Description

Technical Field

[0001] The present invention relates to the technical field of air duct manufacturing equipment, and particularly to a galvanized steel sheet connecting device. Background Art

[0002] When manufacturing air duct plates, usually a combined corner seam is made at the transverse ends of the galvanized steel sheet, and then two adjacent galvanized steel sheets are connected by the combined corner seam. After that, the combined corner seam part is hermetically connected. The length of the air duct can usually reach several meters or even dozens of meters, and there are several combined corner seam parts on each air duct plate. At present, the method for hermetically connecting the combined corner seam part is as follows: manually using a hammer or other percussion tools to densely hammer the combined corner seam part, which is time-consuming and laborious, and the hammering force is uneven, making it difficult to ensure the hammering effect. More seriously, the noise during the hammering process is extremely loud. Workers working in such a noisy environment for a long time will suffer from dizziness, tinnitus, and even damage to the eardrum.
