Welding-free unequal-thickness wheel type engineering machinery wheel and manufacturing technology for same

Abstract

A welding-free unequal-thickness wheel type engineering machinery wheel and a manufacturing technology for the same are provided. A round steel plate with a certain size is molded through a series offorming technologies; welding is not required during all the forming and processing procedures; a wheel type engineering machinery wheel with a traditional way of wheel spokes, wheel rim cylinders andbead seat combined welded together can be replaced; in the welding-free unequal-thickness wheel type engineering machinery wheel and the manufacturing technology for the same, the wheel spokes, the wheel rims and the bead seat are integrated, so great overall surface quality can be achieved; deficiencies of welding difficulties and overall strength deficiencies during the welding and assembling can be overcome; wheel manufacturing technology processes and production management can be greatly simplified; wheel product strength and precision can be greatly improved; and pollution caused by welding can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of mechanism wheels, and specifically relates to a non-welded wheel type construction machinery wheel of unequal thickness, which is used for wheel type engineering vehicles and can replace the traditional three-piece combined welding of spokes, rims, and bead seats. Wheeled engineering machinery wheels, and have higher strength. Background technique [0002] Traditional three-piece welded wheel construction machinery wheels (such as figure 1 As shown) there are many limitations in the production process and the product itself. The spokes and rims of this type of wheel come from two different raw materials, and are made separately through clamping, positioning and other process routes, and finally assembled and welded. Manufacturing and production Divided into three production lines of spoke, rim and assembly, the process is cumbersome, the management is complicated, and the production environment involving...

AI Technical Summary

Problems solved by technology

[0007] The traditional rim cylinder 101 is first welded with the rolled traditional bead seat 102 in the entire circumferential direction, and this welding forms the traditional rim cylinder and the bead seat circumferential weld 105 to form the rim body of the wheel. After the welding seam, it is welded with the traditional wheel spoke 103, and this welding forms the traditional bead seat and the wheel spoke circumference weld seam 107; therefore, there are two welding processes in the assembly welding stage. During the use of the wheel, the traditional wheel rim tube Due to defects in the welded joints 105 between the body and the bead seat and the traditional bead seat and the spokes 107, the welded parts cannot bear a certain degree of cyclic impact stress. Cracks begin to appear at the welding seam 107 of the traditional bead seat and the wheel spoke circumference welding seam, and even completely separate in severe cases
