Rework press assembly for component rework systems and methods of using the same

A component rework system comprising:

• a heat treating enclosure comprising an inner environment configured to receive thermal energy;
• a dimensionally non-conformant component comprising a first material having a first thermal expansion coefficient
• a rework press assembly for reworking the dimensionally non-conformant component, said rework press assembly positioned within said inner environment and comprising:
• a frame comprising a second material having a second thermal expansion coefficient;
• a die comprising a third material having a third thermal expansion coefficient, said die coupled to said frame and configured to contact a first portion of the component;
• and
• a ram coupled to said frame opposite said die with respect to an axis of the rework press assembly, said ram configured to contact a second portion of the component, said ram and said die defining a component cavity therebetween,
• wherein the first thermal expansion coefficient is greater than the second and the third thermal expansion coefficients,
• wherein said ram has a first length, relative to the axis, in response to said rework press assembly being at a first thermal condition, such that a ram gap is defined between the dimensionally non-conformant component and said ram when said rework press assembly is at the first thermal condition,
• wherein said ram has a second length, relative to the axis, in response to said rework press assembly being at a second thermal condition, and wherein the second length is longer than the first length, and wherein the ram gap is at least reduced when said rework press assembly is at the second thermal condition, and
• wherein the second thermal condition occurs at a second temperature that is higher than a first temperature of the first thermal condition,
• wherein at least one of said frame, said die, and said ram comprises a cooling passageway that directs a flow of cooling fluid through said at least one of said frame, said die, and said ram to facilitate controlling differential thermal expansion between at least one of said frame, said die, said ram, and the dimensionally non-conforming component and another of at least one of said frame, said die, said ram, and the dimensionally non-conformant component,
• wherein the differential thermal expansion compresses the dimensionally non-conforming component between said ram and said die.

A method of reworking a component, said method comprising:

• positioning a component comprising a first material having a first thermal expansion coefficient within a component cavity of a rework press assembly, wherein the rework press assembly includes:
• a frame comprising a second material having a second thermal expansion coefficient;
• a die comprising a third material having a third thermal expansion coefficient, the die coupled to the frame and configured to contact a first portion of the component, wherein the first thermal expansion coefficient is greater than the second and third thermal expansion coefficients;
• and
• a ram coupled to the frame opposite the die with respect to an axis of the rework press assembly, the ram configured to contact a second portion of the component, the ram and the die defining the component cavity therebetween,
• wherein the ram has a first length, relative to the axis, in response to the rework press assembly being at a first thermal condition, and wherein a ram gap is defined between the component and the ram when the rework press assembly is at the first thermal condition,
• wherein the ram has a second length, relative to the axis, in response to the rework press assembly being at a second thermal condition, wherein the second length is longer than the first length and wherein the second thermal condition occurs at a second temperature that is higher than a first temperature of the first thermal condition, such that the ram gap is at least reduced when said rework press assembly is at the second thermal condition, and
• wherein at least one of said frame, said die, and said ram comprises a cooling passageway therein;
• and
• positioning the rework press assembly and the component within a heat treating enclosure at the first thermal condition;
• increasing a temperature within the heat treating enclosure until the rework press assembly is at the second thermal condition;
• and
• routing cooling fluid through each cooling passageway to facilitate controlling differential thermal expansion between at least one of said frame, said die, said ram, and the component and another of at least one of said frame, said die, said ram, and the component, wherein the differential thermal expansion compresses the component between said ram and said die.
