Description

Ultrasonic-assisted incremental forming device and process for aluminum alloy ribbed thin-walled components

technical field

The invention relates to the technical field of machining, in particular to an ultrasonic-assisted incremental forming device and a process for an aluminum alloy ribbed thin-walled component.

Background technique

Ribbed thin-walled panels are components widely used in aerospace and other high-precision fields. They are not only frequently used in the composition of aircraft shells, but also widely used in the main load-bearing parts of aircraft such as wings and even in space stations. The rigidity and strength can also greatly reduce the structural mass. Therefore, the manufacturing and deformation processing technology of ribbed thin-walled plates occupies an important position in the field of lightweight and high-strength metal manufacturing, and the importance of its development and innovation is self-evident. Because of its high quality requirements, it is usually made of aluminum alloys, magnesium alloys, and titanium alloys with high strength, but at the same time it requires that it can be processed into a more complex curvature, and at the same time, it cannot be directly deformed because of the attached ribs. In order to achieve the required shape and curvature, it is usually necessary to treat the thin-walled plate and the rib as a whole for plastic bending deformation. However, in the previous processing of ribbed thin-walled plates, extrusion forming, creep forming, roll forming, welding forming and other technical means were mostly used. However, technologies such as creep failure have the disadvantages of complex deformation process, bulky equipment, difficult manual processing, and difficulty in forming; the quality of roll bending and extrusion technology is not high, often with various defects, and the production efficiency is low. It is unable to meet the large-scale and mass production of ribbed thin-walled panels, and the demand cannot be met in a short period of time. There is no doubt that we should continue to look for a new process that can integrally process ribbed thin-walled panels and seek innovation.

At present, the single-point incremental forming process for thin-walled plates is mostly limited to flat plates, and there are few new process outputs that can directly or use auxiliary means to process ribbed thin-walled plates as a whole. The patent with the publication number of CN104690138A entitled "A Magnesium Alloy Sheet Ultrasonic Vibration Single Point Incremental Forming Device and Its Incremental Forming Method" discloses a magnesium alloy sheet ultrasonic vibration single point incremental forming device and its incremental forming method. Applied to single point incremental forming.

The ordinary ribbed plate processing technology aggravates the unevenness of the force in the components because the ribs and the wall plate are subjected to the upper and lower extrusion force at the same time, and it is very easy to produce wrinkles, warping, side bending and other defects in the ribs and the wall plate. In the article "Research on Roll-Bending Forming Process of Integral Wall Plate Filler", Zhang Xinhua described a first-fill and then roll-bending processing technology for ribbed thin-walled plates. The patent with the publication number of CN109877211A entitled "A Method for Electromagnetic Forming of Ribbed Wall Plate Filler" discloses a kind of electromagnetic forming method for ribbed wall plate filler. In the process of electromagnetic forming, a reasonable forming station is determined, and the overall processing of the ribbed thin-walled plate is finally completed. However, this method is used for extrusion molding. If it is used in single-point incremental molding, there will be a height difference between the filler and the rib due to the material difference, which will lead to inability to process. Disadvantages such as uneven application of each point of the component.

Considering that neoprene has good physical and mechanical properties, It has high tensile strength, elongation and reversible crystallinity. It has good adhesion, aging resistance and heat resistance. At the same time, considering the cost of using metal fillers, sulfur-adjusted neoprene rubber is specially used. After the filling is completed, an aluminum alloy cladding plate 18 with a specific thickness is added on it again to create a smooth surface to complete the incremental forming work, and at the same time reduce the compression deformation of the rubber and reduce the uneven force of the blank.

Next, the complete aluminum alloy ribbed thin-walled plate to be processed is clamped in the device clamp; by rotating the adjusting bolt 56, the upper clamp plate 54 is driven to move closer to the lower clamp plate 55, and the workpiece to be processed is clamped. The two stepping motors 22 on the worktable 2 run synchronously to move the moving plate 24 directly below the tool head 11; the two motors in the clamping device 5 run synchronously to adjust the angle of the workpiece to be processed; the vertical cylinder 30 is synchronous The shrinkage drives the beam and the mounting structure on it to descend as a whole, and the tool head 11 contacts the workpiece to be processed.
