Description

Technical Field

[0001] This invention relates to the field of scrap steel cutting technology, and in particular to a processing and cutting device for scrap steel recycling. Background Technology

[0002] Steel smelting generates tens of millions of tons of scrap steel every year, which varies greatly in shape and size. At the same time, scrap steel of different shapes also exists in various industries, making scrap steel processing quite difficult.

[0003] Traditional clamps often struggle with workpieces of enormous size, resulting in sawing vibrations and rough cut surfaces due to insufficient clamping force. Furthermore, the random posture and center of gravity of scrap steel on the conveyor chain prevent continuous and uniform feeding, causing the saw blade to frequently spin idly or jam, wasting resources, accelerating wear, and affecting processing efficiency.

[0004] Therefore, we propose a processing and cutting device for scrap steel recycling. Summary of the Invention

Detailed Implementation

[0019] 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.

[0020] Example 1: Please refer to Figures 1-12A processing and cutting device for scrap steel recycling includes a base 1, a first mounting block 2 threadedly fixed to one side of the base 1, a first cylinder 11 threadedly mounted in the middle of the base 1, rotating rods mounted on both sides of the first cylinder 11 via couplings, a movable box 3 welded onto the rotating rods, a fourth drive motor 20 mounted on the rear side of the movable box 3, the output shaft of the fourth drive motor 20 extending into the interior of the movable box 3 via a coupling to mount a rotating disk, a rotating disk also mounted on the interior of the movable box 3 near the first mounting block 2 via a coupling, and a cutting strip 23 tensioned between the rotating disks.

[0021] The tilt adjustment function of the cutting strip 23 allows it to adapt to the cutting angle requirements of scrap steel of different shapes. The fourth drive motor 20 provides continuous cutting power, and the dual rotating disk design ensures high-speed and stable operation of the cutting belt.

[0022] A conveyor platform 4 is provided on one side of the base 1. A first conveyor belt 12 is provided on the base 1. A track 17 is provided on the conveyor platform 4. A platform 18 is provided between the first conveyor belt 12 and the track 17. A recessed groove is provided in the middle of the platform 18, and the recessed groove is located below the cutting strip 23.

[0023] A first electric telescopic mechanism 5 is threadedly installed on the side of the conveyor table 4 away from the base 1. The end of the first electric telescopic mechanism 5 extends to the top of the conveyor table 4 and is threadedly installed with a movable plate 6. The movable plate 6 has a cavity inside, and several spring dampers are evenly arranged in the cavity. A push plate 16 is installed through the spring dampers.

[0024] A fixing mechanism is provided on the platform 18. The fixing mechanism includes frames 8 set on both sides of the recessed groove of the platform 18. A second connecting strip 45 is welded between the two frames 8. A second cylinder 42 is threadedly installed on the bottom of the base 1 of the platform 18. The end of the second cylinder 42 is threadedly connected to the second connecting strip 45. A fixing box 9 is welded to the top of the frame 8. A second drive motor 46 is set on one side of the fixing box 9. The output shaft of the second drive motor 46 extends into the interior of the fixing box 9 and a lead screw is installed through a coupling. A movable frame 47 is threadedly connected to the lead screw. Several first locking blocks 44 are symmetrically arranged on the bottom inner side of the movable frame 47. A limit block 49 is welded to the bottom of the movable frame 47. Several springs are set on the limit block 49, and several pressure blocks 41 are welded through the springs. Second locking blocks 43 that are adapted to the first locking blocks 44 are integrally formed on the top two sides of the pressure blocks 41.

[0025] Furthermore, rubber anti-slip pads are provided on the upper surface of platform 18 and the lower surface of pressure block 41.

[0026] Furthermore, the second drive motor 46 drives the lead screw to rotate, which in turn moves the movable frame 47, thereby engaging the first locking block 44 with the second locking block 43, thus fixing the pressure block 41.

[0027] The activity box 3 is located above the frame 8 and has an extension plate 15, on which a first camera is installed.

