Description

Technical Field

[0001] This utility model relates to the field of refrigeration processing, and in particular to a multi-purpose copper pipe welding device. Background Technology

[0002] In refrigeration-related processing and production fields, multiple copper pipe structures are required to achieve cooling and heat dissipation. Because refrigeration equipment requires a large number of copper pipes, and these pipes often need to be formed into unconventional bends, and because the paths within the copper pipes cannot be satisfied with a single inlet or outlet, welding is necessary to achieve multiple flow paths. Conventional welding equipment is not well-suited for welding irregularly shaped copper pipe structures, and manual welding with limited positioning is dangerous and cannot accurately align the joints to be welded, affecting welding quality and efficiency.

[0003] Therefore, it is necessary to provide a multi-purpose copper pipe welding device to overcome the defects mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a multi-purpose copper tube welding device that enables the welding of irregularly shaped copper tube structures, reduces welding difficulty, and improves welding accuracy and efficiency.

[0005] According to one aspect of the present invention, a multi-purpose copper pipe welding device is provided, comprising a bottom support, an operating plate disposed above and connected to the bottom support, and a limiting component disposed on and connected to the operating plate. The bottom support includes a connecting block, and the bottom surface of the operating plate includes a connecting groove.
