Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] As shown in the figure, a thin plate material compression aid tool of the present invention includes a splint 1 and a fixing plate 2. A connecting plate 3 is provided between the splint 1 and the fixing plate 2, and a connecting plate 3 is provided between the splint 1 and the fixing plate 2. There is a pressing plate 4, and the fixing plate 2 is provided with a fastening bolt 5 for pressing the pressing plate 4 against the clamping plate 1, and a pressing head 7 for pressing the test sample 6 is arranged between the pressing plate 4 and the clamping plate 1. Place the test sample 6 and the indenter 7 between the clamping plate 1 and the pressure plate 4, rotate the fastening bolt 5, fix the test sample 6 and the indenter 7, and press the test sample 6 through the indenter 7 to complete the test.

[0014] In this embodiment, a plurality...

Abstract

The invention relates to an auxiliary compression tool for a thin plate material and an application method thereof. The auxiliary compression tool comprises a clamping plate and a fixed plate, wherein the clamping plate is connected with the fixed plate; a pressing plate is arranged between the clamping plate and the fixed plate; the fixed plate is provided with a fastening bolt for pressing the clamping plate by using the pressing plate; a pressing head for extruding a testing sample is arranged between the pressing plate and the clamping plate; the testing sample is placed between the clamping plate and the pressing plate and the pressing head is placed above the testing sample; the fastening bolt is adjusted and the pressing plate is uniformly squeezed through a resilient sheet to clamp the testing sample; finally, a test is finished through squeezing the testing sample through the pressing head. According to the auxiliary compression tool disclosed by the invention, the pressing amount of sheet material compression is improved, a traditional sheet material compression test head is prevented from being bent and losing the stability, and the stability of the sheet material compression is reduced; the size requirement of the sheet material compression testing sample enables the sheet material compression to be convenient and simple, so that a thin sheet material can be subjected to the stable compression test and is not bent to lose the stability, and the precision and the efficiency are improved.

Description

Technical field [0001] The invention relates to the field of physical property testing, in particular to a thin plate material compression auxiliary tool and a use method. Background technique [0002] Generally speaking, stretching and compression are the most basic ways of receiving force during plastic deformation, and they are widely studied as basic experiments in plastic deformation. The compression experiment on the material is mainly carried out with the bar as the main body. However, due to the difference in the stress state during the processing of the plate, the plate and the bar exhibit different properties, so for the compression deformation of the relevant plate, the bar The compression test based on the material is not enough to accurately explain the problem. Especially for the thin plate compression test, it is particularly important in the research of numerical simulation. However, it is difficult to test due to the compression and bending instability, and the ...
