The invention belongs to the technical field of
aircraft manufacturing, and discloses a separated double-sided energy conducting rib and a preparation method of the energy conducting rib, the separated double-sided energy conducting rib comprises a base plate and energy gathering structures, the two sides of the base plate in the first direction are each provided with a plurality of energy gathering structures distributed at intervals, each energy gathering structure is a
pyramid boss, the edge apex angle of each
pyramid boss is alpha, and the edge apex angle of each
pyramid boss is alpha; and alpha is not less than 60 degrees and not more than 120 degrees. According to the
ultrasonic welding device, the energy gathering structures are arranged on the two sides of the base plate, so that during
ultrasonic welding operation, the surfaces of
welding workpieces on the upper side and the lower side can be started at the same time, the uniformity of a
welding area is improved, the strength of a
welding interface is improved, and the energy gathering structures are pyramid bosses, so that the focusing effect is enhanced; by limiting the edge apex
angle alpha, on one hand, excessive focusing and too fast temperature rise caused by too small edge apex angle are avoided, and on the other hand, unobvious focusing effect, slow melting speed, prolonged welding time and reduced welding efficiency caused by too large edge apex angle are avoided.
