Description

Technical Field

[0001] This invention relates to the field of hot-rolled coil leveling machine technology, specifically a continuous leveling processing unit for hot-rolled coils. Background Technology

[0002] The hot-rolled coil leveling unit improves the flatness of the steel plate and eliminates the yield plate to enhance its deep-drawing performance by applying a certain pressure to the strip during rolling. Ultimately, this significantly improves the product's appearance, processing performance, and transportation suitability.

[0003] For example, Chinese Patent (Announcement No.: CN111498547B) discloses a flattening and straightening device for steel coil winding, including a support box, a flattening mechanism, a bending sensing mechanism, a top pulling mechanism, a leveling mechanism, a coating mechanism, a winding mechanism, and two clamping mechanisms. The support box, winding mechanism, and coating mechanism are all fixedly installed on the ground. The flattening mechanism, bending sensing mechanism, top pulling mechanism, leveling mechanism, edge cutting mechanism, and two clamping mechanisms are all fixedly installed on the flattening mechanism. This flattening and straightening device for steel coil winding performs coating and winding of the steel coil simultaneously. The flattening mechanism flattens the surface of the steel coil, thus avoiding unevenness on the surface of the coated steel coil. However, when encountering small wrinkles, the two clamping mechanisms press the steel coil, and the top pulling mechanism flattens the wrinkles. The edge cutting mechanism can cut off excess waste on both sides of the steel coil.

[0004] However, the smoothing continuity of this device is not high enough. When using this device, it can only smooth one steel coil at a time. It is necessary to wait for the single steel coil to be smoothed before a new steel coil can be connected. Therefore, the continuous use is not high enough. So, a continuous smoothing unit for hot-rolled coils is proposed to solve the above problems. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 3 This embodiment of a hot-rolled coil continuous leveling unit includes an unwinding assembly 1 and a protective shell 2. The inner side of the protective shell 2 is provided with a switching mechanism 3 that can connect two steel coils simultaneously. Three primary guide blocks 4 are fixed between the front and rear side walls of the inner cavity of the protective shell 2. The inner bottom wall of the protective shell 2 is provided with multiple rough leveling mechanisms 5 located to the right of the primary guide blocks 4 and capable of performing initial leveling on the hot-rolled coil. Two secondary guide blocks 6 are fixed between the front and rear side walls of the inner cavity of the protective shell 2 and located to the right of the rough leveling mechanisms 5. The right side of the protective shell 2 is provided with a hot pressing mechanism 7 capable of further leveling the hot-rolled coil.

[0031] In addition, the unwinding assembly 1 includes two support frames 101, which are fixed by stacking. Each support frame 101 has a rotating rod 102 rotatably connected to its inner side, which passes through the side wall of the support frame 101. The outer surface of the rotating rod 102 is rotatably connected to a connecting ring 103 via a bearing. The connecting ring 103 can provide stable support force for the rotating rod 102. Each support frame 101 has a barrier cover 104 fixed to its left and right sides by bolts. The barrier cover 104 can limit the rotation of the rotating rod 102, thereby ensuring the stable rotation of the unwinding roller 105. Each barrier cover 104 has a pull ring 106 fixed to the side away from the support frame 101. The pull ring 106 can facilitate the user to pull the rotating rod 102. The outer surface of each rotating rod 102 is fitted with an unwinding roller 105.

[0032] It should be further explained that the protective shell 2 is open on both the left and right sides. The open protective shell 2 can ensure that the hot rolled coil can smoothly enter and leave the protective shell 2. Each support frame 101 has a mounting hole through the side wall of the support frame 101 on both the left and right sides. The side wall of the mounting hole can provide support for the connecting ring 103. Multiple connecting keys are fixed on the outer surface of the rotating rod 102 and multiple keyways are opened on the inner side wall of the unwinding roller 105. The multiple connecting keys extend into the multiple keyways respectively. Sliding grooves communicating with the mounting holes are also opened on the left and right side walls of the support frame 101. A sliding block extending into the sliding groove is fixed on the outer surface of each connecting ring 103.

