Description

Technical Field

[0001] The invention relates to the technical field of hydraulic shearing, and in particular to a hydraulic shearing device and a production method. Background Art

[0002] Steel billet is a semi-finished product obtained by initial rolling or blooming of steel ingots, and is the raw material for various steel rolling mills. The cross-sections of steel billets include square, round, flat, rectangular and special-shaped ones, which are mainly related to the shape of the rolled product. When rolling simple cross-section steel, square billets or rectangular billets with cross-sections similar to those of the finished product are selected. When rolling flat products such as flat steel and angle steel, rectangular billets or flat billets are selected. It is best to use special-shaped billets when producing I-beams and channel steels to facilitate the rolling process and improve the yield rate. Round billets are the raw materials for the production of seamless pipes. After the billets are produced, they need to be rolled for further processing. Before rolling, the hot billets need to be sheared to ensure the quality of subsequent products.

[0003] A Chinese patent document with authorization announcement number CN109940212B discloses a gantry shearing machine, which can shear sheet materials into small pieces, has high production efficiency, and does not require direct human involvement in the entire intermediate process, thus ensuring safety.

[0004] However, the structural design of the above-mentioned related technology is as follows: during the shearing process of the steel billet, since there are more oxide scales on the surface of the hot steel billet, these oxide scales will fall onto the receiving platform when the steel billet is sheared or vibrated. However, during the production process, it is inconvenient for the staff to approach the receiving platform. If it is not cleaned in time, the oxide scales will easily solidify on the receiving platform after cooling, which will not only make subsequent cleaning inconvenient, but also when there are more oxide scales, the hot steel billet that subsequently enters the receiving platform will be affected by the oxide scales, causing the position to shift or the end to warp, thereby affecting the shearing quality of the hot steel billet.

[0005] Therefore, a hydraulic shearing device and a production method are proposed to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides a hydraulic shearing device and a production method, aiming to solve the problem in the related art that oxide scale remains on a material receiving platform and easily affects the shearing quality of hot steel billets.

[0007] The hydraulic shearing device of the present invention comprises a supporting mechanism, a shearing mechanism and a pressing mechanism, a receiving mechanism for supporting the steel billet is provided below the pressing mechanism, and a cleaning mechanism for cleaning oxide scale is provided inside the receiving mechanism; The pressing mechanism comprises a pressing block slidably connected to the supporting mechanism, and two pressing rods are arranged on both sides of the pressing block; The material receiving mechanism comprises a material receiving assembly and a flip assembly rotatably connected to the material receiving assembly. When the flip assembly rotates, the side with the oxide skin faces the inside of the material receiving assembly. Both sides of the material receiving assembly are rotatably connected with the extrusion assembly. The cleaning mechanism includes two scraping assemblies and two groups of adjusting assemblies slidably connected inside the material receiving assembly. The two scraping assemblies are respectively installed on the two groups of adjusting assemblies to drive the scraping assemblies to scrape the oxide scale on the flip assembly. The scraping assemblies are located below the flip assembly. The adjustment component includes a movable seat, a slide plate elastically slidably connected to the movable seat in a vertical direction, and a support rod installed on the slide plate. The scraping component is arranged on the support rod. An adjustment plate capable of contacting the extrusion component is provided on one side of the slide plate. Two locking components are installed on the slide plate. A limit component for locking the locking component is installed in the movable seat to limit the upward movement of the slide plate.

[0008] After the billet is sheared, the flip assembly rotates and faces the side with the oxide scale toward the inside of the receiving assembly. Then the two sets of movable seats drive the two scraping assemblies to move at the bottom of the flip assembly respectively to scrape off part of the oxide scale on the flip assembly. When the movable seat moves to the extreme position, the flip assembly rotates, and at the same time the extrusion assembly squeezes the adjustment plate downward to move the slide plate downward, thereby driving the scraping assembly to gradually move downward to scrape off another part of the oxide scale on the flip assembly. When the flip assembly is flipped to a vertical state, the scraping assembly is separated from the flip assembly, and all the oxide scale on the flip assembly is scraped off.

