Therefore, they should not be construed as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a cylinder pressure roller device for rotary forging equipment, comprising a cylinder body 1, a front fixing plate 2, a rear fixing plate 3, and a surrounding plate 4. The surrounding plate 4 is arranged around the cylinder body 1, the front fixing plate 2 is arranged at the front end of the cylinder body 1, and the rear fixing plate 3 is arranged at the rear end of the cylinder body 1. The surrounding plate 4 can be annular in shape and is sleeved on the cylinder body 1.

[0022] The front end of the enclosure 4 abuts against the front fixed plate 2, and the rear end of the enclosure 4 abuts against the rear fixed plate 3. The front fixed plate 2, the rear fixed plate 3 and the enclosure 4 together enclose a sealed cavity 5. The cylinder body 1 is arranged in the sealed cavity 5. The enclosure 4 is provided with a liquid inlet joint 6 and a liquid outlet joint 7. Both the liquid inlet joint 6 and the liquid outlet joint 7 are connected to the sealed cavity 5.

[0023] Based on the above scheme, a sealed cavity 5 is formed by the front fixing plate 2, the rear fixing plate 3 and the surrounding plate 4. The cylinder body 1 is arranged in the sealed cavity 5. The surrounding plate 4 is provided with a liquid inlet joint 6 and a liquid outlet joint 7. The liquid inlet joint 6 and the liquid outlet joint 7 are both connected to the sealed cavity 5. In this way, the coolant can flow into the sealed cavity 5 from the liquid inlet joint 6. The coolant cools the cylinder body 1 in the sealed cavity 5 and takes the heat out from the liquid outlet joint 7, thereby cooling the cylinder body 1 to prevent the cylinder body 1 from being easily damaged when working in a high temperature environment for a long time, thereby ensuring that the cylinder pressure wheel device can work continuously for a long time in the rotary forging room.

[0024] Specifically, an air pipeline can be further provided on the cylinder body 1, which extends from the sealed cavity 5 on the cylinder body 1 and passes through the front fixing plate 2, the rear fixing plate 3 or the enclosure 4, and controls the movement of the cylinder body 1 by supplying gas to the air pipeline.

[0025] In some embodiments, as Figure 1 and Figure 2 As shown, the cylinder pressure wheel device of the rotary forging equipment further includes a connecting member 8, and the front fixing plate 2 is connected to the rear fixing plate 3 via the connecting member 8, so that the front fixing plate 2 and the rear fixing plate 3 clamp the enclosure 4. Specifically, the front fixing plate 2 and the rear fixing plate 3 seal and clamp the enclosure 4 to form a sealed cavity 5.

[0026] In some embodiments, the connector 8 includes a screw 81 and a nut 82. The front fixing plate 2 and the rear fixing plate 3 each have a through hole for the screw 81 to pass through, and the two ends of the screw 81 are threadedly connected to the nut 82. Specifically, the screw 81 passes through the front fixing plate 2 and the rear fixing plate 3, and the front and rear ends of the screw 81 are respectively provided with a nut 82. Tightening the nuts 82 at both ends of the screw 81 causes the two nuts 82 to move toward each other, thereby causing the nuts 82 to apply a force to the front fixing plate 2 and the rear fixing plate 3, so that the front fixing plate 2 and the rear fixing plate 3 are subjected to a force toward the enclosure 4, thereby enabling the front fixing plate 2 and the rear fixing plate 3 to clamp the enclosure 4. There are four screws 81, each located at the four corners of the front fixing plate 2 and the rear fixing plate 3, so that the front fixing plate 2 and the rear fixing plate 3 are subjected to uniform force.

[0027] In some embodiments, the cylinder pressure roller assembly of the rotary swaging equipment further includes a sealing gasket, which is provided between the front end of the enclosure 4 and the front fixing plate 2, and between the rear end of the enclosure 4 and the rear fixing plate 3. The sealing gaskets provide a seal to ensure the tightness of the sealed cavity 5. The shape of the sealing gaskets matches the shape of the front and rear edges of the enclosure 4.

[0028] In some embodiments, as Figure 2 As shown, the front end of the cylinder body 1 is provided with a piston rod 9, which passes through the front fixing plate 2. Specifically, the front fixing plate 2 is provided with a through hole for the piston rod 9 to pass through, and a sealing gasket can be provided between the front end of the cylinder body 1 and the front fixing plate 2 to seal the piston rod 9.

[0029] In some embodiments, as Figure 1 and Figure 2 As shown, the cylinder pressure roller device of the rotary forging equipment further includes a positioning member 10, which is located below the cylinder body 1. One end of the positioning member 10 is connected to the enclosure 4, and the other end of the positioning member 10 is connected to the cylinder body 1. The positioning member 10 is used to position the cylinder body 1 to prevent the cylinder body 1 from moving freely. The positioning member 10 can be fixedly connected to the cylinder body 1.

[0030] In some embodiments, the positioning member 10 is a positioning bolt that passes through the enclosure 4 and is sealed to the enclosure 4. One end of the positioning bolt located in the sealing cavity 5 is threadedly connected to the cylinder body 1. The positioning bolt can be sealed to the enclosure 4 by sealant or welding.

[0031] In some embodiments, the liquid inlet joint 6 and the liquid outlet joint 7 are welded to the enclosure 4. The liquid inlet joint 6 and the liquid outlet joint 7 are metal joints, and the liquid inlet joint 6 and the liquid outlet joint 7 are connected to the coolant circulation device, and the coolant can be water.

[0032] In summary, the embodiment of the utility model provides a cylinder pressure wheel device of a rotary forging equipment, which can allow the coolant to flow into the sealed cavity 5 from the liquid inlet joint 6. The coolant cools the cylinder body 1 in the sealed cavity 5 and takes the heat out from the liquid outlet joint 7, thereby cooling the cylinder body 1, preventing the cylinder body 1 from being easily damaged due to working in a high temperature environment for a long time, and thus ensuring that the cylinder pressure wheel device can work continuously for a long time in the rotary forging room.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
