Cold stamping die for aluminium foil container

Abstract

The present invention discloses a cold stamping die for aluminium foil container, which completes the whole processing through once stamping, mainly comprising an upper die composed of an upper die holder, an upper die cylinder arranged on the upper die holder, an ejector cylinder, an upper pressing side liner plate and a stretching base arranged on the piston rod of the upper die cylinder, an ejecting block arranged on the piston rod of the ejector cylinder and an upper pressing side arranged on the upper pressing side liner plate and a lower die composed of a lower die holder, a lower die cylinder, a support plate and a secondary stretching base arranged on the lower die holder, a secondary stretching male die disposed on the secondary stretching base, a stretching forming male die arranged on the secondary stretching male die, a lower pressing side liner plate arranged on the piston rod of the lower die cylinder, a lower pressing side ring arranged on the lower pressing side liner plate and a lower shearing plate arranged on the support plate. The cold stamping die can complete the whole processing of aluminium foil container and aluminium foil tableware through once stamping, therefore, processing efficiency is improved and labor intensity is lowered.

Description

technical field [0001] The invention relates to a cold stamping die, in particular to a cold stamping die for an aluminum foil container. Background technique [0002] With the increasing awareness of environmental protection in the whole society, recyclable aluminum foil containers will be more and more popular, because it replaces plastic foam containers, one of the "white pollution", and also improves the grade. It can be said to kill two birds with one stone. In fact, aluminum foil packaging and aluminum foil tableware have been widely used in foreign developed countries, and aluminum foil packaging and aluminum foil tableware have become the first choice for aviation meal boxes and aviation food packaging. [0003] As we all know, when processing aluminum foil packaging and aluminum foil tableware, it is usually necessary to go through four processes of cutting → stretching → stretching → curling to complete the entire processing process. The current cold stamping die...

AI Technical Summary

Problems solved by technology

The current cold stamping die cannot integrate these four processes together

Therefore, the entire processing process cannot be completed in one stamping process, which makes the processing efficiency of aluminum foil packaging and aluminum foil tableware lower, and also increases labor intensity.
