【摘要】：珍珠巖吸音板作為一種新型建材,具有吸聲、防火、保溫等多種功能,具有日益廣闊的市場空間。但目前吸音板的生產(chǎn)方式多為半自動(dòng)化生產(chǎn),生產(chǎn)效率低下、成本高、產(chǎn)品質(zhì)量難以保證,為了滿足日益增長的珍珠巖吸音板市場需求,在國內(nèi)現(xiàn)有珍珠巖吸音板加工設(shè)備的基礎(chǔ)上進(jìn)行自動(dòng)化生產(chǎn)線的設(shè)計(jì)與改進(jìn),提供一條能夠穩(wěn)定運(yùn)行、生產(chǎn)效率較高的珍珠巖吸音板自動(dòng)化生產(chǎn)線具有重大的意義。為此,本論文設(shè)計(jì)研究了一種吸音板帶式自動(dòng)化生產(chǎn)線,其具有生產(chǎn)效率高、設(shè)備穩(wěn)定性強(qiáng)、成品質(zhì)量高的特點(diǎn)。本論文首先依據(jù)企業(yè)對(duì)珍珠巖吸音板生產(chǎn)線的生產(chǎn)要求,分析了現(xiàn)有的平推上下循環(huán)式吸音板生產(chǎn)線、圓盤回轉(zhuǎn)式吸音板生產(chǎn)線以及無模具生產(chǎn)線的工作方式,著重針對(duì)無模具生產(chǎn)線方案的優(yōu)勢(shì)與不足,結(jié)合對(duì)珍珠巖物料沖壓理論分析,擬定了吸音板帶式生產(chǎn)線的總體設(shè)計(jì)方案,確定了主線的基本結(jié)構(gòu)形式。其次,論文分別針對(duì)帶式生產(chǎn)線主線中的上層輸送鏈、下層輸送帶、液壓沖壓機(jī)等主體結(jié)構(gòu)及其配套裝置進(jìn)行了理論分析與結(jié)構(gòu)設(shè)計(jì),完成了相關(guān)參數(shù)的計(jì)算,并借助SolidWorks三維設(shè)計(jì)軟件完成了主線各零部件的三維建模以及主線整機(jī)的三維裝配,驗(yàn)證結(jié)構(gòu)設(shè)計(jì)和各部分之間的配合關(guān)系是否合理,也為后面的仿真分析提供了模型支持。最后,結(jié)合前面所建立的主線機(jī)構(gòu)的三維模型,運(yùn)用ANSYS Workbench軟件對(duì)吸音板帶式生產(chǎn)線主線的下層輸送帶驅(qū)動(dòng)滾筒進(jìn)行動(dòng)力學(xué)仿真,對(duì)上層輸送鏈做了接觸分析。通過對(duì)驅(qū)動(dòng)滾筒的模態(tài)分析得出了其前6階固有頻率和相應(yīng)的振型等,并以驅(qū)動(dòng)滾筒兩個(gè)參數(shù)為變量對(duì)其進(jìn)行了動(dòng)力學(xué)優(yōu)化設(shè)計(jì),有效改進(jìn)了驅(qū)動(dòng)滾筒的動(dòng)力學(xué)特性,使其在工況下的抗振性顯著增強(qiáng);對(duì)上層輸送鏈的接觸分析也驗(yàn)證了上層輸送鏈設(shè)計(jì)的可靠性,為吸音板生產(chǎn)線的設(shè)計(jì)和方案的實(shí)際應(yīng)用提供了有力的理論依據(jù)。
[Abstract]:As a new type of building materials, perlite sound-absorbing board has many functions, such as sound absorption, fire prevention, heat preservation and so on.However, at present, most of the production methods of sound-absorbing boards are semi-automatic. The production efficiency is low, the cost is high, and the quality of the products is difficult to guarantee. In order to meet the increasing market demand of perlite sound-absorbing boards,It is of great significance to design and improve the automatic production line on the basis of the existing perlite sound-absorbing plate processing equipment in China, and to provide an automatic production line of perlite sound-absorbing plate with stable operation and high production efficiency.Therefore, this paper designs and researches a kind of automatic production line of sound-absorbing plate and belt, which has the characteristics of high production efficiency, strong stability of equipment and high quality of finished product.Firstly, according to the production requirements of perlite sound-absorbing plate production line, this paper analyzes the working methods of the existing horizontal push up-and-down circulatory sound-absorbing plate production line, the disc rotary sound-absorbing plate production line and the no-mould production line.In view of the advantages and disadvantages of the production line without mould, combined with the theoretical analysis of perlite material stamping, the overall design scheme of the sound-absorbing plate and belt production line is drawn up, and the basic structural form of the main line is determined.Secondly, the paper carries on the theoretical analysis and structural design for the main structure of the upper conveying chain, the lower conveyor belt, the hydraulic punching machine and its supporting devices in the main line of the belt production line, and completes the calculation of the related parameters.With the help of SolidWorks 3D design software, the 3D modeling of each part of the main line and the 3D assembly of the mainline machine are completed, which verifies whether the structural design and the coordination relationship between the parts are reasonable or not, and also provides the model support for the simulation analysis in the future.Finally, combined with the 3D model of the main line mechanism, the dynamic simulation of the lower conveyor belt driving drum in the main line of the sound-absorbing plate and belt production line is carried out by using ANSYS Workbench software, and the contact analysis of the upper conveying chain is made.Based on the modal analysis of the driving drum, the first 6 natural frequencies and the corresponding vibration modes are obtained, and the dynamic optimization design of the driving drum is carried out with two parameters as variables, which effectively improves the dynamic characteristics of the driving drum.The contact analysis of the upper transport chain also verifies the reliability of the design of the upper transport chain, which provides a powerful theoretical basis for the design and practical application of the sound-absorbing plate production line.
