At present, the laser cutting head of the laser pipe cutting machine is time-consuming, labor-intensive and cumbersome to adjust the position according to needs. Now there are patent documents to improve this.

[0005] Although the equipment can adjust the cutting position of the laser, it is very troublesome to load the steel pipe. The steel pipe needs to be moved to the top of the equipment manually for fixing. Not only is the process cumbersome and reduces efficiency, but compared with the existing equipment that allows the steel pipe to move, it is undoubtedly cumbersome and inconvenient to adjust the laser cutting head.

[0016] The present invention also discloses a method for using a laser tube cutting machine that is convenient for loading and unloading, which specifically includes the following steps:

[0017] S1. Before use, place several steel pipes in turn on the inner sides of the groove seats on both sides. After the steel pipes are placed, start the first cylinder to descend, so that the lifting plate and the lifting rod use their own weight to drive several horizontal top plates to descend. After the lifting plate is completely dropped to the bottom and contacts the bottom plate, it will no longer descend, but the first cylinder will still push the retraction frame to slide down on the surface of the lifting rod. At this time, the arc tooth plate will mesh with the first gear under the elastic force of the first spring and drive the horizontal rotation rod to rotate. After the horizontal rotation rod rotates, it will use the conveyor belt to drive the steel pipe forward to move it to the inner side of the transmission platform, and then start the first cylinder to use the retraction frame and the lifting rod to move the steel pipe forward to the inner side of the transmission platform. The connection of the lifting rod drives the lifting plate and several horizontal top plates on the top to rise first. Since the arc tooth plate is in an arc shape, it will not mesh with the first gear, but will be squeezed back into the retraction frame. After the lifting plate rises to the top, the arc plate will contact and be squeezed with the arc stop block, so that the two lower pressure frames use the vertical support plate to push the two side rollers to close and clamp the steel pipe inside the transmission platform. At the same time, the lower roller will lift the steel pipe and separate it from the groove seat. While the lifting plate rises, the fifth spring will also be used to drive the folding plate to rise, so that the push barrel will also contact the bottom of the steel pipe. At this time, the loading of the steel pipe is completed, and then go to step S2;

[0018] S2. After the steel pipe is loaded, the motor is started and the driven rod is driven to rotate the push barrel by the transmission of the belt assembly. When the push barrel rotates, it will drive the steel pipe to move right until it passes through the worm gear. When the right end of the steel pipe contacts and presses the button, the motor is turned off. Pressing the button will also start the second cylinder. After the second cylinder is started, it will drive the laser cutting head, the pressing vertical plate, and the inclined pressure seat to descend synchronously. After the laser cutting head descends to the bottom, it will contact the surface of the steel pipe. The descending of the pressing vertical plate will press the folding plate to make it descend in the limit of the vertical pull rod, so that the push barrel no longer contacts the steel pipe. At the same time, the second gear will mesh with the third gear, and the two inclined pressure seats will squeeze the round horizontal pressure rod to allow the arc block to push the round head pressure rod to shrink to the inside of the worm gear. At the same time, the arc block will fill the side arc opening on the inner side of the cylinder frame. At this time, the clamping plate clamps the steel pipe, and then go to step S3.

[0019] S3. After the steel pipe is clamped, the motor is started again. At this time, since the push barrel descends and does not contact the steel pipe, it will not drive the steel pipe to move. The engagement of the second gear and the third gear will only drive the worm to rotate, and the rotation of the worm will drive the worm gear barrel to rotate. Since the round-headed pressure rod retracts to the inner side of the worm gear barrel, there will be no conflict. The worm gear barrel can drive the steel pipe to rotate one circle, and the steel pipe is cut off by the contact of the laser cutting head. Since the lower roller and the side roller can retract through the third spring and the second spring, the rotation of the steel pipe will not be hindered. After the steel pipe is cut off and falls, the second cylinder rises to allow the push barrel to contact the steel pipe again.

[0020] Preferably, in step S2 and step S3, the surface of the push cylinder is wrapped with a rubber layer. Beneficial Effects

[0021] The present invention provides a laser tube cutting machine that is easy to load and unload and a method for using the same. Compared with the existing technology, it has the following beneficial effects:

[0022] (1) The laser tube cutting machine and its use method, which are convenient for loading and unloading, use a loading and conveying mechanism and a position-limiting laser cutting mechanism in combination. The arrangement of these two mechanisms can utilize the lifting and lowering of the first cylinder to load the steel tube, and after the loading is completed, the steel tube can also be position-limited and clamped through the linkage between the structures. At the same time, when the steel tube is conveyed, the second cylinder is lowered by pressing the button to complete the connection with the motor power, and the laser cutting head is used to complete the cutting of the steel tube. The whole process is convenient and fast, reducing the operation of the staff and improving the laser cutting efficiency.

