Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device used for producing aluminum-plastic combined covers. Background Art

[0002] The production of aluminum-plastic combination covers is generally divided into three main steps, including the forming of the aluminum cover, the forming of the plastic sheet, and the riveting of the plastic sheet and the aluminum cover. The corresponding production device of the aluminum-plastic combination cover is composed of an aluminum cover forming unit, a plastic sheet forming unit and a riveting unit.

[0003] For example, the stamping device for producing aluminum-plastic composite caps for infusion bottles with the authorization announcement number "CN213162520U" uses a pressing roller and a pressing column to move the pressing roller back and forth in a horizontal position to flatten the small aluminum sheet. After the small aluminum sheet is flattened, it is placed in the pressing groove, and the pressing column punches the aluminum cap out of the through hole and drops it into the receiving box. The device can punch a large number of aluminum caps at one time, greatly improving work efficiency. However, when the device is punching the aluminum sheet, the aluminum sheet must be flattened first, and then the operator manually places the flattened aluminum sheet on the surface of the pressing plate. When the device is punching the aluminum sheet, the pressing column punches the pressing plate when the pressing plate lacks support, causing the pressing plate to be overstressed and damaged, resulting in the internal aluminum cap not being able to fall from the through hole into the receiving box, and unable to discharge the material normally, resulting in an increase in the workload of the operator and a reduction in the work efficiency of the device.
