Periodic Tube Rolling and Its Related Deformation Principle
Periodic tube rolling is a form of rolling process used in the production of metal tubes and rods. This process involves the use of special dies to form metal bars into tubes or rods. The process is known for providing excellent precision and quality control.
In periodic tube rolling, the metal bar is repeatedly passed through rotating cylinders that shape the metal. The driven rolls, or dies, form the material in a figure-eight pattern. As the metal is forced into its shape, the process creates a large number of small wrinkles in the surface of the metal. This causes the metal to form into a tube or rod with evenly spaced ribs and creases on the exterior.
The periodic tube rolling process is ideal for producing metal tubes with a uniform cross section. Because the process is so precise, the tubes can be produced with very tight tolerances. The process also helps to reduce distortions during the tube forming process. As a result, it is possible to create tubes with consistent wall thickness and radius from roll to roll.
The process is also very cost-effective. As the rolls used in periodic tube rolling are relatively cheap and durable, the equipment is relatively inexpensive. Furthermore, the process uses much less energy than other tube forming processes, such as hydraulic extrusion.
Periodic tube rolling is also a very reliable process. As it is a cold-rolling process, the temperature of the tubes is kept between 25 and 30 degrees Celsius. This temperature range helps to ensure that the metal is not over-strained or over-heated during the rolling process. The process also helps to reduce the risk of cracks and fractures in the tubes.
Overall, periodic tube rolling is an advantageous form of tube and rod making, as it is accurate, cost-effective and reliable. The process is used in industries such as automotive, aerospace, and medical to create high-quality metal tubes. The combination of the periodic tube rolling process, with die design and other tube-making methods, has allowed for the production of lighter and stronger tubes than ever before.
