It can shear out thin plate raw materials of automotive parts that meet the design standards at high speed and high precision, and supply them to the next stamping process.

[0003] After searching, the patent document with publication number CN219464895U discloses a steel coil shearing device, which includes a mounting frame and a shearing platform on one side of the mounting frame, the mounting frame is rotatably connected to a leveling roller, the shearing platform is provided with a fixed frame, a first knife groove and a second knife groove, the fixed frame is provided with a hydraulic cylinder and a connecting frame, the hydraulic cylinder is connected to a mounting plate, a horizontal shearing knife is fixedly provided on the mounting plate and a vertical shearing knife is movably provided, the horizontal shearing knife and the vertical shearing knife are respectively matched with the first knife groove and the second knife groove, the vertical shearing knife is provided with an electromagnetic plate, the connecting frame is provided with a cylinder, and the cylinder is connected to a collection box.

[0017] The beneficial effects of the present invention are as follows: 1. In the present invention, the output shaft of the first motor drives the threaded rod to rotate. Under the limitation of the two sliding rods, the first mounting plate drives the loading roller to slide under the bottom of the top plate until the loading roller is inserted into the inner cavity of the second groove. Then, the two loading rollers support the steel coil. By pulling the first mounting plate through the first slider, the pressure on the sliding rod and the threaded rod can be reduced, avoiding the steel coil from bending the sliding rod and the threaded rod. Then, one end of the steel coil is passed through the bottom of the limiting roller. The limiting roller presses the steel coil to prevent the steel coil from tilting too high during rotation. The output shaft of the second motor drives the bidirectional threaded rod to rotate. Under the limitation of the fourth groove, the two clamping plates approach each other to limit the steel coil, preventing the steel coil from skewing during transportation.

[0018] 2. In the present invention, the output end of the electric telescopic rod drives the third slider to extend, which can adjust the height of the matching roller, and further achieve the purpose of adjusting the distance between the matching roller and the material conveying roller. This can clamp the steel coil between the matching roller and the material conveying roller, avoiding slipping between the material conveying roller and the steel coil when the material conveying roller rotates. During use, the output shaft of the third motor drives the material conveying roller to rotate to convey the steel coil. When the material conveying roller rotates, the material conveying roller drives the third pulley to rotate through the connecting shaft. After being driven by the second belt, the second pulley also starts to rotate. The second pulley drives the transmission rod to rotate, the transmission rod drives the first pulley to rotate, and the first pulley further drives the steel coil to rotate, making it easier to pull the steel coil.

[0019] 3. In the present invention, the output shaft of the fourth motor drives the fourth pulley to rotate. Through the third belt drive, the fourth pulley drives the incomplete gear to rotate. The incomplete gear can drive the rack to move downward, and the rack drives the cutter to move downward to shear the steel coil. After the shearing is completed, the incomplete gear is briefly disengaged from the rack. At this time, the second spring rod extends to move the cutter away from the steel coil. After the steel coil is sheared, the discharge roller rotates to move the sheared steel coil away from the second mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 7 As shown, a steel coil flying shear includes a bracket 1. Two loading rollers 222 are rotatably installed in the inner cavity of the bracket 1. A second mounting plate 3 is fixedly installed on the top of the bracket 1. It further includes a pushing mechanism for pushing the sheared steel coil away from the flying shear. The pushing mechanism includes two support plates 34. The two support plates 34 are fixedly installed on the top of the second mounting plate 3. A cutter 342 is slidably installed on the common opposite surfaces of the two support plates 34. Two racks 343 are fixedly installed at the bottom of the cutter 342. The racks 343 are engaged with an incomplete gear 36. A discharging roller 364 is rotatably installed on the opposite surfaces of the two support plates 34. Fourth pulleys 362 are fixedly connected to one side of the discharging roller 364 and the incomplete gear 36. The two fourth pulleys 362 are driven by a third belt 363. A fourth motor 37 is fixedly connected to one side of one of the fourth pulleys 362. The fourth motor 37 is fixedly installed on one side of the support plate 34. Two second spring rods 35 are fixedly connected to the bottom of the cutter 342. The second spring rods 35 are fixedly installed on the outer surface of the second mounting plate 3. On one side of the support plate 34, a seventh groove 341 is provided. The cutting knife 342 is slidably installed on the inner surface of the seventh groove 341. On the opposite surfaces of the two incomplete gears 36, a transmission shaft 361 is fixedly connected. The rack 343 is slidably installed on one side of the support plate 34. On one side of the rack 343, an eighth groove 3431 is provided. A T-shaped block 3432 is slidably installed on the inner surface of the eighth groove 3431, and the T-shaped block 3432 is fixedly installed on one side of the support plate 34.

[0025] In the existing flying shear, after the steel coil is sheared, the steel coil falls by gravity, lacking a structure to push out the steel coil. Allowing the steel coil to fall by gravity easily causes the steel coil to accumulate at the discharge port, affecting subsequent discharging.

