What is an elongation testing machine?
In the fields of industrial production, materials research and quality control, the elongation testing machine is an important testing equipment used to measure the elongation properties of materials during the stretching process. With the rapid development of materials science, elongation testing machines have become more and more widely used and have become an indispensable testing tool in many industries. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the elongation testing machine.
1. Definition of elongation testing machine
Elongation testing machine, also known as tensile testing machine or material testing machine, is a device used to test the elongation, tensile strength, breaking strength and other mechanical properties of materials under the action of tensile force. It assesses a material's ductility and mechanical properties by applying a controlled tensile force and measuring its deformation.
2. Working principle of elongation testing machine
The working principle of the elongation testing machine is based on the basic principles of mechanical testing. The equipment fixes the material sample through a clamp, and then applies tensile force through a motor or hydraulic system, while measuring force and deformation data in real time through sensors. This data is transferred to a computer or control system and processed to generate a test report.
| components | Function description |
|---|---|
| fixture | Fix the sample to ensure that it does not slip during the test |
| force sensor | Measure the applied tensile force |
| Displacement sensor | Measure the elongation of the sample |
| control system | Control the testing process, record and analyze data |
3. Application fields of elongation testing machine
Elongation testing machines are widely used in many industries. The following are its main application areas:
| Industry | Application scenarios |
|---|---|
| metal material | Test the elongation and tensile strength of metal sheets and wires |
| Plastics and Rubber | Evaluate the ductility and toughness of plastic films and rubber products |
| Textiles | Measure the tensile properties of fibers and fabrics |
| building materials | Test the mechanical properties of steel bars, concrete and other materials |
4. Technical parameters of elongation testing machine
The performance of an elongation testing machine is usually described by the following technical parameters:
| parameters | Description |
|---|---|
| maximum load | The maximum tensile force that the equipment can exert, usually in kN |
| Test speed | Stretch speed range, usually 1-500mm/min |
| Accuracy | Accuracy of force and displacement measurements, typically ±0.5% |
| itinerary | Maximum moving distance of the fixture |
5. Suggestions for purchasing elongation testing machines
