Description

Technical Field

[0001] The invention relates to the technical field of medium and thick plate cutting, in particular to a roller cutting device for medium and thick plate production. Background Art

[0002] Medium and thick plates are a type of plate commonly used in engineering, whose thickness is much smaller than the plane size. Compared with thinner plates and thicker extra-thick plates, medium and thick plates have unique advantages in mechanical strength and processing performance. Medium and thick plates are widely used, including steel structures in construction projects, high-strength components in machinery manufacturing, container manufacturing such as furnace shells and boilers, shipbuilding steel plates, and bridge structures.

[0003] In the manufacturing process of medium and thick plates, the steel billets will be straightened after high-temperature rolling in a hot furnace. After straightening, they will be naturally cooled. However, after high-temperature rolling, defects such as cracking and "opening" often occur at both ends of the medium and thick plates. These parts are often called "heads and tails". In order to ensure the quality of the finished product, these unqualified parts usually need to be cut and sheared into the required length. During the high-temperature rolling process of the medium and thick plates, the surface of the steel plates reacts with the oxygen in the air to form oxides, and the existing cutting and shearing devices usually do not have a cleaning mechanism. If the oxide scale is not cleaned, the presence of the oxide scale will cause the shear blade to be subjected to uneven resistance during the cutting process, thereby affecting the flatness and accuracy of the shear section. At the same time, after the existing cutting and shearing devices have cut the medium and thick plates, there will usually be some burrs remaining on the cut surface, but the existing cutting and shearing devices usually do not have a grinding and deburring mechanism. However, if the burrs are not processed, the burrs may cause the actual size of the steel plate to deviate from the expected value, thereby affecting its accuracy in subsequent processing.

[0036] The storage box 13 is provided with an inner groove 32, and a slide box 33 is slidably connected to the inner side wall of the inner groove 32, and a plurality of hard bristles 40 are fixedly connected to the bottom of the slide box 33, and a plurality of pressing air bags 35 are arranged inside the slide box 33, and the interior of the pressing air bags 35 are respectively connected with an air suction port 36 and an air jet plate 41, and a pressure plate 37 is slidably connected to the interior of the inner groove 32, and outer slide bars 38 are fixedly connected to both sides of the pressure plate 37, and the outer slide bars 38 slide through the outside of the slide box 33, and a return spring 39 is sleeved on the outer side wall of the outer slide bar 38, and side plates 34 are fixedly connected to both sides of the slide box 33, and one end of the driving rod 14 away from the roller 9 is fixedly connected to the driving wheel 18, and a swing arm 31 is rotatably connected to the outer side wall of the driving wheel 18, and the other end of the swing arm 31 is rotatably connected On the outer wall of the side plate 34, a belt 42 is sleeved on one of the outer walls of the driving rods 14 on both sides, and the cleaning box 12 is rotatably connected to a rotating wheel 44.

[0037] In this embodiment, when in use, the rolled medium and thick steel plate can be inserted between the two conveying rollers 5, and the conveying rollers 5 are rotated to convey the medium and thick steel plate to be sheared to the cutting table 65. When the medium and thick steel plate reaches the cutting position, before cutting, the operator can turn on the starting motor 10 to drive the threaded rod 6 to rotate. When the threaded rod 6 rotates, the entire cleaning box 12 is driven to move to the right side of the chute 7 through the protrusion 11 (refer to Figure 1), when the cleaning box 12 moves to the right side of the slide groove 7, the roller 9 in contact with the slide groove 7 will rotate during the movement of the cleaning box 12. When the roller 9 rotates, it will drive the driving rod 14 to rotate synchronously. When the driving rod 14 rotates, it will drive the driving wheel 18 at its end to rotate. At this time, the driving wheel 18 will allow the slide box 33 to reciprocate in the inner groove 32 through the swing arm 31. The hard brush bristles 40 at the bottom will reciprocate and scrape the area to be cut of the medium and thick plate during the movement of the cleaning box 12, so as to remove the oxide scale on the surface of the medium and thick plate. When the slide box 33 moves back and forth, the outer slide bar 38 will first contact the side wall of the inner groove 32, and during the continuous reciprocating movement of the slide box 33, the pressing airbag 35 will be squeezed intermittently. When the pressing airbag 35 is intermittently squeezed, the external air will be sucked in through the air intake port 36, and then sprayed onto the surface of the medium and thick plate through the jet plate 41, so as to blow away the oxide scale and impurities cleaned by the hard bristles 40, thereby further improving the cleaning effect (it should be noted that both the air intake port 36 and the jet plate 41 are provided with a one-way valve).

