摘要
为更好地进行冷滚打工艺参数选择,减少成形件缺陷提高制件成形质量,针对高速冷滚打成形过程缺陷中比较常见的鳞纹缺陷进行研究。阐述了板料冷滚打成形的原理;分析了影响板料冷滚打成形以及板料冷滚打成形鳞纹缺陷产生的各种因素;对板料冷滚打鳞纹缺陷进行了理论解析,获得了鳞纹纵向波纹不平度与相关工艺参数之间的关系表达式;对工艺参数如进给量、滚打轮转速等对鳞纹纵向波纹不平度的影响进行了分析。在自行开发的冷滚打成形设备上进行了板料冷滚打成形试验,并对鳞纹高度进行了测量,验证了理论解析的正确性。
To select optimally the technology parameters of cold roll-beating to decrease flaws and improve the qual- ity of the finished parts, the common flaws of strip in cold roll-beating are studied in this paper. The principle of slab cold roll-beating forming is discussed and the factors affecting slab cold roll-beating and strip occurring are ana- lyzed. Theoretical analysis of stripe flaw is carried out and expression of relation between the characterization pa- rameters （ vertical corrugated roughness and stripe interval） of stripe and related technology parameters is obtained. Effects of technology parameters such as feed and rotating speed of the roller on vertical corrugated roughness of the stripe is analyzed. Forming experiments are carried out with self-developed cold roll-beating experimental equip- ment and the height of stripe is measured to verify the correctness of theoretical analysis above.
