Abstract

The invention provides a thermoforming mold for segmented reinforcing of a boron steel material. The mold comprises an upper mold soft area forming insert shell, an upper mold soft area forming insert core, a lower mold soft area forming insert shell and a lower mold soft area forming insert core, wherein the upper mold soft area forming insert core is positioned in the upper mold soft area forming insert shell; the upper mold soft area forming insert core is internally provided with an upper mold soft area heating device; the lower mold soft area forming insert core is positioned in the lower mold soft area forming insert shell; the lower mold soft area forming insert core is internally provided with a lower mold soft area heating device. Mechanical performances of a workpiece produced by using the thermoforming mold can be realized at any position in a range that the strength of extension is 500-1500MPa, and the corresponding ductility is 15-5% according to product design needs; mold temperatures of different areas of the workpiece are controlled by independent control units, so that the control is relatively precise, and the product quality and stability are high. The mold disclosed by the invention is in a splitting shell design, and thus the mold is convenient to maintain and products are convenient to change.

Description

technical field [0001] The invention relates to the technical field of plastic forming by heat treatment, in particular to a boron steel plate, a steel pipe formed at high temperature and segmented strengthening quenching process and a mold. Background technique [0002] As a new type of ultra-high-strength hot-forming steel, automotive boron steel provides the possibility for segmental strengthening technology—the same part can adopt different heat treatment processes in different regions of the part according to the needs of automobile design, so as to obtain different strength and plasticity. The production process of the soft zone technology for hot-formed boron steel materials is divided into 4 stages: [0003] 1) Heating: heating the boron steel plate and / or steel pipe to the temperature required for heat treatment; [0004] 2) Transfer: transfer the boron steel plate and / or steel pipe to the die to be stamped; [0005] 3) Forming: Stamping and forming by mold at hi...
