Description

Technical Field

[0001] This invention belongs to the field of cutting equipment technology, and specifically relates to a strip steel cutting device. Background Technology

[0002] Steel strip, also known as steel strip, is a narrow and long flat steel product, usually supplied in coil form. Due to its high dimensional accuracy, good surface quality, and ease of processing, it has become an important raw material in industrial production. Steel strip cutting equipment is a core component of steel strip processing production lines. Based on the cutting direction and function, it can be mainly divided into two categories: longitudinal shearing and transverse shearing. Among transverse shearing equipment, the flying shear is a common type. It can complete the shearing without stopping the production line, making it a key piece of equipment for achieving high-speed, continuous production in industries such as steel rolling and papermaking. However, flying shears present the following problems during use: 1. In the current flying shear machine, steel coils are usually cut into uniformly sized plates. During the flying shearing process, dust, impurities and oil stains easily adhere to the steel coils. These impurities, dust and oil stains will affect the cutting accuracy. At the moment of cutting, they will be caught between the upper and lower cutting blades, like an abrasive, which may cause uneven cut edges, burrs, or even chipping of the cutting blades, seriously affecting product quality.

[0003] 2. During long-term use, metal scraps and impurities from existing flying shears will adhere to the shearing blade. If these impurities are not cleaned in time, they will sinter onto the blade under high temperature and pressure, forming "nodules". Nodules will change the geometric angle of the blade, causing changes in the shearing gap, directly resulting in burrs, unevenness, or even scratches on the surface of the strip steel. At the same time, nodules will cause local overheating of the shearing blade, causing the blade to anneal, resulting in a decrease in hardness, rapid dulling of the blade, and even plastic deformation. Summary of the Invention

[0015] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, this invention achieves simultaneous leveling of the upper and lower surfaces of the strip steel by using the first and second leveling components in the leveling and cleaning mechanism, ensuring that the strip steel entering the shearing machine is in a flat state and guaranteeing the quality of shearing.

[0016] 2. Unlike existing technologies, this invention uses a cleaning component in a leveling and cleaning mechanism to perform axial rotation cleaning of the upper and lower surfaces of the conveyor belt, and uses a reciprocating cleaning component to perform radial reciprocating brushing cleaning, achieving synchronous radial and axial cleaning. This avoids the problem of incomplete cleaning caused by unidirectional brushing cleaning, effectively removing residual dust and impurities on the conveyor belt, and in conjunction with a suction component, it absorbs and collects the cleaned impurities and dust.

[0017] 3. Unlike existing technologies, this invention utilizes a combination of a chip-blowing cooling mechanism and a shearing mechanism. During each shearing process, the piston is simultaneously driven downward to blow air, thus cleaning up debris and impurities on the shearing blade during each shearing operation. This prevents debris and impurities from accumulating on the shearing blade. Furthermore, the air blowing process simultaneously cools the shearing blade, preventing overheating and the resulting "nodule" problem. This extends the service life of the shearing blade and ensures the quality of the shearing process.

[0018] 4. Unlike existing technologies, during the piston's downward press, the reciprocating assembly is driven to work simultaneously. The reciprocating assembly drives the diverter pipe and the jet nozzle to reciprocate, realizing the reciprocating swing of the shearing blade and blowing air, achieving dynamic dust blowing and good dust cleaning effect.

The base plate 37 is provided on the frame 1. A suction component 38 is provided on both the first leveling component 35 and the second leveling component 36.

[0025] Please see Figure 4 , Figure 5 and Figure 6 A guide rod 33 is movably passed through the top of the U-shaped steel beam 31. The bottom of the guide rod 33 is fixedly connected to the top of the gantry frame 34. The second leveling component 36 includes a mounting plate 361 fixedly installed on the top of the base plate 37. The mounting plate 361 has a mounting groove in the center. Several leveling rollers 362 are rotatably installed on the rear side of the mounting groove. A cleaning component 363 is provided on the front side of the mounting groove. A collection box 365 is fixedly installed on the bottom of the mounting plate 361. A reciprocating cleaning component 39 is provided between the cleaning component 363 and the collection box 365. A top plate 366 is fixedly installed on the top of the mounting plate 361.

