Abstract：

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.
