What is steel sheet cutting?
Black sheet or iron sheet is considered as the raw material in the production of steel products. In order to be able to use them for different purposes, they must be cut to make it possible to transform into the desired product. Cutting steel sheets and turning them into smaller pieces using mechanical and manual methods is called iron sheet cutting.
A variety of sheet cutting methods
Knowing different methods of steel sheet cutting helps us to choose the best option when choosing, according to features such as sheet thickness, sheet price, accuracy and quality of the final product, and speed of work.
< p>turning method Cutting of steel sheets using the lathe method is mostly used in the automotive industry and this method is one of the traditional, hot and of course mechanical methods. Iron sheet cutting is done by the corresponding machine with high precision. Grinding method This method is also similar to the above method in the categories of traditional, hot and mechanical methods and is used to cut sheets that are important for the quality of the top surface of the sheet. The blade of the grinding stone rotates and smooths the surface of the metal. Punch method Punching is another traditional method used in cutting steel sheets, and it is also referred to as a cold and mechanical method. The punching method is mostly used for strong metals and by applying a pressure of about a thousand tons, it cuts the sheet. Also, punched sheets are available in the market.Sanding method
The sanding method is very similar to the grinding method and they are done in almost the same way. The only difference between them is that in this method, the type of sandpaper must be selected according to the part that is cut.
threading method
Threading is another traditional method that works using milling, rolling and forming machines, and is less used today.
Electrode method
Making holes in metals and cutting is another application of electrodes in industry. Each electrode has its own application and should be used according to the need. This method is one of the warm and modern methods.
Scissor method
It is one of the old and cold methods, which is used to cut metal sheets with very low thickness. For manual scissors with a thickness of about 1.5 mm, scissors with a thickness of about 6 mm and lever scissors with a thickness of about 5 mm can be considered.
Now it is necessary to know that there are many main methods for shaping these metals: Cutting using cutting dies water jet laser guillotine plasma air gas Flame cutting wire cutting Milling Electric discharge
Accuracy and quality and cost estimation: If you care about the appearance of the sheet after cutting, use the waterjet method. If you want to produce less waste, use the laser or waterjet method. If you want to have regular and precise cuts, use the waterjet or laser method. If costs are important to you, use the air gas method. If quality is not important to you, use the plasma method.
During the cutting process of black sheet and other types of sheets, various factors occur in the material, including the following:
Deformation and high plastic strains, especially in the slack distance
High strain rate due to high blade speed
hard work
Initiation of the crack and its expansion until the final rupture: The crack first starts from the two edges of the blade, and when our damage criterion reaches its critical value, the crack begins to grow and moves forward in the gap between the two blades. .
Temperature effects: The high speed of the blade used in processes such as guillotine leads to high strain rates and increased temperature due to the loss of plastic work in the cutting area.
