Description

Technical Field

[0001] The utility model relates to the technical field of strength detection of modified materials, in particular to a PA6 modified material strength detection device. Background Art

[0002] Nylon 6, also known as PA6, polyamide 6, and nylon 6, is a polymer compound. The chemical and physical properties of nylon 6 are very similar to those of nylon 66. However, its melting point is lower and the processing temperature range is very wide. Its impact resistance and dissolution resistance are better than nylon 66 plastic, but its hygroscopicity is also stronger. Because many quality characteristics of plastic parts are affected by hygroscopicity, this must be fully considered when designing products using nylon 6. In order to improve the mechanical properties of nylon 6, various modifiers are often added.

[0003] At present, the Chinese utility model with the announcement number: CN212568197U discloses a PA6 modified material strength detection device. This utility model discloses a PA6 modified material strength detection device, including a detection device body, the front side of the top of the detection device body is fixedly connected to a limiting device, the front and rear sides of both sides of the limiting device are provided with clamping blocks, and the opposite sides of the two clamping blocks are fixedly connected with sliding sleeves. By arranging the detection device body, limiting device, clamping block, sliding sleeve, sliding rod, fixed block, shell, fixing mechanism, fixed rod, support plate, tension spring, movable mechanism, knob, movable rod, limiting block, movable block, transmission rod, transmission block, movable hole, fixed hole, through hole, fixed groove, slide groove and slider for coordinated use, the problem of limiting the detected object in most existing strength detection equipment is solved. Most of them are directly placed on the limiting device. When the detection is carried out, the detected object is prone to offset, affecting the detection, causing unnecessary trouble to the user, and inconvenience to the user.

[0004] According to the above patent, although the existing PA6 modified material strength testing device can realize auxiliary positioning when performing strength testing on its PA6 modified material, thereby avoiding the easy displacement of the tested material and ensuring stability during testing, it requires the user to manually operate each structure to move and then position it when positioning the tested material, so as to complete the pressure positioning of the tested material. This not only wastes time but is also not conducive to user operation when used in actual testing operations. In addition, no buffering is performed when positioning the tested material, resulting in pressure loss, which indirectly affects the detection effect. Therefore, the above patent is improved based on the problems raised. Utility Model Content

Then, the buffer assembly at the bottom of the positioning plate contacts the top of the tested material, so that the buffer assembly retracts toward the positioning plate, so as to avoid pressure loss when the PA6 modified material is pressed and positioned, thereby ensuring the subsequent testing effect. Then, the positioning plate completes the positioning of the PA6 modified material with the cooperation of the buffer assembly. As a whole, there is no need for manual operation by the user, which saves time and effort and is more convenient for users to use. BRIEF DESCRIPTION OF THE DRAWINGS
