A method of manufacturing a drum structure

Abstract

The invention discloses a manufacturing method of a roller structural member, and belongs to the technical field of welding. The roller structural member comprises a barrel, an annular plate, an inner side plate, an outer side plate and a rotating shaft, the inner side plate is provided with a first installation hole, and the outer side plate is provided with a second installation hole. The welding method includes the steps that the rotating shaft and the inner wall of the first installation hole are welded to form a rotating shaft assembly, and the rotating shaft is perpendicular to the inner side plate; the annular plate is welded into the first end of the barrel and is perpendicular to the axis of the barrel; the inner side plate is welded to the barrel; the outer side plate is installed on the end face of the second end of the barrel, the rotating shaft is inserted into the second installation hole, and the outer side plate is welded to the barrel and the rotating shaft. According to the manufacturing method, a two-face welding manner is adopted for the welding barrel and the annular plate, part of welding work needs to be completed in the barrel, the rest of welding lines are welded outside the barrel, the construction environment and the working condition of operators are greatly improved, and the quality of welding lines is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a method for manufacturing a drum structure. Background technique [0002] The opening and closing mechanism of the reversing door opening and closing system includes an opening and closing drive device, a pulley block, a reversing pulley, a pre-tensioning device, etc. Among them, the opening and closing drive device includes a drum structure, which is an important part of the load-bearing and transmission of the opening and closing drive device. The drum structure needs to bear a large torque, so when welding the drum structure, the welding The requirements for welds are relatively high. [0003] Usually, the drum structure includes a cylinder, an annular plate, an inner plate, an outer plate and a rotating shaft, wherein the annular plate is welded in the cylinder and is close to the first end surface of the cylinder; the inner plate is welded in the cylinder and is close to ...
