Description

1. Technical field

[0002] The utility model belongs to the technical field of plate rolling machines, and particularly relates to a cone-cylinder rolling support device for a plate rolling machine. (II) Background technology

[0004] Plate rolling machines are machine tools used for bending and deforming metal plates, which can roll metal flat plates into round or conical workpieces. Among them, rolling conical workpieces has always been an operational problem in the industry. For thin plates with large diameters, the plate itself has weak rigidity. As the rolling progresses, the plate swings on the plate rolling machine. When the cylinder rolls more than half a circle, the plate collapses, which brings great difficulties and safety risks to the cone rolling operation, and the accuracy is also difficult to control. (III) Contents of the utility model

[0006] In order to make up for the deficiencies of the prior art, the utility model provides a cone-bar rolling support device for a plate rolling machine, which has a simple structure, is easy to operate and can improve the cone-bar workpiece rolling efficiency and precision.

[0007] The utility model is realized through the following technical solutions:

[0008] A cone rolling support device for a plate rolling machine includes a main frame installed on the top of the plate rolling machine frame, and is characterized in that a lifting cylinder is installed in the main frame, a sprocket is installed on the top of the lifting cylinder, a chain is wound around the sprocket, one end of the chain is fixed to the main frame, and the other end of the chain is fixedly connected to the upper right end of the cantilever beam, and a first roller is hinged to the left end of the cantilever beam.

[0009] A second roller is fixedly connected to the middle portion of the cantilever beam.

[0010] A roller is installed at the lower part of the right end of the cantilever beam.

[0011] The side of the main frame is connected to a balancing frame, a stabilizing frame is connected between the balancing frame and the top of the main frame, and a supporting frame is connected between the bottom of the balancing frame and the frame of the plate rolling machine.

[0012] The beneficial effects of the utility model are as follows: when rolling a conical cylinder, the lifting cylinder rises to drive the cantilever beam to move upward, thereby driving the first roller to move upward. When the first roller moves upward, it can automatically adjust to the same angle as the conical workpiece, so that the inner wall of the conical workpiece fits with the first roller to achieve a better supporting effect. The utility model has a reasonable structure, simple installation, and easy use, and effectively improves the rolling efficiency and accuracy of the conical cylinder workpiece.

[0021] With the cone cylinder rolling support device for plate rolling machine of the utility model, the lifting cylinder 3 rises, and the cantilever beam 6 is driven to move upward along the main frame 2 through the chain 5; when the cantilever beam 6 moves upward to the first roller 7 and contacts the inner wall of the conical workpiece, the first roller 7 automatically adjusts to the same angle as the conical workpiece, so that the inner wall of the workpiece fits the first roller 7 to achieve a better support effect; the plate rolling machine is operated to complete the rolling of the workpiece with the assistance of the cone cylinder rolling support device; after the workpiece is taken out, the lifting cylinder 3 descends, and the cantilever beam 6 is driven to move downward along the main frame 2 through the chain 5, and the support device returns to the initial position to wait for the next workpiece to be rolled.
