Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and in particular to a laser cutting machine with high processing speed and a use method thereof. Background Art

[0002] Laser cutting machines focus the laser light emitted from a laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting point or boiling point, and at the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Existing steel plate laser cutting machines and laser cutting machines on the market will generate more sparks when cutting metal materials, and the sparks are easy to splash, which can easily cause fires during cutting operations and easily injure operators. Patent documents have now been made to improve this.

[0003] For example, Chinese patent CN218193134U discloses a plate laser cutting machine, which relates to the technical field of laser cutting machines and comprises a mounting base plate, a cutting table being arranged on the top surface of the mounting base plate, lateral mounting seats being arranged on both sides of the cutting table, movable slide bars being arranged on the tops of the lateral mounting seats, movable threaded rods being arranged on the bottoms of the movable slide bars, movable connecting blocks being arranged on the side walls of the movable slide bars and the movable threaded rods, control slide bars being arranged between the movable connecting blocks, control threaded rods being arranged on the bottoms of the control slide bars, control motors being arranged at one end of the control threaded rods, and movable motors being arranged at one end of the movable threaded rods, and cleaning brushes being arranged on the outer side of the laser cutting head, and when the laser cutting head cuts the plate during movement, the cleaning brushes can be used to clean the area around the cutting point to reduce impurities on the surface of the plate, thereby reducing the generation of sparks when the laser cutting head cuts the cutting point.

[0004] Although the settings in the above document can reduce sparks during cutting and clean the surrounding area, they still have obvious defects in actual use, such as:

[0005] Although the equipment can complete the cutting of the plate, it cannot load the plate when in use, and the staff needs to manually move the plate. Moreover, it is not easy to correct it after loading, and it needs to be adjusted. The whole process is too cumbersome and requires multiple staff to operate, which increases the labor cost.

[0016] The present invention also discloses a method for using a laser cutting machine with a high processing speed, which specifically comprises the following steps:

[0017] S1. Place the plate on the top of the load-bearing horizontal plate inside the loading plate platform before use, and then adjust the distance between the loading platform and the return positioning platform according to the required cutting distance of the plate. First, manually shake the threaded rotating rod to use the limit of the supporting slide to push the loading platform to move left. Stop shaking after the loading platform moves to the left to the appropriate distance, and then go to step S2;

[0018] S2. After the preparation work is completed, the motor is started to use the rotating rod to drive the third gear plate to rotate. When the third gear plate rotates, it will drive the leftmost driven rotating rod to rotate through the engagement with the first gear plate. Since several driven rotating rods are connected through pulleys and belts, several driven rotating rods drive the material guide drum to rotate. The rotation of the material guide drum pushes the plate to move to the left. The plate moves to the left through the return positioning table and contacts the material holding table. After the plate presses the button, the motor stops. At this time, the plate stops moving, and then the cylinder starts to drive the upper top plate to descend. When the upper top plate descends, it will drive the vertical pressure guide rod, L-shaped pressure seat and two telescopic pull rods to descend synchronously. When the telescopic pull rod descends, it will drive the supporting bottom frame and the top material guide drum and the first gear plate to sink. After the material guide drum sinks, it will be released from the load-bearing cross plate The inner side of the plate is disengaged, and after the material guiding drum is disengaged from the load-bearing horizontal plate, the plate is in contact with the top of the load-bearing horizontal plate and will not move. After the supporting bottom frame drops to the bottom, it will no longer sink, but the telescopic pull rod can continue to drop through the telescopic function. At this time, the third gear plate is separated from the first gear plate, and after the telescopic pull rod continues to drop, the arc surface support seat will squeeze the rectangular strip plate to allow the horizontal push rod to push the correction pressure plate to squeeze the plate, thereby correcting the front and rear position of the plate. As the supporting bottom frame drops, the L-shaped pressure seat also drops synchronously. When the bottom of the anti-rotation concave frame hits the material holding table, the L-shaped pressure seat no longer drops. At this time, the motor contacts the top of the plate, and the second gear plate meshes with the third gear plate. At this time, the upper top plate continues to drive the supporting bottom frame to drop under the sliding action of the vertical pressure guide rod. After the laser cutting head is lowered, go to step S3;

