Description
Technical Field
[0001] This utility model relates to the technical field of positioning mechanisms for rapid roll changing, specifically a positioning mechanism that enables rapid roll changing. Background Technology
[0002] In modern industrial production, small rolling mills are widely used in various steel production enterprises as key equipment in metal processing. However, traditional small rolling mills have long faced a series of serious problems in roll positioning and roll changing operations, thus requiring the design of a positioning mechanism that can realize rapid roll changing.
[0003] Traditional small rolling mills cannot adjust the position of the rolls according to the size of the external steel, resulting in poor adaptability to steel of different thicknesses. This increases the product defect rate. Furthermore, during the rolling process, as production continues, a large amount of metal scraps, iron oxide scale, and other impurities adhere to the roll surface. This not only creates additional frictional resistance between the rolls and the steel, accelerating roll wear, shortening their service life, and increasing production costs, but also affects the surface quality of the steel and reduces the product qualification rate. Utility Model Content
[0004] This invention provides a positioning mechanism that enables rapid roll changing, addressing the problem that existing traditional small rolling mills cannot adjust the roll position according to the size of the external steel material, resulting in poor adaptability to steel of different thicknesses, low adaptability, and increased product defect rate. Furthermore, during the rolling process, as production continues, a large amount of metal debris, iron oxide scale, and other impurities continuously adhere to the roll surface, creating additional frictional resistance between the roll and the steel, accelerating roll wear, shortening its service life, increasing production costs, and affecting the surface quality of the steel, thus reducing the product qualification rate.
[0005] This utility model provides the following technical solution: a positioning mechanism for realizing rapid roll changing, including a rolling mill and side frames arranged on both sides of the rolling mill, and further including: a cavity arranged inside the side frame, the bottom of the cavity is fixedly connected to a positioning mechanism, the positioning mechanism includes a fixing block, an adjusting hydraulic rod, a connecting rod, a connecting ring and a lifting hydraulic rod, a side rod arranged on one side of the side frame, the inside of the side rod is fixedly connected to a cleaning mechanism, the cleaning mechanism includes a lead screw, a drive motor, a limit rod and a cleaning brush.
[0006] As a preferred embodiment of this utility model, the positioning mechanism includes a fixed block fixedly connected to the bottom of the cavity, adjustable hydraulic rods are installed on both sides of the fixed block, a connecting rod is fixedly connected to the top of the adjustable hydraulic rod, a connecting ring is fixedly connected to the top of the connecting rod, and a lifting hydraulic rod is fixedly connected to the top of one of the connecting rings.
[0007] As a preferred embodiment of this utility model, the cleaning mechanism includes a lead screw fixedly connected inside a side rod, a drive motor fixedly connected to the top of the lead screw, a limit rod fixedly connected inside one of the side rods, and a cleaning brush provided outside the lead screw.
[0008] As a preferred embodiment of this utility model, a slide rod is rotatably connected to the outside of the lead screw, and an extension hydraulic rod is fixedly connected to one side surface of the slide rod, with the top end of the extension hydraulic rod fixedly connected to the back of the cleaning brush.
[0009] As a preferred embodiment of this utility model, a rotating shaft runs through the interior of the connecting ring, and a slot is provided between the connecting ring and the rotating shaft.
[0010] As a preferred embodiment of this utility model, a sleeve runs through the interior of the hollow groove, and a baffle is fixedly connected to the end of the sleeve.
[0011] As a preferred embodiment of this utility model, a fixing member is fixedly connected to one side of the baffle, and fixing bolts penetrate through both sides of the fixing member.
[0012] As a preferred embodiment of this utility model, a roller is installed on the outside of the rotating shaft, and the rotating shaft passes through the inside of the sleeve.
[0013] Compared with the prior art, this utility model provides a positioning mechanism that enables rapid roll changing, and has the following beneficial effects:
[0014] 1. This positioning mechanism enables rapid roll changing. When the rolls inside the rolling mill need to be adjusted, cavities are created inside the side frames on both sides of the rolling mill. A fixing block is installed at the bottom of each cavity, with a rotating shaft inside the fixing block and a roll installed outside the rotating shaft. The fixing block secures the bottom roll to the bottom of the rolling mill. Adjusting hydraulic rods that can drive the middle roll are installed near both sides of the fixing block. Since the adjusting hydraulic rods are connected to the outside of the rotating shafts at both ends via connecting rings and sleeves, they can drive the middle roll to move and be positioned. The roll above the middle roll moves up and down via the lifting hydraulic rods at the top of the connecting rings on both sides. This achieves adjustable and positioned rolls, avoiding the inability to adjust the position according to the size of the external steel material, which leads to poor adaptability to different thicknesses of steel and increases the product defect rate.
