Embodiment Construction

[0009] A kind of sealing method of metal pipe class described in this embodiment, the steps are as follows:

[0010] In the first step, the sealing end of the metal tube to be sealed is punched into a trumpet shape; in the second step, the edge of the circular metal block is turned up and the horn-shaped part of the metal tube is hemmed by the edge wrapping machine processed so that the metal block seals the ends of the metal tubes.

Abstract

The present invention relates to a sealing method, especially a sealing method for metal pipes; the purpose of the invention is to provide a sealing method for metal pipes that reduces labor intensity, improves production efficiency and ensures the quality requirements of joints; the first The first step is to punch the sealing end of the metal tube that needs to be sealed into a trumpet shape; the second step is to turn up the edge of the circular metal block through the wrapping machine and wrap the horn-shaped part of the metal tube. Therefore, the metal block seals the end of the metal pipe; the sealing method of a metal pipe designed in the present invention changes the original spot welding method, and seals the metal pipe through the edge wrapping method, so that it is no longer The connecting parts need to be polished and refined, which reduces labor intensity, improves work efficiency, and ensures the production quality requirements of the product.

Description

technical field [0001] The invention relates to a sealing method, in particular to a sealing method for metal pipes. Background technique [0002] At present, the sealing method of metal pipes in enterprises is generally to connect the end of the metal pipe to be sealed and the metal block matched with it into one by spot welding. However, this sealing method has the following disadvantages: first, the connection is troublesome and takes a long time; There are protrusions, which require manual grinding and finishing of the raised parts, which not only reduces work efficiency, increases labor intensity, but also leads to unqualified product quality or needs to be reworked. [0003] In view of the above problems, we urgently need to solve them. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a sealing method for metal pipes that reduces labor intensity, improves production efficiency and e...
