Section bending machine

Types of section bending machines

A section bending machine, also known as a profile bending machine, is a piece of equipment used to bend various steel sections and profiles in different shapes, primarily in curved shapes. The machine is mainly used in industries such as construction, automobile manufacturing, and metal furniture production. There are three main types of section bending machines, which are as follows:

• Roll bending machines

Roll bending machines are the most commonly used machines for bending sections. They work by passing a piece of metal between three rollers, two of which are positioned above the metal and one below it. The two top rollers can be adjusted to allow for different radii of curvature. Additionally, one of the rollers is usually the one that is driven, which helps to feed the metal through the machine. Roll benders are ideal for bending metal sections, such as angle irons, flat bars, and square and round tubes.

• Induction bending machine

Induction bending machines are used to heat steel sections using an induction coil, which is then bent to a predetermined radius or angle using a bending head. Induction bending is ideal for creating large-radius curves in pipes, tubes, and other hollow sections. The process is highly accurate and can achieve precise bending angles. Additionally, it is suitable for bending high-strength and thick-walled materials.

• Press brake machine

The press brake machine works by pressing the metal between a punch and a die, which forms it into the desired shape. The machine is ideal for bending sheet metal, plates, and other flat metal sections into straight or curved shapes. The pressing force of the machine can be adjusted to accommodate different thicknesses and types of metal materials. The machine can be used for a wide range of applications, such as metal fabrication, signage, and architectural components.