[0015] 2. This positioning mechanism, which enables rapid roll changing, utilizes a cleaning mechanism. Before and after use of the rolling mill, dust is cleaned by installing a lead screw and a limiting rod inside the side rod on the inner edge of the side frame. A drive motor is installed at the top of the lead screw, allowing the sliding rod connecting the lead screw and the limiting rod to move up and down. An extension hydraulic rod is installed on one side of the sliding rod, flexibly extending its length according to the distance between the roll and the cleaning brush as the sliding rod moves up and down. This allows the cleaning brush to adhere to the roll surface for cleaning, effectively removing residual debris from the roll surface, maintaining product quality, and preventing metal debris from adhering to the roll surface. Debris adhering to the roll surface not only creates additional frictional resistance between the roll and the steel, accelerating roll wear, shortening its service life, and increasing production costs, but also affects the surface quality of the steel and reduces the product qualification rate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 - Figure 4 This utility model discloses a positioning mechanism that enables rapid roll changing, including a rolling mill 1 and side frames 2 arranged on both sides of the rolling mill 1. It also includes: a cavity 3 arranged inside the side frame 2, with a positioning mechanism 4 fixedly connected to the bottom of the cavity 3. The positioning mechanism 4 includes a fixing block 401, an adjusting hydraulic rod 402, a connecting rod 403, a connecting ring 404, and a lifting hydraulic rod 405. A side rod 5 is arranged on one side of the side frame 2, with a cleaning mechanism 6 fixedly connected inside the side rod 5. The cleaning mechanism 6 includes a lead screw 601, a drive motor 602, a limit rod 603, and a cleaning brush 604.
[0023] Specifically, the positioning mechanism 4 includes a fixed block 401 fixedly connected to the bottom of the cavity 3. Adjustable hydraulic rods 402 are installed on both sides of the fixed block 401. A connecting rod 403 is fixedly connected to the top of the adjusting hydraulic rod 402. A connecting ring 404 is fixedly connected to the top of the connecting rod 403. A lifting hydraulic rod 405 is fixedly connected to the top of one of the connecting rings 404.
[0024] In this embodiment, cavities 3 are opened inside the side frames 2 on both sides of the rolling mill 1. A fixing block 401 is installed at the bottom of the cavity 3. A rotating shaft 9 is installed inside the fixing block 401, and a rolling mill roll 15 is installed outside the rotating shaft 9. The fixing block 401 fixes the bottom rolling mill roll 15 to the bottom of the rolling mill 1. Then, an adjusting hydraulic rod 402 that can drive the middle rolling mill roll 15 is installed near both sides of the fixing block 401. Since the adjusting hydraulic rod 402 is connected to the outside of the rotating shaft 9 at both ends through the connecting ring 404 and the sleeve 11, it can drive the middle rolling mill roll 15 to move and position. The rolling mill roll 15 above the middle rolling mill roll 15 moves up and down through the two connecting rings 404 and the lifting hydraulic rod 405 at the top of the connecting rings 404.
[0025] Specifically, the positioning mechanism 4 includes a fixed block 401 fixedly connected to the bottom of the cavity 3. Adjustable hydraulic rods 402 are installed on both sides of the fixed block 401. A connecting rod 403 is fixedly connected to the top of the adjusting hydraulic rod 402. A connecting ring 404 is fixedly connected to the top of the connecting rod 403. A lifting hydraulic rod 405 is fixedly connected to the top of one of the connecting rings 404.
[0026] In this embodiment, when dust needs to be cleaned before and after the use of the rolling mill 1, a lead screw 601 and a limiting rod 603 are installed inside the side rod 5 on the inner edge of the side frame 2. A drive motor 602 that can provide power is also installed at the top of the lead screw 601, so that the slide rod 7 connecting the lead screw 601 and the outside of the limiting rod 603 can move up and down. Since an extension hydraulic rod 8 is installed on one side of the slide rod 7, the length can be flexibly extended according to the distance between the roll 15 and the cleaning brush 604 when the slide rod 7 moves up and down, so that the cleaning brush 604 can fit against the surface of the roll 15 for cleaning.
[0027] Specifically, a slide bar 7 is rotatably connected to the outside of the lead screw 601, and an extension hydraulic rod 8 is fixedly connected to one side surface of the slide bar 7. The top end of the extension hydraulic rod 8 is fixedly connected to the back of the cleaning brush 604.
[0028] In this embodiment, the lead screw 601 drives the slide bar 7 to provide horizontal movement power for the cleaning brush 604. The extended hydraulic rod 8 can be flexibly extended and retracted to adjust the height and angle of the cleaning brush 604 to adapt to different rolling conditions. The fixed support of the hydraulic rod can ensure that the cleaning brush 604 fits tightly with the rolling surface, thereby improving the cleaning effect.
[0029] Specifically, a rotating shaft 9 passes through the interior of the connecting ring 404, and a slot 10 is provided between the connecting ring 404 and the rotating shaft 9.
[0030] Specifically, a sleeve 11 runs through the interior of the slot 10, and a baffle 12 is fixedly connected to the end of the sleeve 11.
[0031] In this embodiment, the sleeve 11 is precisely installed through the slot 10, and the baffle 12 can limit the axial displacement of the sleeve 11 or related components to prevent it from falling off or shifting. The support and protection sleeve 11 can provide support and guidance for the components inserted therein, and the baffle 12 can block external impurities from entering the inside of the sleeve and protect the internal structure.
[0032] Specifically, a fastener 13 is fixedly connected to one side of the baffle 12, and a fastener 14 passes through the inside of both sides of the fastener 13.
[0033] Specifically, a roller 15 is mounted on the outside of the rotating shaft 9, and the rotating shaft 9 passes through the inside of the sleeve 11.
[0034] The working principle and usage process of this utility model are as follows: A cavity 3 is opened inside the side frames 2 on both sides of the rolling mill 1. A fixing block 401 is installed at the bottom of the cavity 3. A rotating shaft 9 is installed inside the fixing block 401. A rolling roll 15 is installed outside the rotating shaft 9. The fixing block 401 fixes the bottom rolling roll 15 to the bottom of the rolling mill 1. Then, an adjusting hydraulic rod 402 that can drive the middle rolling roll 15 is installed near both sides of the fixing block 401. Since the adjusting hydraulic rod 402 is connected to the outside of the rotating shaft 9 at both ends through the connecting ring 404 and the sleeve 11, it can drive the middle rolling roll 15 to move and position. The rolling roll 15 above the middle rolling roll 15 moves up and down through the two connecting rings 404 and the lifting hydraulic rod 405 at the top of the connecting ring 404.
[0035] When dust needs to be cleaned before and after the use of the rolling mill 1, a lead screw 601 and a limiting rod 603 are installed inside the side rod 5 on the inner edge of the side frame 2. A drive motor 602 that can provide power is also installed at the top of the lead screw 601, so that the slide rod 7 connecting the lead screw 601 and the outside of the limiting rod 603 can move up and down. Since an extension hydraulic rod 8 is installed on one side of the slide rod 7, the length can be flexibly extended according to the distance between the roll 15 and the cleaning brush 604 when the slide rod 7 moves up and down, so that the cleaning brush 604 can fit against the surface of the roll 15 for cleaning.
[0036] In summary, the positioning mechanism that enables rapid roll changing, through the setting of positioning mechanism 4, realizes the ability to adjust and position the roll 15, avoiding the inability to adjust the position according to the size of the external steel material, which would otherwise lead to an inability to adapt to steel materials of different thicknesses, resulting in low adaptability and an increased product defect rate.
[0037] By setting up the cleaning mechanism 6, residual debris on the surface of the roll 15 is cleaned, maintaining product quality and preventing metal debris from adhering to the surface of the roll 15. This not only creates additional frictional resistance between the roll 15 and the steel, exacerbating the wear of the roll 15, shortening its service life, and increasing production costs, but also affects the surface quality of the steel and reduces the product qualification rate.
