(V) Specific implementation methods

[0022] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a main frame 2 installed on the top of the plate rolling machine frame 1, a cantilever beam 3 that can be lifted and lowered along the main frame 2 is provided on the left side of the main frame 2, a roller 4 is hinged on the left end of the cantilever beam 3, a support 5 is connected below the cantilever beam 3, and a cantilever beam 6 is connected below the support 5. The right end of the cantilever beam 3 is connected to one end of a chain 7, and the other end of the chain 7 is fixed to the main frame 2 after being wound on a sprocket 8, and the sprocket 8 is installed on the top of the first lifting cylinder 9. The support 5 is connected to the end of the second lifting cylinder 10, and the second lifting cylinder 10 is connected to the bottom of the cantilever beam 3. A stopper wheel 11 is installed on the right end of the cantilever beam 3. A fixing frame 12 is connected between the right side of the main frame 2 and the plate rolling machine frame 1.

[0023] The wide range upper support device for plate rolling machine of the utility model is adopted, and the second lifting cylinder 10 is hinged with the support 5 through the pin shaft. Through the lifting and lowering of the first lifting cylinder 9, the chain 7 can drive the cantilever beam 3 to rise and fall along the main frame 2. The first lifting cylinder 9 is equipped with a pressure sensor. When the cylinder pressure reaches a limited value, the lifting cylinder stops rising and rolls a large-diameter cylinder. The support 5 is connected to the cantilever beam 3 and the cantilever beam 6 through bolts, and the second lifting cylinder 10 can drive the cantilever beam 6 to rise and fall. The second lifting cylinder 10 is equipped with a pressure sensor. When the cylinder pressure reaches a limited value, the second lifting cylinder 10 stops descending and rolls a small-diameter cylinder.

[0024] When supporting the rolling of a small-diameter workpiece, the first step is to lower the second lifting cylinder 10, driving the cantilever beam 6 to lower. The second step is to allow the small-diameter cylinder to pass through the opening of the cantilever beam 6, and the lower part of the opening of the cantilever beam 6 contacts the inner wall of the cylinder, so that the cantilever beam 6 plays a supporting role. The third step is to operate the plate rolling machine to complete the rolling of the workpiece with the assistance of the small-diameter rolling support device. The fourth step is to remove the workpiece and then raise the second lifting cylinder 10, driving the cantilever beam 6 to rise, and return to the initial position to wait for the next workpiece to be rolled.

[0025] When supporting the rolling of a large-diameter workpiece, the first step is: the first lifting cylinder 9 rises, and drives the cantilever beam 3 to move upward along the main frame 2 through the chain 7. The second step is: when the cantilever beam 3 moves upward to the roller 4 and contacts the inner wall of the large-diameter workpiece, the roller 4 automatically adjusts to the same angle as the workpiece, so that the inner wall of the workpiece fits the roller 4 to achieve a better support effect. The third step is to operate the plate rolling machine to complete the rolling of the workpiece with the assistance of the large-diameter rolling support device. The fourth step is: after taking out the workpiece, the first lifting cylinder 9 descends, and drives the cantilever beam 3 to move downward along the main frame 2 through the chain 7, and the support device returns to the initial position to wait for the next workpiece to be rolled.
