Abstract

The invention relates to a preparation process of a heatable aluminum foil packaging lunch box, which uses punch forming equipment. The punch forming equipment comprises a bottom plate, a workbench, amounting frame, a punching device and a material placing device, and the specific process flow for preparing the aluminum foil packaging lunch box by adopting the punch forming equipment is as follows: aluminum foil cutting, aluminum foil transferring, punch forming, edge pressing processing and discharging stacking; a punching device comprises a lifting air cylinder, a mounting block, a punchinghead and an edge pressing mechanism. According to the preparation process of the heatable aluminum foil packaging lunch box provided by the invention, an aluminum foil is punched and formed through the cooperation of the material placing device and the punching device, so that the flaky aluminum foil is made into a lunch box finished product, edge pressing treatment can be conducted on the lunchbox in the punching process at the same time, production equipment for edge pressing of the lunch box does not need to be additionally arranged, and in the aluminum foil moving process, the aluminum foil is guided and positioned in an air blowing mode, position deviation of the aluminum foil is avoided, and meanwhile aluminum foil deformation caused by extrusion is avoided.
