| 摘要 |
The invention relates to a fracture-splitting method and a fracture-splitting apparatus (10) for fracture-splitting workpieces (90-490), in particular engine components (91) or connecting rods (92), having a cooling device (20-420) for cooling the workpiece (90-490) in a splitting zone (100), and having a fracturing device (11) for fracture-splitting the workpiece (90-490) in the region of the cooled splitting zone (100), wherein an inflow coolant duct (30-430) opens out at at least one outlet opening (31-431) of the cooling device (20-420) in order to cool the splitting zone (100), wherein the cooling device (20-420) has at least one sealing portion (24-424) for bearing in a sealing manner against the workpiece (90-490) next to the splitting zone (100) in order to cool the workpiece (90-490) in the splitting zone (100) in a locally delimited manner, and/or has at least one admission opening (41-441) of at least one outflow coolant duct (40-440), said admission opening (41-441) being arranged next to the at least one outlet opening (31-431) of the inflow coolant duct (30-430), in order to conduct the coolant (32) away from the splitting zone (100) of the workpiece (90-490). |
