摘要
针对采油过程中抽油杆易出现偏磨、断脱等不良现象,对抽油杆结构进行优化设计,提出两种抽油杆平锻工艺方案,并利用有限元方法对两种平锻工艺方案进行模拟。仿真结果表明:通过设计模具,将抽油杆斜槽直接锻造的方案2获得的抽油杆锻件出现充不满、损伤的现象,且不满足净尽成形的特点;在锻造过程中不锻造出斜槽而在后续机械加工中制造的方案1尽管增加一道机加工工序,但是锻件质量良好,最后通过抽油杆的实际生产验证了工艺方案模拟结果的合理性。
Aiming at the undesirable phenomena such as eccentric wear and broken-off of sucker rod during the oil extraction process, the structure of sucker rod was optimized. Two process schemes of sucker rod horizontal forging were proposed, and the FEM simulation was applied to compare and analyze the forming results. It is found that the phenomena of unfilling and damage of sucker rod forgings appear in Scheme 2 that the chute of sucker rod is forged by the forging mold redesigned, and this process scheme do not meet the characteristics of net shape forging. The machining process is added in Scheme 1 that the chute of sucker rod is manufactured by subsequence machi- ning, but the forming quality using Scheme 1 is better. The rationality of process schemes and simulation results were verified by the actu- al production of sucker rod finally.
