Subsequently, the Z-shaped filter plate 66 can intercept the dust, and the filtered air will be discharged; Then, the second motor 31 and the second electric telescopic rod 34 are started again, so that the qualified old steel pipes to be bent with the outer wall cleaned can be driven to rotate downward and contact the bending guide roller 29. Subsequently, the first electric telescopic rod 24 will start, so that the bending rotating rod 26 can be driven to move towards the side close to the qualified old steel pipes to be bent by moving the slider 25, and then the bending rotating pipe 28 can be driven to move towards the side close to the qualified old steel pipes to be bent. When the bending rotating pipe 28 contacts the outer wall of the qualified old steel pipes to be bent, the first electric telescopic rod 24 is turned off. After that, the first motor 21 will start, so that the bending rotating plate 23 can be driven to rotate, and then the bending rotating pipe 28 can be driven to rotate and bend the qualified old steel pipes to be bent after cleaning. After the bending process, the bending rotating pipe 28 and the like are reset and the bent old steel pipes are removed. Subsequently, the subsequent cleaning operation and bending operation of the outer wall of the qualified old steel pipes to be bent are carried out in sequence according to the above steps. After the device is used, the Z-shaped filter plate 66 is removed and cleaned, and the dust in the dust removal box body 61 is cleaned. In addition, the solid particle impurities remaining in the second outer frame 511 need to be cleaned.
