Processing device of carbon fiber composite material blade grid and blade grid

Abstract

The invention relates to the field of aviation equipment, and in particular to a processing device of a carbon fiber composite material blade grid and the blade grid. The processing device of the carbon fiber composite material blade grid comprises a base and a plurality of machining core molds; the machining core molds are detachably connected with the base, and the machining core molds are of asplit structure. During demolding, the demolding can be achieved through decomposition of the machining core mold; the adverse effect of the structure of holes in the blade grid on the demolding process of the carbon fiber composite material blade grid is reduced, and therefore the holes in the blade grid can be formed at a time in a mold machining process. The invention further provides the bladegrid, and the blade grid is obtained through the processing device.

Description

technical field [0001] The invention relates to aviation equipment, in particular to a processing device for a carbon fiber composite blade cascade and the blade cascade. Background technique [0002] The cascade is an important part of the aircraft. One end in the thickness direction of the cascade is the first surface, and the other end in the thickness direction of the cascade is the second surface. The cascade has a plurality of holes, one end of the holes extends to the first surface, and the other end extends to the second surface. The holes extend along the curve, so that the cascade in the prior art cannot be directly molded. [0003] Aircraft cascades in the prior art are made of metal materials. The manufacturing process is to roughly shape them through a mold first, and then machine the holes on the cascade to finally form the holes so as to meet the structural requirements of the cascade. [0004] With the advancement of technology, there is a large gap between...

Problems solved by technology

However, during the processing of carbon fiber composite cascades, carbon fiber composite materials cannot be machined to form holes

However, if the mold is directly used for molding, the structure of the hole brings difficulties to demoulding, especially for cascades with certain structural holes (for example: the size of each cross section of the hole is equal; or the size of the middle part of the hole is large and close to the two The size of the end is small and other structures), the use of traditional molds will lead to inability to demould
