Technology device for thin-wall double-layer structure heat correction

Abstract

The invention discloses a technology device for thin-wall double-layer structure heat correction. A base and a round support are connected through hexagon bolts. A boss at the lower end of a disc is arranged in a groove in the upper end of the round support, and the end face of the round support is in face contact with the two ends of the disc boss. A guide groove is formed in the upper end of thedisc, and an expansion block is placed in the guide groove. One end of each small stand column is provided with a thread and penetrates through the expansion block to be fixed in a threaded hole in the disc. One end of a big stand column is provided with a thread and penetrates through an installing hole of the disc to be inserted and connected in an installing hole of the round support and is fixed to the round support through a cylinder pin. A cone penetrates through the big stand column and makes contact with the disc, and the conical face of the cone makes contact with the conical face ofthe expansion block. For a component, the cone is used for tensioning the expansion block through the disc guide groove, a large wedge block tightly presses the cone through a big stand column hole,and meanwhile a small wedge block locks the expansion block through a hole of each small stand column. A flying ring is fixed to the big stand column. According to the technical scheme, the structureis reasonable, the operation requirements for component assembling, heat correction, detachment and the like are met, and the design drawing and machining requirements are finally met.

Description

technical field [0001] The invention relates to the technical field of aero-engine manufacturing, in particular to a process device for thermal correction of a thin-walled double-layer structure. Background technique [0002] At present, for thin-walled sheet metal welded structural parts, one is to use the tensioning method during the processing process, and the other is to use the traditional manual method in a free state to knock on the deformed part to ensure subsequent processing requirements. However, due to the limitation of the structure of this part, it cannot be effectively controlled by tensioning. At the same time, the material of the part is 0Cr17Ni4Cu4Nb, which is a martensitic precipitation hardening heat-resistant steel with strong strength. It is not easy to correct the deformation in the cold state, which brings difficulties to the subsequent processing of the part, which is to ensure the subsequent processing of the part. key issues.
