Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a sawing device for a CNC steel plate milling machine. Background Technology
[0002] In the metal processing field, CNC steel plate sawing and milling machines are commonly used equipment for sawing and milling steel plates to meet the needs of various industrial production. However, existing CNC steel plate sawing and milling machines face many problems that urgently need to be solved when processing longer steel plates.
[0003] When processing long steel plates, the parts outside the support range of the workbench lack sufficient support and will bend downwards under their own weight. This deformation not only causes the surface of the steel plate to be uneven, affecting the accuracy of subsequent processing, but may also cause additional stress to be generated in the steel plate during sawing or milling, further aggravating the degree of deformation. In severe cases, it may even make the processed steel plate unable to meet the requirements, resulting in material waste and increased production costs.
[0004] Traditional CNC steel plate sawing and milling machines typically have a fixed support structure. To accommodate the processing of longer steel plates, a large working space needs to be reserved. However, in actual production, workshop space is often limited. The fixed support structure still occupies a lot of space when not in use, resulting in low workshop space utilization and increased operating costs for enterprises. Moreover, for some processing sites with limited space, it may not be possible to install sawing and milling machines with traditional large support structures, thus limiting the application range of the equipment.
[0005] In addition, after the long steel plate is sawed, it needs to be moved to the processing area for subsequent milling and other processing steps. During this process, the long steel plate itself is quite long, and even slight external force interference during the movement may cause the steel plate to deviate. Existing sawing and milling machines lack effective guiding and fixing devices during the movement of long steel plates, and cannot flexibly adjust for long steel plates of different widths, resulting in deviations in processing dimensions, affecting processing quality, and reducing the product qualification rate.
[0006] Therefore, it is necessary to provide a new CNC steel plate milling machine sawing device to solve the above-mentioned technical problems. Utility Model Content
[0007] To solve the above-mentioned technical problems, this utility model provides a sawing device for a CNC steel plate milling machine.

A saw blade is installed inside the sawing and milling machine body. A top rod is installed inside the sawing and milling machine body near the saw blade. A worktable is installed inside the sawing and milling machine body. Support rods are symmetrically arranged at equal intervals on one side of the worktable. A support plate is installed on the top of each set of support rods. A telescopic mechanism is installed between the worktable and the support rods. The telescopic mechanism drives several support rods to extend to one side of the worktable to support longer steel plates. A baffle is installed on the side wall of the several support plates that is farthest from the worktable. Positioning plates are symmetrically installed on the top of the end of the worktable near the several support plates. A positioning component is installed between the worktable and the positioning plates. The positioning component drives two positioning plates to move closer to each other to fix steel plates of different widths.
[0009] Preferably, the telescopic mechanism includes a hydraulic push rod and a crossbar. The hydraulic push rod is fixedly connected to one end of the worktable. A cross component is provided between every two adjacent support rods. A crossbar is rotatably connected between every two symmetrical cross components. The output end of the hydraulic push rod is fixedly connected to one of the crossbars closest to the worktable.
[0010] Preferably, the cross assembly includes: a first link and a second link. Both ends of the plurality of support rods are slidably connected to collars. The collar of each pair of adjacent support rods, near the top of the worktable, is rotatably connected to the first link. The bottom end of the first link is rotatably connected to the collar of each pair of adjacent support rods, away from the bottom of the worktable. The middle of the first link is rotatably connected to the second link. The top end of the second link is rotatably connected to the collar of each pair of adjacent support rods, away from the top of the worktable. The bottom end of the second link is rotatably connected to the collar of each pair of adjacent support rods, near the bottom of the worktable.
[0011] Preferably, the positioning component includes a bidirectional threaded rod and a threaded slider. A groove is provided on the top of the worktable, and the inner wall of the groove is rotatably connected to the bidirectional threaded rod. Both ends of the bidirectional threaded rod are threadedly connected to threaded sliders, and the top ends of the threaded sliders are respectively fixedly connected to the corresponding positioning plates.
