Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing equipment, and in particular to a sheet metal cutting device. Background Technology

[0002] Panel cutting is the first step in panel furniture manufacturing and a key process that determines cost and efficiency. Simply put, it involves cutting a large sheet of wood into several "components" of different shapes and sizes according to the dimensions required by the design drawings.

[0003] In related technologies, such as Chinese patent publication number CN213499773U, a panel clamping device for a furniture panel cutting machine is proposed. This device includes a cutting machine, a guide rail mounted on the top of the cutting machine, a slider connected to the surface of the guide rail, a cutter head mounted on the bottom of the slider, a fixing plate fixedly connected to the bottom of the slider, and two springs A fixedly connected to the bottom of the fixing plate. A fixing block is fixedly connected to the bottom of each spring A. The fixing block first contacts the panel surface. After the fixing block contacts the panel, the cutter head and fixing plate continue to press down, compressing the springs A. The elasticity of the springs A allows the fixing block to press and fix the panel in position until the cutter head contacts the panel for processing. After processing, the cutter head lifts, causing the fixing plate and fixing block to lift, thus releasing the panel. Compared to traditional clamping devices, this device completes the clamping before processing and immediately releases the clamp after processing, making it more flexible and improving ease of use.

[0004] The panel saw is mainly used to cut large-area boards into smaller-area boards. The panel saw mentioned above is mainly suitable for processing such as drilling holes in the board. When the panel saw is used to cut the board, the movement of the cutter head and the movement of the fixing block can easily cause the fixing block to scratch the surface of the board, affecting the quality of the board. Summary of the Invention

[0005] To address the issue of easily scratched boards affecting their quality, this application provides a board cutting device.

[0006] The plate cutting equipment provided in this application adopts the following technical solution:

[0007] A sheet metal cutting device, comprising:

[0008] Workbench;

[0009] A support frame is fixedly mounted on a workbench, and a cutting blade is rotatably connected to the support frame. The rotation axis of the cutting blade is perpendicular to the feeding direction of the sheet material.

[0010] A clamping plate is connected to the bracket and can move in a direction close to or away from the workbench. A clamping wheel is rotatably connected to the side of the clamping plate close to the workbench, and the clamping wheel can abut against the side of the plate away from the ground.

[0011] The pusher plate is connected to the worktable and can move toward or away from the cutting blade.

[0012] Furthermore, the pusher plate includes:

[0013] Connecting sub-board, which is connected to the worktable;

[0014] A pusher plate is rotatably connected to the connecting plate. A baffle is fixedly connected to the connecting plate. The baffle is located on the side of the pusher plate away from the plate and can abut against the pusher plate.

[0015] Furthermore, the pusher plate also includes a connecting sub-plate, which is connected to the worktable and is spaced apart from the worktable surface. The connecting sub-plate can move in a direction closer to or further away from the worktable. The connecting sub-plate is spaced apart from the connecting sub-plate and can move in a direction closer to or further away from the connecting sub-plate.

[0016] Furthermore, a rotating plate is rotatably connected to the connecting sub-plate, and the rotating plate is rotatably connected to the connecting sub-plate, and the rotating plate is inclined towards the worktable along the direction close to the connecting sub-plate.

[0017] Furthermore, the sheet metal cutting equipment also includes a traction clamp, which comprises:

[0018] A fixed clamp is connected to the worktable and can move along the feeding direction of the sheet material;

[0019] Rotate the clamping plate to rotatably connect it with the fixed clamping plate;

[0020] The workbench is equipped with a rotating assembly for driving the rotating clamp plate to rotate.

[0021] Furthermore, the rotating assembly includes:

[0022] A rotating gear is fixedly connected to the rotating clamp plate, the rotating shaft is fixedly connected to the fixed clamp plate, and the rotating gear is fixedly connected to the rotating shaft coaxially.

[0023] The rotating rack slides and connects with the fixed clamping plate, and meshes with the rotating gear.

[0024] Furthermore, a clamping plate is rotatably connected to the free end of the rotating clamp.

[0025] Furthermore, the rotating box is threaded with an adjusting bolt, which can abut against the end wall of the rotating rack.

[0026] In summary, the beneficial technical effects of this application are as follows:

[0027] 1. The clamping roller is designed so that it can rotate when the pusher plate pushes the plate, thereby reducing the relative displacement between the clamping roller and the plate and making the plate surface less likely to be scratched, thus making the plate quality less affected;

[0028] 2. The rotating connection between the rotating clamp and the fixed clamp allows the traction clamp to move the plate to the appropriate position, and then the rotating clamp opens, making it easier for workers to remove the plate from the workbench.

