Manufacturing method of roller structure

Abstract

The invention discloses a method for manufacturing a drum structure, which belongs to the technical field of mechanical processing. The main shaft of the drum structure is made of 35CrMo material, and the manufacturing method includes: surfacing a layer of transition layer on the main shaft, the transition layer is E501T-1L material; fitting the inner panel to the main shaft, and coaxial with the inner panel Welded on the transition layer of the main shaft; Weld the inner panel into the cylinder so that the main shaft and the cylinder are arranged coaxially; Set the outer panel on the main shaft, and weld the outer panel to the transition layer of the main shaft and the cylinder respectively Together, the barrel, the main shaft, the inner panel and the outer panel are arranged coaxially. In the present invention, a transition layer of E501T-1L material is surfacing on the main shaft. The E501T-1L material has good crack resistance and no cracks will be generated during welding, thereby improving the quality of the main shaft and the inner and outer panels. The welding quality between them ensures the service life of the spindle.

Description

Technical field [0001] The present invention relates to the field of machining techniques, and more particularly to a method of manufacturing a drum structure. Background technique [0002] The turning and closing mechanism of the turntable door opening and closing system includes opening and closing driving devices, a pulley group, a modification pulley, a pretensioning device, and the like. Among them, the opening and closing drive includes a roller structure which is an important part of the load-bearing and transmission of the driving device, which requires a large torque, thereby needs to be made of a material having a large strength of the drum. Structure. [0003] Typically the drum structure includes a cylinder, an inverse plate, an outer flap, and a spindle, wherein the inner web and the outer flaps are welded within the cylinder, and there is a through hole in the middle of the inner unit and the outer flake. After the through hole of the inner panel and the outer plate...

AI Technical Summary

Problems solved by technology

[0005] Due to the high carbon equivalent value of 35CrMo material, the weldability is poor, so the welding quality between the main shaft and the inner and outer webs is poor

Moreover, the main shaft tends to have cracks in the heat-affected zone and cold cracks during welding. Cracks during welding will reduce the service life of the main shaft, thereby affecting the normal operation of the entire drum structure.