[0009] Preferably, the pressing mechanism includes a telescopic part 2 installed on the supporting mechanism, a buffer cylinder installed on the telescopic part 2 and a pressing block installed on the buffer cylinder, and sliding blocks are installed on both sides of the pressing block, and two pressing rods for squeezing the adjusting plate are installed on both sides of the sliding block to release the restriction of the limiting assembly on the sliding plate.

[0010] The pressing block can be driven downward by the telescopic member 2. When the pressing block moves downward, the adjusting plate can be driven downward by the pressure rod. The adjusting plate drives the locking assembly downward through the slide plate, so that the limiting assembly releases the limit on the locking assembly, thereby releasing the limit on the scraping assembly.

[0011] Preferably, the material receiving assembly comprises a material receiving platform located below the material pressing block, the top of the material receiving platform has an upward opening, and the flip assembly is located in the opening of the material receiving platform.

[0012] Preferably, the turnover assembly comprises two material receiving plates rotatably connected in the opening of the material receiving platform, and the top of the material receiving plates and the top of the material receiving platform are located in the same horizontal plane.

[0013] Preferably, the extrusion assembly includes two rotating plates, both of which are equipped with fixed columns, and the fixed columns are rotatably connected to one side of the material receiving assembly. The rotating plates can squeeze the adjustment plates to drive the scraping assembly to move downward.

[0014] When the scraping assembly contacts the receiving plate, the adjusting plate contacts the rotating plate. When the rotating plate rotates, the adjusting plate can be pressed down. At this time, the adjusting plate can drive the scraping assembly to move downward through the sliding plate.

[0015] Preferably, the scraping assembly comprises a fixed plate and a scraper, the fixed plate is mounted on a support rod, two movable rods elastically slidably connected in a lateral direction are provided on the fixed plate, and the scraper is mounted on the movable rod.

[0016] By elastically arranging the scraper on the fixed plate, the scraper can always be in contact with the side of the receiving plate with the oxide scale.

[0017] Preferably, the locking assembly comprises a connecting plate and a locking block, the connecting plate is mounted on the bottom of the skateboard, the locking block is connected to the connecting plate by a transverse sliding connection via an elastic component, and the bottom of the locking block has an inclined surface.

[0018] Preferably, the limit assembly includes a fixed rod, a vertical rod, a limit block and a movable block, the fixed rod is installed on the movable seat, the vertical rod is installed on the fixed rod, the limit block is installed on the top end of the vertical rod, and the movable block is slidably connected to the outside of the vertical rod. The limit block and the movable block are both truncated cone-shaped, and a boss is provided at one end of the movable block facing the limit block, and a groove for accommodating the boss is provided at the bottom end of the limit block.

[0019] The effect is that when the rotating plate drives the adjusting plate to move down to the extreme position, the locking block moves to the bottom of the limit block. At this time, the limit block can prevent the sliding plate from moving up, thereby preventing the scraper from moving up and affecting the rotation of the docking plate.

[0020] A hydraulic shearing production method, using the above hydraulic shearing device, comprises the following steps: S1: The billet is conveyed to the receiving table and placed above the receiving plate, and then the pressing block is pressed on the top of the billet, and at the same time, the pressing rod moves down and squeezes the adjusting plate, so that the two locking blocks are clamped on the movable block; S2: After the billet is cut, the pressing block moves upward, so that the two locking blocks pass over the limit blocks to unlock the scraper, so that the scraper contacts the bottom of the receiving plate; S3: The movable seat moves in the receiving table, so that the two scrapers move at the bottom of the receiving plate to scrape off the oxide scale at the bottom of the receiving plate; S4: When the scraper passes over the middle of the lower surface of the receiving plate, the two receiving plates rotate, and the rotating plate squeezes the adjusting plate, so that the scraper gradually moves downward. During the downward movement of the scraper, the remaining oxide scale at the bottom of the receiving plate is scraped off; S5: When the slide plate moves down to the initial position, the locking block is limited by the limit block to lock the scraper.

[0021] After the steel billet is sheared, the receiving plate rotates and faces the side with oxide scale to the inside of the receiving table. Then the two sets of movable seats drive the two scrapers to move at the bottom of the receiving plate to scrape off part of the oxide scale on the receiving plate. When the movable seat moves to the extreme position, the two receiving plates rotate, and at the same time the rotating plate presses the adjusting plate downward to move the slide plate downward, thereby driving the scraper to gradually move downward to scrape off another part of the oxide scale on the receiving plate.