[0019] S3. After the laser cutting head is in contact with the plate, the motor is started again to drive the third gear plate to rotate. The third gear plate drives the reciprocating screw to rotate by meshing with the second gear plate. The rotation of the reciprocating screw will allow the threaded sleeve to drive the laser cutting head and the anti-rotation concave frame to move backward under the limit of the rectangular sleeve frame. At this time, the laser cutting head will cut the plate. At the same time, when the anti-rotation concave frame moves backward, the material removal push plate will flip forward and will not conflict with the plate. After the laser cutting head moves completely to the rear, the cutting of the plate is completed. At the same time, the material removal push plate and The plate is disengaged and flipped back to a vertical state. After the motor is started in reverse, the threaded sleeve moves forward and resets. At this time, the unloading push plate is resisted by the anti-rotation concave frame and will not flip backward. Therefore, it will push the cut plate forward for unloading and disengagement from the material holding table. After the threaded sleeve is completely reset, the cylinder pushes the upper plate up again to separate the second gear plate from the third gear plate, while the first gear plate engages with the third gear plate. At the same time, the material guide drum rises to lift the plate. After the motor is restarted, it will drive the material guide drum to rotate and move the plate to the left for loading. Beneficial Effects

[0020] The present invention provides a laser cutting machine with high processing speed and a method for using the same. Compared with the existing technology, it has the following beneficial effects:

[0021] (1) The laser cutting machine with high processing speed and its use method, by combining the feeding and correction mechanism and the laser cutting mechanism, the arrangement of these two mechanisms can utilize the lifting and lowering of the cylinder during use to drive the first gear plate and the second gear plate to switch and mesh with the third gear plate respectively, thereby realizing power switching, and after the switching, starting the motor can complete the loading and cutting of the plate respectively. The whole process does not require the staff to perform too much operation, effectively improving the cutting efficiency and processing speed, and meeting the current use.

[0022] (2) The laser cutting machine with high processing speed and its use method are characterized by providing a supporting bottom frame under the loading plate platform, and installing a plurality of material guiding drums on the top of the supporting bottom frame by means of a driven rotating rod, and using the supporting bottom frame in combination with a cylinder. The arrangement of these structures can allow the material guiding drums to lift the plate when the supporting bottom frame rises, so that the plate can be driven to move and load the plate after the motor is started, and can be lowered when cutting is required to allow the plate to contact the load-bearing cross plate to prevent movement, thereby ensuring stability during cutting.

[0023] (3) The laser cutting machine with high processing speed and its use method are characterized by installing a rotation-blocking recessed frame and a material unloading push plate at the bottom of the threaded sleeve by using a bent pull rod. The arrangement of these structures can allow the material unloading push plate to flip forward without interfering with the plate when the laser cutting head moves backward for cutting. After the cutting is completed, the rotation-blocking recessed frame can be used to block the material unloading push plate from flipping backward. When the threaded sleeve drives the rotation-blocking recessed frame to move forward and reset, the material unloading push plate can push the cut plate out of the material receiving table to complete the unloading. The whole process is convenient and fast.

[0024] (4) The laser cutting machine with high processing speed and its use method are characterized by installing side support plates, horizontal push rods and correction pressure plates on the surface and rear of the loading plate platform, and using them in combination with a curved surface support seat. The arrangement of these structures enables the supporting bottom frame to be lowered to the bottom, and the extension of the telescopic pull rod allows the curved surface support seat to continue to descend and squeeze the rectangular strip, so that the two correction pressure plates push the plate forward and backward for correction, so that the accuracy of the position can be ensured, and the subsequent cutting can be more precise.

[0040] The present invention discloses a method for using a laser cutting machine with a high processing speed, which specifically comprises the following steps:

[0041] S1. Before use, place the plate on the top of the load-bearing horizontal plate 103 inside the loading plate platform 102, and then adjust the distance between the material holding platform 219 and the return positioning platform 201 according to the required cutting distance of the plate. First, manually shake the threaded rotating rod 218 to use the limit of the supporting slide 217 to push the material holding platform 219 to move left. After the material holding platform 219 moves to the left to a suitable distance, stop shaking and go to step S2.

