The tube bending process can create anything from household and automotive piping to tubing for aerospace applications. Even office supplies, like paper clips, is formed using tube bending dies, which bend the object into its shape. Some of the machines that perform tube bending operations can be used by hand; many, however, use complex tube bending calculations that are input into a CNC tube bending machine.
Machines that are CNC, which stands for computer numerical control, can be programmed to bend tubes to any specification, and they can perform tube bending calculations automatically. This ensures that their operators aren’t doing unnecessary work, so they can finish high volume jobs quickly and accurately. Another feature of tube bending machines is that they rely on automation, so the tubes are bent at the right angle each time. Many of these machines can save and preset work settings to ensure a fast turn around time.
The tube bending formula for a project depends on the tube’s material, weight, length, area, and other specifications. There are many charts available online that can help convert standard to metric if needed; many CNC tooling programs should also be able to convert the right calculations and measurements. Why do tube bending calculations need to be exact? Sometimes it’s necessary in order for the part being manufactured to work. Using the right calculations also ensure that fewer parts are wasted in the tube forming process.
The ways in which tubes and pipes are bent depend on their materials and size. Some use extreme heat and things like hot sand in order to shape these pipes. Many of these processes will use a mandrel, which is a steel rod-like object inserted into the pipe to prevent it from collapsing or breaking while being bent.
Those looking to purchase new tube bending equipment for their factories or shops should weigh the pros and cons of different tube bending machinery and their calculating abilities. For those with serious inquiries, contacting a tube bending machine manufacturer is the best option. Those with general questions can leave a comment below.
