The precision measurement of the forging die of construction machinery is one of the important quality control links. Mold accuracy measurement is mainly evaluated through the following indicators:
- Dimensional accuracy: including the measurement of the length, width, height and other dimensions of the mold, usually using special measuring tools, such as calipers, vernier calipers or coordinate measuring instruments. The deviation of these dimensions will directly affect the working performance and assembly quality of the mold.
- Flatness and verticality: Flatness refers to the degree of deviation between the mold surface and the reference plane, and verticality refers to the degree of deviation between the mold surface and the reference vertical line. These indicators can be measured with equipment such as parallel planeters and projectors.
- Mold aperture accuracy: the size of the aperture in the mold is crucial to the machining accuracy of the workpiece. The aperture can be measured using tools such as micrometers and inner calipers and compared to the design requirements.
- Surface quality: The surface quality of the mold directly affects the surface quality of the workpiece. The surface of the mold can be observed and evaluated using optical microscopes, scanning electron microscopes and other equipment to determine whether there are defects, wear or other undesirable conditions.
Error analysis is a comprehensive evaluation and analysis of the measurement results of mold accuracy to determine the possible error sources and improvement directions. Common sources of error include material properties, processing technology, measuring tools and so on. In the process of error analysis, statistical methods can be used to process the data, extract key indicators, and compare with national standards or related technical specifications, so as to draw conclusions and put forward suggestions for improvement.
In short, mold accuracy measurement and error analysis is an important link to ensure the quality of construction machinery forging die, through accurate measurement and analysis, problems can be found in time and take appropriate measures to improve the production quality and efficiency of the mold.
