Abstract

The invention provides an internal high pressure forming die. The shape of a cavity (1) of the die is matched with that of a formed pipe, and grooves (11) are arranged on the inner wall of the cavity (1) and correspond to bent positions of the pipe. When the internal high pressure forming die is used for manufacturing the pipe, as the grooves (11) are arranged on the inner wall of the cavity (1) and correspond to the bent positions of the pipe, projections are arranged at the bent positions of the formed pipe, the arc length of the bent positions of the pipe is increased by the aid of the protections, and further the yield point of the bent positions is improved. Therefore, cracking, creasing and rebounding of the bent positions of the pipe caused by incapability of completely plastically deforming due to non-uniform stress on the pipe are decreased.

Description

technical field [0001] The invention relates to the technical field of internal high pressure forming, and more specifically relates to an internal high pressure forming die. Background technique [0002] Internal high pressure forming, also called hydroforming or hydroforming, is a material forming process that uses liquid as a forming medium to achieve the purpose of forming hollow parts by controlling internal pressure and material flow. [0003] The principle of internal high pressure forming is to press the tube blank into the mold cavity through internal pressure and axial force feeding to form it into the required workpiece. For parts with a curved axis, it is necessary to pre-bend the tube blank into a shape close to the part, and then press to form it. [0004] At present, when using the above-mentioned internal high pressure forming process to manufacture pipe fittings, since the pipe fittings are basically curved or curved, and due to the different mechanical per...
