[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021]

[0022] Figures 1 to 4 The utility model provides a technical scheme: a pipe bending wheel mold is used for local bending of pipe material, and can drive the pipe material to realize multi-angle bending forming.

[0023] The pipe bending wheel mold comprises an upper wheel mold 1, a lower wheel mold 2 and a bending rod 3. The upper wheel mold 1 and the lower wheel mold 2 are each provided with a positioning groove for placing pipe material. The two positioning grooves form an adjusting groove 201 matched with the outer surface of the pipe material after cooperation. The adjusting groove 201 is mainly a forming groove of the pipe material.
