摘要：

油箱端盖被用来封闭汽车油箱筒体端部，使其内外介质隔离。针对铝合金油箱端盖成形过程中存在口部负角顺畅收缩的难点，根据油箱端盖的成形特点，提出采用特殊斜楔机构来实现侧向周圈的一次成形；通过增加吸料筋规划端盖口部材料收口时的流向，在实现零件刚性提高的同时，保证其与筒体配合部分形状轮廓的清晰度，以满足焊接需求。实践证明：通过以上工艺改善和收口模具结构设计，不仅提高了端盖产品的尺寸精度及外观质量，同时也减少了装配难度，提高了生产效率。

The end cap of fuel tank is used to close the end of automobile fuel tank cylinder to isolate the internal and external media. For the difficulty in smooth shrinkage of negative angle at the mouth during the forming process of aluminum alloy fuel tank end cap, according to the forming characteristics of the fuel tank end cap, it was proposed to adopt a special wedge mechanism to realize the one-time forming of lateral circumference, and by increasing the suction ribs to plan the flow direction of material at the mouth of end cap when closing, the rigidity of the part was improved while ensuring that it matched the shape and contour of cylinder clarity to meet the welding needs. Practice has proved that through the above process improvement and structure design of the closing die not only improve the dimensional accuracy and appearance quality of end cap products, but also reduce the difficulty of assembly and improve the production efficiency.
