Description

Technical Field

[0001] This utility model relates to the technical field of thermos cup processing equipment, specifically to a laser cutting machine for irregularly shaped cups. Background Technology

[0002] The manufacturing process of a thermos cup involves several stages to transform the initial stainless steel into a beautifully crafted thermos. There are two methods for processing the outer shell of an irregularly shaped thermos cup (non-cylindrical). One method involves separately manufacturing the rim, body, and base, then welding them together. This method requires multiple cutting and welding steps. The other method involves first stamping two symmetrical, irregularly shaped semi-shells from stainless steel, then using wire cutting to remove excess material around the semi-shells before welding them together. However, the wire cutting method requires cutting the rim after welding, and the semi-shells cannot be completely fixed during the cutting process, leaving space for the cutting. This results in significant deformation of the finished cup body, affecting subsequent welding processes. Utility Model Content
