What are the characteristics of cnc pipe grooving machine in terms of structure and process? from as7abecom's blog

cnc pipe grooving machine is a portable field construction hydraulic machine used for pipeline installation, which has the characteristics of small and light, easy to move and disintegrating. * Suitable for cold bending all kinds of seamless steel pipe, this machine in addition to the function of bending pipe, after disassembly can also be used as a hydraulic jack cylinder. At present, with the further release of investment energy, market demand will further return to rational demand. In other words, high-end machine tool products will be more favored by the market. In addition, from the policy level, the state is also more inclined to support high-end machine tool products with independent intellectual property rights and strong market competitiveness. So what are the characteristics of cnc pipe grooving machine in terms of structure and process?

First, the structure

1, cnc pipe grooving machine using touch screen plus CNC module, dialogue operation, simple and easy program setting;

2, the bed structure is stable, not easy to deformation;

3, each gear can set 16 bending Angle, memory can store 16 groups of files;

4, slow positioning function, stable bending Angle, repeatability up to ±0.1°;

5, the error message is displayed on the screen to help the operator immediately eliminate;

6, provide self-developed coordinate conversion bending processing value, software can be installed in the desktop computer editing calculation.

Second, the process

Bend the pipe the same way you bend the sheet metal. In the case of pure bending, when the pipe with outer diameter D and wall thickness t is bent by the action of external moment M, the outer wall of the neutral layer is subjected to tensile stress σ1, and the wall becomes thinner. The inner wall of the neutral layer is subjected to tensile stress σ1, and the wall becomes thicker. Moreover, the shape of the cross section changes from circular to approximately elliptical due to the effect of the resultant force F1 and F2. When the deformation is too large, cracks will occur on the outside wall and wrinkles will appear on the inside wall.

The degree of deformation of the pipe depends on the size of the relative bending radius R/D and the relative thickness t/D, and the smaller the value of R/D and t/D, the greater the degree of deformation. In order to ensure the forming quality of pipe fittings, the degree of deformation must be controlled within the permitted range. The bending of pipe forming * not only depends on the mechanical properties and bending methods of the material, but also considers the use requirements of pipe fittings.
