The dimension measurement and precision control of the forging die of construction machinery is a very important link, which is directly related to the quality and performance of the die manufacturing. The following is some content about mold size measurement and precision control:
Mold size measurement:
- Size measuring tools: commonly used measuring tools include micrometer, vernier caliper, outside micrometer, height gauge, etc. Select appropriate measuring tools according to different mold structure and size characteristics.
- Precision measuring instruments: Use optical projector, coordinate measuring machine and other precision measuring instruments to measure and analyze the mold size more accurately to ensure the accuracy of the mold size.
- Measurement methods: The commonly used measurement methods are direct measurement, contrast measurement, projection measurement, etc., according to the characteristics and requirements of the mold to choose the appropriate measurement method.
Precision control:
- Design accuracy: In the mold design, it is necessary to determine the design accuracy standard of the mold according to the actual application requirements and process conditions, and clearly communicate it to the mold processing personnel.
- Material selection: Select the appropriate mold material to ensure that it has sufficient strength and stability to meet the accuracy requirements in the process of mold processing and use.
- Processing process control: Adopt reasonable mold processing technology, including milling, grinding, EDM and other processes, strictly control the process parameters in the processing process to ensure that the accuracy is controlled within the specified range.
- Temperature control: During mold processing and use, attention should be paid to the influence of temperature on mold accuracy. Avoid dimensional deformation caused by temperature changes.
- Heat treatment control: Proper heat treatment of the mold to improve the hardness and stability of the mold.
- Inspection and correction: In the mold manufacturing process, carry out the necessary dimensional inspection and correction work, timely find and correct the size deviation, to ensure that the accuracy of the mold meets the requirements.
Through the strict management of the mold size measurement and precision control, the manufacturing quality and precision of the forging mold of construction machinery can be ensured to meet the design requirements, and the reliability and service life of the product can be improved.
