Technical Field

[0001] The utility model relates to the technical field of metal air ducts, in particular to a device for compacting closed seams between layers of rectangular metal air ducts. Background Art

[0002] Air ducts are piping systems used for air transportation and distribution. There are two types: composite ducts and inorganic ducts. According to the cross-sectional shape, air ducts can be divided into circular ducts, rectangular ducts, oblate ducts, etc. Among them, circular ducts have the smallest resistance but the largest height and are complex to make, so rectangular ducts are mainly used. According to the material, air ducts can be divided into metal ducts, composite ducts, and polymer ducts.

[0003] However, in the existing technology, when compacting the seam edges of rectangular metal air ducts, it is necessary to manually knock the closed seam of the air duct repeatedly to shape the seam edges, which is labor-intensive and has low work efficiency. In addition, the air duct lacks a fixing device and is easy to move when the air duct is subjected to force, affecting the compaction effect of the closed seam. In order to solve the above problems, we propose a closed seam interlayer compaction device for rectangular metal air ducts. Utility Model Content
