Inflating thermal-expansion forming method for titanium alloy panel

Abstract

The invention discloses an inflating thermal-expansion forming method for a titanium alloy panel. A forming tool is of a group of upper and lower thermal forming dies with the same-sized notches, a gas inlet, a vent, two titanium alloy panel blank materials needing to be formed, a gas source, a gas source control cabinet, a high-temperature furnace and a detecting container are respectively arranged at the bottom of the forming cavity of the forming dies; the inflating quantization and visualization of an expansion process are realized, and the forming difference of parts is reduced.

Description

technical field [0001] The invention relates to the technical field of inflatable thermal expansion forming of titanium alloy plates, in particular to a method for forming parts by using a technical method of inflatable thermal expansion forming of titanium alloy plates in a state of thermal creep. technical background [0002] At present, the thermal creep forming method of titanium alloy usually adopts the method of coupling die forming, but in the forming process, the material loses its restraint due to the pressure flow, and when the coupling die does not reach the closed state, the surface of the material is covered with wrinkles, resulting in parts The phenomenon of serious dead wrinkles and scrapping occurs, which seriously restricts the quality of parts. In view of this, a new forming method must be found to replace the working mode of the coupled mold. [0003] The patent ZL200820005892.4 applied by the applicant in 2008 provides "a stamping device for hot creep fo...

Problems solved by technology

In actual use, this patented technology has the following disadvantages: 1. The air source is uncontrollable, and the inflation cannot be quantified only through simple valve control; 2. Only one part can be formed in each inflation forming process, and the production efficiency is low; 3. In the process of inflatable forming, it is difficult to control the forming process due to the lack of a detection device that reflects the degree of part forming

The above disadvantages have a negative impact on the mass production of parts. For example, because the inflation process cannot be quantified, each production can only rely on experience, and a unified standard cannot be formed. The parts produced in batches will have problems such as uneven wall thickness and large gaps between tires. Seriously affect the quality of batch production of parts
