In addition, the present invention can adapt to the cutting of strips of different widths and thicknesses and has a wide range of applications. However, it is difficult to limit and fix the material when the device is conveying and cutting it. Therefore, a CNC plate edge-wrapping, shearing and punching combined processing machine is proposed to solve the above-mentioned problems. Summary of the Invention

This allows the device to not only limit the longitudinal direction with the upper hydraulic shearing blade, but also limit the lateral direction during shearing, thereby making the shearing more stable and improving the shearing accuracy. Moreover, it eliminates the need for manual limiting, reducing the danger of manual operation. At the same time, it can directly transport the sheared material to the punching platform, realizing integrated shearing and punching, eliminating the need for manual material handling and transportation, and reducing labor input.

Moreover, during transportation, the straightening mechanism automatically straightens the square block material, so that the material falls accurately into the punching mechanism for punching, reducing manual operation and realizing integrated shearing operation.

[0007] Preferably, the punching and pressing mechanism includes a telescopic column four, a pressure plate, a telescopic spring column, a material stop, a ramp waste outlet, a waste collection box, a fixed column three, a torsion spring column, a pusher plate one, a pusher plate two, a semi-circular stop, a rotating column, a ramp discharge port, and a material collection box.

At the same time, it reduces safety hazards. After punching is completed, the punching waste automatically falls into the inclined waste outlet below and reaches the waste collection box due to gravity. Moreover, when the device is lifted after punching, it can push the previous punched workpiece away through the pusher plate to the inclined discharge port and fall into the material collection box due to gravity, completing the integrated automated operation.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

Moreover, as the device lifts up after punching, it can push the previously punched workpiece away through the pusher plate to the inclined discharge port, where it falls into the material collection box due to gravity, completing the integrated automated operation.

[0022] 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.

[0023] Please see Figures 1-9One embodiment of the present invention is: a CNC sheet metal edge-trimming, shearing, and punching combined processing machine, including a housing 3, a shearing platform 1 and a punching platform 2 fixedly connected to the upper surface of the housing 3, a housing frame 4 fixedly connected to the upper surface of the housing 3, a hydraulic shearing machine 8 and a hydraulic punching machine 9 fixedly connected to the inner wall of the housing frame 4, a feeding table 11 fixedly connected to the upper surface of the shearing platform 1, a conveyor table 10 fixedly connected to the front of the feeding table 11, a shearing clamping mechanism 5 provided on the back of the feeding table 11, a punching and pressing mechanism 7 provided at the bottom of the hydraulic punching machine 9, and a straightening mechanism 6 provided on the left side of the hydraulic punching machine 9; the shearing clamping mechanism 5 includes a fixing column 51 and a clamping base. 52. Triangular wedge block; 53. Elastic telescopic column; 54. Clamping plate; 55. Elastic telescopic rod; 56. Telescopic column two; 57. Motor; 58. Conveyor belt; 59. Material conveying inclined plate; 510. Fixed column one 51 is fixedly connected to the bottom of the hydraulic shearing machine 8; clamping base 52 is fixedly connected to the back of the feeding table 11; the bottom of the triangular wedge block 53 slides on the inner wall of the clamping base 52; one end of the elastic telescopic column 54 is fixedly connected to the right side of the triangular wedge block 53; clamping plate 55 is fixedly connected to the other end of the elastic telescopic column 54; elastic telescopic rod 56 is fixedly connected to the upper surface of the clamping base 52; telescopic column two 57 is fixedly connected to the left side of the elastic telescopic rod 56; the device starts to operate. During operation, the material plate is first transported via conveyor 10 and enters from feeding table 11. When the material reaches a certain size, the hydraulic shear 8 begins to move downwards and press down. At this time, the hydraulic shear 8 drives the fixed column 51 to move downwards. When it touches the triangular wedge block 53, since the triangular wedge block 53 is connected to the clamping plate 55 through the elastic telescopic column 54, it pushes the clamping plate 55 to move. When the clamping plate 55 touches the workpiece, due to the force, the elastic telescopic column 54 begins to retract, clamping the material and preventing it from moving. When the hydraulic shear 8 moves upwards, the triangular wedge block 53 is subjected to the action of the telescopic column 57. The resetting mechanism releases the workpiece. The motor 58 is fixedly connected to the upper surface of the shearing platform 1, and the conveyor belt 59 is installed at the output end of the motor 58. The right side of the conveyor belt 59 contacts the right side of the material conveying sloping plate 510 and the right side of the material conveying sloping plate 510 contacts the punching platform 2. The triangular inclined block 53 is slidably connected to the inner wall of the clamping base 52. The front of the hydraulic shearing machine 8 contacts the back of the feeding table 11. At this time, the workpiece falls onto the conveyor belt 59 due to gravity. The conveyor belt 59 rotates clockwise due to the drive of the motor 58, transporting the material to the material conveying sloping plate 510. The feeding is achieved through gravity, which improves work efficiency and realizes automatic material discharge.

