Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling equipment, and in particular to a head-end baffle device and a bar conveying line. Background Technology
[0002] The trimming baffle in the bar mill's collection area is a crucial piece of equipment in the finishing zone. Its main function is to trim the finished wire rods after cold shearing and length setting, preparing them for the next bundling process. The reliable operation of the trimming baffle plays a vital role in the quality of the large bundles of finished wire rods. Currently, the trimming baffle in the bar mill uses a lifting structure, with a cylinder driving a swing arm to raise and lower the baffle. The trimming baffle has two main positions: a working position and a waiting position. Its working principle is as follows: When the cylinder piston rod extends, the baffle is in the working position, and the finished wire rod moves forward via the transmission rollers, impacting the trimming baffle to complete the forward trimming; when the cylinder piston rod retracts, the trimming baffle is in the waiting position, and the finished wire rod moves through the trimming baffle to the other side. Then, the trimming baffle falls again, and the roller conveyor reverses its direction, completing the trimming of the other end of the finished wire rod.
[0003] This type of flush-end movable baffle has a simple structure, but it has a high failure rate under the impact load of finished wire. The main reasons are as follows: the load is large when the cylinder drives the baffle to move up and down, the action cycle of the flush-end movable baffle is long, which affects the production rhythm of the workshop; the flush-end movable baffle and the baffle support adopt sliding friction, the friction coefficient is large, the operation is blocked, and the service life of the cylinder is short; the contact surface of the sliding position is prone to wear, which causes the baffle to not rise and fall in place, resulting in a high failure rate. Summary of the Invention
[0004] This invention addresses the problems of high cylinder load during the vertical movement of the baffle and the impact of steel bars in current baffle systems by providing a baffle device.
[0005] To solve the above problems, the technical solution adopted by this utility model is a flush-end baffle device, including a baffle body, a base assembly, and a push-pull assembly. The base assembly includes two clamping plates, which are parallel to each other and spaced a certain distance apart. The baffle body is located between the two clamping plates, and a guide wheel seat is also provided between the two clamping plates. The guide wheel seat is located at the lower part of the area where the clamping plates are located, and a lower guide wheel is installed on the guide wheel seat. The bottom edge of the baffle body is in rolling contact with the lower guide wheel. The push-pull assembly is located on one side of the base assembly, and the moving end of the push-pull assembly is connected to the side edge of the baffle body. A buffer is also provided on the two clamping plates, and the buffer is located between the clamping plates and the baffle body. This solution optimizes the operating structure of the flush-end baffle. The baffle moves horizontally left and right. The push-pull assembly is located on one side of the baffle body and the base assembly. The weight of the baffle acts on the base assembly, reducing the operating load on the cylinder, facilitating equipment maintenance, and extending the service life of the cylinder.
[0006] As a preferred embodiment of the flush-end baffle device, the push-pull assembly includes a cylinder mounting base on which a telescopic cylinder is mounted. A push-pull rod is provided at the end of the cylinder rod of the telescopic cylinder. One end of the push-pull rod is hinged to the cylinder rod of the telescopic cylinder, and the other end is hinged to the side edge of the baffle body. Using a hinged push-pull rod to connect the telescopic cylinder and the baffle body allows for flexible power transmission, effectively buffering impact forces during movement and avoiding component damage that may result from rigid connections. Simultaneously, this structure makes the force distribution on the telescopic cylinder more uniform, further reducing the cylinder's operating load, improving the reliability and stability of the push-pull assembly, extending the service life of each component, and reducing equipment maintenance frequency.
[0007] As a preferred embodiment of the flush-end baffle device, the top edge of the clamping plate is provided with multiple upper guide wheels. The rotation axis of the upper guide wheels is arranged vertically, and the side circumferential surface of the upper guide wheels is at least partially located between two clamping plates. On each clamping plate, multiple upper guide wheels are arranged horizontally. The multiple upper guide wheels increase the support and guidance for the top of the baffle body, improve the stability and straightness of the baffle body during operation, reduce the swaying of the baffle body, reduce wear between the baffle body and the clamping plates, extend the service life of the baffle body and the clamping plates, and make the movement of the baffle body smoother.
