Description

Technical Field

[0002] A shearing machine is a type of machine tool. It is hydraulically driven, with reliable safety performance and convenient operation. By using a cutting motion in the vertical direction, it extrudes, bends, or cuts a sheet. In modern mechanical structures, sheets with different inclined angles are often required, which leads to an increasing demand for sheet processing. However, the existing shearing machines can only move in a single vertical direction, that is, move perpendicular to the sheet, so the cut surface of the sheet is mostly a vertical surface, which does not meet the requirements of the inclined surfaces of the sheets in some mechanical mechanisms.

Detailed implementation manner

[0008] The present invention will be further described in detail below with reference to the accompanying drawings.

[0009] As Figures 1 to 10 shown, the structure and function of a shearing machine tool based on a rotating disc cutter will be described in detail below; A shearing machine tool based on a rotating disc cutter includes a bottom plate Ⅰ 11 and a bottom plate Ⅱ 41. A cutting space is formed between the bottom plate Ⅰ 11 and the bottom plate Ⅱ 41. A moving track 61 is fixedly connected between the sides of the bottom plate Ⅰ 11 and the bottom plate Ⅱ 41. A moving seat 63 is slidably connected to the moving track 61. A swing motor 64 is fixedly connected to the moving seat 63. A swing rod 65 is fixedly connected to the output shaft of the swing motor 64. A telescopic mechanism Ⅴ 66 is fixedly connected to the swing rod 65. A disc cutter 67 is rotatably connected to the telescopic end of the telescopic mechanism Ⅴ 66; During use, the plate to be cut is placed on the bottom plate Ⅰ 11 and the bottom plate Ⅱ 41. The cutting position of the plate is located between the bottom plate Ⅰ 11 and the bottom plate Ⅱ 41. The moving seat 63 is pushed to slide on the moving track 61. The moving seat 63 drives the swing motor 64 to move. The swing motor 64 drives the swing rod 65 to move. The swing rod 65 drives the telescopic mechanism Ⅴ 66 to move. The telescopic mechanism Ⅴ 66 drives the disc cutter 67 to move, thereby adjusting the position of the disc cutter 67. When it is necessary to adjust the inclination angle of its cutting forming surface, the swing motor 64 is started. The swing motor 64 is preferably a servo motor. The output shaft of the swing motor 64 starts to rotate. The output shaft of the swing motor 64 drives the swing rod 65 to swing, thereby adjusting the inclination angle of the swing rod 65. The swing rod 65 drives the telescopic mechanism Ⅴ 66 to move, thereby adjusting the inclination angle of the telescopic mechanism Ⅴ 66. The telescopic mechanism Ⅴ 66 drives the disc cutter 67 to move, thereby adjusting the inclination angle of the disc cutter 67; A power mechanism for driving the rotary cutting disc 67 is fixedly connected to the output shaft of the telescopic mechanism V66. The power mechanism is preferably a servo motor. The rotary cutting disc 67 is driven to rotate by the power mechanism. When the telescopic mechanism V66 is started, the telescopic mechanism V66 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism V66 drives the rotary cutting disc 67 to move, so that the rotary cutting disc 67 moves downward at a certain inclination angle and rotates. Then, the rotary cutting disc 67 cuts the plate, and an inclined surface is formed at the cut of the plate. Further, in order to facilitate driving the moving seat 63 to move on the moving track 61, a lead screw 62 is rotatably connected to the moving track 61. The moving seat 63 is threadedly connected to the lead screw 62. A power mechanism for driving the lead screw 62 to rotate is fixedly connected to the moving track 61. The power mechanism is preferably a servo motor. The output shaft of the power mechanism drives the lead screw 62 to rotate. When the lead screw 62 rotates, it drives the moving seat 63 to move through the thread. Then, by controlling the movement of the moving seat 63, the moving position of the rotary cutting disc 67 is controlled, and thus the moving position of the rotary cutting disc 67 and the cutting position of the plate are adjusted. In the actual use process, since the plate to be cut needs to be placed on the bottom plate I 11 and pushed forward to move from the bottom plate I 11 to the bottom plate II 41, the plate will move on the upper side surface of the bottom plate I 11. In order to reduce the frictional force between the bottom plate I 11 and the plate; Side plates I 12 are fixedly connected to the bottom of the bottom plate I 11. A plurality of support rollers I 13 are rotatably connected to the side plates I 12. A support belt I 14 is covered between the plurality of support rollers I 13. A notch is provided in the middle of the bottom plate I 11, and the support belt I 14 is arranged in the notch. Then, as Figure 3 shown, the plate is placed on the support belt I 14, and the plurality of support rollers I 13 provide internal support for the support belt I 14. Then, when the plate moves, it drives the support belt I 14 to