Method for manufacturing high strength steel plate hot stamping die

Abstract

The invention discloses a method for manufacturing a high strength steel plate hot stamping die and belongs to the technical field of hot stamping forming. Aims at the manufacturing problem that shape follow-up cooling water channels are arranged in bent molded surfaces of male and female dies of the hot stamping die, the method is disclosed. The method comprises the following steps of: firstly, according to the shapes of the molded surfaces of the male and female dies of the die, bending the cooling water channels and connecting the cooling water channels into a pipeline system; then dividing the male and female dies into processing blocks according to the shape follow-up cooling water channels and processing grooves for placing the shape follow-up cooling water channels; and placing the shape follow-up cooling water channels into the grooves; and correspondingly combining and fixing the processing blocks to form a male and female die structure in which the shape follow-up cooling water channels are arranged. The method adopts the process scheme of manufacturing the cooling water channels, cutting the male and female dies, processing the grooves of the cooling water channels, placing the cooling water channels into the grooves and combining and fixing the male and female die processing blocks. According to the process scheme, the hot stamping die of which the cooling water channels follow up the shapes of the molded surfaces of the male and female dies and are at the equal distances with the molded surfaces of the male and female dies of the die can be manufactured; and a high strength steel plate hot stamping part with a uniform cooling effect can be processed by the die.

Description

Technical field: [0001] The invention provides a method for manufacturing a high-strength steel plate hot stamping die, which belongs to the technical field of hot stamping forming. Background technique: [0002] Energy saving, environmental protection, safety, and comfort are the general trends in the development of the automobile industry today, and reducing fuel consumption, energy saving, and emission reduction are hot issues of global concern today. The lightweight technology of automobiles is undoubtedly an effective way to solve this problem. However, in order to realize the lightweight of the car, in addition to optimizing the design of the car structure, it is also possible to use lightweight materials to manufacture car body components. As a typical representative of lightweight materials, high-strength and ultra-high-strength steel plates have become one of the most important means of lightweighting automobiles due to their light weight and high strength.
