Press working operations/Sheet Metal Operations PDF: The operations performed on the sheets to get the required shape is called sheet metal operations.In the last article, we had discussed about 5+Types of dies which are performed on Sheet metal to get the required shape.
First go through it so that you can understand the current topic must effectievely.
Note: Download Press working operations PDF at the end of the article.
Around 10 Sheet Metal Operations can be performed on the sheet and they are as follows.
- Deep drawing
The detailed info about (5-10) sheet metal operations are presented at the end and the rest (1-4) are covered below.
By physical removal of the material from the sheet, if the required shape of the component is obtained called as cutting or shearing operation.
Press working operations/Sheet Metal Operations:Here, Punching and Blanking Comes under Cutting or Shearing Operations whereas Deep drawing and bending come under Forming Operations.
Sheet Metal Operations-Cutting Operations:The cutting operations which come under Sheet Metal Operations are 1.Punching Operation 2.Blanking Operation For both punching and blanking operations, the punch and die combination will be used as tools.
- Punch Size < Die Size(Basic Requirement)
- Punch Size = Hole Size. (Needed)
- Clearance → Die.
- Shear → Punch.
- Die Size = blank Size.
- Clearance → Punch.
- Shear → Die.
- Automobile industries.
- Kitchen appliances.
- Aerospace industries.
- Mass production of sheet metal components.
Sheet Metal Operations-Forming Operations:The Forming operations which come under Sheet Metal Operations are
- Straining sheet metal around a straight axis to take a permanent bend is called Bending Process.
- Metal on the inside of a neutral plane is compressed, while metal on the outside of a neutral plane is stretched.
- V bending
- U bending
- Edge Bending
|V bending||Edge Bending|
|Performed with a V-shaped die||Performed with a Wiping die|
|V-Dies are simple and Inexpensive||These dies are complicated and costly.|
|It is for Low Production.||It is for high Production.|
- Drawing board clip, tube light frame, air conditioning duct, etc.
- Automotive industries.
- Delivery of fluids, either gaseous or liquid, in a process plants in Containers.
Explanation of remaining Cutting operations:
- Blanking: It is the operation of cutting a flat shape from the sheet metal is called Blanking operation.
- Punching: It is an operation of making holes of different shapes from sheet metal and is called a punching operation.
- Notching: It is an operation by which metal pieces are cut from the edge of a sheet or blank is called a Notching operation.
- Perforating: It is an operation by which multiples holes of smaller size are made in sheet metal called perforating operation.
- Trimming: It is a process of removing unwanted material from the surface of the workpiece called a Trimming operation.
- Shaving: The process of removing a thin strip of metal from the blanked part is called as shaving. It can be done after trimming only so that the strips which are not removed by the trimming process are removed by the shaving process.
- Slitting: It is an operation of making incomplete holes in a workpiece called as slitting operation.
