在省油器表面形成許多凹凸面：使表面受熱面積加大，促進(jìn)吸收光能及熱能，增加紅外線放射能量。 - As a new type gear transmission , double circular arc profile bevel gearing carries out its transmission by means of meshing between convex - concave tooth profile in both of the direction of tooth trace and the direction of tooth depth , so it has advantage of high load capacity , long service life , easy forming hydrodynamic oil film between teeth as well as high quality of running - in etc . therefore , more attention has been paid to its application and research in recent years
作為一種新型齒輪傳動(dòng)方式，雙圓弧弧齒錐齒輪傳動(dòng)不論在齒線方向、還是在齒高方向，均為凸、凹齒廓相嚙合，因而它比一般的弧齒錐齒輪傳動(dòng)的承載能力高，使用壽命長(zhǎng)；并且在嚙合過(guò)程中兩齒面間容易形成潤(rùn)滑油膜，具有良好的跑合性能，所以對(duì)它的應(yīng)用和研究日益受到人們的重視。 - This paper referred to the massive domestic and foreign technical material , elaborated in the sheet forming value simulation theory essential technology in detail , points out when analysis sheet forming question should use the big distortion ball plasticity fem and introduce the application characteristic and the function summarizes of the sheet forming simulation software dynaform . secondly , analyzed the cover forming characteristic , simultaneously introduced the influence cover forming factor in detail : such as ramming direction , the craft addendum surface and the material pressing surface , the radius of convex - concave mold , draw bead , pressure strength , blank size and craft margin and so on . and simulates many typical automobiles cover panel with software : such lateral board , back taillight pedestal and storage cover
其次,分析了覆蓋件成形的特點(diǎn)和要求,同時(shí)詳細(xì)介紹了影響覆蓋件成形的因素如沖壓方向、工藝補(bǔ)充面和壓料面、凸凹模圓角、拉延筋、壓邊力、坯料尺寸和工藝切口等,并用數(shù)值模擬軟件對(duì)多個(gè)典型的汽車覆蓋件汽車后側(cè)圍板、后燈座以及轎車后備箱蓋的沖壓成形情況進(jìn)行模擬,用模擬結(jié)果優(yōu)化拉延工藝方案,比較了內(nèi)覆蓋件和外覆蓋件在成形特點(diǎn)和要求的一些異同點(diǎn),以及常見(jiàn)的起皺、拉裂和回彈、成形不足等缺陷的產(chǎn)生機(jī)理和相應(yīng)對(duì)策,重點(diǎn)介紹工藝補(bǔ)充面和壓料面的設(shè)計(jì)及優(yōu)化方法,因?yàn)槔邮菦_壓工藝的關(guān)鍵工序,而工藝補(bǔ)充面和壓料面的設(shè)計(jì)是拉延工序的關(guān)鍵,對(duì)消除缺陷至關(guān)重要。
