[0025] image 3 It is a schematic diagram based on the interference behavior of the three-dimensional free bending deformation of the pipe, Figure 4 It is a schematic diagram of the pipe that interferes with the base of the machine head during three-dimensional free bending deformation. In the three-dimensional free bending deformation, it is necessary to form the geometric shape shown in the pipe 14. If it is defined that the starting direction of the pipe 14 is downward and the bending radius is 125mm, the formed pipe will interfere with the base 9 of the machine head. Affect the subsequent forming process.
[0026] In this example, the specific steps to prevent interference are as follows: First, for the pipe 14, first determine the shape that needs to be bent, including the bending radius, the bending angle, the bending arc length, the bending direction, and the overall size of the formed pipe; According to the bending direction and the bending radius, determine whether the ...

[0028] Figure 5 It is a schematic diagram of the pipe that interferes with the ground during the three-dimensional free bending deformation. In three-dimensional free bending deformation Figure 5 The curved pipe shown has a bending radius of 1200 mm and includes a straight section 16 and a curved section 17. When the initial direction of bending is downward, the formed pipe will interfere with the ground, which will affect the subsequent forming process.
[0029] In this example, the specific steps to prevent interference are: Figure 5 For the curved pipe shown, first determine the shape that needs to be bent, including the bending radius, the bending angle, the bending arc length, the bending direction, and the overall size of the formed pipe; the second is to determine whether the formed pipe is based on the bending direction and the bending radius It will interfere with other parts of the three-dimensional free bending system. When the initial direction of the bending is do...

[0031] Image 6 It is a schematic diagram of the pipe that interferes with the servo motor in the three-dimensional free bending deformation. In the three-dimensional free bending deformation, it is necessary to form the pipe such as Image 6 For the geometric shape shown, if the starting direction of the tube bending is defined as downward and the bending radius is 250mm, the formed tube will interfere with the servo motor and affect the subsequent forming process.
[0032] In this example, the specific steps to prevent interference are: First, for the pipe, first determine the shape that needs to be bent, including the bending radius, bending angle, bending arc length, bending direction, and the overall size of the formed pipe; The bending direction and bending radius determine whether the formed tube will interfere with other parts of the three-dimensional free bending system. When the initial direction of bending is downward and the bending radius is 250mm, the formed tube w...
