1. Laser cutting tube type regularization
    To prevent excessive arcs, sinuous curves, compound bends, and greater than 180 when planning and piping. The arc. Excessive arcs not only make the tooling bulky, but also limited by the size of the pipe cutter machine; the ambiguous curve and the compound bending plan are unfair, which greatly hinders the machined and active production, making it difficult for the operator to break away from the bulky physical strength. Labor; greater than 180. The arc prevents the pipe cutter from being unloaded.

    2. Bending radius scaling
    The bending radius should be such that even "one tube one mold" and "multiple tube one mold" are realized. For a pipe, no matter how many bends, the bending angle can only have one bend radius. Since the laser pipe cutter does not change the module during the bending process, this is "one tube and one mold". The "multi-tube and one-module" is that the tube of the non-stop diameter specification should only use a uniform set of modules to bend the shape of the tube, even if it accepts a curved radius, so that it is beneficial to eliminate the number of modules.
    3. Proper bending radius value
    The thickness of the bend radius of the catheter determines the size of the resistance experienced by the catheter during bending. Generally speaking, the large diameter of the pipe diameter is small, and the internal wrinkles and the slipping signs are likely to occur when bending, and the bending quality is difficult to be wrapped, so that the R value of the pipe cutting die is usually selected to be 23 times the diameter of the pipe.

    4. Moderate bending rate
    The important influence of the bending rate of laser cutting machine on the forming quality is as follows: the speed is too fast, it is easy to cause the flatness of the pipe bending department, the roundness is not up to the requirement, and the pipe is pulled and broken; the rate is too slow, and the pipe is easy to be caused. The wrinkles and the compacted block slip, and the large diameter pipe is liable to form a depression in the curved portion of the conduit. For a large number of tests on these two laser pipe cutters, it is advisable to determine the bending rate of the pipe to be 20% - 40% of the maximum bending rate of the machine.
    5. Compliant mandrel and its position
    The mandrel plays an important role in the bending process to support the deformation of the inner wall of the conduit bending radius. Now the domestic pipe is bent on the machine tool. If the mandrel is used, the quality is difficult to guarantee. There are many kinds of mandrel situations, such as column mandrel, universal single, double, triple, and four ball head mandrel, oriented single, multi-ball head and so on. In addition, the position of the mandrel also has a positive effect on the bending of the catheter: in theory, its tangent should be flush with the tangent of the bending die, but a large number of tests prove that 1~2mm is better in advance, at this time The quality of the tube is more ambition. Of course, the amount of advance is too large, which will cause the appearance of the so-called "goose head" on the outer wall of the bending department.
