Processing of sheet metal plate in factory

“Sheet metal is used in automobile and truck (lorry) bodies, airplane fuselages and wings, medical tables, roofs for buildings (architecture), and many other applications.”according Wikipedia .We will talk about the processing of sheet metal plate in Factory as below.

1. Blanking: according to different drawings, there are different blanking methods, mainly including CNC punch and laser cutting. Let’s start the blanking process one by one.

Firstly, Large burrs may appear on the edge of the work piece processed by NC punch.

Secondly, The laser processing section is flat, which is very suitable for the processing of special-shaped work pieces. After blanking, paying attention to the necessary grinding of edges, corners and burrs to facilitate the positioning during bending and ensure the consistency of the size of the same batch of products.

2. After blanking, enter the next process. Different sheet metal parts have different processing procedures. Processes include bending, riveting, spot welding, etc.

A. Press riveting: select the die according to the height and size of the stud, and ensure that the surface of the stud and the sheet metal part must be flush when using the press.

B. Bending: select the bending tool and bending groove with corresponding thickness according to the size of the required bending material on the drawing.

C. Spot welding: in order to weld firmly, bump welding shall be made on the connection between the work piece and the work piece, and the welding position shall be accurate at the same time.

According to the processing procedure, pay attention to

A. The parts with convex hull and segment difference shall be processed first with the die, so as to avoid interference after processing in other processes, and the next processing cannot be completed.

B. The bending sequence must be determined first. The general rule is from inside to outside, from small to large, and from special to ordinary. 3. After spot welding, there will be weld scars on the surface of sheet metal parts, which should be treated with a grinder.

3. After the bending and riveting process is completed, the workpiece shall enter the riveting process.According to the assembly and packaging process.

According to the processing procedure, pay attention to as below:

  1. The parts with convex hull and segment difference shall be processed first with the die, so as to avoid interference after processing in other processes, and the next processing cannot be completed.
  2.  The bending sequence must be determined first. The general rule is from inside to outside, from small to large, and from special to ordinary.
  3.  After spot welding, there will be weld scars on the surface of sheet metal parts, which should be treated with a grinder.
