【摘要】：單點(diǎn)增量成形過(guò)程中的變形能對(duì)加工成本控制及工具頭與材料之間的熱效應(yīng)和摩擦效應(yīng)有直接影響。以典型圓錐形制件為研究對(duì)象,采用BBD實(shí)驗(yàn)方法,設(shè)計(jì)四因素三水平實(shí)驗(yàn)方案,利用響應(yīng)面法研究工具頭直徑d、層間距Z、板厚t和成形角α對(duì)變形能的影響,并得到變形能的多元二次預(yù)測(cè)模型,最后以變形能最小為目標(biāo)對(duì)該模型進(jìn)行優(yōu)化。實(shí)驗(yàn)結(jié)果表明:板厚對(duì)變形能的線性影響最顯著,隨著板厚的增大變形能增大,工具頭直徑越大所需變形能越大,成形角增大時(shí)所需的變形能增大;變形能最小的工藝參數(shù)組合是工具頭直徑4.0mm、層間距0.95mm、板厚0.57mm、成形角45°。
[Abstract]:The deformation energy in the process of single point incremental forming has a direct effect on the control of machining cost and the thermal and friction effects between the tool head and the material. Taking typical conical parts as the research object, a four-factor three-level experimental scheme was designed by using BBD method. The effects of tool head diameter d, layer spacing Z, plate thickness t and forming angle 偽 on deformation energy were studied by response surface method. The multivariate quadratic prediction model of deformation energy is obtained, and the model is optimized with the objective of minimum deformation energy. The experimental results show that the linear effect of plate thickness on deformation energy is the most significant. With the increase of plate thickness, the larger the diameter of the tool is, the greater the deformation energy is, and the more the deformation energy is when the forming angle increases. The process parameters of minimum deformation energy are: tool head diameter 4.0mm, layer spacing 0.95mm, plate thickness 0.57mm, forming angle 45 擄.
