Mechanical device for separating a workpiece part from a scrap skeleton in a workpiece cutting machining operation

A mechanical device for separating a workpiece part present as a machining product of a cutting machining operation of a plate-type workpiece, including a metal sheet, from a scrap skeleton present as a further machining product of the workpiece cutting machining operation from a product combination of the scrap skeleton and the workpiece part, the mechanical device comprising:

• a vibration generator, by which the product combination is configured to be excited to carry out combination vibrations which are carried out perpendicularly to a main plane of the product combination and which cause the workpiece part to be detached from the product combination,
• wherein the vibration generator comprises an excitation unit and a scrap skeleton support,
• wherein the scrap skeleton support is excitable by the excitation unit to carry out support vibrations perpendicularly to the main plane of the product combination;
• and
• a holder having a holding member, by which the product combination is configured to be supported on the scrap skeleton support effective perpendicular to the main plane of the product combination in order to carry out the combination vibrations with the scrap skeleton,
• wherein the holding member can be switched into a functional state and into a non-functional state and, in the functional state, applies force to the product combination on the scrap skeleton against the scrap skeleton support.
