軸向活塞泵是一種典型的同軸的泵，它的汽缸和傳動軸是平行的（如圖4—13），它的往復(fù)運動被一個平板形凸輪帶動，也叫擺動盤，傾斜盤，或旋轉(zhuǎn)斜盤。這個盤位于一個平面穿過主動軸和汽缸筒的同一軸線所以不能旋轉(zhuǎn)。在定量泵中，凸輪盤必須要嚴(yán)格的安裝在合適的位置上結(jié)果它與汽缸筒的中心線以垂線方向傾斜25度的角度交叉。..

注塑成型的智能模具設(shè)計工具-外文翻譯
-
本文描述的是一個CAD/CAE/CAM集成系統(tǒng)。在 CAD/CAE階段，注塑件的圖紙可與模具零件交互轉(zhuǎn)換，同時，根據(jù)用戶需求，可以進行機械檢驗、運行平衡分析、流動分析及冷卻模擬。在CAM階段，能夠生成線切割或銑床刀具路徑的數(shù)控磁帶。實踐表明：該系統(tǒng)是模具設(shè)計與制造的有用工具。注射成型是當(dāng)今工業(yè)最重要的聚合物加工方法之..
