通过对某复杂承力构件等温挤压成形结果的分析,发现在常规等温挤压方法下锻件的部分区域有充不满现象。对此,经过对成形工艺和模具设计的改进,大大改善了成形效果。试验结果表明:通过增加预制坯工序,可以有效地优化锻件口部的成形效果;适度增加锻件底部厚度和改进垫板,可以有效改善底部的筋部充不满现状。 Through the analysis of the result of isothermal extrusion forming of a complex bearing member, it is found that some areas of the forging are unsatisfactory under the conventional isothermal extrusion method. In this regard, after the forming process and mold design improvements, greatly improving the forming effect. The test results show that the forming effect of the forging mouth can be effectively optimized by increasing the preform process. Moderately increasing the thickness of the bottom of the forging and improving the backing plate can effectively improve the unsatisfactory status of the bottom reinforcement.
