Changing the appearance of metals due to the force applied to the metal is called bending.
☑️ Methods of bending metal sheets
There are different methods for bending all kinds of steel sheets, and the choice of each method depends on several factors such as the thickness of the sheet, the type of metal, the bending angle, the required accuracy and the available equipment. Here are some common methods for bending sheet metal:
🔘 Hand bend
The manual bending method is suitable for thin sheets with small angles. In this method, tools such as hammers, clamps, bending pliers, and mandrels can be used, and the accuracy of hand bending depends on the skill and experience of the person.
🔘 bend with the presses
Press bending is suitable for thicker sheets with more precise angles. In this method, there are different types of press devices such as mechanical, hydraulic and pneumatic presses. The accuracy of bending with a press machine depends on the type of machine and its settings.
🔘 Bending with the bend machine
Machine bending is suitable for long sheets and complex angles. There are different types of bending machines such as manual, electric and hydraulic bending machines. The accuracy of bending with this device depends on the type of machine and its settings.
🔘 bend with thermal methods
In thermal bending, heat is used to soften the metal and bend it. There are different methods such as flaming, furnace heating and electrical induction. This method is suitable for bending thick and hard sheets.
Preparation of equipment needed to bend metal sheet
Preparing the equipment needed for bending the metal sheet includes the following steps:
▪️Marking the bend lines
▪️Cutting the metal sheet
▪️Placing the metal sheets between the clamps
▪️Bending the metal sheet with a hammer
p>▪️Troubleshooting the bending process
▪️Re-examining the bending angle
