Description

Technical Field

[0001] This invention belongs to the field of bar processing technology, and more specifically, relates to a bar finishing system and finishing method. Background Technology

[0002] Bar finishing is the core finishing process in the bar production process to ensure the quality of finished products. It takes the blank bars produced by upstream rolling and corrects the dimensional accuracy deviations of the blank bars, homogenizes the internal properties of the material, and removes surface and internal defects through a series of processes such as heat treatment, straightening, flaw detection, peeling, and packaging. Finally, it produces qualified bar products that meet industrial standards and downstream equipment manufacturing and processing requirements. Its process level directly determines the finished product quality and application level of the bars.

[0003] Currently, the production of high-quality bar stock in China generally suffers from a dispersed process layout. Multiple processes, such as heat treatment, straightening, flaw detection, and peeling, are located in different independent workshops, requiring manual transfer of semi-finished materials between these processes. This decentralized layout results in poor production continuity, long material transfer waiting times, and low overall production efficiency. Furthermore, the numerous manual handling and loading / unloading steps not only increase labor costs and intensity but also increase the risk of mixed batches and damage from impacts. Therefore, optimizing the layout of the bar stock finishing area to reduce handling frequency, improve work efficiency, and mitigate quality risks during production has become a pressing issue for the industry.

[0004] A search revealed that patent CN121019925A discloses a bar finishing zone layout structure and its process route. This application optimizes the finishing zone layout to achieve three process routes. If an alarm is triggered at any stage, the production line will not stop, reducing worker workload and improving production efficiency.

[0005] For example, patent CN116900094A discloses an intelligent finishing system and process for special steel bars. This application marks and identifies finished round steel bars, enabling each bar in the production line to be marked, identified, and tracked, achieving intelligent monitoring of production line logistics. This ensures traceability throughout the entire finishing process, prevents quality accidents caused by mixed rolling batches, and improves product control capabilities. Simultaneously, through intelligent transformation, the automation and intelligence of the production line are improved, not only enhancing production management and ensuring scientific, rational, and orderly on-site management, but also significantly reducing the large amount of heavy and tedious manual work performed by on-site personnel, increasing labor productivity, reducing labor costs, and creating a quiet, clean, and efficient working environment.

[0006] For example, patent CN117140096A discloses a finishing process route for special steel bars. This application includes four areas: a straightening and length measurement area, a length adjustment and chamfering area, a flaw detection and grinding area, and a collection and bundling area. All four areas are connected to a network. This process route can be used to create routes with and without flaw detection requirements. This application optimizes resources, achieves a high degree of automation, meets the needs of special steel products, avoids repetitive labor, improves production efficiency, and reduces labor intensity.

[0007] The aforementioned applications all involve technical improvements to the bar finishing process route, and all can effectively improve the overall efficiency of the finishing process. However, the industry still needs more diverse and sophisticated designs to address a series of shortcomings in bar finishing production caused by the dispersed layout of processes. Summary of the Invention

[0008] The problem to be solved In view of at least some of the problems existing in the prior art, the present invention proposes a bar finishing system and its finishing method, the purpose of which is to solve a series of defects caused by the dispersed process layout of the existing bar finishing production line.

[0009] Technical solution To solve the above problems, the technical solution adopted by the present invention is as follows: A bar finishing system according to the present invention includes a first storage silo and a second storage silo arranged opposite each other, with at least two production lines arranged side by side between the two silos; wherein, The two ends of multiple production lines are respectively connected to the first storage warehouse and the second storage warehouse, and the bar stock to be finished runs in opposite directions on the two adjacent production lines; The bars to be finished are transferred through two warehouses as hubs, and then processed through the corresponding production lines to complete a single process, or through two or more production lines to complete multiple processes in sequence.

[0010] In some embodiments, the production line includes a heat treatment line, a black leather finishing line, and a silver finishing line; wherein, The heat treatment line includes a heat treatment conveyor line connecting two storage chambers, and a heat treatment furnace is installed on the heat treatment conveyor line; the running direction of the bars to be finished on the heat treatment conveyor line is from the first storage chamber to the second storage chamber.

[0011] In some embodiments, the black leather finishing line includes a black leather conveyor line connecting two warehouses; wherein, The black conveyor line, along the direction from the second storage warehouse to the first storage warehouse, is sequentially equipped with a first straightening machine, a first chamfering machine, and a first flaw detector; The direction of travel of the bars to be finished on the black conveyor line is opposite to that on the heat treatment conveyor line.

