研究了消除深孔薄壁挤压零件产生裂纹的措施 ,提出了用增大芯轴对孔的过盈量来提高金属塑性及内孔壁光洁度的方法 ,消除了裂纹的产生 ,制造出了使用性能较好的零件。
The measures to eliminate the cracks in the deep-hole thin-wall extrusion parts are studied. The method to increase the metal plasticity and the inner wall smoothness by increasing the interference of the mandrel to the hole is proposed, and the generation of cracks is eliminated. Better performance of the parts.
