Description

Technical Field

[0001] This utility model relates to the field of metal strip thickness detection technology, and in particular to an online thickness detection device for metal strip rolling mills. Background Technology

[0002] Metal strip rolling mills are core equipment in the metallurgical industry used to thin and extend metal billets (such as steel, aluminum, copper, etc.) into strips of specific thickness, width and surface quality through multiple rolling passes. After the metal strip is processed by the rolling mill, its thickness usually needs to be tested.

[0003] Existing metal strip thickness detection devices typically use a measuring ruler to detect the thickness of metal strips. However, they cannot continuously detect the thickness of metal strips online during the rolling process. Therefore, we propose an online thickness detection device for metal strip rolling mills.

[0036] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0037] Example:

[0038] like Figures 1-5 As shown, an online thickness detection device for metal strip rolling mills includes:

[0039] The connecting frame 1 has symmetrical through holes on its surface and is bolted to the end of the mill output port;

[0040] Mounting frame 2 is fixedly welded to the inside of connecting frame 1;

[0041] The fixed through groove 3 is fixedly opened at the bottom center of the mounting frame 2;

[0042] The adjustment mechanism 4 is fixedly installed at the bottom of the mounting frame 2;

[0043] The connecting installation mechanism 5 is fixedly mounted at the output end of the connecting adjustment mechanism 4;

[0044] The connection detection mechanism 6 is movably inserted into the inside of the connection installation mechanism 5;

[0045] The connecting limit mechanism 7 is bolted to the front and rear surfaces of the connecting detection mechanism 6.

[0046] The working principle of the above technical solution is as follows:

[0047] During use, the entire assembly can be bolted to the output end of the rolling mill. When the end of the metal strip is conveyed to the inside of the connecting installation mechanism 5, it can push against the end of the connecting detection mechanism 6, allowing the output end of the connecting detection mechanism 6 to move. The thickness of the metal strip is detected based on the movement stroke. Furthermore, the thickness of the metal strip can be continuously detected online as it is conveyed, making the operation convenient and quick.

[0048] In another embodiment, such as Figure 2 As shown, the connecting adjustment mechanism 4 includes fixed mounting end blocks 41 symmetrically located at the bottom of the mounting frame 2. A bidirectional threaded rod 42 is movably connected inside the fixed mounting end block 41. Both ends of the bidirectional threaded rod 42 are fixedly connected to connecting end plates 43. A fixed connecting rod 44 is fixedly connected to one of the connecting end plates 43 on the side away from the bidirectional threaded rod 42. A rotating disk 45 is fixedly connected to the end of the fixed connecting rod 44 away from the connecting end plate 43. Movable mounting blocks 46 are symmetrically connected to the outer surface of the bidirectional threaded rod 42 via threads. A fixed slot 47 is provided on the top of the movable mounting blocks 46. A fixed groove 48 is provided on the side of the movable mounting blocks 46 that is close to each other. A threaded mounting hole is provided on the side of the movable mounting blocks 46 that is close to each other and inside the fixed groove 48.

[0049] The rotating disk 45 is convenient to rotate, which drives the fixed connecting rod 44, the connecting end disk 43 and the bidirectional threaded rod 42 to rotate. This allows the movable mounting block 46 to move on the outer side of the surface of the bidirectional threaded rod 42 and the inner side of the fixed through groove 3, thereby adjusting the position of the connecting mounting mechanism 5 and the connecting detection mechanism 6. This enables the detection of the thickness of metal strips of different sizes, making the operation convenient and quick.

[0050] In another embodiment, such as Figure 2 As shown, the outer top of the movable mounting block 46 slides and fits against the inner side of the fixed through groove 3.

[0051] The top of the movable mounting block 46 can move stably inside the fixed through groove 3, making operation convenient.

[0052] In another embodiment, such as Figure 3 As shown, the connection and installation mechanism 5 includes a connection plug 51 located inside the fixed slot 47. A connection mounting bracket 52 is fixedly connected to the top of the connection plug 51. A connection support leg 53 is fixedly connected to one end of the bottom of the connection mounting bracket 52. A U-shaped through groove 54 is opened on the top of the connection mounting bracket 52. An L-shaped limiting block 55 is symmetrically arranged on the top of the connection mounting bracket 52. A first through hole 56 is symmetrically opened on the top of the L-shaped limiting block 55. The outer surface of the connection support leg 53 is in contact with the inner side of the fixed groove 48.

[0053] The connecting plug 51 can be inserted into the inside of the fixed slot 47, and the connecting leg 53 can be snapped into the inside of the fixed groove 48 and fixed by bolts, so that the connecting mounting bracket 52 can be stably placed on top of the movable mounting block 46 for connection and installation.

