Description

Metal sheet cutting machine

Technical Field

The utility model relates to the technical field of metal sheet processing, in particular to a metal sheet cutting machine.

Background Art

In the current field of metal heat exchangers, the heat transfer surface area of the heat exchange device is usually increased by adding a metal sheet with strong thermal conductivity to the surface of the heat exchange device where heat transfer is required. The metal sheet with this function is called a metal sheet. The metal sheet is usually an aluminum or copper metal sheet. In the processing of metal sheets, a cutting machine is usually used to cut the metal sheet.

According to the patent number CN214024089U, a fully automatic cutting machine for metal sheets is disclosed. The device can clamp the metal sheets into the slots set on one side of four fixed plates, and then cut the metal sheets through the laser component and the laser cutting head.
