钛合金在飞机上的应用日益广泛。但是钛合金室温下塑性变形范围小、回弹量大、缺口敏感性高,多数情况下需在热状态下成形。因此探求热状态下钛板的成形性能和成形模具的结构,是能否经济地、大批量地应用钛合金材料的关键。我厂的生产实践表明,在合适的温度、时间和压力规范内,只要模具合理,就能获得质量稳定的零件,基本上不再需要随后的手工整修。一、钛板零件的成形某机上共有21种钛合金零件,材料牌号为TA2、TC1,料厚在0.5～1毫米。根据零件的形状,按照操作的难易,将钛板零件的成形方案分类如表1。
Titanium alloy is widely used in the aircraft. However, the plastic deformation range of titanium alloy at room temperature is small, the amount of springback, gap sensitivity, in most cases need to be formed under thermal conditions. So to explore the hot forming state of titanium plate and forming the structure of the mold, whether it is economical, high-volume applications of titanium alloy material key. Our factory practice shows that within the proper temperature, time and pressure specifications, as long as the mold is reasonable, it is possible to obtain a stable quality part that basically no longer requires subsequent manual renovation. First, the formation of titanium parts A machine on a total of 21 kinds of titanium alloy parts, material grades TA2, TC1, material thickness of 0.5 to 1 mm. According to the shape of the parts, in accordance with the operation of the difficulty, the titanium plate parts of the forming scheme are shown in Table 1.
