Embodiment Construction

[0020] A method for manufacturing a wind power product and a water turbine blade mold is characterized in that it comprises the following steps:

[0021] a. Selection of formwork material: According to the specific size of the formwork and the specific force requirements in the later modeling process, select hot-rolled channel steel and I-beam;

[0022] b. Three-dimensional software for structural design and force simulation: convert the two-dimensional formwork drawing into a three-dimensional figure and perform force simulation in the simulation software, so as to obtain the force status of the steel formwork and the bending change of the formwork. Based on the simulation results, the middle gap of the formwork Optimize the retaining distance and the design of adding ribs at the four corners;

[0023] c. Welding: According to the steel template material is Q235 structural steel, all welding rods are J422 structural steel welding rods, the average temperature of the molten po...

Abstract

The present invention relates to a method for manufacturing a mould, especially to a method for manufacturing a blade mould of a wind power product and a hydraulic turbine. The method is characterized by comprising the following steps of choosing mould board materials, carrying out structure design and force simulation via a three dimensional software, welding, destressing, designing and installing a steel mould board accessory structure, and laying board. The method has a unique technique, produces a firm and durable mould and satisfies design precision, and by the research and application of new materials and new methods in mould making process, the method solves the deformation problem of the mould and guarantees the size precision of the wind power mould.

Description

technical field [0001] The invention relates to a method for manufacturing a mold, in particular to a method for manufacturing a mold for a wind power product and a water turbine blade. Background technique [0002] The 21st century is the century of renewable energy. The whole world is concerned about the increasing atmospheric temperature, and every country is studying how to reduce the carbon content in energy. At the beginning of 2003, the global wind power generator capacity reached 32 million kilowatts. It is estimated that in the next 20 years, my country's wind power will develop at a rate of 20%-30%; and the hydroelectric generator is a device that converts the kinetic energy generated by the flow of water into electrical energy. It is also a renewable resource that does not pollute the environment. growing stronger in the field. Whether it is a hub in a wind turbine, a foundation or a turbine blade in a water turbine, they are all large castings, which impose stri...
