Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spiral duct U-shaped hoop processing, in particular to an automatic processing equipment for spiral duct U-shaped hoop. BACKGROUND

[0002] The spiral duct U-shaped hoop is a kind of accessory for connecting and fixing the spiral duct, which is usually made of galvanized steel sheet, and has a U-shaped structure that can fit the outer arc of the spiral duct. Through the connecting pieces such as bolts, the two ends of the U-shaped hoop are connected with the two sections of the duct or the duct and other components, so as to achieve the functions of fixing and sealing, and ensure the stable operation of the duct system. The U-shaped hoop is widely used in duct engineering such as ventilation and air conditioning.

[0003] In the bending forming process of the U-shaped hoop, the manual bending method is generally used. Since the manual operation force is difficult to accurately control, and there is no unified positioning reference, the angle deviation of the bent U-shaped hoop can reach ±3°, and the arc error can reach 2mm at most. This not only reduces the fitting accuracy of the U-shaped hoop and the spiral duct, increases the installation difficulty, but also causes the rework rate of unqualified products to be as high as 15%, which seriously affects the overall production progress.
