[0002] In the process of producing titanium alloy ring parts through casting process, the ring parts will be deformed during the wax mold pressing, shell preparation, casting finishing, defect repair and other processes. In order to meet the requirements of the dimensional accuracy of the ring parts, they need to be shaped. Usually, a graphite shaped tool is used for operation. The graphite shaped tool is usually an external structure. During operation, the ring parts need to be placed in the graphite shaped tool. At the same time, the ring parts and the graphite shaped tool need to be placed in a vacuum heat treatment furnace for shape treatment. Since the size outline of the graphite shaped tool is larger than the size outline of the ring parts, the space utilization rate of the vacuum heat treatment furnace is low. In addition, it is necessary to wait for the last shaping process to be completed before the graphite shaped tool can be used again for the next operation. Therefore, the use of graphite shaped tool is not conducive to large-scale production with cost reduction and efficiency improvement.
