Abstract

The embodiment of the invention discloses a winding drum welding method and belongs to the technical field of winding drum manufacturing. The winding drum welding method comprises the steps of providing a drum shell and two spoke assemblies; assembling and positioning the two spoke assemblies to the two ends of the drum shell correspondingly; fixedly connecting the middle portions of the two spokeassemblies through a positioning rod which is located in the drum shell; using a positioning plate to conduct positioning between the spoke assemblies and the drum shell; preheating the drum shell and the spoke assemblies to enable the preheating temperature of the drum shell to be higher than the preheating temperature of spokes; and welding the spoke assemblies at the two ends of the drum shellto the drum shell correspondingly to obtain a winding drum. By means of the method provided by the embodiment of the invention, welding deformation and welding cold cracks, especially lamellar tearing of the drum shell, of the winding drum can be efficient prevented.

Description

technical field [0001] The invention relates to the technical field of roll manufacturing, in particular to a roll welding method and the roll. Background technique [0002] In recent years, the specifications of the reels in hoisting machinery have been continuously increased, and various large reels have been widely used. [0003] The reel usually includes a cylinder shell and spoke assemblies welded at both ends of the cylinder shell, and each spoke assembly includes a hub and spokes welded on the hub. When making the reel, the spokes and hubs on both sides are first welded into a spoke assembly, and then the spoke assembly is welded to both ends of the shell, that is, the outer circumference of the spokes on both sides is welded to the inner wall of the shell. [0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: at present, T-shaped welding is used between the spoke assembly and t...
