Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate hot rolling, and particularly relates to a side guiding device for hot rolled strip steel of light aluminum plates. Background Art

[0002] In an aluminum plate hot rolling mill, after rough rolling and finish rolling, the strip steel is thin and prone to camber. When the rolled strip runs on the roller table, it is likely to deviate. A side guiding device is provided at the outlet of the mill to push the strip to the center position of the roller table and ensure that the position of the strip does not deviate before entering the outlet shearing machine.

[0003] Currently, common aluminum plate side guiding devices generally consist of a hydraulic cylinder and a side pushing frame body. The side pushing frame body is assembled at the output end of the hydraulic cylinder, and the movement of the side pushing frame body towards the transport roller table is realized by the telescopic movement of the hydraulic cylinder. However, due to the self-weight of the side pushing frame body, the piston rod of the hydraulic cylinder bears a large bending moment. Over time, the piston rod of the hydraulic cylinder bends and deforms, and is prone to jamming, affecting the movement accuracy of the side pushing frame body. Therefore, the hydraulic cylinder needs to be replaced irregularly, and the operation is rather cumbersome. Summary of the Utility Model

[0004] The problem solved by the utility model is: how to improve the movement accuracy of the side pushing frame body.

[0005] To solve the above problems, the utility model provides a side guiding device for hot rolled strip steel of light aluminum plates, which is used to be installed on both sides of the transport roller table and includes a frame body, a hydraulic cylinder, a guiding rod, and a side pushing structure. The hydraulic cylinder is installed on the frame body and is drivingly connected to the side pushing structure. There are two guiding rods, and the two guiding rods are symmetric about the hydraulic cylinder. Each guiding rod is slidably connected to the frame body along the driving direction of the hydraulic cylinder and is connected to the side pushing structure.

[0006] Optionally, two cylindrical sleeves are arranged on the frame body, and the two guiding rods correspondingly pass through the two cylindrical sleeves and can slide relative to the two cylindrical sleeves.

[0007] Optionally, the side guiding device for hot rolled strip steel of light aluminum plates further includes two synchronous gears. Tooth structures are arranged on both guiding rods, and the tooth structures are distributed along the axial direction of the guiding rods. The two synchronous gears are respectively meshed with the tooth structures on the two guiding rods and are synchronously rotated and assembled on the frame body through a rotating shaft.

[0008] Optionally, a groove is arranged on the frame body, and the groove is located below the guiding rod. The two synchronous gears are assembled in the groove.

[0009] Optionally, the groove is located below the cylindrical sleeve, and a notch is provided on the cylindrical sleeve, and the synchronous gear meshes with the corresponding tooth structure through the notch.

[0010] Optionally, a backing plate is provided on the side pushing structure, and the backing plate is located at one end of the side pushing structure facing the conveying roller path.

[0011] Optionally, the hydraulic cylinder is provided with a displacement sensor, and the displacement sensor is used for communication connection with the control center.

[0014] Optionally, the frame body is arranged as a frame structure made by welding a plurality of steel plates.

[0015] Compared with the prior art, in the side guiding device for hot-rolled strip of light aluminum plate of the present utility model, the hydraulic cylinder is installed on the frame body and is drivingly connected with the side pushing structure. The hydraulic cylinder realizes the movement of the side pushing structure towards the conveying roller path, so that the side pushing structure can limit the movement track of the aluminum plate on the conveying roller path, thereby ensuring that the aluminum plate moves along the middle line of the conveying roller path.

[0021] In the attached drawings, the Z-axis represents the vertical position, and the positive direction of the Z-axis (i.e., the direction pointed by the arrow of the Z-axis) represents the upper side, and the negative direction of the Z-axis (i.e., the direction opposite to the positive direction of the Z-axis) represents the lower side; the X-axis in the attached drawings represents the horizontal position, and the positive direction of the X-axis (i.e., the direction pointed by the arrow of the X-axis) represents the right side, and the negative direction of the X-axis (i.e., the direction opposite to the positive direction of the X-axis) represents the left side; the Y-axis in the attached drawings represents the front-back position, and the positive direction of the Y-axis (i.e., the direction pointed by the arrow of the Y-axis) represents the front side, and the negative direction of the Y-axis (i.e., the direction opposite to the positive direction of the Y-axis) represents the back side. At the same time, it should be noted that the meanings represented by the foregoing Z-axis, Y-axis and X-axis are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0022] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned attached drawings of the present invention are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0023] Combined with Figure 1 As shown, the present invention provides a side guide device for hot-rolled strip of light aluminum plate, which is used to be installed on both sides of a conveying roller table, and includes a frame 1, a hydraulic cylinder 2, a guide rod 3 and a side pushing structure 4. The hydraulic cylinder 2 is installed on the frame 1 and is drivingly connected to the side pushing structure 4. There are two guide rods 3, and the two guide rods 3 are symmetrical about the hydraulic cylinder 2. Each guide rod 3 is slidably connected to the frame 1 along the driving direction of the hydraulic cylinder 2 and is connected to the side pushing structure 4.

