Abstract
A core pattern reformer system for adjusting and setting a core pattern for use in casting a gas turbine blade has a first portion having a first internal face with a concave portion. The first portion is coupled to a second portion. The second portion has a second internal face with a convex portion. A plurality of adjustable pins is positioned along the internal faces of the first portion and the second portion. The pins have a height that is adjustable with respect to the internal faces. A locking mechanism is included for securing the first portion to the second portion. The system includes one or more air inlets and one or more air exits and a source of cooling air coupled to the one or more air inlets.

A reforming tool for a core pattern comprising:
- a first portion having a first internal face with a concave portion;
- a second portion having a second internal face with a convex portion;
- a plurality of adjustable pins extending away from the first and second internal faces, the pins having a height that is adjustable with respect to the first and second internal faces;
- a locking mechanism for securing the first portion to the second portion;
- one or more air inlets;
- and,
- one or more air exits;
- wherein the core pattern is supported and repositioned within the reforming tool by the plurality of adjustable pins and is cooled by air passing through the reforming tool.
A method of reforming a core pattern comprising:
- providing the core pattern corresponding to an internal profile of a turbine blade core;
- adjusting one or more pins of a core reforming tool, the core reforming tool having a first portion with a concave portion and a second portion with a convex portion;
- positioning the core pattern in the core reforming tool;
- closing the core reforming tool such that the second portion is moved towards the first portion;
- and,
- directing cooling air through the core reforming tool and solidifying the core pattern.
A system for adjusting and setting a core pattern for use in casting a gas turbine blade, the system comprising:
- a first portion having a first internal face with a concave portion, the first portion coupled to a second portion, the second portion having a second internal face with a convex portion;
- a plurality of adjustable pins positioned along the internal faces of the first portion and the second portion, the pins having a height that is adjustable with respect to the internal faces;
- a locking mechanism for securing the first portion to the second portion;
- one or more air inlets and one or more air exits;
- and,
- a source of cooling air coupled to the one or more air inlets.
