The invention discloses circular
die cutting processing for pasting an
aluminum foil in an air bag generator, and relates to the technical field of
automobile safety part manufacturing, in particular to circular
die cutting processing for pasting the
aluminum foil in the air bag generator, which comprises the following steps of: installing a supporting bottom protective film on a circular
die cutting raw paper shaft, installing an
aluminum foil raw material on a film covering raw paper shaft, compounding by a film covering device, and rolling and
punching in a circular die
cutting unit, and stripping the bottom supporting protective film, removing waste materials and rolling a finished product. A bottom supporting protective film and an aluminum foil
raw material are respectively mounted in the middle of the
machine, and the tension is set to be 30N + / -10N and 20N + / -5N; the tension of the
machine and each link is set as required. Traditional flat
punching is replaced by rolling
punching, the taper coefficient ranges from 5% to 8%, and all shafts are consistent; the gap between the die-
cutting tool and the rolling shaft can be adjusted according to the thickness of the material, the stripping device ensures that the aluminum foil is flat, and the winding tension is matched to prevent stretching. The aluminum foil pasting
machine is suitable for aluminum foils with the thicknesses of 0.1 mm, 0.08 mm and 0.05 mm, and is used for pasting the aluminum foils in the air bag generator, the productivity is improved by 100%, and the quality is stable.
