to a component consisting of a composite material such as a fiber reinforced plastic part or a fabric rein-forced plastic part is presented. The element has a flange part and a shaft part extending away from the flange part and/or a rivet section, wherein the rivet section, is present, can also be formed at the free end of the shaft part, with the a hollow element furthermore having a central passage, which is optionally provided with a thread cylinder. The hollow element is used in combination with an auxiliary tip which is either inserted from the flange side of the element through the passage, or from the side of the free end of the shaft part of the rivet section into the passage, such that a conically converging region of the auxiliary tip projects from the free end of the shaft part or of the rivet section. | 08-28-2014 |
20150059153 | PUNCH RIVET AND METHOD FOR THE ATTACHMENT OF INDIVIDUAL COMPONENTS TO ONE ANOTHER OF WHICH AT LEAST ONE COMPONENT IS FORMED BY A WORKPIECE OF COMPOSITE MATERIAL - A punch rivet for fastening individual components to one another of which at least one component is formed by a workpiece of composite material, with the punch rivet having a flange of larger diameter, a rivet section of smaller diameter and a ring-like component contact surface at the side of the flange adjacent the rivet section and surrounding the rivet section, with the rivet section having at its free end a ring surface for the piercing of the two workpieces which stands at least substantially perpendicular to the central longitudinal axis of the punch rivet and an inner concave ring surface which forms the transition from the end of the punch rivet into the hollow internal space of the rivet section. Ribs extending parallel to the longitudinal axis are provided at the generally cylindrical outer surface of the rivet section and preferably extend up to the free end face of the rivet section. In addition, a method is claimed. | 03-05-2015 |
20150059156 | METHOD FOR THE ATTACHMENT OF A FASTENER ELEMENT TO A WORKPIECE, A COMBINATION OF A WASHER WITH A DIE BUTTON AND ALSO A DIE BUTTON - A method for the attachment of the fastener element to a workpiece with the aid of a washer and also a die button are described. The fastener element has a flange of larger diameter, a rivet section of smaller diameter which extends away from the flange and a workpiece contact surface at the side of the flange adjacent the rivet section. The die button is provided to receive a washer and has a central post the end face of which lies at least substantially flush with the side of the washer adjacent to the workpiece. The non-pre-pierced workpiece is pierced by the said end face of the central post and the free end of the rivet section and the rivet section of the fastener element is subsequently deformed to form a rivet bead. Moreover, a die button and a combination of a die button with a washer are claimed. | 03-05-2015 |
20150074973 | HOLE PUNCH AND ALSO A METHOD FOR THE PIERCING OF A WORKPIECE WHICH IS PRESENT AS A FOAM MATERIAL AND/OR AS A SANDWICH MATERIAL AND ALSO A METHOD FOR THE MANUFACTURE OF THE HOLE PUNCH - A hole punch and a method for piercing a workpiece wherein a hole punch includes a sheet metal part and a piercing body attached thereto which carries out the piercing function and which is provided with a thread cylinder or can be provided with a thread cylinder, for example by pressing a threaded pin into a centrally arranged passage of the hole punch, wherein the hole punch can also be formed in one piece as a piercing body with a sheet metal-like flange. Furthermore a method is claimed for the manufacture of the hole punch. | 03-19-2015 |
20150082607 | PUNCH RIVET AND ALSO A METHOD AND APPARATUSES FOR ATTACHMENT OF INDIVIDUAL COMPONENTS TO ONE ANOTHER OF WHICH AT LEAST ONE COMPONENT IS FORMED BY A WORKPIECE OF COMPOSITE MATERIAL - A hollow punch rivet is described having a flange and a rivet section. Furthermore, a method for the attachment of individual components to one another using a punch rivet is described, with at least one of the components being formed by a material of the composite material. The method includes the following steps:
