JB/T 5109-2001 Sheet Metal Bending Process Design Specification
3 cold metal stamping structural elements
3.1 General principles
3.1.1 Cold stamping design should be reasonable shape to be as simple as possible, the rules of symmetry and to save raw materials and reduce the manufacturing process, improve the mold life
Life, reduce job cost.
3.1.2 cold stamping of complex shapes can be considered divided into several simple stamping and then made the connection method.
3.1.3 The structure size limits given are determined according to the workpiece quality and economic efficiency.
3.2 blanking part structural elements
3.2.1 radius
Using a punching mold punching finished, its shape and the hole should avoid sharp corners clear, there should be an appropriate fillet. Usually fillet half
Radius R greater than or equal 0.5 times the thickness t, i.e. R≥0.5t (see Figure 1).
figure 1
3.2.2 punching size
Preferred circular. The minimum size and shape punching holes, the mechanical properties of the material and material thickness t about, no protective sleeve punch punching
The diameter d or a rim width specified in Table 1.
