FIELD: mechanics.
SUBSTANCE: invention is referred to methods of hard-alloy teeth pressing into cone body intended for crashing rocks. A lubricant is introduced into contact area of items to be joined. i.e. teeth and cone body. After that the assembling force is applied to the joined items and elastic vibrations are simultaneously induced in them. The axial relative position of joined items is continuously measured and when the preset value is achieved, the position is fixed by the force avoiding reverse axial relative shifting of the joined items. After that the amplitude of elastic vibrations is increased and vibration quality is controlled by dynamic factor to define completion of pressing cycle.
EFFECT: reduced pressing force and increased strength of joining.
