The utility model proposes floating precision blanking dies.
Referring to Figures 1 and 2, floating precision blanking die including work bench of punch press 1, is installed on work bench of punch press 1
Lower die 3, slider of punch 2 and the upper mold being installed on slider of punch 2 re-pack 4, and lower die 3 and upper mold re-pack between 4 from top to bottom
It is provided with upper mold 8, connecting plate 7, punch fixing plate 6 and cavity plate 5, upper mold 8, connecting plate 7, punch fixing plate 6 are fixedly connected on
Together, lower die guide sleeve 31 is set in lower die 3, is evenly arranged with eight lower die guide sleeves 31 in lower die 3, in corresponding lower die guide sleeve 31
Be provided with guide post 9 and guide post 9 and pass through cavity plate 5, punch fixing plate 6, connecting plate 7 and upper mold 8, guide post 9 pass through punch fixing plate 6,
At connecting plate 7 and upper mold 8 be equipped with upper die guide sleeve 10, guide post 9 divide for above lead shell, under lead shell and guide post core, guide post core leads shell in upper
It is inside equipped with the first spring, guide post core is led under is equipped with second spring in shell, above lead shell and be arranged in cavity plate 5, punch fixing plate 6, connect
In fishplate bar 7 and upper mold 8, and cavity plate 5, punch fixing plate 6, connecting plate 7 and 8 integral structure of upper mold are fixed, under lead shell position
In in lower die guide sleeve 31, when upper mold re-packs 4 without upper mold 8 is acted on, the first spring is in compressive state, and guide post 9 is additionally provided with
Second protrusion 92 of clamping cavity plate 5 keeps cavity plate 5 and lower die 3 to separate, and second spring is in compressive state, is provided with outside guide post 9
