Description

Technical Field

[0001] This application relates to the field of steel plate cutting technology, and in particular to a cutting device for the production and processing of galvanized steel plates. Background Technology

[0002] With the development of modern industry, galvanized steel sheets are increasingly widely used in various fields, such as construction, automobiles, and home appliances. Galvanized steel sheets are made by coating the surface of steel sheets with a layer of metallic zinc to prevent corrosion, providing an economical and effective anti-corrosion solution and extending service life. The production and processing technology of galvanized steel sheets is also receiving increasing attention. Cutting is an essential step in the production and processing of galvanized steel sheets, requiring cutting equipment to cut them to the actual dimensions needed for application to meet user requirements.

[0003] The existing technology still has the following problems:

[0004] 1. Most existing cutting devices rely on manual feeding, which wastes manpower and has low efficiency. The few cutting devices that use feeding mechanisms can only feed boards of fixed specifications and have a low error tolerance.

[0005] 2. Existing cutting equipment usually cuts galvanized sheets by marking them and then manually pushing them. Measuring and marking the galvanized sheets is time-consuming and results in low cutting efficiency, while manual pushing can easily cause unnecessary injury to workers.

[0006] 3. The cutting device generates a lot of debris during cutting. The flying debris can easily injure the workers. If the debris is not cleaned up in time and accumulates on the cutting equipment, it will cause the galvanized sheet to tilt on the equipment, thus affecting the cutting accuracy of the sheet.

[0018] The technical solution provided in this application has at least the following technical effects or advantages:

[0019] 1. By adopting a feeding assembly, the invention effectively solves the problem that most existing cutting devices rely on manual feeding, which wastes manpower and has low efficiency. Furthermore, the few cutting devices that use feeding mechanisms to feed sheet metal can only feed sheet metal of fixed specifications, resulting in a low error tolerance. This invention uses a feeding assembly to feed galvanized steel sheets of different specifications, avoiding the waste of manual feeding and improving work efficiency. The feeding mechanism can be adjusted according to the thickness specifications of the galvanized steel sheet, increasing the error tolerance of the feeding mechanism.

[0020] 2. By adopting a fixed-distance conveying component, this invention effectively solves the problem that existing cutting devices typically involve marking the galvanized sheet and then manually pushing it for cutting. Measuring and marking the galvanized sheet wastes time and leads to low cutting efficiency. Furthermore, manual pushing can easily cause unnecessary injury to workers. This invention avoids wasting cutting time through manual measurement using a fixed-distance conveying component, while also preventing accidental injury to workers from manual pushing. The moving distance can be adjusted, allowing the cutting distance to be adjusted according to actual needs, achieving precise cutting.

[0021] 3. Due to the use of a cutting component, the problem of a large amount of debris generated during the cutting process is effectively solved. The flying debris can easily injure workers. If the debris is not cleaned up in time and accumulates on the cutting equipment, it will cause the galvanized sheet to tilt on the equipment, thereby affecting the cutting accuracy of the sheet. This invention can prevent the flying debris through the cutting component, and at the same time, it can clean up the debris in a concentrated manner to avoid the accumulated debris affecting the cutting accuracy of the galvanized sheet.

[0040] To address the waste of manpower in manual material loading, this invention uses a feeding assembly to load galvanized steel sheets of different specifications, avoiding the waste of effort in manual material loading. Regarding the common practice of marking galvanized sheets and then manually pushing them for cutting, this invention uses a fixed-distance conveying assembly to avoid wasting cutting time on manual measurement, while also preventing accidental injury to workers from manual pushing. Furthermore, to address the issue of large amounts of debris generated during cutting, which could easily injure workers, this invention uses a cutting assembly to prevent debris from flying.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] Example 1

[0043] Please see Figure 1As shown, a cutting device for galvanized steel sheet production and processing includes a workbench 1. A conveyor wheel 2 is rotatably connected to the inner wall of the upper surface of the workbench 1. A drive motor is installed in the inner cavity of the workbench 1 to drive the conveyor wheel 2 to rotate, facilitating the conveying of the steel sheet workpiece 4. A feeding assembly 3 is fixedly installed at one end of the workbench 1. The steel sheet workpiece 4 is placed in the inner cavity of the feeding assembly 3. A fixed-distance conveying assembly 5 is installed in the inner cavity of the workbench 1. A second chute 6 is opened on the upper surface of the workbench 1. A cutting assembly 7 is installed in the inner cavity of the workbench 1. A dust guide groove 8 is opened on the upper surface of the workbench 1. The feeding assembly 3 evenly feeds the steel sheet workpiece 4. The fixed-distance conveying assembly 5, in conjunction with the second chute 6, is used to convey and cut the steel sheet workpiece 4 at a fixed distance. The cutting assembly 7 is used to cut the steel sheet workpiece 4 and collect and clean the debris. The dust guide groove 8 is used to guide the debris.

