Description

Technical Field

[0001] This utility model relates to the field of vacuum hot pressing forming technology, and in particular to a vacuum hot pressing forming device for metal composite plate assemblies. Background Technology

[0002] Metal composite plates refer to composite plates made by laminating one metal layer with another, aiming to save resources and reduce costs without compromising performance (corrosion resistance, mechanical strength, etc.). They are widely used in aerospace, new energy batteries, and other fields. Vacuum hot pressing equipment is the core equipment for the efficient preparation of such materials. It applies high temperature and pressure in a vacuum environment, promoting diffusion bonding between the metal layers. Hot pressing is a thermal principle; due to its high pressure, low temperature, and short pressing time, it can solve the deformation problem of composite plates, greatly reducing the degree of deformation.

[0003] Current vacuum hot pressing processes face the prominent problem of interlayer misalignment: conventional presses rely solely on mechanical positioning pins to prevent displacement, which, under high-temperature conditions, can easily lead to shear slippage at the composite interface due to differences in the thermal expansion coefficients of metals. Experimental data shows that the interlayer misalignment of steel composite plates can reach 0.8 mm, directly causing a 40% decrease in interfacial bonding strength. Existing devices lack sufficient precision in preventing displacement during hot pressing, and the noise generated during vacuum hot pressing is relatively high, with inadequate noise reduction and sound absorption effects. Therefore, we propose a vacuum hot pressing device for metal composite plate components to address these issues. Utility Model Content

It can be stably lifted and lowered within the column thread of the lifting limit column 4. The anti-deviation limit is stable and the lifting accuracy is high. After the hot pressing upper mold 3 and the vacuum lower mold 2 are closed, the vacuum hot pressing quality is excellent. When the mold is closed, the top mold closing gasket 23 and the bottom mold closing gasket 22 form a vacuum protection, which improves the vacuum hot pressing quality. At the same time, the top mold closing gasket 23 and the bottom mold closing gasket 22 play a noise reduction and sound insulation effect, which improves the noise reduction quality.
