【摘要】：隨著工業(yè)與科技的快速發(fā)展,行業(yè)中冷軋鈦管的需求量越來越大,質(zhì)量要求也越來越高。本文以張家港某金屬制品廠LG30冷軋管機(jī)為研究對(duì)象,在該廠現(xiàn)有軋具孔型設(shè)計(jì)理論的基礎(chǔ)上,對(duì)軋具孔型曲線進(jìn)行了優(yōu)化研究:首先,借助Pro/E5.0軟件和DEFORM-3D有限元軟件進(jìn)行了LG30冷軋管機(jī)的鈦管冷軋成形過程的模擬仿真,對(duì)軋制力的變化規(guī)律及軋成管的尺寸精度進(jìn)行了分析。其次,以軋制力的變化規(guī)律和軋成管的尺寸精度為研究目標(biāo),結(jié)合有限元分析法,從開口形狀和開口尺寸兩個(gè)方面采用了三種方法對(duì)軋具的孔型曲線進(jìn)行了優(yōu)化研究:第一、通過分析孔型開口曲線的五組開口角來研究了開口形狀。根據(jù)4副軋具的有限元分析和實(shí)際軋制的結(jié)果,得出了開口角為25o時(shí),減壁量小于4mm的軋成管有較好的尺寸精度。第二、采用調(diào)整7個(gè)孔型設(shè)計(jì)參數(shù)來研究開口尺寸,以軋制力仿真值得變化規(guī)律作為參考依據(jù),調(diào)整相關(guān)參數(shù)得到軋制力計(jì)算值的變化規(guī)律比較接近仿真值變化規(guī)律時(shí)的一組參數(shù)組合,有限元分析及實(shí)際軋制結(jié)果證明了該組參數(shù)下的軋成管尺寸精度有所改善。第三、采用正交試驗(yàn)法來研究開口尺寸,對(duì)7個(gè)孔型設(shè)計(jì)參數(shù)分別設(shè)置4個(gè)水平值,設(shè)計(jì)正交表L32(49)并進(jìn)行了模擬試驗(yàn),利用極差分析法分析得到各參數(shù)對(duì)目標(biāo)函數(shù)的影響規(guī)律及影響程度,得出了各參數(shù)影響程度的主次順序,根據(jù)極差值和參數(shù)影響的主次順序,綜合分析得到了軋具孔型優(yōu)化的最佳參數(shù)組合,在此基礎(chǔ)上進(jìn)行了冷軋鈦管過程的有限元分析及實(shí)軋檢驗(yàn),結(jié)果顯示優(yōu)化后軋制力曲線的變化規(guī)律更理想,且軋成管的尺寸精度更高。最后,分析了以上三種研究方法所得結(jié)論的優(yōu)缺點(diǎn),并對(duì)正交試驗(yàn)法所得結(jié)論的普遍適用性進(jìn)行了20組不同軋制規(guī)格的實(shí)軋檢驗(yàn),結(jié)果顯示,90%的軋具軋制效果比較理想。
[Abstract]:With the rapid development of industry and science and technology, the demand for cold-rolled titanium tubes in the industry is becoming more and more large, and the quality requirements are becoming higher and higher. In this paper, a Zhangjiagang metal products factory LG30 cold rolling mill as the research object, based on the existing factory with rolling pass design on the theory of rolling out pass curves were studied: firstly, the simulation of cold roll forming process of LG30 cold rolling mill of the titanium tube with the help of Pro/E5.0 software and DEFORM-3D finite element software. Variation of rolling force and rolling into the size precision tube were analyzed. Second, changes to the rolling force and rolling into the size precision tube as the research object, combined with finite element analysis method, from the opening shape and size of the openings in two aspects, three methods are adopted to study the optimization of the rolling pass out curve: first, through the analysis of pass opening curve five group opening angle study on the shape of the opening. According to the finite element analysis and the actual rolling results of the 4 pair rolling gear, it is found that when the opening angle is 25o, the rolled tube with reduced wall less than 4mm has better dimensional precision. Second, by adjusting the 7 pass design parameters to study the opening size, the rolling force variation is simulation as a reference, changes and adjust relevant parameters calculated value of rolling force is close to the simulation of a group of parameters variation of the finite element analysis and the actual rolling results show that the parameters of the group rolled tube size accuracy has improved. Third, to study the size of the opening by the orthogonal test, the 7 pass design parameters were set up 4 level orthogonal table L32 (49) and conducted simulation experiments and analysis have influence and impact of various parameters on the objective function by using range, the parameters influencing order degree according to the order, range and influence of parameters, are analyzed and the optimum parameters of rolling out pass optimization, on the basis of the finite element analysis of the process of cold rolling of titanium tube and rolling test, the results show that the optimal variation of rolling force curve is more ideal, and rolled into more precision tube high. Finally, the advantages and disadvantages of the above three research methods are analyzed, and the general applicability of the conclusions obtained by the orthogonal test method is tested on 20 different rolling specifications. The results show that the rolling effect of 90% kinds of rolling tools is ideal.
