IF Bend, Hebei billion gold piping, IF Bend mounds provided by Hebei billion gold piping. IF Bend, Hebei billion gold piping, IF Bend manufacturers are Hebei billion gold Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) 2013 upgrade been newly launched IF Bend used to connect two same nominal diameter pipe, so Piping for 90 degree turn. IF Bend addition to carbon to the general also contain small amounts of silicon, manganese, sulfur, phosphorus, carbon use can be divided into carbon structural steel, carbon tool steel, structural steel and ease of cutting three types of mounds IF Bend, carbon steel structural steel elements is divided into two buildings structural steel and machine construction methods can be divided by the open-hearth steel smelting, converter steel and electric steel; deoxidation methods can be divided by boiling steel, killed steel, semi-killed steel and special killed steel ; according to carbon content can be divided into low-carbon steel, carbon steel and high carbon steel; press phosphorus, sulfur content can be divided into ordinary carbon steel carbon steel, high-quality carbon steel and high quality steel and super laser forming quality steel elbow: internal, non-uniform thermal stress field of the laser beam shaping is a surface formed by the use of laser technology to achieve new materials forming. The basic principle of the bending process can be summarized as follows: The material is heated in a laser scanning region is formed intermediate a large uniform temperature field bends the price, and the bound material around the cold thermal stress induced by the temperature greatly exceeds the premises with yield limit of the temperature change, resulting in compressive deformation of the plastic intermediate pipe, when the material is cooled to form the final residual stress and bending. The mechanism of laser bending temperature gradient mechanism ∞ Gou, upsetting mechanism (iv) and buckling mechanism. Different mechanisms have different scope and conditions. Laser pipe bending forming mechanism is the use of UM. Compared with other pipe bending, laser bending is a non-contact, no external force is no mold forming technology, processes more flexible. Laser bending forming with high accuracy, short production cycle, flexibility and other characteristics, suitable for small-volume parts production, all kinds of different elements can be formed, high hardness and brittle materials, such as nickel-titanium alloys, ceramics, cast iron and so on. However, this approach equipment investment cost is high, the operator skill requirements are relatively high. As the laser forming of a late start, combined with high processing costs, there is not a lot of coverage of the technology application.