[0033] In addition, the switching mechanism 3 includes an electric actuator 301 fixed to and penetrating the top wall of the protective shell 2. The electric actuator 301 provides power for the up-and-down movement of the stabilizing base 302. The switching mechanism 3 also includes two stabilizing bases 302. Each stabilizing base 302 has a drive shaft 304 rotatably connected to its inner side via bearings. The drive shaft 304 ensures the stable rotation of the drive transmission wheel 305 and also transmits power to the drive transmission wheel 305. The inner front wall of the protective shell 2 is rotatably connected to two supporting shafts 303 via bearings. The outer surface of each drive shaft 304 is fixed with... The active transmission wheel 305 and the passive transmission wheel 306 are fixed on the outer surface of each supporting shaft 303. The inner rear wall of the protective shell 2 is provided with a transmission component 307, which can realize power transmission. The inner rear wall of the protective shell 2 is provided with a connecting seat 308 located on the left side of the stable seat 302. The front of the protective shell 2 is provided with a displacement component 309, which can convert the power of the electric push rod 301 to cause the connecting seat 308 to move in the opposite direction to the stable seat 302. The inner bottom wall of the protective shell 2 is provided with a telescopic rod 310, which can provide assistance to the connecting seat 308, thereby improving the stability of the connecting seat 308.

[0034] Furthermore, the transmission assembly 307 includes a drive rod 3071, and a drive gear 3072 is fixed on the outer surface of the drive rod 3071. The drive gear 3072 can only mesh with one driven gear 3073. When the drive gear 3072 meshes with one driven gear 3073, the other driven gear 3073 cannot transmit power because the distance is too far. A driven gear 3073 that meshes with the drive gear 3072 is fixed on the outer surface of each drive shaft 304 and on the rear side of the stabilizing seat 302. A drive motor is fixed on the inner rear wall of the protective shell 2. The drive motor can provide power for the rotation of the drive rod 3071. The output shaft of the drive motor is fixed to the drive rod 3071.

[0035] It is known that sliding wheels are fixed on the inner side of both connecting seats 308. The fixing of sliding wheels and support wheels can improve the overall stability. Two support wheels are fixed between the front and rear side walls of the inner cavity of the protective shell 2. Four connecting rods are fixed on the opposite side of the two connecting seats 308 and the opposite side of the two stabilizing seats 302. The eight connecting rods are in groups of four. Four connecting rods are used to provide connecting force for the two connecting seats 308, and the other four are used to provide connecting force for the two stabilizing seats 302.

[0036] It should be further explained that the displacement assembly 309 includes two connecting bars 3091, four connecting rods between two connecting seats 308, wherein the connecting rod on the right front is fixed to the connecting bar 3091, and four connecting rods between two stabilizing seats 302, wherein the connecting rod on the left front is fixed to the connecting bar 3091. Both connecting bars 3091 extend into the protective shell 2 and are fixed to the two connecting rods respectively. On the opposite side of the two connecting bars 3091 and outside the protective shell 2, a rack 3092 is fixed. Through the transmission relationship of multiple transmission gears 3094, the two racks 3092 are driven to move in opposite directions. The protective shell 2 is rotatably connected to multiple drive shafts 3093 via bearings on its front side. Each drive shaft 3093 has a drive gear 3094 fixed on its outer surface that meshes with two racks 3092. The front side of the protective shell 2 is fixed with two limiting strips 3095 located on opposite sides of the two connecting strips 3091. T-slots 3096 are provided on opposite sides of the two limiting strips 3095. T-blocks 3097 extending into the T-slots 3096 are fixed on opposite sides of the two connecting strips 3091. The cooperation between the T-slots 3096 and the T-blocks 3097 can improve the stability of the racks 3092.

[0037] In this embodiment, when the active transmission wheel 305 provides power for the hot-rolled coil conveying, the corresponding sliding wheel and support wheel will separate from each other to ensure that the hot-rolled coil can move stably. Meanwhile, the power transmission on the other side is interrupted, and the sliding wheel and support wheel on the other side move closer to each other to clamp the hot-rolled coil.

[0038] Please refer to it again. Figure 1 , Figure 4 , Figure 5 and Figure 6 To further improve the flatness, each roughing mechanism 5 in this embodiment consists of a pressing assembly 501 and an adjusting assembly 502. Each pressing assembly 501 includes two sealing shells 5011 fixed to the inner bottom wall of the protective shell 2. A support spring 5012 is fixed to the bottom of each sealing shell 5011, and the support spring 5012 provides auxiliary support for the piston 5013. A piston 5013 is fixed to the other side of each support spring 5012, which fits against the inner wall of the sealing shell 5011. The piston 5013 and the sealing shell 5011 have a good seal. Each piston 5013 has a movable rod 5014 fixed to its top, extending out of the sealing shell 5011. Each movable rod 5014 has two slides 5015 above it, and two primary hydraulic rods 5016 are arranged between the two slides 5015. Each slide 5015 has a through support shaft 5017 rotatably connected to its inner side. Each slide 5015 has a rotating motor fixed to its rear side, and a bracket is fixed to the outer surface of the rotating motor. The rotating motor is fixed to the slide 5015 through the bracket, and the output shaft of each rotating motor is fixed to the support shaft 5017.

