Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, specifically an outlet sliding guide adjustment structure. Background Technology

[0002] Steel rolling is a processing technology that applies pressure to metal billets through a rolling mill to cause plastic deformation, thereby obtaining steel with specific shapes, sizes and properties. This process includes various methods such as hot rolling and cold rolling, and is widely used in fields such as construction, machinery, automobiles, and shipbuilding. It is a key link in the steel industry production process.

[0003] Sliding guides are important devices in steel rolling production. They are installed before and after the mill stand and are used to guide the rolled workpiece to enter and exit the roll pass accurately in a predetermined direction and position. They mainly rely on the relative sliding between the rolled workpiece and the guide to achieve guidance. They have a relatively simple structure, are easy to maintain, and are widely used in various steel rolling production lines.

[0004] When producing rolled products of different specifications, it is necessary to stop the machine to replace the entire set of guide devices, which increases non-production time and affects the continuous operation of the production line. Therefore, an outlet sliding guide adjustment structure is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides an outlet sliding guide adjustment structure, including a guide box; a stepper motor is fixedly connected to the top of the guide box; a rotating rod is fixedly connected to the output end of the stepper motor; connecting rods are rotatably connected to both ends of the rotating rod; a support is rotatably connected to the end of the connecting rod; a wheel frame is fixedly connected to one side of the support; slide rails are slidably connected to both ends of the wheel frame; both ends of the slide rails are fixedly connected to the inner wall of the guide box; a set of guide wheels is rotatably connected to the bottom of the wheel frame; a slider is rotatably connected to the bottom of the guide wheels; a set of sliding grooves is opened on the top of the guide box; a slider is slidably connected to the middle of the sliding grooves. By driving the rotating rod to rotate via the stepper motor and related components, the spacing between multiple sets of guide wheels can be adjusted to adapt to the conveying needs of steel rolling of different diameters. Simultaneously, multiple sets of guide wheels form a continuous guiding channel, applying uniform constraint to the steel rolling, reducing deviation or swaying during conveying, and ensuring that the steel enters the next rolling process in a straight line, improving rolling accuracy and product quality.

[0007] Preferably, a set of connecting pipes is fixed to the side wall of the guide box; the set of connecting pipes is symmetrically arranged; a water pump is installed on one side of the connecting pipe; a nozzle is connected to the end of the connecting pipe; the nozzle is set inside the guide box; a splash plate is installed at the end of the nozzle; a set of drainage grooves is opened at the bottom of the guide box; after the water jet sprayed from the nozzle impacts the splash plate, it spreads out in an umbrella shape along its surface, transforming the concentrated water column into a large-area fan-shaped spray, increasing the coverage of the water column, and cooling multiple surface areas of the rolled steel. After the cooling water absorbs the heat from the surface of the rolled steel, it reduces the temperature of components such as the guide wheel, reduces material softening and wear caused by high temperature, and extends the service life of related components.

[0008] Preferably, a set of electric actuators is fixedly connected to the inner wall of the guide box; the set is symmetrically arranged; a base plate is fixedly connected to the output end of the electric actuator; a wire brush is fixedly connected to the surface of the base plate; a scraper is fixedly connected to one side of the base plate; the scraper is inclined; the wire brush is brought into contact with the surface of the rolled steel by the electric actuator to break the oxide scale through friction, reducing the adhesion between the oxide scale and the rolled steel, and then the inclined scraper is used to scrape off the residue to reduce the surface quality and provide surface conditions for subsequent painting, welding and other processes.

[0009] Preferably, a connecting plate is fixedly connected to the inner side of a set of sliders; a telescopic plate is slidably connected to the surface of the connecting plate; a fixed base plate is slidably connected to the surface of the telescopic plate; the fixed base plate is fixedly connected to the bottom of the guide box; the fixed base plate covers the slide groove; by having the connecting plate slide synchronously with the slider, the telescopic plate can be pulled out from the bottom of the fixed base plate, which can reduce the entry of foreign objects such as oxide scale, iron filings, and cooling water generated on the steel rolling surface into the slide groove, reduce slide groove blockage or slider jamming, and increase the stability and service life of the slider.

[0010] Preferably, multiple spring telescopic rods are fixedly connected to the bottom of the guide box; a tray is fixedly connected to the output end of each spring telescopic rod; the spring telescopic rods and the tray support the rolled steel as it enters the first set of guide wheels, and the spring telescopic rods extend and retract, so that the tray supports the bottom of the rolled steel, calibrates the horizontal posture of the rolled steel, and reduces the rolling steel from getting stuck or the guide wheels from wearing due to height deviation. At the same time, the tray supports the rolled steel to reduce its sag caused by its own weight, so that the rolled steel maintains a straight movement between the two sets of guide wheels.

