Summary: | The invention discloses a combined clamp for cutting edges of aero-engine blade forgings and an edge cutting method. When an optical fiber laser cutting machine is adopted for edge cutting, the combined clamp is composed of an edge cutting dragging block, a silica gel gasket and an inner hexagon screw, and when an electric spark wire cutting machine is adopted for edge cutting, the edge cutting dragging block and the silica gel gasket are combined. The combined clamp is composed of a trimming dragging block, a conductive positioning block and a fastening screw. The positioning cavity of the trimming dragging block is enlarged by a certain gap on the basis of a finish forging mold cavity without considering the shrinkage rate, and follows a 6-point positioning rule when a blade forge piece is designed, so that accurate clamping positioning of the blade can be realized, the profile of the cutting dragging block is reduced by a certain offset gap on the basis of the trimming profile of the blade forge piece, and |