[0024] Working Principle: When the device starts operating, the material plate is first transported via the conveyor 10 and enters from the feeding platform 11. When the material reaches a certain size, the hydraulic shear 8 begins to move downwards and press down. At this time, the hydraulic shear 8 drives the fixed column 51 to move downwards and touches the triangular wedge 53. Since the triangular wedge 53 is connected to the clamping plate 55 through the elastic telescopic column 54, it pushes the clamping plate 55 to move. When the clamping plate 55 touches the workpiece, due to the force, the elastic telescopic column 54 begins to contract, clamping the material and preventing it from moving. When the hydraulic shear 8 moves upwards, the triangular wedge 53 is reset by the telescopic column 57, thereby releasing the workpiece. At this time, the workpiece falls onto the conveyor belt 59 due to gravity. The conveyor belt 59 rotates clockwise due to the drive of the motor 58, transporting the material to the conveying inclined plate 510. The feeding is achieved through gravity, improving work efficiency and realizing automatic material discharge.

[0025] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the straightening mechanism 6 includes a slide rail 61, a brush plate 62, a fixing block 63, a telescopic column 64, a push column 65, a debris collection box 66, a fixing column 67, an arc-shaped stop block 68, a connecting column 69, a transmission plate 611, a gear 612, a rack 613, a straightening plate 614, a base plate 615, and a spring 616. The slide rail 61 is fixedly connected to the upper surface of the shearing platform 1, the fixing block 63 is fixedly connected to the upper surface of the shearing platform 1, and the telescopic column 64 is fixedly connected to the upper surface of the shearing platform 1. On the left side of the fixed block 63, an elastic element is installed inside the telescopic column 64. The brush plate 62 is slidably connected to the inner wall of the slide rail 61. The debris collection box 66 is set on the inner wall of the shearing platform 1. The push column 65 is fixedly connected to the outer surface of the conveyor belt 59. During the shearing process, this device will generate a lot of waste slag. If it is not treated in time, it will affect the processing accuracy. When the conveyor belt 59 rotates, it will drive the push column 65 to move. The push column 65 will push the brush plate 62 to move. The brush plate 62 moves on the slide rail 61, thereby brushing away the waste and collecting the debris on the left side. The collection box 66 and the fixed column 67 are fixedly connected to the lower surface of the hydraulic shear 8. The base plate 615 is fixedly connected to the upper surface of the conveying inclined plate 510. One end of the spring 616 is fixedly connected to the left side of the base plate 615, and the right side of the transmission plate 611 is fixedly connected to the other end of the spring 616. One end of the connecting column 69 is fixedly connected to the right side of the transmission plate 611. The left side of the arc-shaped stop block 68 is fixedly connected to the other end of the connecting column 69. The rack 613 is set inside the transmission plate 611, and the gear 612 is rotatably connected to the upper surface of the conveying inclined plate 510. Plate 614 is fixedly connected to the circumferential surface of gear 612. The material slides on the conveying inclined plate 510. When the hydraulic shearing machine 8 moves downward, it will drive the fixed column 67 to move downward. The downward movement of the fixed column 67 will push the arc-shaped stop 68. Because it is connected to the connecting column 69, the transmission plate 611 moves downward. Because there is a rack 613 on the inner wall of the transmission plate 611, the rack 613 drives the gear 612 to rotate. The rotation of the gear 612 drives the straightening plate 614 to close inward, thereby straightening the material and making it fall stably below the hydraulic punching machine 9.

