Abstract

The utility model discloses a split type bolt punching die female die structure. The split type bolt punching die female die structure is characterized by comprising a female die body and a connecting sleeve. The connecting sleeve is internally provided with a containing cavity matched with the female die body in appearance and size. The female die body is arranged in the containing cavity of the connecting sleeve. The female die body is of a split type structure and is formed by matching at least two sections of female die units. The female die units are correspondingly internally provided with cavities. The connecting sleeve is of a split type structure and is formed at least by connecting an upper connecting sleeve body and a lower connecting sleeve body, and the two ends of the upper connecting sleeve body and the two ends of the lower connecting sleeve body are provided with openings. The female die body of the split type bolt punching die female die structure is of the split type structure and is connected through the connecting sleeve, after the female die unit on the topmost layer is damaged, only the damaged female die unit needs to be replaced, the whole female die body does not need to be replaced, and the split type bolt punching die female die structure has the advantages of saving materials and reducing machining cost.
