The inside fashion of the sway oil pump stator is complex, its wall thickness is pockety and the metal flow law is difficult to master. at the present time, the investigation of warm extrusion forming technique for the nonuniform wall thickness forging has few to been done. the forming technique and die configuration which use for production have not achieve optimization
由於轉向油泵定子的內部形狀復雜，零件壁厚分佈不均，金屬流動規律難于掌握，目前人們對這種非均勻壁厚鍛件的溫擠壓成形工藝研究幾乎沒有，其成形工藝及生產用模具結構並未達到最優化。 -
According to the above theories, with using the software - deform - 3d, we have made the numerical analog simulation and analyse the warm extrusion forming technique process for sway oil pump stator, optimized the forming : technique and the die parameter for the pockety wall thickness forging this paper concretely analysis and research metal flow ' s characterize in different forming processes
本課題根據上述理論，利用有限元數值模擬模擬軟體deform - 3d ，對轉向油泵定子溫擠成形工藝過程進行模擬模擬分析，優化了油泵定子的成形工藝及模具參數。 -
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。 -
