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.

A method of fastening an edge structure to a construction element includes providing the construction element, being a planar structure with with two cover regions and a middle region between the cover regions; providing the edge structure being continuously extended, the edge structure having contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the construction element, and, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure; coupling energy into the edge structure and pressing the contact surfaces against the cover regions until at least a portion of the thermoplastic material is liquefied and pressed into the cover regions; and repeating or continuing the steps of coupling and pressing until the edge structure is attached to the building element at a plurality of discrete locations or over an extended region along an edge of the construction element.

A housing includes a first surrounding wall connected around a base wall. The first surrounding wall has a first joint portion opposite to the base wall, a first outer surface and a first inner surface. The first outer and inner surfaces extend from the first joint portion toward the base wall. The first joint portion is stepped and has a first projecting portion adjoining the first outer surface, and a first shoulder portion indented from the first projecting portion and proximal to the first inner surface. The first shoulder portion has a plurality of parallel spaced-apart ribs protruding therefrom in a same direction as the first projecting portion. Each of the ribs has a tip that does not extend beyond a top end of the first projecting portion.

The present technology discloses a system, for joining workpieces using energy, such as ultrasonic energy, where the energy concentrates at a location within a weld area, promoting sequential melting of a plurality of energy directors. The system can be configured so that the sequential melting begins at the center of the weld area and progresses outwards. Sequential melting may occur through use of a welding tip configured to reduce air pockets, a tapering the height of a plurality of energy directors, and/or tapering the energy directors themselves, all of which reduce the size of an energy transfer area produced by thermal energy. The present technology also includes a method for joining workpieces using energy such as ultrasonic energy that concentrates at a location within a weld area causing sequential melting of a plurality of energy directors using the aforementioned features.
摘要:
A method for connecting a surface-structured workpiece (SSW) and a plastic workpiece using a joining tool with a sonotrode. The method includes: positioning the SSW and the plastic workpiece on an anvil such that a structured contact surface section (SCSS) of the SSW faces a contact surface of the plastic workpiece; positioning the sonotrode in contact with an outer surface of the SSW that is opposite to the SCSS; and applying pressure to the sonotrode and/or the anvil perpendicular to the contact surface to hold the workpieces fixed between the anvil and the sonotrode and applying ultrasonic vibrations to the workpieces by the sonotrode for a predetermined period of time to induce softening of the plastic workpiece and penetrate pin-like elements of the SCSS into the plastic workpiece.

A method for watertight welding, and components formed using that welding method, wherein the welding method includes providing a first component half with a groove and a protruding ridge located therein, providing a second component half with a tenon shaped to match the profile of the groove, disposing the tenon inside the groove such that the tenon contacts the protruding ridge, applying an ultrasonic power source near the groove to melt the protruding ridge, and applying opposing vertical force to the first component half relative to the second component half, such that the protruding ridge wedges in a bonding seam between an outside surface of the tenon and an inside surface of the groove.
摘要:
An assembly including a joining element and an object, the object having a first outer layer, a second outer layer, and a middle layer between the first and second outer layers. The object has an opening that extends through the first outer layer and the middle layer, and the joining element is anchored in the opening. The joining element includes a proximal end, a distal end, a contact face in the area of the proximal end, a wall anchoring portion, and a tubular portion. The contact face is engaged by a vibrating tool that applies mechanical vibration and axial force to the joining element. The joining element includes a thermoplastic material at least at the circumferential surface of the wall anchoring portion and at the distal end to anchor the joining element to the first and second outer layers, respectively.

A method of anchoring a joining element to a hollow core board with the aid of mechanical vibration. The hollow core board has a first and second outer layers and a middle layer disposed between the outer layers. An opening, including a mouth, is provided in the hollow core board, the opening penetrating the first outer layer and the middle layer. The joining element includes a wall anchoring portion situated between a proximal end and a distal end thereof. A distal end of the wall anchoring portion is positioned into or onto the mouth with a sealing portion on a proximal end of the wall anchoring portion. The wall anchoring portion is forced through the mouth by applying mechanical vibration and a force parallel to the joining element axis, whereby thermoplastic material of the wall anchoring portion is liquefied and pressed into the first outer layer.
摘要:
A weldable component is described. The weldable component includes a weld rivet attached by a thin portion, which is designed to break during the ultrasonic welding process. The weld rivet is driven through a complementary void pocket which extends through the part and is positioned under the weld rivet. The weld rivet is embedded in the base component to form the weld. A welded joint and a method for ultrasonic welding using the weldable component are also described.
