摘要:
A lightweight component is equipped with two cover layers, which are made of a wood material, and a filling disposed in between the layers after cutting everything to size, having an edge support including thermoplastic material. The edge support is anchored in both the first and second cover layers starting from the narrow side. Anchoring is achieved by bringing the edge support into contact with the respective cover layer and coupling mechanical vibrations into the edge support by a sonotrode engaging from the narrow side. The edge support at the same time is pressed against the cover layer such that, in the region of a transition between the thermoplastic material and the wood material of the cover layer, part of the thermoplastic material is liquefied and pushed into the cover layer material, thereby producing a positively engaged anchoring after hardening.

A method of manufacturing a product includes the steps of providing a first and a second product part, each including a structure of fibers; arranging the first and second product parts relative to one another and against a support; providing a connecting element having a thermoplastic material; pressing the connecting element against the product parts to compress the semi-parts between the connecting element and the support and impinging the connecting element with energy, thereby causing thermoplastic material of the connecting element to become flowable, and causing the connecting element to be pressed into the product parts; and causing the thermoplastic material to re-solidify, thereby connecting the first and second product parts with each other.

A device for the anchoring of a suture in tissue includes a guide sleeve, a sonotrode, an anchor and the suture. The guide sleeve has a distal part with a smaller cross section and a proximal part with a larger cross section. The sonotrode extends through the lumen of the guide sleeve and has a distal end and a proximal end, the proximal end being designed for coupling the sonotrode to a vibration source (e.g. an ultrasonic device). The anchor is arranged at the distal end of the device and includes an anchor foot and an anchoring sleeve sitting on a shoulder of the anchor foot. The anchoring sleeve consists of a material which is liquefiable through mechanical vibrations. A middle portion of the suture runs through the anchor foot and two end portions of the suture are attached to the guide sleeve.

A joining element to be anchored in an object with the aid of a thermoplastic material and mechanical vibration includes a proximal end and a distal end that are spaced from one another along an axis of the joining element. A contact face is in the area of the proximal end, the contact face being suitable for being contacted with a vibrating tool for applying, to the joining element, mechanical vibration and a force parallel to the axis. The wall anchoring portion is situated between the proximal end and the distal end, and has a circumferential surface being equipped with a plurality of recesses and radially protruding energy concentrating elements between the recesses. A tubular portion is situated between the proximal end and the distal end and extends distally from the wall anchoring portion.
摘要:
A method of manufacturing and assembling a first and a second object wherein the first object is made by bringing a flowable compound into a first object shape and then subjecting the flowable compound to a hardening process that results in a change of a chemical composition of the flowable compound, thereby creating the first object or a part thereof. Then, the first object is positioned relative to a second object, and a flow portion of the hardened article of the modified compound is caused to become flowable by an input of energy. An interpenetration zone of the flow portion and structures of the second object is created, and the flow portion is allowed to re-solidify, whereby the interpenetration zone between the re-solidified flow portion and the structures of the second object secures the first and second objects to each other.

A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.

摘要:
A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.
摘要:
A method and installation for joining a cover layer to an object in a continuous process. Joining is effected with the aid of a joining material having thermoplastic properties, wherein the joining material is arranged between the cover layer and the object and is liquefied using ultrasonic vibration energy. Before application of the ultrasonic vibration energy, the joining material is preheated in a contactless manner with the aid of electromagnetic induction in the region of the glass transition temperature of the joining material or above this glass transition temperature. The object is in particular a chip board and the cover layer an edge strip to be joined to an edge of the chip board.
