Fiber metal laminated plate forming device and method

Abstract

The invention provides a fiber metal laminated plate forming device and method. A fiber metal laminated plate is processed by means of the hydraulic supporting and auxiliary heating numerical controlincremental forming technology. On a numerical control incremental forming machine tool, a forming tool head controlled through a mechanical program is arranged above a frame-shaped upper forming fixture and a frame-shaped lower forming fixture in advance. A box with an upward opening is additionally arranged in a cavity of the lower forming fixture. The laminated plate is clamped between the upper forming fixture and the lower forming fixture. The box is connected with a pressure control system and a temperature control system through a pipeline. In the process of incremental forming, a hydraulic control system is used for controlling ingoing, outgoing, heating and cooling of hydraulic oil to guarantee that the pressure and temperature borne by the laminated plate to be uniform and constant in the forming process. Accordingly, the good mechanical performance of the laminated plate is guaranteed, and the forming quality of products is improved.

Description

technical field [0001] The invention belongs to the technical field of forming fiber metal laminates, and in particular relates to a forming device and method for fiber metal laminates, which are suitable for forming different types of fiber metal laminates. Background technique [0002] Incremental forming technology adopts the idea of ​​layered manufacturing, divides the overall forming into multiple layers separated by contour lines, each layer is shaped according to a certain trajectory, and the final shape is processed layer by layer. During the forming process, the forming indenter is in partial contact with the sheet metal. Under the action of the forming indenter's force, the small area around the contact point is under pressure and undergoes plastic deformation. On this layer, the layer is produced according to a certain trajectory. The shape is processed, and one layer of processing is completed, and the forming tool is lowered to another layer to continue processi...

AI Technical Summary

Problems solved by technology

[0005] The precision of unsupported mold forming is not high; the problem of uneven deformation of laminates occurs in the ordinary incremental forming process; the problem of uneven heating and difficult maintenance of temperature exists in the existing warm incremental forming; some laminates are difficult to maintain at room temperature. Processing or processing at room temperature The forming performance is unstable and needs to be processed at a certain temperature
