Problems solved by technology

[0003] The factory prefabricated the blade male mold assembly in sections. The existing technology adopts streamlined wing rib templates with sequential numbers that will be cut by CNC machine tools. The top contour curves and shapes gradually change. Positioning, serially numbered one by one and fixed on the basic steel frame, since it is necessary to find the center positioning one by one, the serial assembly efficiency of the blade male mold components is low, labor-intensive and time-consuming, and the cost is high; therefore, now There are problems and deficiencies in existing technologies, such as time-consuming, low efficiency, and high cost

Embodiment Construction

[0022] refer to Figure 1 ~ Figure 3 , a positioning series assembly method of a wind power blade male mold rib formwork of the present invention, comprising a rib formwork 1, a guide steel pipe 2, a basic steel frame 3 and a positioning series assembly method, wherein: the rib formwork 1 It is a streamlined wing-shaped steel sheet template cut by a CNC machine tool, with different top contour curves and shapes. Each wing rib template 1 is marked with a sequence number according to the arrangement and change of the top contour curve shape, which is called a serial number. , the serial number is arranged according to serial number 1, serial number 2~n serial number; the lower part of the wing rib formwork 1 is provided with three circular through holes with a diameter of φ50.2 mm, which are called serial positioning holes 11;

[0023] The guide steel pipe 2 is a circular steel pipe with an outer diameter of φ50 mm and a length of 2.5 meters;

[0024] The basic steel frame 3 is...

Abstract

The invention discloses a fixed position series assembling method of rib templates of a wind turbine blade male mould, which include rib templates (1), a guide steel pipe (2), a foundation steel frame (3) and a fixed position series assembling method. The method includes the steps of: arranging series positioning holes in the rib templates; when assembling the subassemblies of the wind turbine blade male mould in series, locating the centers through a level and welding and fixing the first and fifth rib templates on the foundation steel frame; piloting the centre through the guide steel pipe and then welding and fixing the second, third and fourth rib templates on the foundation steel frame to obtain a standard section; then taking the standard section as a starting point, piloting the centre through the guide steel pipe, and fixing and assembling the remaining rib templates in series piece by piece and section by section. The fixed position series assembling method overcomes the problem and the disadvantage that the conventional method is time-consuming, labor-consuming, low in efficiency and high in cost, and achieves the purposes of saving time and labor, improving the efficiency and reducing the cost in fixed position series assembling of the rib templates of the wind turbine blade male mould.

Description

technical field [0001] The invention relates to a process method for making a male mold of a wind power blade, in particular to a method for positioning and serially assembling a rib template of a male mold of a wind power blade for assembling a rib template of a male mold of a wind power blade. Background technique [0002] The blades of wind power generators are hollow and thin-walled propeller-shaped components supported by a skeleton inside, referred to as wind power blades, and the length of wind power blades can reach 100 meters; such huge components must be manufactured on the wind power site. On site, the blade male mold components prefabricated in sections with a length ranging from 12m to 20m are hoisted and connected in sections to form a complete wind power blade male mold, and then compositely turned on the blade male mold to form the overall blade Then fix the blade female mold on the steel keel skeleton to make composite blade products. The so-called blade ma...
