8. The bevel hole flanging device as claimed in claim 7, wherein a wedge-shaped block is arranged at the bottom of the upper die; the pushing mechanism comprises a sliding block arranged on the lower die, and the sliding block is provided with a first inclined surface matched with the punch head structure and a second inclined surface matched with the wedge-shaped block; and when the die is closed, the wedge block descends, abuts against the first inclined surface and pushes the sliding block to move horizontally so that the second inclined surface abuts against the punch structure and pushes the punch structure to move obliquely upwards.
9. The bevel reaming device of claim 8, wherein said pushing mechanism further comprises a second elastic mechanism, said second elastic mechanism comprising:
the stop block is fixed on the lower die;
one end of the second pull rod is fixed on the sliding block, and the other end of the second pull rod penetrates through the stop block; a second spring is clamped between one end of the second pull rod, which is far away from the sliding block, and the stop block; the second spring contracts when the slider moves toward the punch structure.
10. The inclined plane hole flanging device of claim 9, wherein the upper part of the lower die is provided with a slide rail, and the bottom of the slide block is provided with a slide groove matched with the slide rail.
