The laser pipe cutting machine clearly specifies the RX value and the external thinning amount at different pressure levels to control the RX and SX values, thereby ensuring quality. The position of the neutral axis of the automatic pipe cutting machine is different from the position of the bending method when the external pressure is pulled. When compression bending work, the neutral wheelbase is about 1/3 from the outer wall, and when bending work, the neutral wheelbase is about 2/3 from the outer wall.
Therefore, the use of rotary bending method is also conducive to the bending of thin-walled tubes. The bending accuracy of tire is also one of the factors affecting the bending quality. In the manufacturing process of curved tires, in addition to controlling the specifications and size requirements within a certain tolerance range, the user also needs to select the corresponding curved tire according to the diameter of the bend pipe during use.
The bendability of the pipe itself and surface corrosion may also affect the quality of the elbow. In the field construction process, it is necessary to understand the material and processing properties of the processed pipeline, and to make production judgments on surface corrosion.
According to the pipe processing acceptance specifications, CNC pipe cutting machine: cold-formed steel pipe, medium and low pressure 4D, high pressure 5D. Therefore, our curved tire design is r=4d, so the production of the pipe cutting machine is mainly based on the selection of the relative wall thickness SX.