[0026] Please see Figure 4 , Figure 5 and Figure 6The cleaning component 363 includes two drive rollers 3638 rotatably mounted inside the mounting groove. A conveyor belt 3632 is fitted around the two drive rollers 3638. A cleaning cloth 3631 for cleaning the surface of the strip is detachably fitted around the conveyor belt 3632. A servo motor 3635 is fixedly mounted on the base plate 37 on the right side. The output end of the servo motor 3635 rotates through the base plate 37 and is fixedly mounted on a fixed shaft. A cleaning roller 3633 for cleaning the bottom of the cleaning cloth 3631 is fixedly mounted on the left end of the fixed shaft. A scraper 364 for scraping the front surface of the conveyor belt 3632 is installed inside the collection box 365. A side plate 3636 is rotatably fitted on the right side of the central shaft of the drive roller 3638 on the rear side. The side plate 3636 is fixedly mounted inside the mounting groove. A second gear 3637 is fixedly fitted on the right end of the central shaft of the drive roller 3638 on the rear side. A first gear 3634 that meshes with the second gear 3637 is fixedly fitted on the right side of the fixed shaft.

[0027] Please see Figure 5 , Figure 6 and Figure 7 The reciprocating cleaning assembly 39 includes a first synchronous pulley 391 fixedly sleeved on a fixed shaft, a mounting shaft 393 rotatably mounted on the front side of the base plate 37, a second synchronous pulley 398 fixedly sleeved on the right end of the mounting shaft 393, a synchronous belt 392 meshing between the second synchronous pulley 398 and the first synchronous pulley 391, an inclined pulley 397 fixedly sleeved on the left end of the mounting shaft 393, a movable rod 395 movably passing through the inside of the collection box 365, a flat cleaning brush 394 fixedly mounted on the top of the movable rod 395 and attached to the bottom of the conveyor belt 3632, two L-shaped arms 396 fixedly mounted on the right end of the movable rod 395, and ball bearings rotatably mounted on the top of the two L-shaped arms 396 and attached to the bottom side wall of the inclined pulley 397.

[0028] Please see Figure 3 and Figure 4 The suction assembly 38 includes a vacuum cleaner 382 fixedly installed on the top of the first leveling assembly 35. The vacuum cleaner 382 is prior art and will not be described in detail here. The suction end of the vacuum cleaner 382 is fixedly connected to a suction pipe 384. The end of the suction pipe 384 away from the vacuum cleaner 382 is fixedly connected to a corrugated connecting pipe 383. The two suction ends of the corrugated connecting pipe 383 are respectively fixedly connected to suction hoods 381. The suction hoods 381 are located inside the first leveling assembly 35 and the second leveling assembly 36, respectively.

[0029] In operation, the strip steel is first conveyed from back to front to the leveling and cleaning mechanism 3 using a traction mechanism (not shown in the figure) and a conveying mechanism (not shown in the figure). The leveling and cleaning mechanism 3 is then adjusted according to the thickness of the strip steel. At this point, the top plate 366 of the second leveling component 36 is horizontal, and the bottom of the strip steel is in contact with the top of the cleaning component 363. Then, the first hydraulic cylinder 32 is activated, extending its output end and driving the gantry 34 and the first leveling component 35 on it downwards until the bottom of the first leveling component 35 is in contact with the top of the strip steel. The leveling roller 362 has a built-in pressure sensor (not shown in the figure) to detect the pressure applied to the strip steel, ensuring the pressure is within an appropriate range. The adjustment is based on the thickness of the strip steel. After adjusting the spacing between the first leveling component 35 and the second leveling component 36 to a suitable thickness, the servo motor 3635 is started synchronously. The output of the servo motor 3635 drives the fixed shaft and the first gear 3634 on it to rotate synchronously, which in turn drives the second gear 3637 and the transmission roller 3638 on it to rotate synchronously. This, in turn, drives the conveyor belt 3632 and the cleaning cloth 3631 on it to rotate synchronously. The direction of movement of the cleaning cloth 3631 is opposite to the conveying direction of the strip steel, thereby using the cleaning cloth 3631 to clean the upper and lower surfaces of the strip steel synchronously, preventing strip steel with dust and impurities from entering the shearing mechanism 4. The transmission ratio between the first gear 3634 and the second gear 3637 is 1:4, that is, the rotational speed of the cleaning roller 3633 is 1:4 of the transmission roller 3637. At 8 times the speed of rotation, the cleaning roller 3633 rotates to clean the cleaning cloth 3631, effectively removing dust and impurities. During the rotation of the cleaning roller 3633, it simultaneously drives the first synchronous pulley 391 and its synchronous belt 392 to rotate. The synchronous belt 392 drives the second synchronous pulley 398 and its mounting shaft 393 to rotate, which in turn drives the inclined pulley 397 to rotate. Because the inclined pulley 397 is designed to be tilted, its rotation simultaneously drives the L-shaped arm 396 and its movable rod 395 to reciprocate linearly, which in turn drives the flat cleaning brush 394 to clean the bottom of the cleaning cloth 3631. The rotation of the cleaning roller 3633 effectively cleans the cleaning cloth 3631. Axial rotation cleaning and a flat cleaning brush 394 perform radial reciprocating linear cleaning on the bottom of the cleaning cloth 3631, achieving both radial and axial cleaning and self-cleaning of the cleaning cloth 3631, thus shortening the maintenance cycle. Meanwhile, the cleaning roller 3633 and flat cleaning brush 394 in the first leveling assembly 35 are located on top of the cleaning cloth 3631. Therefore, after brushing, dust and impurities still remain on the cleaning cloth 3631, and the scraper 364 scrapes and cleans the cleaning cloth 3631. At this time, the vacuum cleaner 382 is activated, sucking the dust and impurities through the suction hood 381 into the corrugated connecting pipe 383, and then through the suction pipe 384 into the collection box inside the vacuum cleaner 382 for collection. The corrugated connecting pipe 383 is a telescopic design.Therefore, it does not affect the lifting and lowering of the first leveling component 35. After cleaning, the strip steel is simultaneously squeezed and leveled using the leveling roller 362 and the first leveling component 35, thus achieving both leveling and cleaning of the strip steel.