[0012] In some embodiments, a first dust collector is provided between the first straightening machine and the first chamfering machine.

[0013] In some embodiments, the silver-bright finishing line includes a silver-bright conveyor line connecting two warehouses; wherein, The silver-bright conveyor line is equipped with a peeling machine, a second straightening machine, and a second flaw detector in sequence from the first storage warehouse to the second storage warehouse. The running direction of the bars to be finished on the bright silver conveyor line is the same as that on the heat treatment conveyor line.

[0017] As described above, the finishing method of a bar finishing system includes single-process finishing and multi-process finishing, depending on production requirements. The multi-process finishing includes two-process finishing and three-process finishing. The single-process finishing steps are as follows: After the finished bar stock is processed through one of the heat treatment lines, black skin finishing lines, or silver bright finishing lines from one of the silos, it enters another silo. The steps of the dual-process finishing are as follows: The finished bar stock is processed by the heat treatment line from the first storage warehouse and then transferred to the second storage warehouse.

[0023] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0024] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] like Figure 1 As shown, a bar finishing system according to this embodiment includes a first storage silo 100 and a second storage silo 200 arranged opposite to each other, and multiple production lines (at least two) arranged side by side between the two silos. The two ends of the multiple production lines are respectively connected to the first storage silo 100 and the second storage silo 200, and the bars to be finished run in opposite directions on adjacent production lines.

[0027] During operation, the bars to be finished are transferred through two warehouses as hubs, and then processed through the corresponding production lines to complete a single process, or through two or more production lines to complete multiple processes in succession.

[0028] This embodiment of a bar finishing system arranges multiple production lines in parallel between a first storage silo 100 and a second storage silo 200, using the two storage silos as a transfer and scheduling hub. This achieves a compact and reasonable layout of multiple production lines, ensuring that each production line can complete processing independently and operate without interference. Furthermore, by scheduling the storage, a cyclical multi-process continuous processing path can be formed, effectively shortening the material transfer distance in the multi-process processing and significantly improving the overall processing efficiency of bar finishing.

[0029] In one specific embodiment of this invention, three production lines are arranged between the two storage warehouses: a heat treatment line 300, a black leather finishing line 400, and a silver finishing line 500. The black leather finishing line 400 is located between the heat treatment line 300 and the silver finishing line 500.

[0030] Specifically, the heat treatment line 300 includes a heat treatment conveyor line 310 connecting two storage silos, and a heat treatment furnace 320 is provided on the heat treatment conveyor line 310. The running direction of the bars to be finished on the heat treatment conveyor line 310 is from the first storage silo 100 to the second storage silo 200.

[0031] The black leather finishing line 400 includes a black leather conveyor line 410 connecting two warehouses. Along the direction from the second warehouse 200 to the first warehouse 100, the black leather conveyor line 410 is sequentially equipped with a first straightening machine 420, a first chamfering machine 430, and a first flaw detector 440.

[0032] Meanwhile, the running direction of the bar stock to be finished on the black finishing line 400 is opposite to the running direction on the heat treatment conveyor line 310. That is, the bar stock to be finished moves along the direction from the second storage silo 200 to the first storage silo 100 on the black conveyor line 410.

[0033] The silver bright finishing line 500 includes a silver bright conveyor line 510 connecting two warehouses. The silver bright conveyor line 510 is provided with a peeling machine 520, a second straightening machine 530 and a second flaw detector 540 in sequence from the first warehouse 100 to the second warehouse 200.

[0034] Meanwhile, the bar stock to be finished moves in the same direction on the bright finishing line 500 as it moves on the heat treatment conveyor line 310. That is, the bar stock to be finished moves along the direction from the first storage silo 100 to the second storage silo 200 on the bright conveyor line 510.

[0035] In some embodiments, a first dust collector 450 is provided between the first straightening machine 420 and the first chamfering machine 430 to remove oxide scale and debris adhering to the surface of the bar, so as to avoid impurities affecting the subsequent processing accuracy.

[0036] Meanwhile, a second chamfering machine 550 is provided between the second flaw detector 540 and the second storage warehouse 200 to chamfer the bar after silvering, so as to avoid sharp edges and burrs at the ends of the bar, and further ensure the quality of the product.

