Gas spring；
Upper mould lower end corresponds to the long stamping knife of upper mould before both sides are machined with, corresponds to the short punching of upper mould before both sides are machined with addition before described
Knife；
Upper mould lower end corresponds to the short stamping knife of upper mould after both sides are machined with after described；
The front lower mould upper end corresponds to both sides and is machined with the long stamping knife of front lower mould, corresponds to both sides in addition and is machined with the short punching of front lower mould
Knife；
Be machined with blanking groove among the workbench, the rear portion of the workbench with it is described after on mould corresponding position added with work
Make the short stamping knife of platform.
Further improved as of the invention, height and the workbench of the gas spring working face of the gas spring
Working face is consistent.
Further improved as the present invention, the long stamping knife of the preceding upper mould, the preceding upper short stamping knife of mould and the front lower mould length
Stamping knife, the front lower short stamping knife of mould form one group of kinematic pair, and its gap is 0.02-0.10mm.
Further improved as of the invention, the upper short stamping knife of mould forms one group of motion with the short stamping knife of the workbench after described
Pay, its gap is 0.02-0.10mm.
Further improved as of the invention, the noseplate, the rear bottom plate are fixed by bolt and the upper bolster and connected
Connect.
Further improved as the present invention, upper mould, the rear upper mould and the front lower modulus amount are identical before described.
Further improved as the present invention, upper mould, the rear upper mould and the front lower mould are rectangle before described.
Beneficial effects of the present invention are：By installing gas spring in surrounding while blank, and in the lower section of iron plate, disappear
De-stress concentration phenomenon, the flatness for the iron plate for making to be punched down keeps good, while incision keeps smooth；Overpay stamping knife one
Motion is played, improves operating efficiency.

Embodiment
As shown in figure 1, a kind of punching device of the embodiment of the present invention, including：Preceding upper mould 3 and afterwards upper mould 5, preceding upper mould 3 and
Upper mould 5 is fixedly mounted on 4 on noseplate 2 and rear bottom plate afterwards, and noseplate 2 and rear bottom plate 4 are bolted on upper bolster 1；
Front lower mould 9, front lower mould 9 are arranged on die shoe 8, its position and the preceding upper position correspondence of mould 3；Workbench 7, workbench 7 are arranged on
The centre of upper bolster 1 and die shoe 8；The processing blanking groove 11 among workbench 7.The gas spring working face of gas spring 10
17 height is consistent with the working face of workbench.The preceding upper long stamping knife 12 of mould and the short stamping knife 13 of preceding upper mould of preceding upper mould 3 and front lower mould
Long stamping knife 15 and the short stamping knife 16 of front lower mould form one group of kinematic pair, and its gap is 0.02-0.10mm.The upper short stamping knife 14 of mould and work afterwards
Make the short stamping knife 18 of platform and form one group of kinematic pair, its gap is 0.02-0.10mm.Noseplate 2, rear bottom plate 4 pass through bolt and upper mould
Seat 1 is fixedly connected, and preceding upper mould 3, upper mould 5 and the quantity of front lower mould 9 are identical afterwards, and preceding upper mould 3, upper mould 5 and front lower mould 9 are square afterwards
