Description

Technical Field

[0001] The invention relates to the technical field of shaping devices, and in particular to a shaping device for superplastic forming of titanium alloy sheets and an operating method thereof. Background Art

[0002] During the bending process of the metal plate, the metal plate needs to be placed between the fixed die and the movable die, and then the movable die is pushed by the stamping mechanism to move toward the fixed die to deform the metal plate to complete the bending. After the bending is completed, in order to prevent the metal plate from rebounding due to elastic deformation, the fixed die and the movable die need to be kept in a closed state for a period of time to allow the bending part to be fixed. The fixing time varies depending on the material of the metal plate and other factors; the bending efficiency is low due to the long fixing time. The existing fixing device is generally a set of molds, matched with a set of telescopic cylinders, so the fixing device is generally provided with multiple sets. In this way, when the fixing time is long, the telescopic cylinders will be idle, which is relatively wasteful. Summary of the invention