[0026] When the present invention is in use, first, the steel coil is placed on the outer surfaces of the two loading rollers 222. Then, the steel coil passes through the bottom of the cutting knife 342. At this time, the output shaft of the fourth motor 37 drives the fourth pulley 362 to rotate. Through the transmission of the third belt 363, the other fourth pulley 362 drives the incomplete gear 36 to rotate. Through the transmission of the transmission shaft 361, both incomplete gears 36 start to rotate. When the incomplete gear 36 rotates, it meshes with the rack 343 and can drive the rack 343 to move downward. At this time, the T-shaped block 3432 slides on the inner surface of the eighth groove 3431 to limit the rack 343. At the same time, the rack 343 drives the cutting knife 342 to move downward to shear the steel coil. At this time, the cutting knife 342 presses the second spring rod 35 downward. After the shearing is completed, the incomplete gear 36 no longer meshes with the rack 343. At this time, the second spring rod 35 extends and drives the cutting knife 342 to move upward. When the steel coil is sheared, the other end of the steel coil is fixed. Therefore, at this time, the discharging roller 364 rotates and cannot pull the steel coil. After the steel coil is cut off, the fourth pulley 362 drives the discharging roller 364 to rotate, enabling the sheared steel coil to move away from the second mounting plate 3.

[0027] Further, as Figure 3 shown, a top plate 2 is fixedly installed on the top of the bracket 1. A third groove 201 is provided on the bottom of the top plate 2. A first slider 202 is slidably installed on the inner surface of the third groove 201. The bottom of the first slider 202 is fixedly connected to a first mounting plate 21; Two slide rods 24 are fixedly installed on the inner surface of the top plate 2. A threaded rod 241 is rotatably installed on the inner surface of the top plate 2. The two slide rods 24 are slidably connected to the first mounting plate 21. The threaded rod 241 is threadedly connected to the first mounting plate 21, and one end of the threaded rod 241 is fixedly connected to a first motor 242. The first motor 242 is fixedly installed on one side of the bracket 1.

[0028] When the present invention is in use, when conveying a steel coil, the steel coil is first placed between the first mounting plate 21 and the inner wall of the bracket 1. Then, the output shaft of the first motor 242 drives the threaded rod 241 to rotate. Under the limitation of the two slide rods 24, the first mounting plate 21 drives the loading roller 222 to pass through the center of the steel coil and insert into the inner surface of the two second grooves 12. Then, the two loading rollers 222 support the steel coil. Since the mass of the steel coil is relatively large, in order to prevent the threaded rod 241 and the slide rod 24 from being bent by the steel coil during use, the first mounting plate 21 is pulled by the first slider 202 to further increase the supporting force of the first mounting plate 21.

[0029] Further, as Figure 2 and Figure 6 shown, the inner surface of the bracket 1 is provided with a first groove 11 and two second grooves 12. Two first pulleys 22 are rotatably mounted on one side of the first mounting plate 21. The two first pulleys 22 are driven by a first belt 221. The loading roller 222 is fixedly mounted on one side of the first belt 221. One end of the loading roller 222 is slidably mounted on the inner surface of the second groove 12. One side of one of the first pulleys 22 is fixedly connected to a transmission rod 23. A limiting rod 231 is fixedly mounted on the outer surface of the transmission rod 23; A support frame 33 is fixedly mounted on the top of the second mounting plate 3. A material conveying roller 331 is rotatably mounted in the inner cavity of the support frame 33. One side of the support frame 33 is fixedly connected to a third motor 332. The output shaft of the third motor 332 is fixedly mounted on one side of the material conveying roller 331; One side of the material conveying roller 331 is fixedly mounted with a connecting shaft 333. One side of the bracket 1 is rotatably mounted with a second pulley 334. A limiting groove 3341 is provided on one side of the second pulley 334. The transmission rod 23 and the limiting rod 231 are slidably mounted on the inner surface of the limiting groove 3341. One end of the connecting shaft 333 is fixedly connected to a third pulley 336. The third pulley 336 and the second pulley 334 are driven by a second belt 335.

[0030] When the present invention is in use, the steel coil is at the bottom of the material conveying roller 331. The output shaft of the third motor 332 drives the material conveying roller 331 to rotate to convey the steel coil. The material conveying roller 331 drives the connecting shaft 333 to rotate. The connecting shaft 333 further drives the third pulley 336 to rotate. Through the transmission of the second belt 335, the second pulley 334 also starts to rotate. The second pulley 334 drives the transmission rod 23 and the limiting rod 231 to rotate together. The transmission rod 23 further drives the first pulley 22 to rotate. Through the transmission of the first belt 221, the two first pulleys 22 respectively drive the two loading rollers 222 to rotate, thereby realizing the rotation of the steel coil to convey the steel coil; When the first mounting plate 21 slides along the top plate 2, the transmission rod 23 and the limiting rod 231 slide on the inner surface of the limiting groove 3341. By limiting the transmission rod 23 with the limiting rod 231, it is possible to prevent the second pulley 334 from slipping when driving the transmission rod 23 to rotate.

