Description
Technical Field
[0001] This utility model relates to the field of hot-rolled strip steel shearing technology, and in particular to a hot-rolled strip steel sampling and shearing device. Background Technology
[0002] Hot-rolled strip steel refers to a narrow-width, thin-thick steel strip product formed by continuously rolling steel billets to a high temperature using multiple passes on a rolling mill. Its production process typically includes heating, rough rolling, finish rolling, cooling, and coiling. Hot-rolled strip steel is characterized by good surface quality, dense structure, and excellent plasticity and toughness, meeting the requirements for subsequent deep processing. Due to its moderate strength and good processing performance, hot-rolled strip steel is widely used in machinery manufacturing, building structures, shipbuilding, automobiles, petrochemicals, and pressure vessels, and is one of the most widely used and important basic materials in the steel industry.
[0003] To inspect the quality of hot-rolled strip steel, it is usually necessary to cut and sample the tail end of the strip before coiling. However, existing hot-rolled strip steel sampling devices lack effective limiting and clamping mechanisms on the inner side of the worktable used to place the hot-rolled strip steel. When the punching tool cuts the hot-rolled strip steel sheet at high speed, the instantaneous huge kinetic energy generated can easily cause the ends of the strip steel to shake violently or warp, affecting the stability of the sampling. At the same time, the worktable used to place the hot-rolled strip steel cannot provide the necessary limiting guidance and kinetic energy buffer for the high-speed movement of the punching tool, making the punching tool prone to deviation and shaking during the impact cutting process, resulting in insufficient cutting accuracy. Therefore, existing devices have certain limitations in use.
[0004] Based on this, we propose a hot-rolled strip sampling and shearing device to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this section is to outline some aspects of 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 the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Therefore, the purpose of this utility model is to provide a hot-rolled strip steel sampling and shearing device that can solve the problems of strip steel shaking and lifting, cutting tool deviation, and insufficient cutting accuracy caused by the lack of limiting clamping and guiding buffer mechanisms in the existing hot-rolled strip steel sampling devices during the shearing process.
[0007] To solve the above technical problems, this utility model provides a hot-rolled strip steel sampling and shearing device, which adopts the following technical solution: it includes a cutting worktable, two sets of gas-hydraulic booster cylinders are installed on the top of the cutting worktable, the output ends of the two sets of gas-hydraulic booster cylinders are connected to punching components, the punching components are located in the middle of the cutting worktable, and bidirectional limiting components are provided on the inner walls of both ends of the cutting worktable. Hot-rolled steel plates are also placed on the four sets of bidirectional limiting components and the cutting worktable. The bidirectional limiting component includes a side plate, a guide plate connected to the bottom center of the side plate, a through-hole for both positive and negative threads at one end of the guide plate, and an elastic clamping element provided on the inner side of the guide plate.
[0008] Optionally, the elastic clamping component includes two sets of first guide rods, which are slidably connected to the side plate. An anti-slip toothed plate is connected between one end of the two sets of first guide rods. The anti-slip toothed plate is located inside the side plate. A first compression spring is also sleeved in the middle of the two sets of first guide rods. The first compression spring is located between the anti-slip toothed plate and the side plate.
[0009] Optionally, the cutting worktable has limit grooves on both sides, and a baffle is slidably connected inside the limit groove. A second guide rod is connected to the bottom of the baffle. The second guide rod is slidably connected to the cutting worktable, and a second compression spring is sleeved on the outside of the second guide rod.
[0010] Optionally, a cutting slot is provided at the bottom center of the cutting workbench, and sliding grooves are provided on both sides of the cutting workbench near the cutting slot. The sliding grooves are matched with the guide plate structure, and the sliding grooves and the guide plate are in sliding fit.
[0011] Optionally, both sets of the slide grooves are internally connected to positive and negative screws via bearings. The positive and negative screws are matched with the positive and negative screw hole structures, and the positive and negative screws and the positive and negative screw holes are threadedly engaged. Both ends of the two sets of positive and negative screws are respectively equipped with transmission connectors, and an adjustment handle is also connected to the middle of the side of the transmission connector away from the positive and negative screws.
[0012] Optionally, the punching component includes a lifting base plate, both ends of which are provided with guide grooves. Limiting protrusions are installed on both sides of the inner wall of the guide grooves. The limiting protrusions match the limiting groove structure, and the limiting protrusions and limiting grooves are in sliding fit. A punching tool is also connected to the bottom center of the lifting base plate. The punching tool matches the cutting groove structure, and the punching tool and cutting groove are in insert fit.
