Specific implementation mode
As shown in Fig. 2 to Fig. 5, a kind of metal plate Kong Zhe mechanisms of large area negative angle, including：
Lower die holder 1, top have die cavity 11, and side is equipped with lower mold forming public affairs 12 at least at the top of the die cavity 11,
The inner top side of the lower mold forming public affairs 12 has lead-in chamfered 121；
Lower die binder block 2 is slidably matched in die cavity 11 and in the vertical direction therewith, and top surface has for loading
The microscope carrier 21 of sheet metal component；
Elastic supporting member for supporting optical member 3, is set to the bottom of lower die holder 1, and lower die binder block 2 is lifted along die cavity 11 after popping up in top
