The invention discloses a forming mechanism of a lithium battery base plate of a new energy automobile. The forming mechanism of the lithium battery base plate of the new energy automobile comprises a machine frame. A bottom seat is fixed to the middle of a top plate of the machine frame. An installation threaded hole is formed in the middle of the top face of the bottom seat. The bottom punching block is connected into the installation threaded hole in a threaded manner. The top face of the bottom punching block is provided with a protruding portion. Multiple step blanking holes are formed in the bottom punching block. The diameter of the upper end of each step blanking hole is small, and the diameter of the lower end of each step blanking hole is large. The upper end of the step blanking hole extends out of the top face of the protruding portion. The lower end of the step blanking hole extends downward out of the bottom punching block and communicates with a through hole of the bottom seat. The through hole of the bottom seat communicates with a main blanking hole formed in the middle of the top plate of the machine frame. A horizontal supporting plate is fixed to the lower portion of the machine frame. A collecting barrel is placed on the horizontal supporting plate. The top end face of the collecting barrel abuts against the bottom face of the top plate of the machine frame. A feeding opening of the collecting barrel faces the main blanking hole. The forming mechanism of the lithium battery base plate of the new energy automobile can achieve one-time forming and punching and automatically collect waste materials and is high in efficiency, good in effect and high in precision.
