Embodiment Construction

[0023] figure 1 An extrusion head 12 is shown, of which a rotatable drive mandrel 13 is the central element. At the lower end of the extrusion head, the drive mandrel 13 extends to a drive mandrel head 14 having a smooth outer surface 15, which is generally frusto-conical, but may also be cylindrical. A 360 degree slot is machined into the circumference of the drive mandrel head to form part of the extrusion chamber 16 (described in more detail below). Depending on the location of the entry point 16a for the filler metal strip, the actual extrusion chamber may generally extend 180 degrees or more, more typically approximately 270 degrees, around the circumference of the surface 15 of the drive mandrel head 14, from which the extrusion chamber 16 begins. At entry point 16a and terminates at die orifice 19. Therefore, the shape of the extrusion chamber 16 is generally an arc rather than a full circle, such as image 3 better shown.

Abstract

A device for solid state joining of light metals like aluminium is described. The device utilizes the principle of continuous extrusion to add a string of filler metal into a groove separating the components to be joined, and shear deformation for surface oxide removal in the groove. The device comprises a rotating drive spindle (13) terminated in a drive spindle head (14). A groove with the shape of a circular arc constituting an extrusion chamber (16) is machined in the outer surface of the drive spindle head (14), the extrusion chamber (16) being limited radially outwards by a stationary annular metal shoe (17) surrounding the drive spindle head (14), the extrusion chamber (16) being terminated by an integrated (fixed) or replaceable abutment member (18) for diverting aluminium from its circular movement in the extrusion chamber (16) through a die orifice (19).

Description

technical field [0001] The invention relates to a device for joining lightweight metal components and alloys, especially aluminum components, including aluminum alloys and mixtures / composites containing lightweight metals, especially aluminium. The equipment uses the principle of continuous extrusion to add filler metal strips to slots separate from the components to be joined, and shear deformation to remove surface oxides in the slots. Background technique [0002] Usually, a technology for joining metal components emerges as an adaptive technology originally developed for the joining of ferrous metals. [0003] The connection of metals is largely connected by fusion welding, in which the base metal and suitable solder are melted by an arc, electron beam or laser beam, so that the metal-to-metal bonding is achieved at the trace part of the weld pool during the crystallization process . In fusion welding, only a portion of the applied energy causes welding, and thus bondi...
