The dimensional accuracy control of ring forging refers to the control and guarantee of the size of the parts in the process of ring forging to ensure the dimensional accuracy of the parts to meet the design requirements. In order to achieve dimensional accuracy control, it is necessary to control and optimize from the aspects of material selection, mold design, heating temperature, hammering force, etc.
In the ring forging process, there are several common dimensional accuracy measurement methods:
- Snap gauge measurement: Use the snap gauge to directly measure the outer diameter, inner diameter or other key dimensions of the part for dimensional inspection. Calipers require high accuracy and reliability, and the right type and size need to be selected according to the shape and requirements of the part.
- Three-block floating head measurement: The measurement method uses fixed block, adjusting block and floating block to measure according to the geometric shape characteristics of the forging. The dimensional accuracy of the part is determined by measuring the distance or clearance of these three measuring points.
- Image measurement: The use of optical lenses or high-speed camera technology to observe and measure parts. More accurate dimensional data can be obtained through image processing software. This method is suitable for the measurement of parts with complex shape and high dimensional accuracy.
4.CMM (Coordinate Measuring Machine) measurement: use the coordinate measuring machine to measure the forgings, and obtain the three-dimensional coordinate data of the parts through the probe and measurement software. This method is suitable for ring forgings with complex shape, high size requirement and many geometric features.
In addition to the above measurement methods, other dimensional detection methods such as laser scanning and projection measurement can also be used according to the specific situation. In actual operation, the appropriate size measurement method should be selected according to the shape and size requirements of the ring forging and the production situation, and the accuracy and reliability of the measuring equipment should be ensured to ensure the dimensional accuracy control of the parts and meet the quality requirements.
