Description

Technical Field

[0001] The present application specifically relates to a rolling equipment for tin phosphor bronze plates, belonging to the technical field of metal rolling. Background Art

[0002] The copper plate rolling process usually includes multiple stages such as hot rolling, medium rolling and finish rolling. During the whole process, the copper plate (strip) runs continuously in a long strip shape. During rolling and transmission, due to factors such as equipment precision deviation, uneven tension or external disturbance, the copper plate (strip) is prone to lateral position deviation, which in turn causes quality problems such as edge defects and uneven thickness, seriously affecting the yield and surface quality of the product. Therefore, during continuous production, an efficient and stable deviation rectification device must be equipped to adjust the running position of the copper plate (strip) in real time to ensure its centering and stability during rolling.

[0003] At present, there are mainly two deviation rectification methods in the existing technology: baffle deviation rectification and single-roll deviation rectification. Among them, the baffle deviation rectification has a simple structure and stable control, and is suitable for the rough rolling stage with relatively low precision requirements, especially suitable for the treatment of thick plates; however, this method realizes deviation rectification through physical contact, and there are problems such as easy wear at the contact part and affecting the edge quality of the copper plate. The single-roll deviation rectification has the advantages of fast response speed and high deviation rectification precision, can meet the high-precision requirements of the finish rolling stage, and is suitable for the deviation rectification operation of thin plates, but its system structure is complex, and the manufacturing and maintenance costs are relatively high, which limits its wide application in some production scenarios. With the ability of rolling equipment to meet the rolling requirements of plates (strips) with different thicknesses through parameter adjustment, how to quickly switch the deviation rectification method suitable for the corresponding plate thickness has become the key. However, the existing deviation rectification methods are independent of each other, and the replacement operation is inconvenient, making it difficult to flexibly adapt to the changes in production requirements.

[0004] In view of the above problems, there is an urgent need to develop an integrated deviation rectification device that can be compatible with the deviation rectification requirements of thick plates and thin plates, and can automatically match the optimal deviation rectification mode according to the actual working conditions, so as to achieve efficient, accurate and continuous deviation rectification control, and improve the automation level and adaptability of the overall production line.

As the mill continues to roll the plate, it is gradually rolled from the feed port to the discharge port and discharged by a conveyor mechanism. During the rolling process, due to the plate's thick and uneven thickness or the influence of different frictional forces, the feed path may deviate, resulting in lateral movement toward one baffle. In this case, the baffle blocks the plate's deviation and withstands the resulting lateral extrusion force. This extrusion force pushes the baffle outward, driving the extrusion column on the baffle along the sliding groove and shifting the shifting seat. The shifting seat, under the force, pushes one end of the deviation correction roller assembly toward the feed port, thereby adjusting the position of the deviation correction roller assembly. The corrective rollers located at the bottom of the sheet material are able to apply appropriate roller force to gradually correct the deflected sheet material back to the correct feeding direction. Together with the baffle, this automatically corrects the sheet material's feeding path. For thinner sheets, the automatic correction mode, which utilizes only the corrective rollers and sensors, can meet the correction requirements.

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0023] The following describes tin-phosphorus bronze plate rolling equipment provided according to some embodiments of the present application with reference to FIG. 1 to FIG. 10 .

[0024] In one possible implementation, see Figure 1 、 Figure 2 and Figure 8; including: a mill 100; a conveying mechanism 200, arranged at the discharge end of the mill 100, for conveying the material after being rolled by the mill 100; a correction device platform 300, arranged at the feed end of the mill 100; a limit assembly 310 capable of adjusting displacement is provided on the correction device platform 300; a baffle correction mechanism 400, including a pair of baffles 410 symmetrically arranged on both sides of the feed direction of the correction device platform 300; the baffles 410 are connected to the top of the limit assembly 310, and the distance between the baffles 410 is adjustable to adapt to materials of different widths; a single roller correction mechanism 500, installed on the correction device platform 300, including: a horizontally arranged cylindrical correction roller group 510; the correction roller group 510 The upper surface contacts the material plate; the correction adjustment mechanism 600, one end of which is connected to the baffle correction mechanism 400 and the other end is connected to the single-roller correction mechanism 500; it includes: an extrusion column 610, which extends from the baffle 410 through an adjustment screw 630; a toggle seat 620, the bottom end of which is connected to one end of the correction roller group 510; the toggle seat 620 is mounted on the bottom end of the extrusion column 610 through a long sliding groove 621, and forms an extension path along the direction close to the discharge port at an acute angle to the feeding direction.

