Manufacturing and construction industries of today heavily rely on operations that can shape metal sections into precise forms. This is possible by section bending machines. For bending beams, angles, channels, or flat bars, a section bending machine is an invaluable tool used for shaping intricate curves and bends within metal structures.
In the article, we will explain the definition of section bending machines and their workings, classification, application, and merits. Also, we will discuss the unique features to look for when selecting one, and present how these machines are applied in different industries.
What is a Section Bending Machine?
A section bending machine is also known as a section bender or roll bender, and refers to a specific machine that bends different profiles of metal sections like beams, angles, channels, and other structural shapes. With this machine, it is possible to obtain both simple and complex curves with high accuracy in radius and angle.
Such machines progressively impose pressure to a metal piece using a set of rollers, bending the material without distorting it or inflicting any form of significant damage. Unlike manual bending techniques, section bending machines offer greater flexibility with regards to the extent and control of the bending process which makes them best suited for the creation of complex shapes that require a high level of accuracy.
Operation of a Section Bending Machine?
The basic operation of a section bending machine uses three rollers which are set in a triangular position. The machine usually consists of:
1. Top Roll: The top roll serves the purpose of feeding the material into the machine and it guides the piece throughout the process. This roll applies a downward force to the metal section to assist in its positioning.
2. Bottom Rolls: Typically, there are two bottom rolls, one is movable and the other is static, the piece can be set to vary the radius of the bend. The fixed roll does not move, while the moveable one can be adjusted to change the amount of pressure applied to the material. The additional curvature is controlled through the moveable bottom roll.
3. Adjustable Parameters: Machines of this type usually have automated system which allows the operator to set the desired speed, position, and force to be applied to the workpiece in order to produce an accurate bend. After the metal piece is put in between the rolls, the press applies pressure and rotation to shape the material as required. The operator is able to set the degree of curvature needed by adjusting the rolls and the height of the bend.
Classification of Section Bending Machines
In general, a machine's purpose is defined by the sector it caters to. Similarly, section bending machines are categorized based on their shape and functionality. Broadly, these machines are classified into Horizontal Section Bending machines and Vertical Section Bending machines.
Horizontal Section Bending Machines : Horizontal Section Bending Machines are designed with the rolls positioned laterally. The material is placed into the machine, and the rollers start bending the sections around the horizontal axis. This machine is best for heavy duty and larger sections. These machines are used most frequently in industries that require construction and shipbuilding.
Vertical Section Bending Machines : For vertical section bending machines, the rolls are set standing up allowing the material to be fed in vertically. These machines are great for bending small sized sections and lighter materials. This machine best suited for accuracy and compact bends in narrow sizes.
Universal Section Bending Machines : These types of machines are broad in scope as they can work on different materials and sections. Things ensures step bending of more complex shapes and angles with very fine precision. Universal section bending machines are usually made with a cut with more than two rollers and can work on much deeper sections. (read)
