Abstract
Description
Technical Field
[0001] The utility model relates to the field of hot rolled coil quenching equipment, in particular to a traction and guiding equipment for hot rolled coil quenching. Background Art
[0002] The production and processing of hot-rolled coils requires the roller mechanism to extrude and roll the calcined steel plates. After the roller mechanism rolls the steel plates, the hot-rolled coils need to be quenched. However, under normal circumstances, after the roller mechanism rolls the steel plates, it will continue to move toward the subsequent processing equipment following the traditional conveying mechanism. However, at this time, the hot-rolled coils are thinner and have high plasticity. Therefore, in the subsequent conveying tasks, there will be problems with the coils not being able to be smoothly transported. At the same time, because the hot-rolled coils after extrusion rolling need to be quenched, and when the hot-rolled coils are quenched, the hot-rolled coils themselves need to maintain a certain tension, so that the hot-rolled coils after quenching maintain a certain tension state to meet the use requirements of the hot-rolled coils.
[0003] Therefore, based on the above problems, it is necessary to set up a traction and guiding device for hot-rolled coil quenching, which can ensure that the hot-rolled coil is guided and pulled after rolling, and at the same time ensure that the hot-rolled coil is in a certain tension state, so that the hot-rolled coil has better mechanical properties after quenching. Utility Model Content
[0004] The utility model aims to provide a traction and guiding device for hot-rolled coil quenching, which can ensure that the hot-rolled coil is guided and pulled after rolling, and at the same time ensure that the hot-rolled coil is in a certain tension state, so that the hot-rolled coil has better mechanical properties after quenching.
[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0006] A traction guide device for quenching a hot-rolled coil comprises a guide shell and a guide roller. A driving shaft is arranged on the outer side of the guide shell, and the guide roller is axially rotatably arranged at the open end of the guide shell. When the hot-rolled coil contacts the guide roller, the guide roller drives the hot-rolled piece to approach a cold liquid spraying mechanism, so that the cold liquid spraying mechanism sprays cold liquid on the hot-rolled piece.
[0007] An angular velocity sensor is provided between the guide roller and the rotating shaft of the guide housing, and the angular velocity sensor is connected to a driving shaft connected to the outside of the guide housing, and data feedback is performed between the driving shaft.
[0008] A rotating base is arranged at both ends of the inner side of the guide housing, and the rotating shafts at both ends of the guide roller are mounted on the rotating base, and the guide roller is rotated relative to the rotating base through a bearing.
[0009] A pressure sensor is provided at the position where the rotating base and the guide housing are mounted, and the pressure information applied by the rotating base to the pressure sensor is detected by the pressure sensor.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] When the device is set up, the guide roller is set up to achieve the guiding effect on the hot-rolled coil. After the rolled hot-rolled coil is transmitted out of the rolling mechanism, the guide roller contacts the hot-rolled coil, and the inclined direction of the guide shell is used as the main guiding direction of the hot-rolled coil. At the same time, during the transmission and movement of the hot-rolled coil, the guide roller is driven to rotate, so that the hot-rolled coil is in a certain tension state, ensuring that the hot-rolled coil can be effectively transmitted, avoiding other transmission problems of the hot-rolled coil.

[0016] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0017] A traction guide device for hot-rolled coil quenching includes a guide shell 1 and a guide roller 2. A driving shaft 3 is provided on the outer side of the guide shell 1, and the guide roller 2 is axially rotatably arranged at the open end of the guide shell 1. Here, the guide shell 1 is first connected by the driving shaft 3, and the main body inclination angle of the guide shell 1 can be adjusted by the driving shaft 3. At the same time, the guide roller 2 is arranged at the open end of the guide shell 1, so that after the rolling mechanism rolls the steel plate, it contacts the guide roller 2, and the hot-rolled coil after rolling is guided and pulled by the guide roller 2. When setting here, the guide shell 1 is driven to rotate by the driving shaft 3, so that there is an effective force between the guide roller 2 and the hot-rolled coil. Therefore, the following issues need to be considered here:
[0018] 1. It is necessary to ensure that the force between the hot-rolled coil and the guide roller 2 supports the traction of the hot-rolled coil on the guide roller 2. Because only when the force between the guide roller 2 and the hot-rolled coil is greater than the specified value, can the technical problem of no slipping between the guide roller 2 and the hot-rolled coil be ensured. If the force between the guide roller 2 and the hot-rolled coil is less than a certain value, the friction between the guide roller 2 and the hot-rolled coil will not allow the synchronous displacement between the two, which will cause the hot-rolled coil to slip relative to the guide roller 2, which is not conducive to the guide roller 2 to pull the hot-rolled coil.
