Due to the fact that the raw material for sheet metal processing parts is steel, this steel is subjected to external forces and heated for deformation during the process of cutting, shaping, and welding. Therefore, various issues, including deformation, may arise during the sheet metal processing. So, when deformation occurs in sheet metal processing, how should it be handled?
Possible Causes of Bending in Sheet Metal Processing:
1. Improper stacking or damage during transportation can cause the boards to deform.
2. Uneven heating can also cause deformation of the sheet material during the compression and extension of sheet metal processing.
3. After being heated, steel plates can deform during the cooling process if placed in a damp or wet area.
4. During bending, sheet metal processing tends to deform the holes in the workpiece. At this point, it is recommended to add a pattern of dimples on the top material sheet to increase friction and prevent slippage during bending.
Solution for Deformation in Sheet Metal Fabrication:
1. Generally, during the cooling process, the deformation of sheet metal processing is related to factors such as the type of quenching medium, cooling performance, and hardenability. At this point, adjustments need to be made by altering the viscosity of the medium, temperature, liquid surface pressure, the use of additives, and stirring. The higher the viscosity of the quenching oil, the higher the temperature, the smaller the elliptical deformation. In a static state, the deformation is minimal.
2. In heat treatment of forging, the deformation of sheet metal processing is related to the way it is placed. This requires: first, to hang vertically as much as possible; second, to place it vertically at the bottom of the furnace; third, to support it horizontally with two points, with the fulcrum located between one-third and one-fourth of the full length; fourth, to lay it flat on a heat-resistant steel fixture.
In summary, this article discusses the potential causes of deformation in sheet metal processing and the corresponding solutions. To effectively avoid the issue of deformation in sheet metal processing, it is crucial to pay close attention during the manufacturing process.
