Hot stamping plate material positioning unit

Abstract

The invention discloses a hot stamping plate material positioning unit. The hot stamping plate material positioning unit comprises a positioning nail and a positioning nail spring, and further comprises a loading nail and a loading nail spring. One end of the positioning nail is provided with a convex edge. A big section of inner hole and a small section of inner hole are formed in the loading nail. The positioning nail is arranged in the two sections of inner holes, and relatively axially slides with the loading nail. One end of the bigger inner hole of the loading nail is provided with a positioning nail spring seat. The positioning nail spring is compressed between the positioning nail spring seat and the positioning nail. The positioning nail stretches out from the interior of the positioning nail. The outer wall of the loading nail is provided with wing loops, and the loading nail is arranged in a corresponding step hole of a lower mould, and can relatively axially slide with the lower mould. The lower mould is provided with a loading nail spring seat at one end of the holes corresponding to the wing loops. The loading nail spring is compressed between the wing loops and the loading nail spring seat. The loading nail stretches out from the lower mould and protrudes out of the upper surface of the lower mould. According to the hot stamping plate material positioning unit, heat loss resulting from contact of a high temperature steel plate and the surface of a mould is prevented effectively, the mould does not need to be heated, the time of single piece forming is short, and the efficiency is high; and the structure is simple and reasonable, the manufacture cost is low, installation and maintenance are convenient, and the universality is good.

Description

technical field [0001] The invention belongs to the technical field of forging processing machinery, and in particular relates to a hot stamping sheet material positioning unit. Background technique [0002] Due to the low hardness of the steel plate formed by cold stamping, it is increasingly unable to meet people's use needs. In order to increase its strength, the only way to increase its thickness is to increase the overall weight, which does not meet the weight requirements of many projects. Require. [0003] At present, the application of hot stamping forming technology is more and more. The hot stamping forming technology is to heat and keep the steel plate. Pressure, the built-in cooling device in the mold cools the mold, and uses the low temperature of the mold parts in contact with the steel plate to heat treat the steel plate to obtain a uniform martensitic structure and increase the hardness of the steel plate, which can make the steel plate thin and hard, meetin...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the above-mentioned deficiencies existing in the prior art, the technical problem to be solved by the present invention is to provide a positioning unit for hot stamping sheets, so as to avoid the problem of heat loss caused by the contact between the high-temperature steel plate and the surface of the mold, and to effectively prevent the contact between the high-temperature steel plate and the surface of the mold. And the structure is simple, the effect of low cost and easy implementation
