Description

Technical Field

[0001] This invention relates to the field of steel rolling equipment technology, specifically to a precision rolling equipment for hot-rolled steel profiles based on MES. Background Technology

[0002] MES (Manufacturing Execution System) is a computerized system used for real-time monitoring, tracking, and control of production processes. MES systems can integrate and manage production processes, resources, and data on the production line to improve production efficiency and quality, and reduce production costs. Hot-rolled steel is steel produced by heating and rolling at high temperatures. Its strength is not very high, but it is sufficient for our needs. It has good plasticity and weldability, so it is commonly used. Hot rolling involves heating the material during or before rolling, generally to above the recrystallization temperature, to roll the steel plate into a specified size. During the hot rolling process, rolling equipment is used to roll the heated steel plate.

[0003] Currently, the rolling method of hot-rolled steel precision rolling equipment based on MES mainly involves fixing the thickness of the steel plate by using two upper and lower rollers. After limiting the thickness of the steel plate, the width of the steel plate is fixed by setting rollers on both sides of the steel plate as it advances. Since excess steel will protrude from both sides at the contact point between the rollers and the steel plate during the rolling process, a limiting mechanism is needed to limit the thickness of the steel plate during the vertical rolling and horizontal rolling process to prevent its thickness deformation.

[0004] However, this method is quite complex when rolling steel plates, and it cannot roll multiple sides of the steel plate simultaneously, resulting in low rolling efficiency and thus affecting production efficiency. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Therefore, the purpose of this invention is to provide a precision rolling device for hot-rolled steel profiles based on MES, which can replace the traditional method of rolling hot-rolled steel plates. This avoids the problem that the thickness and width of the steel plate need to be rolled in stages during the hot rolling process, which leads to low rolling efficiency and affects production efficiency.

[0015] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the fixing frame includes connecting rods located on both sides of the fixing seat and a support frame located at the bottom of the connecting rods and connected to the top of the base by bolts.

[0017] The side wall of the vertical rolling plate is provided with a limiting slider that extends into the first limiting groove.

[0018] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the side wall of the vertical rolling plate is provided with an installation groove.

[0019] The drive mechanism includes a drive motor mounted on the side wall of the fixed base and a cam whose one end is connected to the output end of the drive motor and whose other end extends into the mounting groove and is hinged to the inner wall of the mounting groove.

[0020] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the surface of the connecting seat is provided with a connecting groove, and the inner wall of the connecting groove is provided with a lead screw and a slide rod.

[0021] The transverse rolling plate is threaded onto the lead screw and slidably sleeved onto the slide rod.

[0022] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the vertical rolling plate is provided with first serrated plates on both sides.

[0023] The side wall of the connecting rod is provided with a transmission component that is connected at one end to the sawtooth plate and at the other end to the lead screw.

[0024] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the transmission assembly includes a first gear mounted on the side wall of the connecting rod and meshing with the first sawtooth plate, a first helical gear set with one end connected to the side wall of the first gear, and a first pulley located at the end of the first helical gear set away from the first gear.

[0025] The end of the lead screw away from the transverse rolling plate is provided with a second pulley extending out of the connecting groove and connected to the first pulley via a belt.

[0026] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the side wall of the transverse rolling plate is provided with a second serrated plate.

[0027] The base has a drive box with a connecting frame at the bottom on its side wall, and the side wall of the connecting frame is connected to the side wall of the base.

[0028] The inner wall of the base is provided with a drive gear, a first driven gear movably connected to the inner wall of the drive box, a second driven gear located on top of the first driven gear and meshing with the drive gear, an output gear with a third pulley connected to the side wall, and a drive plate connected to the inner wall of the drive box and having a second limiting groove on its top surface.

[0029] The top of the second driven gear is provided with a limiting rod that extends into the second limiting groove;

[0031] The base is provided with a second gear on its top, which has a second helical gear set on its top and meshes with the second sawtooth plate. The end of the second helical gear set away from the second gear is connected to the drive gear through a rotating shaft.

[0032] As a preferred embodiment of the MES-based hot-rolled steel precision rolling device of the present invention, the top of the base is provided with a limiting frame on the side of the output direction of the conveying mechanism to limit the height and width of the rolled steel plate body.

