摘要：

摘要：斜楔机构是一种将压力机上滑块的上下垂直运动转换成水平或倾斜方向运动的机构。液压斜楔机构具有结构紧凑、工作角度不受限、压力中心不偏移等特点。介绍了普通机械式斜楔机构与液压传动式斜楔机构的结构及工作原理，对比分析了液压传动式斜楔机构的优点，简要总结了液压传动式斜楔机构的型号规格及选型步骤；并以某著名汽车品牌的整形局部弯曲工序模具为例，说明了液压斜楔机构在汽车冲压模具中的应用优势。结果表明，相对于普通机械式斜楔机构，液压斜楔机构可有效提高冲压精度、降低模具和冲压成本、缩短模具设计周期，液压斜楔机构在结构复杂且要求模具紧凑的情况下，具有更好的实用性并可获得更高的冲压质量。

Inclined wedge mechanism is a kind of mechanism which can convert the vertical movement of press slide into a horizontal or inclined movement. Hydraulic inclined wedge mechanism has the characteristics of compact structure, unlimited working angle, constant pressure center etc. The structure and working principle of the mechanical and hydraulic inclined wedge mechanisms were introduced respectively, the advantages of hydraulic inclined wedge mechanisms were compared and analyzed, and its type and selection procedure were summarized briefly. Furthermore, taking the reshaping and local bending die of a famous automobile brand as an example, the application advantage of hydraulic inclined wedge mechanism in automobile stamping die was illustrated. The results show that the hydraulic inclined wedge mechanism improves the stamping accuracy, deduces the cost of die and stamping, and shortens the die design time. And it has good practicality and high stamping quality when the die structure is complex and required to be compact.
