Bending - straining of a metal sheet to form an angle bend. The applied force stresses the metal beyond its yield strength, causing the material to plastically deform, but not to fail. Relatively simple numerical models, such as the Slab Method and the Upper Bound Method, were first used and many such models are implemented in the industry for practical design or regulation of forming processes. Under pressure, the rubber and sheet metal are driven into the die and conform to its shape, forming the part. Hu, in Mechanics of Sheet Metal Forming (Second Edition), 2002. These blanks are then exposed to blanking dies which cut the entire perimeter of the part, or to Then the other end is forced to strike upon the punch which is free or unfixed. Curling is a forming process that involves de-burring sheet metal to produce smooth edges. The stripper ring facilitates the removal of the formed cup from the punch. The performances of the models are proved by the numerical simulation of various sheet metal forming processes: hydroforming, deep-drawing and forming of the complex parts. 8.1.1 Deep Drawing Processes Chapter 8: Sheet Metal Forming Processes KSU -College of Engineering -IE Department 9 2) Single action deep drawing process Single-action drawingwith a draw cushion works the other way round the forming force is exerted by the slide above through the die and the blank holder onto the draw cushion in the press bed.

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. In this video we will discuss three basics to sheet metal forming. Bending along a straight line is the most common of all sheet forming processes; it can be done in various ways such as forming along the complete bend in a die, or by wiping, folding or flanging in special machines, or sliding the sheet over a radius in a die. ppt on Sheet metal process 1. It is customary to refer to a material below the thickness of 6.35 mm as a sheet and thicker materials as plate. Sheet metal operations not performed on presses. Hydroforming Of Sheet Metal . Sheet Metal Forming Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. It provides an expanded and more comprehensive treatment of sheet metal forming processes, while placing forming processes and die design in the broader context of the techniques of press-working sheet metal. Dies and Presses for Sheet Metal Processes 6. Mechanical working requires that the material may undergo “plastic deformation” during its processing. Hydroforming uses a rigid punch to push a sheet metal work piece into a rubber membrane. Roll forming of sheet metal is a continuous manufacturing process, that uses rolls to bend a sheet metal cross section of a certain geometry. Since the viscous medium help the flow of the sheet metal, the VPB forming process was able to reach large strain state.
