Squeezing Operation In Sheet Metal

Bending causes no change in the thickness of the sheet metal.

Squeezing operation in sheet metal.

Coining dies create the part s shape by squeezing the metal under extreme pressure. There is a definite change in metal thickness. After that when the metal is going to be solid then the other die part is placed on the first die part and a compressive force is given to it. It is a metal removal operation.

Then the molten metal is placed to one part of the die. At first the die has to be heated. It is the cutting operation with the help of which holes of various shapes are produced in the sheet metal. Here the pierced metal is the final product then the operation is called as punching.

A simple round metal slug is placed into the die and forced to flow into a given shape by compressing it see figure 3. Cutting shearing operations in this operation the workpiece is stressed beyond its ultimate strength. During bending operation the metal on the inner side of the neutral plane is compressed and the metal on the outer side of the neutral plane is stretched. Squeezing is one of the most useful forming processes.

Sheet bending is defined as the straining of the metal around a straight axis. Sheet metal forming processes 34 2 3. Coins metal currency are created with the coining process. Blanking cutting or shearing of outside contours or shapes from sheetor strip stock.

It is similar to blanking only the main difference is that the hole is the required product and the material punched out from the hole is considered as a waste. It is the operation to produce circular holes on a sheet metal by a punch and a die. The piece cut out is the useful part. Coining also can reduce the metal thickness.

It leaves a lean edge on the piece of metal is sheared or cut. The sheet metal operations done on a press may be grouped into two categories cutting shearing operations and forming operations lecture 05. The die should be closed type die. Punching operation in sheet metal as explained above punching operation removes scrap from the larger piece of sheet metal.

As a result of punching a larger piece of sheet metal becomes the final product. For additional information visit.
