Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, and more specifically, to a fixing device of an aluminum alloy profile punching machine. Background Art

[0002] A punching machine is often used to punch holes in aluminum alloy profiles during processing. However, the length of the profile is generally set to be relatively long.
