Large foam sandwich part forming device and forming method

Abstract

The invention belongs to the field of helicopter rotor part machining, and particularly relates to a large foam sandwich part forming device and forming method. The large foam sandwich part forming device comprises a main die body, a reinforcing base and forming check blocks, the main die body comprises a frame and a face plate, the face plate is welded to the frame structure, longitudinal partition plates and transverse partition plates are welded together in a crossed mode, and square holes for reducing weight are formed in the partition plates. According to the device, a square base plate is arranged at the bottom of the frame structure and used for being connected with the reinforcing base, the reinforcing base is of a trapezoidal frame structure, reinforcing ribs are arranged in the middle, a square base plate is arranged on the upper surface, the forming check blocks are divided into a main forming check block 3 and left and right gluing check blocks, and the forming check blocksare arranged at the part positions in the forming process so as to carry out positioning forming.

Description

technical field [0001] The invention belongs to the field of processing helicopter rotor parts, and in particular relates to a molding device and a molding method for large foam interlayer parts. Background technique [0002] Due to the large size of the large foam sandwich parts, the length is more than 4 meters, and it is difficult to form. Especially for large foam sandwich parts for helicopter rotors, due to the structural specificity and the strength requirements of the parts, and the relatively large size, it is different from the molding method of small and medium-sized foam sandwich parts. The processing technology of large foam sandwich parts is difficult and prone to defects, and requires The molding device of the present invention has complex structure and high cost, which is a practical technical problem. Contents of the invention [0003] The technical problem to be solved by the present invention is: by proposing a molding device and molding method for large...
