ABSTRACT
The design of a set of triming and punching mold. Through referring to information, first of all, I should analysis the process. Through process analysis and comparison, I use blanking and punching process. Through the blanking force, the top piece, and the discharge power to determine the model press. Further analysis of the stamping dies for processing the application to select the desired type of mold design. The moldwill be designed to draw upon the type of mold parts of thework expressed in the design process.
In the first part of the document mainly describes the development of stamping die, stamping die illustrate the importance and significance of this design, and then stamping parts of the process analysis, completed a process to identify programs. The second part of the nesting parts of the design plans to complete the calculation of the utilization of the material further edge blanking process of calculation and Die Design and Calculation of thework of some of the stamping equipment to provide a basis to choose. Finally, the main components of standard design and the choice of design-based mapping tool and provide a basis for forming mold, aswell as the assembly drawing to provide the basis of the size. Through the draw in front of mold design and assembly of the parts diagram Fig.
The design tells the structure of compound mold design andworking process. Reliable performance of the mold, smooth running, improved product quality and production efficiency, reduce labor intensity and production costs.