move, and the plurality of support rollers I 13 will rotate. Thus, the frictional force received when the plate moves is reduced, the friction on the side surface of the plate is reduced, and the side surface of the plate is prevented from being damaged. Further, in order to automatically control the amount of movement of the plate on the bottom plate I 11, that is, the length of the bottom plate I 11 extending out, so as to cut plates of different lengths, two telescopic mechanisms I 21 are fixedly connected to the bottom plate I 11, and slide rails 22 are fixedly connected to the telescopic ends of the two telescopic mechanisms I 21. Two telescopic mechanisms II 32 are rotatably connected to the two slide rails 22. An articulated column 33 is fixedly connected between the telescopic ends of the two telescopic mechanisms II 32. A sliding seat 38 is slidably connected between the two slide rails 22. A connecting rod 37 is hinged between the sliding seat 38 and the articulated column 33. A telescopic mechanism III 39 is fixedly connected to the sliding seat 38, and a pushing plate 310 is fixedly connected to the telescopic end of the telescopic mechanism III 39; After placing the sheet on the supporting belt I 14, start the telescopic mechanism III 39. The telescopic mechanism III 39 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 39 drives the pushing plate 310 to move, so that the pushing plate 310 moves downward to contact the sheet. And in order to increase the frictional force between the sheet and the pushing plate 310, a plurality of inclined teeth are provided at the lower end of the pushing plate 310, such as Figure 2 shown. When the inclined teeth contact the sheet, since the vertical surface of the inclined teeth is on the same side as the movement direction of the sheet, the driving force on the sheet can be increased; A driving motor 31 for driving the telescopic mechanism II 32 to rotate is fixedly connected to one side of the slide rail 22. Start the driving motor 31. The driving motor 31 is preferably a servo motor. The output shaft of the driving motor 31 starts to rotate. The output shaft of the driving motor 31 drives the telescopic mechanism II 32 to rotate. The telescopic mechanism II 32 drives the hinged column 33 to rotate. The hinged column 33 drives the connecting rod 37 to move. The connecting rod 37 drives the sliding seat 38 to slide between the two slide rails 22. The sliding seat 38 drives the telescopic mechanism III 39 to move. The telescopic mechanism III 39 drives the pushing plate 310 to move. The pushing plate 310 drives the sheet to move, so that the sheet moves forward, and the front end of the sheet passes through the circular cutter 67 and moves onto the bottom plate II 41. The circular cutter 67 cuts the protruding position of the sheet; After cutting is completed, the telescopic end of the telescopic mechanism III 39 drives the pushing plate 310 to move upward, so that the pushing plate 310 is separated from the sheet. Then the pushing plate 310 moves to the extreme position at the rear under the drive of the connecting rod 37. Then start the telescopic mechanism III 39 again, so that the pushing plate 310 contacts the sheet. The pushing plate 310 pushes the sheet forward again, and the circular cutter 67 cuts the protruding position of the sheet. In this way, the sheet is cut multiple times in a cycle; Here, it needs to be explained in detail that, as Figure 7 shown, when the hinged column 33 moves from front to back, the pushing plate 310 is separated from the sheet. When the hinged column 33 moves from back to front, the pushing plate 310 contacts the sheet, which is the pushing cycle; When it is necessary to adjust the cutting length of the sheet, that is, the distance that the pushing plate 310 can push the sheet forward each time it moves, start the telescopic mechanism II 32. The telescopic mechanism II 32 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 32 drives the hinged column 33 to move, thereby adjusting the position of the hinged column 33, adjusting the pushing radius of the telescopic mechanism II 32 when rotating on the hinged column 33, and thus adjusting the length that the telescopic mechanism II 32 pushes the sheet forward each time it rotates; Further, to facilitate the control of the motion state of the pusher plate 310, that is, when the articulated column 33 moves from front to back, the pusher plate 310 separates from the sheet material, and when the articulated column 33 moves from back to front, the pusher plate 310 contacts the sheet material; Further, to cut sheets of different thicknesses, the telescopic mechanism I 21 is activated. The telescopic mechanism I 21 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 21 drives the slide rail 22 to move, thereby adjusting the height of the pusher plate 310, and further controlling the thickness of the sheet material that the pusher plate 310 can push; A sector cam I 34 is rotatably connected to the slide rail 22 on the other side. The sector cam I 34 is fixedly connected to the corresponding telescopic mechanism II 32. A sector cam II 35 is