[0044] Please see Figure 2 and Figure 3 As shown, the feeding assembly 3 includes a storage rack 31, a feeding rack 32 fixedly installed at the bottom of the storage rack 31, a cylinder 33 fixedly installed in the inner cavity of the feeding rack 32, a piston rod 34 slidably connected to the inner cavity of the cylinder 33, a first adjusting mechanism 35 slidably connected to the inner cavity of the feeding rack 32, a second adjusting mechanism 36 provided on the side of the storage rack 31 near the worktable 1, and an adjusting cavity 37 opened on the side of the storage rack 31 near the worktable 1. The operation of the cylinder 33 drives the piston rod 34 to move, the movement of the piston rod 34 drives the first adjusting mechanism 35 to move, and the movement of the first adjusting mechanism 35 drives the lowest layer of steel plate processing parts 4 to go out from the bottom of the storage rack 31 and reach the conveyor wheel 2 for the next step of cutting. The height of the first adjusting mechanism 35 can be adjusted to facilitate the pushing and discharging of steel plate processing parts 4 of different thicknesses. At the same time, by adjusting the second adjusting mechanism 36, the gap between the adjusting cavity 37 and the second adjusting mechanism 36 can allow the steel plate processing parts 4 to pass through.

[0045] Please see Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the first adjusting mechanism 35 includes a slide 351. A fixing block 352 is fixedly installed at one end of the slide 351. A first insert rod 353 is inserted into the inner cavity of the fixing block 352. A first spring 354 is sleeved on the outer surface of the first insert rod 353. A first fixing ring 355 is fixedly installed on the outer surface of the first insert rod 353. The first spring 354 is located between the fixing block 352 and the first fixing ring 355. An adjusting cylinder 356 is slidably connected to the inner cavity of the slide 351. A first insertion hole 357 is opened on the outer surface of the adjusting cylinder 356. There are multiple first insertion holes 357. A telescopic rod 358 is slidably connected to the inner cavity of the adjusting cylinder 356. A second spring 359 is fixedly connected to the bottom end of the adjusting cylinder 356. The bottom end of the telescopic rod 358 and the second spring 359 are also fixedly connected. 9. Fixed connection: The first insertion rod 353 and the first insertion hole 357 are inserted into each other. The bottom end of the slide 351 and the piston rod 34 are fixedly connected. The second adjustment mechanism 36 includes a shielding strip 361. A first connecting strip 362 is movably connected to the upper surface of the shielding strip 361. There are two first connecting strips 362, and they are symmetrically distributed about the middle part of the shielding strip 361. A first moving block 363 is movably connected to the end of the first connecting strip 362 away from the shielding strip 361. A first threaded rod 364 is provided in the inner cavity of the first moving block 363. The first threaded rod 364 and the first moving block 363 are connected by threads, and the threads at both ends of the first threaded rod 364 are in opposite directions. The first moving block 363 is slidably connected to the storage rack 31. The threaded rod 364 and the storage rack 31 are rotatably connected, and the shielding strip 361 and the inner cavity of the adjusting cavity 37 are slidably connected. There are two first moving blocks 363, which are symmetrically distributed about the middle part of the first threaded rod 364. When the thickness of the steel plate processing part 4 is different, that is, when the specifications are different, the first insert rod 353 is pulled to disengage the first insert rod 353 from the first insertion hole 357. At this time, the adjusting cylinder 356 is moved to move in the inner cavity of the slide 351. When the appropriate height is reached, the first insert rod 353 is released and the first fixing ring 355 is squeezed under the elastic force of the first spring 354, so that the first insert rod 353 is engaged with the first insertion hole 357 again. Thus, the overall height of the adjusting cylinder 356 and the telescopic rod 358 changes. The telescopic rod 358 is used... To push the steel plate workpiece 4, a second spring 359 is installed at the bottom of the telescopic rod 358 to prevent excessive rigidity between the telescopic rod 358 and the adjusting cylinder 356, thus avoiding scratches on the bottom steel plate workpiece 4 by the telescopic rod 358 during reset after feeding. During reset, the telescopic rod 358 compresses the second spring 359 under the weight of the steel plate workpiece 4, causing the telescopic rod 358 to contract and reduce friction on the steel plate workpiece 4. Simultaneously, by rotating the first threaded rod 364, the first moving block 363 moves on the first threaded rod 364, causing a change in the inclination of the first connecting strip 362. This, in turn, causes a change in the height of the blocking strip 361, thereby changing the gap formed by the blocking strip 361 and the bottom of the adjusting cavity 37.When the first adjusting mechanism 35 pushes material, it can only pass through one piece of steel plate 4. The second adjusting mechanism 36 can be adjusted according to the thickness of the steel plate 4.