[0054] In another embodiment, such as Figure 4 As shown, the connection detection mechanism 6 includes a connection end plate 62 located inside the L-shaped limiting block 55. The surface of the connection end plate 62 is symmetrically provided with second through holes 63. A connection mounting sleeve 61 is fixedly connected to one side of the connection end plate 62. A force spring 64 is fixedly connected to the top of the connection mounting sleeve 61. A connection mounting base 65 is fixedly connected to the bottom of the force spring 64. A connection base rod 66 is fixedly connected to the bottom of the connection mounting base 65. The bottom end of the connection base rod 66 passes through the bottom of the connection mounting sleeve 61 and extends to the outside. A connection base frame 67 is fixedly connected to the bottom of the connection base rod 66. A movable roller 68 is movably connected to the inner side of the connection base frame 67 through a connection shaft. A resistive pull rod displacement sensor 69 is provided on the top of the connection mounting sleeve 61 by bolts. The end detection rod of the resistive pull rod displacement sensor 69 passes through the top of the connection mounting sleeve 61 and extends into the interior of the connection mounting sleeve 61. The end of the detection rod is fixedly connected to the connection mounting base 65.

[0055] The connecting end plate 62 is easily inserted into the inner side of the L-shaped limiting block 55, and under the action of the connecting limiting mechanism 7, it can connect and cooperate with the first through hole 56 and the second through hole 63 for connection and installation. Then, when the metal strip moves inside the connecting support leg 53, the metal strip can push the movable roller 68, so that the movable roller 68 can move upward, driving the connecting base frame 67, the connecting base rod 66 and the connecting mounting base 65 to move, compressing the force spring 64. At this time, it can push the detection rod of the resistive pull rod displacement sensor 69. At this time, the resistive pull rod displacement sensor 69 can detect the thickness of the metal strip according to the movement stroke of the detection rod. When the metal strip is disengaged from the bottom of the movable roller 68, the force spring 64 can push the connecting mounting base 65, the connecting base rod 66, the connecting base frame 67 and the movable roller 68 downward, thereby resetting. The operation is convenient and quick.

[0056] In another embodiment, such as Figure 5 As shown, the connecting limiting mechanism 7 includes positioning seats 71 symmetrically arranged on the front and rear surfaces of the connecting mounting sleeve 61 by bolts. A movable insert rod 72 is movably connected inside the positioning seat 71. A limiting collar 73 is fixedly sleeved on the outer surface of the movable insert rod 72. A connecting top plate 74 is fixedly connected to the top of the movable insert rod 72. A connecting handle 75 is fixedly connected to the top of the connecting top plate 74.

[0057] The connecting handle 75 is moved upwards, which in turn moves the connecting top plate 74, the movable insert rod 72, and the limiting collar 73 upwards. This allows the bottom end of the movable insert rod 72 to disengage from the inside of the first through hole 56 and the second through hole 63, enabling quick adjustment and convenient operation.

[0058] In another embodiment, such as Figure 5 As shown, the outer side of the bottom surface of the movable insertion rod 72 is in contact with the inner side of the first through hole 56 and the second through hole 63.

[0059] The bottom end of the movable insertion rod 72 can be stably inserted into the inner side of the first through hole 56 and the second through hole 63, thereby achieving connection and limiting, and making operation convenient.

[0060] The working principle of this utility model is as follows: First, the entire assembly is connected and installed. Then, the connecting frame 1 is connected to the end of the rolling mill using bolts. Next, as the rolling mill rolls the metal strip and transports it externally, the end of the metal strip moves to the inside of the connecting mounting frame 52, squeezing the movable roller 68. This causes the movable roller 68 to move upwards, driving the connecting base frame 67, connecting base rod 66, and connecting mounting base 65 to move, compressing the force spring 64. This compresses the detection rod of the resistive pull rod displacement sensor 69, allowing the resistive pull rod displacement sensor 69 to detect the thickness of the metal strip based on the movement of the detection rod. When the metal strip detaches from the bottom of the movable roller 68, the force spring 64 pushes the connecting mounting base 65, connecting bottom rod 66, connecting base frame 67, and movable roller 68 downwards to reset them. When the entire connecting detection mechanism 6 needs to be disassembled for inspection and maintenance, the connecting handle 75 is moved upwards, causing the connecting top plate 74, movable insert rod 72, and limiting collar 73 to move upwards, so that the bottom end of the movable insert rod 72 can detach from the inside of the first through hole 56 and the second through hole 63. Then, the entire connecting detection mechanism 6 is moved, so that the connecting end plate 62 moves laterally from the inside of the L-shaped limiting block 55, thereby enabling quick disassembly, inspection, and maintenance. The overall structure is simple and the operation is convenient and quick.

[0061] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