[0011] Preferably, a plurality of rolling rollers are rotatably connected to the center of the pallet; the rotation direction of the rolling rollers is consistent with the discharge direction. By setting the rotating rolling rollers on the pallet, the conveying resistance of the rolled steel can be reduced, the scratches and abrasions caused by direct contact between the steel surface and the pallet can be reduced, and the service life of the pallet can be extended.

[0012] The advantages of this utility model are:

[0013] 1. The outlet sliding guide adjustment structure of this utility model can adjust the spacing between multiple sets of guide wheels by driving the rotating rod with a stepper motor to rotate the related components, so as to adapt to the conveying needs of steel rolling of different diameters. At the same time, multiple sets of guide wheels form a continuous guiding channel, which applies uniform constraint to the steel rolling, reduces the deviation or shaking of the steel rolling during the conveying process, and allows it to enter the next rolling process in a straight line, thereby improving the rolling accuracy and product quality.

[0014] 2. The outlet sliding guide adjustment structure of this utility model, after the water jet sprayed from the nozzle impacts the splash plate, spreads out in an umbrella shape along its surface, transforming the concentrated water column into a large-area fan-shaped spray, increasing the coverage of the water column, and cooling multiple surface areas of the rolled steel. After the cooling water absorbs the heat from the surface of the rolled steel, it reduces the temperature of components such as the guide wheel, reduces material softening and wear caused by high temperature, and extends the service life of related components.

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, an outlet sliding guide adjustment structure includes a guide box 1; a stepper motor 11 is fixedly connected to the top of the guide box 1; a rotating rod 12 is fixedly connected to the output end of the stepper motor 11; connecting rods 13 are rotatably connected to both ends of the rotating rod 12; a support 14 is rotatably connected to the end of the connecting rod 13; a wheel frame 15 is fixedly connected to one side of the support 14; slide rails 16 are slidably connected to both ends of the wheel frame 15; both ends of the slide rails 16 are fixedly connected to the inner wall of the guide box 1; a set of guide wheels 17 are rotatably connected to the bottom of the wheel frame 15; a slider 18 is rotatably connected to the bottom of the guide wheels 17; a set of sliding grooves 19 are opened on the top of the guide box 1; the slider 18 is slidably connected to the middle of the sliding grooves 19. During operation, the stepper motor 11 is controlled to rotate by a specified angle, so that its output end drives the rotating rod 12 to rotate. Pulling the connecting rod 13 causes its end to engage with the support 14, driving the wheel frame 15 to slide on the slide rail 16. The guide wheel 17 at the bottom of the wheel frame 15 drives the slider 18 to slide in the middle of the slide groove 19 to adjust the spacing between the guide wheels 17. Under the thrust of the rolling mill, the rolled steel is pushed between a set of guide wheels 17. The surface of the guide wheel 17 contacts the rolled steel, causing it to rotate and push the rolled steel into the next set of guide wheels 17 and then leave the guide box 1. By driving the rotating rod 12 to rotate via the stepper motor 11, the spacing between multiple sets of guide wheels 17 can be adjusted to adapt to the conveying needs of rolled steel of different diameters. At the same time, multiple sets of guide wheels 17 form a continuous guiding channel, applying uniform constraint to the rolled steel, reducing the deviation or shaking of the rolled steel during the conveying process, and allowing it to enter the next rolling process in a straight line, improving rolling accuracy and product quality.

[0025] like Figure 2 and Figure 4As shown, a set of connecting pipes 2 are fixed to the side wall of the guide box 1; the set of connecting pipes 2 are symmetrically arranged; a water pump is installed on one side of the connecting pipe 2; a nozzle 21 is connected to the end of the connecting pipe 2; the nozzle 21 is set inside the guide box 1; a splash plate 22 is installed at the end of the nozzle 21; a set of drainage grooves 23 are opened at the bottom of the guide box 1; during operation, the water pump is turned on to inject water into the connecting pipe 2, which is sprayed out through the nozzle 21. After the sprayed water contacts the splash plate 22, it expands the spray range along the surface of the splash plate 22, and finally flows out through the drainage grooves 23. After the water flow sprayed by the nozzle 21 impacts the splash plate 22, it spreads out in an umbrella shape along its surface, transforming the concentrated water column into a large-area fan-shaped spray, increasing the coverage of the water column, and cooling multiple surface areas of the rolled steel. After the cooling water absorbs the heat of the rolled steel surface, it reduces the temperature of components such as the guide wheel 17, reduces material softening and wear caused by high temperature, and extends the service life of related components.

