1. Definition of steel bar tensile machine
The steel bar tensile machine is a kind of testing equipment specially used to test the mechanical properties of steel bars and other metal materials. By applying tensile force, it measures the deformation and fracture of steel bars during the stretching process to evaluate key parameters such as tensile strength and elongation.
2. Working principle of steel bar tensile machine
The working principle of the steel bar tensile machine mainly includes the following steps:
1.Clamp the specimen: Fix the steel bar specimen in the upper and lower clamps of the tensile machine to ensure firm clamping.
2.Apply tension: Applying gradually increasing tensile force to the steel bars through a hydraulic or motor drive system.
3.Data collection: The sensor collects tension, deformation and other data in real time and transmits it to the control system.
4.Result analysis: The system automatically generates the tension-deformation curve and calculates tensile strength, yield strength and other parameters.
3. Application scenarios of steel bar tensile machines
Steel bar tensile machines are widely used in the following fields:
1.construction project: Test whether steel bars meet national standards to ensure project quality.
