Rod Bending

Rod bending is a broad term that applies to forming machine tools that assemble bends on any workpiece.

Rod bending tools range from small, handheld devices, to automated machines. Bending tools are made to adjust the bending angle by reference, stroke measure or angle measure. There are several classification of bending tools.

Established bending tool types are: Standard Bends, U-Bending, Offset Bending, Edgewise Bending and Torsion Bending. In their own categories, respectively, are CNC Bending machines and Universal Bending Machines-Modular Construction. Classifications are determined by the kind of bends they generate.

Standard Bending tools produce bends without extraordinary geometry. The distance between a bend and material end is rather high, assuming an adequate bearing area. The same is also true from one bend to the next.

U-Bending tools make, as the name implies, ā€œUā€-shaped rods, like piping for below sinks. When the required bends are more tight and narrow than the tool can handle, a U-Bend tool is swapped out for a bending mandrel, which has narrow geometry. Offset bending tools are used to assemble two bends with a small distance between each other in one step. Edgewise Bending tools are used when a bending axis is placed parallel to the tight side of the workpiece.

This type of tool may come equipped with electronic angular measurement component, to ensure a high bending accuracy. Torsion Bending tools are able to rotate the workpiece on a longitudinal axis.

A consumer can alternatively achieve a similar end by using complex assembly groups with standard bends. CNC Bending machines are a fairly recent development, and they have been designed for high flexibility and a quick set-up. They are able to economically bend both single pieces and small batches with the same level of precision and efficiency as series-produced parts. The final category of Rod Bending tool is the Universal Bending Machine-Modular Construction.

This type of tool consists of a basic machine that is adjustable with little effort and can therefore be applied to a number of bends. The exchange of tools, supported by a simple plug-in system, is quick and easy.

The basic machine is comprised of a CNC-operated side stop, a work bench and software for programming and operating. Because of its modular construction, this machine offers an affordable gateway into bending technology.

After the initial investment, a machine can be customized and extended without any conversion. In other words, the basic machine provides a bending stroke, while the kind of bending is determined by the accompanying tool.

Bending tools are great for a number of industries and markets. Types of construction, among other, to which the Universal Bending Machine lends itself, are metal construction, steel construction, metalwork, machine construction and utility vehicle construction.
