Abstract
The invention discloses a friction riveting device for a thermoplastic carbon fiber composite material and an aluminum alloy. The friction riveting device comprises a female die, a blank holder and a driving rod. The lower part of the female die is of a solid cylindrical structure, the center of the upper part of the female die is provided with a circular groove, and the bottom face of the circular groove protrudes upwards to form a conical shape. The blank holder is of a cylindrical structure, a cylindrical center hole is formed in the center of the blank holder, and the blank holder is arranged above the female die and is coaxial with the female die. The driving rod is coaxially arranged in the center hole and can perform rotary motion and axial feeding motion along the center hole. The invention further discloses a riveting method of the friction riveting device for the thermoplastic carbon fiber composite material and the aluminum alloy, heat is generated through rotating friction, meanwhile, the rotating speed and the axial feeding speed of the rivet are adjusted, and therefore the optimal rivet welding state value between the thermoplastic carbon fiber composite material plate and the aluminum alloy plate can be achieved, and the joint strength and the joint forming effect are improved.
Description
technical field [0001] The invention relates to the technical field of riveting of a thermoplastic carbon fiber composite material plate and an aluminum alloy plate, and more specifically, the invention relates to a friction riveting device and a riveting method for a thermoplastic carbon fiber composite material and aluminum alloy plate. Background technique [0002] Under the requirements of automobile lightweight, composite materials and light alloy materials are used as the main lightweight materials in light structure products.