[0033] Compared with the prior art, the present invention has the following advantages: This MES-based hot-rolled steel precision rolling device drives the vertical rolling plate to move downwards to press and roll the top of the steel plate body, while driving the horizontal rolling plates on both sides to move closer to each other, thereby simultaneously extruding and rolling multiple sides of the steel plate body. When rolling the steel plate body, the conveying mechanism stops working to avoid incomplete rolling caused by continuous movement of the steel plate body during the rolling process. After one side is rolled, the vertical rolling plate rises and the two horizontal rolling plates move away from each other, driving the conveying mechanism to start working, thereby conveying the steel plate body forward. This realizes that the steel plate body moves in step with the vertical and horizontal rolling plates during the rolling process, replacing the traditional hot-rolled steel plate rolling method. It avoids the problem of low rolling efficiency and reduced production efficiency caused by the need to roll the thickness and width of the steel plate step by step during the hot rolling process.

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0045] This invention provides a precision rolling device for hot-rolled steel profiles based on MES, which replaces the traditional method of rolling hot-rolled steel plates. It avoids the problem of low rolling efficiency and reduced production efficiency caused by the need to roll the thickness and width of the steel plate in stages during the hot rolling process.

[0046] Figures 1-6 The diagram shown is a structural schematic of a MES-based precision rolling apparatus for hot-rolled steel profiles according to the present invention. Please refer to [link / reference]. Figures 1-6 This paper provides a detailed introduction to this MES-based precision rolling equipment for hot-rolled steel profiles.

[0047] In some embodiments

[0048] refer to Figures 1-6 This invention discloses a precision rolling device for hot-rolled steel profiles based on MES, the main body of which includes a base 100, a vertical rolling mechanism 200, a driving mechanism 300, and a horizontal rolling mechanism 400.

[0049] refer to Figures 1-2 The base 100 is used to support the entire device and facilitate the installation of the vertical rolling mechanism 200 and the horizontal rolling mechanism 400. The top of the base 100 is provided with a conveying mechanism 110 for conveying the steel plate body 500, which is used to convey the heated steel plate body 500 to the vertical rolling mechanism 200 and the horizontal rolling mechanism 400 for rolling.

[0050] In this embodiment, reference Figures 1-2 The side wall of the base 100 is provided with a drive box 120 with a connecting frame 120a at the bottom, which is used to facilitate the transmission connection between the conveying mechanism 110 and the transverse rolling plate 420; the side wall of the connecting frame 120a is connected to the side wall of the base 100 for fixing the drive box 120.

[0051] refer to Figures 5-6 The inner wall of the drive box 120 is provided with a drive gear 120b, a first driven gear 120c movably connected to the inner wall of the drive box 120, a second driven gear 120d located on top of the first driven gear 120c and meshing with the drive gear 120b, an output gear 120e connected to the side wall of the third pulley 120e-1, and a drive plate 120f connected to the inner wall of the drive box 120 and having a second limiting groove 120f-1 on its top surface. When the drive gear 120b rotates, it drives the second driven gear 120d to rotate. When the second driven gear 120d rotates, it drives the first driven gear 120c to rotate. When the output gear 120e rotates, it drives the third pulley 120e-1 to rotate.

[0052] refer to Figure 6The top of the second driven gear 120d is provided with a limiting rod 120d-1 extending into the second limiting groove 120f-1. This rod is used when the two transverse rolling plates 420 approach each other, causing the second gear 130 and the second helical gear set 130a to rotate under the action of the second serrated plate 420a. When the second helical gear set 130a rotates, causing the drive gear 120b to rotate and the second driven gear 120d to rotate, since the first driven gear 120c is movably connected to the inner wall of the drive housing 120, the first driven gear 120c and the second driven gear 120d slide along the limiting groove, allowing... The first driven gear 120c separates from the output gear 120e. After the output gear 120e stops rotating, the conveying mechanism 110 stops working, which facilitates the steel plate body 500 to stop being rolled. Similarly, when the steel plate body 500 is rolled and the two transverse rolling plates 420 move away from each other, the first driven gear 120c and the second driven gear 120d slide in opposite directions along the limiting slide groove, so that the first driven gear 120c meshes with the output gear 120e and drives the output gear 120e to rotate, which in turn drives the conveying mechanism 110 to start working and drive the rolled steel plate body 500 forward.

