Aluminum foil lunch box forming processing technology

Abstract

The invention relates to an aluminum foil lunch box forming processing technology, which uses automatic forming equipment. The automatic forming equipment comprises a substrate, a mounting frame, a stamping device and a positioning device; The specific process flow when using the above automatic forming equipment to manufacture an aluminum foil lunch box is as follows: aluminum foil cutting, aluminum foil positioning, equipment adjustment, pressing formation, and lunch box taking out; the stamping device comprises a support base, a bearing table, a stamping die, a stamping cylinder and a working frame; and the stamping die includes a central die head, a No. 1 ring die, a No. 2 ring die, a No. 3 ring die, a connecting rod, a linkage bolt, a fixed cylinder and a lifting rod. According to thealuminum foil lunch box forming processing technology provided by the invention, the stamping die is designed using a concentric circle principle, and aluminum foil lunch boxes with various specifications can be produced by using one die, so that the cost of purchasing equipment by manufacturers is greatly reduced, and the aluminum foil can be positioned through the positioning device, so as to eliminate the problem that the aluminum foil slides in the stamping process to affect the accuracy of a stamping operation.

Description

technical field [0001] The invention relates to the technical field of food packaging lunch box processing, in particular to an aluminum foil lunch box forming process. Background technique [0002] Aluminum foil is a hot stamping material that is directly rolled into thin sheets by metallic aluminum. Its hot stamping effect is similar to that of pure silver foil hot stamping, so it is also called fake silver foil. Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, medicines, photographic substrates, household daily necessities, etc., and is usually used as its packaging material, among which aluminum foil lunch boxes are more common in daily life. [0003] Aluminum foil lunch box is a kind of tableware that is widely used. It is a product that is formed by one-time automatic cold stamping with special equipment and molds, using aluminum foil mother roll as raw material. At present, there are some common problems in the forming proc...

AI Technical Summary

Problems solved by technology

[0004] (1) The size of the stamping die used in stamping is fixed, so it can only be processed for one specification of lunch boxes. In order to produce various specifications of lunch boxes, it is necessary to configure multiple stamping equipment or frequently replace stamping molds of different sizes , increasing the manufacturer's operating costs;

[0005] (2) Due to the light material of the aluminum foil, the aluminum foil is easy to slide relative to the stamping die during the stamping process, resulting in deviations between the shape and size of the lunch box made after stamping and the designed shape and size, and the same batch of lunch boxes cannot be guaranteed The consistency of appearance affects the factory quality of the product