[0023] (2) The laser tube cutting machine and its use method, which are convenient for loading and unloading, are provided with a first gear installed on the surface of the transverse rod, and two side rollers are installed on the top of the transverse top plate by opening a rectangular groove, and used in conjunction with a lower roller. The arrangement of these structures can use the first cylinder to push the transverse top plate down, and let the arc tooth plate drive the conveyor belt to move the steel tube to the inner side of the transmission platform. After the first cylinder rises again, the arc block can be used to squeeze the arc plate, so that the side rollers and the lower roller can clamp the steel tube and lift it to limit the position.

[0024] (3) The laser tube cutting machine and its use method, which are convenient for loading and unloading, are used in combination with a second air cylinder by installing a button on the right side of the rectangular frame. The arrangement of these structures can make the vertical plate pressed down to press the folding plate after the steel tube is driven by the push barrel to press the button, so that the second gear and the third gear are engaged to complete the power docking, so that the subsequent worm gear can drive the steel tube to rotate, and the rotation of the push barrel will not affect the steel tube, thereby improving the stability of the equipment.

[0025] (4) The laser tube cutting machine and its use method, which are convenient for loading and unloading, are used by installing inclined pressure seats at both ends of the lower pressure frame in combination with a round horizontal pressure rod and an arc surface block. The arrangement of these structures can utilize the downward pressure of the inclined pressure seat to cause the arc surface block to squeeze the round head pressure rod back to the inside of the worm gear tube, and the arc surface block fills the side arc opening, so that the worm gear tube can smoothly drive the steel tube to rotate.

[0042] The present invention also discloses a method for using a laser tube cutting machine that is convenient for loading and unloading, which specifically includes the following steps:

[0043] S1. Before use, place several steel pipes in turn on the inner sides of the groove seats 107 on both sides. After the steel pipes are placed, start the first cylinder 113 to descend, so that the lifting plate 114 and the lifting rod 109 use their own weight to drive several horizontal top plates 115 to descend. After the lifting plate 114 is completely dropped to the bottom and contacts the bottom plate 101, it will no longer descend, but the first cylinder 113 will still push the retraction frame 110 to slide down on the surface of the lifting rod 109. At this time, the arc tooth plate 111 will mesh with the first gear 108 under the elastic force of the first spring 112 and drive the traverse rod 104 to rotate. After the traverse rod 104 rotates, it will use the conveyor belt 106 to drive the steel pipe forward to move it to the inner side of the transmission platform 102, and then start the first cylinder 113 to use the retraction frame 110 and the lifting rod 109. The connection of the lifting rod 109 drives the lifting plate 114 and the several horizontal top plates 115 on the top to rise first. Since the arc tooth plate 111 is in an arc shape, it will not mesh with the first gear 108, but will be squeezed back into the retraction frame 110. After the lifting plate 114 rises to the top, the arc plate 127 will contact the arc stop block 125 and be squeezed so that the two lower pressure frames 217 use the vertical support plate 118 to push the two side rollers 120 to close and clamp the steel pipe inside the transmission platform 102. At the same time, the lower roller 123 will lift the steel pipe and separate it from the groove seat 107. While the lifting plate 114 rises, it will also use the fifth spring 134 to drive the folding plate 129 to rise, so that the push cylinder 130 also contacts the bottom of the steel pipe. At this time, the loading of the steel pipe is completed, and then go to step S2;

[0044] S2. After the steel pipe is loaded, the motor 210 is started and the driven rod 131 drives the push barrel 130 to rotate by the transmission of the belt assembly 132. When the push barrel 130 rotates, it drives the steel pipe to move right until it passes through the worm gear cylinder 203. When the right end of the steel pipe contacts and presses the button 216, the motor 210 is turned off. The pressing of the button 216 also starts the second cylinder 213. After the second cylinder 213 is started, it drives the laser cutting head 215, the pressing vertical plate 212, and the inclined pressure seat 214 to descend synchronously. After the laser cutting head 215 descends to the bottom, The vertical plate 212 is pressed downward to press the folding plate 129 to make it drop in the limit position of the vertical pull rod 128, so that the push cylinder 130 is no longer in contact with the steel pipe. At the same time, the second gear 133 is meshed with the third gear 211, and the two inclined pressure seats 214 squeeze the round horizontal pressure rod 218 to make the arc block 208 push the round head pressure rod 205 to shrink to the inside of the worm gear cylinder 203. At the same time, the arc block 208 fills the side arc opening 204 on the inner side of the cylinder frame 202. At this time, the clamping plate 206 clamps the steel pipe, and then goes to step S3;

[0045] S3. After the steel pipe is clamped, the motor 210 is started again. At this time, since the push barrel 130 descends and does not contact the steel pipe, it will not drive the steel pipe to move. The engagement of the second gear 133 and the third gear 211 will only drive the worm 209 to rotate. The rotation of the worm 209 will drive the worm gear barrel 203 to rotate. Since the round-headed pressure rod 205 retracts to the inner side of the worm gear barrel 203, there will be no conflict. The worm gear barrel 203 can drive the steel pipe to rotate one circle, and the steel pipe is cut off by the contact of the laser cutting head 215. Since the lower roller 123 and the side roller 120 can retract through the third spring 124 and the second spring 121, the steel pipe will not be hindered when rotating. After the steel pipe is cut off and falls, the second cylinder 213 rises to allow the push barrel 130 to contact the steel pipe again. In steps S2 and S3, the surface of the push barrel 130 is wrapped with a rubber layer.