[0025] In this embodiment, a bronze plate is laid into the feed port of the mill 100, its bottom surface in contact with the guide roller assembly 510, and its ends are restrained by baffles 410. As the mill 100 continues rolling the plate, it is gradually rolled from the feed port to the discharge port and discharged by the conveyor mechanism 200. During the rolling process, due to the plate's thick and uneven thickness or the influence of varying friction, the plate may deviate from the feed path, resulting in lateral movement toward one side of the baffle 410. In this case, the baffle 410 can prevent the plate from deviating and withstand the resulting lateral extrusion force. This extrusion force pushes the baffle 410 outward, driving the extrusion column 610 on the baffle 410 along the sliding groove 621 and shifting the shifting seat 620. When applied force, the toggle seat 620 pushes one end of the correcting roller assembly 510 toward the feed inlet, thereby adjusting the position of the correcting roller assembly 510. Positioned at the bottom of the sheet material, the correcting roller assembly 510 can thus apply appropriate roller force to gradually correct any deviations in the sheet material back to the correct feeding direction. Together with the baffle 410, this automatically corrects the sheet material's feed path. For thinner sheets, the automatic correction mode, which utilizes only the correcting roller assembly 510 in conjunction with the sensor, can meet corrective needs.

[0026] In one embodiment, see Figure 2 and Figure 3, the deviation rectifying device table 300 further includes: a deviation rectifying base 320; disposed below the limiting component 310; the limiting component 310 can slide on the deviation rectifying base 320 in a direction perpendicular to the feeding moving line; a vertical frame 330, vertically disposed at the four corners of the deviation rectifying base 320 respectively, for supporting and installing the single-roller deviation rectifying mechanism 500.

[0027] In this embodiment, the deviation rectifying base 320 is a rectangular structure, and vertical frames 330 with the same height are respectively provided at its four corners. Each pair of vertical frames 330 is arranged horizontally for installing the tension roller group 550. Both ends of the tension roller group 550 are connected to the upper part of the vertical frame 330 and can rotate by itself. The limiting component 310 is disposed on the deviation rectifying base 320 and can slide along the axis perpendicular to the feeding direction to adjust its position. The limiting distance formed inside the limiting component 310 can be adjusted as needed, and the width between the baffle deviation rectifying pieces 410 of the baffle 410 is adjusted through the change of this distance, so as to realize the function of flexibly adapting to the width of the material plate.

[0028] In a possible implementation manner, please refer to Figure 3 , Figure 4 and Figure 5 , the limiting component 310 includes: a moving frame 311, symmetrically slidably disposed on both sides of the deviation rectifying base 320 in the feeding direction; an opposed lead screw 312, rotatably passing through between a pair of moving frames 311, and opposite-handed threads are provided at both ends of the opposed lead screw 312, which are in threaded fit with the internal threads of the mounting holes on the moving frame 311; at least one motor 313, mounted on the side of the moving frame 311 away from the opposed lead screw 312, and its output shaft is in transmission connection with the opposed lead screw 312; a first fixing seat 314, disposed between the motor 313 and the moving frame 311, and its bottom end is fixedly connected to the deviation rectifying base 320; a limiting block 315; one end is fixed to the top end of the moving frame 311, and the other end is connected to the baffle 410.

