雙向壓制雙向壓制一般分為陰模浮動(dòng)式壓制和陰模拉下式壓制。粉末治金陰模浮動(dòng)式壓制陰模浮動(dòng)式壓制工作原理：陰模由彈簧支承，處于浮動(dòng)狀態(tài)，下模沖固定不動(dòng)，上模沖在凸輪帶動(dòng)下向下進(jìn)入陰模型腔，對(duì)粉末施加向下壓力。開始加壓時(shí)，由于粉末與陰模型腔壁間摩擦力小于彈簧支承力，只有上模沖向下移動(dòng)，隨著壓力增大，粉末對(duì)陰模型腔壁間的摩擦力大干彈簧支承力時(shí)，陰模型腔與上模沖一起向下運(yùn)動(dòng)，與下模沖間產(chǎn)生相對(duì)移動(dòng)，從而達(dá)到雙向壓制的效果。陰模浮動(dòng)式壓制的一個(gè)循環(huán)有以下步驟。A裝料：手工或者由自動(dòng)送粉器把粉末均勻裝入陰模型腔。B上沖下壓：粉末填充完畢后，陰模彈簧支撐，下模沖位置固定不變，粉末冶金制造廠，上模沖在壓機(jī)凸輪帶動(dòng)下，粉末冶金制造廠，向下進(jìn)入陰模型腔，對(duì)陰模型腔中的粉末施加向下壓力。C陰模浮動(dòng)：隨著上模沖施加的壓力不斷增大，粉末對(duì)陰模型腔壁間的摩擦力也不斷增大，當(dāng)此摩擦力大干陰模型腔的彈簧支撐力時(shí)，粉末冶金制造廠，陰模型腔與上模沖一起向下運(yùn)動(dòng)，直到坯件成型。

雖然粉末冶金齒輪在整個(gè)粉末冶金零件中難以單獨(dú)統(tǒng)計(jì)，但無論是按重量還是按零件數(shù)量，粉末冶金齒輪在汽車、摩托車中所占的比例都遠(yuǎn)遠(yuǎn)大于其他領(lǐng)域中的粉末冶金零件。因此，從汽車、摩托車在整個(gè)粉末冶金零件中所占比例的上升可以看出，粉末冶金齒輪在整個(gè)粉末冶金零件中處于飛速發(fā)展的地位。2016-2021年中國(guó)粉末冶金齒輪行業(yè)市場(chǎng)供需前景預(yù)測(cè)深度研究報(bào)告表明，齒輪看起來并不起眼，但它卻是工業(yè)設(shè)備重要的組成部分。 </p> <p> 我國(guó)齒輪行業(yè)基本由三部分組成，即工業(yè)齒輪、車輛齒輪和齒輪裝備。其中，車輛齒輪的市場(chǎng)份額達(dá)到60%；工業(yè)齒輪由工業(yè)通用、**、特種齒輪構(gòu)成，其市場(chǎng)份額分別為18%、12%、8%;齒輪裝備占市場(chǎng)份額的2%。 </p><div style="width:100%;text-align:

國(guó)內(nèi)的企業(yè)大部分處于根據(jù)別人的設(shè)計(jì)圖來進(jìn)行加工的水平，一般情況下**承擔(dān)工藝的研發(fā)，這其實(shí)不能算是真正的產(chǎn)品研發(fā)。由于起步較晚國(guó)內(nèi)企業(yè)的技術(shù)創(chuàng)新能力比較差，**在消化吸收以及模仿創(chuàng)新上下功夫，而完全的原始創(chuàng)新力度還不夠，另外在產(chǎn)品研發(fā)過程中的管理水平還有待提高。盡管我國(guó)的汽車粉末冶金行業(yè)建立了有效的質(zhì)量管理體系，企業(yè)生產(chǎn)的產(chǎn)品得到廣大用戶的一致認(rèn)可，但是在過程控制方面以及產(chǎn)品質(zhì)量水平仍然不能與發(fā)達(dá)國(guó)家相提并論。
