The whole process of universal tension machine testing strong horse rope | Mechanical properties test of rope breaking tension elongation

Dali horse rope has the advantages of high strength and wear resistance, and is widely used in outdoor, fishery and hoisting industries. The breaking tension and tensile elongation of rope are the two core parameters to judge product quality and use safety. Chongqing Wanwei Instrument Laboratory actually filmed two groups of complete testing procedures for the tensile force of strong horse ropes, and showed you the standard testing procedures for the mechanical properties of professional ropes.

First, check the preliminary preparation and standardize the operation to ensure accurate tension data.
The test samples are two groups of strong horse ropes, and the whole test scheme is matched with the special winding tension fixture for ropes and used in conjunction with Chongqing Wanwei universal tension testing machine.
1. Install and fix the rope special fixture on the universal tensile machine, and debug the basic parameters such as equipment speed and measuring range according to the test standard;
2. Wrap the strong horse rope in the middle of the fixture to ensure the uniform stress of the rope and prevent the data of breaking tension and elongation from being greatly deviated due to unilateral stress;
3. Lock the clamp buckle and firmly fix the rope sample, so as to avoid rope slippage and position deviation from affecting the test results in the tensile test.

Second, uniform tensile test, real-time recording of rope deformation and ultimate tension.
After debugging the equipment parameters, set the industry standard tensile speed, and then start the universal tensile testing machine to stretch the sample at a uniform speed:
1. Real-time video recording the whole stretching process of the strong horse rope, so that the stress extension and deformation change of the rope are clearly visualized;
2. The equipment automatically collects mechanical data in real time, focusing on the two core indexes of rope breaking tension and tensile elongation;
3. The equipment continues to load the tension steadily until the strong horse rope is completely broken and the ultimate bearing stress state of the rope is completely restored.

Third, the test automatically generates a test report, and the original data can be traced back.
After the tensile test, Chongqing Wanwei Universal Tensile Testing Machine automatically integrates all the mechanical data collected in the whole process and outputs the standardized rope quality inspection report with one button. The report completely preserves all the original data, such as peak breaking tension, elongation curve and stretching time, which can provide authoritative and objective data support for rope manufacturers' ex-factory quality inspection, performance comparison of different types of ropes and product formula optimization.

summary
Standardized rope tension detection is the core process of controlling the safety performance of strong horse rope. The universal tensile testing machine of Chongqing Wanwei Instrument is selected, which can minimize the test error and truly restore the ultimate bearing capacity of the rope in cooperation with the standardized operation of fixture installation, centering winding and uniform tensile. Accurate detection data of rope breaking tension and elongation rate is not only a strong proof of the quality of rope products, but also an important guarantee for the safe use of ropes in outdoor, fishing, hoisting and other scenes.
