Heat treatment method for vehicle body shell for new energy vehicle

Abstract

The invention discloses a heat treatment method for a vehicle body shell for a new energy vehicle. The heat treatment method comprises the following steps: setting a heat treatment solution furnace to ensure the temperature to rise to 450-550 DEG C, and setting an ageing furnace to ensure the temperature to rise to 200-300 DEG C; hanging an anterior shock absorber to the machine side by using a heat treatment material frame, placing a product on a special material frame in a manner of corresponding deformation points to supporting points one by one, and ensuring the anterior shock absorber to automatically enter the heat treatment solution furnace by using the heat treatment material frame to carry out heat preservation; after the heat preservation time of the heat treatment solution furnace is over, automatically shifting the anterior shock absorber into a cooling chamber by using the heat treatment material frame; automatically starting a strong air cooler; after air cooling is finished, ensuring the anterior shock absorber to automatically enter the ageing furnace by using the heat treatment material frame; and after heat preservation of the ageing furnace is finished, ensuring the anterior shock absorber to automatically enter a product blanking area through a track by using the heat treatment material frame. The heat treatment method has the advantages that by using the air cooling process to replace the water cooling process, the mechanical property requirements of clients and the overall deformation requirements for the product are met; and with the improvement of the deformation phenomenon in the heat treatment process, the production efficiency is improved.