[0028] The conveyor platform 4 is equipped with a track 17 inside. Conveyor frames 34 are movably arranged on both sides of the track 17 inside the conveyor platform 4. A second mounting block 26 is installed on the output end of the first cylinder 11. A first toothed plate 27 is provided on one side of the second mounting block 26. A first rotating shaft 25 and a second rotating shaft 30 are installed on both sides of the base 1 through a coupling. A first driven gear 28 and a second driven gear 29 are fitted on the first rotating shaft 25 and the second rotating shaft 30, respectively. The first driven gear 28 meshes with the first toothed plate 27.

[0029] Furthermore, top blocks 48 are placed on the conveyor frame 34, and scrap steel is placed between the top blocks 48.

[0030] The second rotating shaft 30 extends to the lower part of the conveyor frame 34 and is welded with a roller. A rack 31 is tensioned and fitted on the roller. Several third rotating rods and fourth rotating rods are also installed on both sides of the conveyor table 4 through couplings. A first movable block 33 is fitted on each of the third rotating rods and the fourth rotating rods. A transmission gear 32 is welded on the lower first movable block 33. The transmission gear 32 meshes with the rack 31. A second movable block 35 is hinged between the two first movable blocks 33. A third rotating shaft 37 is welded to one side of the second movable block 35. The third rotating shaft 37 is fitted with the conveyor frame 34.

[0031] Furthermore, a ratchet 36 is fitted onto the surface of the second driven gear 29, and the second rotating shaft 30 is welded and fixed to the ratchet 36. A spring-driven pawl 38 is installed on the surface of the ratchet 36.

[0032] The conveyor frame 34 drives the top block 48 to engage, performing intermittent cyclic conveying of scrap steel to ensure uniform size of the cut scrap steel, improving automation efficiency and the uniformity of subsequent processing. Simultaneously, through the cooperation of the ratchet 36 and pawl 38, when the first cylinder 11 drives the first toothed plate 27 to rise, the pawl 38 cannot lock the ratchet 36, thereby driving the second rotating shaft 30 to rotate, which in turn drives the rack 31 to rotate, thus driving the first movable block 33. When the first cylinder 11 drives the first toothed plate 27 to descend, it drives the first driven gear 28. When the first driven gear 28 rotates counterclockwise, the second driven gear 29 rotates clockwise, attempting to drive the second rotating shaft 30 to rotate clockwise. At this time, when the ratchet 36 attempts to rotate clockwise with the second rotating shaft 30, the tip of the pawl 38 will engage with the vertical surface of the ratchet teeth, preventing the ratchet 36 and the second rotating shaft 30 from rotating clockwise, thus facilitating the reset of the first cylinder 11. Although the first gear plate 27 is moving, the first driven gear 28 is rotating counterclockwise, and the second driven gear 29 is attempting to rotate clockwise, the second rotating shaft 30 is locked by the pawl 38 and cannot rotate.

[0033] A third drive motor 19 is threadedly mounted on the first mounting block 2. The output shaft of the third drive motor 19 extends into the first mounting block 2 and is fitted with a first synchronous belt 21. A rotating ring 22 is mounted on the bottom inner side of the first mounting block 2 via a coupling. The first synchronous belt 21 and the rotating ring 22 are tensioned together. A first rotating rod 50 is mounted on the end of the rotating ring 22 via a coupling. A rotating plate 39 is fitted on the first rotating rod 50 and is threadedly fixed to the movable box 3.

[0034] A groove 10 is provided on the base 1, and a first conveyor belt 12 is installed above the groove 10. Vertical plates 24 are threadedly fixed on both sides of the base 1 at the groove 10. A first drive motor 7 is threadedly installed on one side of the vertical plate 24. The first drive motor 7 is used to drive the first conveyor belt 12. A first connecting strip 14 is hinged between the vertical plates 24. Several nozzles are installed on the lower surface of the first connecting strip 14. A water tank 40 is fixedly provided on one side of the base 1. A water pump is provided in the water tank 40. A connecting pipe 13 is connected to the water pump. The connecting pipe 13 extends into the interior of the first connecting strip 14 and is connected to the nozzle pipe.

