Description

Technical Field

[0001] This utility model belongs to the field of forging technology, and in particular relates to a mandrel guiding device based on the processing of large-size forgings. Background Technology

[0002] For forging large workpieces, depending on the characteristics of the workpiece, integral rod structures such as elongated mandrels, punch mandrels, or mandrels supported at the workpiece's axial center are required. Currently, robotic arms / mechanical grippers are used to hold the mandrel to ensure it is positioned between the die and the forging hammer. However, due to the large size of the workpiece, the corresponding mandrel specifications and total weight are also large. Using a mechanical gripper alone will result in insufficient stability. If it deviates or falls off, it will cause a safety accident. At the same time, if the accuracy deviation is too large, it will not only affect the normal forging work, but also affect the subsequent precision turning operations, affecting product quality and work efficiency.
