Problems solved by technology
[0007] In this method of making the shear rib male mold, the prerequisite for the initial shape of the shear rib male mold is to make the blade shell first. In the production cycle, the production time of the blade shell is long, and it takes a long time. The initial shape of the shear rib male mold can only be pressed after the blade shell is made, and the production cycle is longer; in terms of cost, more raw materials are required to manufacture the blade shell, resulting in waste of raw materials and higher production costs

Embodiment Construction
[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Please see image 3 , image 3 It is a flowchart of a specific embodiment of the method for manufacturing the shear rib male mold provided by the present invention.
[0037] Such as image 3 As shown, the manufacturing method of the shear rib male mold provided by the present invention may include the following steps.
[0038] Step 101, laying the simulation layer of the blade shell. The first blade shell simulation layer 2-1 equal to the thickness of the blade shell is laid at the shear rib bonding place of the working surface mold 1-2 of the blade mold 1, and the shear rib of the aerodynamic surface mold 1-1 of the blade mold 1 is laid. A second blade shell simulation layer 2-2 equal to the thickness of the b...

Abstract
The invention relates to the technical field of wind power generation, in particular to a manufacture method of a shearing rib male die. The manufacture method of the shearing rib male die comprises the following steps of: respectively paving a first blade shell simulation layer and a second blade shell simulation layer which have the same thickness with a blade shell at the shearing rib adhesion parts of a pneumatic surface die and the shearing rib adhesion parts of a working surface die of a blade die; adhering and fixing a prototype of the shearing rib male die onto the upper surface of the first blade shell simulation layer or the second blade shell simulation layer; fixing one of the pneumatic surface die and the working surface die, turning over the other; and closing the die and profiling the shearing rib male die. The invention also discloses the shearing rib male die made by using the manufacture method of the shearing rib male die, as well as a shearing rib female die and blades made by the shearing rib male die.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for manufacturing a shear rib male mold for fan blades. The present invention also relates to a shearing rib male mold made by the above-mentioned shearing rib male mold manufacturing method, a shearing rib female mold formed by turning over the above shearing rib male mold, and a shearing rib formed by the above-mentioned Blades made from shear rib female moulds. Background technique [0002] A wind turbine is a new energy power machine that converts wind energy into mechanical energy. The wind turbine uses wind power to drive the blades to rotate, and then increases the speed of rotation through a speed increaser to drive the generator to generate electricity. [0003] The enlargement of wind turbines is a trend in the utilization of wind energy in the world at present, and many countries such as Germany, Denmark, the United States and Sweden are devotin...
