Auto-matic paper tube bend machine, as the name suggests, is a machine for bending tubes. The Auto-matic paper tube bend machine is mainly used in papermaking and has the advantages of multiple functions, reasonable structure, and simple operation. Auto-matic paper tube bend machine The paper tube is automatically rolled into the machine horizontally, which is stable and reliable. The elbow feeding mechanism adopts a mechanical cam mechanism, which ensures the flexible feeding of the mold under high-speed production. So that the quality of the elbow does not change due to the increase in speed. The five-position dial is automatically controlled by the computer system for precise indexing and positioning. Continuously dial the paper tube into the working position to bend, withdraw, and pull out. Auto-matic paper tube bend machine can be set through the touch screen to realize three functions of inner bend and outer bend machine. The whole machine has frequency conversion speed regulation. The paper tube crimping machine is quick and easy to replace the mold, no manual alignment is required, the mold is installed quickly and modularly, the computer automatically recognizes the position, and the error is less than 0.05MM.

The production capacity of the Auto-matic paper tube bend machine determines its field of application. Models that can bend diameters below 10mm are generally used for oil pipelines (thin materials and many alloy materials); models with a bending capacity of 10-38mm in diameter are the most useful, and are used for common chairs and other pipes Bending; the diameter of the elbow is 38-50mm is a type of model; the model with a bending capacity of 50-76mm is not as widely used as the diameter of 38mm; the model with a diameter of 76-130mm is generally used in automobile exhaust pipes, etc. Field; if the diameter of the elbow is more than 130mm, a profile bending machine is required, such as oil pipelines.

At present, Auto-matic paper tube bend machine models with a general bending capacity of less than 130 mm in diameter can do three-dimensional. CNC 3D pipe bender that can bend most shapes. The size of R depends on the mold, but a small R is difficult to bend, and the machine can configure bending molds with corresponding specifications. But there are exceptions. The British have a very flexible pipe bending machine, which does not rely on molds, has any shape, is very expensive, and is purchased by major yacht manufacturers. The better three-dimensional pipe bender has 3 layers of molds, which are automatically selected according to the size of the bending R. In addition, the bending and thrust of the pipe bender can meet its maximum limit requirements.

Large diameter Auto-matic paper tube bend machine cannot do 3D. It can do multi-R bending or coil-type bending, which is mostly used for pipelines. Generally, there are three rollers, the upper roller is a rotating roller, the two side rollers move up and down, and the better ones are equipped with brackets that can move up and down, left and right. The type bending machine has a fatal disadvantage: it produces straight-line segments. If you bend the circle, you must cut off the preceding straight segment.
