Aluminum alloy creep aging forming equipment

Abstract

The invention discloses aluminum alloy creep aging forming equipment which comprises a fixing mechanism, a mold mechanism and an adjusting mechanism. The mold mechanism is located in the fixing mechanism, and the adjusting mechanism is located on the top of the fixing mechanism. The fixing mechanism comprises a bottom box, the two ends of the bottom box are rotationally connected with first lead screws correspondingly, and the outer walls of the first lead screws are in threaded connection with first sliding blocks; according to the device, aluminum alloys with different widths can be supported and fixed, irreversible deformation of areas, not needing to be subjected to creep forming, of the aluminum alloys is prevented under the conditions of long-time gravity and heating during temperature rise creep deformation, and under the action of a pressing plate and a driving box, the deformation of the areas does not need to be subjected to creep forming. The outer surface of the aluminum alloy plate in the width direction and the length direction can be fixed, so that in the loading process of the aluminum alloy plate, the phenomenon that the loading deformation of the aluminum alloy plate is different from an expected curved surface due to infirm fixation in the width direction and the length direction is prevented.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing. Specifically, it is an aluminum alloy creep aging forming equipment. Background technique [0002] Creep is a phenomenon in which the strain of a solid material increases with time while keeping the stress constant. It is different from plastic deformation. Plastic deformation usually occurs after the stress exceeds the elastic limit. As long as the stress acts for a long time, creep can also occur when the stress is less than the force applied by the elastic limit. Many materials (such as metals, plastics, etc.) , rock and ice) all exhibit the property of creep under certain conditions. [0003] Chinese patent document CN 112338053 A discloses a large-scale aluminum alloy component creep aging forming device, the device includes a loading assembly, the loading assembly includes a loading rod, a loading connector, a fixed pin and a loading shaft, and the device passes through ...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned patents, when loading aluminum alloys, it is impossible to fix aluminum alloys of different lengths and widths, and it is not convenient to creep a certain area of ​​aluminum alloys with different lengths, widths, and thicknesses, causing great limitations. And for the aluminum alloy boards with different length and width specifications, the full board surface support cannot be realized, resulting in the occurrence of areas where the aluminum alloy does not need to undergo creep deformation under the condition of gravity and heating for a long time during heating and creeping. Irreversible deformation, and after the aluminum alloy heats up and creeps, automatic loading and unloading cannot be realized, and it is not easy to load and unload, and secondary deformation of the aluminum alloy is prone to occur, and the high temperature of the aluminum alloy is easy to cause harm to people, so there are still great restrictions
