Squeezing operation in sheet metal.

It is a cut in a straight line across a strip sheet or bar. Sheet metal forming processes 34 2 3. As a result of punching a larger piece of sheet metal becomes the final product. Cutting shearing operations in this operation the workpiece is stressed beyond its ultimate strength.

It is a metal removal operation. Blanking piercing notching trimming. Shearing operation diagram learn mechanical 3 powder metal forming. The sheet metal operations done on a press may be grouped into two categories cutting shearing operations and forming operations lecture 05.

Shearing for curved blades. It is a metal forming operation in which the straight metal sheet is transformed into a curved form in bending operations the sheet metal is subjected to both tensile and compressive stresses during the operation plastic deformation of the material takes place beyond its elastic limit but below its ultimate strength. For additional information visit. Coining dies create the part s shape by squeezing the metal under extreme pressure.

In this operation the metal sheet is in cantilever position and a punch coming from the top exerted the force on the cantilever position of the sheet. Punching operation in sheet metal as explained above punching operation removes scrap from the larger piece of sheet metal. Coining also can reduce the metal thickness. In this operation a sheet metal workpiece is placed or kept between two dies from one end.

Squeezing in this operation the metal is squeezed within the cavity of the die and the punch to attain the desired shape. A hem is an edge or border made by folding hems are commonly used to reinforce an edge hide burrs and rough edges and improve appearance. Blanking cutting or shearing of outside contours or shapes from sheetor strip stock. There is a definite change in metal thickness.

Shearing is just a cutting operation of the metal sheet. The piece cut out is the useful part. The major operations of sheet metal are. Coins metal currency are created with the coining process.

A simple round metal slug is placed into the die and forced to flow into a given shape by compressing it see figure 3. And the punch is hit at the other end of the sheet producing a shearing effect. It leaves a lean edge on the piece of metal is sheared or cut.
