Starting rod forging is one of the most common key components in mechanical devices, and its dimensional accuracy control and detection is an important link to ensure its function and quality. This paper introduces the dimensional accuracy control and testing method of starting rod forging.
First of all, in the design stage, it is necessary to determine the design standards and drawing requirements of the starting rod forgings according to the specific requirements of use. These standards and requirements include a range of dimensional accuracy controls for starter bar forgings to ensure that they have the required functionality and performance during use.
In the forging process, reasonable process control is an important means to ensure the dimensional accuracy of the starting rod forging. First, you need to choose the right material to ensure that it has sufficient strength and toughness. Secondly, by means of preheating, forging process parameter control and die design, the starting rod forging can maintain a relatively stable size in the process of hot deformation. This requires professional forging technology and strict control of process parameters.
In the process of forging after forming, it is necessary to strictly control the processing technology to ensure the size control of the starting rod forging and the precision requirements after processing. Common processing techniques include grinding, turning and so on. When carrying out these processing operations, appropriate process measures need to be taken, such as controlling the grinding and cutting speed of the cutting tool, as well as controlling factors such as temperature and vibration during the processing to avoid affecting the dimensional accuracy.
Dimension detection is an important link to ensure that the dimensional accuracy of starting bar forging meets the requirements. Common dimensional measurement methods include coordinate measurement, micrometer or vernier caliper, comparable measurement and optical measurement.
Coordinate measurement is a method of measuring and analyzing three-dimensional geometric dimensions. The use of professional measuring instruments, such as coordinate measuring instrument, can accurately measure the key dimensions of the starting rod forging, and carry out data analysis and evaluation.
The common simple measuring tools such as micrometer or vernier caliper can directly measure the length, width and diameter of the forging of the starting rod, and the operation is simple and practical.
The comparable measurement method compares the dimensions to be measured with known dimensions or standard parts to determine whether the dimensions meet the requirements. This method is often used for some relatively simple starting rod forgings with obvious differences between sizes.
Optical measurement rules Measure and judge the curvature, flatness, etc. of the starter bar forgings by using optical equipment, such as microscopes, projectors, etc. This method is usually suitable for precision measurement of curved and special shape starter bar forgings.
Through the above dimensional accuracy control and detection method, it can effectively ensure that the dimensional accuracy of the starting rod forging meets the design requirements, so as to improve its performance and reliability. In actual production, it is necessary to select the corresponding method according to the specific situation, and strictly implement the relevant operations and standards to ensure the quality and reliability of the starting rod forging.