[0030] Please see Figure 2 and Figure 8 The shearing mechanism 4 includes an upper shear arm 41 and a lower shear arm 42. The lower shear arm 42 is located below the upper shear arm 41. The upper shear arm 41 and the lower shear arm 42 work together to shear the strip steel. Under the drive of the synchronization mechanism 6, the upper shear arm 41 and the lower shear arm 42 swing back and forth synchronously to shear. During shearing, the horizontal component speed of the swing arm must be equal to the running speed of the strip steel to ensure that the steel does not pile up or pull during shearing. After shearing, the plate is transported to the next process by a conveyor belt.

[0031] Please see Figure 2 , Figure 8 and Figure 9 The chip blowing and cooling mechanism 5 includes a support frame 51 fixedly installed on the front sides of the upper shear arm 41 and the lower shear arm 42 respectively. A limit groove 54 is opened on the front side of the support frame 51. An air blowing assembly 53 is jointly provided on the support frame 51 and the lower shear arm 42. A reciprocating assembly 55 is provided on the air blowing assembly 53. The air blowing assembly 53 includes an upper hinge seat 531 fixedly installed on the upper shear arm 41. An upper telescopic rod 532 is rotatably installed at the bottom of the upper hinge seat 531. A fixed cylinder 534 is slidably sleeved at the bottom of the upper telescopic rod 532. The bottom of the fixed cylinder 534 is... A lower hinge seat 535 is hinged, and the bottom of the lower hinge seat 535 is fixedly installed on the lower scissor arm 42. A piston 533 is fixedly installed at the bottom of the upper telescopic rod 532. The piston 533 is slidably connected inside the fixed cylinder 534. A one-way air inlet valve is fixedly installed on one side of the bottom of the fixed cylinder 534. An air pipe 536 is fixedly connected to the other side of the bottom of the fixed cylinder 534. The end of the air pipe 536 away from the fixed cylinder 534 passes through the support frame 51 and is fixedly connected to the diverter pipe 537. Several air nozzles 52 are fixedly connected to the diverter pipe 537.

[0032] Please see Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11The reciprocating assembly 55 includes a fixed sleeve plate 552 fixedly mounted on the diverter pipe 537. A mounting square rod 553 is fixedly inserted through the fixed sleeve plate 552. An L-shaped plate 558 slides through the left end of the mounting square rod 553. The diverter pipe 537 also slides through the L-shaped plate 558. The L-shaped plate 558 is fixedly mounted on the inner wall of the support frame 51. A spring 551 is sleeved on the outside of the mounting square rod 553. The spring 551 is fixedly mounted between the inner wall of the support frame 51 and the L-shaped plate 558. A mounting base is fixedly installed on the right end of the mounting rod 553. A roller 555 is rotatably mounted on the mounting base. A fixing block 554 is fixedly installed on the rear side of the top of the upper telescopic rod 532. A connecting rod 556 is fixedly installed on the fixing block 554. A cam plate 557 that cooperates with the roller 555 is fixedly installed on the connecting rod 556. There are two cam plates 557. The two cam plates 557 are respectively set inside the two support brackets 51. The support brackets 51 have through holes for the connecting rod 556 to pass through.