[0029] In this embodiment, in a possible implementation manner, the limiting component 310 includes a plurality of adjustable structural components, which cooperate to realize the self-adaptive adjustment function of the baffle deviation rectifying mechanism 400 in the width direction.

[0030] Specifically, the limiting component 310 mainly includes a pair of moving frames 311 symmetrically arranged on both sides of the deviation rectifying base 320 in the feeding direction, an opposed lead screw 312 passing through the two moving frames 311 and threadedly engaged therewith, a motor 313 for providing driving force, a first fixing seat 314 for supporting and fixing, and a limiting block 315 connecting the baffle 410. This structural design is compact and operates flexibly, and can quickly adjust the distance between the baffles 410 according to the change in the width of the material plate, thereby improving the applicability and automation level of the equipment.

[0031] In the initial state, a certain initial distance is maintained between the two moving frames 311. When it is necessary to adjust the width between the baffles 410, the motor 313 is started, and its output shaft drives the opposed lead screw 312 to rotate through a transmission device. Since the two ends of the opposed lead screw 312 are provided with threads with opposite helix directions, when the lead screw rotates, the two moving frames 311 will synchronously open outwards or approach inwards, realizing the two-way adjustment of the distance. This symmetric driving method not only improves the adjustment accuracy but also enhances the stability of the system.

[0032] Furthermore, the motor 313 is installed on the side of the moving frame 311 away from the opposed lead screw 312 and is firmly connected through the first fixing seat 314. The fixing seat has a right-angled bending structure, with one end clamped between the motor 313 and the moving frame 311, and the other end firmly fixed on the deviation rectifying base 320, ensuring that the entire driving system will not displace or shake during operation, thereby guaranteeing the smoothness and reliability of the adjustment process.

[0033] In addition, limiting blocks 315 are provided at both ends of each moving frame 311 along the feeding direction, and the top of the limiting block 315 is connected to the baffle 410 in the baffle deviation rectifying mechanism 400. When the moving frame 311 moves with the opposed lead screw 312, the limiting block 315 moves accordingly, and then drives the baffle 410 to move synchronously, realizing the precise adjustment of the distance between the baffles 410. This linkage mechanism not only improves the automation level of the equipment but also provides good adaptability for tin phosphor bronze plates of different width specifications.

[0034] The limiting component 310 realizes bilateral synchronous adjustment by driving the opposed lead screw 312 through the motor 313. Combining the connection structure between the limiting block 315 and the baffle 410, it realizes the dynamic control of the width of the baffle deviation rectifying mechanism 400, thereby effectively coping with the width change and offset problems of the material plate during the feeding process, and significantly improving the working efficiency and processing accuracy of the equipment.

[0035] In a possible implementation manner, please refer to Figure 6, the baffle 410 includes: a wear-resistant baffle 411; a mounting frame 412, and a plurality of wear-resistant baffles 411 are sequentially inserted into the mounting frame 412.

[0036] In this embodiment, the baffle 410 includes a wear-resistant baffle 411 and a mounting frame 412, and a plurality of wear-resistant baffles 411 are sequentially fixed to the mounting frame 412 by insertion. Matching interface structures are provided between each wear-resistant baffle 411, facilitating quick disassembly, replacement, and improving the convenience of equipment maintenance. During actual operation, the wear-resistant surface of the wear-resistant baffle 411 is arranged towards the feed inlet direction. When the material plate deviates during the feeding process, its edge will first contact and press the surface of the wear-resistant baffle 411, thereby triggering a deviation correction action. This modular design not only improves the durability of the baffle 410 assembly but also facilitates flexible adjustment of the length or position of the baffle 410 according to the material specifications to adapt to tin phosphor bronze plates of different widths.

[0037] In a possible implementation manner, please refer to Figure 6 , the baffle deviation correction mechanism 400 further includes: a movable member 420, extending outward from the side of the baffle 410 facing away from the feed inlet and movably passing through the top of the limit assembly 310; a spring 430, sleeved on the movable member 420, forming a telescopic space between the baffle 410 and the limit assembly 310.

