Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting, and in particular to a multi-station intelligent laser pipe cutting machine. Background Art

[0002] Laser tube cutting machine is a kind of equipment that uses laser technology to cut tubes. It irradiates the surface of the tube with a high-energy-density laser beam, causing the tube to heat up quickly and melt and gasify, thereby achieving precise cutting of the tube. At the same time, it uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the purpose of cutting the tube.

[0003] When cutting metal pipes, existing laser tube cutting machines need to cut irregular patterns on their surfaces to meet the needs of different customers. Due to the influence of high-speed airflow, the generated sparks are easily ejected from the pipe and adhere to the surface of the laser tube cutting machine, which is difficult to clean effectively. In addition, there is a situation where the cutting waste does not fall off when the laser cuts irregular patterns. At the same time, after the metal pipe is laser cut, the metal pipe falls into the storage box by its own gravity. After the metal pipe is laser cut, its cut end has not yet solidified. If it falls directly into the storage box, it is easy to cause the cut end to deform, affecting the quality of the product. Summary of the invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that due to the influence of high-speed airflow, sparks are easily ejected from the tube and adhere to the surface of the laser tube cutting machine, which is difficult to clean effectively, and there is a problem that the cutting waste does not fall off when the laser cuts irregular patterns;

[0006] (2) How to solve the problem that after the metal pipe is cut by laser, its cut end has not yet solidified. If it falls directly into the storage box, it is easy to cause the cut end to deform and affect its product quality.

[0007] The object of the present invention can be achieved through the following technical solutions: a multi-station intelligent laser tube cutting machine, comprising a workbench and a laser tube cutter fixedly installed on the top thereof, the laser tube cutter is a prior art, and a feed opening is provided on the workbench below the laser tube cutter, a shielding mechanism for preventing sparks from splashing is provided in the feed opening, a storage mechanism for collecting formed tubes is provided below the workbench, and a guide mechanism for guiding the formed tubes is provided between the storage mechanism and the workbench;

[0008] The shielding mechanism includes a U-shaped groove fixedly connected to the inner wall of the feeding port, a first cylinder arranged longitudinally is fixedly installed on the top of the inner wall of the U-shaped groove, a scraper block for cleaning the inner wall of the U-shaped groove is fixedly installed on the protruding end of the first cylinder, and a pressing unit for assisting the shedding of cutting waste is arranged on the inner wall of the U-shaped groove on one side of the scraper block.

[0009] A further technical improvement of the present invention is that a water inlet pipe is fixedly inserted at the top of the U-shaped groove, the output end of the water inlet pipe faces the inclined surface of the scraper block, and two water spray pipes are connected to the middle of the water inlet pipe near its output end, and the output ends of the two water spray pipes are respectively facing the front and rear sides of the inner wall of the U-shaped groove.

[0010] A further technical improvement of the present invention is that a lever and a sealing plug are fixedly mounted on the extended end of the first cylinder, and the position of the sealing plug corresponds to the position of the output end of the water inlet pipe.

[0011] A further technical improvement of the present invention is that the pressing unit includes a flip frame and a U-shaped rod rotatably connected to the inner wall of the U-shaped groove, and both ends of the U-shaped rod are fixedly installed with reflection plates, and the positions of the two reflection plates correspond to the positions of the output ends of the two water spray pipes respectively; a pressing rod is fixedly installed at one end of the U-shaped rod, and the position of the pressing rod corresponds to the position of the pipe to be cut.

[0012] The further technical improvement of the present invention is that: one end of the flip frame is movably connected to the lever, and the other end of the flip frame is rotatably provided with a support roller, and the support roller is rollingly connected to one end of the U-shaped rod; clean water is sprayed from the water inlet pipe and the output ends of the two water spray pipes, and flows downward along the inner wall of the U-shaped groove to form a water wall, and the generated sparks are shielded and quickly cooled by the water wall, thereby reducing the probability of the sparks adhering to the inner wall of the U-shaped groove; before the laser tube cutter starts to cut, the extended end of the first cylinder is controlled to be extended to the longest, so that the scraper block cleans up a small amount of metal impurities adhering to the inner wall of the U-shaped groove, and the output end of the water inlet pipe is blocked by the sealing plug. At this time, the U-shaped rod is turned by the rotation of the flip frame, so that the positions of the two reflective disks correspond to the output ends of the two water spray pipes respectively, and the water sprayed from the output ends of the two water spray pipes is reflected by the corresponding reflective disks, and the clean water sprays the surface of the pipe to be cut to cool it down. At the same time, the pressing rod also rotates to provide thrust for the cutting waste that has not fallen off on the pipe to be cut, thereby assisting its falling off.

