1. A preparation method for copper-aluminum composite pole plate, characterized in that comprising the following steps:
step 1: heating aluminum ingot to 700-800° C. for smelting, and allowing 700-800° C.—aluminum ingot liquid to stand still for 0-30 minutes to obtain an aluminum solution;
step 2: roughening and cleaning a copper strip to complete a surface pretreatment of the copper strip;
step 3: continuously casting the aluminum strip on the aluminum solution after being left to stand;
step 4: forming pole aluminum bosses through forming roller, increasing the copper-aluminum bonding strength, and side discharging aluminum waste; forming warm roller pole aluminum copper;
step 5: molding at room temperature for the forming of fine features of the boss and the shaping of large boss;
step 6: cutting the pole, forming a battery pole product, and determining whether the battery pole product meets the standard;
wherein comparing a forming warm roller pole aluminum copper standard determination value Q with a preset forming warm roller pole aluminum copper standard determination threshold, wherein the comparison process is as follows:
if the forming warm roller pole aluminum copper standard determination value Q is greater than or equal to the preset forming warm roller pole aluminum copper standard determination threshold, then the forming warm roller pole aluminum copper meets the standard;
if the forming warm roller pole aluminum copper standard determination value Q is less than the preset forming warm roller pole aluminum copper standard determination threshold, then the forming warm roller pole aluminum copper does not meet the standard.