[0024] Specifically, the conveying direction of the transport roller table can be the positive direction of the Y-axis. Two side guiding devices for hot-rolled light aluminum plates are fixed on both sides in the width direction of the transport roller table. The side guiding device for hot-rolled light aluminum plates includes a frame body 1, a hydraulic cylinder 2, a guiding rod 3, and a side pushing structure 4. The frame body 1 can be a box structure made by welding. The hydraulic cylinder 2 is assembled at the upper end of the frame body 1. The piston rod of the hydraulic cylinder 2 is connected to the side pushing structure 4 through a pin shaft. The piston rod of the hydraulic cylinder 2 faces the transport roller table, and guiding rods 3 are respectively distributed on the front and rear sides of the hydraulic cylinder 2. The two guiding rods 3 are symmetric about the hydraulic cylinder 2 and are slidably arranged at the upper end of the frame body 1. And the ends of the two guiding rods 3 facing the transport roller table are both welded to the side pushing structure 4. The two guiding rods 3 can support the side pushing structure 4 to reduce the bending moment load on the hydraulic cylinder 2 by the side pushing structure 4. When guiding the aluminum plate, the hydraulic cylinder 2 drives the side pushing structure 4 to move towards the transport roller table, and the two guiding rods 3 guide the movement of the side pushing structure 4. When the side pushing structure 4 moves to the required position, a moving channel for the aluminum plate is formed between the two side pushing structures 4 to ensure that the aluminum plate can move along the center line of the transport roller table.

[0025] Therefore, in this embodiment, by installing the hydraulic cylinder 2 on the frame body 1 and drivingly connecting it to the side pushing structure 4, the hydraulic cylinder 2 realizes the movement of the side pushing structure 4 towards the transport roller table, so that the side pushing structure 4 can limit the movement track of the aluminum plate on the transport roller table, thereby ensuring that the aluminum plate moves along the center line of the transport roller table. Then, by using the two guiding rods 3 being symmetric about the hydraulic cylinder 2 and respectively slidably connected to the frame body 1, and both of the two guiding rods 3 being connected to the side pushing structure 4, the two guiding rods 3 can support the side pushing structure 4, thereby reducing the bending moment load on the hydraulic cylinder 2 from the side pushing structure 4 to ensure the use stability of the hydraulic cylinder 2, and thus ensuring the movement accuracy of the side pushing structure 4.

[0026] Optionally, as shown in Figure 1 two cylindrical sleeves 11 are arranged on the frame body 1, and the two guiding rods 3 correspondingly pass through the two cylindrical sleeves 11 and can slide relative to the two cylindrical sleeves 11.

[0027] Specifically, the two cylindrical sleeves 11 are distributed at the upper end of the frame body 1 and are installed on the frame body 1 along the front and rear directions of the frame body 1. The two guiding rods 3 respectively pass through the two cylindrical sleeves 11 and slide inside the cylindrical sleeves 11.

[0028] In this way, by arranging two cylindrical sleeves 11 on the frame body 1, the two guiding rods 3 correspondingly pass through the two cylindrical sleeves 11 and can slide relative to the two cylindrical sleeves 11. The two cylindrical sleeves 11 increase the contact area between the frame body 1 and the two guiding rods 3 and can radially limit the two guiding rods 3, so that the two guiding rods 3 only move along the axial direction of the two cylindrical sleeves 11 to improve the movement accuracy of the two guiding rods 3.

