A spring testing machine is an instrument that specializes in testing springs. After the spring is produced, before use, it must pass a strict test before it can be put into use, because most of the springs are used in machinery, the main components of the vehicle, such as the spring on the vehicle, if the spring installed on the car has not undergone strict testing, and the performance does not meet the requirements, it is easy to cause very serious consequences; Another example is the spring used for shock absorption, because of the decline of performance, the vehicle loses its balance, which is easy to cause traffic accidents. So, what are the structure of the spring testing machine and the daily maintenance of the testing machine?
First, the structure of the spring testing machine
1. The single-arm spring testing machine is mainly used for conventional single tension and compression, which is generally a digital display box to display the test results, and can also be upgraded to be equipped with a computer LCD screen display, equipped with a printer, which can print the test results, which is cheaper than the other two structures.
2. The portal spring testing machine can carry out a series of tests such as tensile, compression, shear, bending and so on on various materials, the upper structure of the machine is tensile and the lower structure is compressed, bent and shear test, which is usually computer-controlled, liquid crystal display, printer, and the test results are more accurate and comprehensive than the digital display box, which is slightly more expensive than a single arm.
3. The floor-mounted spring testing machine is similar to the portal spring testing machine for material testing, with high rigidity structure, large test space, high stability, computer control, LCD screen, and manual control button box! The operation is more user-friendly and flexible. ** is the more expensive of the three. The floor-mounted type is also divided into two types: domestic configuration and imported configuration, which can meet the different requirements of customers, with higher accuracy and more accurate test force value than imported configuration. **Also a little more expensive than domestic. Customers can choose the right model according to their own needs.
2. Daily maintenance of spring testing machine
1. Under normal operating conditions, the validity period of the spring testing machine for one time of value error verification is one year.
2. When the spring testing machine is operated and used, especially when the load is discharged, it should not be let go suddenly, so as not to produce violent vibration and affect the accuracy of the spring testing machine.
3. Regarding the lifting rack and pressure filling cup of the spring testing machine, smooth oil should be added frequently.
4. The spring testing machine should be covered with a dust cover at the end of operation to avoid dust falling into the machine.
5. In order to maintain personal safety, the spring testing machine should be properly grounded.
6. When reviewing the experiment, preheat the machine for 20 30min, with 0The 3-level standard dynamometer calibrates the accuracy adjustable gain adjustment knob of the spring testing machine so that the error is 1%.
