The invention discloses a steel pipe bending forming mold with a controllable bending angle. The steel pipe bending forming mold structurally comprises a base, a steel pipe compressing mechanism, a steel pipe and a bending mold. The steel pipe compressing mechanism and the bending mold are sequentially fixed to the base. The steel pipe in contact with the bending mold is placed in the steel pipe compressing mechanism. Compared with the prior art, the steel pipe bending forming mold has the advantages that the steel pipe bending forming mold can be suitable for steel pipes of different specifications, and therefore the steel pipes of different specifications are clamped; the steel pipe can be effectively prevented from loosening in the bending process after clamping is carried out, the bending precision is effectively improved, and the steel pipe can evenly bear clamping force; the stability of the steel pipe in the bending process is further improved, and the problem that steel pipe bending goes wrong due to the fact that the steel pipe loosens in the bending process is further avoided; and the rotating angle of an upper mold bending wheel is proportional to the bending angle of the steel pipe, different bending needs on the steel pipe can be met through only one bending mold, and the manufacturing cost of the steel pipes is reduced.
Description
technical field [0001] The invention relates to the technical field of moulds, in particular to a steel pipe bending and forming mold with controllable bending angles. Background technique [0002] Steel pipe tables and chairs are mainly made of steel pipes, with better quality and unique shape, so they are loved by people. Most steel pipe tables and chairs need to bend steel pipes in the production process to obtain the required shape. In order to ensure the bending Generally, the bending forming mold is used for the bending and forming of steel pipes. [0003] Due to the imperfect technology of existing steel pipe bending and forming molds, bending steel pipes with different angles need to be used in the production of steel pipe tables and chairs, and different bending angles require different bending molds, so multiple sets of bending are required Molds virtually increase the production cost of steel pipe tables and chairs. Contents of the invention [0004] The main ...