[0013] A further technical improvement of the present invention is that the guide mechanism includes a guide plate rotatably connected to the inner wall of the discharge port, the top of the guide plate is rotatably provided with a limiting roller for guiding the pipe to be cut, a positioning plate is fixedly installed at the bottom of the workbench, and a tension spring is elastically arranged between the positioning plate and the bottom of the guide plate.

[0014] A further technical improvement of the present invention is that a second cylinder arranged transversely is fixedly mounted on the positioning plate, a transmission roller is rotatably arranged on the protruding end of the second cylinder, and the position of the transmission roller corresponds to the position of the bottom of the guide plate.

[0015] A further technical improvement of the present invention is that a rubber plate for buffering the formed pipe is fixedly provided at the protruding end of the second cylinder, and the rubber plate is located below the guide plate; when the laser tube cutter cuts the pipe to be cut, the protruding end of the second cylinder is controlled to extend to the longest, and the transmission roller provides thrust to the bottom of the guide plate to make it flip over. After the cutting is completed, the formed pipe falls onto the filter plate along the guide plate and the guide trough. In the process of guiding the formed pipe, the cut end of the formed pipe faces upward to avoid collision and deformation, and water is sprayed on the cut end of the formed pipe by the water flow in the guide trough to accelerate its cooling speed. At the same time, the rubber plate provides buffering for the formed pipe, which will also reduce the falling speed of the formed pipe, further reducing the probability of deformation of the formed pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the present invention is in use, clean water is sprayed from the water inlet pipe and the output ends of the two water spray pipes, and flows downward along the inner wall of the U-shaped groove to form a water wall. The water wall shields and quickly cools the generated sparks, thereby reducing the probability of the sparks adhering to the inner wall of the U-shaped groove. Before the laser tube cutter starts to cut, the extended end of the first cylinder is controlled to be extended to the longest, so that the scraper block cleans up a small amount of metal impurities adhering to the inner wall of the U-shaped groove, and the output end of the water inlet pipe is blocked by the sealing plug. At this time, the U-shaped rod is driven to flip by the rotation of the flip frame, so that the positions of the two reflective disks correspond to the output ends of the two water spray pipes respectively, and the water sprayed from the output ends of the two water spray pipes is reflected by the corresponding reflective disks, and the clean water is sprayed on the surface of the pipe to be cut to cool it down. At the same time, the pressing rod also rotates to provide thrust for the cutting waste that has not fallen off on the pipe to be cut, thereby assisting its falling off.

[0018] When the present invention is in use, during the process of the laser tube cutter cutting the tube to be cut, the extended end of the second cylinder is controlled to extend to the longest, the transmission roller provides thrust to the bottom of the guide plate to make it flip, and the formed tube after cutting falls onto the filter plate along the guide plate and the guide trough. During the process of guiding the formed tube, the cut end of the formed tube faces upward to avoid collision and deformation, and the water flow in the guide trough sprays water on the cut end of the formed tube to accelerate its cooling speed. At the same time, the rubber plate provides buffering for the formed tube, which will also reduce the falling speed of the formed tube, further reducing the probability of deformation of the formed tube.

At this time, the flip frame 67 rotates to drive the U-shaped rod 643 to flip, so that the positions of the two reflection plates 642 correspond to the output ends of the two water spray pipes 68 respectively. The water sprayed from the output ends of the two water spray pipes 68 is reflected by the corresponding reflection plates 642, and the clean water is sprayed on the surface of the pipe to be cut to cool it down.

