Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of preventing deformation of thin-walled aluminum alloy shells from punching, in particular to an anti-deformation device for punching thin-walled aluminum alloy shells. Background Art
[0002] It is well known that when processing aluminum alloy thin-walled shells, punching the aluminum alloy thin-walled shells is an important step in the processing. However, the wall thickness of the aluminum alloy thin-walled shells is relatively thin. When punching the aluminum alloy thin-walled shells, it is easy to cause deformation of the aluminum alloy thin-walled shells at the punching locations. The deformation of the aluminum alloy thin-walled shells at the punching locations affects the quality of the shells. Most of the prior art places supports on the reverse side of the aluminum alloy thin-walled shells where holes are to be punched. The process is complicated and the punching efficiency is low. When the aluminum alloy thin-walled shell is placed on the supports, there is easily a gap between the aluminum alloy thin-walled shell and the supports. If the aluminum alloy thin-walled shell is not properly fixed, the punching locations of the aluminum alloy thin-walled shells will still be deformed. For this reason, we propose an anti-deformation device for punching thin-walled aluminum alloy shells. Utility Model Content