[0022] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: after the steel billet is sheared, the flipping assembly rotates and faces the side with the oxide scale toward the inside of the material receiving assembly, and then the two groups of movable seats respectively drive the two scraping assemblies to move at the bottom of the flipping assembly to scrape off part of the oxide scale on the flipping assembly. When the movable seat moves to the extreme position, the flipping assembly rotates, and at the same time the extrusion assembly squeezes the adjustment plate downward to move the slide plate downward, thereby driving the scraping assembly to gradually move downward to scrape off another part of the oxide scale of the flipping assembly. When the flipping assembly rotates to a vertical state, the scraping assembly is separated from the flipping assembly. At this time, all the oxide scale on the flipping assembly is scraped off to prevent the upward side of the flipping assembly from having oxide scale, thereby preventing the oxide scale from solidifying on the flipping assembly, and avoiding the solidified oxide scale from affecting the cutting quality of the steel billet.

[0042] Continue to refer Figures 2 to 4 As shown, the flip assembly 42 includes two receiving plates 421 disposed opposite to each other, and a heat conducting plate is disposed inside the receiving plate 421, through which the heat at the top of the receiving plate 421 can be quickly transferred to the bottom of the receiving plate 421, so as to heat the oxide scale bonded to the bottom of the receiving plate 421, which is convenient for subsequent cleaning. The top of the receiving plate 421 is located at the same level as the top of the receiving platform 411. A rotating rod 422 is installed in the middle of the two material receiving plates 421, and the rotating rod 422 is rotatably connected to the inner wall of the material receiving platform 411. Both ends of the rotating rod 422 pass through the material receiving platform 411 and extend to the outside of the material receiving platform 411. Both ends of the rotating rod 422 are installed with a transmission wheel 423 that is transmission-connected to the extrusion assembly 48. A transmission wheel 2 424 is installed on the outer side of one end of the rotating rod 422 close to the trapezoidal step of the material receiving platform 411, and a gear 44 is installed at one end of the other rotating rod 422. A motor 43 is installed at one end of the gear 44, and one end of the motor 43 is installed on the inner side of the side frame 12.

The gear 2 45 can drive the rotating rod 422 close to the trapezoidal steps of the receiving platform 411 to rotate through the transmission wheel 3 47 on the rotating shaft 46, so that the two receiving plates 421 rotate relative to each other to change the orientation of the receiving plates 421 so that the side without oxide scale faces upward, and the side with oxide scale faces the inside of the receiving platform 411 to collect the oxide scale.

[0045] Continue to refer Figure 3 to Figure 4 As shown, the extrusion assembly 48 includes two rotating plates 483, and a fixed column 481 is installed in the middle of the two rotating plates 483.

When moving, the adjustment assembly 52 can drive the scraping assembly 51 to move at the bottom of the receiving plate 421 to scrape off part of the oxide scale adhering to the receiving plate 421. When the receiving plate 421 rotates, the scraping assembly 51 can be driven downward by the adjustment assembly 52 to scrape off another part of the oxide scale on the receiving plate 421 to prevent the upward side of the receiving plate 421 from having solidified oxide scale.

[0049] like Figure 5 As shown, the scraping assembly 51 includes a fixed plate 511 and a scraper 514. The fixed plate 511 is mounted on the adjustment assembly 52. ​​Two movable rods 512 are slidably connected to the fixed plate 511.

Locking assemblies 57 are installed on both sides of the bottom of the slide plate 522. A limiting assembly 58 is installed in the middle of the inner bottom wall of the movable seat 521. When the slide plate 522 is reset, the locking assembly 57 can be limited by the limiting assembly 58 to prevent the scraper 514 from moving up again.

[0051] like Figure 5 to Figure 6 As shown, guide rods 524 are installed on both sides of the inner bottom wall of the movable seat 521, and the guide rods 524 are slidably connected to the slide plate 522. The top of the guide rods 524 passes through the slide plate 522 and is installed on the inner top wall of the movable seat 521. A spring 525 is installed between the inner bottom wall of the movable seat 521 and the slide plate 522 to drive the scraper 514 to reset.

