The process is as follows: After the straight pipe is cut, the induction coil is put on the part of the steel pipe to be bent by the bending machine, the pipe head is clamped by the mechanical arm, and the intermediate frequency current is passed through the induction coil to heat the steel pipe. When the temperature of the steel pipe When is raised to the plastic state, the rear end of the steel pipe is propelled by mechanical thrust for bending, and the part of the bent steel pipe is quickly cooled with a coolant, so that heating, advancing, bending, and cooling, the bent pipe is continuously bent. Bend it out.
Hot-simmered steel bending pipes are mainly used in arc-shaped steel structures, tunnel supports, motor vehicle curved beams, subway projects, aluminum doors and windows, ceilings, cylindrical inner skeletons, balcony handrails, shower room doors, production line tracks, fitness equipment, etc. kind of industry.
Cold-simmered steel bending pipe is a method of bending processing at room temperature without heating or changing the material structure, which is called cold-simmered steel bending pipe. To prevent the pipe from collapsing or deforming during the bending process, some auxiliary materials or equipment, such as springs, are often filled in the pipe. Cold bending is generally used for small-diameter pipes, while large-diameter pipes cannot be cold-bent!
The material of the bending pipe is cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, etc. The cold-simmered pipe is bent with a complete set of bending dies and is mainly used for oil, gas, liquid infusion, etc.
