Detailed implementation mode

[0031] It should be noted that next, in combination with the accompanying drawings provided by the present invention and the markings in the accompanying drawings, corresponding to the technical solutions of the present invention, the technical solutions of the present invention will be described in detail and completely. However, the described content will inevitably only be one of the embodiments shown by the technical solutions of the present invention, and cannot cover all the content of the present invention. Therefore, based on the embodiments cited in the present invention, any embodiments derived without substantial creation by those skilled in the art will fall within the protection scope of the present invention.

[0032] Embodiment: A laser cutting machine for processing special-shaped chain plates, refer to Figures 1 - 3 , including: processing table 1, frame 2, laser machine 3, separation table 4, italic 4a, motor X 5, brush roller 6, arc-shaped guide plate 24 and collection box 25; a frame 2 is slidably installed on the top of the processing table 1, and the frame 2 moves left and right on the processing table 1; a laser machine 3 is slidably installed on the frame 2, and the laser machine 3 moves back and forth on the processing table 1; a separation table 4 is fixedly installed on the top of the processing table 1, the separation table 4 is located below the laser machine 3, the separation table 4 is provided with layer-by-layer italic 4a, a separation groove 4b is opened at the bottom of the separation table 4, and the separation groove 4b is arranged between the italic 4a, and a freely extractable collection tray is provided on the processing table 1, and the collection tray is located below the separation table 4; a support plate is fixed on the right side of the frame 2, and a motor X 5 is fixedly installed on the support plate; a brush roller 6 is rotatably installed on the support plate of the frame 2, the brush roller 6 is fixed to the output end of the motor X 5, and the bristles on the brush roller 6 are arranged in a spiral shape, so that when the brush roller 6 rotates, its bristles can brush out the chain plates from back to front. The bristles of the brush roller 6 are made of hard steel wires, so that when the brush roller 6 rotates, it can move the chain plates forward for discharging; an arc-shaped guide plate 24 is fixedly installed on the front side of the processing table 1, and the rear side of the arc-shaped guide plate 24 is docked with the front side of the separation table 4; a collection box 25 is fixedly installed on the front side of the processing table 1, and the rear side of the collection box 25 is docked with the front side of the arc-shaped guide plate 24. After the brush roller 6 rotates and brushes out the chain plates forward, the chain plates will be guided by the arc-shaped guide plate 24 and collected in the collection box 25.

[0033] When using this device to produce chain pieces, place the steel plate on the separation table 4, input the moving position parameters of the laser machine 3, start the laser machine 3 and the motor X5. The laser machine 3 moves left and right from front to back, and performs laser cutting in sequence. The cut chain pieces are separated from the steel plate body and fall between the inclined surfaces 4a of the separation table 4, and move down along the inclined surfaces 4a. At this time, the lower part of the chain piece will be blocked by the left bottom of the inclined surface 4a on its right, and the main body of the chain piece is supported by the inclined surface of the inclined surface 4a on its left, so that the chain piece falls between the inclined surfaces 4a. When the waste material with a size much smaller than that of the chain piece is blocked by the bottom of the inclined surface 4a, due to its too small main body, it will not be supported by the side surface of the inclined surface 4a, so the waste material will pass through the separation groove 4b and fall into the collection tray on the processing table 1; the motor X5 is started to control the rotation of the brush roller 6, so that the chain pieces are collected in the collection frame 25. Therefore, using this device can conveniently collect the chain pieces and waste materials separately; at the same time, during the rotation of the brush roller 6, the hard steel wires on it can assist the chain pieces to be separated from the steel plate body, improve the blanking effect of the chain pieces, and improve the collection effect of the chain pieces.

[0034] Refer to Figures 4 - 7 It also includes: a grid plate 7, a connecting sleeve 7a, a partition plate 8, a rotating rod X9, a thread X9a, a rotating rod Y10, a thread Y10a, and a connecting rod 11; the grid plate 7 is slidably installed at the bottom of the separation table 4, the grid plate 7 moves left and right, and the grid plate 7 is misaligned with the separation groove 4b to change the passing space of the separation groove 4b; the connecting sleeve 7a is fixedly installed on the grid plate 7; the partition plate 8 is slidably installed at the bottom of the separation table 4, there are twenty partition plates 8, and the partition plates 8 can divide the space of the grid plate 7 to change the passing space formed between the grid plate 7 and the separation table 4; the rotating rod X9 is rotatably installed at the bottom of the separation table 4; the thread X9a is provided on the rotating rod X9, and the thread X9a is threadedly connected with the connecting sleeve 7a; the rotating rod Y10 is rotatably installed at the bottom of the separation table 4; the thread Y10a is provided on the rotating rod Y10, and the thread Y10a is threadedly connected with one of the partition plates 8; the connecting rod 11 is rotatably installed on each partition plate 8, and the connecting rods 11 between two adjacent partition plates 8 are rotatably connected. Therefore, when one of the connecting rods 11 rotates, all the connecting rods 11 will be synchronously controlled to rotate, so that the gaps between the partition plates 8 can change synchronously and the change amplitude is the same.

[0035] When there are differences in the production size of the chain pieces, resulting in that the size of the separation groove 4b cannot well adapt to the size of the chain pieces or waste materials, rotate the rotating rod X9 so that the thread X9a on the rotating rod X9 controls the left and right movement of the grid plate 7, rotate the rotating rod Y10, and the thread Y10a on the rotating rod Y10 controls the front and back movement of the partition plate 8. The two cooperate to increase / decrease the area of the separation groove 4b, so that the chain pieces cannot pass through the separation groove 4b while the waste materials can pass through the separation groove 4b. Therefore, this device can be adapted to the processing of chain pieces of different sizes and improve the versatility of this device.

