液压自动弯管机设计随着现代科技的高速发展,弯管技术已广泛应用于各个生产行业,特别是在锅炉、压力容器、石油石化工程等领域。本次课题研究的双向弯管机是锅炉行业广泛使用的专业设备,属于液压弯管机,主要完成锅炉部件所需蛇形管的弯制。
这次研究中主要设计出了双向弯管机的模子提升装置和液压系统。模子提升装置主要作用是使弯管模具提升或下降,因此,我们设计出其结构主要由定位油缸、杠杆、和机架组成,由液压泵提供动力,由杠杆传递,满足使弯管模的提升。设计出了装置的所有零件后,计算分析了主要零件的的受力、强度情况,并用Pro/E软件进行三维实体建模与装配。
另外,我们设计了采用液压为整个双向弯管机提供动力,通过液压泵输出高压油来满足各个执行元件的正常工作。主要设计出了液压泵站、油箱和-些辅助元件。在管子的加工过程中,有加紧装置、转模装置、提升装置及模子横移装置都是采用液压来提供动力的,因此液压系统的设计尤其重要。

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 ,
