Explaining common pitfalls in metal press molding prototypes and designs by shape! Includes easy-to-understand illustrations! *Many achievements in automotive parts and construction machinery molds.
In "Points for Designing Metal Press Parts That Don't Fail," we introduce common failure cases and their solutions in the manufacturing and design of 3D-shaped press parts, such as deep drawing.
Kagawa Manufacturing, a press prototype workshop boasting skilled processing techniques, illustrates three types of shapes: "pointed shapes," "warped shapes," and "drawn shapes."
~For those who are struggling with issues like these~
■ Want to minimize thickness reduction
■ Want to eliminate wrinkles (buckling phenomenon) caused by compressive stress
■ Have traces from the number of processes remaining as wrinkles
【Failure Cases】
■ Pointed Shapes
In shapes with a peak, such as triangles, the stretching of the plate is concentrated, leading to easy crack formation, and there is a high risk of significant thickness reduction, making it difficult to secure the minimum required thickness.
■ Warped Shapes
The circumference dimension on the bottom side is longer than that on the top side, and the excess difference appears as wrinkles or overlaps in the bottom part of the top side. This shape is unsuitable for the mating surface with counterpart parts.
■ Drawn Shapes
To secure the outer dimensions after drawing, the material dimensions must be increased, but a large number of processes are required to draw the cylindrical part, resulting in traces from the number of processes remaining as wrinkles.
