What is a manual spring testing machine?
In the fields of industrial production, quality inspection and scientific research, spring performance testing is crucial. As a common testing equipment, the manual spring testing machine is widely used to test the compression, tension, stiffness and other properties of springs. This article will introduce in detail the definition, working principle, application scenarios and comparison of popular models on the market of manual spring testing machines to help readers fully understand this equipment.
1. Definition of manual spring testing machine
The manual spring testing machine is a device that tests the mechanical properties of springs through manual operation. It is mainly used to measure the elastic coefficient, maximum load, deformation and other parameters of the spring to ensure that the spring meets the design and use requirements. Compared with electric or hydraulic testing machines, manual spring testing machines have a simple structure and easy operation, and are suitable for use by small and medium-sized enterprises and laboratories.
2. Working principle of manual spring testing machine
The manual spring testing machine applies force by manually rotating a handle or lever to cause compression or tensile deformation of the spring. The equipment is equipped with high-precision sensors and instruments to measure force and displacement in real time, and output test results through a mechanical or digital display system. Its core components include:
| Part name | Function |
|---|---|
| loading mechanism | Apply force by manual operation |
| force sensor | Measure the force on the spring |
| Displacement sensor | Record spring deformation |
| Display instrument | Display test data in real time |
3. Application scenarios of manual spring testing machine
Manual spring testing machines are suitable for a variety of industries and scenarios, including:
| Industry | Application Notes |
|---|---|
| automobile manufacturing | Test suspension springs, clutch springs, etc. |
| Electronic appliances | Detect button spring and battery contact spring |
| Machinery manufacturing | Verification of elastic elements in mechanical devices |
| Scientific research and education | For mechanical experiments and teaching demonstrations |
4. Comparison of popular models of manual spring testing machines
Based on market research in the past 10 days, the following is a parameter comparison of several popular manual spring testing machines:
| Model | maximum load | Accuracy | price range | brand |
|---|---|---|---|---|
| MT-100 | 1000N | ±1% | 2000-3000 yuan | Company A |
| HS-200 | 2000N | ±0.5% | 3500-4500 yuan | Company B |
| JM-500 | 5000N | ±0.2% | 6000-8000 yuan | C company |
5. Advantages and Disadvantages of Manual Spring Testing Machine
Although the manual spring testing machine is simple to operate, it also has its limitations. Here are its main pros and cons:
| Advantages | Disadvantages |
|---|---|
| Simple structure and low maintenance cost | Testing efficiency is low |
| Low price, suitable for businesses with limited budget | Relying on manual operations, data consistency may be affected |
| Highly portable and suitable for on-site testing | Not suitable for super load testing |
6. How to choose a manual spring testing machine
When choosing a manual spring testing machine, consider the following factors:
1.Testing requirements:Select the model based on the maximum load and accuracy requirements of the spring.
2.budget: Manual testing machines are less expensive, but need to balance performance and cost.
3.Brand and service: Prioritize reputable brands to ensure after-sales support.
4.Extended functions: Some devices support data export or software analysis, suitable for advanced users.
Conclusion
The manual spring testing machine is an important tool for spring testing, especially suitable for small and medium-sized enterprises and laboratories. Through the introduction of this article, readers can fully understand its working principle, application scenarios and key points of selection, providing a reference for actual purchase and use.
