Round hole flanging die of wave blocking plate

Abstract

The invention relates to a round hole flanging die for a wave blocking plate. The round hole flanging die comprises a downward pressing mechanism, a male die seat, a female die seat, a mounting table and a reset mechanism. The male die seat comprises a male die and a male die guide rod, the male die is arranged below the downward pressing mechanism, and the male die guide rod is arranged below the male die; the female die seat comprises a round hole positioning die and a female die, the round hole positioning die comprises a positioning ring and a base, the base is provided with a first through hole, the female die is annular, the inner ring diameter of the female die is larger than the outer ring diameter of the male die, the female die is located on the periphery of the round hole positioning die, and the height of the female die is smaller than that of the round hole positioning die; the female die is detachably arranged on the mounting table, and the mounting table is provided with a via hole; the reset mechanism comprises a female die guide rod and a reset spring, the female die guide rod is provided with a guide hole corresponding to the male die guide rod, the female die guide rod sequentially penetrates through the first through hole, the inner ring of the female die and the via hole, and the reset spring is arranged at the bottom of the female die guide rod. The round hole flanging die is high in flanging efficiency and good in forming effect.

Description

technical field [0001] The application relates to the technical field of moulds, in particular to a round hole flanging mold for a wave breaker. Background technique [0002] The wave breaker of the road transport liquid cargo tank vehicle is generally dish-shaped, with round holes such as manholes, oil holes, and ventilation holes. Flanging the round holes can increase the rigidity of the round holes and reduce deformation and cracking. Due to the large difference in the shape of the wave breaking plate, the position of the manhole, the oil hole, and the air hole are often changed, and the size difference is large, the mold and tooling equipment with fixed upper and lower molds are not suitable for multi-variety production. [0003] At present, manual flanging with a rod with a flanging head is time-consuming and laborious, and the forming effect is poor; although it is convenient and quick to flang using a hoisting flanging machine, it is limited by the size of the structu...

AI Technical Summary

Problems solved by technology

[0004] This application provides a round-hole flanging mold for a wave-stopping plate to solve the problem of time-consuming and labor-intensive manual flanging and poor forming effect when using a rod with a flanging head in the prior art; when using a hoisting flanging machine, although it is convenient and quick, but Restricted by the structural size, it is impossible to flang small holes such as oil holes and air holes