[0013] In summary, this utility model has at least one of the following beneficial effects: 1. The hot-rolled strip steel sampling and shearing device designed in this scheme, through the adjustment and coordination of the side plate, sliding guide structure, and positive and negative screws, as well as the synergistic effect of the elastic clamping component inside the guide plate, can achieve adjustable bidirectional clamping and apply elastic downward pressure to the strip steel placed in the cutting worktable. This prevents the strip steel end from shaking and tilting, ensures the consistency and repeatability of the sampling position, and simplifies the operation process. The device can adapt to strip steel of different widths, reduce the frequency of manual adjustment, reduce sampling errors and scrap rate, and at the same time help protect the strip steel surface and reduce local deformation during the shearing process, thereby improving the representativeness and reliability of the test samples.
[0014] 2. The hot-rolled strip steel sampling and shearing device designed in this scheme provides reliable lateral guidance and impact buffering for the lifting plate and punching components through the cooperation of the limiting grooves set on both sides of the cutting worktable with the limiting protrusions on the lifting plate, and the buffering cooperation of the sliding baffle inside the limiting groove with the second guide rod and the second compression spring. This effectively prevents the lifting plate and the tool from deviating and shaking violently under high-speed punching conditions, and reduces the transmission of impact vibration to the whole machine. Through the above structural design, the cutting accuracy and repeatability accuracy can be significantly improved, the fatigue of structural components and the frequency of maintenance can be reduced, and the service life of key components can be extended. At the same time, combined with the buffer structure to absorb the impact kinetic energy, the mechanical properties of the lifting plate and the punching components can be protected, the fatigue damage of the equipment caused by long-term impact can be reduced, the long-term stable operation of the equipment can be achieved, and the safety and efficiency of the cutting operation can be improved.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: Refer to Figures 1 to 4 This utility model provides an embodiment of a hot-rolled strip steel sampling and shearing device, including a cutting workbench 1. Two sets of pneumatic-hydraulic booster cylinders 2 are installed on the top of the cutting workbench 1. The output ends of the two sets of pneumatic-hydraulic booster cylinders 2 are connected to punching components 3, which are located in the middle of the cutting workbench 1. Two bidirectional limiting components 4 are provided on the inner walls of both ends of the cutting workbench 1. Hot-rolled steel plates 5 are also placed on the four sets of bidirectional limiting components 4 and the cutting workbench 1. Each bidirectional limiting component 4 includes a side plate 6. A guide plate 7 is connected to the bottom center of the side plate 6. A positive and negative screw hole 8 is provided through the center of one end of the guide plate 7. An elastic clamping component is also provided on the inner side of the guide plate 7. 9. The sampling and shearing device, through the sliding fit between the slide groove 18 and the guide plate 7, and the threaded fit between the positive and negative screws 19 and the positive and negative screw holes 8, can provide bidirectional clamping for both sides of the hot-rolled steel plate 5 placed inside the cutting workbench 1. In conjunction with the elastic clamping member 9 installed inside the guide plate 7, which works through the cooperation of the first guide rod 10, the anti-slip toothed plate 11, and the first compression spring 12, it can also provide elastic downward pressure on the top of both sides of the hot-rolled steel plate 5 bidirectionally clamped inside the cutting workbench 1, which can prevent the hot-rolled steel plate 5 from shaking violently or warping at both ends during stamping and cutting.
[0020] The elastic clamping component 9 includes two sets of first guide rods 10, which are slidably connected to the side plate 6. An anti-slip toothed plate 11 is connected between one end of each set of first guide rods 10, and the anti-slip toothed plate 11 is located inside the side plate 6. A first compression spring 12 is also sleeved in the middle of each set of first guide rods 10, located between the anti-slip toothed plate 11 and the side plate 6. Through the cooperation of the first guide rods 10, the anti-slip toothed plate 11, and the first compression spring 12, the elastic clamping component 9 can elastically press down on the tops of both sides of the hot-rolled steel plate 5, which is bidirectionally clamped inside the cutting table 1. This prevents the hot-rolled steel plate 5 from violently shaking or warping at both ends during stamping and cutting. Limiting grooves 13 are provided on both sides of the cutting table 1. A baffle 14 is slidably connected inside the limiting groove 13. A second guide rod 15 is connected to the bottom of the baffle 14. The second guide rod 15 is connected to... The cutting worktables 1 are slidably connected. A second compression spring 16 is sleeved on the outer side of the second guide rod 15. The baffle 14, through the cooperation between the second guide rod 15 and the second compression spring 16, can limit the cutting component 3 during high-speed impact cutting. At the same time, it can also buffer the kinetic energy generated by the high-speed impact cutting of the suspended base plate 22. A cutting slot 17 is opened in the middle of the bottom of the cutting worktable 1. Slide grooves 18 are opened on both sides of the cutting worktable 1 near the cutting slot 17. The slide grooves 18 are structurally matched with the guide plate 7. The slide grooves 18 and the guide plate 7 are slidably engaged. Through the structural design of the sliding engagement between the slide grooves 18 and the guide plate 7, the guide plate 7 can be guided to move smoothly along a predetermined trajectory during the cutting process, so as to achieve accurate positioning and stable support of the hot-rolled steel plate 5 at the cutting position, and reduce the risk of shaking and deviation of the hot-rolled steel plate 5 during the cutting process.
