A plastic strength testing device

Abstract

The invention discloses a plastic strength detection device which comprises a detection box. A working cavity is provided in the detection box. A first passage is fixed on the left side of the detection box. A slidable threaded block is provided on the right side of the first passage. The upper side of the threaded block is provided with a clamping mechanism, and the upper side of the clamping mechanism is provided with a first sliding block capable of sliding left and right. The first sliding block is provided with a cross-sectional strength detection mechanism. There are two threaded support blocks, the upper ends of the two threaded support blocks are equipped with a circumference detection machine, and the feed pipes put into the detection box are clamped by the slider. The rubber clamping claws can change the circumference size, which is convenient for different sizes. The plastic pipe is clamped, and the circumferential strength of the plastic pipe can be checked by the circumference detection mechanism, and the outer wall of the pipe can be clamped by the air flow, and the circumference detection can be accurately performed.

Description

technical field [0001] The invention relates to the technical field of plastic strength detection, in particular to a plastic strength detection device. Background technique [0002] The strength of plastic products includes indicators such as punching strength, shearing strength, and tensile strength. Destructive tests are used to test these items. These indicators are all related to the toughness of the plastic material. For the same plastic, the better the toughness, the better the punching strength, shear strength, tensile strength and other properties. [0003] Plastic testing is to use various testing instruments to test and judge the mechanical properties, physical and chemical properties, electrical properties, thermal properties, combustion properties, weather resistance, and environmental performance of plastic products, raw materials, and additives. Among them, impact strength testing is a This is a very important indicator. The existing plastic impact strength t...

[0003] Plastic testing is to use various testing instruments to test and judge the mechanical properties, physical and chemical properties, electrical properties, thermal properties, combustion properties, weather resistance, and environmental performance of plastic products, raw materials, and additives. Among them, impact strength testing is a This is a very important indicator. The existing plastic impact strength testing device has the problem that it can only perform a single impact test, the test result is not perfect, and the shaking of the test device has a great influence on the test result, resulting in the problem that the test result is not accurate enough.
