Description

Technical Field

[0001] This invention relates to the field of flying shear devices, and in particular to a fixed-length flying shear device for a high-speed leveling line. Background Technology

[0002] In high-speed sizing lines, the fixed-length flying shear device is the core component for achieving precise fixed-length cutting of sheet metal. Its cutting accuracy, adaptability, and operational stability directly determine the production efficiency and finished product quality of the sizing line. In existing technologies, conventional high-speed sizing line fixed-length flying shear devices are only equipped with a single cutting execution structure. This structure is fixedly connected to the base, which not only makes it impossible to adjust the cutting angle according to cutting needs, but also results in poor flexibility in adjusting the spacing of the cutters, making it difficult to adapt to cutting operations of sheet metal of different thicknesses.

[0003] Meanwhile, the device lacks an effective tensioning and limiting structure in the plate conveying path, which can easily lead to deviation and slack during plate conveying, resulting in a significant decrease in the positioning accuracy of the flying shear during cutting, and causing cutting size deviation and uneven cutting surface.

[0004] In addition, traditional flying shear devices have no buffer or shock absorption design for the cutter blade. During the cutting process, the impact force acts directly on the cutter blade and transmission components, which can easily cause the cutter blade to wear out too quickly and the transmission structure to loosen, further reducing the cutting accuracy and service life of the device.

[0005] In the existing flying shear device, the sliding adjustment structure of the cutting component on the base is simple and cannot achieve multi-dimensional position and angle adjustment. The tensioning component only uses a fixed conveying roller shaft, which cannot adjust the tension force and limit range in real time according to the width and thickness of the board. The low degree of cooperation with the flying cutting component results in poor stability of the board during high-speed conveying and cutting. It is difficult to meet the high-efficiency and precise length cutting requirements of high-speed leveling lines for different specifications of boards, which restricts the operating efficiency and finished product qualification rate of the leveling line.

[0013] Preferably, a symmetrical first slide is slidably installed inside the first groove. A first mounting plate is fixedly installed on the upper ends of the two first slides laterally. A limiting conveying assembly is provided on the upper part of the two first mounting plates. The limiting conveying assembly includes a first upright plate.

Symmetrical through holes are opened from the outer side to the inner side of the first upright plate. A grooved wheel is rotatably installed on the inner side of the first upright plate and outside the through hole. A track is rotatably installed on the circumference of the grooved wheel. The other end of the track is rotatably connected to a first motor. The first motor is fixedly installed on the outer side of the first upright plate.

[0014] Preferably, a first telescopic pump is fixedly installed on the upper inner side of the first upright plate.

A limiting connection hole is opened from the inner side of the limiting plate to the inside of the first connecting rod. A second connecting rod is slidably installed inside the two limiting connection holes. An intermediate plate is fixedly installed inside the adjacent ends of the two second connecting rods.

[0015] Preferably, the inner side of the second upright plate is provided with a third protrusion at both the upper and lower ends. A symmetrical double-headed telescopic pump is fixedly installed in the middle of the inner side of the two second upright plates. A triangular rod is rotatably installed on the telescopic rods at both ends of the upper and lower double-headed telescopic pumps. A second slide is rotatably installed on the outer side of the far end of the upper and lower triangular rods. The second slide is slidably installed inside the adjacent third protrusion.

[0016] Preferably, an air shaft is provided between the lower ends of the two front and rear triangular rods, and a conveying shaft is rotatably installed on the inner side of one corner of the two front and rear triangular rods near the second slide table. Symmetrical telescopic adjustment rods are slidably installed on the outer sides of the two adjacent air shafts and conveying shafts.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features two sliding connecting slides on the upper right side of the base, with a rectangular frame equipped with symmetrical cutters rotatably mounted on its upper end. Adjustable hydraulic rods are fitted to the outer side of the rectangular frame. A tensioning assembly with an air shaft and a conveying shaft is located in the middle of the base. This solves the problems of fixed cutting components, poor cutter adjustability, and easy deviation and loosening of the conveyed sheet material in traditional devices. The connecting slides and adjusting hydraulic rods allow for cutter sliding and angle adjustment, adapting to various cutting methods. The cutter spacing can be flexibly adjusted, and the tensioning assembly can stably tension and convey the sheet material, improving the accuracy of the flying shear from both cutting and conveying perspectives, and meeting the needs of high-speed leveling lines.

