[0021] Example 1
[0022] A stamping process for a motor shell of a new energy vehicle, comprising the following steps:
[0023] (1) Billet softening: take an aluminum alloy billet, forge or cast to form a billet, and then put it into a normalizing furnace and heat it to a temperature of 545 °C; the aluminum alloy used for the aluminum alloy billet is a heat-treated deformed aluminum alloy or casting. Aluminum alloy, preferably one of aluminum alloy grades 6061, 6063, ZL101, ZL115, ZL201, ZL203;
[0024] (2) Stretching, one-time stamping: (1) The blank is placed in an inert hot atmosphere to protect the environment, and the cooling rate of 7 °C / min is maintained; after that, the blank is subjected to a tractor at a speed of 45~70m / min. Stretch, and then pass the blank material between the die and the punch, and punch the main structure of the motor casing to form a rough blank. The total operation time of this step is controlled at 8~15min;
[0025] (3) Secondary stamping: k...

[0038] A stamping process for a motor shell of a new energy vehicle, comprising the following steps:
[0039] (1) Billet softening: take an aluminum alloy billet, forge or cast to form a billet, and then put it into a normalizing furnace and heat it to a temperature of 565 °C; the aluminum alloy used for the aluminum alloy billet is a heat-treated deformed aluminum alloy or casting. Aluminum alloy, preferably one of the aluminum alloy grades is 6061, 6063, ZL101, ZL115, ZL201, ZL203;
[0040] (2) Stretching, one-time stamping: (1) The blank is placed in an inert hot atmosphere to protect the environment, and the cooling rate of 5 °C / min is maintained; then the blank is first carried out with a tractor at a speed of 45~70m / min. Stretch, and then pass the blank material between the die and the punch, and punch the main structure of the motor casing to form a rough blank. The total operation time of this step is controlled at 8~15min;