[0038] In this embodiment, this structure has a dual function: on the one hand, when adjusting the distance between the baffles 410, the movable member 420 can slide within the limit block 315 to achieve the synchronous movement of the baffle 410 with the limit assembly 310, ensuring a stable and reliable adjustment process; on the other hand, when the material plate undergoes lateral deviation due to uneven thickness or friction difference and impacts the baffle 410, the baffle 410 will be forced to retract outward, driving the movable member 420 to extend out of the limit block 315 while compressing the spring 430. At this time, the spring 430 plays a role of buffering and absorbing energy, avoiding damage to the baffle 410 due to excessive force and reducing the impact of rigid collision on the material plate, improving the stability and safety of the deviation correction process.

[0039] In a possible implementation manner, please refer to Figure 7 and Figure 8 and Figure 10The single-roller correction mechanism 500 also includes: a correction cylinder 520, which is arranged at both ends of the correction roller group 510 through a connecting seat 530, and is used to drive at least one end of the correction roller group 510 to move or return; a second fixed seat 540, one end of which is connected to the correction device platform 300, and the other end is connected to the correction cylinder 520; a tensioning roller group 550, both ends of which are respectively arranged at the top of a pair of vertical frames 330, and are parallel to the correction roller group 510; a tensioning cylinder 560, which is arranged at both ends of the tensioning roller group 550, and is used to provide tensioning force.

[0040] Specifically, in this embodiment, the correcting cylinder 520 is mounted on both ends of the correcting roller assembly 510 via a connecting base 530, capable of driving at least one end thereof for axial displacement or return. A second fixing base 540 is fixed to the correcting device platform 300 at one end and connected to the correcting cylinder 520 at the other end, ensuring stability and positioning accuracy during operation of the entire system.

[0041] The correction roller set 510 has two working modes, active correction mode and passive correction mode: Active correction mode is suitable for thinner or narrower sheets. In this mode, the output shaft of correction cylinder 520 retracts and extends, causing a slight deflection on one end of correction roller assembly 510, causing its rolling axis to adjust in the opposite direction of the sheet's deflection. This provides a guiding torque, gradually correcting the sheet to the correct feeding path. Compared to the rigid stopper of baffle 410, the flexible correction method of correction roller assembly 510 is gentler and more precise, making it particularly suitable for thin materials requiring high processing precision.

[0042] Passive correction mode is suitable for thicker or more rigid sheet materials. When the sheet material deflects and strikes the baffle 410, the applied force pushes the extrusion column 610 along the sliding groove 621, which in turn displaces the toggle seat 620. Because the toggle seat 620 is connected to one end of the correction roller assembly 510 and its motion path forms a certain angle with the feed direction, it generates a force component that causes the correction roller assembly 510 to deflect axially, achieving automatic correction. In this mode, no active hydraulic cylinder intervention is required; correction is accomplished through mechanical linkage, resulting in rapid response, energy efficiency, and high efficiency.

[0043] In addition, the tensioning roller set 550 is arranged at the top of the vertical frames 330 on the front and rear sides of the deviation rectifying roller set 510, and is arranged in parallel with the deviation rectifying roller set 510. The lower surface thereof is lower than the upper surface of the deviation rectifying roller set 510, so that the material plate forms a slightly wavy structure during the feeding process, which helps to enhance the tensioning effect. The tensioning oil cylinder 560 is installed above both ends of the tensioning roller set 550, and controls the up and down height of the roller set through a telescopic output shaft, thereby adjusting the tension applied to the material plate to ensure that it remains flat and stable during the entire rolling process.

[0044] In a possible implementation manner, please refer to Figure 9 , one end of the adjusting screw 630 is sleeved on the column body of the extrusion column 610 through an annular movable sleeve 631, and the other end passes through the baffle 410 and is fixed by a nut. The adjusting screw 630 is provided with an external thread for adjusting the distance between the baffle 410 and the extrusion column 610.

