【摘要】：通过对汽车顶盖零件特点分析,介绍了顶盖的冲压工艺,设计了顶盖天窗侧整形模。根据生产需要,在第四工序的天窗翻边部位设计三组侧整形斜楔,侧整形凸模、凹模均要设在下模,模具可以成形出有天窗和无天窗的汽车顶盖这两种制件。重点介绍了顶盖天窗侧整形模中的两种双动斜楔结构的应用,在顶盖天窗左边位置采用两组对向的电车斜楔,布置在下模中部区域附近,由两个驱动块分开驱动,模具调整方便,结构稳定性好;在天窗前后侧位置采用复动斜楔,模具结构紧凑,节省了模具空间。通过本模具中对双动斜楔的灵活运用表明,模具结构稳定可靠,方便了制造与调试,节约了成本,保证了产品质量,提高了生产效率。
[Abstract]:Based on the analysis of the characteristics of automobile top cover parts, the stamping process of top cover is introduced, and the shaping die on the side of roof window is designed. According to the production needs, three groups of side shaping oblique wedges, side shaping punch and concave die should be set in the lower die in the flanging part of the skylight in the fourth working procedure. The die can form two kinds of parts: the roof cover with skylight and no skylight. This paper mainly introduces the application of two kinds of double action oblique wedges in the side shaping die of the top cover skylight. Two groups of opposite tram wedges are used in the left position of the top cover skylight, which are arranged near the middle area of the lower die and driven separately by two driving blocks. The die adjustment is convenient and the structure stability is good. In the front and back position of the skylight, the compound moving wedges are adopted, the die structure is compact, and the die space is saved. The flexible application of double moving wedges in this die shows that the die structure is stable and reliable, which is convenient for manufacture and debugging, saves cost, ensures product quality and improves production efficiency.
