【摘要】：纖維纏繞的罐形容器由于具有優(yōu)良的性能,使其廣泛地應(yīng)用于化工、能源、冶金、航天等領(lǐng)域,在國民經(jīng)濟(jì)中發(fā)揮著重要作用。對于單一大批量罐形容器的生產(chǎn),結(jié)構(gòu)簡單、傳動可靠、維修方便、成本低的機械式纏繞機具有較大的優(yōu)勢。本文就是在現(xiàn)有的機械式纏繞機的基礎(chǔ)上,結(jié)合罐形容器的結(jié)構(gòu)特點,設(shè)計一臺適用于纏繞罐形容器的機械式纏繞機。 機械式纏繞機由小車、床頭箱、尾座等組成,主軸帶動芯模轉(zhuǎn)動,環(huán)鏈帶動小車運動,通過主軸與小車間的傳動比,完成罐形容器的纏繞。在纏繞過程中,為了保證纏繞線型的穩(wěn)定,導(dǎo)絲頭與芯模間的距離要保持不變。由于罐形容器筒身段是圓柱體,導(dǎo)絲頭在往復(fù)運動過程中,與芯模間的距離是恒定的。但罐形容器的封頭是橢球形的,為了保證導(dǎo)絲頭與芯模間距離的恒定,需要設(shè)計一伸臂機構(gòu),使其在纏繞封頭時推動導(dǎo)絲頭前進(jìn)后退,完成封頭的纏繞。本課題的關(guān)鍵就是設(shè)計出能完成封頭纏繞的伸臂機構(gòu)。 本文是在研究罐形容器的結(jié)構(gòu)特點及對現(xiàn)有纏繞機進(jìn)行研究的基礎(chǔ)上,最終以Pro/E為平臺,設(shè)計出了纏繞機的小車、床頭箱、尾座及伸臂機構(gòu),給出了纏繞機的各個零件的結(jié)構(gòu)圖,最終建立了纏繞機的三維模型。同時,為了對所設(shè)計的纏繞機有直觀的認(rèn)識,能比較真實地反映纏繞機的結(jié)構(gòu)特點及運動過程,檢驗各個機構(gòu)是否達(dá)到設(shè)計要求,以Pre/Mechanism為平臺完成纏繞機的機構(gòu)運動仿真。最后,為了保證纏繞機中零件結(jié)構(gòu)合理可靠,纏繞機能安全地工作,運用ANSYS軟件,對纏繞機中重要零件如槽輪,小車底板等進(jìn)行機構(gòu)分析,對出現(xiàn)的問題進(jìn)行修改。
[Abstract]:Because of its excellent performance, fiber winding can descriptor is widely used in chemical, energy, metallurgical, aerospace and other fields, and plays an important role in the national economy. The mechanical winding machine with reliable transmission, convenient maintenance and low cost has great advantages. This paper combines the structural characteristics of the can descriptor on the basis of the existing mechanical winding machine. A mechanical winding machine is designed for describing the winding tank. The mechanical winding machine consists of a small car, a headbox and a tail seat. The spindle drives the core mold to rotate, and the ring chain drives the car to move. Through the transmission ratio between the main shaft and the small workshop, the winding of the can descriptor is completed. In order to ensure the stability of the winding line, the distance between the guide wire head and the core die should be kept unchanged. Because the cylinder section of the can is a cylinder, the guide wire head is in the process of reciprocating. The distance from the core die is constant. However, the head of the can descriptor is ellipsoid. In order to ensure the constant distance between the guide wire head and the core die, an arm extension mechanism is designed to push the guide head forward and backward when winding the seal head. The key of this subject is to design the arm extension mechanism which can finish the winding of the head. Based on the study of the structure characteristics of the can descriptor and the research of the existing winding machine, the car, the headbox, the tail seat and the outstretched arm mechanism of the winding machine are designed on the platform of Pro/E. The structure diagram of each part of the winding machine is given, and finally the three-dimensional model of the winding machine is established. At the same time, in order to have an intuitive understanding of the designed winding machine, it can truly reflect the structure characteristics and motion process of the winding machine. In order to ensure that the structure of winding machine is reasonable and reliable, and the winding function works safely, the software ANSYS is used to verify whether each mechanism meets the design requirements and use Pre/Mechanism as the platform to complete the mechanism motion simulation of winding machine. The mechanism of the important parts of winding machine such as grooves and carts are analyzed and the problems are modified.
