The present invention discloses an aluminum foil forming machine with a smoothing structure and a smoothing method thereof, belonging to the technical field of metal auxiliary processing. The aluminum foil forming machine includes a stamping forming machine, a base is installed on the stamping forming machine, a lower mold is installed on the top of the base through bolts, an upper mold installed on the output end of the hydraulic cylinder on the stamping forming machine is arranged above the lower mold, and guide rollers are installed on both sides of the top of the base. The present invention drives two swing arms to rotate in opposite directions with the shaft rod as the axis through a driving component, so that the clamping roller is pressed on the aluminum foil, and the clamping roller and the swing arm are limited by the damping installation component to ensure that the clamping roller does not rotate too fast to affect the tensioning effect, and the clamping roller does not stop rotating and excessive tension tearing occurs, so that the aluminum foil to be stamped can be properly tightened and smoothed before each stamping, so as to avoid loose wrinkles and excessive tension tearing of the aluminum foil and ensure the quality of aluminum foil stamping.

The invention discloses an aluminum foil forming machine with a smoothing structure and a smoothing method of the aluminum foil forming machine, and belongs to the technical field of metal auxiliary machining. The aluminum foil forming machine comprises a stamping forming machine, a bearing platform is installed on the stamping forming machine, and a lower die is installed at the top of the bearing platform through bolts; an upper die installed at the output end of an upper hydraulic cylinder of the stamping forming machine is arranged above the lower die, and guide rollers are installed on the two sides of the top of the bearing platform. The two swing arm rods are driven by the driving assembly to rotate oppositely with the shaft rod as the axis, the pressing roller is pressed on aluminum foil, the pressing roller and the swing arm rods are limited through damping of the damping installation assembly, it is guaranteed that the pressing roller cannot rotate too fast to affect the tensioning effect, the pressing roller cannot rotate and cannot be excessively tensioned and torn, and the purpose that the pressing roller cannot rotate too fast before punching every time can be achieved. The aluminum foil to be stamped is properly tensioned and smoothed, so that the aluminum foil is prevented from being loosened, wrinkled and torn due to excessive tensioning, and the stamping forming quality of the aluminum foil is guaranteed.