[0035] Working principle: When in use, this device places scrap steel on the track 17 of the conveyor platform 4, with both ends of the scrap steel placed on the top block 48. The first electric telescopic mechanism 5 drives the movable plate 6 and the push plate 16 to push the scrap steel forward through the spring damper. At the same time, the first cylinder 11 drives the first toothed plate 27 to rise, and the first driven gear 28 rotates clockwise, which in turn drives the second rotating shaft 30 to rotate counterclockwise, further driving the rack 31 to rotate, thereby driving the first movable block 33 to drive the conveyor frame 34 to perform continuous progressive action. In cooperation with the first electric telescopic mechanism 5, the scrap steel is sent into the platform 18. When the scrap steel is moved onto the platform 18, the second cylinder 42 drives the second connecting bar 45 to move down, causing the frame 8 and the fixed box 9 connected by the second connecting bar 45 to move down. The pressure block 41 below the fixed box 9 comes into contact with the scrap steel, and the second drive motor 46 is started. The lead screw drives the movable frame 47 to move forward, so that the first locking block 44 inside the movable frame 47 is locked with the second locking block 43 set on the top of the pressure block 41, thereby fixing the scrap steel. The third drive motor 19 drives the first synchronous belt 21 to drive the rotating ring 22 to rotate. The rotating ring 22 rotates at the same time, driving the first rotating rod 50 to rotate, which in turn drives the rotating plate 39 to drive the movable box 3 to rotate, thereby realizing the position adjustment of the cutting strip 23 and starting the cutting process of scrap steel. After the cutting is completed, the second cylinder 42 is reset, and the first cylinder 11 and the first electric telescopic machine 5 drive the scrap steel to feed at equal distances to carry out the cutting operation. After the overall cutting is completed, the first electric telescopic machine 5 resets, the first cylinder 11 drives the first toothed plate 27 to descend, drives the first driven gear 28 to rotate counterclockwise, and the second driven gear 29 to rotate clockwise, attempting to drive the second rotating shaft 30 to rotate clockwise. At this time, when the ratchet 36 tries to rotate clockwise with the second rotating shaft 30, the tip of the pawl 38 will get stuck in the vertical surface of the ratchet teeth, preventing the ratchet 36 and the second rotating shaft 30 from rotating clockwise. Although the first toothed plate 27 is moving, the first driven gear 28 is rotating counterclockwise, and the second driven gear 29 is trying to rotate clockwise, the second rotating shaft 30 cannot rotate because it is locked by the pawl 38. Therefore, the rack 31 installed on the second rotating shaft 30 also remains stationary and does not rotate. The conveyor frame 34 does not move, and the first cylinder 11 resets normally. After cutting, the scrap steel is conveyed by the first conveyor belt 12 and sprayed with rust remover through the top first connecting strip 14.

[0036] In this embodiment, because the shapes and thicknesses of the scrap steel are different, there are differences in how the scrap steel is fixed.

[0037] When cutting large but easily deformable thin sheet scrap such as car shells and home appliance panels, the scrap steel is placed on the top block 48. The first electric telescopic machine 5 drives the push plate 16 to push the bottom of the scrap steel. When the scrap steel moves to the platform 18, the two fixed boxes 9 on both sides, under the force of the second cylinder 42, make the bottom pressure block 41 contact the scrap steel. The pressure block 41 flattens the thin plate, which makes it easy to completely fix the two sides of the cutting point. After the pressure block 41 is stable, the second drive motor 46 drives the movable frame 47 to move, so that the first locking block 44 and the second locking block 43 are locked together. At this time, the cutting strip 23 cuts vertically downward. The above operation is repeated to obtain scrap steel of equal length.

