What Is a Bending Machine?
A bending machine is a generic term for processing machines used to bend pipes, metal plates, and angle bars.
Bending machines are often specialized machines depending on the workpiece to be processed. There are many types of bending machines available for workpieces of various sizes, ranging from small tools that bend pipes manually to large processing machines that can be programmed and automatically processed using electric, hydraulic, or other actuation methods.
This section describes small bending machines used primarily as tools.
Uses of Bending Machines
There are many different types of small bending machines, each of which is divided according to the type of workpiece to be processed and the processing method.
Manual bending machines are tools used in field environments where there is no working power source. They are used for bending thin pipes, reinforcing steel wire rods, steel plates, and thin aluminum sheets.
Motorized bending machines are used for bending and cutting operations on rebars and angle bars.
Hydraulic bending machines are used primarily for bending pipes. Some have a combined power source, such as the electro-hydraulic rebar Bending Machine cutter.
How to Select Bending Machines
Many bending machines are specialized tools for specific applications or types of workpieces, and the points to consider in selecting bending machines differ for each tool.
- Pipe bending machines
Many bending machines for pipes with thin outer diameters are small and bend by pushing and closing two levers by hand-like scissors.Hydraulic pipe bending machines are used for bending pipes with large outside diameters, thick-walled steel pipes, and stainless steel pipes that are difficult to process with small manual Bending Machines, as well as for bending pipes with large bending radii. It is necessary to select a suitable bending die according to the pipe’s outer diameter and bending radius.
- Bending machines for rebars
Bending machines for rebars are available in manual, electric, and electro-hydraulic types. They are selected according to the availability of a power source at the work location, the number of pieces processed, and work efficiency. There are portable, hand-held Bending Machines as well as stationary bending machines that are placed at a fixed work location for processing. There are also tools that can cut, such as electro-hydraulic rebar Bending Machine cutters. - Thin plate bending machines
This is a bending machine for thin steel and aluminum plates. Selection must be made after confirming the size and thickness of the plate that can be processed.
