Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a metal pipe laser cutting machine for a shipyard. Background Art

[0002] During the shipbuilding process, shipyards often use laser cutting machines (such as plasma arc welding machines) to cut raw materials such as metal pipes used in shipbuilding, so that the metal pipes are cut to the required size for use.

[0003] When cutting metal pipes, laser cutting machines usually use a mechanism that can clamp and position cylindrical workpieces such as metal pipes to clamp and fix them in place, avoiding displacement of the pipe during the cutting process and causing deviations in the cutting position. Since a large amount of debris is bound to appear during the cutting process, these debris will generate extremely high temperatures under the influence of the laser cutting machine. After falling from the metal pipe, they are likely to stick to the parts of the clamping and positioning mechanism (such as screws), causing the screw to get stuck during the subsequent rotation and adjustment process. This needs to be improved. Summary of the invention

[0010] The bottom end of the material placing tray is in a concave state, a pump body is arranged in the concave part, and the water outlet part of the pump body is fixedly connected to the liquid guiding tube.

[0011] The side wall of the material placing tray is provided with a plurality of liquid inlets for the welding anti-splash agent in the liquid storage tank to enter the concave part of the material placing tray, and the liquid inlets are all provided with filter screens for filtering welding slag debris.

[0016] In the present invention, by controlling the rotation of the sleeve on the surface of the threaded rod, the limiting ring is lifted upward, causing the clamping plate to rotate around the fixed column and clamp the metal pipe. Since the part of the metal pipe to be cut is at its bottom, it is possible to prevent the chips generated by cutting from falling onto the threaded rod and rendering the threaded rod unusable.

[0017] By controlling the pump body, the welding anti-spatter agent in the liquid storage tank is guided through the liquid guide pipe and the stainless steel corrugated hose into the spray plate, and is sprayed onto the inner wall of the metal pipe through the spray plate, carrying away the welding slag chips that enter the metal pipe during the welding process. This not only prevents the welding slag chips from sticking to the inner wall of the metal pipe, but also prevents these chips from sticking to the spray plate, the supporting block or other components.

[0018] During the cutting of the metal pipe, the material placing disk is driven to rotate in the liquid storage tank. At this time, the welding slag adsorbed on the surface of the filter screen in the liquid inlet can be scraped off by the scraping plate, facilitating the entry of the welding anti-spatter agent in the liquid storage tank into the pump body through the liquid inlet.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 10, the present invention provides a technical solution: a laser cutting machine for metal pipes in a shipyard, including a base 1. A cutting machine 45 is arranged on the base 1. The cutting machine 45 is made of a plasma arc welding machine of the prior art. A hydraulic push rod is arranged at the bottom end of the cutting machine 45 to facilitate adjusting the height of the cutting machine 45 for use. A lifting chute is arranged on the base 1. A rotating gear disk 3 is arranged at the top end of the lifting chute. A square clamping block is arranged at the bottom end of the rotating gear disk 3. A square clamping groove matching the square clamping block is arranged at the top end of the threaded column 4, which is convenient for pulling out the rotating gear disk 3 later to disconnect its contact with the first driving gear 7. The threaded column 4 penetrates through the top plate of the lifting chute and is rotatably installed on the inner wall of the bottom end of the lifting chute. A slider 5 is movably sleeved on the outer wall of the threaded column 4. The length and width dimensions of the slider 5 are the same as those of the lifting chute. A material supporting table 6 is fixedly installed on the slider 5. A supporting component 20 is arranged at the top end of the material supporting table 6. A metal pipe 46 is movably sleeved on the supporting component 20. A supporting platform 2 is fixedly installed on the base 1. A through hole is arranged on the supporting platform 2. The metal pipe 46 can extend above the supporting platform 2 through the through hole. A first driving gear 7 meshing with the rotating gear disk 3 is arranged at the top end of the supporting platform 2. The first driving gear 7 is composed of a rotating motor and a toothed ring. The toothed ring is fixedly sleeved on the outer wall of the output shaft of the rotating motor. The toothed ring meshes with the rotating gear disk 3. By controlling the first driving gear 7 to drive the rotating gear disk 3 to rotate, at this time, the slider 5 on the threaded column 4 moves vertically up and down in the lifting chute, so that the material supporting table 6 can move vertically up and down. A clamping component is arranged at the top end of the supporting platform 2. A circular groove is arranged at the top end of the supporting platform 2. A sliding block adapted to it is slidably installed in the circular groove. A ring 8, which is one of the clamping components, is fixedly installed at the top end of the sliding block. A belt 9 is jointly sleeved on the ring 8 and the first driving gear 7. The belt 9 is located at the part of the output shaft of the rotating motor, which is one of the components of the first driving gear 7 and is not blocked by the toothed ring. That is, during the rotation of the first driving gear 7, the first driving gear 7 drives the ring 8 to rotate through the belt 9 during the rotation process, which is convenient for driving the metal pipe 46 to rotate and perform circular cutting during the cutting process.

