【摘要】：隨著經(jīng)濟(jì)的高速發(fā)展，鋼卷的需求量逐日遞增。在鋼卷生產(chǎn)到完成的過程中，鋼卷的立式和臥式狀態(tài)需要重復(fù)不斷的進(jìn)行轉(zhuǎn)換，鋼卷生產(chǎn)到完成的過程中，鋼卷的立式和臥式狀態(tài)需要重復(fù)不斷的進(jìn)行轉(zhuǎn)換，目前市場上的鋼卷翻轉(zhuǎn)機(jī)雖然可以安全完成鋼卷的翻轉(zhuǎn)，但是效率低，成本高，并不是中小企業(yè)的最佳選擇。為了提高鋼鐵企業(yè)的生產(chǎn)效率，完成鋼卷的翻轉(zhuǎn)和運(yùn)輸成為了一個(gè)棘手問題。本課題研究的鋼卷空中翻轉(zhuǎn)夾鉗，可以在空中完成鋼卷的翻轉(zhuǎn)，并由起吊裝置直接調(diào)運(yùn)到運(yùn)輸設(shè)備中，大大提高了生產(chǎn)效率，節(jié)省了大量的資源。 鋼卷空中翻轉(zhuǎn)夾鉗結(jié)構(gòu)復(fù)雜，且鋼卷的重量高達(dá)到幾十噸，在翻轉(zhuǎn)過程中易發(fā)生鋼卷脫落等事故，若發(fā)生事故，輕則損壞設(shè)備，重則造成人員傷亡。因此應(yīng)用虛擬技術(shù)對夾鉗的強(qiáng)度進(jìn)行驗(yàn)算，對其安全性尤為重要。本文所設(shè)計(jì)的翻轉(zhuǎn)夾鉗最大可承受的鋼卷重量為30噸，翻轉(zhuǎn)轉(zhuǎn)速為3r/min，在翻轉(zhuǎn)過程要求平緩，無明顯的沖撞。 本文主要從以下三個(gè)方面對鋼卷空中翻轉(zhuǎn)夾鉗進(jìn)行了研究和分析：首先，應(yīng)用SolidWorks軟件提供的建模功能完成鋼卷空中翻轉(zhuǎn)夾鉗的虛擬樣機(jī)建模操作，同時(shí)對模型進(jìn)行全局干涉分析，以檢驗(yàn)設(shè)計(jì)的合理性、可制造性和可裝配性；其次，利用ADAMS分析軟件對鋼卷空中翻轉(zhuǎn)夾鉗進(jìn)行了運(yùn)動(dòng)仿真模擬分析。模擬三個(gè)過程，夾鉗加緊、上升、翻轉(zhuǎn)。通過對各個(gè)過程的分析得到了相關(guān)的運(yùn)動(dòng)曲線圖,包括速度、位移等曲線，確定了鋼卷在上升過程中的受力情況；最后，利用ANSYS對夾鉗的主要零部件進(jìn)行靜態(tài)強(qiáng)度分析，，驗(yàn)證設(shè)計(jì)的合理性。
[Abstract]:With the rapid development of economy, the demand for steel coils is increasing day by day. In the process of coil production and completion, the vertical and horizontal states of steel coils need to be changed repeatedly and continuously. The vertical and horizontal status of the steel coil needs to be repeatedly and continuously converted. Although the steel coil flipping machine in the market can safely complete the roll reversal, it is low efficiency and high cost. It is not the best choice for small and medium-sized enterprises. In order to improve the production efficiency of iron and steel enterprises, it has become a thorny problem to complete the rolling and transporting of steel coils. And the lifting device is directly transferred to the transportation equipment, which greatly improves the production efficiency and saves a lot of resources. The structure of roll clamp in the air is complex, and the weight of steel coil is up to several tens of tons. During the turning process, accidents such as coil shedding will occur easily. If an accident occurs, the equipment will be damaged lightly. Therefore, using virtual technology to check the strength of the clamp is particularly important for its safety. The maximum weight of the roll clamp designed in this paper is 30 tons. The rotation speed is 3 r / min, which is smooth and has no obvious impact. In this paper, the following three aspects are studied and analyzed: firstly, the virtual prototype modeling operation of the roll flip clamp is accomplished by using the modeling function provided by SolidWorks software. At the same time, the global interference analysis of the model is carried out to verify the rationality, manufacturability and assemblability of the design. Secondly, the motion simulation analysis of the roll flip clamp is carried out by using ADAMS software. Through the analysis of each process to obtain the relevant motion curve, including velocity, displacement and other curves, determine the steel coil in the rising process of the force; finally, The static strength of the main parts of the clamp is analyzed by ANSYS, and the rationality of the design is verified.
