Technical Field

[0001] The utility model belongs to the technical field of part flanging processing devices, and particularly relates to a structure for graphite seal rolling flanging. Background Art

[0002] For aviation parts, such as graphite components, a protrusion is axially arranged on one side surface, and the protrusion needs to be processed by flanging. The existing method adopts a semi-artificial + semi-mechanical processing method. During the processing, the surface of the part is prone to scratches, and there are depressions at the flanging points after flanging, resulting in slight deformation of the part size and reducing the efficiency of part flanging processing. Content of the Utility Model

[0003] In view of this, the structure for graphite seal rolling flanging provided by the utility model solves the technical problem that the existing structure reduces the efficiency of part flanging processing.

[0004] A structure for graphite seal rolling flanging is installed on the working shaft of a rolling press and is applicable to flanging processing of protrusions on parts. It includes a flanging assembly, and the flanging assembly is installed on the working shaft. When the rolling press works, the protrusion is pressed down by the flanging assembly to complete the flanging processing of the part.

[0005] Preferably, the working shaft includes an upper shaft and a lower shaft arranged at intervals. Among them, when the rolling press works, the upper shaft and / or the lower shaft are driven to move towards each other, and the upper shaft and / or the lower shaft are driven to rotate, and the protrusion on the part is flanged by the flanging assembly.

[0006] Preferably, the flanging assembly includes a flanging rolling wheel arranged in a cylindrical structure and a clamping assembly. The flanging rolling wheel is installed on the upper shaft, and the clamping assembly is installed on the lower shaft for fastening the part. Among them,

[0008] Preferably, a rolling ring ear or a rolling step is arranged on the outer circumference of the flanging rolling wheel, and the protrusion on the part is flanged by the rolling ring ear or the rolling step.

[0009] Preferably, the clamping assembly includes a positioning roller arranged in a stepped structure and a pressing and supporting roller arranged in a stepped structure. The positioning roller is installed on the lower shaft, and the part is nested on the stepped surface of the positioning roller;

[0010] The pressing and supporting roller is installed on the lower shaft to fasten the part installed on the positioning roller and prevent the part from shaking or moving during the processing.

[0011] Beneficial effects

[0012] By setting up the flanging component to replace the traditional semi - manual flanging processing method, the force on the part during rolling is small, the control is stable, the surface of the part will not be scratched, and there is no depression at the flanging point after the part is flanged, and the size is stable, thus improving the processing efficiency.

[0023] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the aspects can be practiced without these specific details.

[0024] As Figures 1 to 4 shown, the structure of the graphite seal rolling and flanging is installed on the working shaft of a rolling press in the prior art. The working shaft includes an upper shaft 1 and a lower shaft 2 arranged at intervals, and is suitable for flanging the protrusion 20 on a part. For the protrusion 20, refer to Figure 2 shown. The rolling press is configured with a controller that can control the rotation speed and the moving distance of the upper shaft 1 and the lower shaft 2. It includes a flanging assembly, and the flanging assembly is installed on the working shaft. When the rolling press works, the protrusion is pressed down by the flanging assembly to complete the flanging process of the part. Among them, when the rolling press works, it drives the upper shaft 1 and / or the lower shaft 2 to move towards each other, and drives the upper shaft 1 and / or the lower shaft 2 to rotate, and the protrusion on the part is flanged by the flanging assembly.

[0025] As a specific implementation manner provided in this case, the flanging assembly includes a flanging roller 7 arranged in a cylindrical structure and a clamping assembly. The flanging roller 7 is installed on the upper shaft 1 and is fixed by a fastening nut. The clamping assembly is installed on the lower shaft 2 and is used to fasten the part. Among them, when the upper shaft 1 moves towards the lower shaft 2, the part clamped by the clamping assembly is flanged by the flanging roller 7. Specifically,

[0026] The outer circumference of the flanging roller 7 is provided with a rolling ring ear 6 or a rolling step, and the protrusion on the part is flanged by the rolling ring ear 6 or the rolling step.

[0027] Further, referring to Figure 3 As shown, the clamping assembly includes a positioning roller 3 arranged in a stepped structure and a pressing and supporting roller 4 arranged in a stepped structure. The positioning roller 3 is installed on the lower shaft 2, and the part is nested on the stepped surface of the positioning roller 3. The pressing and supporting roller 4 is installed on the lower shaft 2 and fixed by a nut. Preferably, the lower shaft 2 is provided with an external thread, and the pressing and supporting roller 4 and the positioning roller 3 are installed on the lower shaft 2 in a threaded manner to fasten the part installed on the positioning roller 3 and prevent the part from shaking or moving during the processing.

[0028] Further, the thickness of the rolling ring ear 6 or the rolling step is less than the length of the stepped surface of the pressing and supporting roller 4, ensuring that one side of the rolling ring ear 6 or the rolling step contacts the raised portion 20 after flanging, and the other side does not contact the pressing and supporting roller 4, reducing the wear of the component. Also, the radius of the stepped portion of the positioning roller 3 is less than the radius of the stepped portion of the pressing and supporting roller 4, ensuring that the part can be stably clamped.

[0029] Further, a filling step 5 arranged in a ring structure is provided on the outer ring surface of the pressing and supporting roller 4 near the side surface adjacent to the positioning roller 3. The side surface of the filling step 5 away from the positioning roller 3 is arranged in an arc-shaped fillet structure. Preferably, the angle of the arc-shaped fillet is 90°. The filling step 5 can support the root of the raised portion. When the rolling ring ear 6 or the rolling step presses down the raised portion, with the rotation of the lower shaft 2, the raised portion 20 is completely attached to the side surface with the arc-shaped fillet provided on the filling step 5, completing the flanging process of the raised portion.

[0030] During processing: Start the rolling machine. The rolling ring ear 6 slowly presses down until it is about to contact the pressing and supporting roller 4, then the rolling ring ear 6 stops pressing down. After the lower shaft 2 rotates more than one circle, the flanging process can be completed. Then the upper shaft 1 drives the rolling ring ear 6 to slowly withdraw upward. The advantages are: the force during rolling is small and the control is stable, the surface of the part will not be scratched, and there is no depression at the flanging point of the part after flanging and the size is stable.

[0031] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present disclosure should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