5. The method for using a laser tube cutting machine that is convenient for loading and unloading according to claim 4 is characterized in that: The specific steps include: S1. Before use, a plurality of steel pipes are placed in sequence on the inner sides of the groove seats (107) on both sides. After the steel pipes are placed, the first cylinder (113) is started to descend, so that the lifting plate (114) and the lifting rod (109) use their own weight to drive a plurality of horizontal top plates (115) to descend. After the lifting plate (114) is completely lowered to the bottom and contacts the bottom plate (101), it will no longer descend. However, the first cylinder (113) will still push the retraction frame (110) to slide down on the surface of the lifting rod (109). At this time, the arc tooth plate (111) will mesh with the first gear (108) under the elastic force of the first spring (112) and drive the traverse rod (104) to rotate. After the traverse rod (104) rotates, it will use the conveyor belt (106) to drive the steel pipe forward to move it to the inner side of the transmission platform (102). Then, the first cylinder (113) is started again to use the retraction frame (110) and the lifting rod (109). The connection of the lifting rod (109) drives the lifting plate (114) and several horizontal top plates (115) at the top to rise first. Since the arc tooth plate (111) is arc-shaped, it will not mesh with the first gear (108), but will be squeezed back into the retraction frame (110). After the lifting plate (114) rises to the top, the arc plate (127) will contact the arc stop block (125) and be squeezed so that the two lower pressure frames (217) use the vertical support plate (118) to push the two side rollers (120) together to clamp the steel pipe inside the transmission platform (102). At the same time, the lower roller (123) will lift the steel pipe and separate it from the groove seat (107). While the lifting plate (114) rises, it will also use the fifth spring (134) to drive the folding plate (129) to rise, so that the push cylinder (130) also contacts the bottom of the steel pipe. At this time, the loading of the steel pipe is completed, and then go to step S2; S2. After the steel pipe is loaded, the motor (210) is started and the driven rod (131) is driven by the belt assembly (132) to drive the push barrel (130) to rotate. When the push barrel (130) rotates, it drives the steel pipe to move right until it passes through the worm gear barrel (203). When the right end of the steel pipe contacts and presses the button (216), the motor (210) is turned off. The pressing of the button (216) also activates the second cylinder (213). After the second cylinder (213) is activated, it drives the laser cutting head (215), the pressing vertical plate (212), and the inclined pressure seat (214) to descend synchronously. After the laser cutting head (215) descends to the bottom, The push plate (129) contacts the surface of the steel pipe, and the downward pressure of the vertical plate (212) presses the folding plate (129) to make it descend in the limit position of the vertical pull rod (128), so that the push cylinder (130) no longer contacts the steel pipe. At the same time, the second gear (133) meshes with the third gear (211), and the two inclined pressure seats (214) squeeze the round horizontal pressure rod (218) to allow the arc block (208) to push the round head pressure rod (205) to shrink into the inside of the worm gear cylinder (203). At the same time, the arc block (208) fills the side arc opening (204) on the inner side of the cylinder frame (202). At this time, the clamping plate (206) clamps the steel pipe, and then goes to step S3; S3, after the steel pipe is clamped, the motor (210) is started again. At this time, since the push barrel (130) descends and does not contact the steel pipe, it will not drive the steel pipe to move. The meshing of the second gear (133) and the third gear (211) will only drive the worm (209) to rotate. The rotation of the worm (209) will drive the worm gear barrel (203) to rotate. Since the round head pressure rod (205) retracts to the inner side of the worm gear barrel (203), no conflict occurs. The worm gear barrel (203) can drive the steel pipe to rotate one circle. The steel pipe is cut off by the contact of the laser cutting head (215). Since the lower roller (123) and the side roller (120) can be retracted by the third spring (124) and the second spring (121), the steel pipe will not be hindered when rotating. After the steel pipe is cut off and falls, the second cylinder (213) rises to allow the push barrel (130) to contact the steel pipe again.

6. The method for using a laser tube cutting machine that is convenient for loading and unloading according to claim 5 is characterized in that: In step S2 and step S3, the surface of the pushing cylinder (130) is wrapped with a rubber layer.
