Squeezing operation in sheet metal.

In this operation a sheet metal workpiece is placed or kept between two dies from one end. Coining a squeezing operation usually performed in a closed die in which the metal is forced to flow and fill the shape and profile of the die. It is a metal removal operation. The mechanical cutting of materials without the information of chips or the use of burning or melting for straight cutting blades.

Coining dies create the part s shape by squeezing the metal under extreme pressure. Shearing for curved blades. A shearing b bending c drawing and d squeezing shearing. Blanking piercing notching trimming.

Sheet metal joints 1 hem. And the punch is hit at the other end of the sheet producing a shearing effect. Cutting shearing operations in this operation the workpiece is stressed beyond its ultimate strength. Shearing is just a cutting operation of the metal sheet.

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. Punching operation in sheet metal as explained above punching operation removes scrap from the larger piece of sheet metal. Coins metal currency are created with the coining process. It is a cut in a straight line across a strip sheet or bar.

As a result of punching a larger piece of sheet metal becomes the final product. It leaves a lean edge on the piece of metal is sheared or cut. There is a definite change in metal thickness. Squeezing in this operation the metal is squeezed within the cavity of the die and the punch to attain the desired shape.

Blanking cutting or shearing of outside contours or shapes from sheetor strip stock. Shearing operation diagram learn mechanical 3 powder metal forming. Sheet metal forming processes 34 2 3. Coining also can reduce the metal thickness.

A simple round metal slug is placed into the die and forced to flow into a given shape by compressing it see figure 3. 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. 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.
