Tensile bending test equipment

Abstract

The invention provides tensile bending test equipment, and relates to the technical field of test equipment. The tensile bending test equipment comprises a support assembly, a clamping tensile assembly, a guide rail slide block assembly and a roller assembly; the rolling wheel assembly comprises a plurality of rolling wheels, and the rolling wheels are all arranged on a sliding block of the lead screw sliding block mechanism; the rolling wheels are sequentially arranged in the direction from a first chuck mechanism to a second chuck mechanism; and each rolling wheel can rotate around the axis of the rolling wheel. Acting force different from the stretching direction is applied to a test piece through the plurality of rolling wheels, and meanwhile, stretching force is applied to the test piece, so that the test piece is subjected to stretching bending deformation, and the test piece generates elongation far higher than that of a one-way stretching test in the prior art, so that the forming potential of a plate under the stretching bending condition is more truly reflected.

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...