[0046] Please see Figure 8 , Figure 9 and Figure 10 As shown, the fixed-distance conveying assembly 5 includes a connecting plate 51. A fixed frame 52 is fixedly mounted on the upper surface of the connecting plate 51. A first motor 53 is fixedly mounted on the outer surface of the fixed frame 52. A turntable 54 is rotatably connected to the outer surface of the fixed frame 52. The outer surface of the turntable 54 is sleeved with the output end of the first motor 53. An adjusting track 55 is fixedly mounted on the outer surface of the turntable 54. The inner cavity of the adjusting track 55 has a second insertion hole 56. There are multiple second insertion holes 56, which are evenly distributed from the center of the turntable 54 to the edge of the turntable 54. In this way, each time the third adjusting mechanism 59 is engaged with different second insertion holes 56, the distance that the moving mechanism 58 pushes the steel plate processing part 4 can be changed. The two ends of the fixed frame 52 are fixedly mounted with... The limiting block 57 has a sliding connection to a moving mechanism 58, and the moving mechanism 58 has a sliding connection to a third adjusting mechanism 59. When the steel plate workpiece 4 is being cut at a fixed distance, the operation of the first motor 53 drives the turntable 54 to rotate. The rotation of the turntable 54 drives the adjusting track 55 to rotate. The rotation of the adjusting track 55 drives the third adjusting mechanism 59 to rotate. The rotation of the third adjusting mechanism 59 drives the moving mechanism 58 to move on the limiting block 57. Since the radius of the third adjusting mechanism 59 is fixed when it rotates, the length of half a turn of the third adjusting mechanism 59 is equal to the length of the moving mechanism 58. The moving mechanism 58 pushes the steel plate workpiece 4 to move. The continued rotation of the third adjusting mechanism 59 is used for resetting.

[0047] Please see Figure 9 , Figure 10 and Figure 11As shown, the moving mechanism 58 includes a moving slide rail 581, with connecting rods 582 fixedly installed at both ends of the moving slide rail 581. Second threaded rods 583 are rotatably connected to both ends of the moving slide rail 581. A first sliding groove 584 is formed on the upper surface of the connecting rods 582. A second moving block 585 is sleeved on the outer surface of the second threaded rod 583. A buffer seat 586 is fixedly installed at the upper end of the second moving block 585. A connecting frame 587 is slidably connected to the inner cavity of the buffer seat 586. A locking block 588 is provided on the upper surface of the connecting frame 587. Block 585 and the first slide groove 584 are slidably connected. The second moving block 585 and the second threaded rod 583 are connected by threads. The moving sleeve 581 and the third adjusting mechanism 59 are slidably connected. The inner cavity of the buffer seat 586 is provided with a third spring. The bottom end of the connecting frame 587 is elastically connected to the third spring. The top of the locking block 588 is inclined, and the lower side of the inclination is located on the side closer to the conveyor wheel 2. During the rotation of the third adjusting mechanism 59, it moves on the moving sleeve 581, thereby driving the moving sleeve 581 to move back and forth. The movement of the connecting rod 582 causes the second moving block 585 to move, which in turn causes the locking block 588 to move. This, in turn, causes the locking block 588 to push the steel plate workpiece 4 to move. The third spring inside the buffer seat 586 is designed to press the locking block 588 down into the inner cavity of the second slide groove 6 when it encounters the inclined surface of the locking block 588 during the movement of the steel plate workpiece 4. After the steel plate workpiece 4 passes the locking block 588, the third spring's force resets the locking block 588, thus allowing the steel plate workpiece 4 to move. The end of the plate workpiece 4 is attached to the clamping block 588. Finally, the plate workpiece 4 is precisely cut by the equidistant movement of the clamping block 588. By rotating the second threaded rod 583, the second moving block 585 can be driven to move in the inner cavity of the first slide groove 584. That is, the initial position of the second moving block 585 changes, so that one end of the plate workpiece 4 contacts the clamping block 588 and the other end is attached to the cutting blade 75. This makes it easy to calculate the moving distance and achieve precise cutting. The initial position can be adjusted according to the size of the second moving block 585.

