Abstract
In a device for breaking out a workpiece (3) from a material sheet (2) through an opening (4) of a die (1) by means of a breakout tool (5), the die (1) is to have a plug-in unit (22), wherein a breakout module (9.1-9.4) is insertable into the plug-in unit (22), wherein the breakout module (9.1-9.4) is composed of an insert (10) and of a module lobe (11), wherein the insert (10) has a surface (16) and a shearing edge (17), wherein the shearing edge (17) toward a bearing face (12) of the module lobe (11) configures an offcut length (18), and wherein the offcut length has a height (h) of 0.8 mm to 1.8 mm, and preferably of 1.5 mm.

Device for breaking out a workpiece (3) from a material sheet (2) through an opening (4) of a die (1) by means of a breakout tool (5), wherein the die (1) has a plug-in unit (22), wherein a breakout module (9.1-9.4) is insertable into the plug-in unit (22),
- wherein the breakout module (9.1-9.4) is composed of an insert (10) and of a module lobe (11) having a bearing face (12) for receiving the workpiece (3) after breaking out,
- wherein the insert (10) has a surface (16) and a shearing edge (17),
- wherein the shearing edge (17) faces toward the bearing face (12) and an offcut surface extending from the shearing edge (17) to the bearing face (12) and defining an offcut length (18), and
- wherein the offcut length has a height (h) from the surface (16) to the bearing face (12) of 0.8 mm to 1.8 mm, and
- wherein the module lobe (11) is at least partially resilient.
