Description

Technical Field

[0001] The utility model relates to the technical field of tension and straightening rollers, in particular to a durable tension and straightening roller. Background Art

[0002] The straightening machine is an important equipment for the continuous casting machine in a steel plant. Whether the straightening rollers in the straightening machine can work normally directly affects the quality of the finished product.

[0003] Since the temperature of the metal material is relatively high, it is usually necessary to cool the straightening roller in order to extend its service life. After searching, it was found that the straightening rollers in the prior art all adopt a roller center water cooling structure, in which the cooling water enters from the center of one end of the straightening roller and comes out from the center of the other end, flowing in a straight line. However, since the straightening roller is relatively thick, the cooling water is in the center of the roller body, and the cooling effect on the outside of the straightening roller is poor, and the cooling effect is not good. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a durable straightening roller with good cooling effect.

[0005] In order to solve the above-mentioned problem, the utility model proposes a technical solution: a durable straightening roller, comprising a roller body, a circular ring-shaped cavity is provided inside the roller body, a guide plate and a plurality of connecting plates are provided inside the roller body, the guide plate is spiral, a water inlet pipe and a water outlet pipe are rotatably connected at both ends of the roller body, a first annular groove connected to the water inlet pipe and a second annular groove connected to the water outlet pipe are provided at both ends of the roller body, a water outlet connected to the first annular groove and a water inlet connected to the second annular groove are provided on the roller body, and the water inlet pipe and the water outlet pipe both pass through the roller body.

[0006] As an improvement, the guide plate divides the cavity into spiral chambers, and the plurality of connecting plates are located in the chambers.

[0007] As an improvement, both inner and outer sides of the connecting plate and the guide plate are connected to the roller body.

[0008] As an improvement, a keyway is provided on the roller body.

[0009] As an improvement, a first bearing connected to the roller body is provided on the surface of the water inlet pipe, and a second bearing connected to the roller body is provided on the surface of the water outlet pipe.

[0010] As an improvement, sealing rings are provided between the water inlet pipe, the water outlet pipe and the roller body.

[0011] As an improvement, the plurality of connecting plates are all fan-shaped.

[0012] The beneficial effects of the utility model are as follows: the utility model can make the cooling water flow in a spiral shape inside the roller body by arranging a spiral guide plate, and compared with the prior art in which the cooling water flows in a straight line, the contact time between the cooling water and the roller body is longer;

[0013] The connecting plate can quickly transfer the heat from the outside of the roller to the inside, thereby exchanging heat with the cooling water, achieving a good cooling effect. The heat exchange process mainly takes place in the annular cavity, which is closer to the outside of the roller, which is conducive to cooling and prolongs the service life.

[0019] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0020] A durable straightening roller comprises a roller body 5, a keyway 4 is arranged on the roller body 5, and a straightening machine is convenient to drive the roller body 5, a circular ring-shaped cavity 11 is arranged inside the roller body 5, a guide plate 6 and a plurality of connecting plates 7 are arranged inside the cavity 11, the guide plate 6 is spiral-shaped, and the guide plate 6 divides the cavity 11 into spiral chambers, and the plurality of connecting plates 7 are all located in the chambers, and the inner and outer sides of the connecting plates 7 and the guide plates 6 are connected to the roller body 5, and the plurality of connecting plates 7 are all fan-shaped;

[0021] The two ends of the roller body 5 are rotatably connected with a water inlet pipe 1 and a water outlet pipe 3 respectively. The two ends of the roller body 5 are respectively provided with a first annular groove 10 connected to the water inlet pipe 1 and a second annular groove 8 connected to the water outlet pipe 3. The roller body 5 is provided with a water outlet 2 connected to the first annular groove 10 and a water inlet 9 connected to the second annular groove 8. The water inlet pipe 1 and the water outlet pipe 3 both penetrate the roller body 5. The surface of the water inlet pipe 1 is provided with a first bearing connected to the roller body 5, and the surface of the water outlet pipe 3 is provided with a second bearing connected to the roller body 5 for easy rotation. Sealing rings are provided between the water inlet pipe 1, the water outlet pipe 3 and the roller body 5 to ensure sealing.

[0022] Working principle: connect the device to the straightening machine, connect the water pipe to the water inlet pipe 1, and then connect the return pipe to the water outlet pipe 3;

[0023] When working, Figure 4 As shown, the straightening machine drives the roller body 5 to rotate, and inputs cooling water into the water inlet pipe 1 through the water pipe. The cooling water enters the first annular groove 10, and then enters the cavity 11 from the first annular groove 10 through the water outlet 2. The metal material causes the outside of the roller body 5 to heat up, and the connecting plate 7 allows the heat to be quickly transferred from the outside of the roller body 5 to the inside. The cooling water flows in a spiral along the chamber and exchanges heat with the connecting plate 7, the guide plate 6, and the roller body 5. Compared with the existing technology in which the cooling water flows in a straight line, the contact time between the cooling water and the roller body 5 is longer, so as to quickly cool down the roller body 5, and the heat exchange process mainly takes place in the annular cavity 11, which is closer to the outside of the roller body 5, which is conducive to cooling and has a long service life. The heated cooling water enters the water outlet pipe 3 through the water inlet 9 and the second annular groove 8 and is discharged into the return water pipe.