[0029] 3. The adjustable bolts allow the traction clamp to be used for clamping plates of different thicknesses. Attached Figure Description

[0038] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] This application discloses a sheet metal cutting device. (Refer to...) Figure 1 It includes a workbench 1, a support 3, a clamping plate 4, a pusher plate 5, and a traction clamp 6.

[0040] The workbench 1 is fixedly mounted on the ground. The support 3 is fixedly mounted on the side of the workbench 1 facing away from the ground. A cutting blade 31, a circular saw blade, is rotatably connected to the support 3, and its rotation axis is perpendicular to the material feeding direction. The workbench 1 has a receiving hole 11 for accommodating the cutting blade 31. A cutting motor for driving the cutting blade 31 is mounted on the support 3. The motor body is fixedly connected to the support 3, and the output shaft of the motor is coaxially fixedly connected to the cutting blade 31, thus enabling the cutting motor to drive the cutting blade 31 to rotate and cut the material.

[0041] Two clamping plates 4 are provided, positioned on either side of the cutting blade 31, and can move towards or away from the worktable 1. Multiple clamping wheels 41 are rotatably connected to the side of the clamping plate 4 closest to the worktable 1, with the axes of the clamping wheels 41 parallel to the axis of the cutting blade 31. Clamping rods 42 are fixedly connected to the side of each clamping plate 4 away from the worktable 1, and the two clamping rods 42 extend from the bracket 3 and are fixedly connected via a connecting plate 43. To enable the movement of the clamping plates 4, a clamping cylinder 44 is provided on the side of the bracket 3 away from the worktable 1. The cylinder body of the clamping cylinder 44 is fixedly connected to the bracket 3, and the piston rod of the clamping cylinder 44 is fixedly connected to the connecting plate 43, thus allowing the clamping cylinder 44 to move the clamping plates 4 and clamping wheels 41 towards or away from the worktable 1 during operation.

[0042] Reference Figure 1 and Figure 2 The pusher plate 5 moves in a direction close to or away from the cutting blade 31. To achieve this movement, a drive assembly 54 is provided on the worktable 1. The drive assembly 54 includes a drive plate 541, a drive screw 542, and a drive motor 543. Two drive screws 542 and two drive motors 543 are provided, with one drive motor 543 corresponding to one drive screw 542. The two drive screws 542 are located on opposite sides of the pusher plate 5. The bodies of both drive motors 543 are fixedly connected to the worktable 1, and each drive motor 543's output shaft is coaxially and fixedly connected to a drive pulley 5421 on its corresponding drive screw 542. The two drive pulleys 5421 are connected via a drive belt 5432.

[0043] Reference Figure 1 , Figure 3 and Figure 4The pusher plate 5 includes a connecting sub-plate 51, a pushing sub-plate 52, and a connecting sub-plate 53. The connecting sub-plate 53 has a groove 531 along its length. A drive plate 541 passes through the groove 531, and the size of the groove 531 is larger than the size of the drive plate 541 in the direction closer to the worktable 1, allowing the connecting sub-plate 53 to move closer to or further away from the worktable 1. Both ends of the drive plate 541 extend out of the groove 531, and the drive plate 541 is threadedly connected to the corresponding drive screw 542, allowing the drive screw 542 to rotate and move the drive plate 541 closer to or further away from the cutting blade 31. A return spring is provided on the connecting sub-plate 53, located in the groove 531. One end of the return spring is fixedly connected to the side wall of the groove 531, and the other end is fixedly connected to the drive plate 541. Under the elastic force of the return spring 532, the connecting sub-plate 53 is spaced apart from the worktable 1 surface. The connecting subplate 51 has a through hole 513 for the drive screw 542 to pass through. The connecting subplate 53 is spaced apart from the connecting subplate 51. The pushing subplate 52 is rotatably connected to the connecting subplate 51. The center of gravity of the pushing subplate 52 is set close to the worktable 1 so that the pushing subplate 52 can be in a vertical state under its own weight. A baffle 512 is fixedly connected to the connecting subplate 51. The baffle 512 is located on the side of the pushing subplate 52 away from the material, and the baffle 512 can abut against the pushing subplate 52, so that the free end of the pushing subplate 52 can only rotate in the direction closer to the cutting blade 31, thus making it less likely for the pushing subplate 52 to affect the feeding of the material to be processed. A rotating plate 511 is rotatably connected to the connecting subplate 51. The rotating plate 511 is rotatably connected to the connecting subplate 53, and the rotating plate 511 is tilted in the direction closer to the worktable 1 along the direction closer to the connecting subplate 53.

[0044] In order to ensure that the push plate 52 and the connecting plate 53 make tight contact when they come into contact, the connecting plate 53 is provided with a receiving groove for accommodating the rotating plate 511.

