Description

technical field [0001] The invention belongs to the field of auto parts processing, in particular to an on-line temperature detection device and method for hot forging of auto parts. Background technique [0002] Initial forging temperature and mold temperature rise are very important process parameters in forging production, especially aluminum alloy forging, which directly affect the stability of the metallographic structure of the product. When the temperature is too high, it is easy to form coarse-grained ring structure defects. The crystal ring is directly judged as a waste product, and the temperature is too low, which will affect the fluidity of the metal and cause the forging to be unable to be filled. Therefore, it is very important to monitor the temperature. The traditional temperature monitoring equipment can only count the temperature data at a single point. Statistics, storage and recording points are at the monitoring point, and the conventional traditional mo...

[0002] Initial forging temperature and mold temperature rise are very important process parameters in forging production, especially aluminum alloy forging, which directly affect the stability of the metallographic structure of the product. When the temperature is too high, it is easy to form coarse-grained ring structure defects. The crystal ring is directly judged as a waste product, and the temperature is too low, which will affect the fluidity of the metal and cause the forging to be unable to be filled. Therefore, it is very important to monitor the temperature. The traditional temperature monitoring equipment can only count the temperature data at a single point. Statistics, storage and recording points are at the monitoring point, and the conventional traditional monitoring method is to monitor the temperature at the exit position of the intermediate frequency furnace, and there is a gap between this position point and the initial forging time, and the initial forging temperature cannot be accurately obtained, which directly affects the temperature control of the product. Accuracy, and the process temperature is only displayed at the temperature measurement point, and the storage record and statistical analysis functions are not realized, which is not conducive to the control of the process by craftsmen and production control personnel
