模具是汽車工業(yè)的基礎(chǔ)工藝裝備，在汽車生產(chǎn)中90%以上的零部件都需要依靠模具成形。制造一輛普通轎車需1500套模具，其中沖壓模具占1000余套。在新車型的開發(fā)中，90%的工作量都是圍繞車身型面的改變而進(jìn)行的。在新車型的開發(fā)費(fèi)用中，約有60%用于車身和沖壓工藝及裝備的開發(fā)。在整車制造成本中約40%為車身沖壓件及其裝配的費(fèi)用。未來模具服務(wù)于汽車制造業(yè)的比重將不斷上升。按汽車模具占模具行業(yè)約1/3的市場份額測算，2014年汽車模具市場規(guī)模達(dá)到6000億元。我國重點(diǎn)骨干模具企業(yè)達(dá)到近110家，其中，沖壓模具約占37%，這些數(shù)據(jù)有力地證明了我國已經(jīng)成為汽車模具制造大國的事實(shí)。 </p><p style="text-indent:25px">模具損耗原因 1）模具主要工作零件的材料的問題，選材不當(dāng)。材料性能不良，不耐磨；模具鋼未經(jīng)精煉，具有大量的冶煉缺陷；凸凹模，鍛坯改鍛工藝不完善，遺存有熱處理隱患。 2）模具結(jié)構(gòu)設(shè)計(jì)問題，沖模結(jié)構(gòu)不合理。細(xì)長凸模沒有設(shè)計(jì)加固裝置，出料口不暢出現(xiàn)堆集，卸料力過大使凸模承受交變載荷加劇等。 3)制模工藝不完善，主要表現(xiàn)在凸、凹模鍛坯內(nèi)在質(zhì)量差，熱處理技術(shù)及工藝有問題，造成凸、凹模淬不透，有軟點(diǎn)及硬度不均。有時(shí)產(chǎn)生微裂紋、甚至開裂，研磨拋光不到位，表面粗糙度值過大。 4)無潤滑或有潤滑但效果不佳、模具使用企業(yè)要做詳細(xì)記載、統(tǒng)計(jì)其使用、護(hù)理(潤滑、清洗、防銹)及損壞情況。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="濰坊模具供應(yīng)商,模具"