[0048] Please see Figure 9 , Figure 12 and Figure 13As shown, the third adjustment mechanism 59 includes a first slider 591. A connecting cylinder 592 is fixedly installed on the outer surface of the first slider 591. A spring rod 593 is slidably connected to the inner cavity of the connecting cylinder 592. A limit ring 594 is fixedly installed at the bottom end of the spring rod 593. A second insertion rod 595 is fixedly installed at one end of the limit ring 594. The second insertion rod 595 is slidably connected to the first slider 591 and the connecting cylinder 592. The second insertion rod 595 is inserted into the second insertion hole 56. A fourth spring 596 is provided on the side of the limit ring 594 away from the second insertion rod 595. The end of the fourth spring 596 away from the limit ring 594 is fixedly connected to the inner wall of the connecting cylinder 592. A hand lever 597 is fixedly installed on the outer surface of the spring rod 593. The connecting cylinder 592 and the moving sleeve 581 are slidably connected. By adjusting the third adjustment mechanism 59... The position in the adjusting track 55 is adjusted to change the radius of rotation of the third adjusting mechanism 59, thereby changing the moving distance of the moving mechanism 58. The distance can be controlled in conjunction with the rotation angle of the turntable 54. The distance by which the moving mechanism 58 pushes the steel plate processing part 4 can be adjusted according to the cutting needs. By pulling the lever 597, the elastic rod 593 moves in the inner cavity of the connecting cylinder 592. At this time, the elastic rod 593 drives the limiting ring 594 to squeeze the fourth spring 596, causing the second insert 595 on the limiting ring 594 to retract. Thus, the second insert 595 disengages from the second insertion hole 56, and the position of the first slider 591 on the adjusting track 55 is moved. When the appropriate position is reached, the lever 597 is released to allow the second insert 595 to engage with the second insertion hole 56, thus fixing the third adjusting mechanism 59 as a whole and fixing the radius of motion.

The operation of the second motor 72 drives the first lead screw 71 to rotate, and the rotation of the first lead screw 71 drives the moving frame 73 to move on the first lead screw 71. The operation of the third motor 76 drives the cutting blade 75 to rotate. The cutting blade 75 is used to cut the steel plate workpiece 4. The dust cover 74 is used to prevent the debris from flying during cutting. At the same time, the rotation of the first lead screw 71 drives the cleaning mechanism 77 to clean the debris, and the dust removal mechanism 78 is used to collect the debris and remove it periodically.

[0051] Please see Figure 15 As shown, the cleaning mechanism 77 includes a belt 771, which is sleeved with a first lead screw 71. A second lead screw 772 is sleeved at the bottom end of the belt 771. The second lead screw 772 is rotatably connected to the inner wall of the worktable 1. A second slider 773 is sleeved on the outer surface of the second lead screw 772. The second lead screw 772 and the second slider 773 are connected by threads. A fixing strip 774 is fixedly installed at the top end of the second slider 773. A cleaning brush 775 is fixedly installed at the top end of the fixing strip 774. The dust guide groove 8 is horizontal at both ends and slopes downward near the middle. The middle part is hollowed out. The cleaning brush 775 and the horizontal end of the dust guide groove 8 are tightly fitted. The fixing strip 774 and the dust guide groove 8 are slidably connected. The second slider 771... 3 is slidably connected to the inner cavity of the workbench 1, and the belt 771 is movably connected to the inner cavity of the workbench 1. The rotation of the first lead screw 71 drives the belt 771 to rotate, and the rotation of the belt 771 drives the second lead screw 772 to rotate. The rotation of the second lead screw 772 drives the second slider 773 to move on the second lead screw 772. At this time, the movement of the second slider 773 drives the fixed bar 774 to move. The movement of the fixed bar 774 drives the cleaning brush 775 to move above the dust guide groove 8. The debris blocked by the dust cover 74 falls into the dust guide groove 8. The cleaning brush 775 pushes and cleans the debris on the dust guide groove 8 onto the inclined surface of the dust guide groove 8. The debris on the inclined surface rolls down to the dust removal mechanism 78 for collection.

