Description

[0002] Metal pipes are extremely common components in production and life. They can be used as a conveying medium while providing various supporting forces. They can be seen everywhere in life. In order to ensure the conveying capacity of metal pipes, the inside of metal pipes is generally a smooth curved surface structure. In order to ensure the supporting strength of metal pipes while reducing the weight of metal pipes, when metal pipes are stamped, the stamping die on the outer side adopts a die with a spiral groove structure, which can ensure that the outer side of the metal pipe after stamping is a spiral structure. In order to improve the neatness, sealing and connection fit of the end of the spiral metal pipe, it is generally necessary to grind the end of the metal pipe before die stamping.

[0003] When the existing device is used to grind the spiral metal tube, the spiral groove on the side can only be grinded by a worker holding a grinding gun. The grinding efficiency is very low, and it cannot be guaranteed that the spiral groove on the outer side of the metal tube is completely polished and smooth. When the side of the metal tube contains impurities such as rust during stamping, the sealing type of the metal tube end after stamping will be reduced. When stamping the end of the spiral metal tube, the worker is required to align the metal tube end with the stamping device in turn, and then fix it after alignment. The operation before stamping is relatively complicated, the stamping efficiency is very low, and it cannot be guaranteed that the cross section of the metal tube placed by the worker completely overlaps with the stamping die, and the defective rate of stamping is high.