[0029] Optionally, in combination with Figure 1 and Figure 2 As shown, the side guide device for hot-rolled strip of light aluminum plate further includes two synchronous gears 5. Tooth structures are provided on both guiding rods 3, and the tooth structures are distributed along the axial direction of the guiding rods 3. The two synchronous gears 5 are respectively meshed with the tooth structures on the two guiding rods 3, and are rotationally assembled on the frame body 1 synchronously through a rotating shaft.

[0030] Specifically, taking the lower end of the guiding rod 3 as an example, a tooth structure is provided at the lower end of the guiding rod 3, and the tooth structure is arranged along the axial direction of the guiding rod 3 to form a rack at the lower end of the guiding rod 3. The rotating shaft is assembled on the frame body 1 through a bearing seat and is key-connected to the synchronous gear 5. The two synchronous gears 5 are respectively meshed with the tooth structures on the two guiding rods 3 correspondingly. When one guiding rod 3 moves axially, it can drive the other guiding rod 3 to move synchronously through the two synchronous gears 5 and the rotating shaft.

[0031] In this way, by providing tooth structures on both guiding rods 3, the tooth structures are distributed along the axial direction of the guiding rods 3, racks are formed on the guiding rods 3, and the two synchronous gears 5 are respectively meshed with the tooth structures on the two guiding rods 3. The two synchronous gears 5 are rotationally assembled on the frame body 1 synchronously through a rotating shaft, so that a gear-rack structure is formed between the synchronous gears 5 and the guiding rods 3, ensuring that the two guiding rods 3 can move synchronously, thereby avoiding uneven loading of the side pushing structure 4 and improving the moving accuracy of the side pushing structure 4.

[0032] Optionally, in combination with Figure 1 As shown, a groove 6 is provided on the frame body 1. The groove 6 is located below the guiding rod 3, and the two synchronous gears 5 are assembled in the groove 6.

[0033] Specifically, the extending direction of the groove 6 is the transportation direction of the transportation roller table. The groove 6 is located below both guiding rods 3. Bearing seats are respectively assembled at the front and rear ends of the groove 6. The rotating shaft is respectively connected to the two bearing seats. The two synchronous gears 5 are respectively assembled on the rotating shaft and are respectively meshed with the tooth structures on the two guiding rods 3 correspondingly.

[0034] In this way, by providing the groove 6 located below the guiding rod 3 on the frame body 1, the two synchronous gears 5 are assembled in the groove 6 through the rotating shaft. The groove 6 can provide an installation space for the rotating shaft and the two synchronous gears 5, so that the rotating shaft and the two synchronous gears 5 can be "embedded" on the frame body 1, thereby reducing the occupation of the external space of the frame body 1 by the rotating shaft and the two synchronous gears 5 and making the overall side guide device for hot-rolled strip of light aluminum plate compact.

[0035] Optionally, in combination with Figure 1 and Figure 2 As shown, the groove 6 is located below the cylindrical sleeve 11. A notch is provided on the cylindrical sleeve 11, and the synchronous gear 5 meshes with the corresponding tooth structure through the notch.

[0036] Specifically, the groove 6 is located below the cylindrical sleeve 11. A notch is provided on the side wall of the cylindrical sleeve 11 close to the notch of the groove 6. The notch can at least accommodate part of the structure of the synchronizing gear 5 so that the synchronizing gear 5 meshes with the corresponding tooth structure from the notch.

[0037] In this way, since the groove 6 is located below the cylindrical sleeve 11, a notch is provided on the cylindrical sleeve 11, and the synchronizing gear 5 meshes with the corresponding tooth structure from the notch, the cylindrical sleeve 11 can cover the tooth structure of the synchronizing gear 5 to prevent the tooth structure of the synchronizing gear 5 from being damaged, thereby protecting the tooth structure of the synchronizing gear 5.

[0038] Optionally, in combination with Figure 1 and Figure 2 as shown, a backing plate 41 is provided on the side pushing structure 4. The backing plate 41 is located at one end of the side pushing structure 4 facing the conveying roller path.

[0039] Specifically, the backing plate 41 is located at one end of the side pushing structure 4 facing the conveying roller path, that is, the left end of the side pushing structure 4. The backing plate 41 extends along the conveying direction of the conveying roller path, and the backing plate 41 guides the aluminum plate. In this way, since the backing plate 41 is located at one end of the side pushing structure 4 facing the conveying roller path and is used to contact the aluminum plate, the backing plate 41 can reduce the wear or collision between the aluminum plate and the side pushing structure 4. And through the setting of the backing plate 41, the shape requirement for the side pushing structure 4 can be reduced, so as to simplify the structure of the side pushing structure 4.

