Abstract

The present invention discloses a method for manufacturing a slide gate, involving providing a gate body with a first face and integrally forming an integral gate seal with the gate body through a hybrid manufacturing process. The hybrid manufacturing process includes depositing an additive material onto the first face of the gate body to create the integral gate seal, with the deposition carried out by a first machine. Subsequently, the integral gate seal is machined to achieve the desired size and shape, with the machining also performed by the same first machine. This method combines additive manufacturing and machining techniques to efficiently produce slide gates with integral gate seals of precise dimensions and configurations.

Claims (29)

1 . A method of manufacturing a slide gate, the method comprising:

providing a gate body defining a first face; and

integrally forming an integral gate seal with the gate body by a hybrid manufacturing process, wherein the hybrid manufacturing process comprises:

depositing an additive material onto the first face of the gate body, the additive material forming the integral gate seal, wherein depositing the additive material onto the first face is performed by a first machine; and

machining the integral gate seal to a desired size and shape, wherein machining the integral gate seal is performed by the first machine,

wherein:

the integral gate seal comprises a first gate seal segment and a second gate seal segment substantially parallel to the first gate seal segment, the first gate seal segment and the second gate seal segment each defines a gate seating face, and

the integral gate seal further comprises a lateral gate seal segment extending between the first gate seal segment and the second gate seal segment, and wherein the lateral gate seal segment defines a gate seating face.

2 . The method of claim 1 , further comprising cutting a first gate rough region and a second gate rough region onto the first face prior to integrally forming the integral gate seal with the gate body, wherein the first gate rough region and the second gate rough region are defined at target locations on the first face, and the first gate seal segment is integrally formed with the gate body at the first gate rough region and the second gate seal segment is integrally formed with the gate body at the second gate rough region.

3 . The method of claim 2 , wherein cutting the first gate rough region and the second gate rough region onto the first face is performed by the first machine.

4 . A method of manufacturing a slide gate, the method comprising:

providing a gate body defining a first face; and

forming a gate seal with the gate body, comprising:

forming the gate seal by depositing an additive material onto a face of the gate body with a machine; and

machining the gate seal to a desired size and shape with the machine,

wherein:

the gate seal comprises a first gate seal segment and a second gate seal segment substantially parallel to the first gate seal segment, each of the first gate seal segment and the second gate seal segment define a gate seating face, and

the gate seal further comprises a lateral gate seal segment extending between a first gate seal segment and a second gate seal segment, the lateral gate seal segment defines a gate seating face.

5 . The method of claim 4 , further comprising cutting a first gate rough region and a second gate rough region onto the face prior to forming the gate seal with the gate body, wherein the first gate rough region and the second gate rough region are defined at target locations on the first face, and wherein the gate seal comprises a first gate seal segment formed with the gate body at the first gate rough region and the gate seal comprises a second gate seal segment is formed with the gate body at the second gate rough region.

6 . The method of claim 5 , wherein cutting the first gate rough region and the second gate rough region onto the face is performed by the machine.

7 . A method, comprising:

forming a gate seal with a gate body defining a face, comprising:

depositing an additive material to form the gate seal on the face of the gate body; and

machining the gate seal to a desired size and shape,

wherein:

the gate seal comprises a first gate seal segment and a second gate seal segment substantially parallel to the first gate seal segment, the first gate seal segment and the second gate seal segment each define a gate seating face, and

the gate seal further comprises a lateral gate seal segment extending on the gate seal between a first gate seal segment and a second gate seal segment, and wherein the lateral gate seal segment defines a gate seating face.

8 . The method of claim 7 , further comprising cutting a first gate rough region and a second gate rough region on the face prior to integrally forming the gate seal with the gate body, wherein the first gate rough region and the second gate rough region are defined at target locations on the face, and wherein the gate seal defines a first gate seal segment integrally formed with the gate body at the first gate rough region and a second gate seal segment integrally formed with the gate body at the second gate rough region.

9 . The method of claim 8 , wherein cutting the first gate rough region and the second gate rough region onto the face is performed by a machine capable of depositing an additive material to form the gate seal on the face of the gate body and machining the gate seal to the desired size and shape.