[0026] like Figure 2 and Figure 4 As shown, a set of electric actuators 3 are fixed to the inner wall of the guide box 1; the set is symmetrically arranged; a base plate 31 is fixed to the output end of the electric actuator 3; a wire brush 32 is fixed to the surface of the base plate 31; a scraper 33 is fixed to one side of the base plate 31; the scraper 33 is inclined; during operation, the electric actuator 3 is controlled to extend and retract, so that its output end pushes the base plate 31 to make the wire brush 32 contact the surface of the rolled steel. As the rolled steel moves, the oxide scale is broken, and then scraped off by the scraper 33. The electric actuator 3 makes the wire brush 32 contact the surface of the rolled steel to break the oxide scale by friction, reducing the adhesion between the oxide scale and the rolled steel. Then the inclined scraper 33 is used to scrape off the scale to reduce residue, increase surface quality, and provide surface conditions for subsequent painting, welding and other processes.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a connecting plate 42 is fixedly connected to the inner side of a set of sliders 18; a telescopic plate 41 is slidably connected to the surface of the connecting plate 42; a fixed base plate 4 is slidably connected to the surface of the telescopic plate 41; the fixed base plate 4 is fixedly connected to the bottom of the guide box 1; the fixed base plate 4 covers the slide groove 19; during operation, the slider 18 slides in the middle of the slide groove 19, pulling the connecting plate 42 out from the bottom of the fixed base plate 4, and the connecting plate 42 drives the telescopic plate 41 out from the bottom of the fixed base plate 4 to cover the slide groove 19. By having the connecting plate 42 slide synchronously with the slider 18, and drive the telescopic plate 41 out from the bottom of the fixed base plate 4, it is possible to reduce the entry of foreign objects such as oxide scale, iron filings, and cooling water generated on the surface of the rolled steel into the interior of the slide groove 19, reduce the blockage of the slide groove 19 or the jamming of the slider 18, and increase the stability and service life of the slider 18.

[0028] like Figure 1 , Figure 2 and Figure 5As shown, multiple spring telescopic rods 5 are fixedly connected to the bottom of the guide box 1; a tray 51 is fixedly connected to the output end of the spring telescopic rod 5; during operation, after the rolled steel enters between a set of guide wheels 17, the multiple spring telescopic rods 5 are controlled to extend and retract, holding the rolled steel so that it is level with the next set of guide wheels 17, passing through between a set of guide wheels 17. Through the support of the spring telescopic rods 5 and the tray 51, after the rolled steel enters the first set of guide wheels 17, the spring telescopic rods 5 extend and retract, so that the tray 51 supports the bottom of the rolled steel, calibrates the horizontal posture of the rolled steel, and reduces the jamming of the rolled steel or the wear of the guide wheels 17 caused by the height deviation. At the same time, the tray 51 supports the rolled steel to reduce its sag caused by its own weight, so that the rolled steel maintains a straight movement between the two sets of guide wheels 17.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, a plurality of rolling rollers 6 are rotatably connected to the middle of the pallet 51; the rotation direction of the rolling rollers 6 is the same as the discharge direction. During operation, when the pallet 51 holds the rolled steel, the rolling rollers 6 generate rolling by friction with the rolled steel, reducing the direct contact between the rolled steel and the pallet 51. By setting the rotating rolling rollers 6 on the pallet 51, the conveying resistance of the rolled steel can be reduced, the scratches and abrasions caused by direct contact between its surface and the pallet 51 can be reduced, and the service life of the pallet 51 can be extended.

[0030] Working principle: By controlling the stepper motor 11 to rotate by a specified angle, its output end drives the rotating rod 12 to rotate. The end of the rotating rod 12 pulls the connecting rod 13 so that its end cooperates with the support 14, causing the wheel frame 15 to slide on the slide rail 16. The guide wheel 17 at the bottom of the wheel frame 15 drives the slider 18 to slide in the middle of the slide groove 19 to adjust the spacing between the guide wheels 17. The rolled steel is pushed into a set of guide wheels 17 under the thrust of the rolling mill. The surface of the guide wheel 17 contacts the rolled steel, causing it to rotate and push the rolled steel into the next set of guide wheels 17 and then leave the guide box 1. The water pump is turned on to inject water into the connecting pipe 2, which is sprayed out through the nozzle 21. The sprayed water contacts the splash plate 22 and then spreads along the surface of the splash plate 22. The water flows out through the drain trough 23. The electric actuator 3 is controlled to extend and retract, so that its output end pushes the base plate 31 to make the wire brush 32 contact the surface of the rolled steel. As the rolled steel moves, the oxide scale is broken and then scraped off by the scraper 33. The slider 18 slides in the middle of the chute 19, pulling the connecting plate 42 out from the bottom of the fixed base plate 4. The connecting plate 42 drives the telescopic plate 41 to be pulled out from the bottom of the fixed base plate 4 and cover the chute 19. After the rolled steel enters between a set of guide rollers 17, multiple spring telescopic rods 5 are controlled to extend and retract, holding the rolled steel so that it is level with the next set of guide rollers 17 and passes through between a set of guide rollers 17. When the pallet 51 holds the rolled steel, the rolling roller 6 rolls by friction with the rolled steel, reducing the direct contact between the rolled steel and the pallet 51.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
