What is the purpose of mandrel in tube bending?

In the case of individual bending, the tube with outer diameter D and wall thickness S is bending under the force of outer frame. The outer wall tube is thinned by the work of pulling, but the inner tube wall is thickened by the work of pressure σ.(See Figure 1a). The cross section of tube bend is change into a shape of oval through the resultant force F1 and F2. (See Figure 1b). The inner wall tube may be wrinkled due to loss of stability (See Figure1c). To avoid these situations, we should take some corresponding measures. For example, mandrel bender is one of the most commonly used and effective methods.

Figure 1: the force and change when tube bending. (a) 

       The force when the tube disorderly change. (b)

       The cross section change when tube bending.(c)The inner tube wall wrinkle when tube bending.

Sometimes  the relative bending radius R/D is small or relative wall thickness S/D is small during production. Under such conditions, in order to produce high-quality tube ,we will insect a suitable mandrel to avoid flattening and wrinkling at arc when bending. This process is called mandrel bend.(See Figure2)

Examples of mandrel tube bender 100NC-DW applications

The bendable maximum diameter of mandrel tube bender 100NC-DW is 100mm and thickness is 7mm . This mandrel tube bender is used to produce tricycle frame  in China and Peru.The tricycle frame use rectangular steel tube with 40mmx80mm, within the capacity of the mandrel tube bender for sale.

Tricycle frame

As shown in the figure above, a mandrel rectangular tube bender need to be bend each 3 times , the operator need to input the angle of bend 3 times in screen, and put the material into mandrel tubing tube bender,step on  the foot switch. The mandrel tubing tube bender will finish work automatically. After each work, the operator needs to take out the material, and put it in the proper position for the second bending. The hydraulic mandrel tube bender 100NC-DW use hydraulic system provides power,  it has highly accuracy, and the operate process is very easy. When input the work dates, the operators just need to pay attention to putting the correct angle in turns and corresponding position.

In addition to producing tricycle frame, the mandrel tube bender 100NC-DW also can produce other product such as truck exhaust pipe, fitness equipment and boiler tube etc.