[0026] The punching and clamping mechanism 7 includes a telescopic column four 71, a pressure plate 72, a telescopic spring column 73, a material stop 74, a ramp waste outlet 75, a waste collection box 76, a fixed column three 77, a torsion spring column 78, a pusher plate one 79, a pusher plate two 711, a semi-circular stop 712, a rotating column 713, a ramp discharge port 714, and a material collection box 715. One end of the telescopic column four 71 is fixedly connected to the bottom of the hydraulic punching machine 9, and the upper surface of the pressure plate 72 is fixedly connected to the other end of the telescopic column four 71. One end of column 73 is fixedly connected to the bottom of hydraulic punching machine 9, and the upper surface of pressure plate 72 is fixedly connected to the other end of telescopic spring column 73. Sloping waste outlet 75 is located on the inner wall of the side of punching platform 2. Waste collection box 76 is fixedly connected to the outlet of sloping waste outlet 75, and material stop 74 limits its movement. Hydraulic punching machine 9 moves downwards to punch the material. The punched waste falls into sloping waste outlet 75 and, due to gravity, into waste collection box 76, simultaneously driving pressure plate 73. 2. Moving downwards, the material is first compressed, and the telescopic spring column 73 retracts to achieve stable punching. The bottom end of the fixed column three 77 is fixedly connected to the upper surface of the punching platform 2. The torsion spring column 78 is installed on the side of the fixed column three 77. The pusher plate one 79 is rotatably installed on the circumferential surface of the torsion spring column 78. The semi-circular stop block 712 is fixedly connected to the upper surface of the pusher plate one 79. The inclined discharge port 714 is opened on the upper surface of the punching platform 2. The material collection box 715 is fixedly connected to the inner wall of the inclined discharge port 714. The pusher plate one 79... 9 is connected to the pusher plate 711 via the rotating column 713. The pusher plate 711 is located on the movement trajectory of the pressure plate 72. At this time, the pusher plate 79 is reset to the vertical state. When the pressure plate 72 is lifted, the pressure plate 72 drives the semi-circular stop block 712 to rotate, so that the pusher plate 711 pushes the workpiece away and pushes it onto the inclined discharge port 714. Due to gravity, it falls into the material collection box 715, completing the punching. This realizes the integration of punching and discharge, reduces manual operation, and can collect waste materials at the same time.

[0027] Working principle: This device generates a lot of waste slag during the shearing process. If not handled in time, it will affect the processing accuracy. When the conveyor belt 59 rotates, it will drive the push column 65 to move. The push column 65 will push the brush plate 62 to move. The brush plate 62 moves on the slide rail 61, thereby brushing away the waste and letting it fall into the debris collection box 66 on the left. At this time, the material slides on the conveying inclined plate 510. When the hydraulic shearing machine 8 moves downward, it will drive the fixed column 67 to move downward. The downward movement of the fixed column 67 will push the arc-shaped stop 68. Because it is connected to the connecting column 69, the transmission plate 611 moves downward. Because the inner wall of the transmission plate 611 has a rack 613, the rack 613 drives the gear 612 to rotate. The rotation of the gear 612 drives the straightening plate 614 to close inward, thereby straightening the material and making it fall stably below the hydraulic punching machine 9.

[0028] The material stop 74 limits the material, and the hydraulic punch 9 moves down to punch the material. The waste material after punching falls into the inclined waste outlet 75. Due to gravity, it falls into the waste collection box 76, which simultaneously drives the pressure plate 72 to move down and first press the material. The telescopic spring column 73 retracts to achieve stable punching. At this time, the pusher plate 79 returns to the vertical position. When the pressure plate 72 is lifted, it drives the semi-circular stop 712 to rotate, causing the pusher plate 711 to push the workpiece away and onto the inclined outlet 714. Due to gravity, it falls into the material collection box 715, completing the punching. This achieves integrated punching and discharging, reduces manual operation, and collects waste material.

[0029] This invention provides a CNC sheet metal edge-wrapping, shearing, and punching combined processing machine. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