[0038] During the process of fixing the irregularly shaped parts, the second cylinder 42 drives the fixing box 9 to move down, so that the pressure block 41 comes into contact with the irregularly shaped parts. Because the irregularly shaped parts are of different shapes and are irregular in shape, and the surface is uneven, after the pressure block 41 contacts the surface of the irregularly shaped parts, the second cylinder 42 continues to apply a pulling force, which drives the pressure block 41 to further contact the surface of the irregularly shaped parts. Because the surface height of the irregularly shaped parts is different, the height of each pressure block 41 is also different. When the spring above the pressure block 41 is stable, the second drive motor 46 drives the movable frame 47 to move, so that the first locking block 44 and the second locking block 43 are locked together. At this time, the positions of the different pressure blocks 41 are fluctuating, and the pressure generated by each pressure block 41 on the spring is different, which makes it easier to limit the irregularly shaped parts. At the same time, the cutting strip 23 cuts vertically downward.

[0039] During the cutting process described above, the first cylinder 11 drives the scrap steel to move toward one side of the platform 18 at the same speed. Therefore, the width of the cut scrap steel segments is also consistent, which facilitates subsequent collection and transportation for the next processing step.

[0040] When cutting thick-walled pipes, cylindrical pipes are difficult to fix. Therefore, a V-shaped alloy bracket is installed on the top block 48. After the pipe is inserted, the first cylinder 11 drives the rack 31 to rotate stepwise and move towards the cutting strip 23. When it moves to the platform 18, the second cylinder 42 drives the fixing box 9 to move down. When the pressure block 41 contacts the pipe wall, the second drive motor 46 is started to drive the movable frame 47 to move, so that the first clamping block 44 and the second clamping block 43 are locked together, limiting the pipe. The cutting strip 23 then cuts vertically downward. Furthermore, if the length of the cutting bar 23 is less than the thickness of the pipe, the cutting will not be complete in one go. In this case, after cutting to the depth of the cutting bar 23, the fourth drive motor 20 is turned off, and the height of the cutting bar 23 is adjusted by the saw height adjustment mechanism (not shown in the figure) so that the cutting bar 23 is sufficient to cut the pipe. After the cutting is completed, it is reset.

[0041] Meanwhile, during the cutting of thick-walled pipes, the third drive motor 19 drives the first synchronous belt 21 to drive the rotating ring 22 to rotate. The rotating ring 22 rotates while driving the first rotating rod 50 to rotate, which in turn drives the rotating plate 39 to drive the movable box 3 to rotate, adjusting the cutting strip 23 to 20° and cutting the pipe at an angle, thereby further improving the service life of the cutting strip 23.

[0042] Example 2: Based on Example 1, during use, the staff found that some thin-plate scrap steel, such as vehicle frames and irregularly shaped parts, could not be fully in contact with the platform 18 during the cutting process, as the scrap steel was only fixed by the pressure block 41 set on the fixed box 9. This could lead to wobbling and a certain cutting risk.

[0043] Please refer to Figures 13-15 Based on Embodiment 1, an extrusion platform 55 is installed in the internal thread of the conveyor platform 4. The extrusion platform 55 is set to abut against the track 17, and the width of the extrusion platform 55 is consistent with that of the track 17.

[0044] Furthermore, movable grooves 51 are provided on both sides of the conveyor table 4. Sliding blocks 52 are slidably arranged in the movable grooves 51. An L-shaped plate 53 is welded and installed on the sliding block 52. The other end of the L-shaped plate 53 extends to the top of the conveyor table 4 and is installed with an extrusion box 54. The interior of the extrusion box 54 is hollow. A limit plate 59 is welded to one side of the interior of the extrusion box 54. A connecting rod 62 is hinged to the top of the limit plate 59, and a first rotating disk 60 is hinged to the connecting rod 62. A fifth rotating rod is installed inside the extrusion box 54 through a coupling. A second rotating disk 61 is welded to the end of the second rotating rod. A vertical rod 57 is movably arranged between the first rotating disk 60 and the second rotating disk 61. A drop hammer 56 is welded to the outside of the extrusion box 54 through the vertical rod 57. A second electric telescopic mechanism 58 is provided on the bottom inner side of the extrusion box 54. The end of the second electric telescopic mechanism 58 is welded to the connecting rod 62.