[0038] Example 2: Please refer to Figure 1 - Fig.16 The grinding mechanism includes an outer box 52 fixedly connected to the outer wall of the driving member 57, an electromagnet 63 is provided at the end of the outer box 52, a grinding plate 53 is slidably connected to the inner wall of the outer box 52, an adsorption magnet 62 is provided on the grinding plate 53, a drip plate 54 is fixedly connected to the outer wall of the outer box 52, a through hole 55 is opened on the drip plate 54, a side box 51 is fixedly connected to the side wall of the cross plate 50, a pressing tube 59 is slidably connected to the inside of the side box 51, and a limiting collar 58 is fixedly connected to the outer wall of the pressing tube 59. An external spring 60 is fixedly connected to the positioning ring 58, a through hole 61 is opened inside the pressing tube 59, the inside of the side box 51 is connected to the water pipe 49, and the end of the water pipe 49 away from the side box 51 is connected to the inside of the water tank 29, and the side of the driving member 57 away from the outer box 52 is connected to the gear box 64, and the gear box 64 is provided with teeth 67 inside. The gear box 64 is rotatably connected inside, and the half gear 66 is meshed with the teeth 67. The outside of the half gear 66 is fixedly connected to the transmission rod 43.

[0039] In this embodiment, during the movement of the cleaning box 12 to the right side of the slide slot 7, the cleaning box 12 will not only clean the surface of the medium and thick plate, but the cleaning sponge 16 on the surface of the storage box 13 will also perfectly fit the outside of the cutting knife 3, and during the rightward movement of the cleaning box 12, the scraper 15 will scrape the surface of the cutting knife 3 to clean the iron filings attached to the surface of the cutting knife 3 due to cutting, thereby ensuring the cutting accuracy of the cutting knife 3. While the driving rod 14 drives the driving wheel 18 to rotate, it will also drive the knocking block 19 to intermittently knock the moving plate 25. When the moving plate 25 is intermittently knocked, it will cooperate with the tension of the tension spring 28 to make the moving plate 25 drive multiple trigger magnets 26 to reciprocate. When multiple trigger magnets 26 intermittently move to the positive side of the driving magnet 24 with the moving plate 25, under the action of the repelling magnetic force, the push rod 22 will be pushed into the spray barrel 20. On the contrary, when the trigger magnet 26 moves with the moving When the plate 25 moves to the side away from the driving magnet 24, the driving magnet 24 is far away from the trigger magnet 26 and the magnetic force is weak. Therefore, the push rod 22 will return to its original position under the elastic force of the driving magnet 24. Therefore, when the moving plate 25 is intermittently knocked by the knocking block 19, the push rod 22 will perform reciprocating suction motion in the spray barrel 20. When the push rod 22 performs reciprocating suction motion in the spray barrel 20, the water in the water tank 29 will be sucked into the inside of the spray barrel 20 through the water suction pipe 30, and then sprayed to the side of the cleaning sponge 16 through the infusion pipe 21. When the cleaning sponge 16 contacts the surface of the cutting scissors 3, a small amount of water is sprayed on the surface of the cutting scissors 3, so that the cutting temperature of the cutting scissors 3 can be reduced, and the friction and adhesion between the tool and the steel plate material can be reduced (it should be noted that both the infusion pipe 21 and the water suction pipe 30 are provided with a one-way valve to ensure that the infusion pipe 21 only sprays water and the water suction pipe 30 only absorbs water).