[0033] During operation, when the upper shear arm 41 and lower shear arm 42 are cutting, the upper hinge seat 531 and its lower hinge seat 535 move synchronously, simultaneously driving the fixed cylinder 534 and the upper telescopic rod 532 to move synchronously. This, in turn, drives the piston 533 to compress the gas inside the fixed cylinder 534. The gas then enters the air pipe 536 and is then split by the diverter pipe 537 before being ejected from the nozzle 52. The gas then blows onto the shear blade, cleaning away debris and impurities. Simultaneously, the shear blade is cooled by the blowing air, effectively preventing overheating and the resulting "accumulation" problem, extending the blade's lifespan, and ensuring cutting quality. During the cutting process, the fixed block 554 and its connecting rod 556 move downwards, which in turn drives the cam plate 557 downwards. When the protruding part of the cam plate 557 contacts the roller 555, it... The compression drives the roller 555 and the mounting rod 553 to move to the left, simultaneously driving the fixed sleeve 552 and the diverter pipe 537 on it to move to the left, and at the same time driving the jet nozzle 52 to move to the left, thereby compressing the spring 551. When the concave position of the cam plate 557 contacts the roller 555, under the elastic force of the spring 551, the jet nozzle 52 is indirectly driven to move to the right, realizing the left and right reciprocating motion of the jet nozzle 52, realizing the left and right reciprocating jet blowing and cooling of the shearing blade. After the shearing is completed, the upper shear arm 41 and the lower shear arm 42 move in opposite directions, thereby driving the piston 533 to move away from the lower hinge seat 535, thereby drawing in air through the one-way valve on the fixed cylinder 534. The cold air from the outside enters the fixed cylinder 534, so that with the next shearing cut, the shearing blade is again cooled and dusted by blowing air. Then, with each shearing, the dust removal and cooling of the shearing blade are driven simultaneously.

[0034] It should be noted that, in use, this strip steel cutting device first uses a traction mechanism (not shown in the figure) and a conveying mechanism (not shown in the figure) to transport the strip steel from back to front into the leveling and cleaning mechanism 3. The leveling and cleaning mechanism 3 is adjusted, and then the first hydraulic cylinder 32 is activated. The output end of the first hydraulic cylinder 32 extends, synchronously driving the gantry frame 34 and the first leveling component 35 on it to move downwards until the bottom of the first leveling component 35 is in contact with the top of the strip steel. Thus, the leveling roller 362 and the first leveling component 35 simultaneously compress and level the strip steel. After leveling, the strip steel is cleaned by the cleaning component 36. 3. The upper and lower surfaces of the strip are simultaneously rotated and cleaned. The reciprocating cleaning component 39 performs simultaneous reciprocating linear cleaning on both surfaces, thus combining axial rotational cleaning and radial reciprocating linear cleaning for excellent cleaning results. At this point, the vacuum cleaner 382 is activated, drawing dust and impurities through the suction hood 381 into the corrugated connecting pipe 383, and then through the suction pipe 384 into the collection box within the vacuum cleaner 382 for collection. This simultaneously achieves strip leveling and cleaning. After leveling, the strip is subjected to reciprocating oscillating shearing by the shearing mechanism 4. The strip steel is sheared into uniformly sized plates. Simultaneously, during the shearing process, the fixed cylinder 534 and the upper telescopic rod 532 move synchronously to center, which in turn drives the piston 533 to compress the gas inside the fixed cylinder 534. The gas then enters the air pipe 536 synchronously, and is subsequently split by the diverter pipe 537 and ejected from the nozzle 52. During the shearing process, the fixed block 554 and its connecting rod 556 move downwards, which in turn drives the cam plate 557 downwards. When the protruding part of the cam plate 557 contacts the roller 555, it compresses and drives the roller... The wheel 555 and the mounting rod 553 move to the left, synchronously driving the fixed sleeve 552 and the diverter pipe 537 on it to move to the left, and at the same time driving the air nozzle 52 to move to the left, thereby compressing the spring 551. When the concave position of the cam plate 557 contacts the roller 555, under the elastic force of the spring 551, the air nozzle 52 is indirectly driven to move to the right, realizing the left and right reciprocating motion of the air nozzle 52. This realizes the left and right reciprocating air jet blowing and cooling of the shearing blade, effectively avoiding the problem of "accumulation" caused by overheating of the shearing blade, extending the service life of the shearing blade, and ensuring the quality of shearing.
