The tensile testing machine is also called the electronic tensile testing machine. It is used to test the tensile strength of materials. Everyone knows this well. Debugging by the manufacturer, you can also master some maintenance methods to debug it yourself.
First of all, we need to know why the data of the tensile testing machine is inaccurate. There are many reasons for this. The electronic tensile test requires the workpiece to work at the yield point. In this environment, it is easy for the workpiece to plastically deform, Fracture, which will cause inaccurate data of the electronic testing machine.
主要原因 The main reasons for inaccuracy are:
1. The chuck may be loose, which is usually caused by sudden break.
2. The problem of the circuit is mainly caused by plastic deformation, because plastic deformation may cause some overload of the circuit, cause the capacitor to be broken down, and affect the test data.
Maintenance methods are divided into: test repair, minor repair, overhaul. Test repairs are performed once a week. The test repairs are mainly tests. The test method is: test a previous workpiece, remove the test error of the previous test, and then see how much the error is, and perform easy loosening and locking. Then test to minimize the error as much as possible. Minor repair: maintenance, that is, testing and testing of various parts of the equipment, cleaning up foreign objects in various places, and measuring in preparation for the next major repair. Overhaul: It is based on close observation and minor repair measurement to replace or repair parts with large wear.
(2) The equipment must be carefully repaired and maintained. Only when the equipment is properly maintained, it will not affect the use at critical moments and save the maintenance costs.
