Abstract
A method for material forming uses a movable tool and a drive unit the method including 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 the method including providing an impact head between the drive unit and the movable tool, and providing the kinetic energy to the tool by the drive unit striking the impact head, the impact head (extending in the direction of the stroke from an impact end to a base region, where the base region is closer to the tool than the impact end. The method includes arranging the impact head so that the impact end has laterally, in relation to the direction of the stroke, a smaller extension than the base region.

A method for material forming, by means of a movable 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,
- providing an impact head between the drive unit and the movable tool,
- providing the kinetic energy to the tool by the drive unit striking the impact head, the impact head extending in the direction of a stroke from an impact end to a base region, where in the base region is closer to the tool than the impact end,
- arranging the impact head so that the impact end has laterally, in relation to the direction of the stroke, a smaller extension than the base region, and
- providing the impact head and the tool with a respective collar at an interface between the impact head and the tool, the collar of the tool surrounding, as seen in the direction of the stroke, a working surface of the tool which comes into contact with the work material during the stroke,
- wherein a first portion of the impact head extends from the collar of the impact head, to the impact end of the impact head, wherein the first portion presents a perimeter edge at the collar of the impact head, which, as seen in the direction of the stroke, substantially coincides with the working surface.
An apparatus for material forming, comprising:
- a tool and a drive unit, the drive unit configured to provide kinetic energy to the tool for the tool to strike a work material, so as to form the work material,
- an impact head located between the drive unit and the movable tool, and
- the apparatus being arranged to provide the kinetic energy to the tool by the drive unit striking the impact head the impact head extending in the direction of the stroke from an impact end to a base region, wherein the base region is closer to the tool than the impact end,
- wherein the impact head is arranged so that the impact end has laterally, in relation to the direction of the stroke, a smaller extension than the base region,
- wherein the impact head and the tool comprises a respective collar at an interface between the impact head and the tool, the collar of the tool surrounding, as seen in the direction of the stroke, a working surface of the tool which is arranged to come into contact with the work material during the stroke, and
- wherein a first portion of the impact head extends from the collar of the impact head, to the impact end of the impact head, wherein the first portion presents a perimeter edge at the collar of the impact head, which, as seen in the direction of the stroke, substantially coincides with the working surface.