[0040] Optionally, the hydraulic cylinder 2 is equipped with a displacement sensor, and the displacement sensor is used for communication connection with the control center.

[0041] Specifically, the hydraulic cylinder 2 is a hydraulic cylinder 2 with a built-in displacement sensor. The displacement sensor can directly observe the telescopic displacement amount of the piston rod of the hydraulic cylinder 2, so that the control center can adjust the telescopic displacement of the piston rod of the hydraulic cylinder 2 according to the feedback of the displacement sensor, so as to better adapt to the side pushing and guiding effects of different aluminum plates (the widths of the aluminum plates on the conveying roller path are different).

[0042] In this way, since the hydraulic cylinder 2 is equipped with a displacement sensor, the displacement sensor is used for communication connection with the control center, and the displacement sensor can directly feedback the telescopic displacement of the piston rod of the hydraulic cylinder 2, so as to adjust the telescopic amount of the piston rod of the hydraulic cylinder 2, thereby facilitating the remote control of the hydraulic cylinder 2 to adapt to the side pushing and guiding effects of different aluminum plates.

[0043] Optionally, in combination with Figure 1 as shown, the side pushing structure 4 extends along the conveying direction of the conveying roller path. Guide surface structures 42 are respectively provided at both ends of the side pushing structure 4, and the included angle between the guide surface structures 42 and the conveying direction is an acute angle.

[0044] Specifically, the two guide surface structures 42 are distributed at the front and rear ends of the side push structure 4 along the Y axis, and are located at the side end of the side push structure 4 facing the transport roller, that is, the left end of the side push structure 4. The two guide surface structures 42 are inclined surfaces. For the guide surface structure 42 located in the negative direction of the Y axis, the front end of the guide surface structure 42 is located at the pad 41, and the rear end is inclined away from the transport roller along the direction away from the transport direction, so that the angle between the guide surface structure 42 and the transport direction is acute. For the guide surface structure 42 located in the positive direction of the Y axis, the rear end of the guide surface structure 42 is located at the pad 41, and the front end is inclined away from the transport roller along the direction of transport, so that the angle between the guide surface structure 42 and the transport direction is acute. When the aluminum plate guide surface structure 42 contacts, the guide surface structure 42 guides the aluminum plate to slide, so that the aluminum plate moves toward the transport roller, so that the aluminum plate moves between the two side push plates 4.

[0045] In this way, the side push structure 4 extends along the conveying direction of the transport roller, and guide surface structures 42 are respectively provided at both ends of the side push structure 4. The angle between the guide surface structure 42 and the conveying direction is an acute angle. The guide surface structure 42 can guide the aluminum plate to between the two side push plates 4, thereby avoiding interference between the aluminum plate and the side push plate 4 to ensure the reliability of the side push plate 4.

[0046] Optionally, combined Figure 1 As shown, the thrust structure 4 is configured as a hollow structure.

[0047] Specifically, the thrust structure 4 as a whole can be a rectangular box structure made of six steel plates welded together. The length of the rectangular box structure is much greater than its width, and the pad 41 is installed on the left end of the rectangular box structure by bolts.

[0048] In this way, by setting the side thrust structure 4 as a hollow structure, the weight of the side thrust structure 4 can be reduced, the side thrust structure 4 can be manufactured lightly, and the longitudinal load received by the hydraulic cylinder 2 can be reduced.

[0049] Optionally, combined Figure 1 As shown, the frame 1 is configured as a frame structure made by welding a plurality of steel plates.

[0050] Specifically, the main part of the frame 1 is a rectangular box structure made of six welded steel plates. At the top of the rectangular box structure, multiple parallel steel plates are welded to form the groove 6, the mounting groove of the cylindrical sleeve 11 and the mounting groove of the hydraulic cylinder 2 mentioned above.

[0051] In this way, by configuring the frame 1 as a frame structure formed by welding a plurality of steel plates, the structure of the frame 1 is simplified, the manufacturing cost of the frame 1 is reduced, and the weight of the frame 1 can be reduced, thereby achieving lightweight manufacturing of the frame 1.

[0052] Although the present disclosure is disclosed as above, the scope of protection of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the scope of protection of the present utility model.
