The method for using the rapid punching and forming device based on bus duct aluminum bar according to claim 1 is characterized in that: S1: Start the machine and load the material: the equipment is powered on and the aluminum bar (4) is transported from the feeding unit (3) to the punching unit (9) and the bending and forming unit (2) for production; S2: Material conveying, punching, and bending: The aluminum bar (4) is conveyed by the feeding unit (3), punched by the punching unit (9), and finally bent according to requirements by the bending unit (2) to complete the production; S21: During the punching process, the movable end of the lifter (8) moves downward, and firstly controls the upper die mounting plate (92) through the guide mechanism (93) to drive the upper die to move downward, and the upper die moves downward and cooperates with the lower die (95) to complete the punching of the aluminum row (4); S3: Pre-installing the molds according to the needs of the next batch of punching holes: According to actual needs, the upper molds and lower molds (95) required for the next batch of punching holes of different specifications are installed on the lower end of the unused mounting plate main body (921) and the upper end of the lower mold installation mechanism (94). During the installation process, the position of the clamping plate (946) can be adjusted by rotating the second threaded rod (947) to fix the lower mold (95) through the clamping plate (946). At the same time, the installation height of the lower mold (95) can be finely adjusted by rotating the first threaded rod (9452) to adapt to the needs of punching holes in aluminum bars (4) of different thicknesses; S4: Replace the pre-installed mold and put it into production: the entire equipment is stopped, and the upper mold installation plate (92) is controlled by hand to move the built-in sleeve (932) downward, and the built-in sleeve (932) is separated from the bottom of the movable end of the lifter (8), and then one end of the pre-installed mold is pushed to the side of the movable end of the lifter (8), and then connected to the bottom of the movable end of the lifter (8) through the built-in sleeve (932) to complete the positioning; S5: According to the needs of bending and forming, the bending program is set and production starts: the program of the bending and forming unit is set according to the actual production needs, and then the entire equipment is powered on, and the next batch of aluminum bars (4) to be produced are fed into the feeding unit (3) for production.
