軸向擠壓
英文
axial compression-
In this paper the floral ontogeny and the ovary development of rivina humilis l. were observed. the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals. the abaxial one initiated first, then the adaxial one, finally the lateral two initiated nearly simultaneously. the third one initiated on the position near the first tepal, and there is a gap between itself and the second tepal. ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time. ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed, therefore an elliptic orifice was formed at the adaxial position of ovary, which was the remainder of the mouth of ovary before the ovary was fused completely. with the ovary maturing, the orifice was narrowed because of the ovary growth, at last fused completely. the gynoecium is composed of a single carpel. ( 4 ) in the series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed
對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: （ 1 ）數珠珊瑚花被呈2 / 5螺旋狀發生，遠軸側的1枚先發生，其次為近軸側的1枚發生，最後側方的2枚花被幾乎同時發生，第3枚花被在靠近第1枚的位置發生，第2枚和第3枚之間有1個空隙; （ 2 ） 4枚雄蕊是同時發生的; （ 3 ）心皮發生於分生組織的遠軸側，心皮原基形成后，向上向軸生長，在子房成熟前在近軸側非正中位形成1個孔，該孔為心皮最終愈合前的殘跡，到子房成熟時，因子房的生長孔被擠壓縮小，在進一步的生長過程中愈合.子房由1枚心皮構成; （ 4 ）從子房發育過程的切片看，該植物的胚珠是在子房發生后不久發生的，子房上的圓孔形成時，從近軸側的分生組織發生胚珠原基，由胚珠原基分化出珠被與珠心The globalization course was that the preformed texture recrystallized and became the granular equiaxed grain, when the temperature rose and the holding time prolonged, the granular grain melted at some area and at the liquid - solid interface the grain globalized at the role of the curvature overheated
過程機制為：擠壓形變組織在加熱過程中首先發生再結晶長大變為顆粒狀等軸晶；隨溫度升高和保溫時間延長，等軸晶發生局部熔化，液固界面的曲率過熱使晶粒外形向球狀轉變。In different in terne die travel, the metal flow characterize in warm extrusion forming processes and the affection for the flow of metal stage which made by the difference between the blank bottom altitude and the axial direction limiting size in warm extrusion forming technique have been analysed we have gotten the equivalent strain field and the velocity field and other field variable that the blank in different in terne die travel and the die travel - load curve. at the same time, we have analyzed the contributing factor for the oil pump stator forming process optimized and achieve thereasonable die parameter for the war m extrusion forming finally, the optimized technics parameters were used into pilot production, then the qualified oil pump stator forging were produced, the analog results were compared with those of pilot production
論文具體分析研究了不同成形工藝過程中金屬流動的特點，並對不同凸模行程下溫擠成形過程中的金屬流動特點、坯料連皮厚度（底部高度）與溫擠壓成形工藝中的軸向界限尺寸的差值對金屬變形階段的影響進行了分析，獲得了坯料在不同凸模行程下的等效應變場、速度場等場變量及凸模行程-載荷曲線，同時對油泵定子成形過程的影響因素等進行了分析，優化並獲得了合理的溫擠成形工藝及模具參數。最後，利用模擬優化獲得的各項工藝參數進行生產實驗，得到實際生產出的合格油泵定子件，並將模擬結果與生產實驗結果進行比較。Various successive partial plastic forming methods for processing groove, including thread rolling, cross rolling and skew rolling, splitting, rolling of spline shaft, split rolling, open - die extrusion of spline shaft / gear, extrusion of internal screwed tooth socket parts with large helical pitch, integral cold forging for slot commutator, extrusion - ploughing for outside fin tube, drawing of tube with spiral internal / external ribs etc. have been introduced briefly
摘要介紹了用於加工槽的各種連續局部塑性成形方法，包括螺紋軋制、橫軋與斜軋、分劈、花鍵軸滾軋、劈分軋制、花鍵軸齒輪開模擠壓、花鍵套擠壓、槽型換向器整體冷鍛、外翅片管擠壓一犁削、內外螺紋管拉拔等。In order to overcome the shortages resulted from hypothesis of small deformation in radial symmetry based on thick - wall cylinder, plane stress and uniform pressure about residual stress around cold - expanded hole, a new model was proposed which takes into consideration the effect of split - sleeve, the different states along thick direction of specimen
摘要針對目前在研究冷擠壓孔邊殘餘應力時，大都採用基於厚壁圓筒的軸對稱小變形、平面應力狀態、孔邊受力為均布載荷等假設所帶來的不足，提出了在三維真實模型狀態下，考慮襯套對孔邊受力的影響、試件在厚度方向上的應力差異等因素。26 mm co - rotating segmented screws where each segment can be placed anywhere on the hexagonal screw core shaft for optimum flexibility of screw configurations. the kneading elements are supplied as single sectors that can be placed against each other in various angles enabling numerous kneading and shearing functions
