1. Purpose of Bending
Sheet metals, pipes or sections are remodelled by various techniques in order to give angular or round forms to workpieces to be used for a certain purpose.
Figure 1 Bending
Due to its versatility, bending is applied in many manufacturing fields:
|
Folding: |
Fabricating short sections, channels, sheet-metal containers or cases as well as frames and supporting structures made of sections. |
|
Turning over: |
Fabricating edge stiffenings of containers or cases, preparing saddle joints. |
|
Flanging: |
Fabricating sheet-metal joints and edge deformations on containers, preparing saddle joints. |
|
Seaming: |
Fabricating sheet-metal joints on containers and pipes. |
|
Crimping: |
Fabricating sheet-metal stiffenings on containers and sheet linings. |
|
Rounding: |
Fabricating arched sheet metals for containers and pipes as well as curved sections. |
|
Rolling: |
Fabricating sheet-metal stiffenings on container rims, hinge joints, cylindrical cavities with flat sections for accommodating pins and spiral springs. |
