钢管冲孔、压凹楔块式组合模
Wedge Combination Die of Steel Tube Punching and Recessing
According to the process features of the part, two wedge mechanisms are designed for a set of mold. They are conjugate wedge mechanism for punching holes and floating wedge mechanism for stamping concave. The layouts of the two wedge mechanisms in the molds, the relationship between the parts and the action principle of the wedge mechanism are introduced.
