Problems solved by technology
[0005] In order to solve the problem in the existing technology that the quantitative stress aging test of wide plates cannot be carried out and the fixtures are simply pre-tightened with threads and then directly aged, which may cause deformation of the fixtures and samples after being exposed to high temperatures in the furnace, preloading The force on the thread may also weaken as the thread loosens, which cannot achieve the effect of quantitative research and other technical problems. The present invention provides a fixture for quantitative research on the stress aging of aluminum alloy wide plates, which is high temperature resistant, simple in structure, and Good looseness and easy to use

Abstract
The invention discloses a clamp for quantitatively researching stress aging of an aluminum alloy wide plate, and belongs to the technical field of aluminum alloy stress aging forming. The fixture for quantitatively researching the stress aging of the aluminum alloy wide plate comprises a base and a placement platform arranged above the base, the placement platform comprises a positioning block and a sliding block, grooves are formed in the tops of the positioning block and the sliding block, a sample piece is placed in the grooves in the tops of the positioning block and the sliding block, and the sliding block is in threaded connection with a main shaft. A guide rail is slidably arranged below the sliding block, and the sliding block is driven to move along the guide rail by rotating the main shaft, so that the sample piece is pulled. The clamp for quantitatively researching the stress aging of the aluminum alloy wide plate is resistant to high temperature, simple in structure, good in looseness resistance and convenient to use.
Description
technical field [0001] The invention relates to the technical field of aluminum alloy stress aging forming, in particular to a fixture for quantitatively studying the stress aging of aluminum alloy wide plates. Background technique [0002] Aging forming is a new aluminum alloy processing method, that is, to use the aluminum alloy sheet to undergo creep deformation at a certain temperature under stress, so as to obtain the desired shape. As an important forming method for integral panels, aging forming technology has unique advantages in the manufacture of aerospace devices and large aircraft integral panels. The plate after stress aging often has obvious anisotropy. In order to clarify the anisotropy of the plate after stress aging, the stress-strain curve of the uniaxial tension of the plate along different directions is often tested. The samples are all narrow samples, and the size in the width direction is not enough to take uniaxially stretched samples. In order to st...
