The importance and development of hydraulic numerical control bending machine mould

Many sheet metal enterprises need to measure the built-in angle of sheet metal, that is, when the device is bent, they can continue to measure its angle. At this time, a hydraulic CNC bending machine mold is needed for operation. With the help of the hydraulic numerical control bending machine, the thickness, rolling deviation, tensile strength and other characteristic parameters of the plate will be more accurate, so as to improve the quality of the plate. At present, many bending machine molds are now used and processed, so that the accuracy of the produced molds will be higher.

At the same time, many hydraulic CNC bending machine dies are carefully created through many processes, its accuracy can be said to be quite high, so that the steps of error correction can be omitted, and the processing cost can be reduced. In addition, the numerical control bending machine die with heat treatment is more reliable than the common bending machine die, because its precision is more durable and standardized.

From the perspective of the demand situation of the whole hydraulic CNC bending machine mold market, its market potential is still very huge. On the contrary, the growth trend of some countries in the world, especially in Europe (Eastern Europe) and North America, is extremely stable, especially in Eastern Europe. But in some small aspects, the sheet metal bending machine mold began to show some slow trends. Why?

According to the research data of bending machine die experts, the main reason why the growth demand of the die is slowing down is that the service life of the bending machine die is constantly increasing. Users do not need to consider whether to replace the new bending machine die in a long period of time. In addition, the manufacturer puts forward some significance for the manufacturing process of the whole blade. The previous tools are all Mold with single function.

At present, the development of mold is going to be more large-scale, as small as a few tons to dozens of tons. At this time, it is necessary to bear the heavy weight of the working table of the hydraulic CNC bending machine tool. That is to say, the machine tool must have the characteristics of large load-bearing and high rigidity, and the table size and working stroke correspond to it from a distance. In addition, in order to ensure the machining accuracy and surface quality of parts, the dynamic and static stiffness, positioning accuracy, tracking accuracy and anti vibration ability of high-speed machine tools must be greatly improved. High speed and high power machining is always the most important direction of machine tool development. High speed milling has shown great advantages in the mold processing of hydraulic numerical control bending machine. In order to adapt to the machining of the die cavity surface, the radius of the cutter should be smaller than the minimum circumference radius of the die cavity surface, so as to avoid "interference" between the cutter and the workpiece during the machining process. Multi axis linkage and good comprehensive cutting ability of deep hole cavity mold cavity is composed of complex space six curved surface and groove, and many molds have deep hole cavity, five axis linkage machining center can be used, in addition to the linear motion of three coordinates, there are two rotary coordinates of the feed motion.
