Features and applications of biaxial and single-axis pipe bending machines

Pipe bending machines from several dimensions; Such as automation, gutters, driving force, head rotation and number of movements can be checked. For many potential buyers today, the term "CNC" refers to the machine's ability to move axially. In other words, they think that a CNC machine must have three or five axes or more. But this is not the case. A two-axis pipe bending machine can be CNC and a three-axis machine can not be CNC.

Features and applications of biaxial and single-axis pipe bending machines

CNC pipe bending machines

Pipe bending machine is used to bend all types of pipes, including steel, stainless steel, aluminum and copper pipes. These machines are able to bend a straight pipe based on the amount of degree and axis. Machines that can bend pipes on only one axis (x-axis) are called single-axis pipe bending machines. A bending machine can use a variety of driving forces, so the driving force of a pipe bending machine can be hydraulic or electrical. They are rarely equipped with mandrel systems and automatic feeding (tube feeder). But they can also be equipped with saw cutting systems. Not only are these types of machines not capable of bending complex pipes, but they are also inferior in accuracy to other multiaxial pipe bending machines. They are mostly used in industries such as chair making, table and furniture making, wheelchair frames and bicycle frames. Although these types of machines are able to bend the pipe in only one axis, but can be made automatically and semi-automatically with NC control.

The question now is, is it possible to produce two-dimensional bends with single-axis machines? The answer to this question is not automatically but manually yes. Some pipe bending machine operators release the machine collet after single-axis bending and turn the pipe to one side. Rotating the pipe at any size can create a two-dimensional bend. it should be noted that the rotation of the tube by the operator can not create an exact angle to the X-axis and may cause several degrees of deviation. Not only turning the pipe by the operator reduce the accuracy of the angle, but opening and closing the colt and turning the pipe is a waste of time and production capacity will be significantly reduced. In this type of single-axis bending machine, the only part that can be controlled is the degree of bending in the X-axis and sometimes at the cutting time (if the machine is equipped with a cutting system).

The important question now is, can single stack machines be CNC? The answer is yes, because the cutting time, cutting order, pulling back and forth tube (on the same axis) and mandrel movement can be done with PLC or mini PLC command. This type of machine is called a CNC Single stack tube bending machine.

The driving force of single-axis pipe bending machines

The driving force of these machines to bend and push the pipe towards the head of the machine can be hydraulic, electric, hybrid of electric hydraulic type or hybrid of electric pneumatic type. Pipe bending machines, which are all electrically operated, are structurally simpler and cheaper than other bending machines, and their biggest advantage is not only their low price, but also their easy replacement of pulley and related tools. Today, for professional manufacturers in the field of pipe bending, combined machines (hydraulic, pneumatic and electric) are the most popular. Not only those machines have enough power to bend, but their speed and accuracy in performing the bending process is their most important advantage.

Some of the advantages of single-axis bending machines:

The cheapness of these types of machines compared to other machines that have multiple axes, if we assume the options of machines (saw, tube feeder and mandrel) are the same in both types:

  1. Ability to produce serial and single production
  2. Cheap maintenance
  3. Convenience and simplicity in exchanging money and tools
  4. To see the videos of uniaxial bending machines, you can refer to the selected videos of pipe bending machines of Factoronid site or the following sites:

Biaxial CNC pipe bending machines

As its name suggests, this type of pipe bending machine is able to bend straight pipes in the X and Y axes. These machines can also be equipped with options such as mandrels, saws and tube feeders. Due to the ability to move on two axes, the speed and accuracy of this type of machine is much higher than single-axis pipe bending machines. These types of pipe bending machines, which can be equipped with PLC or mini-PLL system, bend pipes with a tolerance of 0.1 mm in terms of degree and size. The driving force of many of these machines is the hydraulic force in the head part and the electric force in the rotating part. However, some manufacturers of CNC pipe bending machines have designed machines that use only electric force to bend thin pipes.

An important advantage of this type of machine is the use of oil and hydraulic equipment and in terms of noise pollution, they create the least noise pollution.

Biaxial CNC pipe bending machines can be made automatically or semi-automatically. Fully automatic machines are equipped with a cutting system, mandrel system, tube feeder, upload system, seam detection system and sometimes online measurement system, and semi-automatic machines may be equipped only with mandrel system and cutting system. It is very clear that fully automatic two-axis CNC pipe bending machines have a much higher speed than other two-axis bending machines.