[0032] On the outer wall of the circular ring 8, two L-shaped extension blocks 10 are fixedly installed. The bottom ends of the extension blocks 10 are movably attached to the belt 9. At the top ends of the extension blocks 10, two fixing columns 11 are fixedly installed respectively. On the outer walls of the two fixing columns 11, clamping plates 12 are movably sleeved. At the top ends of the clamping plates 12, mounting frames 13 and first guiding plates 15 are fixedly installed respectively. The top plate of the first guiding plate 15 is arc-shaped, which is convenient for guiding the metal pipe 46 through the support table 2. On the mounting frames 13, coating cloths 14 are fixedly installed respectively. The coating cloths 14 extend out of the mounting frames 13. After the coating cloths 14 absorb the welding anti-spatter agent, when the metal pipe 46 passes through the through hole on the support table 2, the welding anti-spatter agent on the coating cloths 14 will be wiped onto the surface of the metal pipe 46, avoiding the chips generated during the cutting process from sticking to the surface of the metal pipe 46. On the outer wall of the circular ring 8, two bump blocks 16 are also fixedly installed. At the top ends of the two bump blocks 16, threaded rods 17 are fixedly installed respectively. On the outer walls of the two threaded rods 17, sleeves 18 are movably sleeved. The top ends of the two sleeves 18 are jointly rotatably connected to a limiting ring 19. The four first guiding plates 15 are all located in the inner ring of the limiting ring 19.

[0033] When the metal pipe 46 passes through the through hole on the support table 2, it is guided by the first guiding plate 15 and then passes through the through hole of the support table 2. By controlling the rotation of the sleeve 18 on the surface of the threaded rod 17, the limiting ring 19 is lifted upward. During the upward movement, the inner wall of the limiting ring 19 pushes the first guiding plate 15 to generate displacement, that is, the clamping plate 12 at the bottom end of the first guiding plate 15 rotates around the fixing column 11 and clamps the metal pipe 46, clamping and fixing the position of the metal pipe 46. At this time, the threaded rod 17 is directly above the part of the metal pipe 46 to be cut, which can effectively prevent the chips generated during the cutting process from sticking to the threaded rod 17 and affecting the use of the threaded rod 17.

[0034] The support assembly 20 includes a liquid reservoir 22, which is fixedly mounted on the top of the support platform 6. The liquid reservoir 22 can store welding anti-splash agent. A material placing tray 21 is arranged in the liquid reservoir 22, and the material placing tray 21 is rotatably mounted in the liquid reservoir 22. A positioning column 23 is arranged at the center position of the top of the material placing tray 21. A plurality of fixed plates 24 are fixedly mounted on the outer wall of the positioning column 23. A slide groove is arranged on the top of the fixed plate 24. A sliding plate 25 is slidably mounted in the slide groove. The sliding plate 25 is connected to the inner wall of the slide groove by a reset spring. A linkage column 26 is fixedly mounted on the top of the sliding plate 25. A second guide plate 27 is also arranged on the top of the sliding plate 25. The second guide plate 27 is rotatably connected to the sliding plate 25 by a torsion spring. When the metal tube 46 moves downward through the second guide plate 27, the second guide plate 26 is fixedly mounted on the top of the sliding plate 25. The guide plate 27 is fitted just above the linkage column 26 to prevent the second guide plate 27 from rotating excessively and failing to guide the displacement of the metal tube 46. A linkage ring 29 is rotatably installed on the outer wall of the positioning column 23. A plurality of toggle blocks 30 for toggling the linkage column 26 to produce displacement are arranged on the outer wall of the linkage ring 29. One side of the toggle block 30 is arranged as an arc surface to facilitate fitting the linkage column 26 and toggling it to produce displacement. A second drive gear 28 having the same structure as the first drive gear 7 is also arranged at the top of the material placing tray 21. A plurality of teeth that can mesh with each other are arranged on the outer walls of the second drive gear 28 and the linkage ring 29. A frequency converter with a locking function needs to be installed on the rotating motor that is one of the components of the second drive gear 28, so that the second drive gear 28 can be in a locked state after stopping.