[0053] refer to Figures 1-2 The side wall of the conveying roller of the conveying mechanism 110 is provided with a drive shaft 110a. The side wall of the drive shaft 110a is connected to a fourth pulley 110a-1, which is connected to the third pulley via a belt. When the third pulley 120e-1 rotates, it drives the third pulley 120e-1 to rotate, thereby driving the conveying roller of the conveying mechanism 110 to rotate and convey the steel plate body 500.

[0054] refer to Figures 1-2 The top of the base 100 is provided with a second gear 130 having a second helical gear set 130a on its top and meshing with the second serrated plate 420a. When the transverse rolling plate 420 moves, it drives the second serrated plate 420a to move. When the second serrated plate 420a moves, it drives the second gear 130 to rotate. When the second gear 130 rotates, it drives the second helical gear set 130a to rotate. The end of the second helical gear set 130a away from the second gear 130 is connected to the drive gear 120b through a rotating shaft, so that when the second helical gear set 130a rotates, it drives the drive gear 120b to rotate.

[0055] refer to Figures 1-3 The vertical rolling mechanism 200 is used to press down on the top of the steel plate body 500 to roll its thickness. The vertical rolling mechanism 200 is located on the top of the base 100 and includes a fixed seat 210 mounted on the top of the base 100 and a vertical rolling plate 220 movably connected to the fixed seat 210. The vertical rolling plate 220 presses down to roll the top of the steel plate body 500.

[0056] In this embodiment, reference Figures 1-3 The fixed base 210 is provided with fixed brackets 210a on both sides, which are connected to the top of the base 100, for fixing the fixed base 210 and thus fixing the vertical rolling mechanism 200.

[0057] In this embodiment, reference Figure 3 The fixing frame 210a includes connecting rods 210a-1 located on both sides of the fixing seat 210 and a support frame 210a-2 located at the bottom of the connecting rods 210a-1 and connected to the top of the base 100 by bolts. The fixing seat 210 is detachably installed on the top of the base 100 by the cooperation of the connecting rods 210a-1 and the support frame 210a-2.

[0058] In this embodiment, reference Figure 3 The side wall of the fixed base 210 is provided with a first limiting groove 210b;

[0059] refer to Figure 3 The side wall of the vertical rolling plate 220 is provided with a limiting slider 220a extending into the first limiting groove 210b. When the drive motor 310 drives the cam 320 to rotate, the vertical rolling plate 220 is made to rise and fall linearly under the action of the first limiting groove 210b and the limiting slider 220a, thereby facilitating the rolling of the top of the steel plate body 500.

[0060] In this embodiment, reference Figure 3 The side wall of the vertical rolling plate 220 is provided with a mounting groove 220b for easy hinge connection with the cam 320;

[0061] In this embodiment, reference Figures 1-3 The vertical rolling plate 220 is provided with first serrated plates 220c on both sides, which are used to drive the first serrated plates 220c to move up and down when the vertical rolling plate 220 moves.

[0062] refer to Figures 1-3 The side wall of the connecting rod 210a-1 is provided with a transmission assembly 210a-11, one end of which is connected to the first sawtooth plate 220c and the other end of which is connected to the lead screw 410a-1. This assembly is used to drive the lead screw 410a-1 to rotate when the first sawtooth plate 220c moves up and down.

[0063] In this embodiment, reference Figure 2The transmission assembly 210a-11 includes a first gear 210a-111 mounted on the side wall of the connecting rod 210a-1 and meshing with the first serrated plate 220c, a first helical gear set 210a-112 with one end connected to the side wall of the first gear 210a-111, and a first pulley 210a-113 located at the end of the first helical gear set 210a-112 away from the first gear 210a-111. When the first serrated plate 220c moves up and down, it drives the first gear 210a-111 to rotate. When the first gear 210a-111 rotates, it drives the first helical gear set 210a-112 to rotate. When the first helical gear set 210a-112 rotates, it drives the first pulley 210a-113 to rotate.

[0064] refer to Figures 1-3 The drive mechanism 300 is mounted on the fixed base 210. When the drive mechanism 300 is working, it drives the vertical rolling plate 220 to move up and down along the fixed base 210, thereby rolling the top of the steel plate.

