One of the processes that sheet metal fabricators need to be aware of is the heat deformation process, which generally requires good heat treatment in order to avoid product deformation. So how should sheet metal heat deformation be carried out?
Sheet metal heat distortion treatment methods
Firstly, during the insulation process, the residual stress of the sheet metal processing will be released and deformation will occur, and the self-weight of the parts will also lead to deformation.
During the cooling process, as the cooling speed of different parts of the part is different, thermal stress will be formed and the part will be deformed. Even if the cooling rate is the same, the cooling is always faster on the surface and always slower on the inside. How sheet metal fabricators carry out thermal deformation treatment
Secondly, the product shrinks during low temperature tempering and the amount of shrinkage is proportional to the supersaturated carbon content.
When heated at room temperature – 200°C, expansion occurs. However, as the metal decomposes near 200°C, the expansion does not change much. In conventional heat treatment, the main cause of part shape change is the thermal and phase change stresses that occur during the heating and quenching heat treatment. If the heating rate is too fast, the part is too large compared to the heating furnace and each part is at a different temperature, the sheet metal will be thermally distorted.
If you use the console on a daily basis, regular maintenance is required to ensure product performance. This not only extends the life of the product, but also ensures a safe operating environment. Simple, convenient and functional consoles are widely used at work. Firstly, if problems arise, you need to deal with the components in good time, for example by checking for frequent rusting. Problems found can affect the normal use of the system later on.
Then clean the console on time, as dust can affect the proper use of the console, so regular cleaning can extend the life of the console.
Finally, you need to polish and wax the console in good time. If the candles are dry, use a dry sponge or rag for wiping. This makes the console brighter and cleaner.
