[0002] In double fork forging production process, the forging die for double fork forging is composed of upper die and lower die, due to the unevenness of metal horizontal deformation resistance, equipment guiding accuracy, forging thickness size fluctuation and die machining accuracy and other factors, the upper die and the lower die will have horizontal relative position error when forging double fork combined die, so that the upper die profile of double fork forging and the lower die profile will have relative deviation, and this deviation is called misregistration. If misregistration exceeds the specified range, the forging will be scrapped or the quality of the subsequent process will be affected, so misregistration is an important quality indicator of die forging, which must be detected in the production process to prevent product quality problems.

[0003] At present, the detection of double fork forging misregistration is carried out on the test platform by determining the reference line of the forging, detecting and determining the misregistration of double fork, and also considering the influence of thickness size factor, which is very low in efficiency and is not conducive to the rapid and effective process monitoring.