[0045] Furthermore, a second toothed plate is provided on both sides of the vertical rod 57, and gear grooves that are adapted to the second toothed plate are provided on the opposite surfaces of the first rotating disk 60 and the second rotating disk 61.

[0046] The second electric telescopic mechanism 58 drives the connecting rod 62 to deflect upward, which in turn causes the first rotating disk 60 to come into contact with the vertical rod 57. Then, through gear transmission, the vertical rod 57 is driven to rise, causing the drop hammer 56 to move upward. When it is necessary to compress the thin plate-shaped scrap steel on the extrusion table 55, the second electric telescopic mechanism 58 retracts, so that the force on one side of the vertical rod 57 disappears. Under the influence of gravity, the drop hammer 56 impacts the scrap steel and compresses the scrap steel into a flat plate shape, which is convenient for subsequent fixing operations.

[0047] Furthermore, during the extrusion operation of scrap steel, the maximum thickness of the scrap steel before entering the extrusion table 55 is A, the maximum thickness after extrusion is B, the thickness of the scrap steel after cutting is C, and the length of the cutting bar 23 is D.

[0048] When B > D, the effective cutting depth D of the cutting bar 23 is less than the maximum thickness B of the extruded scrap steel. The cutting bar 23 cannot completely penetrate the scrap steel material in one cut, resulting in incomplete cutting. At this time, the machine needs to be stopped to adjust the height and position of the cutting bar 23 and perform a second cut, which makes it take a long time for this section of scrap steel to be cut.

[0049] Meanwhile, during the cutting process, the fourth drive motor 20 drives the cutting strip 23 to run at high speed, but the cutting resistance increases with the thickness. If B > D, the cutting strip 23 is prone to jamming, overheating, or accelerated wear, or even breakage. Therefore, it is necessary to stop the machine for maintenance after the cutting is completed.

[0050] When B < D and the value of B is too small, the thickness B after extrusion is much smaller than the length D of the cutting strip 23. The cutting depth of the cutting strip 23 is excessive. At this time, the pressure block 41 may not be firmly fixed to the scrap steel and may shake, causing vibration or trembling during the cutting process, affecting the cutting accuracy and surface quality. At this time, the edge of the scrap steel after cutting is deformed, resulting in a non-straight cut or a wavy cut surface, which leads to the height C after cutting being inconsistent with B.

[0051] Furthermore, second cameras are installed on both sides of the conveyor table 4, facing the extrusion table 55. The height B of the scrap steel after extrusion is observed through the second cameras. If B is much smaller than D, the scrap steel is removed, folded and compressed into blocks by an external hydraulic shearing machine, and then placed on the track 17 for subsequent cutting.

[0052] When CB > 1mm, the thickness C of the cut irregular-shaped scrap steel strip deviates too much from the thickness B after extrusion. At this time, the video of the part being extruded by the drop hammer 56 on the extrusion table 55 is analyzed by the camera. If a height difference is observed at the drop hammer 56, it proves that the part is not completely extruded. After cutting, the local unflattened area causes C to fluctuate. Furthermore, uneven pressure applied by the pressure block 41 causes slight movement of the scrap steel during cutting, resulting in a tilted cutting surface and a deviation in the C value. The second cylinder 42 increases the output power to fix the scrap steel of the irregularly shaped part and prevent it from shaking.

[0053] When A≈B, after repeated operation of the drop hammer 56, the camera detects that the initial thickness of the scrap steel does not change significantly, indicating that the scrap steel is too hard or is spring steel. At this time, the drop hammer 56 is driven to rise by the second electric telescopic machine 58. By adding a conical alloy pressure head to the bottom of the drop hammer 56, and by repeatedly dropping the drop hammer 56 to break through the scrap steel, after B reaches the cuttable value, it is sent to the cutting bar 23 for cutting through the conveyor frame 34.

[0054] The above methods are used to cut thin-plate scrap steel and irregularly shaped scrap steel, and to extrude the scrap steel to reduce the thickness during cutting, so that the cutting strip 23 can perform the cutting operation better.
