    摘要:

    介紹了一種新型無(wú)模拉伸加工鈦管的成形方法及生產(chǎn)工藝。通過(guò)對(duì)鈦管無(wú)模拉伸變形機(jī)制的研究,分析了冷熱源運(yùn)動(dòng)速度、拉伸速度的變化規(guī)律,利用微積分原理和鈦管變形時(shí)的幾何規(guī)律,以及速度、位移、時(shí)間三者間的函數(shù)關(guān)系,建立了無(wú)模拉伸鈦管的數(shù)學(xué)模型,并在無(wú)模拉伸機(jī)上進(jìn)行了實(shí)驗(yàn)研究;實(shí)驗(yàn)證明,該模型結(jié)構(gòu)簡(jiǎn)單、精確可靠,具有實(shí)用價(jià)值。

    Abstract:

    A sort of new-style dieless drawing process titanium pipe shaped and the method of manufacture technology were introduced. The law of drawing speed was analyzed according to the deformation mechanism of titanium pipe dieless drawing. The mathematical model ofdieless drawing for titanium pipe has been set up, using calculus theory and titanium pipe geometry figure during dieless drawing and so on. It has been proved to true that the mathematical model is very simple, accurate, reliable, and practical through of experiment.
