Abstract

The invention discloses a stirring friction forming device based on self heating. The device comprises a control system, a numerical control forming machine tool, a side pressing mechanism, a stirring head, a supporting mechanism and an infrared thermometer. The stirring head is installed at the tail end of a main shaft of the numerical control forming machine tool and located above a plate material. The supporting mechanism is arranged below the plate material and comprises a forming platform face, a supporting guide column, a transmission mechanism and a supporting rod. The forming platform face is installed on a workbench and can move in the horizontal direction. The supporting guide column is installed on the forming platform face. The transmission mechanism is installed on the supporting guide column. The supporting rod is connected with the transmission mechanism and can be controlled by the transmission mechanism to move in the vertical direction. The supporting rod is located under the stirring head. The infrared thermometer is arranged above the plate material. The plate material forming capability, precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of sheet metal forming, and in particular relates to a friction stir forming device and process based on self-heating. Background technique [0002] Automobile panels (hereinafter referred to as panels) refer to the auto parts that make up the car body or cab, cover the surface and interior of the special-shaped body of the engine and chassis. The car cover is not only a decorative part, but also a closed shell-shaped force-bearing part. The cover part has the characteristics of many curved surfaces, large size, thin material, complex structure and shape, and high precision requirements, and the surface is not allowed to have ripples, wrinkles, edge pull marks and other defects that damage the surface aesthetics, which requires high forming quality. The key link of automobile body manufacturing, its manufacturing technology is difficult, the cost is high, and the development cycle and quality are difficult ...
