The utility model provides a stamping die of band elimination material muscle utilizes the cooperation of holding down the material muscle on taking off the material flange on the flitch and the lower backstop board, pushes down stamping material's edge part earlier before the shaping power increase for holding down the clout position that the material muscle imbeds stamping material, utilize to hold down the material muscle and realize blocking to stamping material, thereby can avoid producing after the shaping power increase and run the material, can improve the punching press processing yield.
Drawings
Fig. 1 is a schematic structural view of a stamping die with a material blocking rib according to an embodiment of the present invention;
fig. 2 is an enlarged view of a portion a in fig. 1.
Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1-2, the embodiment of the utility model provides a stamping die of material muscle is hindered in area, including upper die base 1, die holder 2, be fixed with last terrace die 3 on the upper die base, be fixed with lower die 4 on the die holder to it is directly over die 4, its characterized in that under the terrace die 3 is located:
an annular upper stop baffle 5 capable of sliding up and down is arranged on the upper die holder 1, a plurality of upper buffer springs 9 are arranged between the upper die holder 1 and the upper stop baffle 5, the upper ends of the upper buffer springs 9 abut against the upper die holder 1, the lower ends of the upper buffer springs 9 abut against the upper stop baffle 5, an annular upper stripper plate 7 is fixed at the lower end of the upper stop baffle 5, and the upper punch 3 penetrates through the upper stop baffle 5 and the annular hole of the upper stripper plate 7 in a sliding fit manner;
an annular lower stop plate 6 capable of sliding up and down is arranged on the lower die base 2, a plurality of lower buffer springs 10 are arranged between the lower die base 2 and the lower stop plate 6, the lower ends of the lower buffer springs 10 abut against the lower die base 2, the upper ends of the lower buffer springs 10 abut against the lower stop plate 6, and the lower female die 4 penetrates through the annular hole of the lower stop plate 6 in a sliding fit manner;
the upper stop baffle 5 is positioned right above the lower stop baffle 6, a plurality of guide holes are respectively formed in the upper stop baffle 5 and the lower stop baffle 6, a plurality of vertically arranged guide pillars 8 are fixed on the upper die base 1, each guide pillar 8 respectively penetrates through each guide hole in the upper stop baffle 5 in a sliding fit manner, and each guide pillar 8 is respectively inserted into each guide hole in the lower stop baffle 6 in a sliding fit manner;
