The die depends on the final require shape of product.
Thus the free or unfixed edge of the sheet metal piece is bent to make the forming process.
Stretch forming is performed on a stretch press in which a piece of sheet metal is securely gripped along its edges by gripping jaws.
Almost any shape that can be produced by other sheet forming methods can be produced by stretch forming.
When the die is support on the rotating table as shown in figure.
Most part defects such as splits and wrinkles occur in forming operations.
It is a type of bending operation in which a piece of sheet metal is fixed or held between two dies from one end as shown in the fig.
Then the other end is forced to strike upon the punch which is free or unfixed.
The stretch forming consists of gripper mechanism which is supported by hydraulic unit of holding the sheet metal.
Stretch forming aluminum extrusion duration.
Successful sheet metal forming relies heavily on the metal s mechanical properties.
In drawing a punch pulls the metal into the forming cavity so it forms the metal in tension.
Stretching stretch forming stretch forming is a sheet metal forming process in which the sheet metal is intentionally stretched and simultaneously bent to have the shape change.
All forming operations deform sheet material by exposing it to tension compression or both.
Stretch forming is performed on a stretch press in which a piece of sheet metal is securely gripped along its edges by gripping jaws.
Stretch forming is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large contoured parts.

Sheet is held by jaws or drawbeads at both the ends and then stretched by punch such that the sheet is stressed above yield strength.
The system having set of gripper is used to stretch the sheet metal.
