Abstract

The invention provides a creep aging forming device for mechanically loaded aluminum alloy components, which includes a loading assembly, the loading assembly includes a loading rod, a loading connector, a worm, and a loading shaft, the loading shaft is arranged horizontally, and the loading rod includes two vertical shafts. Rods and cross bars, the loading connector includes an upper turbine ring and a lower connecting rod, the turbine ring is used to be sleeved on the loading shaft, each loading rod is at least connected with two of the same group The loading connectors are mated and connected, and each set of loading connectors is arranged in a misaligned axial direction of the loading shaft, and the worm and the turbine teeth on the top of the turbine ring are coordinated and adjusted so that the angles between the vertical rods of each loading rod and the horizontal plane are different. In the loading solution of the present invention, the angle between the loading rods can be adjusted according to the length of the aluminum alloy plate or the thickness of the plate, so that the force is more uniform and closely fits the mold surface. Compared with the prior art, aluminum alloy component products with higher precision can be prepared.

Description

technical field [0001] The invention belongs to the technical field of creep aging forming of large aluminum alloy components, and in particular relates to a creep aging forming device for large thin-walled aluminum alloy components used in aerospace. Background technique [0002] Creep aging forming is a new type of sheet metal forming technology, which can realize forming and strength improvement of components at the same time, and is widely used in the manufacture of large thin-walled components in aerospace. The creep aging forming process can be divided into three stages: loading stage, creep aging stage, and unloading stage. Among them, the bending loading methods of components mainly include mechanical loading and vacuum bag loading. The mechanical loading method requires two sets of concave and convex molds, but there are problems such as long heating time and large space volume, and is generally only suitable for small-scale components in the laboratory; the vacuum ...
