Problems solved by technology

The disadvantage of this arrangement is that the two vibrating heads only vibrate in phase with very wide adjustments, and another disadvantage is that the vibrating heads used have different vibration amplitudes
However, this requires a certain flexibility of the plastic part, which must accommodate these deviations in the final analysis, which in turn leads to poorer welding results

Embodiment Construction

[0050] FIG. 1 shows a known vibration head 2 , preferably, the vibration head 2 has a vibration unit 20 . The vibration unit 20 includes a pair of electromagnetic coils 22 arranged opposite to each other. At this time, it is also preferable to use a plurality of pairs of electromagnetic coils 22 arranged opposite to each other. When alternately charged, the plurality of coils 22 linearly vibrate the vibrator 24 disposed therebetween. In order to support the vibration of the vibrator 24 , it is fixed to a bridge 28 by a spring assembly 26 . The vibrator 24 is connected to the tool 30 . The tool 30 is used to receive the component in order to transmit the vibration of the vibrator 24 to the component. When a vibrating part is pressed against another part, the frictional heat generated by the vibration connects the two parts. Corresponding to the arrangement of the plurality of coils 22 , the vibrator 24 and thus the tool 30 also vibrate in the longitudinal direction of the v...

Abstract

The invention describes a vibration welding device with mechanically linked multiple vibrators. In this vibration welding device, a plurality of vibration units are arranged opposite to the elongated tool, so that the first direction of vibration of each vibration unit is oriented substantially transverse to the longitudinal axis of the tool, so that during vibration welding, both The individual parts may be welded to each other by vibration in a direction different from the longitudinal direction of the parts.

Description

technical field [0001] The invention relates to a vibration welding device with mechanically linked multiple vibrators. Furthermore, the present invention relates to the use of a vibration welding device for welding at least two elongate parts, a method for joining at least two elongate parts by means of said vibration welding device, and a vibration welding device in which a plurality of electromechanical vibrators are Mechanical connection) method of manufacture. Background technique [0002] Vibration welding is a known method in joining plastics. Two plastic parts are connected by means of friction and the heat generated thereby. Typically, one plastic part is held securely and the other plastic part is moved linearly or on rails relative to the other plastic part under pressure. [0003] In linear vibration welding, the relative motion of the plastic parts relative to each other is along the longer side of the geometry of the oscillating part. In order to prevent ti...