An adjustment plate 527 is installed on one end of the extension rod 526. The bottom end of the pressure rod 35 is arranged on the upper side of the adjustment plate 527. When the pressure block 33 moves downward, the slider 34 drives the pressure rod 35 to move downward. During the downward movement, the pressure rod 35 can press down the adjustment plate 527, thereby driving the slide plate 522 to move downward. When the pressure rod 35 is separated from the adjustment plate 527, the locking assembly 57 is separated from the limiting assembly 58 to unlock the slide plate 522, so that the scraper 514 moves upward.

[0053] When the rotating plate 483 rotates, it can squeeze the adjusting plate 527 to move the adjusting plate 527 downward. When the adjusting plate 527 moves downward, it can drive the sliding plate 522 to move downward. At the same time, the sliding plate 522 can drive the scraper 514 to move downward through the supporting rod 523.

[0054] like Figures 4 to 6 As shown, a movable plate 528 is installed at the bottom of one side of each movable seat 521, and the movable plate 528 is slidably connected in the slide groove 412.

The connecting seat 541 is installed on one side of the receiving platform 411, one end of the bidirectional lead screw 542 is rotatably connected to one side of the inner wall of the connecting seat 541, and the other end of the bidirectional lead screw 542 is installed with a connecting shaft 543, one end of the connecting shaft 543 is installed with a motor 2 544, and the motor 2 544 is installed on the side frame 12. Two movable plates 528 close to the connecting seat 541 are respectively threadedly connected to the two ends of the bidirectional lead screw 542.

[0056] The second motor 544 drives the bidirectional lead screw 542 to rotate via the connecting shaft 543 , and the bidirectional lead screw 542 drives the two movable seats 521 to approach each other via the two movable plates 528 , thereby driving the two scrapers 514 to approach each other.

[0057] like Figures 6 to 8As shown, the locking assembly 57 includes a connecting plate 571 and a locking block 575. The connecting plate 571 is installed on one side of the bottom of the slide plate 522. A mounting groove 572 is provided at the bottom of one side of the connecting plate 571.

A connecting block 574 slidably connected to the mounting groove 572 is installed at one end of the spring three 573. The connecting block 574 is T-shaped. One side of the locking block 575 is installed on one side of the connecting block 574. The bottom of the locking block 575 has an inclined surface.

[0058] Continue to refer Figures 6 to 8 As shown, the limiting assembly 58 includes a fixed rod 581, a vertical rod 582, a limiting block 583 and a movable block 584. The fixed rod 581 is installed in the middle of the inner bottom wall of the movable seat 521, and the bottom end of the vertical rod 582 is installed on the top of the fixed rod 581. The limiting block 583 is installed on the outer side of the top end of the vertical rod 582, and the movable block 584 is slidably connected to the outer side of the bottom end of the vertical rod 582. The diameter of the fixed rod 581 is larger than the diameter of the vertical rod 582 to prevent the movable block 584 from sliding onto the fixed rod 581. The limiting block 583 and the movable block 584 are both truncated cone-shaped. In the initial position, the top of the locking block 575 contacts the bottom end of the limiting block 583. The limiting block 583 and the movable block 584 are arranged relative to each other, and a boss is arranged on one end of the movable block 584 facing the limiting block 583, and a groove for accommodating the boss is opened at the bottom end of the limiting block 583. When the locking block 575 moves downward, the locking block 575 can move toward the inside of the installation groove 572 under the limit of the boss on the movable block 584.

[0059] When the adjusting plate 527 is squeezed and drives the sliding plate 522 to move downward, the sliding plate 522 drives the locking block 575 to move downward through the connecting plate 571. When one side of the locking block 575 contacts the outer side of the movable block 584, under the action of the spring three 573, the two locking blocks 575 can be clamped on the movable block 584. When the adjusting plate 527 loses the squeezing force, under the action of the spring two 525, the sliding plate 522 can be pushed upward. At the same time, the two locking blocks 575 drive the movable block 584 to move upward and make the boss on the movable block 584 enter the limit block 583, so that the two locking blocks 575 can pass the limit block 583 to unlock the scraper 514.