[0039] Furthermore, each of the adjustment components 502 includes a bidirectional hydraulic pump 5021 fixed to the bottom of the protective shell 2. The bidirectional hydraulic pump 5021 can cause the hydraulic oil to move, thereby providing power for the movement of the piston 5013. Both sides of the bidirectional hydraulic pump 5021 are fixedly connected to a liquid passage pipe 5022 that penetrates the bottom wall of the protective shell 2. The liquid passage pipe 5022 can provide power for the flow of liquid. The other end of each liquid passage pipe 5022 is fixedly connected to the sealing shell 5011.

[0040] In addition, the hot pressing mechanism 7 includes a connecting frame 701. Multiple secondary hydraulic rods 704 are fixed to the top of the connecting frame 701. The secondary hydraulic rods 704 can control the distance between the top plate 705 and the connecting frame 701. The top plate 705 is fixed to the top of the multiple secondary hydraulic rods 704. Multiple support seats 702 are fixed on the opposite side of the connecting frame 701 and the top plate 705. Each support seat 702 is provided with a heat-conducting component 703 on its inner side.

[0041] Understandably, each heat-conducting component 703 includes a protective sleeve 7031, and a filling rod 7032 is fixed inside each protective sleeve 7031. The outer surface of the filling rod 7032 is provided with a spiral groove 7033. Each protective sleeve 7031 has an end cap 7034 fixedly connected to its front and rear sides. The front and rear ends of the end cap 7034 are rotatably connected to a heating tube through bearings. The bearing between the end cap 7034 and the heating tube is a sealed bearing. The heating tube is fixedly connected to a heating device, which is used to stably provide heating liquid. A drive gear 7035 is fixed to the outer surface of the rear end cap 7034. An oil pump motor is fixed to the rear side of the connecting frame 701 and the top plate 705. A rotating gear is fixed to the outer surface of the output shaft of each oil pump motor. Multiple rotating gears mesh with multiple drive gears 7035 respectively.

[0042] In this embodiment, oil pipes are fixedly connected to the outer surfaces of the primary hydraulic rod 5016 and the secondary hydraulic rod 704, and oil pumps are fixedly connected to the other ends of the oil pipes. The oil pumps provide power for the extension and retraction of the primary hydraulic rod 5016 and the secondary hydraulic rod 704.

[0043] Understandably, the back of the protective shell 2 is equipped with a control console, which controls the switching mechanism 3, the roughing mechanism 5, and the hot pressing mechanism 7.

[0044] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0045] The working principle of the above embodiments is as follows:

[0046] (1) When in use, first connect both steel coils to the switching mechanism 3, then start the electric push rod 301. The electric push rod 301 causes the stabilizing seat 302 to move, and at the same time, the power will be transmitted to the displacement component 309. Due to the action of multiple transmission gears 3094, the two racks 3092 will move in opposite directions. When one active transmission wheel 305 approaches the passive transmission wheel 306, the other active transmission wheel 305 will move away from the passive transmission wheel 306 and interrupt the power transmission. At the same time, one of the two hot-rolled coils will be clamped and the other will be released. The released coil will be moved towards the roughing and leveling mechanism 5 by the action of the active transmission wheel 305.

[0047] (2) When the hot-rolled coil is initially leveled, the first-stage hydraulic rod 5016 causes the two pressure rollers 5018 to press the hot-rolled coil. Then, the bidirectional hydraulic pump 5021 can adjust the degree of stagger of each set of pressure rollers 5018, thereby bending the hot-rolled coil up and down, thereby releasing the stress on the hot-rolled coil. After the initial leveling is completed, it is sent into the hot pressing mechanism 7.

[0048] (3) The hot rolled coil is flattened by multiple heat-conducting components 703 on the hot pressing mechanism 7. At the same time, the heat-conducting components 703 are also filled with heating liquid, thereby heating the protective sleeve 7031. The flattening effect can be improved by simultaneously heating and flattening the hot rolled coil.

[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