[0045] When the pusher plate 5 pushes the plate to move, the pusher plate 52 drives the connecting plate 51 to move closer to the connecting plate 53, thereby causing the connecting plate 53 to move closer to the worktable 1, so that the connecting plate 53 can support the pusher plate 52, thereby improving the stability of the pusher plate 5 pushing the plate.

[0046] Reference Figure 1 , Figure 5 and Figure 6The traction clamp 6 and the pusher plate 5 are respectively located on both sides of the bracket 3. The traction clamp 6 includes a fixed clamping plate 61 and a rotating clamping plate 62. The fixed clamping plate 61 is connected to the worktable 1 and can move along the feeding direction of the material. The rotating clamping plate 62 is arranged in an "L" shape, and a rotating shaft 621 is fixedly connected to the rotating clamping plate 62. The rotating shaft 621 is rotatably connected to the fixed clamping plate 61. The worktable 1 is provided with a rotating assembly 7 for driving the rotating clamping plate 62 to rotate.

[0047] Two sets of rotating components 7 are provided, and the two sets of rotating components 7 are respectively located on both sides of the fixed clamping plate 61. The rotating component 7 includes a rotating box 71, a rotating gear 72, and a rotating rack 73. The rotating box 71 is fixedly connected to the fixed clamping plate 61. Both ends of the rotating shaft 621 are inserted into the rotating box 71 on the corresponding side. The rotating gear 72 is located inside the rotating box 71 and is coaxially fixedly connected to the rotating shaft 621. A rotating track 712 is fixedly connected inside the rotating box 71. The rotating rack 73 has a rotating groove adapted to the shape of the rotating track 712. The rotating rack 73 is slidably connected to the rotating track 712, thereby realizing the sliding connection between the rotating rack 73 and the rotating box 71. A sliding track 12 is fixedly connected to the worktable 1. A sliding groove 713 adapted to the shape of the sliding track 12 is opened on the rotating box 71, thereby realizing the sliding connection between the rotating box 71 and the sliding track 12.

[0048] In this embodiment, to achieve the movement of the rotating box 71, a moving assembly 8 for driving the rotating box 71 is provided on the worktable 1. Two sets of moving assemblies 8 are provided, with one set corresponding to one set of rotating assemblies 71. The moving assembly 8 includes a moving motor 81 and a moving lead screw 82. The body of the moving motor 81 is fixedly connected to the worktable 1. Moving pulleys 811 are coaxially fixedly connected to the output shafts of both the moving lead screw 82 and the moving motor 81. The two moving pulleys 811 are connected by a moving belt 812. The moving lead screw 82 is a bidirectional lead screw, and its slider is fixedly connected to a rotating rack 73. A moving hole 714 is provided on the rotating box 71 for the moving lead screw 82 to pass through.

[0049] In order to enable the traction clamp 6 to better clamp the plate, a clamping plate 622 is rotatably connected to the free end of the rotating clamping plate 62. A torsion spring is fixedly connected to the clamping plate 622, and the other end of the torsion spring is fixedly connected to the rotating clamping plate 62. When the free end of the rotating clamping plate 62 is rotated to a horizontal position, under the action of the torsion spring, the angle between the side of the rotating clamping plate 62 away from the ground and the clamping plate is greater than 90°, so that the clamping plate 622 is less likely to interfere with the rotation of the rotating clamping plate 62 to the point of contact with the surface of the plate.

[0050] In order to enable the traction clamp 6 to be adapted to clamping plates of different thicknesses, the rotating box 71 is threaded with an adjusting bolt 711, which can abut against the end wall of the rotating rack 73.

[0051] To facilitate the operation of the moving component 8, a sensor for detecting the movement of the plate onto the fixed clamping plate 61 is fixedly connected to the rotating box 71. In this embodiment, the sensor is a photoelectric sensor, which is electrically connected to the moving motor 81 to control the operation of the moving motor 81.

[0052] The implementation principle of the sheet metal cutting equipment in this application embodiment is as follows: The operator places the sheet metal on the workbench 1, and the drive motor 543 runs to drive the drive screw 542 to drive the push plate to move the sheet metal towards the cutting blade 31, so that the cutting blade 31 can cut the sheet metal. When the sheet metal to be cut moves to the fixed clamping plate 61, the sensor detects the sheet metal and transmits the electrical signal to the moving motor 81, so that the moving motor 81 runs and drives the moving screw 82 to make the rotating rack 73 slide first and drive the rotating gear 72 to rotate, that is, the rotating clamping plate 62 rotates, until the rotating clamping plate 62 is in close contact with the surface of the sheet metal. At this time, the rotating rack 73 drives the rotating box 71 to slide, thus realizing the movement of the sheet metal.
