Abstract

A material bending performance testing device comprises a base, a supporting plate, a mounting frame, a plurality of supporting rods, a positioning piece, a power device, a telescopic rod and a pressing head. The supporting plate is arranged at the rear end of the base, and scale values are arranged on the front end face of the supporting plate in the vertical direction and located on the verticalcenter line of the supporting plate. The mounting frame is arranged at the top of the supporting plate; the power device is arranged on the mounting frame and is in power transmission connection withthe upper end of the telescopic rod, and the telescopic rod is arranged along the vertical center line of the supporting plate; the pressure head is arranged at the bottom of the telescopic rod; twogroups of supporting rods are arranged, and each group comprises two supporting rods; and the vertical center lines of the two sets of supporting rod supporting plates serve as the symmetry axis and are arranged at the two ends of the base correspondingly. The supporting rod is provided with a plurality of limiting rods; connecting rods are arranged at two ends of the positioning piece; placing holes are formed in the middles of the positioning pieces. According to the invention, the deformation quantity of the workpiece can be conveniently controlled and metered, the final bending condition of the workpiece can be determined, the material performance can be judged, and the workpiece fracture critical value can be measured.

Description

technical field [0001] The invention relates to the field of testing devices, in particular to a material bending performance testing device. Background technique [0002] With the development of society, various new materials gradually occupy the existing market and impact the market. New materials should be tested for their physical and chemical properties before use; in physical testing, the bending performance test of materials is very important. [0003] Existing material bending performance tests are often only tested for the maximum bending stress state of the material, but there is no good measurement of the deformation of the material after bending and the automatic recovery state of the material after the force is removed. [0004] Therefore, how to test the deformation of the material and automatically restore the state in the laboratory or teaching process is a problem that needs to be solved. Contents of the invention [0005] (1) Purpose of the invention ...
