Striking unit and method for material processing by the use of high kinetic energy
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.
The invention relates to a method and an apparatus for material forming, by means of a movable impact head and tool combination (4) and a drive unit, in particular, t the method comprises moving the drive unit to provide kinetic energy to the impact head and tool combination (4), for the impact head and tool combination (4) to strike a work material (W), so as to form the work material (W), wherein a return movement of the movable impact head and tool combination (4), away from the work material, after the strike of the work material (W) by the impact head and tool combination (4), is dampened.
