Edge Rolling Parts
Edge rolling, we can also call it bending roll round, which is a method to put the sheet metal bending into the nearly closed cylinder forming. It belongs to a kind of metal cold bending.

Edge Rolling Parts Design
For thin soft materials (t<=0.5)
A: When the inner diameter of the enclosed circle ∅d<=4.0, the 4-step pressure arc forming method is generally used for the enclosed circle, as shown in Figure 44-1.
B: When the inner diameter of the inner circle is 4. 0<∅d<=15.0, you can use either the 4-step arc forming style for wrapping or the mandrel forming style for wrapping
C: When the inner diameter of the inner circle ∅d>15.0, the mandrel forming method is generally used.
D: If the product requires a high centroid dimension, for the inner diameter of the inner circle ∅ D >3.0, we recommend using the mandrel forming method because it can make the circle a little rounder.
For thick hard materials (t>0.5)
For thick hard materials, if the 4-step pressure arc forming method is used to wrap the circle, it is generally difficult to wrap it around as the centrality is poor.
Because the material's yield strength is high, it is difficult to turn over to roll the material; And thin soft material's yield strength is low, the shape is easy to be rolled when making the formation, therefore, for thick hard material forming, we recommend to choose mandrel forming method to wrap. As shown in figure 44-2
