What is Bending Process? How Bending Measure?

The tube bending process uses a mechanical force to push a metal tube against a customized die, forcing the metal tube to conform to that specific shape with a fixed or variable radius. This kind of process is made possible thanks to extended machinery intended for the bending process of specific tubes made of steel, metal,stainless steel, aluminum, and zirconium copper chrome.

The most relevant element to take into consideration while bending it is the central radius. That needs to be unchanged in comparison with the original diameter of the tube. We also put all our efforts into avoiding the creation of wrinkling and humps, which means a low surface roughness.

The end products result in high-quality items ready to be employed in many different fields: the vehicle industry like bicycle,triangle or wheel barrow bending,baby carriage industry,tube frame area,air conditioner industry,the pharmaceutical industry and the food industry.

When bending pipes or tubes, it is important to make correct measurements. Any mistake at this stage will result in an incorrectly bent pipe or tube, and in many cases, is an irreversible scenario. In other cases, it is time-consuming, and can deform your pipe or tube permanently.Of course correct pipe tube bender choose also is a very important aspect to get accurate,high efficiency and cost effective bending. Automatic CNC pipe bending machineabsolutely is a good choice, but if you only have one bend, same function, Semi automaticNC rotary draw benderis a good choice for saving cost.

1. Estimate the overall length of the pipe. Depending on the length of the bends and the length of the spaces between them, determine the total length of pipe or tubing you require.

2. Measure the distance for the first bend. From one end of the tube, mark the point for the first bend. Here, you need to carefully mark the beginning and the end of the bend. You also need to measure the distance between the bends.

3. Measure the distance for the second bend. Repeat the previous step, but use the vertex of the first bend as the reference/ starting point instead of the end of the tube or pipe. The vertex is the exact point where the two legs of an angle intersect.

Alternatively, you can use the initial reference point (the end of the tube) to measure the distance for all bends.

4. Measure more bends. Repeat the previous step for measuring more bends. Always mark the exact spots as you go along.

5. Measure reverse bends. Repeat step 2, but mark the direction of the bend. It is the same process except that the direction of the bend differs. You also need to deduct the gain.

6. Compensate for spring back when measuring. All tubes and pipes, irrespective of material, experience some amount of spring back. It is dependent on the material, the angle of the bend, and the radius of the bend. This can be compensated for by using two methods:

· With experience and the right methods, you can estimate the amount of spring back and over bend the tube; or

· You can wait for the spring back to occur, measure the angle and then bend the tube accordingly.
