Description

Technical Field

[0001] This utility model belongs to the technical field of rolling mill preparation equipment, specifically relating to a power-driven rapid separation device. Background Technology

[0002] A slitting mill is used to longitudinally shear moving rolled pieces. It can be installed on the rolling line of a continuous rolling mill, or on slitting mill units, continuous galvanizing mill units, and continuous tin-plating mill units, etc. With the rapid development of continuous rolling mills, slitting mills have been used more and more widely.

[0003] Slitting cuts strips of a certain width into various strips of the required length. During the cutting process, sometimes the driven mechanism does not require power while the unit is running, or it needs to be replaced. In such cases, the unit must be stopped, and the structure between the driven and driving parts must be disassembled. This process is time-consuming, and the entire slitting unit cannot operate during this time, significantly impacting production efficiency and resulting in substantial economic losses for the company.

[0004] Previously, the active device could not be disengaged from the driven device, meaning the power system still needed to operate when no power was required. Furthermore, there were times when the driven device needed to be replaced, such as in mechanisms like double-shear heads, where disengagement was difficult. This inability to disengage significantly impacted production efficiency. Even when disengaged, the level of automation was relatively low, requiring manual disassembly and installation. This not only increased labor costs and reduced production efficiency but also greatly increased safety hazards due to the manual operation of both. Utility Model Content

[0022] To facilitate understanding and implementation of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to embodiments. The embodiments described herein are only for illustration and explanation and are not intended to limit the present utility model.

[0023] Example 1:

[0024] A power quick disengagement device includes a jaw clutch 7, a cylinder support 1, a cylinder 2, and an L-shaped disengagement actuator. The toothless end of the jaw clutch 7 is connected to the motor shaft of the motor 9 of the slitting machine, and the toothed end of the jaw clutch 7 is connected to the input shaft of the gearbox. The cylinder support 1 is fixed to the side wall of the base 8 of the slitting machine. The fixed part of the cylinder 2 is set on the cylinder support 1, and the telescopic part of the cylinder 2 is connected to one end of the disengagement actuator. The other end of the disengagement actuator is connected to the jaw clutch 7. The cylinder 2 drives the toothed end of the jaw clutch 7 to connect or disengage with the input shaft of the gearbox through the disengagement actuator. When the toothed end of the jaw clutch 7 is connected to the input shaft of the gearbox, the motor 9 of the slitting machine transmits power to the input shaft of the gearbox through the jaw clutch 7. When disengagement is required, the cylinder 2 controls the disengagement actuator to drive the toothed end of the jaw clutch 7 to disengage from the input shaft of the gearbox, so that the motor 9 no longer transmits power to the gearbox.

[0025] The separation actuator includes a drive arm 5, a linkage shaft 3, and two swing arms 6. One end of the drive arm 5 is connected to the telescopic part of the cylinder 2, and the other end of the drive arm 5 is fixedly connected to one end of the linkage shaft 3. Two bearings 4 with seats are arranged side by side on the top of the base 8 of the slitting machine. The linkage shaft 3 is connected to the inner ring of each bearing 4 with seats. One end of each of the two swing arms 6 is fixedly connected to the linkage shaft 3. The two swing arms 6 are located on both sides of the jaw clutch 7, and the other end of each swing arm 6 is connected to the jaw clutch 7. The drive arm 5 and the swing arms 6 are L-shaped as a whole. The telescopic part of the cylinder 2 drives the drive arm 5 to rotate around the connection point with the linkage shaft 3. The drive arm 5 drives the linkage shaft 3 to rotate axially. The linkage shaft 3 drives the swing arms 6 to rotate around the connection point with the linkage shaft 3, thereby driving the tooth end of the jaw clutch 7 to connect or separate from the input shaft of the gearbox.

[0026] In one possible implementation, the jaw clutch 7 includes a clutch, a sliding sleeve, and a first guide key. The toothless end of the clutch is connected to the motor shaft of the motor 9 of the slitting machine main unit, and the toothed end of the clutch is connected to the input shaft of the gearbox.

The first keyway is adapted to the first guide key. A first keyway adapted to the first guide key is also provided on the motor shaft of the motor 9 of the slitting machine main unit. The first guide key is disposed in the first keyway on the inner side of the clutch and the first keyway on the motor shaft of the motor 9 of the slitting machine main unit. Lubricating oil is filled between the first guide key and the first keyway, and the clutch can slide along the axial direction of the first guide key. Connecting shafts 10 are provided on both sides of the sliding sleeve, and the connecting shafts 10 are fixed to the swing arm 6 by nuts.

[0027] As one possible implementation method, in order to achieve precise positioning, a meshing slope is provided on the teeth of the clutch, which facilitates the installation or disengagement of the driven end. The meshing slope can accurately position the clutch during engagement and can also reduce the meshing resistance of the teeth of the clutch 7, thereby reducing tooth wear and extending the tooth life of the clutch 7.

[0028] The telescopic part of cylinder 2 is fixedly connected to one end of drive arm 5 by a pin. The other end of drive arm 5 is provided with a second keyway. One end of linkage shaft 3 is also provided with a second keyway. The other end of drive arm 5 and one end of linkage shaft 3 are fixedly connected by a key that matches the second keyway, so as to realize the linkage rotation of drive arm 5 and linkage shaft 3. One end of swing arm 6 is fixedly connected to linkage shaft 3 by a pin, so as to realize the linkage rotation of swing arm 6 and linkage shaft 3.

[0029] As one possible implementation, the toothed end of the clutch is connected to the input shaft of the gearbox in the following manner: the input shaft of the gearbox is provided with external teeth that mesh with the toothed end of the clutch, and the toothed end of the clutch is directly meshed with the toothed end of the input shaft of the gearbox.

[0030] As one possible implementation, the tooth ends of the clutch and the input shaft of the gearbox can also be connected in the following way: a second guide key is provided on the input shaft of the gearbox, a coupling sleeve is provided on the input shaft of the gearbox, a second keyway adapted to the second guide key is provided inside the coupling sleeve, and external teeth that mesh with the tooth ends of the clutch are provided outside the coupling sleeve.