[0060] Working principle: When shearing the steel billet, the steel billet is first transported to the receiving platform 411 and placed above the receiving plate 421, and then the pressure block 33 is pressed on the top of the steel billet. When the pressure block 33 moves downward, the slider 34 drives the pressure rod 35 to move downward and squeeze the adjustment plate 527, thereby driving the slide plate 522 to move downward. At this time, the two locking blocks 575 are clamped on the movable block 584. After the steel billet is cut, the pressure block 33 moves upward. At this time, the two locking blocks 575 pass over the limit block 583 to unlock the scraper 514, so that the scraper 514 contacts the bottom of the receiving plate 421, and the adjustment plate 527 contacts the bottom of the rotating plate 483.

[0061] When the scraper 514 contacts the material receiving plate 421, the motor 2 544 drives the bidirectional lead screw 542 to rotate through the connecting shaft 543, and the bidirectional lead screw 542 drives the two movable seats 521 to approach each other through the two movable plates 528, thereby driving the two scrapers 514 to move at the bottom of the material receiving plate 421 to scrape off the oxide scale at the bottom of the material receiving plate 421. When the scraper 514 passes over the middle of the lower surface of the material receiving plate 421, the movable seat 521 moves to the limit position, and then drives the two material receiving plates 421 to rotate through the motor 1 43. At the same time, the rotating plate 483 rotates synchronously with the receiving plate 421. When the rotating plate 483 rotates, it squeezes the adjusting plate 527, so that the scraper 514 gradually moves downward. At the same time, the receiving plate 421 squeezes the scraper 514, so that the scraper 514 approaches the fixed plate 511. During the downward movement of the scraper 514, the remaining oxide scale on the bottom of the receiving plate 421 can be scraped off, so that the bottom of the receiving plate 421 does not have oxide scale when facing upward, thereby preventing the oxide scale from solidifying on the receiving plate 421, and avoiding the solidified oxide scale from affecting the cutting quality of the steel billet.

[0062] When the scraper 514 moves downward, the slide plate 522 moves downward synchronously with the scraper 514. When the receiving plate 421 rotates to a vertical state, the slide plate 522 moves downward to the initial position. At this time, the locking block 575 is limited by the limit block 583 to lock the scraper 514 to prevent the scraper 514 from moving up again and affecting the rotation of the receiving plate 421. When the oxide scale is cleaned, the movable seat 521 can be reset by the reverse rotation of the motor 2 544, thereby driving the scraper 514 to reset.

[0063] The hydraulic shearing production method of the present invention is carried out using the above-mentioned hydraulic shearing device, and comprises the following steps: S1: The steel billet is conveyed to the receiving platform 411 and placed above the receiving plate 421, and then the pressing block 33 is pressed on the top of the steel billet, and at the same time, the pressing rod 35 moves downward and presses the adjusting plate 527, so that the two locking blocks 575 are clamped on the movable block 584; S2: After the steel billet is cut, the pressing block 33 moves upward, so that the two locking blocks 575 pass over the limit blocks 583 to unlock the scraper 514, so that the scraper 514 contacts the bottom of the receiving plate 421; S3: The second motor 544 drives the movable seats 521 on the two movable plates 528 to move closer to each other through the bidirectional lead screw 542, thereby driving the two scrapers 514 to move at the bottom of the receiving plate 421 to scrape off the oxide scale at the bottom of the receiving plate 421; S4: When the scraper 514 passes over the middle of the lower surface of the receiving plate 421, the motor 1 43 drives the two receiving plates 421 to rotate, and the rotating plate 483 rotates synchronously with the receiving plate 421. When the rotating plate 483 rotates, it squeezes the adjusting plate 527, so that the scraper 514 gradually moves downward. During the downward movement of the scraper 514, the remaining oxide scale on the bottom of the receiving plate 421 is scraped off; S5: When the slide plate 522 moves down to the initial position, the locking block 575 is limited by the limiting block 583 to lock the scraper 514; S6: After the oxide skin is cleaned, the motor 2 544 rotates in the reverse direction to drive the movable seat 521 to reset, thereby driving the scraper 514 to reset.
