fig. 2 is a schematic view of a sectional stamping structure of the blanking die provided in this embodiment.

Detailed Description

The sectional stamping structure of the blanking die of the present invention is further described with reference to fig. 2.

The utility model provides a segmentation stamping structure of blanking die, includes blanking terrace die 5 and die plate 6, characterized by: a female die 20 is arranged in the central hole of the female die plate 6, a blanking cavity 7 is formed between the female die 20 and the central hole of the female die plate 6, and a punching male die 10 is arranged in the blanking cavity 7. The profile blanking position 71 and the central hole blanking position 72 are distributed in the depth direction of the blanking cavity 7, and the upper end of the punching male die 10 is positioned on the central hole blanking position 72; on the lower end face of the cutting punch 5, a punching cavity 51 is provided, which punching cavity 51 corresponds to the punching punch 10.

Based on the structure, when in specific blanking, the blanking male die 5 punches downwards, the blanking part on the raw material 3 is pressed into the outline blanking position 71 of the blanking cavity 7, and the outline of the product 4 is firstly blanked; the blanking male die 5 continues to press the product 4 down to the center hole blanking position 72, and the product 4 is punched by the blanking male die 10 during the pressing down process because the center hole blanking position 72 is provided with the blanking male die 10. In the above-mentioned in-process, the profile blanking and the time sharing of central hole blanking of product 4 go on, so required pressure is showing the reduction when blanking, makes the utility model discloses can adapt to more different hardness raw and other materials 3's blanking.

A product 4 ejection assembly 8 is arranged in the blanking cavity 7; the product 4 ejection assembly 8 comprises a top plate 81 and an ejector rod 82; the top plate 81 is arranged in the blanking cavity 7 and can move up and down in the blanking cavity 7; the ejector rods 82 are provided with a plurality of ejector rods 82, the upper end of each ejector rod 82 is supported on the top plate 81, and the lower end of each ejector rod 82 penetrates through the bottom wall of the blanking cavity 7 to be connected with a jacking component which is an oil cylinder.
