Bending forming die for medium-thickness pore plate U-shaped part of asymmetric pore channel structure

Abstract

The invention discloses a bending forming die for a medium-thickness pore plate U-shaped part of an asymmetric pore channel structure. The bending forming die comprises a T-shaped force transmission part, a bending pressing head, a first rotatable supporting part, a second rotatable supporting part and a female die. A groove is formed in the female die. One end of the female die is connected withthe first rotatable supporting part. The other end of the female die is connected with the second rotatable supporting part. The first rotatable supporting part and the second rotatable supporting part are each provided with a downward slideway groove. The bending pressing head is installed at the lower end of the T-shaped force transmission part and matched with the groove. When the bending pressing head moves downwards to the groove through the T-shaped force transmission part via the downward slideway grooves, a medium-thickness pore plate to be bent is bent on one side, and therefore it isguaranteed that the overall bending deformation of the pore plate U-shaped part to be bent is small, bending cracking is avoided, and meanwhile a flow channel is not deformed.

Description

technical field [0001] The invention relates to the technical field of bending and forming processing of medium-thick plates, in particular to a bending-forming mold for U-shaped parts of medium-thick orifice plates with an asymmetric channel structure. Background technique [0002] Nuclear fusion is an inexhaustible, clean and safe new energy that has attracted much attention. The tritium-producing cladding is the key core component to achieve plasma containment, tritium value-added and energy extraction in fusion reactors. In the cladding structure, the first wall is the part outside the cladding that directly faces the plasma. In the plasma, it serves in harsh working conditions such as high temperature, high pressure, and irradiation. Its shape, material quality, and molding accuracy directly determine the Functional and safety properties of cladding. [0003] The overall outer shape of the first wall is U-shaped, and its interior contains multiple cooling flow channel...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing manufacturing process of the first wall is difficult to meet the requirements of the size of the flow channel and the outer wall at the same time. Therefore, a bending forming mold for thick orifice U-shaped parts in an asymmetric channel structure is provided to Ensure that the overall bending deformation is small and no bending cracks occur
