【摘要】：高密齒散熱器型材由于其截面形狀復(fù)雜、舌比值(懸臂∶齒間距)大而使其擠壓模具設(shè)計難度大、試模成功率低。以某公司生產(chǎn)的高密齒散熱器鋁型材為例,采用數(shù)值模擬軟件Hyperxtrude對其擠壓成形過程進行分析研究。將原設(shè)計模具在仿真軟件上進行虛擬試模,找出可能存在的問題,再結(jié)合實際試模情況和模擬結(jié)果對模具結(jié)構(gòu)和參數(shù)進行多次優(yōu)化。主要通過改變導流板角度和工作帶尺寸,使得型材截面最大擠出速度與平均速度的比值趨近于1。結(jié)果表明:經(jīng)優(yōu)化后的模具消除了原來存在的問題,擠出了合格的高密齒型材。
[Abstract]:Because of its complicated section shape and large tongue ratio (cantilever: tooth spacing), the extrusion die design of high density radiator profile is difficult and the success rate of die test is low. Taking the aluminum profile of high density radiator produced by a company as an example, the extrusion forming process was analyzed and studied by numerical simulation software Hyperxtrude. The original design mould is simulated on the simulation software to find out the possible problems and then to optimize the mold structure and parameters several times by combining the actual mold test and simulation results. By changing the angle of the guide plate and the size of the working belt, the ratio of the maximum extrusion speed to the average velocity of the profile section approaches to 1. The results showed that the optimized die eliminated the original problems and extruded qualified high density profile.
