A bending machine for metal sheets, also known as a sheet metal bending machine or sheet metal brake, is a device used to bend or shape metal sheets into desired angles or forms. It is commonly used in various industries such as manufacturing, fabrication, construction, and automotive.
There are different types of bending machines available, including manual, mechanical, hydraulic, and CNC-controlled machines. The specific method of bending and the level of automation depend on the type of machine being used. Here are some common types:
1. Manual Bending Machines: These machines are manually operated and typically used for light-duty bending tasks. They usually have a hinged bending beam and a handle that the operator uses to apply force and bend the metal sheet. Manual bending machines are simple and affordable but require physical effort and may not offer high precision.
2. Mechanical Bending Machines: Mechanical bending machines use mechanical mechanisms, such as gears and levers, to apply force and bend metal sheets. These machines are more powerful than manual ones and can handle thicker and larger sheets. They offer increased precision and control over the bending process.
3. Hydraulic Bending Machines: Hydraulic bending machines utilize hydraulic systems to generate and control bending force. They are capable of bending thicker and heavier metal sheets with high accuracy. Hydraulic machines offer adjustable speed and force settings, making them suitable for a wide range of applications.
4. CNC Bending Machines: Computer Numerical Control (CNC) bending machines are the most advanced and automated type. They feature a CNC system that controls the bending process, including tooling setup, positioning, and bending parameters. CNC machines offer precise control, programmability, and the ability to handle complex bending tasks. They are often used for high-volume production and require minimal operator intervention.
