Abstract

An extruding and rolling composite forming device and an extruding and rolling composite forming method of an integral panel skin with ribs belong to processing forming devices and processing forming methods of the integral panel skin with the ribs, and aim at solving the problems that the manufacturing cycle is long, the material utilization rate is low and the forming accuracy is hard to guarantee when an existing integral panel skin with ribs utilizes roll forming and bending forming and the problems that special equipment is needed and the cost is high when peen forming and creep age forming are utilized. The extruding and rolling composite forming device of the integral panel skin with the ribs includes a punch, an extruding container, two cylindrical rollers and two driving mechanisms, wherein two sides of the lower end of a chamber is provided with the two cylindrical rollers, the axes of the two cylindrical rollers are on the same plane, the horizontal distance of the centers of the section circles of the two cylindrical rollers to the vertical center line of the chamber is the same, the side surface on the outer periphery of at least one of the two cylindrical rollers is provided with a plurality of grooves, and each of the cylindrical rollers is connected with one driving mechanism capable of driving the roller to rotate. The extruding and rolling composite forming device and the extruding and rolling composite forming method of the integral panel skin with ribs are applicable to the forming of the integral panel skin with ribs.

Description

technical field [0001] The invention relates to a processing and forming device and method for an integral wall plate with ribs, in particular to an extrusion-rolling composite forming device and method for an integral wall plate with ribs, belonging to the field of plastic processing. Background technique [0002] With the continuous advancement of science and technology, launch vehicles and aircraft are developing towards high speed and high maneuverability. Among them, the integral wall panel is one of the important structures often used in the design of modern aircraft. The processing and manufacturing of integral wall panels is related to the development of the aerospace industry, and has become one of the important symbols to measure the advanced manufacturing level of countries in the world. [0003] Wall panels are usually assembled by riveting, gluing, or spot welding by skin and reinforcements. This assembled structure has poor rigidity, strength, and airtightness,...
