In the construction industry, the D-section tube bundle is widely used in heating, ventilation, air conditioning and other pipeline systems, which can effectively improve the stability and safety of the pipeline system. In the production and manufacturing process of the D-section tube bundle, a bending device is required to bend the D-section tube bundle. After bending, it becomes a product similar to a pipe clamp, which can be used as a load-bearing device in the later stage. However, when the bending equipment is required to bend the D-section tube bundle, because the tube bundle is semicircular, the conventional bending processing method is easy to damage the structure of the pipe.

[0003] Based on this, the utility model designs a D-section tube bundle production bending device to solve the above problems. Utility Model Content

A bending groove 805 is opened inside the lower end of the bending mold 804. Rubber gaskets 806 are fixedly connected to the left and right ends below the bending mold 804.

[0027] Through the structure of the above-mentioned bending assembly 8, when the D-section tube bundle is bent, it can have a larger contact area, effectively avoid stress concentration, and avoid damage to the structure of the D-section tube bundle during the bending process, thereby ensuring the quality of the bent product. At the same time, the rubber gasket 806 is made of rubber material so that the first contact point is in elastic contact, avoiding wear on the D-section tube bundle.
