specific Embodiment approach

[0063] The present invention relates to a specific embodiment of a manufacturing process of a wind turbine casing, comprising the following steps:

[0064] 1. Processing of the casing:

[0065] A. Cutting material:

[0066] a. Prepare a steel plate with a thickness of 55mm, a width of 1850mm, and a length of 12063.7mm, and roll the steel plate into a cylindrical shape, use penetration welding to weld the joints of the two ends of the rolled steel plate, and correct the weld to make the weld There will be no cracks, air holes and slag inclusions, weld the "ten" or "meter" character reinforcement inside the cylinder, correct the verticality of the outer circle of the cylinder with the welded reinforcement inside and the vertical lathe workbench, and adopt The vertical lathe will rough the end face and outer circle of the workpiece, so that the total length of the workpiece of the casing is 1840mm;

[0067] b. Prepare four right-angle fan-shaped rings with a thickness of 80mm. ...

Abstract

The invention discloses a manufacturing technology of a shell of a wind-driven generator, comprising the following steps: processing the shell firstly, and then processing a rotor, processing an end cover finally and assembling the shell, the rotor and the end cover. The shell of the wind-driven generator is easy to manufacture and is not easy to deform.

Description

Technical field: [0001] The invention relates to a manufacturing process of a wind power generator casing, which is used for manufacturing the wind power generator casing. Background technique: [0002] A wind turbine is a device that converts wind energy into mechanical energy, and the casing of a wind turbine is relatively large in size during production and easily deformed due to its poor strength during processing, resulting in low machining accuracy. , cannot guarantee the quality of the casing of the wind turbine. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a manufacturing process for a wind turbine casing that is easy to manufacture and not easily deformed. [0004] The purpose of the present invention is achieved through the following technical solutions: a manufacturing process of a wind-driven generator casing, comprising the following steps: [0005] 1. Processing of the casing: [0006] A...
