Abstract

The invention relates to an improvement of a wind power shaft production technology. The improved production technology comprises the following steps: preparing steel ingot raw materials, charging, heating, forging and stamping, normalizing, tempering, annealing and cooling, examination and correction, rough machining, quenching, milling, finishing machining to obtain finished products, wherein in the heating step, the highest temperature of a workpiece is controlled to 910-930 DEG C by using fuzzy intelligent temperature control; and in the quenching step, the water temperature in a quenching bath is controlled to 20-40 DEG C by using quenching bath water temperature intelligent control. According to the invention, the heating temperature can be effectively controlled, the water temperature intelligent control in the heating furnace and the quenching bath can be realized, the resistance to fatigue and crack prevention property of the wind power shaft are raised, and the service life of the wind power shaft is prolonged.

Description

(1) Technical field [0001] The invention is an improvement to the production process of the wind power shaft. (2) Background technology [0002] Wind power is a renewable, non-polluting, high-energy, and promising energy source. It is a strategic choice for all countries in the world to vigorously develop clean energy. Wind power technology and equipment is an important part of the wind power industry, as well as the foundation and guarantee for the development of the wind power industry. In the conventional wind turbine shaft production process, the temperature control of the heating furnace is not accurate; when quenching, the water temperature in the quenching pool is not controlled. [0003] The quality of the wind power shaft affects the performance and quality of the entire wind power equipment, and fatigue and cracks are common problems in wind power shafts. The main reasons for fatigue cracking of wind turbine shafts are: [0004] 1. The temperature heating in the...
