Stamping die design guidelines

Stamping die design is the preliminary phase in stamping tool and die making and is carried out as soon as the component design is finished. The stamping die drawing stage is extremely critical as a good quality stamping die blueprint can generate accurate stamped components which can run for an extended time with less maintenance. Designing the carrier within the width of the part minimizes the need for additional material to be included in the process Carrier width should be at least 2 times the material thickness Larger dies may require larger carrier widths to facilitate pushing the strip through the die A Stamping Die Design Procedure for Part Springback and Compens ation E. Esener , M. Yenice , M. Firat* 1 Mechanical and Manufacturing Engineering Department, Bilecik S.E. University, 11210 It is possible to stamp a blank width Aequal to material thickness T; however, this will contribute to increased tool downtime. The smallest blank width that can be stamped is 0.10 mm x 0.05 mm thick material. The smallest recommended pierce diameter is 2 x T. The size of an inside or outside corner radius is directly related to tool cost. Recommended inside bend radius for sheet metal parts should be equal to material thickness. For hard materials (Stainless steel, CRCA), an inside bend radius equal to 0.65 times of sheet thickness is also enough. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. flexibility. By using standard vee-dies, cost savings can be realized through economical set-ups and run times on small lots and prototypes. In addition to these considerations, using the following guidelines will increase the manufacturability of designs for press brake forming. Dimension the part in a single direction wherever possible. Metal stamping is a metalworking process that employs tool and die sets and specialized presses to form metal sheets and coils into net shapes. It is a cold working manufacturing method, meaning it typically creates the desired parts and products from room temperature materials in room temperature conditions. To make your stampings as functional, efficient and economical as possible, the following guidelines are recommended.

Holes: Minimum hole diameter should be equal to or greater than 1.2 times the material thickness. A stamping die is a dedicated precision fixture that bends, forms, stretches and cuts metal to the desired shape. The die itself is mounted into a machine called a press. Makes sense; the machine presses the metal into shape! There are two basic types of dies; those that cut and those that form. Some do both. Cutting by the way is a loose term Die Design. Die design is the preliminary stage in stamping die manufacturing once the product design is completed. Die design stage is very critical. A good die design can produce accurate components which can run for long time with less maintenance. Die design involves deciding the required stamping operations, basic layout, machining Abstract Nowadays, the casting structure of stamping dies is
