Abstract: A method for material forming, by means of a movable impact head and tool combination and a drive unit includes moving the drive unit to provide kinetic energy to the impact head and tool combination, for the impact head and tool combination to strike a work material, so as to form the work material. A return movement of the movable impact head and tool combination, away from the work material, after the strike of the work material by the impact head and tool combination, is dampened.

Abstract: A method of processing a material by use of high kinetic energy comprises a piston driven from a start position by a hydraulic system pressure by a drive chamber, by only one stroke, to transfer high kinetic energy to a blank/tool to be processed, whereafter there is a risk that a rebound of the piston will occur, so a step is taken in connection with said stroke performed, to prevent said piston from making a rebound with an essential content of kinetic energy to avoid negative effects as a result, whereafter the piston is returned to said start position by means of a second chamber, wherein a valve means closes the driving connection between the system pressure and the piston, the valve means is controlled by a pilot valve controlling the entire striking progress, and the second chamber is pressurized with the system pressure during the entire striking progress.

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.

Abstract: 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.

Abstract: A method for material forming and/or cutting by means of a tool and a drive unit. The method includes moving the drive unit to provide kinetic energy to the tool, for the tool to strike a work material, so as to form and/or cut the work material when the tool is operatively disassociated from the drive unit before the tool strikes the work material.

Abstract: The present invention relates to a method at the material processing by the use of high kinetic energy, comprising a piston which is driven from a start position by a hydraulic system pressure (pS) by means of a drive chamber in order, by only one stroke, to transfer high kinetic energy to a blank/tool to be processed, whereafter there is a risk that a rebound of the piston will occur, and the method comprises that a step is taken in connection with said stroke performed, which step prevents said piston from making a rebound with an essential content of kinetic energy in order to avoid negative effects as a result of a rebound, whereafter the piston is returned to said start position by means of a second chamber, wherein said step comprises that a valve means closes the driving connection between the system pressure (pS) and the piston, wherein said step comprises that said valve means is controlled by a pilot valve controlling the entire striking progress, and that said second chamber is pressurized with the system pressure (pS) during the entire striking progress.
