Fine-adjustment coining mechanism

Abstract

The invention relates to a stamping mold, in particular to an inverse-stamping type fine-adjustment coining mechanism. The fine-adjustment coining mechanism comprises an upper mold frame, an upper mold body, a lower mold frame, a lower mold body and a discharging plate arranged on the molded surface of the upper mold body, and further comprises a jacking and pressing rod, a rotating semicircular part and a flanging male mold, wherein the jacking and pressing rod, the rotating semicircular part and the flanging male mold are sequentially connected. The upper end of the jacking and pressing rod is fixed into the upper mold body, the other end of the jacking and pressing rod extends to the portion below the lower mold body, the rotating semicircular part is installed on the lower mold frame, one end of the upper surface of the rotating semicircular part abuts against the lower end of the jacking and pressing rod, the other end of the upper surface of the rotating semicircular part abuts against the lower end of the flanging male mold, the upper end of the flanging male mold is in a frustum shape, a polyester elastomer is arranged between the upper mold body and the discharging plate, and the rotating semicircular part is hinged to the lower mold frame and is hemispherical. By means of the fine-adjustment coining mechanism, the defect that in the prior art, lever adjustment positioning is inaccurate is overcome, and the fine-adjustment coining mechanism is accurate in positioning when running at a high speed.

Description

technical field [0001] The invention relates to a stamping processing die, in particular to a backflushing type fine-tuning embossing mechanism. Background technique [0002] Most of the existing stamping-type forming processes use the combination of the die and the punch to carry out the punching process. For example, the Chinese patent CN201676964 discloses a terminal complex bending punching and riveting one-time forming die, which has a lower die base and an upper die base. There is a concave formwork on the base of the lower mold, and the base of the upper mold is connected with the fixing plate and the stripper plate downwards. There are 90-degree bending structures, 60-degree bending structures inwards and 30-degree upward bending structures on the upper and lower mold bases. This terminal complex bending punching and riveting one-time forming mold has multiple process stations with different bending angles on one mold, realizing step-by-step continuous production of ...

Problems solved by technology

[0003] However, the lever used in the Chinese patent CN201676964 is a straight rod. In the actual work process, the end of the lever often trembles due to the excessive punching speed, which makes the adjustment and positioning of the lever inaccurate.
