Abstract

The invention discloses a pressure loading device for testing stress corrosion performance of a material, which comprises a bottom plate, a buffer structure for preventing the material from being directly damaged, a clamping structure for preventing the material from deviating and an adjusting structure for accelerating the working efficiency, and is characterized in that a vertical column is mounted at one end of the top end of the bottom plate; a supporting plate is arranged above the bottom plate at one end of the stand column, the buffering structure is arranged between the supporting plate and the bottom plate, a containing plate is installed in the center of the top end of the supporting plate, the clamping structures are arranged in the supporting plate on the two sides of the containing plate, and a top plate is installed at the top end of the stand column. A driving motor is mounted in the center of the top end of the top plate. By rotating the adjusting rod, under the cooperation of threads of the supporting plate, the sliding plate can slide in the limiting groove, the clamping plates are driven to move until the two clamping plates clamp materials, and the structure is beneficial to improving the applicability of the device.

Description

technical field [0001] The invention relates to the technical field of pressure loading, in particular to a pressure loading device for stress corrosion performance testing of materials. Background technique [0002] After all kinds of materials are processed and produced, they need to be tested in various performance aspects, so as to detect whether the materials meet the standards and ensure whether the quality is qualified, and the stress corrosion performance test is one of them, which requires the use of To the pressure loading device, and the existing pressure loading device still has many deficiencies. [0003] First, the traditional pressure loading device does not have the function of multi-angle pressure testing, and can only perform pressure loading on the local position of the material, resulting in poor applicability of the device; [0004] Second, the traditional pressure loading device cannot quickly fix the material, resulting in the material being prone to ...