[0042] S2. After the preparation work is completed, the motor 221 is started to use the rotating rod 222 to drive the third gear plate 223 to rotate. When the third gear plate 223 rotates, it will drive the leftmost driven rotating rod 110 to rotate through the engagement with the first gear plate 114. Since the driven rotating rods 110 are connected by the pulley 112 and the belt 113, the driven rotating rods 110 drive the material guide drum 111 to rotate. The rotation of the material guide drum 111 pushes the plate to move to the left. The plate 203 moves through the return positioning table 201 and contacts the material holding table 219. After the plate presses the button 220, the motor 221 stops, and the plate stops moving. Then the cylinder 202 starts to drive the upper plate 203 to descend. When the upper plate 203 descends, it will drive the vertical pressure guide rod 204, the L-shaped pressure seat 205 and the two telescopic pull rods 115 to descend synchronously. When the telescopic pull rod 115 descends, it will drive the supporting bottom frame 109 and the top material guide drum 111 and the first gear plate 114 to sink. After the material guide drum 111 sinks, it will be lifted from the supporting bottom frame 109. The inner side of the heavy cross plate 103 is separated, and after the guide drum 111 is separated from the load-bearing cross plate 103, the plate is in contact with the top of the load-bearing cross plate 103 and will not move. After the supporting bottom frame 109 drops to the bottom, it will no longer sink, but the telescopic pull rod 115 can continue to drop through the telescopic function. At this time, the third gear plate 223 is separated from the first gear plate 114. After the telescopic pull rod 115 continues to drop, the arc surface support seat 116 will squeeze the rectangular strip 107 to allow the horizontal push rod 105 to push the correction pressure plate 106 to squeeze the plate, The front and rear positions of the plate are corrected, and the L-shaped pressing seat 205 also descends synchronously while the supporting bottom frame 109 descends. When the bottom of the anti-rotation concave frame 214 abuts against the material receiving platform 219, the L-shaped pressing seat 205 stops descending. At this time, the motor 221 contacts the top of the plate, and the second gear plate 212 is meshed with the third gear plate 223. At this time, the upper top plate 203 continues to drive the supporting bottom frame 109 to descend under the sliding action of the vertical pressure guide rod 204. After the laser cutting head 211 is lowered, the process goes to step S3.

[0043] S3. After the laser cutting head 211 is in contact with the plate, the motor 221 is started to drive the third gear plate 223 to rotate again. The third gear plate 223 drives the reciprocating screw 207 to rotate by meshing with the second gear plate 212. The rotation of the reciprocating screw 207 allows the threaded sleeve 209 to drive the laser cutting head 211 and the anti-rotation recessed frame 214 to move backward under the limit of the rectangular sleeve 210. At this time, the laser cutting head 211 will cut the plate. At the same time, when the anti-rotation recessed frame 214 moves backward, it will cause the material removal push plate 215 to flip forward and not interfere with the plate. After the laser cutting head 211 is completely moved to the rear, the cutting of the plate is completed. At the same time, the material removal push plate 215 It is separated from the plate and flipped back to a vertical state. After the motor 221 is started in reverse, the threaded sleeve 209 moves forward and resets. At this time, the unloading push plate 215 is resisted by the anti-rotation concave frame 214 and will not flip backward. Therefore, it will push the cut plate forward for unloading and disengage from the material holding table 219. After the threaded sleeve 209 is completely reset, the cylinder 202 pushes the upper plate 203 up again to separate the second gear plate 212 from the third gear plate 223, and the first gear plate 114 is engaged with the third gear plate 223. At the same time, the material guide drum 111 rises to lift the plate. After the motor 221 is restarted, it will drive the material guide drum 111 to rotate and move the plate to the left for loading.

