- Now the main pipe bender varieties in the market are CNC automatic pipe bender, semi-automatic pipe bender and manual pipe bender.
With the development of China's pipe bender industry and the continuous updating of technology, it has brought us a lot of convenience in our daily life. A variety of automatic pipe bender varieties continue to fill the market vacancy and meet various needs. Now the main pipe bender varieties in the market are CNC automatic pipe bender, semi-automatic pipe bender and manual pipe bender. In terms of product processing, there will still be some small problems, which indicates that there are still many technical problems to be solved in elbow processing, such as how to control the temperature and bending degree during elbow processing?
In the process of processing, when the temperature exceeds a certain value, the surface of the product will appear a certain degree of deformation, so that there will be a lot of fine cracks on the surface of the product. In fact, this problem is not only caused by the temperature, but also caused by the bending material, In the process of processing, high-speed deformation of products will lead to damage of processing equipment.
We all know that the crack length of the product in the process of processing can reach that the longitudinal axis is perpendicular to the grain boundary, that is, perpendicular to the tensile clamp. After heat treatment, the product needs to be bent, and the microcracks on the surface of the product will become crystal dragging. Generally, the mechanics and microcracks of bending equipment are studied, The tensile strength of the product will not be affected by the indoor temperature.
When the pipeline is transported, the bending process is different in radius and angle. The bending direction of the product will also change. Such a product has become an indispensable part of the engineering pipeline. If the wall thickness of the product changes and the bending mechanical properties change, the quality of the product will be affected, When the product is processed, its technology is very important.
In fact, the pipe bending machining technology is very important. In the process of processing, we must ensure the processing temperature and bending degree of the product, because most of the cracks on the surface of the product are affected by the temperature during the processing. The higher the temperature is, the more microcracks will appear, and a small part is due to the microcracks on the surface of the product during hot bending.
