1、單向壓制單向壓制工作原理：陰模型腔和下模沖的位置固定不動，徐州金屬粉末冶金，上模沖在壓機凸輪帶動下，向下進入陰模型腔，并對陰模型腔的粉末加壓，徐州金屬粉末冶金，使粉末壓制成具有一定密度和強度的坯件。 </p> <p> 單向壓制的一個循環(huán)有以下步驟：A粉末充填：粉末通過手工或者動送粉器的送粉，利用粉末重力充填在陰模型腔中。B單向壓制：粉末填充完畢后，陰模型腔與下模沖位置固定不變，上模沖在壓機凸輪帶動下，向下進入陰模型腔，使粉末壓制成成具有一定密度和強度的坯件。C保壓：為了使壓力得到有效傳遞，使坯件密度分布均勻，上模沖應在180度的成型壓制位置下保持不動一段時間，使坯件中空氣有足夠時間逸出，徐州金屬粉末冶金。D脫模：保壓結束后，上模沖由壓機凸輪復位帶動向上脫離陰模型腔，下模沖則由壓機的下氣缸的作用力作用下把坯件頂出陰模型腔。E復位：上模沖退到高點，送粉器把壓制的坯件推出，同時下模沖退回固定位置，同時粉末在重力作用下充填在陰模型腔中。

粉末冶金是制取金屬粉末或用金屬粉末(或金屬粉末與非金屬粉末的混合物)作為原料，經過成形和燒結，制取金屬材料、復合材料以及各種類型制品的工業(yè)技術。粉末冶金技術已被廣泛應用于交通、機械、電子、航空航天、兵器、生物、新能源、信息和核工業(yè)等領域，成為新材料科學中相當有發(fā)展活力的分支之一。粉末冶金技術具備明顯節(jié)能、省材、性能優(yōu)異、產品精度高且穩(wěn)定性好等一系列優(yōu)點，非常適合于大批量生產。另外，部分用傳統(tǒng)鑄造方法和機械加工方法無法制備的材料和復雜零件也可用粉末冶金技術制造，因而備受工業(yè)界的重視。

近年來，一系列粉末冶金新的成形技術層出不窮，并呈現(xiàn)出加速發(fā)展態(tài)勢,金屬注射成形、溫壓成形、流動溫壓成形、噴射成形、高速壓制成形等新技術不斷涌現(xiàn),使得粉末高致密化成形技術得到了很大的發(fā)展。 </p> <p> 包括電工材料和磁性材料。電工材料中，用作電能頭材料的有金、銀、鉑等貴金屬的粉末冶金材料和以銀、銅為基體添加鎢、鎳、鐵、碳化鎢、石墨等制成的粉末冶金加工材料;用作電極的有鎢銅、鎢鎳銅等粉末冶金材料;用作電刷的有金屬-石墨粉末冶金材料;用作電熱合金和熱電偶的有鉬、鉭、鎢等粉末冶金材料。磁性材料分為軟磁材料和硬磁材料。軟磁材料有磁性粉末、磁粉芯、軟磁鐵氧體、矩磁鐵氧體、壓磁鐵氧體、微波鐵氧體、正鐵氧體和粉末硅鋼等;硬磁材料有硬磁鐵氧體、稀土鈷硬磁、磁記錄材料、微粉硬磁、磁性塑料等。用于制造各種轉換、傳遞、儲存能量和信息的磁性器件。
