The invention relates to an apparatus for material forming, by means of a tool (41) and a drive unit (2), the apparatus being arranged to move the drive unit (2) to provide kinetic energy to the tool (41), for the tool (41) to strike a work material (W), so as to form the work material (W), the apparatus being provided with an impact head (4″) between the drive unit (2) and the tool (41), and the apparatus being arranged to provide the kinetic energy to the tool by the drive unit (2) striking the impact head (4″), wherein at least a region of the impact head (4″) is allowed to move in relation to the tool (41) laterally to a direction of the stroke of the drive unit, whereby the impact head is arranged to expand laterally in relation to the tool. The invention also relates to a method for material forming.
An apparatus for material forming, by means of a tool (4′) and a drive unit, the apparatus being arranged to move the drive unit to provide kinetic energy to the tool, for the tool to strike a work material, so as to form the work material, the apparatus comprising an impact head between the drive unit and the tool, and the apparatus configured to provide the kinetic energy to the tool by the drive unit striking the impact head, wherein at least a peripheral region of the impact head is configured to move in relation to the tool laterally to a direction of the stroke of the drive unit, wherein the entire impact head is arranged to expand laterally in relation to the tool.
A method for material forming, by means of a tool and a drive unit, the method comprising moving the drive unit to provide kinetic energy to the tool, for the tool to strike a work material, so as to form the work material, wherein the kinetic energy is provided to the tool by the drive unit striking an impact head between the drive unit and the tool, wherein upon the strike of the impact head by the drive unit, at least a peripheral region of the impact head is configured to move in relation to the tool laterally to a direction of the stroke of the drive unit, whereby the entire impact head is allowed to expand laterally in relation to the tool.
