- 液壓自動彎管機(jī)設(shè)計(jì)隨著現(xiàn)代科技的高速發(fā)展，彎管技術(shù)已廣泛應(yīng)用于各個(gè)生產(chǎn)行業(yè)，特別是在鍋爐、壓力容器、石油石化工程等領(lǐng)域。本次課題研究的雙向彎管機(jī)是鍋爐行業(yè)廣泛使用的專業(yè)設(shè)備，屬于液壓彎管機(jī)，主要完成鍋爐部件所需蛇形管的彎制。
這次研究中主要設(shè)計(jì)出了雙向彎管機(jī)的模子提升裝置和液壓系統(tǒng)。模子提升裝置主要作用是使彎管模具提升或下降，因此，我們設(shè)計(jì)出其結(jié)構(gòu)主要由定位油缸、杠桿、和機(jī)架組成，由液壓泵提供動力，由杠桿傳遞，滿足使彎管模的提升。設(shè)計(jì)出了裝置的所有零件后，計(jì)算分析了主要零件的的受力、強(qiáng)度情況，并用Pro/E軟件進(jìn)行三維實(shí)體建模與裝配。
另外，我們設(shè)計(jì)了采用液壓為整個(gè)雙向彎管機(jī)提供動力，通過液壓泵輸出高壓油來滿足各個(gè)執(zhí)行元件的正常工作。主要設(shè)計(jì)出了液壓泵站、油箱和一些輔助元件。在管子的加工過程中，有加緊裝置、轉(zhuǎn)模裝置、提升裝置及模子橫移裝置都是采用液壓來提供動力的，因此液壓系統(tǒng)的設(shè)計(jì)尤其重要。

ABSTRACT
Along with the modern science and technology development, the elbow technology has widely applied in many realms of production, specially in the boiler, the pressure vessel as well as petroleum petrification project. Bidirectional pipe bending machine that we research is the specialized equipment used widespread in boiler profession, belongs to the hydraulic pressure pipe bending machine.It mainly curves the serpentuator pipes,which is a part of the boiler.
In this research we had mainly designed the mold lifting gear and the hydraulic system,which belong to the bidirectional pipe bending machine.The function of the mold lifting gear is that makes the elbow piece mold promotion or drop, therefore, we designed that was made by the locating cylinder, the release lever, and the base, provided the power by the hydraulic pump, transmited by the release lever, then makes the elbow piece mold promotion and drop. After designing all components of the installment, analyzing the stress, the intensity situation of the major parts, wo carried them on the three dimensional entity modelling and the assembly with the Pro/E software.
Moreover, we designs the hydraulic pressure provides the power for the bidirectional pipe bending machine, that can satisfy each functional element through the high-pressure oil outputed by hydraulic pump.We designe the station of hydraulic pressure pumping, the tank and some auxiliary parts. There are many installments provided power by hydraulic in the work of curving pipes, such as the step-up installment, the extension mold installment, the lifting gear ,
