Abstract:
1. Impact machine for forming, cutting, or punching a working material in a mould die by impact action during an impact operation carried out by means of impact devices from two opposite directions, said impact devices being provided to strike the working material or impact members which transfer the impact energy of the impact devices to the working material, said die ( 9 ) being carried by a carrier ( 2 ) included in the impact machine, characterized in that said impact devices are provided to hit the working material or impact members which transfer the kinetic energy of the impact devices to the working material from two opposite directions essentially simultaneously, and that the die ( 9 ) is resiliently mounted in the carrier ( 2 ) and at least an inner resilient element ( 41 ), or set of resilient elements, is provided between an intermediate member and the die, that an outer resilient element ( 42 ), or set of resilient elements, is provided between the intermediate member and the carrier, and that one of said inner and outer resilient elements is provided to damp downwards directed forces acting on the die, while the other of said first and second resilient elements is provided to damp upwards directed forces acting on the die.
