wherein, in the process of descending or ascending along with the blanking and cutting plate (734), the blanking prepressing plate (736) can ascend or descend relative to the blanking and cutting plate (734) along the vertical direction to switch between a prepressing state and a natural state when contacting with or gradually separating from the blanking bearing platform (739).

6. The cutting and feeding device according to claim 5, wherein a buffering return member (7364) is elastically connected between the cutting pre-press plate (736) and the cutting blade (734), the buffering return member (7364) acting on the cutting pre-press plate (736) such that the cutting pre-press plate (736) can be lowered in a vertical direction with respect to the cutting blade (734) while gradually separating from the cutting bed (739) to return from the pre-pressed state to the natural state in the course of ascending with the cutting blade (734).

7. The cutting and feeding device as claimed in claim 5, wherein a cutting head (735) is embedded in the bottom of the blanking plate (734) and abuts against the blanking prepressing plate (736), and the blanking plate (734) is driven by the blanking driver (733) to descend along the blanking channel (7321) to drive the cutting head (735) to cut the workpiece along the edge of the blanking platform (739).

8. The cutting and feeding device according to claim 7, characterized in that the bottom of the blanking prepress plate (736) is formed with at least two prepress heads (7362), each prepress head (7362) being at least partially embedded in the blanking head (735) and being slidably connected to the blanking head (735) in a vertical direction, the prepress heads (7362) protruding from the bottom surface of the blanking head (735) when the blanking prepress plate (736) is in the natural state.

9. The cutting and feeding device as claimed in claim 8, wherein a bottom surface of each of said pre-pressing heads (7362) is formed with a corresponding one of the pre-pressing guide posts (7363) protruding downward.