[0021] Both sets of sliding plate grooves 18 are internally connected to positive and negative screws 19 via bearings. The positive and negative screws 19 are structurally matched with the positive and negative screw holes 8, and the positive and negative screws 19 and the positive and negative screw holes 8 are threadedly engaged. Transmission connectors 20 are installed at both ends of the two sets of positive and negative screws 19. An adjusting handle 21 is also connected to the middle of the side of the transmission connector 20 away from the positive and negative screws 19. Through the positive and negative screws 19 connected to the two sets of sliding plate grooves 18 via bearings, and the threaded engagement between the positive and negative screws 19 and the positive and negative screw holes 8, along with the transmission connectors 20 and adjusting handles 21 installed at both ends, precise adjustment and synchronous movement of the side plate 6 can be achieved. The bidirectional clamping distance can be flexibly adjusted according to the width of the hot-rolled steel plate 5, achieving stable positioning and reliable clamping of the strip steel within the cutting workbench 1, ensuring accuracy and repeatability during the cutting process. Simultaneously simplifying operation and improving work efficiency, the punching component 3 includes a lifting base plate 22. Both ends of the lifting base plate 22 are provided with guide grooves 23. Limiting protrusions 24 are installed on both sides of the inner wall of the guide grooves 23. The limiting protrusions 24 and the limiting grooves 13 are structurally matched and have a sliding fit. The bottom center of the lifting base plate 22 is also connected to a punching tool 25. The punching tool 25 and the cutting slot 17 are structurally matched and have an insertion fit. Through the structural design of the sliding fit between the limiting protrusions 24 and the limiting grooves 13, the punching component 3 can guide and limit the two ends of the lifting base plate 22, which is connected to the output end of the two sets of gas-liquid booster cylinders 2, and can prevent the lifting base plate 22 from shifting and shaking during high-speed impact cutting.
[0022] Working Principle: The hot-rolled strip steel sampling and shearing device designed in this scheme, through the sliding cooperation between the side plate 6 of the bidirectional limiting component 4 and the slide groove 18 and guide plate 7, and the threaded cooperation between the positive and negative screws 19 and the positive and negative screw holes 8, can flexibly adjust the limiting distance of the two sets of side plates 6 according to the width specification of the hot-rolled steel plate 5. It can achieve bidirectional clamping of the hot-rolled steel plate 5 placed inside the cutting workbench 1. At the same time, with the elastic clamping component 9 installed inside the guide plate 7, the elastic clamping component 9 can also apply elastic downward pressure to the top of both sides of the hot-rolled steel plate 5 bidirectionally clamped inside the cutting workbench 1 by the cooperation between the first guide rod 10, the anti-slip toothed plate 11 and the first compression spring 12. This prevents the hot-rolled steel plate 5 from shaking or warping violently at both ends during stamping and cutting, and ensures the stability of the cutting process.
[0023] The hot-rolled strip steel sampling and shearing device designed in this scheme uses limiting grooves 13 opened on both sides of the cutting workbench 1, and guide grooves 23 and limiting protrusions 24 set at both ends of the lifting plate 22. Since the limiting protrusions 24 and the limiting grooves 13 are structurally matched and have a sliding fit, they can guide and limit the two ends of the lifting plate 22, which is connected to the output end of the two sets of gas-liquid booster cylinders 2, to prevent the lifting plate 22 from deviating and shaking during high-speed impact cutting. At the same time, the baffle 14 slidably connected inside the limiting groove 13 can also limit the punching component 3 of high-speed impact cutting through the cooperation between the second guide rod 15 and the second compression spring 16, and buffer the kinetic energy generated by the high-speed impact cutting of the lifting plate 22, so as to ensure the smooth operation of the equipment cutting.