[0012] Preferably, the two positioning plates are equidistantly rotatably connected to circular rollers inside, and one end of the bidirectional threaded rod extends out of the outer wall of the workbench and is fixedly connected to a crank handle.
[0013] Preferably, a slide cylinder is symmetrically fixedly connected to one end of the worktable, and a slide rod is slidably connected to the inner wall of each slide cylinder. One end of the slide rod is fixedly connected to the middle of a group of support rods near the baffle.
[0014] Preferably, the two ends of the group of support rods closest to the worktable are fixedly connected to the worktable, and the bottoms of the group of support rods furthest from the worktable are equipped with rollers.
[0015] Compared with related technologies, the CNC steel plate sawing and milling machine sawing device provided by this utility model has the following beneficial effects:
[0016] By extending the support rod and support plate through the telescopic mechanism, when processing long steel plates, the support plate can provide sufficient support for the part that exceeds the worktable, preventing the steel plate from bending and deforming downwards due to its own weight. This keeps the surface of the steel plate flat, reduces processing accuracy errors caused by deformation, improves the quality of subsequent sawing and milling, reduces the probability that the processed steel plate will not meet the usage requirements due to additional stress caused by deformation, and reduces material waste and production costs.
[0017] The telescopic mechanism is designed so that the support rod and support plate can be retracted together when not in use, which effectively reduces the footprint of the device, improves the utilization rate of workshop space, reduces the operating costs of enterprises, and makes the device suitable for processing sites with limited space.
[0018] The positioning component adopts a structure of bidirectional threaded rod and threaded slider, which can be adjusted according to the actual width of the steel plate to effectively fix steel plates of different widths, solving the problem that existing sawing and milling machines cannot flexibly adjust to steel plates of different widths and lengths; the setting of positioning plate and baffle can accurately position and push the steel plate, ensuring that the steel plate can move accurately to the processing area, improving processing efficiency and quality.

[0025] Please see Figures 1 to 3 A CNC steel plate sawing and milling machine sawing device includes: a sawing and milling machine body 1, support rods 5, a telescopic mechanism, a baffle 7, a positioning plate 8, and a positioning assembly. A saw blade 2 is installed inside the sawing and milling machine body 1. A top rod 3 is installed inside the sawing and milling machine body 1 near the saw blade 2. A worktable 4 is installed inside the sawing and milling machine body 1. Support rods 5 are symmetrically arranged at equal intervals on one side of the worktable 4. A support plate 6 is installed on the top of each set of support rods 5. A telescopic mechanism is installed between the worktable 4 and the support rods 5, and the telescopic mechanism drives several of the support rods 5 to extend to one side of the worktable 4. For supporting long steel plates, a baffle 7 is installed on the side wall of the plurality of support plates 6 furthest from the workbench 4. Positioning plates 8 are symmetrically installed on the top of one end of the workbench 4 near the plurality of support plates 6. A positioning assembly is installed between the workbench 4 and the positioning plates 8. The positioning assembly drives the two positioning plates 8 to move closer to each other to fix steel plates of different widths. The telescopic mechanism includes a hydraulic push rod 9 and a crossbar 10. A hydraulic push rod 9 is fixedly connected to one end of the workbench 4. A cross assembly is provided between every two adjacent support rods 5. A crossbar 10 is rotatably connected between every two symmetrical cross assemblies. The output end of the hydraulic push rod 9 is fixedly connected to one of the several crossbars 10 near the worktable 4. The cross assembly includes: connecting rod one 11 and connecting rod two 12. Both ends of the several support rods 5 are slidably connected to collars 13. The collars 13 of each pair of adjacent support rods 5 near the top of the worktable 4 are rotatably connected to connecting rod one 11. The bottom end of connecting rod one 11 is rotatably connected to the collar 13 of each pair of adjacent support rods 5 away from the worktable 4. The middle of connecting rod one 11 is rotatably connected to connecting rod two 12. The top end of connecting rod two 12 is connected to each pair of adjacent support rods. 5. A collar 13 at one end away from the worktable 4 is rotatably connected. The bottom end of the connecting rod 2 12 is rotatably connected to the collar 13 at one bottom end of each pair of adjacent support rods 5 that is closer to the worktable 4. A slide cylinder 18 is symmetrically fixedly connected to one end of the worktable 4. A slide rod 19 is slidably connected to the inner wall of each slide cylinder 18. One end of the slide rod 19 is fixedly connected to the middle of a group of support rods 5 that is closer to the baffle 7. Both ends of a group of support rods 5 that is closer to the worktable 4 are fixedly connected to the worktable 4. Rollers 20 are installed at the bottom of several groups of support rods 5 that are away from the worktable 4.
