Problems solved by technology

But at this time, the chassis of the mold shell 1 and the wax pattern 2 easily form a deformed gap region one 4 when separating, and between the wax pattern 2 and the aluminum plate 3 also easily form a deformed gap region two 5 when separating. The superposition eventually results in deformation of the chassis of Form 1

Embodiment Construction

[0022] Embodiments of the invention are described in detail below, but the invention can be implemented in a number of different ways as defined and covered by the claims:

[0023] Such as figure 2 As shown, the present invention provides a method for preventing the deformation of the large-size directional blade shell chassis, which is characterized in that: it includes the following steps:

[0024] S1: Fix the aluminum plate 3, and the aluminum plate 3 is fixed by a manipulator;

[0025] S2: Modify and fix the aluminum plate 3, wherein, on the upper surface of the aluminum plate 3, there are a plurality of undercuts a integrated with the aluminum plate 3, and the undercut a is a tooth-shaped structure, which can prevent the wax mold to be made on the aluminum plate 3 2 Move and separate so that the wax mold 2 causes deformation, and the interval between every two undercuts a is 65mm;

[0026] S3: making a wax mold 2 on the aluminum plate 3, according to step S2, the heigh...

Abstract

The invention discloses a method for preventing a chassis of a large-size directional blade shell from deforming. The method comprises the following steps that S1, an aluminum plate is fixed, S2, thefixed aluminum plate is modified, a plurality of inverted buckles integrated with the aluminum plate are arranged on the upper surface of the aluminum plate, and the interval between every two inverted buckles is larger than 60 mm, S3, a wax mold is manufactured on the aluminum plate, and according to the step S2, the inverted buckling height is two thirds of the height of the wax mold, S4, reinforcing ribs are arranged in the area, away from the blade, of the wax mold, and the height of the reinforcing ribs is larger than the thickness of the wax mold, and S5, slurry hanging and sand sprayingare conducted on the wax mold so that a shell is formed. The method is ingenious in design, and deformation of a chassis of the mold shell during mold shell preparation is prevented.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a method for preventing deformation of a chassis of a large-size directional blade shell. Background technique [0002] In the process of preparing large-scale directional blade shells, existing technologies such as figure 1 As shown, the aluminum plate 3 is used as a manipulator for clamping and fixing, and the wax mold 2 is connected to the aluminum plate 3 , and the mold shell 1 is formed by hanging slurry and sanding on the wax mold 2 . But this moment, between the chassis of the mold shell 1 and the wax mold 2, a deformed gap zone one 4 is easily formed between the wax mold 2 and the aluminum plate 3, and a deformed gap zone two 5 is also easily formed between the wax mold 2 and the aluminum plate 3, and the two deformations The superposition eventually leads to deformation of the chassis of the form 1 . [0003] Therefore, it is necessary to design a meth...
