Abstract

The invention provides a tensile bending test equipment, which relates to the technical field of testing equipment. The tensile bending test equipment includes a bracket assembly, a clamping tensile assembly, a guide rail slider assembly, and a roller assembly; the roller assembly includes a plurality of rollers, multiple Each of the rollers is arranged on the slider of the screw slider mechanism; along the direction from the first chuck mechanism to the second chuck mechanism, a plurality of the rollers are arranged in sequence; and each Each of the rollers can rotate around the axis of the roller. A force different from the stretching direction is applied to the test piece by multiple rollers, and a tensile force is applied to the test piece at the same time, so that the test piece is stretched and bent, so that the test piece is much higher than the unidirectional in the prior art. The elongation of the tensile test to more truly reflect the forming potential of the sheet under tension bending conditions.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a tensile bending testing equipment. Background technique [0002] Tensile testing machine is the main tool used to test the mechanical properties of materials. The tensile testing machine can carry out unidirectional tensile test on the material, which is easy to operate and can fully provide information on the plastic flow of the material. [0003] However, uniaxial tensile testing is limited by the phenomenon of necking, the non-uniform deformation of the gauge region, which causes the material to fail in a localized area. From the study of tensile testing of materials, we can recognize that materials are actually capable of greater strains near the full gauge length. However, due to the localized deformation, the remaining material of the test section was still "understretched", ie the section was not fully stretched. [0004] It can be seen that the test data ob...