[0018] 2. This invention features a first mounting plate with a first sliding platform on the left side of the base, paired with a limiting conveying assembly including a limiting plate and a first telescopic pump. This solves the problem of poor conveying stability for plates of different materials and widths due to the lack of adaptable limiting structures. The first sliding platform allows for adjustable component positions, and the first telescopic pump can adjust the spacing of the limiting plates to adapt to plates of different widths. It also allows switching conveying modes. Soft plates are conveyed by the auxiliary conveying assembly in conjunction with limiting, while hard plates are clamped and conveyed by the limiting plates, preventing plate wrinkling and displacement, providing precise positioning for cutting, and forming a coordinated conveying and limiting system with the tensioning assembly.

[0019] 3. This invention features a movable plate with forward and reverse motor linkage within a rectangular frame. A shock-absorbing spring is installed between the movable plate and the cutter mounting plate. The tensioning assembly is equipped with a double-headed telescopic pump-driven air shaft, conveying shaft, and telescopic adjustment rod. This solves the problems of low cutter adjustment precision, easy wear, and the inability of the tensioning assembly to adapt to different specifications of sheet metal. The forward and reverse motors enable precise adjustment of the cutter spacing, the shock-absorbing springs absorb cutting impact, reduce wear, and improve the flatness of the cut surface. The tensioning assembly allows for real-time adjustment of the tension, and the telescopic adjustment rod adapts to different widths of sheet metal, significantly improving the adaptability and stability of the device and meeting the requirements for long-term continuous operation.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 8 The present invention provides a technical solution: A high-speed leveling line fixed-length flying shear device includes a base 1, with symmetrical first protrusions 101 formed on the upper left side of the base 1, and an auxiliary conveying assembly 102 fixedly installed on the upper left side of the base 1 above the two first protrusions 101. Figure 2 As shown.

[0025] Both the front and rear ends of the two first protrusions 101 on the left and right sides are slidably mounted with first slides 201, and the tops of the two first slides 201 on the sides are fixedly mounted with a first mounting plate 2. Figure 3 As shown.

[0026] Limiting conveying components 3 are provided on the upper surfaces of the two first mounting plates 2. The limiting conveying components 3 include four first upright plates 301, which are arranged in pairs and fixedly installed on the upper surfaces of the first mounting plates 2 by bolts.

[0027] The upper outer and inner sides of the first upright plate 301 are provided with symmetrical through holes 302. A grooved wheel 303 is rotatably mounted on the inner side of the first upright plate 301, outside the through holes 302. A gear 304 is fixedly mounted on the outer circumferential surface of one end of the grooved wheel 303, with adjacent gears 304 meshing with each other. Furthermore, tracks 311 are rotatably mounted on the outer circumferential surfaces of the two lower grooved wheels 303. A first motor 310 is rotatably mounted on the inner other end of the two tracks 311. Both the front and rear first motors 310 are fixedly mounted on the outer side of the first upright plate 301. Figure 3 As shown.

[0028] In addition, a first telescopic pump 312 is fixedly installed on the upper inner side of the first upright plate 301. A moving rod 313 is fixedly installed on the telescopic rod of the first telescopic pump 312. Two symmetrical first connecting rods 305 are rotatably installed on the inner side of the moving rod 313 (it should be noted that the structure of the first connecting rod 305 is a cylinder, and two protruding rods protrude outward on the circumference of the cylinder for subsequent sliding connection with the structure, and to rotate synchronously with the subsequent structure). One end of the inner side of the first connecting rod 305 passes through the through hole 302 and the grooved rotating wheel 303. The grooved rotating wheel 303 and the first connecting rod 305 are structurally matched. Therefore, the grooved rotating wheel 303 can rotate synchronously with the first connecting rod 305. Furthermore, a circular limiting plate 306 is fixedly installed on one end of the inner side of each first connecting rod 305. A limiting connection hole 307 is opened on the inner side of the limiting plate 306 to the inside of the first connecting rod 305. Figure 4 As shown.

[0029] A matching first connecting rod 305 is slidably installed from the inside to the outside of the limiting connection hole 307, and an intermediate plate 309 is fixedly installed between two adjacent first connecting rods 305. Figure 4As shown, it should be noted that in order to prevent the two limiting plates 306 from moving outward at different distances, a telescopic device can be provided between the inner side of the two limiting plates 306 and the outer side of the middle plate 309, depending on the actual situation. It should be noted that the two sides of the middle plate 309 are fixedly installed with the second connecting rod 308, and the second connecting rod 308 is slidably installed into the interior of the corresponding limiting connecting hole 307.

[0030] It should be noted that the limiting conveyor component 3 is divided into two halves: one half for conveying and the other half for limiting. Figure 1 As shown, the left half of the limiting conveying component 3 works with the auxiliary conveying assembly 102 to convey the raw materials, while the right half works with the limiting plate 306 to limit the forward and backward movement of the raw materials, so as to prevent the raw materials from deviating.

