DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it shall be protected by the patent law.

[0026] Example: Figure 1-4 As shown, a blanking device for punching a chain plate comprises: a blanking plate 2, a driving element 3 and a blanking trough 7, wherein the blanking plate 2 is movably arranged above the punching die 1, and the driving element 3 is connected to the rear end of the blanking plate 2 to drive the blanking plate 2 to move forward and backward. The driving element 3 adopts a cylinder or a hydraulic cylinder or an electric push rod.

[0027] The feed chute 7 is located at the front end of the feed plate 2 and fixed on the punching die 1, and is used to receive the punched chain plate pushed out by the feed plate 2.
