With the development of my country's pipe bending machine industry and the continuous update of technology, it has brought a lot of convenience to our daily lives. At present, various types of automatic pipe bending machines continue to fill the gap in the market to meet different needs. At present, the main types of pipe bending machines on the market mainly include CNC automatic pipe bending, semi-automatic pipe bending and manual pipe bending. There are still some minor problems in the processing of the product, which means that there are still many technical problems to be solved in the bending process.
During the processing of the product, when the temperature exceeds a certain value, the surface of the product will deform to a certain extent, which will cause a large number of micro-cracks on the surface of the product. In fact, this problem is not only caused by temperature, it may also be caused by the problem of the bending pipe processing material. High-speed deformation of the product during processing will damage the processing equipment.
Under the conditions of crack formation, we all know that the crack length can reach the longitudinal axis perpendicular to the grain boundary during the product processing, that is, perpendicular to the tensile pipe clamp. The product after heat treatment needs to be bent. The crack will become a pull crystal. In general, the mechanics of the pipe bending processing equipment and the microcrack situation were studied. The tensile strength of the product will not be affected by the internal temperature.
When the pipeline is transported and processed, the bending direction of different products with different radii and angles will also change. These products have become an indispensable part of the engineering pipeline. If the wall thickness and curvature of the product change, the change in the mechanical properties of the product will affect the quality of the product. When processing the product, technology is very important.
In fact, bending tube forming technology is very important. The processing temperature and product curvature must be determined during the processing, because most of the cracks on the product surface are affected by the processing temperature. As the temperature increases, the number of micro-cracks that appear will gradually increase, and a small part of it is caused by the micro-cracks on the product surface due to thermal bending.
