What is the process standard for flanging of metal stamping parts?

Today, Xiaoshuo and everyone will learn about the 'flanging process' of the mold of metal stamping parts. What is the flanging process? We use pre-processed metal punching holes or partial hole-shaped wool (sometimes not pre-processed holes), relying on the deformation of the material to turn into a vertical edge along a certain curve, which is called 'flanging'. Metal stamping circular hole flanging and outer edge flanging. Because it is formed by stretching the material, its forming is mainly limited by the elongation of the material. The flanging is mainly used for riveting, through hole, tapping and other functions. The die and calculation formula of metal punching round hole flanging and related process requirements data are as follows: Formula: du003d0.5~0.6T; the value of d is inversely proportional to H. When the value of d is small, the value of H is large. Du003dD1+(D-D1)u003dD1+1.3T; In order to ensure the verticality of the flanging D, in general, D≤D1+1.3T. Hu003d+0.43R+0,72T; Flanging height H (depending on the volume of flanging metal) is usually 1.7T~1.9T. Lu003d+2.5T; M is the thread specification. In the formula, d is the diameter of the pre-punched hole, D1, the inner diameter of the flanging hole/punch punch D2, the diameter of the flanging vertical edge (calculated according to the center layer) D, the outer diameter of the flanging hole H, the height of the flanging hole R, the inside of the flanging The radius/outer radius of the die L-the center distance of the flanging hole and the edge distance T-the thickness of the material. The flanging data of the small threaded hole is as follows: Hardware stamping process requirements: The height of the metal stamping flanging hole is H≥3P; P is the thread pitch. The hole distance tolerance of the same plane of the flanging is ≥±0.15. It is not recommended to use Tu003d1.5mm stainless steel for M3 flanging, and Tu003d2.0 stainless steel for M4 flanging. When the aluminum plate flanging and tapping, the force that the thread can withstand should be considered. There are two types of outer flange flanging: convex contour flanging and concave contour flanging; flanging with convex contour is also called compression flanging, and flanging with concave contour is also called elongation flanging. Note: R is the corner radius of the part after flanging; b- the difference between the radius before flanging and the radius after flanging; R+b, Rb is the corner radius of the part before flanging (blank) if there is hardware For questions about the process standard of stamping parts flanging, please contact [Precision].
