What is a coil tensile testing machine?
In industrial production, the coil tensile testing machine is a common testing equipment, mainly used to measure the tensile strength, elongation at break and other mechanical properties of coils (such as metal, plastic, paper, etc.). With the rapid development of materials science, coil tensile testing machines play an important role in quality control, research and development, and standardized testing. This article will introduce in detail the definition, working principle, application fields and recent hot topics of the coil tensile testing machine.
1. Definition of coil tensile testing machine
The coil tensile testing machine is a device specially used to test the mechanical properties of coil materials. It applies tensile force and measures the deformation and fracture of the material during the stress process to evaluate the strength, toughness and durability of the material. This equipment is widely used in manufacturing, scientific research institutions and quality inspection departments.
2. Working principle of coil tensile testing machine
The working principle of the coil tensile testing machine is based on the basic principles of mechanical testing. The equipment fixes both ends of the coiled material through clamps, then applies tension through a motor or hydraulic system, and records the relationship between tension and deformation. Test data can be displayed and stored in real time to facilitate subsequent analysis.
| Test parameters | Description |
|---|---|
| Maximum pulling force | The maximum pulling force that the device can exert, usually in Newtons (N) or Kilonewtons (kN). |
| Test speed | The speed at which tension is applied is usually adjustable in millimeters per minute (mm/min). |
| Accuracy | The measurement accuracy of the equipment is usually ±0.5% or higher. |
3. Application fields of coil tensile testing machine
Coil tensile testing machines are widely used in many industries. Here are some of the main application areas:
| Industry | Application scenarios |
|---|---|
| metal processing | Test the tensile strength, yield strength, etc. of metal coils. |
| plastic manufacturing | Evaluate the mechanical properties of plastic films and packaging materials. |
| paper production | Measure the tensile strength and elongation at break of paper. |
| automobile manufacturing | Testing the durability of automotive roll materials. |
4. Recent hot topics
