FIELD: metal forming.
SUBSTANCE: inventions relate to metal forming and can be used in construction industry when making a cone on a pipe end pre-cut into sectors. Device for forming cone-shaped pile tip comprises housing in form of fixed cover, along axis of which there is a drive connected to diametrically located crimping jaws. On the drive a movable cover is installed, which is connected to the fixed cover by two groups of levers connected to each other. Crimping jaws are installed on ends of levers attached to fixed cover. At least two diametrically opposite crimping jaws are made as leading and elongated relative to auxiliary crimping jaws. Each of the leading jaws has an element for engagement with a mating element on the sector of the cut end of the workpiece.
EFFECT: possibility of using workpieces of different standard sizes and increased accuracy of the obtained tips.
