摘 要: 鋁箔在清洗線出口卷取過程中常出現(xiàn)明顯的橫向起皺現(xiàn)象，嚴(yán)重時導(dǎo)致鋁箔橫向屈曲并產(chǎn)生廢料。為了掌握卷取過程鋁箔橫向起皺規(guī)律以及采用適當(dāng)方法來改善卷取過程屈曲問題，根據(jù)清洗線出口卷取設(shè)備實(shí)際情況，采用ABAQUS有限元軟件建立清洗線出口卷取過程動態(tài)仿真模型。針對當(dāng)前存在的橫向起皺和屈曲問題，利用該模型研究鋁卷凸度、鋁箔長寬比、鋁箔厚度、卷取張力、鋁箔屈服強(qiáng)度和鋁箔初始板形缺陷對鋁箔卷取過程橫向起皺和屈曲的影響，得出各因素對鋁箔橫向起皺和屈曲的影響規(guī)律，預(yù)測鋁箔發(fā)生屈曲的可能性。仿真得出的一系列結(jié)論為生產(chǎn)中卷取工藝的優(yōu)化提供理論依據(jù)，可以更有效地控制鋁箔橫向起皺和屈曲現(xiàn)象，減少廢料的產(chǎn)生。

Abstract:There are obvious transverse wrinkles in the aluminum foil coiling process at the exit of the cleaning line, which in serious cases causes transverse buckling flatness defect and a waste of aluminum foil. In order to grasp the wrinkling law of aluminum foil in the coiling process, and improve the aluminum foil flatness by taking appropriate measures, a dynamic simulation model was established based on the exit actual coiling equipment conditions of the cleaning line by the ABAQUS finite element software. Aiming at the current problems, the model was used to study the effects of aluminum coil crown, aluminum foil aspect ratio, aluminum foil thickness, coiling tension, aluminum foil yield strength and initial flatness defects on the aluminum foil transverse wrinkling and buckling in the coiling process. The influences of various factors on the transverse wrinkling and buckling of aluminum foil were obtained, and the prediction of the transverse buckling becomes possible. A series of conclusions obtained by the simulation provide a theoretical basis for the optimization of the coiling process in actual production, which can more effectively improve the aluminum foil flatness in the coiling process of the cleaning line and reduce the generation of waste.
