[0012] Such as Figure 1 to Figure 3 As shown, a stamping die installation and positioning mechanism includes a press worktable 1 and a corresponding lower template of the stamping die; a set of cross-symmetrical centering keys 2 are provided on the press worktable 1; A set of key grooves matched with the set of centering keys 2 is provided on the lower template of the punching die. The set of centering keys 2 are four cross-symmetrical hexagons. In order to further ensure the positioning accuracy, both sides of the hexagons are symmetrically provided with inclined surfaces 21 that match the bottom of the keyway. The length of each hexagon is 300mm, the quenching hardness reaches HRC38-42, the surface roughness on both sides of the hexagon is Ra3.2, and the roughness of the inclined surface and other parts is Ra6.3. Two stepped bolt holes 2 are provided on each hexagon, and the centering key is fixed in the T-shaped groove on the working table of the press by two countersunk b...
