Lower die structure of magnetic-conducting piece blanking die

Abstract

The invention relates to the technical field of dies and discloses a lower die structure of a magnetic-conducting piece blanking die. The lower die structure comprises a female die and a lower formwork, and the female die is installed on the lower formwork. The lower die structure further comprises an adjusting mechanism and a material-stripping mechanism, wherein the adjusting mechanism is installed on the lower formwork to be used for adjusting horizontal displacement of the female die, and the material-stripping mechanism is arranged at the upper end of the female die to be used for material stripping after stamping. The adjusting mechanism comprises an adjusting ring and a plurality of adjusting screws, wherein the adjusting ring is installed on the lower formwork and located on the outer side of the female die, and the adjusting screws are installed in the circumferential direction of the adjusting ring. According to the lower die structure, on one hand, the adjusting mechanism is adopted to adjust horizontal displacement of the female die, so that intervals between the female die of the whole die and a male die are uniform so as to improve cross section smoothness and precision of blanking magnetic-conducting pieces, on the other hand, the material-stripping mechanism is adopted to perform material stripping, and the problem of blockage in material discharging is solved.

Description

technical field [0001] The invention relates to the technical field of moulds, and more specifically relates to a lower die structure of a magnetic sheet blanking die. Background technique [0002] The magnetic guide sheet is an important part on the horn. The processing of the magnetic guide sheet in the prior art mainly adopts precision machine tools or molds for production, and its existing problems are: on the one hand, the cost of precision machine tools and molds is relatively high; However, during the use of precision molds, the processing accuracy requirements cannot be fully guaranteed. At the same time, after the mold is blanked, the upper mold is prone to jamming. Therefore, a new mold structure needs to be designed. Contents of the invention [0003] The object of the invention is to provide a lower mold structure of the magnetic sheet blanking mold with low cost, high machining accuracy and less prone to material jamming. [0004] In order to achieve the abo...
