THE FONUDATION PUNCH HLOES FALL THE MATERIAL CURVING MOLD THE DESING
ABSTRACT:The topic of this design is the foundation punch holes fall the material to be curvingforming process and die design. The requirement,content and direction of the design of the stamps forming plate parts are embodied on this stamping die design. The designer’s foundation knowledge of the stamping die design is reinforced and is able to design more complex stamping die through the design.
The design of the use of the punch holes fall the material curving forming process and die design of the basic knowledge, First, we analyze the shape of workpiece forming process and die structure of the parts quality. Introduced The foundation punch holes fall the material curving mold design to the main points of attention, through the process of parts for analysis, to determine parts of the forming die with two sets of molds are the punch holes fall the material true thing superposable die and one time form the mold curving. Embarks from the control workpiece size precision, To the foundation punch holes fall the material bending die of the main dimensions of the theoretical calculation to determine the size of the working parts. Parts from the mold design to the processing technology as well as the assembly process, such as described in detail, and the application of CAD for the design of the important parts.