[0031] Secondly, when dealing with harder materials, the upper and lower limit plates 306 can be used for conveying throughout the process, while the auxiliary conveying assembly 102 is used to convey softer materials, thereby increasing the versatility of the conveying device and enabling it to adapt to different materials.

[0032] Therefore, with the above structure, during use, the device can be used according to the specific situation for materials of different hardness, and efficient conveying can be achieved by activating the corresponding drive component.

[0033] When processing soft raw materials, the auxiliary conveying assembly 102 and the conveying mechanism on the left side of the limiting conveying component 3 are activated. The raw material moves forward under the drive of the auxiliary conveying assembly 102. At the same time, the front and rear limiting plates 306 on the left side of the limiting conveying component 3 perform conveying operations, while the front and rear limiting plates 306 on the right side limit the front and rear edges of the raw material to prevent the raw material from deviating and ensure that the soft raw material does not wrinkle or deform.

[0034] If processing hard raw materials, the material is allowed to pass between the upper and lower limit plates 306.

[0035] Secondly, when dealing with raw materials of different widths, the first telescopic pump 312 is activated, which pushes the moving rod 313 to move the first connecting rod 305 and the limiting plate 306 inward, thereby changing the distance between the two limiting plates 306 and thus limiting the front and rear sides of the passing raw material.

[0036] Through the above-described operation process, the clamping, conveying, and front-to-back limiting of hard raw materials are achieved. This switchable conveying mode not only improves the adaptability of the device but also effectively ensures the stability of raw materials of different materials during the conveying process, providing accurate material positioning for the subsequent fixed-length flying shear process and significantly improving the working efficiency and cutting accuracy of the flying shear device.

[0037] A tensioning component 4 is provided on the upper middle part of the base 1. The tensioning component 4 includes two second upright plates 401. The upper and lower ends of the inner sides of the two second upright plates 401 are provided with third protrusions 402. Furthermore, a symmetrical double-headed telescopic pump 403 is fixedly installed on the inner side. A triangular rod 404 is rotatably installed on the telescopic rods at both ends of the double-headed telescopic pump 403. A second slide table 405 is rotatably connected to one corner of the triangular rod 404 away from the double-headed telescopic pump 403. It should be noted that the position where the second slide table 405 is rotatably connected is that both rods are rotatably connected to the second slide table 405 at the same time, rather than a corner of a fixed entity being rotatably connected to the second slide table 405.

[0038] Secondly, an air shaft 406 is rotatably mounted between the two adjacent ends of the upper and lower triangular rods 404 and the two corners at the same height. A conveyor shaft 407 is rotatably mounted on the inner side of the corner where the two triangular rods 404 and the second slide 405 are rotatably connected. Figure 6 As shown. Then, telescopic adjusting rods 408 are slidably installed at both ends of the two air expansion shafts 406 and the conveying shaft 407 to limit the movement of the raw materials on both sides.

[0039] It should be noted that at the sliding connection point between the telescopic adjusting rod 408 and the air shaft 406, an air bladder is installed on the inner side of the telescopic adjusting rod 408 to ensure a tight fit with the air shaft 406 without affecting the outward expansion operation of the air shaft 406.

[0040] Therefore, during use, the telescopic adjustment rod 408 can be slid to the corresponding position according to the width of the raw material to be processed. Its inner air bladder is tightly fitted with the air expansion shaft 406 to ensure that the limit is stable and does not interfere with the subsequent tensioning action.

[0041] Then the double-headed telescopic pump 403 is started, and its two telescopic rods extend and retract synchronously, driving the triangular rod 404 to adjust the angle, thereby expanding and relaxing the raw material passing through.

[0042] The synchronous conveying of the air expansion shaft 406 and the conveying shaft 407 can handle the conveying of different raw materials. This is because, during use, when the width of the raw material changes, the pre-adjusted telescopic adjustment rod 408 can accurately limit the movement of both sides of the raw material.

[0043] Meanwhile, the air shaft 406 can expand or contract according to the thickness or tension requirements of the raw material, while the conveying shaft 407 provides stable rotational power. The two work together to adapt to the conveying requirements of raw materials of different specifications (such as width and thickness), ensuring that the raw material remains stable and does not deviate during the conveying process. This effectively avoids conveying jams or positional deviations caused by differences in raw material specifications, providing stable preconditions for subsequent fixed-length flying shear operations.

