What causes the deformation of sheet metal parts?

Many items we see in our daily life are actually made of sheet metal processing, ranging from mobile phones, mechanical parts of some sizes, accessories, etc., to billboards at bus stations, refrigerators, lockers, etc. They are all sheet metal parts. However, in the process of sheet metal processing, sometimes for various reasons, sometimes the sheet metal processing parts will be deformed. So do you know what causes the deformation of sheet metal parts? The reasons for the deformation of sheet metal parts are as follows:
1. Deformation of raw materials
Deformation of raw materials, if the raw materials of sheet metal processing parts are stacked in the wrong way or subjected to impact during transportation, the deformation of the sheet will be caused.
2. Uneven heating
Uneven heating of sheet metal parts can also cause deformation of the sheet when it is compressed and extended.
3. Improper cooling placement
If the heated sheet metal parts are placed in a humid or watery place during the cooling process, they will also be deformed.
4. Hole deformation occurs when bending
Sheet metal processing parts are easy to deform the holes on the workpiece when they are bent. At this time, pitting grids should be added to the top sheet to increase friction and prevent the workpiece from slipping during bending.
To sum up, we can see that the main reasons for the deformation of sheet metal processing parts are raw material deformation, uneven heating, improper cooling placement, and hole deformation during bending. Therefore, when we process sheet metal More attention is needed to avoid the above problems and present better products to customers.
