With the continuous development of modern society, the sheet metal shell processing industry has also experienced rapid development. For any sheet metal part, there are certain processing steps. The processing steps of sheet metal shell are the key technology that sheet metal technicians need to grasp, and also an important process for forming sheet metal products. Do you know the steps for processing sheet metal shells? Below, the editor of Emma Technology Co., Ltd. will introduce to you:

Steps for processing sheet metal shells:

1. Drawing design:

Generally, customers provide drawings or samples, which are measured, designed, and unfolded by company engineering personnel to form sheet metal shell processing exploded drawings and assembly drawings and submitted to the production department for processing.

2. Laser processing:

Laser cutting machine can cut and cut materials such as carbon steel and stainless steel. By using laser cutting and cutting, the cross-section of the workpiece after processing is neat, smooth and beautiful, with precise dimensions. It has more advantages for workpieces with curved lines and is a sheet metal shell processing method that cannot be replaced by general CNC stamping.

3. CNC stamping:

The turret CNC punching machine is mainly designed for products with thin material thickness, generally suitable for materials below 2.5mm. The sheet metal shell has more holes for processing workpieces or requires special molds to process workpieces. When the batch size is large, using CNC punching has certain cost advantages.

4. Bending:

If most of the workpieces need to be bent and formed after being cut, the company has multiple computer bending machines, which not only have fast speed but also more accurate processing of sheet metal shells.

5. Welding forming:

After the workpiece is cut, it generally needs to be assembled into shape. There are various assembly methods, some of which are directly formed by non welding processes such as screws and rivets. Generally, the sheet metal shell of the mechanical shell is mostly formed by welding. The company generally adopts argon arc welding, butt welding, carbon dioxide welding, etc. After welding, the workpiece is polished and polished to make it more firm and beautiful.

5. Electrostatic powder spraying:

Electrostatic powder spraying is mainly aimed at carbon steel workpieces. In the sheet metal shell processing technology, oil and rust removal, surface adjustment cleaning, phosphating treatment, electrostatic powder spraying, high-temperature baking and other processes are generally carried out first. After treatment, the surface of the workpiece is beautiful, will not rust for several years, and has the advantages of low cost. The process of liquid paint is different from electrostatic powder spraying. Generally, it is suitable for large workpieces and has advantages such as convenience and low cost when it cannot be transported. Liquid paint is generally divided into two steps: primer is applied after the workpiece is processed and then painted.

6. Packaging and shipping:

Conduct a 100% inspection before packaging and provide inspection data. The shipping requirements and packaging methods have been confirmed by the customer's representative on site and are hereby recorded for further confirmation by the customer.

In summary, it is the step of processing the sheet metal shell. Every step of sheet metal shell processing is important, and any problem that occurs in each step will affect the processing quality of the product. Therefore, every step in the sheet metal shell processing process must be done well in order to produce qualified sheet metal shell products.
