Piercing Operation In Sheet Metal

Piercing is the operation of punching holes in the sheet metal.

Piercing operation in sheet metal.

In other words piercing operation produces an extruded hole in sheet metal. Piercing in sheet metal. One is cutting and the other is bending. There are two main operations of the sheet metal fabrication process.

The punch used in the piercing operation is usually bullet shaped. Piercing is the process in which desired shape holes are produced in a piece of sheet metal without eliminating any material from the sheet or removing a very small amount of material as shown in the figure. The process and machinery are usually the same as that used in blanking except that the piece being punched out is scrap in the piercing process. Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal.

It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools. Blanking piercing and punching comes under sheet metal cutting operations. Both punch and die are also applied in this operation.

It is one of the most extensively used processes throughout die and sheet metal work. The nibbling process cuts a contour by producing a series of overlapping slits or notches. Piercing operation produces an extruded hole or slot. In other words piercing is a combination of cutting and forming operation.

Sheet metal fabrication is a metalworking process to cut and form sheet metal into the desired shape which can be useful for end applications. As a result of applied force from a piercing tool sheet metal starts tearing and produces an extruded hole or slot. In case of piercing or punching the material which is cut out from the sheet metal is scrap and the reining material is the actual part. As explained in the above image.

Notching is a piercing operation that removes material from the edge of the workpiece. Metal cutting is a process used for separating a piece of material of predetermined shape and size from the remaining portion of a strip or sheet of metal. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot.
