| 目的 以喷油器体模锻成形为研究对象,对锻模结构与尺寸进行分析和优化设计。方法通过优化锻模设计(尤其是优化锁扣、终锻模膛、飞边槽、钳口、滚挤模膛等结构与尺寸设计以及根据滚挤模膛高度尺寸优选原材料下料规格),克服原锻模设计的缺点。结果 有效改善了喷油器体的模锻工艺性,减小了难变形区,减小了变形力,减少了原材料消耗0. 15 kg/ 件,提高了合格品率,提高了锻造效率(减少打击次数3 ~5 锤次/ 件),提高了锻模使用寿命至少1 倍,以及降低了锻模与锻件成本等。结论 最终获得的喷油器体锻模,结构高紧凑又强度足够,使用性能优越,可为类似锻模设计和实际生产提供了有力的参考依据。 |

| Objective This study used the fuel injector bodies die forging forming as the research object,analyzed and optimized the design of the forging die structure and size. Methods The original disadvantages of forging die design were avoided by optimal design of forging die (especially the design optimization of the structure and size of lock, finishing impression, flash cave, gate and edge rolling impression, and optimization of the raw materials blanking specification according to the height of the edge rolling impression). Results The fuel injector body die forging forming process was improved, the metal difficult deformation area and deformation force were reduced, the consumption was reduced by 0. 15 kg/ piece, the rate of qualified products and the forging efficiency (the hammer speed was reduced by 3 ~ 5 times/ piece) were increased, the service life of die forging was at least doubled and the cost was reduced. Conclusion The fuel injector bodies forging die finally obtained had compact structure, enough strength and superior performance, which provide powerful reference for the design and actual production of similar forging dies. |