[0026] It should be noted that the sawing and milling machine body 1 is equipped with a servo motor. According to the processing requirements, the appropriate cutting parameters and blade angle are selected, the servo motor is started, and the saw blade 2 starts to rotate. At the same time, the feed speed and feed amount are adjusted to ensure that the saw blade 2 can smoothly cut into the steel plate. Under the control of the CNC system, the servo motor drives the saw blade 2 to perform sawing action. The saw blade 2 rotates and feeds along the predetermined trajectory, gradually cutting into the steel plate and completing the sawing process.
[0027] Please see Figure 1 and Figure 2 The positioning assembly includes a bidirectional threaded rod 14 and a threaded slider 15. A groove is provided on the top of the worktable 4. The inner wall of the groove is rotatably connected to the bidirectional threaded rod 14. Both ends of the bidirectional threaded rod 14 are threadedly connected to the threaded slider 15. The top ends of the threaded slider 15 are respectively fixedly connected to the corresponding positioning plates 8. The interiors of the two positioning plates 8 are rotatably connected to rollers 16 at equal intervals. One end of the bidirectional threaded rod 14 extends out of the outer wall of the worktable 4 and is fixedly connected to a crank handle 17.
[0028] It should be noted that: the operator holds and rotates the crank handle 17, which is fixed to one end of the bidirectional threaded rod 14 that extends out of the outer wall of the worktable 4. The rotation of the crank handle 17 causes the bidirectional threaded rod 14 to rotate on the inner wall of the groove at the top of the worktable 4. Since both ends of the bidirectional threaded rod 14 are threadedly connected to threaded sliders 15, and the threads of the bidirectional threaded rod 14 are opposite, when the bidirectional threaded rod 14 rotates, it will drive the two threaded sliders 15 to move towards the center. The top ends of the threaded sliders 15 are fixedly connected to the corresponding positioning plates 8, so the positioning plates 8 will also move accordingly. In this way, it can be adjusted according to the actual width of the steel plate, so that the equidistant rotating rollers 16 inside the positioning plate 8 contact the side of the steel plate. The setting of the rollers 16 can reduce the friction between the rollers and the steel plate, facilitate the movement of the steel plate, and also provide guidance during the positioning process.
[0029] The working principle of the CNC steel plate milling machine sawing device provided by this utility model is as follows:
[0030] Preliminary preparations and length adjustment of support plate 6
[0031] Before processing the long steel plate, the support length of the support plate 6 needs to be adjusted according to the actual length of the long steel plate to be processed. The operator starts the hydraulic push rod 9, and the output end of the hydraulic push rod 9 begins to push the crossbar 10 fixedly connected to it to move.
[0032] Since there is a cross assembly between every two adjacent support rods 5, and a crossbar 10 is rotatably connected between every two symmetrical cross assemblies, the cross assembly consists of a first connecting rod 11 and a second connecting rod 12. Both ends of the support rod 5 are slidably connected to collars 13. The collar 13 at the top of the support rod 5 near the worktable 4 is rotatably connected to the first connecting rod 11, and the bottom end of the first connecting rod 11 is rotatably connected to the collar 13 at the bottom end of the other support rod 5 away from the worktable 4. The middle part of the first connecting rod 11 is rotatably connected to the second connecting rod 12, the top end of the second connecting rod 12 is rotatably connected to the collar 13 at the top end of the support rod 5 away from the worktable 4, and the bottom end of the second connecting rod 12 is rotatably connected to the collar 13 at the bottom end of the support rod 5 near the worktable 4.
