Pre-bending Tooling and Shot-peening Forming Method for Integral Wall Panel with Ribs

Abstract

The invention discloses a pre-bending tool for integral wall panels with ribs, which comprises a support column, a force application column, a top wire, a rib top block and a backing plate; When placing the integral wall panel with ribs, the rib top block is located between the force-applying column and the integral wall plate with ribs and is in contact with the ribs of the integral wall plate with ribs. Contact; the first end surface of the backing plate is in contact with the rib, and the second end surface of the backing plate is in contact with the top block of the rib. The invention also discloses a shot peening forming method. The purpose of the pre-bending tooling for integral wall panels with ribs is to solve the problem that the part's spanwise pre-bending surface is not smooth due to the discontinuous contact position between the tooling and a certain rib of the part, which affects the shot peening accuracy and surface quality of the part.

Description

technical field [0001] The invention belongs to the technical field of shot-peening forming of aircraft sidings, and in particular relates to a pre-bending tool for integral siding with ribs and a shot-peening forming method. Background technique [0002] Shot peening technology uses high-speed shot blasting to hit the surface of the metal plate, causing the impacted surface and its underlying metal material to undergo plastic deformation and elongate, so that the plate is gradually bent and deformed toward the sprayed surface to achieve the desired shape. a forming method. This technology began in the early 1950s and gradually developed with the wide application of aircraft integral panel parts. Because this forming method does not require special molds and presses in the forming process, the forming method is flexible and diverse, and is very suitable for small batch production. Therefore, it is widely used in the overall wall panels of aircraft wings, fuselages and launc...

AI Technical Summary

Problems solved by technology

When applying pre-bending to the ribs of the overall wall plate with large curvature and ribs, the contact position between the tooling and a certain rib of the part is discontinuous, which causes the pre-bending surface of the part to be unsmooth, thus affecting the shot peening accuracy and surface quality of the part

[0006] In view of this, those skilled in the art urgently need to provide a pre-bending tooling and shot blasting forming method for integral wall panels with ribs to solve the problem that the part is not smooth in the span direction of the pre-bending surface due to the discontinuous contact position between the tooling and a certain rib of the part. This will affect the accuracy and surface quality of parts shot peening