[0008] As a preferred embodiment of the flush-end baffle device, the clamping plate has multiple mounting windows, and multiple central guide wheels are also mounted on the clamping plate. The central guide wheels are located in the mounting windows, and at least part of the side circumferential surface of the central guide wheels is located between two clamping plates. On each clamping plate, multiple central guide wheels are arranged horizontally. The arrangement of the central guide wheels can effectively distribute the force on the baffle body during movement, and in conjunction with the upper and lower guide wheels, form a comprehensive support and guidance system for the baffle body, greatly enhancing the stability of the baffle body during operation.
[0009] As a preferred embodiment of the baffle device, the buffer is a disc spring. This effectively reduces vibration and noise generated by collisions or impacts during operation of the baffle body, protecting the structural integrity of the baffle body and base assembly. Simultaneously, the disc spring has a long service life, low maintenance costs, and reduces wear between components by absorbing impact forces.
[0010] As a preferred implementation of the flush-end baffle device, four buffer elements are provided on each clamp, arranged in a rectangular pattern. This allows for more comprehensive and balanced absorption and dispersion of impact forces, significantly improving the buffering effect and stability compared to a single or fewer buffer elements. It ensures effective buffering protection for the baffle body in all directions, further enhancing the flush-end baffle device's ability to resist external impacts, extending the equipment's service life, and guaranteeing the reliability and safety of the equipment during operation.
[0011] On the other hand, this utility model also provides a bar conveying line, including a conveying device for driving the bar conveying, and the aforementioned end-aligning baffle device, which is located at a predetermined position in the bar conveying direction. Applying the end-aligning baffle device to the bar conveying line can effectively perform end-aligning processing on the bars during the conveying process, improving the conveying quality and processing accuracy of the bars.
[0012] As a preferred implementation of a bar conveying line, the conveying device includes multiple conveying rollers arranged along the bar conveying direction, with the end-aligning baffle device located between two adjacent conveying rollers, and the upper edge of the baffle not exceeding the highest point of the conveying roller. This reasonable positioning and height relationship optimizes the overall structural layout of the bar conveying line, improving the reliability and stability of equipment operation.
[0013] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: The flush-end baffle operating structure of this solution enables the baffle to move horizontally left and right. The push-pull component is placed on the side, and the weight of the baffle acts on the base component, which greatly reduces the operating load of the cylinder. The hinged push-pull rod further optimizes the force on the cylinder. With the coordinated work of the upper, middle, and lower guide wheels, the stability and straightness of the baffle operation are effectively improved, shaking is reduced, friction loss is reduced, and the baffle moves smoothly, ensuring the accuracy and efficiency of flush-end operation. In terms of structural reliability, the disc springs and four rectangularly arranged disc spring buffers can effectively absorb and disperse impact forces, reduce vibration and noise, protect the baffle body and base component structure, and enhance the impact resistance of the device. The reasonable design and cooperation between the components form a stable operating system, ensuring long-term stable operation of the equipment. In terms of maintenance costs, the above design greatly reduces component wear, extends the service life of each component and the overall device, reduces the frequency of equipment maintenance, and the installation window design facilitates the installation and disassembly of components such as the middle guide wheel, making it convenient for later maintenance and replacement, and effectively saving maintenance costs. In terms of production quality, applying the end-aligning baffle device to the bar conveying line can accurately align the bars, significantly improving the bar conveying quality and processing accuracy. Furthermore, the reasonable position and height setting of the end-aligning baffle device and the conveying rollers prevents the bars from being scratched or deformed, optimizes the overall layout, and improves production efficiency and product quality.

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0019] Example 1 like Figure 1 As shown, a baffle device includes a baffle body 2, a base assembly, and a push-pull assembly: like Figure 2 As shown, the base assembly includes two clamping plates 4, which are parallel to each other and spaced a certain distance apart. The baffle body 2 is located between the two clamping plates 4, and a guide wheel seat 5 is also provided between the two clamping plates 4. The guide wheel seat 5 is located at the lower part of the area where the clamping plates 4 are located, and a lower guide wheel 3 is installed on the guide wheel seat 5. The bottom edge of the baffle body 2 is in rolling contact with the lower guide wheel 3. The push-pull assembly is located on one side of the base assembly, and the moving end of the push-pull assembly is connected to the side edge of the baffle body 2. The two clamping plates 4 are also provided with buffer members 11, which are located between the clamping plates 4 and the baffle body 2. In this embodiment, the buffer member 11 is a disc spring. Four buffer members 11 are provided on each clamping plate 4, and the four buffer members 11 are arranged in a rectangular shape. The top edge of the clamping plate 4 is provided with a plurality of upper guide wheels 8, the rotation axis of the upper guide wheels 8 is set in the vertical direction, and the side circumferential surface of the upper guide wheels 8 is at least partially located between two clamping plates 4. On each clamping plate 4, a plurality of upper guide wheels 8 are arranged in the horizontal direction. The clamping plate 4 is provided with a plurality of installation windows 9, and a plurality of middle guide wheels 10 are also installed on the clamping plate 4. The middle guide wheels 10 are located in the installation windows 9, and the side circumferential surface of the middle guide wheels 10 is at least partially located between two clamping plates 4. On each clamping plate 4, a plurality of middle guide wheels 10 are arranged in the horizontal direction.