[0037] Furthermore, in this embodiment, the first storage unit 100 is also connected to a first conveyor line 110, and the second storage unit 200 is also connected to a second conveyor line 210, and the number of the first conveyor line 110 and the second conveyor line 210 are the same as the number of production lines.

[0038] Specifically, in this embodiment, the first conveyor line 110 and the second conveyor line 210 are each provided with three lines, corresponding to the heat treatment line 300, the black leather finishing line 400 and the silver bright finishing line 500, respectively, so as to effectively reduce the time for raw material input and finished product output, thereby further improving work efficiency.

[0039] Meanwhile, in this embodiment, the heat treatment conveyor line 310, the black skin conveyor line 410, the silver bright conveyor line 510, the second conveyor line 210 and the first conveyor line 110 can all adopt existing technologies, such as roller conveyor lines, etc., and are not specifically limited here.

[0040] In addition, it is worth mentioning that in this embodiment, the first storage warehouse 100 and the second storage warehouse 200 have the same structure and are both intelligent warehouses (existing technology), which can realize the tracking of bundled bars, automatic feeding and automatic discharging, and automatically allocate the storage location of bars according to production and warehouse storage conditions, and store and retrieve specified bundled bars according to production needs.

[0041] This embodiment also provides a bar finishing method. Depending on production requirements, the finishing method includes single-process finishing and multi-process finishing, with multi-process finishing including two-process finishing and three-process finishing. Specifically, The steps for single-process finishing are as follows: Single heat treatment finishing: The bar stock to be finished enters the first storage silo 100 from the first conveyor line 110 corresponding to the heat treatment line 300, and after being processed by the heat treatment line 300, it enters the second storage silo 200, and is finally output by the second conveyor line 210 corresponding to the heat treatment line 300.

[0042] Single black bar finishing: The bar to be finished enters the second storage warehouse 200 from the second conveyor line 210 corresponding to the black bar finishing line 400, and after being processed by the black bar finishing line 400, it enters the first storage warehouse 100, and is finally output by the first conveyor line 110 corresponding to the black bar finishing line 400.

[0043] The entire process of single silver bright finishing is basically the same as that of single heat treatment finishing, except that single silver bright finishing is completed through silver bright finishing line 500.

[0044] The steps for dual-process finishing are as follows: Heat treatment and black finishing: The finished bars are processed from the first storage silo 100 through the heat treatment line 300 and then transferred to the second storage silo 200. They are then processed from the second storage silo 200 through the black finishing line 400 and then returned to the first storage silo 100, and finally output from the first storage silo 100.

[0045] The black-skinned and silver-brightened finished bar stock is processed from the second storage warehouse 200 via the black-skinned finishing line 400 and then transferred into the first storage warehouse 100. After being processed from the first storage warehouse 100 via the silver-brightening finishing line 500, it enters the second storage warehouse 200 and is finally output from the second storage warehouse 200.

[0046] The three-stage finishing process is as follows: The finished bar stock is processed from the first storage silo 100 via the heat treatment line 300 and then transferred to the second storage silo 200. It is then processed from the second storage silo 200 via the black finishing line 400 and then transferred back to the first storage silo 100. Finally, it is processed from the first storage silo 100 via the silver finishing line 500 and then transferred back to the second storage silo 200, where it is finally output.

[0047] That is, at this time, the raw materials complete the entire process of finishing by following the path of the first storage silo 100, heat treatment line 300, second storage silo 200, black leather finishing line 400, first storage silo 100, silver finishing line 500, and second storage silo 200. The heat treatment finishing, black leather finishing, and silver finishing are carried out in one go, and the final finished product is output from the second storage silo 200.

[0048] This embodiment of a bar finishing method allows for flexible selection of single-process, double-process, triple-process, and more-process finishing paths based on actual production needs. Each process relies on dual storage facilities for transfer and scheduling, eliminating the need for long-distance cross-regional transport. This ensures that each process operates independently, and the suspension or failure of one process will not affect the normal processing of other processes, avoiding production stoppages caused by a complete shutdown. Furthermore, it enables continuous cyclical processing of multiple processes, effectively shortening the bar transfer route, reducing transport time, and lowering the risk of collision damage during transport, thereby further improving the overall efficiency and product quality of bar finishing.

[0049] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