[0040] When the rotating threaded rod 6 drives the cleaning box 12 to move to the rightmost side of the slide slot 7 and does not block the cutting knife 3 from cutting, the operator can control the hydraulic rod 1 to extend, and then use the cutting knife 3 to cut the medium and thick plate. After the medium and thick plate is cut, the operator can continue to shorten the hydraulic rod 1 to drive the cutting knife 3 back to the original position. At this time, the operator can start the motor 10 to drive the threaded rod 6 to reverse. When the threaded rod 6 reverses, the cleaning box 12 will move from right to left (refer to Figure 1), at this time, the driving rod 14 will be reversed under the drive of the roller 9. When the driving rod 14 near the side of the cross plate 50 is reversed, the driving wheel 45 will be reversed through the drive of the belt 42. When the driving wheel 45 is reversed counterclockwise, the one-way plate 47 will abut the right angle edge of the one-way toothed disc 46, and drive the one-way toothed disc 46 and the transmission rod 43 to rotate synchronously. At this time, the half gear 66 at the end of the transmission rod 43 will rotate synchronously. Since the half gear 66 and the tooth 67 are meshing, when the half gear 66 rotates, it will cause The gear box 64 reciprocates left and right in the track 56. Since the outer box 52 on the back of the horizontal plate 50 is connected to the gear box 64 through the driving member 57, when the gear box 64 reciprocates, it will drive the outer box 52 to reciprocate. When the cleaning box 12 moves to the right, the electromagnet 63 will be powered off, so that the magnetic force between the electromagnet 63 and the adsorption magnet 62 disappears. At this time, the grinding plate 53 will slide down by its own weight, exposed outside the cleaning box 12, and just located at the side of the cutting edge of the cutting scissors 3 and contacting the cut of the medium and thick plate (refer to Fig.16 ), under the above principle, when the outer box 52 reciprocates, the grinding plate 53 exposed outside the cleaning box 12 will also reciprocate. When the cleaning box 12 moves from right to left, the cutout of the medium and thick plate is reciprocated and polished. When the outer box 52 reciprocates, the through hole 55 will intermittently contact the end of the pressing tube 59 and push the pressing tube 59 into the side box 51. When the pressing tube 59 is pushed into the side box 51 by the through hole 55, the through hole 61 enters the side box 51. At this time, the water in the side box 51 will flow into the pressing tube 59 through the through hole 61 in the side box 51, and drip onto the grinding plate 53 through the open end of the pressing tube 59 to moisten the grinding plate 53. Since the through hole 55 is in intermittent contact with the pressing tube 59, the pressing tube 59 will intermittently drip water to moisten the grinding plate 53 during the reciprocating movement of the outer box 52, taking away the heat and metal dust generated during the grinding process, thereby ensuring the removal effect of the cut burrs.

[0041] It should be noted that when the entire cleaning box 12 moves from left to right, the belt 42 will also drive the rotating wheel 44 to rotate forward. When the forward rotating wheel 44 causes the driving wheel 45 to rotate forward synchronously, the one-way plate 47 on the driving wheel 45 will continuously contact the beveled edge of the one-way toothed disc 46 and will not drive the one-way toothed disc 46 to rotate. Correspondingly, the transmission rod 43 will not drive the half gear 66 to rotate. At this time, the outer box 52 will not shake, and when the entire cleaning box 12 moves from left to right to clean the surface of the medium and thick plate, the electromagnet 63 is energized at this time, and the grinding plate 53 will be adsorbed into the inside of the outer box 52 and will not block the movement of the cleaning box 12, thereby achieving the technical effect of cleaning the surface of the medium and thick plate when the entire cleaning box 12 moves from left to right.

[0042] It should be noted that the water inside the infusion tube 21 will be transported to the inside of the side box 51 by the inclined water pipe 49 to ensure the water supply inside the side box 51, and the water inside the water tank 29 can be connected externally through an external water hose to ensure the water volume inside the water tank 29.

[0043] It should be noted that the side of the shearing table 65 is located directly below the cutting edge of the shearing blade 3, and when the grinding plate 53 is extended, it contacts the side of the shearing table 65. Therefore, when the shearing blade 3 cuts the medium and thick plate along the side of the shearing blade 65, the extended grinding plate 53 will just contact the cut of the medium and thick plate and perform grinding during the movement (refer to Fig.16 ).

[0044] It should be noted that a sewage outlet is provided inside the sewage storage box 17, and a micro suction pump is provided inside the sewage outlet. When the sewage storage box 17 is full, the sewage can be automatically sucked out through the sewage outlet.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