[0020] The push-pull assembly includes a cylinder mounting base 6, on which a telescopic cylinder 1 is mounted. The cylinder rod end of the telescopic cylinder 1 is provided with a push-pull rod 7. One end of the push-pull rod 7 is hinged to the cylinder rod of the telescopic cylinder, and the other end of the push-pull rod 7 is hinged to the side edge of the baffle body 2.
[0021] When the baffle body needs to move, the telescopic cylinder is activated, and the cylinder rod extends or retracts, driving the push-pull rod to move. Since the two ends of the push-pull rod are hinged to the cylinder rod and the baffle body respectively, the rotation of the hinge points converts the telescopic cylinder's extension and retraction motion into a push-pull action on the baffle body, causing the baffle body to move horizontally left and right on the base assembly, thus controlling the alignment of the head. During horizontal movement, the top of the baffle body contacts the side circumference of the upper guide wheel, and the middle of the baffle body contacts the side circumference of the middle guide wheel. As the baffle body moves, the upper guide wheel rotates on the vertical axis of rotation, guiding the baffle body to move smoothly horizontally through rolling friction, limiting the baffle body's offset perpendicular to the direction of movement, and ensuring stable operation of the baffle body between the clamps. When the baffle body is in position and impacted by an external steel rod, the baffle body compresses the disc spring located between the clamp and the baffle body. Disc springs have good elastic properties and can absorb and buffer impact forces through their own elastic deformation, reducing the direct impact force on the baffle body and clamping plate.
[0022] Example 2 This embodiment further provides a bar conveying line, including a conveying device for driving the bar conveying, and also includes the end-cutting baffle device described in Embodiment 1, such as... Figure 2 As shown, the end-cutting baffle device is located at a predetermined position in the bar conveying direction, and the conveying device includes components along the bar conveying direction (i.e., Figure 2 Multiple conveying rollers 12 are arranged in the vertical direction, and the baffle device is located between two adjacent conveying rollers 12. The upper edge of the clamping plate 4 is not higher than the highest point of the conveying roller 12.
[0023] As can be seen from the above embodiments, the advantages of this utility model are as follows: the flush-end baffle operating structure of this solution enables the baffle to move horizontally left and right; the push-pull component is placed on the side and the weight of the baffle acts on the base component, significantly reducing the cylinder operating load; the hinged push-pull rod further optimizes the cylinder force; and with the coordinated work of the upper, middle, and lower guide wheels, it effectively improves the stability and straightness of the baffle operation, reduces shaking, reduces friction loss, and makes the baffle move smoothly, ensuring the accuracy and efficiency of flush-end operation. In terms of structural reliability, the disc springs and four rectangularly arranged disc spring buffers can effectively absorb and disperse impact forces, reduce vibration and noise, protect the baffle body and base component structure, and enhance the device's impact resistance. The reasonable design and cooperation between the components form a stable operating system, ensuring long-term stable operation of the equipment. Regarding maintenance costs, the above design greatly reduces component wear, extends the service life of each component and the overall device, reduces the frequency of equipment maintenance, and the installation window design facilitates the installation and disassembly of components such as the middle guide wheel, making later maintenance and replacement convenient and effectively saving maintenance costs. In terms of production quality, applying the end-aligning baffle device to the bar conveying line can accurately align the bars, significantly improving the bar conveying quality and processing accuracy. Furthermore, the reasonable position and height setting of the end-aligning baffle device and the conveying rollers prevents the bars from being scratched or deformed, optimizes the overall layout, and improves production efficiency and product quality.
