FIELD: technological processes.
SUBSTANCE: invention relates to the field of metal forming, in particular to the production of components in the form of a hat. In the clamping step, the upper plate of this component is clamped using a punch and a clamp. After the clamping step, in the bending and stretching step, the matrix is bent and stretched by the vertical walls to the side opposite to the top plate on one side, in the lengthwise direction, of this component. In the bending step in the reverse direction, a holder is used to bend the vertical walls in the opposite direction, towards the upper plate, on the other, in the lengthwise direction, to the side of this component.
EFFECT: quality of the component in the form of a hat is improved by eliminating the cracking when its height changes.
