A hot stamping experimental die

Abstract

The invention discloses a hot stamping experiment mould. The water channel parameters of the mould directly affect the cooling effect of the mould. According to the technical scheme, the hot stamping experiment mould comprises an upper mould plate, a female mould fixing plate, a male mould fixing plate, a male mould, a blank holder, a female mould, a male mould fixing plate and a support plate. The hot stamping experiment mould has the advantages that the hot stamping experiment mould can achieve rapid adjustment of the cooling water channel parameters through replacement of local modules, and the cost of remanufacturing the mould is saved; cooling modules with different cooling water channel parameters are adopted in the symmetrical positions, and a contrast experiment can be conveniently and quickly completed; and the mould is provided with a fast-replacing structure, replacement of the cooling modules can be efficiently completed, and the experiment time is saved.

Description

technical field [0001] The invention relates to a hot stamping experimental die, which belongs to the technical field of hot stamping. Background technique [0002] Hot stamping technology has a wide range of applications, and hot stamping experiments play a very important role in the exploration of hot stamping technology. The quenching process after sheet metal forming has a decisive effect on the performance of the part. The exploration of the quenching process of hot stamping must rely on the design of a reasonable hot stamping die, and at the same time, the cost of experiments must be taken into account. [0003] A thermoforming die for a combined cooling die and replaceable movable backing plate that has applied for a Chinese patent (publication number: CN103111527A, patent number: ZL 201310061985.4): This invention discloses a thermoforming die, which adopts an inverted The upper mold part is composed of die, die backing plate, upper die seat, upper die backing plate...

AI Technical Summary

Problems solved by technology

At present, there are still a series of problems in the field of hot stamping, such as: 1. Replacing molds with different water channel parameters requires a lot of resources and increases the cost of experiments. The influence of water channel parameters on the cooling performance of the mold is still in the simulation stage

2. Interference between the cooling water channel of the mold and the joints of the water supply and outlet pipes often occurs, resulting in difficulties in the installation of the joints

3. When the heated sheet is placed on the blank holder, the temperature of the part in contact with the blank holder will drop rapidly, resulting in a large temperature drop of the sheet before the stamping starts, which affects
