A new material tensile strength testing equipment

Abstract

The invention discloses a new material tensile strength testing device, which comprises a machine body casing. The top wall of the body casing is fixed with left and right symmetrical support blocks, tension beams are arranged between the support blocks, and tension beams are arranged inside the support blocks to A power device that moves up and down. The tension beam is fixed with a first fixed block that runs through the upper and lower surfaces of the tension beam. The first fixed block is provided with a first clamping cavity that runs through the upper and lower surfaces of the first fixed block. The first clamping cavity There is a first clamping block; the first clamping block and the second clamping block provided in the present invention cooperate with each other to detect materials with greater elasticity, and can shorten the stretching stroke, so that the height of the present invention is reduced and the occupied space is saved. Space, the third clamping block that is provided with under the action of the second limit chute and reverse tooth can close to each other tightly clamp the material with the downward movement of the stretched material to prevent the material from slipping.

Description

technical field [0001] The invention relates to the technical field of material strength detection, in particular to a new material tensile strength detection device. Background technique [0002] Tensile strength is the critical value of the transition of metal from uniform plastic deformation to local concentrated plastic deformation, and it is also the maximum bearing capacity of the material under static tensile conditions. Tensile strength is the resistance to the maximum uniform plastic deformation of the material. Before bearing the maximum tensile stress, the deformation is uniform and consistent, but after exceeding, the material begins to appear necking phenomenon, that is, concentrated deformation occurs. For brittle materials without uniform plastic deformation, it reflects the fracture resistance of the material, so when the material is produced , need to be tested. [0003] Existing tensile strength testing equipment will generate large vibrations when the mat...

AI Technical Summary

Problems solved by technology

[0003] Existing tensile strength testing equipment will generate large vibrations when the material to be tested breaks, which will cause damage to the precision parts in the equipment, and the existing tensile strength testing equipment will adapt to highly elastic materials in the future, and the tensile The strokes are designed to be very large, which makes the height of the equipment relatively high and occupies a large space, and the fixture is also easy to clamp the material, and can only measure the tensile strength of the material at room temperature, and the tensile strength at different temperatures cannot be measured. In the measurement, the flying debris was not intercepted when the measurement material was broken, and the debris easily entered some mechanisms and affected the operation of the mechanism
