Description

Technical fields:

[0001] This utility model relates to the technical field of copper tube processing equipment, and more specifically to a cutting device for manufacturing U-shaped copper tubes. Background technology:

[0002] U-shaped copper pipes are copper pipes bent into a U-shape. They possess excellent corrosion resistance, thermal conductivity, and weldability, and are widely used in industry, construction, and energy fields. Current U-shaped copper pipe manufacturing involves cutting long, straight copper pipes into short sections, which are then bent into U-shapes using bending equipment. This bending process requires repeated loading and unloading of short sections, consuming significant time. However, some copper pipe bending equipment on the market can cut continuous S-shaped copper pipes into individual U-shaped pipes, reducing the need for repeated loading and unloading. Therefore, changing the process from cutting before bending to bending before cutting can improve production efficiency. To implement this bending-then-cutting process, a cutting device capable of producing continuous S-shaped copper pipes needs to be developed. Utility Model Content:
