Bending machines are a specialized class of industrial-level automated machine tools built for shaping base metal in a solid-drawn way without the use of welding works and with repeatable accuracy. Used in the manufacturing of products made from metals of all types, they can be used for both hot and cold bending.
These bending tools are considered vital to modern metalworking, and play a vital role in the automotive, industrial manufacturing, and power sectors. Throughout all of the various utilizations, different types of bending technologies are required as each type of metal has different mechanical properties. In this post, we’re going to explore the different types of bending machines, as well as provide more information on the four bending machine manufacturers featured on The Equipment Hub’s marketplace.
Types of Bending Machines
Bending itself is a general manufacturing process that encompasses a number of techniques designed to manipulate different types of metal. At the most basic level, there are three primary types of bending performed by machines.
- Air bending utilizes a punch and die arrangement, where the punch pushes the material down against the die in order to create the bend. While it is a less precise method, it has the advantage of being useful with various materials as well as flexibility in the placement of the die and punch in order to allow more versatility with fewer tool changes and thus increased productivity.
- The bottoming method cannot create U-shaped openings but allows for smaller radii and increased force over air bending with increased accuracy. However, the flexibility of angles it can create relies upon more tool changes, making it a less popular method.
- Coining utilizes a much stronger force than air bending, resulting in permanent deformation and little spring back with very high levels of precision. This makes the process cost-prohibitive and less popular than other methods.
There are a number of other bending methods that have evolved over time, including three-point bending, folding, wiping, rotary bending, roll bending, and joggling.
Common Types of Bending Equipment
In order to accomplish these types of bending processes, the INNOPROM International Metalworking Exhibition defines 8 types of bending equipment popular on the market today.
- Sheet bending presses, automatic and mechanical
- Multi-functional equipment for laser-cutting, forming and bending
- Rotary (rolling press) sheet bending machines
- Hydraulic/electromechanical folder machines
- Hydraulic/electromechanical profile bending machines
- Pneumatic bending equipment
- Pipe or tube benders
- Machines for bending wire and fittings
These machines can be used in the production of other machinery, aircraft and ship construction, construction materials, pipe construction, architectural applications as well as in the production of furniture and other interior elements, and in the manufacture of signage support structures for use along highways and roadways.