rotatably connected to the sector cam I 34. A locking nail 36 is threadedly connected to the sector cam II 35. Sensors 311 are arranged on the upper sides of the sector cam I 34 and the sector cam II 35. The sensors 311 are fixedly connected to the slide rail 22. Both the sector cam I 34 and the sector cam II 35 can contact the sensors 311. The sensors 311 are connected to the telescopic mechanism III 39; The sensors 311 and the telescopic mechanism III 39 are connected by conventional electronic control means in the art. The sensors 311 can be contact sensors or extrusion sensors. When the sensors 311 are extruded, the telescopic end of the telescopic mechanism III 39 extends, thereby making the pusher plate 310 contact the sheet material. When the sensors 311 are not extruded, the telescopic end of the telescopic mechanism III 39 resets and retracts, thereby making the pusher plate 310 separate from the sheet material; As Figure 7 shown, when the driving motor 31 is operating, the output shaft of the driving motor 31 drives the telescopic mechanism II 32 to move. The telescopic mechanism II 32 drives the sector cam I 34 to rotate. When the articulated column 33 moves from front to back, the sector cam I 34 does not extrude the sensors 311, and the pusher plate 310 separates from the sheet material. When the articulated column 33 moves from back to front, the sector cam I 34 extrudes the sensors 311, and the pusher plate 310 contacts the sheet material; Further, since the sensors 311 themselves have a certain extrusion width, it may cause the pusher plate 310 to contact the sheet material in advance or the pusher plate 310 to contact the sheet material with a delay. Therefore, a rotatable sector cam II 35 is provided. The rotational position of the sector cam II 35 on the sector cam I 34 is adjusted, and the sector cam II 35 is fixed by the locking nail 36, thereby fixing the opening arc between the sector cam II 35 and the sector cam I 34. The sector cam II 35 can also extrude the sensors 311, and thus, according to the processing requirements, the motion modes such as whether the pusher plate 310 contacts the sheet material in advance or contacts the sheet material with a delay can be adjusted; Further, after the sheet moves onto the bottom plate II 41, in order to clamp the sheet during the cutting process, a telescopic mechanism IV 51 is fixedly connected to the bottom plate II 41. A side plate II 52 is fixedly connected to the telescopic end of the telescopic mechanism IV 51. A plurality of support rollers II 53 are rotatably connected to the side plate II 52, and a support belt II 54 is wrapped between the plurality of support rollers II 53; The upper side of the sheet is clamped by the support belt II 54. The telescopic mechanism IV 51 is started. The telescopic mechanism IV 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV 51 drives the side plate II 52 to move. The side plate II 52 drives the support rollers II 53 to move. The support rollers II 53 drive the support belt II 54 to move, thereby adjusting the height of the support belt II 54 and the height at which the support belt II 54 contacts the sheet, so that the support belt II 54 can clamp sheets of different heights; A shearing process based on a rotary disc cutter, the process comprising the following steps: Step 1: Place the sheet to be cut on the bottom plate I 11 and the bottom plate II 41; place the sheet to be cut on the bottom plate I 11, and push the sheet to move on the bottom plate I 11 so that the bottom plate I 11 passes through the cutting space between the bottom plate I 11 and the bottom plate II 41 and moves onto the bottom plate II 41; Step 2: The cutting position of the sheet is between the bottom plate I 11 and the bottom plate II 41, and the inclination angle of the disc cutter 67 is adjusted; the swing motor 64 is started. The swing motor 64 is preferably a servo motor. The output shaft of the swing motor 64 starts to rotate. The output shaft of the swing motor 64 drives the swing rod 65 to swing, thereby adjusting the inclination angle of the swing rod 65. The swing rod 65 drives the telescopic mechanism V 66 to move, thereby adjusting the inclination angle of the telescopic mechanism V 66. The telescopic mechanism V 66 drives the disc cutter 67 to move, thereby adjusting the inclination angle of the disc cutter 67 Step 3: The disc cutter 67 cuts the sheet between the bottom plate I 11 and the bottom plate II 41, so that the cut of the sheet forms an inclined surface; a power mechanism for driving the disc cutter 67 to rotate is fixedly connected to the output shaft of the telescopic mechanism V 66. The power mechanism is preferably a servo motor. The disc cutter 67 is driven to rotate by the power mechanism. The telescopic mechanism V 66 is started. The telescopic mechanism V 66 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism V 66 drives the disc cutter 67 to move, so that the disc cutter 67 moves downward at a certain inclination angle and the disc cutter 67 rotates, and thus the disc cutter 67 cuts the sheet, so that the cut of the sheet forms an inclined surface.
