Problems solved by technology

[0005] Therefore, the purpose of the present invention is to provide a manufacturing and forming method of the tank top cover, to solve the problem that when the existing tank top cover mold proposed in the background technology is in the autoclave, the hot air circulation is not good, resulting in heat flow. Uneven distribution, poor thermal coupling conditions, and the performance of the workpiece produced by forming has certain inhomogeneity, which may cause the workpiece to fail to meet the design requirements; and the existing mold positioning is very inconvenient, for pendulums with anisotropic materials The positioning angle is not very accurate; the platform design is unreasonable and other problems that affect the speed of the experiment

Abstract

The invention provides a manufacturing and forming method for a top cover of a storage box. The manufacturing and forming method comprises the steps that a mold profile is obtained through finite element springback compensation according to a standard workpiece profile of the top cover of the storage box, and a top cover mold of the storage box is manufactured; then, a workpiece plate is placed on a mold profile panel, and the workpiece plate is completely wrapped with air felt; a sealant is pasted on the edge part of the end surface, and a vacuum bag is pasted on the sealant to enable the vacuum bag and the mold profile to jointly form a closed space; the closed space is vacuumized, so that the workpiece plate and the mold profile panel are close to be attached or are kept attached; the workpiece plate and the top cover mold of the storage box are put into an autoclave to be subjected to vacuum creep age forming, and the workpiece plate and the top cover mold of the storage box are separated after the process is completed; and the the allowance part is milled off to finish the manufacturing of the top cover of the storage box. According to the technical scheme, a series of problems of poor workpiece performance, inconvenient personnel operation, poor repeatability and the like caused by unreasonable mold design in the creep age forming process are solved.

Description

technical field [0001] The invention belongs to the preparation technology of advanced manufacturing, and in particular relates to a method for manufacturing and forming the top cover of a storage tank. Background technique [0002] Creep aging forming technology is a new forming technology that ingeniously combines the creep behavior of metals with aging strengthening behavior. Creep aging forming technology utilizes the creep deformation of metal materials under the joint action of artificial aging temperature and elastic stress. , to obtain a component with a certain shape, which has many advantages such as small damage, high forming accuracy, small residual stress, and good repeatability. With the continuous progress of our country's industry, our country's aerospace technology has developed rapidly, and the creep aging forming technology has continuously improved, and has become an indispensable large-scale panel forming technology in the field of aerospace product manu...
