How temperature and curvature turned into the engine of the engine of China pipe bending machine.
Products 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 the surface of the product will appear a lot of fine cracks, in fact, such a problem is not only because of the temperature, but also may be the bend processing material problems caused by high-speed deformation of the product in the process of processing will lead to damage to the processing equipment.
Crack formation conditions, we all know that the product in the process of processing the length of its crack can reach the longitudinal axis perpendicular to the grain boundary, also said perpendicular to the tensile pipe clamp, after heat treatment, the product needs to be bent, the product surface microcrack will become a crystal tug, the general study of the mechanics of pipe bending processing equipment and microcracking, the tensile strength of the product at room temperature is not affected.
Pipeline transport processing of its bend processing is different radius and angle of the different products bending direction will also change, such products have become an integral part of the engineering pipeline, if the product wall thickness changes and bending mechanical properties change to will affect the quality of the product, the product in the processing of its technology is very important.
In fact, the processing technology of the CNC Pipe bender is very important, in the process of processing we must ensure that the product processing temperature and the degree of bending, because most of the cracks on the surface of the product are due to the temperature of the processing process, the higher the temperature of the micro-crack will gradually increase, a small part of the product surface because of the micro-cracking caused by hot bending.
