A tensile performance testing device based on polymer rubber testing

Abstract

The invention provides a tensile performance testing device based on polymer rubber testing, including a headgear, a pull-out rod, an insert frame, a pull-out frame and a positioning support plate; In the middle of the space between the slots, a double-shaft stepping motor is installed, and the left and right ends of the double-shaft stepping motor shaft are locked and connected with a gear; the first half of the two track grooves There is a row of scale marks on the outer wall of the installation frame; a proximity switch is installed in the middle of the top of the horizontal support plate of the installation frame by screw locking, and two positioning struts are also symmetrically supported on the inner end surface of the horizontal support plate. The right side support of the middle section of the track groove on the right side is equipped with a control electric box, the setting of the limit bar of the present invention, the S-type tension sensor is slid on the two positioning struts through four collars, and only the limit bar needs to be set. Loosen and remove the positioning rod, it can be quickly slid and removed for replacement and maintenance after damage.

Description

technical field [0001] The invention belongs to the technical field of tensile performance testing and supporting facilities for the production of polymer materials, and more specifically relates to a tensile performance testing device based on polymer rubber testing. Background technique [0002] Polymer rubber is used more and more widely, and the mechanical performance test closely related to it is particularly important. Such as the determination of mechanical properties of polymer rubber product inspection, evaluation and classification. Among them, the determination of the tensile properties of polymer rubber is particularly important. The tensile strength, tensile modulus and ultimate strain of the material can be measured through the tensile test. The material strength and elongation at break are related to calculation and design. The basis is also the basis for grading products [0003] Combining with the prior art, the present inventors found that although the ex...