[0045] In this embodiment, in this implementation manner, one end of the adjusting screw 630 in the deviation rectifying adjusting mechanism 600 is sleeved on the column body of the extrusion column 610 through an annular movable sleeve 631, and the other end passes through the baffle 410 and is fixed by a nut. The adjusting screw 630 is provided with an external thread, and the relative distance between the baffle 410 and the extrusion column 610 can be finely adjusted through a rotation operation. This structural design allows users to flexibly adjust the linkage relationship between the baffle 410 and the deviation rectifying roller set 510 according to the thickness of different materials and the deviation rectifying requirements, thereby optimizing the deviation rectifying sensitivity and response speed and improving the overall adaptability of the equipment.

[0046] In a possible implementation manner, please refer to Figure 1 and Figure 2 , the conveying mechanism 200 includes multiple rollers distributed in parallel.

[0047] In this embodiment, the conveying mechanism 200 is composed of multiple rollers arranged in parallel, with uniform distribution and stable operation. After the rolled material plate is output from the discharge port, it is laid flat on the rollers and is smoothly conveyed to the next process through the continuous rotation of the rollers. This structure not only improves the discharge efficiency but also helps to reduce the risk of deformation of the material plate during the conveying process.

[0048] In a possible implementation manner, it is characterized in that the output shaft of the deviation rectifying oil cylinder 520 is a telescopic output shaft.

[0049] In this embodiment, the output shaft of the correction cylinder 520 utilizes a telescopic design, enabling precise control of the axial displacement of the correction roller assembly 510 based on actual correction needs. This structure offers fast response and high control accuracy, making it suitable for a wide range of material thicknesses and correction scenarios, providing a higher degree of automation and flexibility for the equipment.

[0050] In an embodiment, the device is further equipped with sensors for monitoring the thickness and deflection state of the material sheet.

[0051] In this embodiment, the device is also equipped with a sensor assembly for monitoring the thickness and deflection of the material sheet. This sensor collects real-time thickness data of the material sheet and determines whether it is experiencing lateral deflection. Based on this information, the system intelligently switches the operating mode (active or passive) of the correction cylinder 520, thereby achieving adaptive correction control for different material characteristics.

[0052] For example, for thin or narrow sheet materials, the system automatically activates active correction mode, using correction roller set 510 to provide precise guidance. For thicker or more rigid materials, however, passive correction mode is activated, relying on the linkage between baffle plate 410 and correction roller set 510 for efficient correction. This intelligent control strategy significantly enhances the equipment's applicability and processing stability.

[0053] The tin-phosphorus bronze plate rolling equipment provided in this embodiment is compatible with the deviation correction requirements for both thick and thin plates. It can automatically select the optimal deviation correction mode based on actual operating conditions, achieving precise deviation correction. During operation, a bronze plate is laid into the mill's feed port, its bottom surface in contact with the deviation correction roller assembly, and its ends are restrained by baffles on either side. As the mill continues to roll the plate, it is gradually rolled from the feed port to the discharge port and discharged by a conveyor mechanism. During the rolling process, due to the plate's thick and uneven thickness or the influence of different frictional forces, the feed path may deviate, resulting in lateral movement toward one baffle. In this case, the baffle blocks the plate's deviation and withstands the resulting lateral extrusion force. This extrusion force pushes the baffle outward, driving the extrusion column on the baffle along the sliding groove and shifting the shifting seat. The shifting seat, under pressure, pushes one end of the deviation correction roller assembly toward the feed port, thereby adjusting the position of the correction roller assembly. The corrective rollers located at the bottom of the sheet material are able to apply appropriate roller force to gradually correct the deflected sheet material back to the correct feeding direction. Together with the baffle, this automatically corrects the sheet material's feeding path. For thinner sheets, the automatic correction mode, which utilizes only the corrective rollers and sensors, can meet the correction requirements.
