B) according to the width of the introduced strip-shaped aluminum piece, two rotating handles (22) are rotated to drive two control screw rods (21) to rotate, meanwhile, due to the limiting effect of two third telescopic rods, the two strip-shaped blocks (20) move, the distance between the two strip-shaped blocks (20) is changed, the suitable width is adjusted, the strip-shaped aluminum piece is subjected to left-right limiting action through a plurality of limiting rollers (25), and meanwhile, the conveying action of the strip-shaped aluminum piece is not influenced;
C) when a strip-shaped aluminum piece enters between an upper die mounting seat (1) and a lower die mounting seat (2), the strip-shaped aluminum piece is limited in the vertical direction through a plurality of driving wheels (12) on a first strip-shaped frame body (9) and a plurality of abutting wheels (26) on a second strip-shaped frame (17), when the strip-shaped aluminum piece is conveyed, two driving chain wheels (15) are driven to rotate through the work of two stepping motors (14), and the two driving chain wheels (15) drive a plurality of driven chain wheels (16) to rotate through chains, so that the driving wheels (12) are driven to rotate to convey the strip-shaped aluminum piece;
D) when punching operation is needed, the hydraulic punching device is used for working, so that the upper die mounting seat (1) moves downwards and drives the upper punching dies (4) to move downwards, the first telescopic rod (10) and the second telescopic rod (18) both contract, the strip-shaped aluminum piece is abutted against the upper punching die (4) and the lower punching die (3), the strip-shaped aluminum piece can continuously move downwards to complete punching operation through the upper punching die (4) and the lower punching die (3), and waste materials formed by punching fall through the strip-shaped blanking opening;
E) when punching the hole operation, go up the equal work of electric heater unit in punch die (4) and the lower punch die (3), carry out the oil bath heating to punch die (4) and lower punch die (3), thereby accomplish hot stamping operation when punching a hole, increase stamping quality, punch die (4) and lower punch die (3) all with bar aluminium spare contactless on the back that finishes punching a hole, when bar aluminium spare moves to lower die mount pad (2) one side simultaneously, spray water cooling to it through shower nozzle (24), make the cooling abundant.