[0052] Please see Figure 14 , Figure 16 and Figure 17As shown, the dust removal mechanism 78 includes a dust collection box 781. A second connecting bar 782 is fixedly connected to one end of the dust collection box 781. A hand lever 783 is fixedly connected to the end of the second connecting bar 782 away from the dust collection box 781. A third insert rod 784 is inserted into the inner cavity of the second connecting bar 782. A second fixing ring 785 is fixedly installed on the outer surface of the third insert rod 784. A fifth spring 786 is sleeved on the outer surface of the third insert rod 784, located between the second connecting bar 782 and the second fixing ring 785. A limit hole is provided in the inner cavity of the worktable 1. The third insert rod 784 and the limit hole of the worktable 1... With the positioning hole engaged, the dust collection box 781 is located at the bottom of the middle part of the dust guide groove 8 and below the second lead screw 772. The dust collection box 781 is used to collect fallen debris. By engaging the third insert rod 784 with the limiting hole, the second connecting strip 782 is fixed inside the workbench 1, allowing the dust collection box 781 to collect the debris falling from the dust guide groove 8. When the dust collection box 781 is almost full, pull the third insert rod 784 to compress the second fixing ring 785 and the fifth spring 786. At this time, the third insert rod 784 and the limiting hole are disengaged. Pulling the lever 783 allows the dust collection box 781 to be removed for cleaning of debris.

[0053] In summary, the operation of cylinder 33 drives the lowest layer of steel plate workpiece 4 out from the bottom of storage rack 31 and into conveyor wheel 2 for further cutting. Pulling the first insertion rod 353 disengages it from the first insertion hole 357. At this time, the adjusting cylinder 356 moves within the slide 351. When the appropriate height is reached, the first insertion rod 353 is released, causing a change in the overall height of the adjusting cylinder 356 and telescopic rod 358. Simultaneously, rotating the first threaded rod 364 changes the height of the blocking strip 361, thus changing the gap formed by the blocking strip 361 and the bottom of the adjusting cavity 37. This allows only one steel plate workpiece 4 to pass through when the first adjusting mechanism 35 pushes the material. The working moving mechanism 58 of the first motor 53 moves on the limit block 57. Since the radius of the third adjusting mechanism 59 is fixed when rotating, the length of half a turn of the third adjusting mechanism 59 is equal to the length of movement of the moving mechanism 58. The moving mechanism 58 pushes the steel plate workpiece 4 to move. The third adjusting mechanism 59... Continued rotation is used for resetting. During the rotation of the third adjustment mechanism 59, the moving sleeve 581 moves, thereby driving the moving sleeve 581 to move back and forth. The movement of the moving sleeve 581 drives the locking block 588 to move, thereby pushing the steel plate workpiece 4 to move. The steel plate workpiece 4 is precisely cut by the equidistant movement of the locking block 588. By adjusting the position of the third adjustment mechanism 59 in the adjustment track 55, the rotation radius of the third adjustment mechanism 59 is changed, thereby changing the movement distance of the moving mechanism 58. The operation of the second motor 72 drives the cutting blade 75 to rotate. The cutting blade 75 is used to cut the steel plate workpiece 4. The dust cover 74 is used to prevent debris from splashing during cutting. The rotation of the first lead screw 71 drives the cleaning brush 775 to move above the dust guide groove 8. The debris blocked by the dust cover 74 falls into the dust guide groove 8. The cleaning brush 775 pushes and cleans the debris on the dust guide groove 8 onto the inclined surface of the dust guide groove 8. The debris on the inclined surface rolls down to the dust removal mechanism 78 for collection.