[0044] Then, two second protrusions 105 are formed on the upper right side of the base 1, and the connecting slide 518 of the flying cutter assembly 5 is slidably installed inside the second protrusions 105, such as... Figure 8 As shown.

[0045] Secondly, L-shaped mounting plates 501 are fixedly installed on both the front and rear sides of the right side of the base 1. A fourth protrusion 502 is opened in the middle of the inner side of the two L-shaped mounting plates 501. A second motor 503 is fixedly installed in the middle of the right side. The output shaft of the second motor 503 extends into the interior of the fourth protrusion 502. A threaded rod 504 is fixedly installed on the output shaft of the second motor 503. A third slide 505 is rotatably installed on the circumferential surface of the threaded rod 504. An adjusting hydraulic rod 506 is rotatably installed on one outer end of the third slide 505. A rectangular frame 507 is rotatably installed on the inner side of the two adjusting hydraulic rods 506. The lower end of the rectangular frame 507 and the top of the connecting slide 518 are rotatably connected by a hinge.

[0046] A forward and reverse motor 508 is fixedly installed at the front and rear of the inner center of the rectangular frame 507. A first connecting plate 509 is fixedly installed on the output shaft of each of the forward and reverse motors 508. Adjusting plates 510 facing opposite directions are rotatably installed at both ends of the first connecting plate 509. An adjusting rod 511 is threadedly rotatably installed at the end of the adjusting plate 510 away from the first connecting plate 509. Another adjusting plate 510 is rotatably installed at the other end of the adjusting rod 511. Figure 8 As shown.

[0047] A movable plate 512 is rotatably mounted between the two adjusting plates 510 at the bottom and top. Shock-absorbing springs 513 are fixedly mounted at both ends of the adjacent sides of the two movable plates 512. Mounting plates 514 are fixedly mounted at the ends of the two left and right shock-absorbing springs 513 away from the movable plates 512. Mounting grooves 515 are fixedly mounted on the adjacent sides of the two mounting plates 514, and cutters 516 are slidably mounted on the inner sides of the two mounting grooves 515. Figure 8 As shown.

[0048] Two round rods 517 are fixedly installed on the inner side of the rectangular frame 507. The round rods 517 are slidably connected to the movable plate 512, the shock-absorbing spring 513, and the mounting plate 514, as shown below. Figure 8 As shown.

[0049] With the above structure, during use, the second motor 503 is first started, and its output shaft drives the threaded rod 504 to rotate, causing the third slide 505 to slide along the fourth convex groove 502, which drives the adjusting hydraulic rod 506 and the rectangular frame 507 to adjust the direction, for oblique flying cut and tilt flying cut of raw materials.

[0050] Start the forward and reverse motor 508, whose output shaft drives the first connecting plate 509 to rotate. Through the linkage of the adjusting plate 510 and the adjusting rod 511, the upper and lower moving plates 512 are driven to slide in opposite directions along the round rod 517 until the spacing between the upper and lower cutting blades 516 matches the thickness of the material to be cut.

[0051] At this time, when the board material conveyed by the high-speed leveling line reaches the predetermined length position, the flying cutter assembly 5 moves quickly, and the upper and lower cutters 516 precisely engage under the buffering effect of the shock-absorbing spring 513 to complete the length cutting of the board material.

[0052] During the cutting process, the shock-absorbing spring 513 can effectively absorb the cutting impact, reduce the wear of the cutter 516 and improve the flatness of the cut surface. After the cutting is completed, the second motor 503 and the forward and reverse motors 508 are reset and wait for the next cutting command. The whole process is highly automated and the cutting accuracy is stable, which can meet the high-speed leveling line's demand for efficient fixed-length flying shear for different specifications of plates.

[0053] It should be noted that the shock-absorbing spring component 513 adopts a double-helix composite structure made of high-elasticity alloy steel wire. This structure has excellent fatigue resistance and high recovery force, and can maintain a stable buffering effect under high-frequency cutting impact.

[0054] Meanwhile, its surface is treated with zinc plating and passivation, which can effectively resist rust in humid environments, significantly extend the service life of components, and fully adapt to the harsh working conditions of long-term continuous operation of high-speed leveling lines.

[0055] In addition, wear-resistant rubber pads are provided at both ends of the shock-absorbing spring 513, which further enhances the shock absorption effect during buffer contact and avoids damage to the cutter 516 and the spring itself caused by hard contact.

[0056] Finally, the base 1 has a first support rod 103 fixedly installed on the front and rear sides of the middle part, and auxiliary rollers 104 in a symmetrical state are rotatably installed on the upper inner side of the two first support rods 103, so that the raw material can pass between the upper and lower auxiliary rollers 104.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
