The bending machine is used to bend pipes and sheets in the same way. Cold bending pipe is a type of pipe that is cut from a straight pipe and then pushed by a pipe bending machine. A sensing ring is placed on the part of the pipe that needs to be bent, and a mechanical arm is used to clamp the pipe head. A medium frequency current is passed through the sensing ring to heat the steel pipe. When the temperature of the steel pipe rises to a plastic state, mechanical thrust is used to push it at the back end of the pipe for bending. The bent steel pipe is quickly cooled with coolant. In the case of pure bending, when a pipe with an outer diameter (outer edge diameter) of D and a wall thickness of t bends under the action of external torque M, the outer wall of the neutral layer is subjected to tensile stress σ 1, causing the pipe wall to become thinner.
The inner wall of the neutral layer is subjected to tensile stress σ 1, causing the wall to thicken. Moreover, the cross-sectional shape changes from circular to approximately elliptical due to the combined forces F1 and F2. When the deformation is too large, cracks will appear on the outer pipe wall and wrinkles will appear on the inner pipe wall.

Stainless steel bending pipe processing

The processing and manufacturing process of stainless steel bent pipes should be strictly carried out in accordance with the requirements. A U-bend pipe is called a bend pipe, which is also a type of pipe fitting. U-bends are divided into cold bending and hot bending. Generally, small and medium-sized pipe diameter elbows can be obtained through cold bending processing; Large diameter pipes require hot bending. Mainly used for bending pipes made of non-ferrous or black metals, it can be applied to departments such as building materials, shipbuilding, chemical industry, metallurgy, boilers, and heavy machinery manufacturing.

Before processing stainless steel bent pipes, the anti-corrosion pipes used for cold bending should be straightened, and the curvature after adjustment should not exceed 1 ‰ of the pipe length. Spiral coils are generally coiled or mosquito coils with a diameter of 0.5cm to 20mm and a thickness of 0.1cm to 2.0mm; Widely used in industrial fields such as chemical, mechanical, electronic, power, textile, rubber, food, medical equipment, aviation, aerospace, communication, petroleum, etc.
During the processing of stainless steel bent pipes, the position of the core shaft should be accurate, with an error not exceeding 5mm, to ensure that the core shaft is fully supported.
During the CNC bending process, if it is found that the bent pipe deviates from the preset position, it should be adjusted in a timely manner to maintain the flat bending of the bent pipe.
The welding seam of the steel pipe produced by CNC bending should be between 9 o'clock and 10 o'clock or 3 o'clock and 2 o'clock, and the inner bend should be close to the neutral line position and at least 50mm higher than the pipe bending machine's support mold.
After the processing and production of stainless steel bent pipes, the core shaft should be restored and adjusted to its original state to avoid deformation under stress.
The processing and production process of 7 stainless steel bent pipes should be carried out continuously, with a footage of 300mm each time. To ensure uniform curvature of the bent pipes.
