A kind of manufacturing method of drawing mold of aircraft parts of resin-based composite material

Abstract

The invention discloses a manufacturing method for an airplane part stretch-forming mold made of a resin matrix composite and mainly aims to solve the problems that existing molds are large in manufacturing difficulty, hard to store and large in weight and cannot be repaired. The provided manufacturing method for the airplane part stretch-forming mold made of the resin matrix composite comprises the steps that a matrix and a surface are manufactured with the resin matrix composite; and then the airplane part stretch-forming mold is machined and manufactured through a numerical control machine tool. By means of the manufacturing method, the mold using rate is increased, especially, the part productivity is improved, the mold manufacturing cost is reduced, and the mold manufacturing period is shortened.

Description

technical field [0001] The invention relates to a method for manufacturing a drawing die of a resin-based composite material aircraft part, and belongs to the field of die manufacturing. Background technique [0002] Aircraft parts drawing die is one of the key equipment for manufacturing aircraft parts. At present, most of them are made of steel and aluminum. According to the three-dimensional mathematical model designed by the mold, the casting blank made of steel or aluminum is processed on the CNC machine tool. When working, the mold is installed on the stretching machine, and then the blank is clamped, and the stretching machine is started, so that the blank is close to the forming surface of the mold and gradually stretched to the designated position by tension to complete the forming of the part, but it has the following defects: First, The number of manufactured parts is limited. The reason is that after several times of work, due to the influence of friction betwe...

AI Technical Summary

Problems solved by technology

When working, the mold is installed on the stretching machine, and then the blank is clamped, and the stretching machine is started, so that the blank is close to the forming surface of the mold and gradually stretched to the designated position by tension to complete the forming of the part, but it has the following defects: First, The number of manufactured parts is limited. The reason is that after several times of work, due to the influence of friction between the mold surface and the blank, residues will be generated and remain on the mold surface, which is extremely difficult to clean, causing scratches or even scratches on the surface of the parts, resulting in The parts are scrapped; secondly, it is difficult to manufacture the mold because there must be no defects on the forming surface of the mold, such as air holes, sand holes, machining tool marks, etc. Once found, the whole set of molds may be scrapped; in addition, the mold is difficult to store, and must not be rusted during storage. Bumping is absolutely prohibited on the surface, and mold surface defects are found, which cannot be repaired. In addition, the quality is poor, and large parts often reach dozens of tons, which is very unfavorable for handling