[0036] Refer to Figures 8 - 9 Figures 8 - 9 , it further includes: mounting base 12, guide plate 12a, motor Y13, rotating shaft 13a, transmission device 14, worm sleeve rod 15, worm gear 16, cylinder 17 and support arm 17a; a guide plate 12a is fixedly installed on the right side of the separation table 4; a mounting base 12 is slidably installed on the guide plate 12a; a motor Y13 is fixedly installed on the mounting base 12; a rotating shaft 13a is fixedly installed on the output shaft of the motor Y13; a support plate is fixed on the right side of the separation table 4, and a worm sleeve rod 15 is rotatably installed on the support plate, and the rotating shaft 13a passes through the worm sleeve rod 15; a worm gear 16 is fixedly installed on the rotating rod Y10, and the worm gear 16 meshes with the worm sleeve rod 15; transmission devices 14 are fixedly installed on the rotating rod X9, the rotating shaft 13a and the worm sleeve rod 15 respectively. The transmission device 14 is specifically a kind of clutch. Among them, the transmission device 14 on the rotating shaft 13a is located between the transmission device 14 on the rotating rod X9 and the transmission device 14 on the worm sleeve rod 15. When the transmission device 14 on the rotating shaft 13a contacts the other two transmission devices 14 respectively, it will drive the rotating rod X9 to rotate respectively, or drive the worm sleeve rod 15 to rotate, and then drive the rotating rod Y10 to rotate; a cylinder 17 is fixedly installed on the right side of the separation table 4; a support arm 17a is installed on the telescopic end of the cylinder 17, and the support arm 17a is fixedly installed with the mounting base 12.

[0037] When the motor Y13 is started, it will control the transmission device 14 on the rotating shaft 13a to rotate through the rotating shaft 13a. When the telescopic end of the cylinder 17 extends, it controls the motor Y13 to move to the right, so that the transmission device 14 on the rotating shaft 13a contacts the transmission device 14 on the worm sleeve rod 15. Then the motor Y13 will control the rotating rod Y10 to rotate, so as to realize the control of the grid plate 7; and when the telescopic end of the cylinder 17 retracts, it controls the motor Y13 to move to the left, so that the transmission device 14 on the rotating shaft 13a contacts the transmission device 14 on the rotating rod X9. Then the motor Y13 will control the rotating rod X9 to rotate, so as to realize the control of the partition plate 8; the addition of the motor Y13 and the cylinder 17 makes the control of the grid plate 7 and the partition plate 8 more convenient and simple.

[0038] Refer to Figure 10 Figure 10 , it further includes: mounting plate 18, limit frame 19, right-angle abutment frame 20 and adjustment screw 20a; a mounting plate 18 is fixedly installed on the left part of the processing table 1; a limit frame 19 is slidably installed on the mounting plate 18, and the limit frame 19 slides left and right; a right-angle abutment frame 20 is slidably installed at the front and rear ends of the limit frame 19, and the right-angle abutment frame 20 slides back and forth; adjustment screws 20a are installed between the right-angle abutment frame 20 and the limit frame 19, and between the mounting plate 18 and the limit frame 19. Among them, the adjustment screw 20a between the right-angle abutment frame 20 and the limit frame 19 is threadedly connected to the limit frame 19 and rotatably connected to the right-angle abutment frame 20. The adjustment screw 20a between the mounting plate 18 and the limit frame 19 is threadedly connected to the mounting plate 18 and abuts against the limit frame 19.

[0039] After placing the steel plate, rotate the adjusting screw 20a between the mounting plate 18 and the limiting frame 19 to release the restriction on the limiting frame 19. Move the limiting frame 19 forward and backward so that the left side of the right-angle abutting frame 20 contacts the steel plate. Then reverse the adjusting screw 20a to fix the position of the limiting frame 19 again. After that, rotate the adjusting screw 20a between the right-angle abutting frame 20 and the limiting frame 19 to make the right-angle abutting frame 20 slide relative to the limiting frame 19 so that the front and rear sides of the right-angle abutting frame 20 contact the steel plate. In this way, the right-angle abutting frame 20 can stably fix the steel plate, making the position of the steel plate more stable during laser cutting and preventing the cutting quality of the chain plate from being affected due to the movement of the steel plate during cutting.

[0040] Refer to Figure 11 , it further includes: a suction device 21, a straight-through rod 22 and a contact roller 23; the suction device 21 is fixedly installed on the front side of the frame 2; the straight-through rod 22 is fixedly installed at the bottom of the frame 2, and the straight-through rod 22 communicates with the suction device 21; the contact roller 23 is rotatably installed on the straight-through rod 22, the contact roller 23 communicates with the straight-through rod 22, and the contact roller 23 can contact the steel plate.

The suction device 21 sucks the smoke generated during the laser cutting of the steel plate through the straight-through rod 22 and the contact roller 23 and collects and processes it, reducing the influence of the smoke during laser cutting and improving the processing environment of this device; at the same time, the contact roller 23 will roll and contact the steel plate when the frame 2 moves, pressing the steel plate, so that the steel plate can cooperate with the brush roller 6 to prevent the steel plate from warping and causing the laser cutting angle to tilt and affecting the cutting quality of the chain plate.