[0036] See also Figure 5 As shown, the extended end of the second cylinder 41 is also fixedly provided with a rubber plate 44 for buffering the formed pipe, and the rubber plate 44 is located below the guide plate 46; when the laser tube cutter 1 cuts the pipe to be cut, the extended end of the second cylinder 41 is controlled to extend to the longest, and the transmission roller 43 provides thrust to the bottom of the guide plate 46 to make it flip over. After the cutting is completed, the formed pipe falls along the guide plate 46 and the guide trough 51 onto the filter plate 52. In the process of guiding the formed pipe, the cut end of the formed pipe faces upward to avoid collision and deformation, and the water flow in the guide trough 51 sprays water on the cut end of the formed pipe to accelerate its cooling speed. At the same time, the rubber plate 44 provides buffering for the formed pipe, which will also reduce the falling speed of the formed pipe, further reducing the probability of deformation of the formed pipe.

[0039] See also Figure 1 and Figure 6 As shown, the output end of the water pump 56 is connected to the input end of the water inlet pipe 62 through the water outlet pipe 57 .

[0040] See also Figure 1 and Figure 2 As shown, a clamping tool 2 for driving the pipe to be cut is also fixedly installed on the above-mentioned workbench 3, and the clamping tool 2 is located on the side of the laser pipe cutter 1 away from the U-shaped groove 63.

[0041] Working principle: When the present invention is used, first, Figure 1 and Figure 2 As shown, the pipe to be cut is loaded into the clamping tool 2 through an external transfer device, and one end of the pipe to be cut is controlled by the clamping tool 2 to extend into the U-shaped groove 63; Figure 1 and Figure 2 As shown, the laser tube cutter 1 is turned on. At this time, the extended end of the first cylinder 61 is at its shortest, and the clamping tool 2 is used to cut irregular patterns on the surface of the tube to be cut. At the same time, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the water pump 56 is turned on, so that the clean water in the collection box 53 passes through the filtering tool 55 and is injected into the water inlet pipe 62 through the water outlet pipe 57. The clean water is sprayed out from the output ends of the water inlet pipe 62 and the two water spray pipes 68, and flows downward along the inner wall of the U-shaped groove 63 to form a water wall. In the process of cutting irregular patterns on the surface of the pipe to be cut, the sparks generated are shielded and quickly cooled by the water wall, reducing the probability of them adhering to the inner wall of the U-shaped groove 63; Figure 1-Figure 3 As shown, after the irregular pattern cutting of the surface of the pipe to be cut is completed, the clamping tool 2 controls one end of the pipe to be cut to continue to extend into the U-shaped groove 63, so that the pipe to be cut is located at the cutting position, which is convenient for the laser pipe cutter 1 to cut the pipe to be cut; Figure 1-Figure 4 As shown, before the laser tube cutter 1 starts cutting, the extended end of the first cylinder 61 is controlled to be extended to the longest, so that the scraper block 65 cleans a small amount of metal impurities attached to the inner wall of the U-shaped groove 63, and the output end of the water inlet pipe 62 is blocked by the sealing plug 66. At this time, the flip frame 67 rotates to drive the U-shaped rod 643 to flip, so that the positions of the two reflection plates 642 correspond to the output ends of the two water spray pipes 68 respectively, and the water sprayed from the output ends of the two water spray pipes 68 is reflected by the corresponding reflection plates 642, so that the clean water sprays the surface of the to-be-cut tube to cool it down. At the same time, the pressing rod 641 also rotates to provide thrust to the cutting waste that has not fallen off the to-be-cut tube to assist its falling off; Figure 1 , Figure 5 and Figure 6As shown, in the process of the laser tube cutter 1 cutting the tube to be cut, the extended end of the second cylinder 41 is controlled to extend to the longest, and the driving roller 43 provides thrust to the bottom of the guide plate 46 to make it flip over. After the cutting is completed, the molded tube falls along the guide plate 46 and the guide trough 51 onto the filter plate 52. In the process of guiding the molded tube, the cut end of the molded tube faces upward to avoid collision and deformation. The water flow in the guide trough 51 sprays water on the cut end of the molded tube to accelerate its cooling speed. At the same time, the rubber plate 44 provides a buffer for the molded tube, which will also reduce the falling speed of the molded tube, further reducing the probability of deformation of the molded tube.