5. The method for using a laser cutting machine with a high processing speed according to claim 4, characterized in that: The specific steps include: S1. Before use, place the plate on the top of the load-bearing horizontal plate (103) inside the loading plate platform (102), and then adjust the distance between the material receiving platform (219) and the return positioning platform (201) according to the required cutting distance of the plate. First, manually shake the threaded rotating rod (218) and use the limit of the supporting slide (217) to push the material receiving platform (219) to move left. After the material receiving platform (219) moves to the left to a suitable distance, stop shaking and go to step S2. S2. After the preparation work is completed, the motor (221) is started to use the rotating rod (222) to drive the third gear plate (223) to rotate. When the third gear plate (223) rotates, it will drive the leftmost driven rotating rod (110) to rotate through meshing with the first gear plate (114). Since the plurality of driven rotating rods (110) are connected by the pulley (112) and the belt (113), the plurality of driven rotating rods (110) drive the material guide rotating drum (111) to rotate. The rotation of the material guide rotating drum (111) pushes the plate to move to the left. The plate moves to the left and passes through The return positioning table (201) contacts the material holding table (219), and after the plate presses the button (220), the motor (221) stops, and the plate stops moving. Then the cylinder (202) starts to drive the upper plate (203) to descend. When the upper plate (203) descends, it drives the vertical pressure guide rod (204), the L-shaped pressure seat (205) and the two telescopic pull rods (115) to descend synchronously. When the telescopic pull rod (115) descends, it drives the supporting bottom frame (109) and the top material guide drum (111) and the first gear plate (114) to sink. After the material guide drum (111) sinks, The plate is detached from the inner side of the load-bearing horizontal plate (103). After the material guide drum (111) is detached from the load-bearing horizontal plate (103), the plate contacts the top of the load-bearing horizontal plate (103) and does not move. After the supporting bottom frame (109) drops to the bottom, it no longer sinks, but the telescopic pull rod (115) can continue to drop through the telescopic function. At this time, the third gear plate (223) is separated from the first gear plate (114). After the telescopic pull rod (115) continues to drop, the arc surface support seat (116) will squeeze the rectangular strip plate (107) so that the horizontal push rod (105) pushes the correction pressure plate (106) to squeeze the plate. , thereby correcting the front and rear positions of the plate, and the L-shaped pressing seat (205) also descends synchronously while the supporting bottom frame (109) descends, and when the bottom of the anti-rotation concave frame (214) abuts against the material receiving platform (219), the L-shaped pressing seat (205) no longer descends, and at this time the motor (221) contacts the top of the plate, and the second gear plate (212) is meshed with the third gear plate (223), and at this time the upper top plate (203) continues to drive the supporting bottom frame (109) to descend under the sliding action of the vertical pressure guide rod (204), and after the laser cutting head (211) is lowered, the process goes to step S3; S3. After the laser cutting head (211) is in contact with the plate, the motor (221) is started to drive the third gear plate (223) to rotate again. The third gear plate (223) drives the reciprocating screw (207) to rotate by meshing with the second gear plate (212). The rotation of the reciprocating screw (207) causes the threaded sleeve (209) to drive the laser cutting head (211) and the anti-rotation recessed frame (214) to move backward under the limit of the rectangular sleeve frame (210). At this time, the laser cutting head (211) cuts the plate. At the same time, when the anti-rotation recessed frame (214) moves backward, the material removal push plate (215) is turned forward and does not interfere with the plate. After the laser cutting head (211) is completely moved to the rear, the cutting of the plate is completed. At the same time, the material removal push plate (215) is turned forward and does not interfere with the plate. ) is separated from the plate and flipped back to a vertical state. After the motor (221) is started in the reverse direction, the threaded sleeve (209) moves forward and resets. At this time, the unloading push plate (215) is resisted by the rotation-blocking concave frame (214) and will not flip backward. Therefore, it pushes the cut plate forward for unloading and disengages from the material receiving table (219). After the threaded sleeve (209) is completely reset, the cylinder (202) pushes the upper plate (203) up again to separate the second gear plate (212) from the third gear plate (223), while the first gear plate (114) is meshed with the third gear plate (223). At the same time, the material guide drum (111) rises to lift the plate. After the motor (221) is restarted, it drives the material guide drum (111) to rotate so that the plate moves left for loading.
