Example Embodiment

[0029] Such as figure 1 As shown, the specific process is as follows:

[0030] 1. A manufacturing process of a shear rib mould, characterized in that it comprises the following steps:

[0031] (1), puzzle, stakeout

[0032] After putting the 1.5m X 2.5m cold-rolled board into a plane, place the finished shear ribs on the plane;

[0033] (2), metal folding

[0034] Fold the placed cold-rolled board into a right angle to make the flanging of the shearing rib, and use the newly-added L-shaped board to lean on the finished product of the shearing rib, a section of 1 meter, such as figure 2 As shown, the flanging size is determined according to the size of the finished shear rib, the flanging width is 20 cm and the height is 9 cm;

[0035] (3), welding plate

[0036] Use an electric welder to weld the gaps between the cold-rolled plates after folding;

[0037] (4), welding seam pressure

[0038] Keep pressure on each weld of the flat plate, first paste the sealing doctrine at the weld position,...

Abstract

The invention discloses a manufacturing process of a shearing rib mold, which is characterized by comprising the following steps: (1) splicing plates, and lofting; (2) folding a metal edge: folding a steel plate into a right angle at the edge of the steel plate to manufacture the edge of a shearing rib, and ensuring the angle; (3) welding a flat plate; (4) maintaining pressure of welded seams; (5) manufacturing an inner cavity of the mold; (6) laying heating strips; (7) laying heat-insulating cotton; and (8) adjusting the level of the mold. In the invention, the problems that in the prior art, the shearing rib mold is manufactured by adopting glass fiber reinforced plastics, the cost is high, and the shrinkage rate and the deformation rate of the finished mold are higher are solved. The invention provides the manufacturing process for manufacturing the shearing rib mold by using the steel plate as a raw material.

Description

Technical field [0001] The invention relates to a mold manufacturing process, in particular to a cutting rib mold manufacturing process. Background technique [0002] At present, there are many kinds of molds used to make FRP, such as wooden molds, silicone molds, plaster molds, FRP molds, steel molds, etc. The method of making FRP molds: Lay FRP cloth, and then lay copper pipes for heating, mix resin and aluminum powder evenly, spread on it, and then spread a layer of FRP cloth. FRP molds include female molds, male molds, paired molds, etc. The specific inner type to be selected depends on the structure, process, and quality requirements of the product. First of all, the original part is the male mold. In the past, most of them were made of wood in China. However, for wind turbine blades of this length, most foreign countries use paste wood instead of wood to construct and use machines to operate. Then turn the negative film on this male mold, and after the parting surface is ...
