The dimensional accuracy control of copper forgings of agricultural machinery is mainly to ensure the assembly performance and working performance of forgings and other parts, and also to improve production efficiency and reduce quality loss. The following is the general dimensional accuracy control and measurement method:
- Design stage: In the design stage, it is necessary to determine the requirements of dimensional accuracy according to the function and use requirements of copper forgings, including dimensional tolerances, shape and position tolerances.
- Material selection: Select the appropriate copper alloy material, and ensure that the composition and performance of the material are stable. The selection of materials plays an important role in the control of dimensional accuracy.
- Forging process: reasonable forging process is used to control the dimensional accuracy of copper forgings. In the forging process, it is necessary to control the parameters such as pressure, temperature and speed of the forging to ensure that the dimensional accuracy of the forging meets the requirements.
- Processing technology: After forging is completed, a series of processing is required, such as turning, planing, milling, etc. These processes need to follow strict dimensional control requirements, and the use of appropriate measurement methods for dimensional inspection and correction.
- Measurement methods: The commonly used measurement methods for copper forgings are as follows:
- Combined measurement method: Comprehensive measurement using a variety of measuring tools, such as micrometers, vernier calipers, micrometers, etc., according to the overall and local size control requirements.
- Visual inspection method: The use of optical microscope or projector and other equipment to observe and measure copper forgings to determine whether the dimensional accuracy meets the requirements.
- Coordinate measurement method: The size of copper forgings is carefully measured by the coordinate measuring instrument, and the three-dimensional coordinate data of the size can be obtained, and the comparison and analysis are carried out.
- Image measurement method: The use of high-precision image measurement equipment to scan and measure copper forgings, can obtain holographic images and size data, and data analysis and comparison.
The above is a general introduction to the dimensional accuracy control and measurement methods of agricultural copper forgings, and the specific control requirements and measurement methods also need to be designed and selected in detail according to the actual situation.