[0019] 2. It is necessary to ensure that the force between the hot-rolled coil and the guide roller 2 is less than a certain value. It should be understood that because the temperature of the hot-rolled coil itself is still relatively high after calcination, the plasticity of the hot-rolled coil is still relatively large in this case. Therefore, when quenching the hot-rolled coil, keeping the hot-rolled coil at a certain tension can better achieve the quenching performance of the hot-rolled coil. When the guide roller 2 pulls the hot-rolled coil, if there is no certain force between the two, the hot-rolled coil will not be able to be maintained in a certain tension state. At the same time, if the force applied by the guide roller 2 to the hot-rolled coil is too large, the hot-rolled coil will be over-pulled, so that the hot-rolled coil itself is pulled and stretched under the action of a large pulling force, thereby changing the shape and length of the hot-rolled coil, and cannot meet the subsequent quenching requirements of the hot-rolled coil.
[0020] Therefore, the following structure is set up to solve the above problems:
[0021] An angular velocity sensor 4 is provided between the guide roller 2 and the rotating shaft of the guide housing 1, and the angular velocity sensor 4 is connected to the driving shaft 3 connected to the outside of the guide housing 1, and data feedback is performed between the driving shaft 3. After the angular velocity sensor 4 is provided at the rotating shaft position of the guide roller 2 and the guide housing 1, it is possible to judge whether the guide roller 2 is in a normal rotation state through the angular velocity sensor 4, because when a slip problem occurs between the guide roller 2 and the hot-rolled coil, the hot-rolled coil cannot effectively drive the guide roller 2 to rotate, so that the angular velocity sensor 4 detects abnormal rotation information of the guide roller 2, and then proves the slip problem between the guide roller 2 and the hot-rolled coil. When the above problem occurs, data feedback is performed between the angular velocity sensor 4 and the driving shaft 3, so that the driving shaft 3 drives the guide housing 1 to rotate, thereby increasing the force between the guide roller 2 and the hot-rolled coil, thereby avoiding the slip problem between the guide roller 2 and the hot-rolled coil, so as to ensure that the guide roller 2 can effectively guide the hot-rolled coil.
[0022] A rotating base 5 is provided at both ends of the inner side of the guide housing 1. The rotating shafts at both ends of the guide roller are mounted on the rotating base 5, and the guide roller is rotated relative to the rotating base 5 through bearings. A pressure sensor 6 is provided at the position where the rotating base 5 and the guide housing 1 are mounted, and the pressure information applied to the pressure sensor 6 by the rotating base 5 is detected by the pressure sensor 6. The rotating base 5 is arranged in conjunction with the pressure sensor 6, so that the pressure value of the guide roller 2 on the guide housing 1 can be monitored. Under normal circumstances, the hot-rolled coil will apply a force to the guide roller 2, so that the guide roller 2 rotates following the movement of the hot-rolled coil, and when the driving shaft 3 drives the guide housing 1 to rotate, the relative position between the guide roller 2 and the hot-rolled coil changes, so that the relative force between the guide roller 2 and the hot-rolled coil changes.
[0023] It should be noted here that if only the structure of the pressure sensor 6 is set up without the angular velocity sensor 4, in this case, the force between the hot-rolled coil and the guide roller 2 will be within the specified range, but there will be a relative slip problem between the guide roller 2 and the hot-rolled coil (that is, the guide roller 2 is locked and cannot effectively rotate following the movement of the hot-rolled coil). Therefore, it is necessary to set the angular velocity sensor 4 and the pressure sensor 6 separately here to ensure that the guide roller 2 effectively pulls and guides the hot-rolled coil.
[0024] Therefore, a traction and guiding device for hot-rolled coil quenching can ensure that the hot-rolled coil is guided and pulled after rolling, and at the same time ensure that the hot-rolled coil is in a certain tension state, so that the hot-rolled coil has better mechanical properties after quenching.
