Quality inspection and evaluation method of agricultural machinery forgings

The quality inspection and evaluation method of agricultural machinery forgings mainly includes the following aspects: Appearance inspection: Appearance inspection is to check the shape, size, finish and defect of the surface of agricultural machinery forgings. The appearance of agricultural machinery forgings is evaluated and judged by means of visual inspection, microscopy and testing instruments. Size detection: Size detection is to measure the various size parameters of agricultural machinery forgings and compare them with the design requirements. Commonly used tools are calipers, vernier calipers, gauges, etc., can measure the plane size, diameter, length and other parameters through the gauge. Material composition analysis: The material composition of agricultural machinery forgings has an important impact on its performance and quality. Through chemical analysis methods, such as spark spectroscopy, spectral analyzer, etc., the content of various elements in agricultural machinery forgings can be detected, and compared with the standard requirements. Physical performance test: Physical performance test is to determine the mechanical properties of agricultural machinery forgings, including tensile strength, yield strength, hardness and other indicators. Through universal testing machine, impact testing machine, hardness tester and other equipment to test, evaluate the physical properties and strength of agricultural machinery forgings. Process performance test: Process performance test is to evaluate the machining performance of agricultural machinery forgings, including heat treatment performance, weldability, machinability, etc. Through heat treatment test, welding test, cutting test and other means, the performance of agricultural machinery forgings under different technological conditions is tested. Life assessment: Life assessment is to predict and evaluate the service life of agricultural machinery forgings. Fatigue test, corrosion resistance test and other methods are used to simulate the working conditions of agricultural machinery forgings in actual use, and make life prediction and evaluation. The above is the general method of quality detection and evaluation of agricultural machinery forgings, and the appropriate detection means and equipment can be selected according to the specific situation for evaluation. At the same time, in the actual operation process, it is necessary to comply with the relevant standards and norms to ensure the accuracy and reliability of the evaluation results.
