in the figure: the device comprises a main shaft 1, a platform 2, an upper die 3, an upper bottom plate 4, a connecting plate 5, an upper fastening plate 6, a spring 7, a knife edge 8, a lower die 9, a lower bottom plate 10, a positioning block 11, a lower fastening plate 12, a positioning guide pillar 13, a material pushing device 14, a supporting seat 15 and a positioning groove 16.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the blanking clamp for producing the elastic pin comprises a main shaft 1 and a platform 2, wherein the platform 2 is right opposite to the lower part of the main shaft 1; the upper die 3 comprises an upper bottom plate 4, a connecting plate 5, an upper fastening plate 6 and springs 7, wherein the upper bottom plate 4 is fixed at the lower end of the main shaft 1, the connecting plate 5 is fixed with the upper bottom plate 4 through bolts, and the upper fastening plate 6 is connected with the connecting plate 5 through a plurality of springs 7; the knife edge connecting device further comprises a knife edge 8, and the knife edge 8 is fixed in the middle of the connecting plate 5 through bolts. Since the knife edge 8 is fixed to the coupling plate 5 and the connecting spring 7 for the upper fastening plate 6 is retractable, the upper fastening plate 6 is retracted upward to expose the knife edge 8 when the upper die 3 is pressed downward.

In order to position a workpiece to be cut, the cutting device further comprises a lower die 9, wherein the lower die 9 comprises a lower bottom plate 10, a positioning block 11 and a lower fastening plate 12, the lower bottom plate 10 is arranged on the platform 2, the lower fastening plate 12 is fixed with the lower bottom plate 10 through bolts, the positioning block 11 is fixed on the surface of the lower fastening plate 12, and the workpiece can be positioned between the positioning blocks 11 which are parallel.

In order to ensure that the knife edge 8 is exposed in space when the upper die 3 is pressed down, the upper fastening plate 6 is of a square frame structure, and the middle hollow part corresponds to the position of the knife edge 8.
