Metal stamping is a complex process that can include many metal forming processes – punching, punching, bending and perforating. Blanking: This process is about cutting rough outlines or product shapes. This phase is about minimizing and avoiding Burr, which increases your part cost and extends the lead time. This step is used to determine hole diameter, geometry/taper, edge to hole spacing and insert the first perforation. Blanking – Metal stamping design Bending: When you design a bend in a metal stamping, it is important to allow enough material – to ensure that the part and its blank are designed so that there is enough material to perform the bend. Some important factors to remember:
If the bend is too close to the hole, it may be deformed.
The width of the notches and tabs and the grooves should be at least 1.5 times the thickness of the material. If they are made smaller, they are difficult to form because the force exerted on the punch causes them to break. The radius of each corner in the blank design should be at least half the thickness of the material.
To minimize the number and severity of burrs, avoid sharp corners and complex cuts as much as possible. If these factors cannot be avoided, be sure to pay attention to the burr direction in the design to take these factors into account during the stamping process.
Imprint: This action is when the edge of the stamped metal part is crushed or broken; this creates a smoother edge in the molded area of the part geometry; this also adds extra strength to the local area of the part. This can be used to avoid secondary machining such as deburring and grinding.