[0065] In this embodiment, reference Figure 3 The drive mechanism 300 includes a drive motor 310 mounted on the side wall of the fixed base 210 and a cam 320 whose one end is connected to the output end of the drive motor 310 and whose other end extends into the mounting groove 220b and is hinged to the inner wall of the mounting groove 220b. When the drive motor 310 is working, it drives the cam 320 to rotate. When the cam 320 rotates, it drives the vertical rolling plate 220 to move up and down reciprocally under the limiting action of the limiting slider 220a and the limiting groove, thereby rolling the top of the steel plate body 500.

[0066] refer to Figures 1-2 and Figure 4 The transverse rolling mechanism 400 is used to extrude both sides of the steel plate body 500, thereby rolling the width of the steel plate body 500. The transverse rolling mechanism 400 is installed on both sides of the top of the base 100. The transverse rolling mechanism 400 includes a connecting seat 410 installed on the side wall of the base 100 and a transverse rolling plate 420 movably installed on the connecting seat 410.

[0067] When the vertical rolling plate 220 moves downward along the fixed base 210, the two horizontal rolling plates 420 approach each other and the conveying mechanism 110 stops working. This is used to stop the conveying mechanism 110 from conveying the steel plate body 500. At the same time, the two horizontal rolling plates 420 approach each other and squeeze the two sides of the steel plate body 500, thereby rolling the width of the steel plate body 500. When the vertical rolling plate 220 moves upward along the fixed base 210, the two vertical rolling plates 220 move away from each other and the conveying mechanism 110 starts working. This is used to drive the steel plate body 500 to continue conveying after the rolling is completed. This allows the steel plate body 500 to move forward in coordination with the vertical rolling mechanism 200 and the horizontal rolling mechanism 400.

[0068] In this embodiment, reference Figure 4 The surface of the connecting seat 410 is provided with a connecting groove 410a for easy installation of the lead screw 410a-1 and the slide rod 410a-2. The inner wall of the connecting groove 410a is provided with the lead screw 410a-1 and the slide rod 410a-2, which are used to drive the transverse rolling plate 420 to move along the lead screw 410a-1 and the slide rod 410a-2 under the limiting action of the slide rod 410a-2 when the lead screw 410a-1 rotates.

[0069] refer to Figure 4 The transverse rolling plate 420 is threaded onto the lead screw 410a-1 and slidably sleeved onto the slide rod 410a-2. When the lead screw 410a-1 rotates, the transverse rolling plate 420 moves along the lead screw 410a-1 and the slide rod 410a-2 under the limiting action of the slide rod 410a-2. Thus, the two transverse rolling plates 420 move closer or further away from each other to achieve extrusion rolling on both sides of the steel plate body 500.

[0070] In this embodiment, reference Figure 4 The end of the lead screw 410a-1 away from the transverse rolling plate 420 is provided with a second pulley 410a-11 extending out of the connecting groove 410a and connected to the first pulley 210a-113 by a belt. When the first pulley 210a-113 rotates, it drives the second pulley 410a-11 to rotate, which in turn drives the lead screw 410a-1 to rotate.

[0071] In this embodiment, the specific usage process is as follows: The heated steel plate body 500 is conveyed to the vertical rolling mechanism 200 and the horizontal rolling mechanism 400 by the conveying mechanism 110. The vertical rolling plate 220 is driven to descend by the driving mechanism 300 to perform vertical rolling on the steel plate body 500. When the vertical rolling plate 220 descends, it drives the two horizontal rolling plates 420 to move closer to each other to squeeze and roll the two sides of the steel plate body 500, thereby completing the simultaneous rolling of multiple sides of the steel plate body 500, which improves the rolling efficiency of the steel plate body 500. During the rolling process, the conveying mechanism 110 drives the steel plate body 500 to move in step with the vertical rolling mechanism 200 and the horizontal rolling mechanism 400, thereby avoiding incomplete rolling caused by the continuous movement of the steel plate body 500 during the rolling process.

[0072] In other embodiments

[0073] refer to Figures 1-2 The top of the base 100 is provided on one side of the output direction of the conveying mechanism 110. A limiting frame is provided to limit the height and width of the rolled steel plate body 500. This is used to limit part of the rolled steel plate body 500 to prevent the steel material that is squeezed during the subsequent rolling process from forming a protrusion in part of the rolled steel plate body 500, which would result in poor quality of the rolled steel plate.

[0074] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
