Device for setting a setting element in a component

The invention relates to a device for setting a setting element having a first plastic material in a component having a second plastic material, comprising a rotational advancing unit, by means of which the setting element can be rotated about an axis of rotation and simultaneously an axial force acting in the direction of the axis of rotation can be applied to the setting element in order to drive the setting element into the component, a friction welding joint thereby being produced between the setting element and the component, a differential-distance measuring apparatus for measuring the differential distance between a surface of the component and a surface of the driven setting element, and a control unit for controlling the rotational advancing unit in dependence on the measured differential distance.

Anchoring a joining element in an object

A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.

METHOD FOR WELDING MOLDED BODIES
20190291356 · 2019-09-26 ·

A process for welding a first molding to a second molding. The process uses an implement including first and second external surfaces. Each external surface further includes a duct. An end of the first molding is heated by a hot gas while the end is at a distance from the duct-entry plane in the range from 3 mm outside the duct to 10 mm inside the duct. A junction area of the second molding is heated by a hot gas while the junction area is at a distance from the duct-entry plane in a range from 3 mm outside the duct to 10 mm inside the duct. The heated end and the heated junction area are then brought into contact with one another and cooled, forming a weld between the first molding and the second molding. Also disclosed is a welded molding obtainable by the process of the invention.

Method of anchoring a first object in a second object

A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.
