Machining technology of seat ring for engineering wheel

Abstract

The invention provides a machining technology of a seat ring for an engineering wheel. The machining technology comprises the steps of section steel rolling, double dimension shearing, edge coiling, aligning and spot welding, flash butt welding, welded joint milling, finishing, knurling, turning, packaging and the like. By means of the machining technology, the material utilization rate and welding quality can be improved, and the production cost can be reduced. In the process of the machining technology, a short stress rolling mill controlled by a microprocessor is adopted for rolling, and the rolling precision is high; high-pressure water is adopted for dephosphorization, and the surface quality is good; a punching machine is adopted for double dimension shearing, and the shearing efficiency is high; during turning, a robot and numerical control machine tool full-automatic assembly is adopted for machining, omni-directional machining of workpieces can be achieved, the equipment assembly is operated by only one person, manpower is saved, electricity consumption and the manual cost are reduced, and the machining efficiency can be improved by 3 times; and a dedicated knurling machine is adopted, and the knurling efficiency is 6-8 times that of a common lathe.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a processing technology for a seat ring for an engineering wheel. Background technique [0002] At present, there are two processing methods for engineering wheel seat rings. The first method is processed by ring forging, which has a low utilization rate of materials, accounting for 24% of raw materials, waste of raw materials, large amount of turning, and low processing efficiency. The second type is made of thick steel plate by hot pressing and then turning. The processing process is followed by flame cutting and cutting, rolling, rounding, CO2 gas shielded welding, welding, grinding welds, hot pressing, turning and other processes. , CO2 gas shielded welding is easy to have welding defects such as pores, and the welding quality cannot be guaranteed; the material utilization rate of thick steel plates only accounts for 40% of raw materials, and the material utilization rat...
