Machining process for rotor room of 10 MW and above

Abstract

The invention relates to a machining process for a rotor room of 10 MW and above. The machining process comprises the following steps that a, raw materials are fed; b, rolling is carried out, wherein a large cylinder is rolled through a vertical plate rolling machine, and a cone plate is rolled by adopting a large cone roller plate rolling machine; c, the large cylinder and the cone plate are welded with an inner flange assembly; d, tempering is carried out in a ground sinking type tempering furnace after rounding correction; e, machining and forming are carried out; f, coating on a production line is carried out; and g, packaging after inspection is carried out. Compared with existing machining of a large rotor room of 10 MW or above, the shaping process is reduced, the machining time is greatly shortened, the working efficiency is improved, and the precision of machined workpieces is higher.

Description

technical field [0001] The invention relates to the field of wind power equipment, in particular to a processing technology for a 10MW and above rotor house. Background technique [0002] The large cylinder and the cone plate in the existing rotor room are rolled by ordinary horizontal plate rolling machine, and the large cylinder rolled by the plate rolling machine is easily deformed due to the influence of gravity. Moreover, the upper and lower rolls used for rolling on ordinary horizontal plate rolling machines are straight rolls. For the rotor room above 10MW, the cone plate is thick, large and heavy, and it is easy to roll the cone plate. Slip occurs, it is easy to strain the coiling roller and the steel plate, and the plate is easy to be rolled and thinned, resulting in insufficient precision of the rolled cone plate after it comes off the plate rolling machine, and additional processing and shaping steps are required, and even shaping After all, the usage requirement...

AI Technical Summary

Problems solved by technology

[0002]The large cylinder and cone plate in the existing rotor room are all rolled by ordinary horizontal plate rolling machine, and the large cylinder rolled by the plate rolling machine is easily affected by gravity out of shape

Moreover, the upper and lower rolls used for rolling on ordinary horizontal plate rolling machines are straight rolls. For the rotor room above 10MW, the cone plate is thick, large and heavy, and it is easy to roll the cone plate. Slip occurs, it is easy to strain the coiling roller and the steel plate, and the plate is easy to be rolled and thinned, resulting in insufficient precision of the rolled cone plate after it comes off the plate rolling machine, and additional processing and shaping steps are required, and even shaping After that, the usage requirements cannot be met, and the production efficiency is low.