[0033] Among the several support rods 5, the two ends of a group near the worktable 4 are fixedly connected to the worktable 4. When the hydraulic push rod 9 pushes the crossbar 10 to move, the crossbar 10 drives the cross assembly to move. Under the action of the cross assembly, the adjacent support rods 5 extend outward along the direction defined by the slide cylinder 18 and the slide rod 19. The slide cylinder 18 is fixed to one end of the worktable 4. The slide rod 19 is fixedly connected to the middle of a group of support rods 5 near the baffle 7. The slide rod 19 slides on the inner wall of the slide cylinder 18, providing guidance and limiting for the extension of the support rods 5. At the same time, the rollers 20 installed at the bottom of the several groups of support rods 5 away from the worktable 4 reduce the friction with the ground when the support rods 5 move. As the support rods 5 extend, the support plate 6 installed at the top of them also moves in the direction pushed by the hydraulic push rod 9, thereby extending the length of the support surface to accommodate steel plates of different lengths.
[0034] Steel plate placement and width positioning
[0035] After the length of the support plate 6 is adjusted, the steel plate to be processed is placed on the workbench 4. At this time, the part of the steel plate that exceeds the workbench 4 will be supported by several support plates 6 to prevent it from bending and deforming downward due to its own weight.
[0036] Next, the steel plate needs to be positioned according to its width. The operator holds the crank handle 17 and rotates it. The crank handle 17 is fixed to one end of the bidirectional threaded rod 14 that extends out of the outer wall of the worktable 4. The rotation of the crank handle 17 drives the bidirectional threaded rod 14 to rotate on the inner wall of the groove at the top of the worktable 4. Since both ends of the bidirectional threaded rod 14 are threadedly connected to threaded sliders 15, and the threads of the bidirectional threaded rod 14 are opposite, when the bidirectional threaded rod 14 rotates, it will drive the two threaded sliders 15 to move towards the center. The top ends of the threaded sliders 15 are fixedly connected to the corresponding positioning plates 8, so the positioning plates 8 will also move accordingly. In this way, it can be adjusted according to the actual width of the steel plate, so that the equidistant rotating rollers 16 inside the positioning plate 8 contact the side of the steel plate. The setting of the rollers 16 can reduce the friction between the rollers and the steel plate, facilitate the movement of the steel plate, and also provide guidance during the positioning process.
[0037] The steel plate is moved to the processing area and fixed.
[0038] After the width positioning of the steel plate is completed, the hydraulic push rod 9 is activated again to move it in the opposite direction. The reverse movement of the hydraulic push rod 9 drives the cross bar 10 to move in the opposite direction, thereby causing the cross assembly to move. The support rod 5 and the support plate 6 retract. During the retraction process, the baffle 7 installed on the side wall of the outermost support plate 6 will contact one end of the steel plate and push the steel plate to move towards the processing area.
[0039] Once the steel plate is moved to the appropriate processing position, the hydraulic push rod 9 stops working and starts the saw milling machine body 1. The push rod 3 inside the saw milling machine body 1, near the saw blade 2, extends to fix the steel plate and prevent it from shaking due to vibration or other reasons during processing, which would affect the processing accuracy.
[0040] Steel plate sawing
[0041] After the steel plate is fixed, the saw blade 2 inside the saw milling machine body 1 starts to rotate and saw the steel plate. During the high-speed rotation, the saw blade 2 contacts the steel plate and generates cutting force, thereby realizing the sawing operation of the steel plate. During the entire processing, the support plate 6 continuously provides stable support for the steel plate, and the positioning plate 8 and the top rod 3 ensure that the position of the steel plate is fixed to ensure the quality of processing.
[0042] After processing is completed, the saw blade 2 is stopped from rotating and the push rod 3 is retracted. At this time, the hydraulic push rod 9 is in its initial state, and the support rod 5 and support plate 6 are also retracted together, reducing the footprint of the device and improving the utilization rate of workshop space.
[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
