Specific implementation mode
Structure of the combination of mould knife sharp angle degree and pad knife material for processing sheet metal, is shown in Fig. 1, Fig. 2：On mold 1
There are two the mold knife edge 2, the inner faces 3 of two mold knifes edge 2 to arrange that the outer end face 4 of two mold knifes edge 2 is outer in opposite directions for setting
Inclined-plane, pad knife installation cavity 5 is provided between the inner face 3 of two mold knifes edge 2, and pad knife 6 is filled in pad knife installation cavity 5, pads knife 6
Arcuate surface 7 be formed by parallel surface higher than the blade 8 of two mold knifes edge 2, the arcuate surface 7 of pad knife 6 is plane, pad knife 6
Material has resilient property, and the resilient property by padding knife 6 makes the arcuate surface 7 for padding knife and the upper surface of sheet metal contact begin
The shaping to sheet metal in die cutting process is completed in fitting eventually；
Two mold knifes edge 2 are arranged symmetrically about the width direction center vertical plane 9 of pad knife installation cavity 5, the mold knife edge 2
Convex top is blade 8, and the inner end inclined-plane 10 of blade 8 is from top to bottom towards in width direction center vertical plane 9 and width direction
The angulation σ gradients of heart vertical plane 9 are 5 °, and the outer end inclined-plane 11 of blade 8 is from top to bottom far from 9 and of width direction center vertical plane
