The end cover is composed of a head plate and a steel sleeve, and the steel band in a roll needs to be unwound and straightened before being fed to the shearing machine. The shearing machine cuts the steel band into fixed lengths, and then welds each section of the steel band into a steel sleeve.

Since different specifications of pipe pile end cover correspond to different widths and thicknesses of steel band, and the position of the feeding roller of the traditional equipment is relatively fixed, it is difficult to quickly adapt to the feeding needs of multiple specifications of steel band. The adjustment process is complicated and time-consuming, which affects the production efficiency. Moreover, the positioning accuracy of the steel band during the shearing process is not good, and some equipment lacks effective pressing and guiding structure. The steel band is prone to deviation and wrinkling during feeding and shearing, resulting in large length and width errors of the sheared steel band, which cannot meet the high precision requirements of end cover processing, and thus affects the sealing performance and structural stability of the end cover and the pipe pile.
