Embodiment Construction

[0011] The riveting equipment 1 used in this embodiment is the electromagnetic riveting equipment currently used in production, and the top iron 6 is also a conventional tool used in production. First make rivet holes 4 on the composite material plate 3 according to the diameter of the rivets, and the hole making tools and hole making requirements are in accordance with HB / Z223.21‐2003 Aircraft Assembly Process Part 21 Riveting of composite materials; select titanium niobium rivets and titanium alloy pads Electromagnetic riveting equipment is used to select the appropriate riveting voltage for riveting. The aperture size of the rivet hole is the diameter of the rivet plus 0.1mm, not exceeding the diameter of the rivet plus 0.2mm; the inner diameter of the gasket is the diameter of the rivet plus 0.1mm, not exceeding Add 0.2mm to the diameter of the rivet; the thickness of the gasket is 0.8mm to 1.0mm. The aperture size is generally the diameter of the rivet plus 0.1mm to 0.2mm...

Abstract

The invention discloses a process method for achieving an electromagnetic riveting composite material. The method mainly resolves the problem that when riveting is carried out through a traditional riveting method at preset, the composite material is damaged easily. The process method for achieving the electromagnetic riveting composite material adopts the electromagnetic riveting technology, and largely reduces the installation damage to the structure of the composite material in the riveting process through a specially designed gasket and an appropriate tack hole interval and rivet overhang, thereby improving the quality of connectors.

Description

technical field [0001] The invention relates to a process method for riveting composite material structures in the technical field of aviation manufacturing, in particular to a process method for electromagnetic riveting composite materials. . Background technique [0002] In the field of aerospace, riveting has more advantages than screwing due to its simple process and light structure, and is a very widely used process method. Composite materials are being used more and more widely in the aerospace field due to their many advantages. However, the interlayer strength of composite materials is low. When ordinary hammer riveting is used, the composite material structure is often easily damaged due to the uneven expansion of the nail rod; or the impact damage to the composite material structure is caused by the impact of hammer riveting. [0003] Electromagnetic riveting is an advanced riveting process. It is an impact loading with zero impact distance and has little impact ...
