The invention belongs to the field of deep-drawing in thermoforming, particularly relates to a method and a device for thermal deep-drawing of titanium alloy spindle parts, and aims to overcome the shortcomings of wrinkle, cracking and the like of an existing thermal deep-drawing process method. Narrow adjusting range of blank holding force is avoided. The thermal deep-drawing method includes the steps: cutting blanks according to the curve shape of a material inlet; clamping a reverse redrawing die into a worktable of a thermal deep-drawing press; performing reversible deformation deep-drawing and controlling forming stroke to reach five eighths of the whole depth; clamping a deep-drawing die into the worktable of the thermal deep-drawing press; performing deep-drawing deformation, and maintaining pressure when the forming stroke reaches the closed state of a punch and a die; opening the die and taking out the parts, cooling the parts to reach indoor temperature, cutting the parts and machining the parts. The device for implementing the thermal deep-drawing method comprises the reverse redrawing die and the deep-drawing die. A tool is simple in structure and convenient to operate and use, mass production cost is reduced, and production efficiency is improved.
Description
technical field [0001] The invention belongs to the field of deep drawing in hot forming, in particular to a method and device for hot drawing of a titanium alloy shuttle. Background technique [0002] At present, in the thermoforming process, for special-shaped thin plate structural parts, deep drawing forming or stamping without blank holder is generally adopted. However, the wool of deep-drawn parts is usually in a regular shape such as a rectangle or a circle, and it is difficult to carry out accurate drawing of curved surface structural parts. Because of the implementation of the flat wrinkle function of the blank holder ring, the distribution of the blank holder force on the edge tends to be uniform; especially in the design of special-shaped thin plate structural parts, it is difficult to effectively calculate the blank holder force and punching force, and improper proportioning may easily cause forming defects in parts. For blank holder The regulation of force requi...