[0031] Furthermore, as Figure 4 shown, a mounting frame 4 is fixedly installed at the top of the bracket 1. Two first spring rods 41 are fixedly installed in the inner cavity of the mounting frame 4. The output ends of the first spring rods 41 are fixedly connected with second sliders 42. The second sliders 42 are slidably installed in the inner cavity of the mounting frame 4. A limiting roller 43 is rotatably connected to the opposite surfaces of the two second sliders 42.

[0032] When the present invention is in use, in order to prevent the part of the steel coil that is separated from the overall steel coil from warping too high, the steel coil is made to pass under the limiting roller 43 during use. At this time, since the flying shear pulls the steel coil, the steel coil will lift the limiting roller 43. The limiting roller 43 drives the second slider 42 to slide on the inner surface of the first spring rod 41. At this time, the two first spring rods 41 jointly support the second slider 42 to prevent the limiting roller 43 from having too large a movement range and losing the binding effect on the steel coil.

[0033] Furthermore, as Figure 4 shown, a fourth groove 31 and a fifth groove 32 are formed in the top of the second mounting plate 3. Two clamping plates 311 are slidably installed on the inner surface of the fourth groove 31. A second motor 313 is fixedly installed on one side of the second mounting plate 3. The output shaft of the second motor 313 is fixedly connected with a bidirectional threaded rod 312. Both of the clamping plates 311 are threadedly connected with the bidirectional threaded rod 312.

[0034] When the present invention is in use, in order to prevent the steel coil from skewing during transportation, the output shaft of the second motor 313 drives the bidirectional threaded rod 312 to rotate. Under the limitation of the fourth groove 31, the bidirectional threaded rod 312 can drive the two clamping plates 311 to slide towards each other, so that the steel coil is located between the two clamping plates 311, realizing the limitation of the steel coil.

[0035] Furthermore, as Figure 4 and Figure 5 shown, two sixth grooves 322 are formed in the inner surface of the fifth groove 32. Third sliders 323 are slidably installed on the inner surface of the sixth grooves 322. The bottom of the third sliders 323 is fixedly connected with electric telescopic rods 324. A matching roller 321 is rotatably connected to the opposite surfaces of the two third sliders 323.

[0036] When the present invention is in use, the extension and retraction of the output end of the electric telescopic rod 324 can drive the third slider 323 to slide on the inner surface of the sixth groove 322, and the sixth groove 322 further drives the matching roller 321 to slide on the inner surface of the fifth groove 32, thereby achieving the purpose of changing the distance between the matching roller 321 and the feeding roller 331. This action enables the steel coil to be located between the feeding roller 331 and the matching roller 321 and can be driven by the feeding roller 331.

[0037] Working principle: When the present invention is in use, first place the steel coil between the inner wall of the bracket 1 and the first mounting plate 21. Then, rotate the threaded rod 241 by the output shaft of the first motor 242. Under the limitation of the two sliding rods 24, the first mounting plate 21 drives the loading roller 222 to slide at the bottom of the top plate 2 until the loading roller 222 is inserted into the inner cavity of the second groove 1②. Then, support the steel coil with the two loading rollers 222. Pulling the first mounting plate 21 by the first slider 202 can reduce the pressure on the sliding rod 24 and the threaded rod 241, avoiding the steel coil from bending the sliding rod 24 and the threaded rod 241. Next, pass one end of the steel coil through the bottom of the limiting roller 43. The limiting roller 43 presses the steel coil to prevent the steel coil from tilting too high during rotation. Rotate the bidirectional threaded rod 312 by the output shaft of the second motor 313. Under the limitation of the fourth groove 31, the two clamping plates 311 approach each other to limit the steel coil, preventing the steel coil from skewing during transportation.

[0038] When the output end of the electric telescopic rod 324 drives the third slider 323 to extend, the height of the matching roller 321 can be adjusted, thereby achieving the purpose of adjusting the distance between the matching roller 321 and the feeding roller 331. This action enables the matching roller 321 and the feeding roller 331 to clamp the steel coil, avoiding slippage between the feeding roller 331 and the steel coil when the feeding roller 331 rotates. During use, rotate the feeding roller 331 by the output shaft of the third motor 332 to convey the steel coil. When the feeding roller 331 rotates, the feeding roller 331 drives the third pulley 336 to rotate through the connecting shaft 333. After being transmitted by the second belt 335, the second pulley 334 also starts to rotate. The second pulley 334 drives the transmission rod 23 to rotate, and the transmission rod 23 drives the first pulley 22 to rotate. The first pulley 22 further drives the steel coil to rotate, making it easier to pull the steel coil. Rotate the fourth pulley 362 by the output shaft of the fourth motor 37. After being transmitted by the third belt 363, the fourth pulley 362 drives the incomplete gear 36 to rotate. The incomplete gear 36 can drive the rack 343 to move downward, and the rack 343 drives the cutting knife 342 to move downward to cut the steel coil. After the cutting is completed, the incomplete gear 36 is briefly disengaged from the rack 343. At this time, the second spring rod 35 extends to move the cutting knife 342 away from the steel coil. After the steel coil is cut, the discharging roller 364 rotates to move the cut steel coil away from the second mounting plate 3.
