Problems solved by technology

Additionally, there exists a need to join standard sized metal sheets together to create one larger sheet with unique dimensions prior to the rotational forming process, but without degrading the material properties of the finished product, e.g. Material properties along the weld

Embodiment Construction

[0050] The present invention will now be described in more detail with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. In fact, the present invention can be implemented in many different ways and should not be limited by the embodiments given in this application; in addition, these embodiments are provided so that the disclosed content can meet the reasonable needs in the application. In the drawings, the same reference numerals designate the same components.

[0051] Figure 1-4 A mandrel 10 according to one embodiment of the invention is shown. Such as Figure 5 As shown, the mandrel 10 of the illustrated embodiment is used for rotational forming of an aircraft engine inlet lip skip 12 . The aircraft engine inlet lip cladding 12 is mounted on the leading edge of a jet engine 14 (eg, an aircraft engine) to direct air into or surround the jet engine 16 during normal operation. Aircraft engine inlet lip cladding 12 ...

Abstract

The present invention provides a mandrel for rotational forming, the mandrel having a backing plate having a removably mounted mandrel portion and mandrel spacers, such that the mandrel is suitable for use in a variety of applications. kind of structure. Different configurations of mandrels may be used to provide different rotationally formed contoured surfaces upon which sheet metal or other rotationally formable material may be rotationally formed. The mandrel also has the ability to join individual metal sheets or multiple metal sheets into the desired rotationally formed product through friction stir welding or other suitable processing processes. The rotationally formed weld metal sheet may be trimmed to remove portions of the weld metal sheet, including the weld seams, that have significantly different material properties as a result of the welding process.

Description

technical field [0001] The present invention generally relates to a mandrel for rotationally forming an article. More specifically, the present invention relates to a single mandrel that is adaptable to a variety of configurations. Background technique [0002] Rotational forming is a way in which flat or hollow materials are reshaped through a point deformation process that utilizes the combined forces of rotation and pressure. Rotational forming involves rotating a product on a lathe and elastically deforming the product on a tool mandrel that rotates with it. By deforming the product on the mandrel, the finished product takes on the contour of the mandrel. In this way, a flat metal sheet can be formed into the desired shape. [0003] A single mandrel can be used to rotationally form many finished products; however, all of these finished products will only have the shape of the single mandrel. As such, multiple mandrels are required to form products of different shapes...