[0035] When the metal tube 46 passes through the through hole on the support platform 2 and continues to move downward, the metal tube 46 is first guided downward by the second guide plate 27 until it fits the top plate of the material placing tray 21. When the second driving gear 28 rotates to make the linkage ring 29 rotate, the toggle block 30 located on the linkage ring 29 will rotate with it. During the rotation, the toggle block 30 pushes the linkage column 26 to move, so that the sliding plate 25 located at the bottom end of the linkage column 26 moves translationally until it fits the inner wall of the metal tube 46, thereby fixing the position of the bottom end of the metal tube 46.

[0036] The top end of the positioning column 23 is fixedly installed with a threaded fixing column 31. A sleeved cylinder 32 is movably sleeved on the outer wall of the threaded fixing column 31. A tapered column 39 is arranged inside the sleeved cylinder 32. The bottom end of the tapered column 39 is fixedly connected to the threaded fixing column 31 through a plurality of vertical rods 40. An installation ring 33 is rotatably installed on the outer wall of the sleeved cylinder 32. A plurality of grooves are arranged at the top end of the installation ring 33. Rotating shafts 34 are rotatably installed in the grooves. The rotating shafts 34 are connected to the inner walls of the grooves through torsion springs, enabling the prying plate 35 to rotate downward and closely adhere to the tapered column 39. Prying plates 35 and linkage plates 36 are fixedly installed on the outer walls of the plurality of rotating shafts 34. Supporting blocks 37 and spraying plates 38 are fixedly installed on the linkage plates 36. The plurality of spraying plates 38 are all hollow plates. One side side wall of the spraying plate 38 is an arc surface, and a plurality of spraying through holes are arranged on this side side wall and communicate with the hollow part inside the spraying plate 38. A liquid guide pipe 41 is arranged inside the installation ring 33. The liquid guide pipe 41 is connected to the plurality of spraying plates 38 through stainless steel corrugated hoses 42. The bottom end of the middle material placing plate 21 is in a concave state, and a pump body is arranged inside. The pump body can be made of a water pump in the prior art. The liquid guide pipe 41 passes through the tapered column 39, the threaded fixing column 31, the positioning column 23, and the middle material placing plate 21 and is connected to the water outlet of the pump body, facilitating the transportation of the welding anti-spatter agent to the spraying plate 38 and spraying it to coat the inner wall of the metal pipe 46, preventing the debris generated during the cutting process from adhering to the inner wall of the metal pipe 46 after melting due to high temperature and affecting the subsequent use of the metal pipe 46.

[0037] Control the downward rotation of the sleeved cylinder 32 according to the inner diameter of the metal pipe 46 to be cut. Since the position of the tapered column 39 is fixed, when the sleeved cylinder 32 drives the installation ring 33 to rotate downward, the prying plate 35 rotates due to the position limitation provided by the tapered column 39, changing the position of the supporting block 37 until it is the same as the inner diameter of the metal pipe 46, facilitating the inner wall support of the metal pipe 46 by the plurality of supporting blocks 37. At this time, the pump body guides the welding anti-spatter agent in the liquid storage tank 22 into the spraying plate 38 through the liquid guide pipe 41 and the stainless steel corrugated hose 42 and sprays it onto the inner wall of the metal pipe 46.

[0038] A plurality of liquid inlets 43 are arranged on the outer wall of the material placing tray 21, and a filter screen is arranged on each of the liquid inlets 43. The filter screen can be used to filter the welding slag in the welding anti-splash agent. A scraper 44 is fixedly installed on the inner wall of the liquid storage tank 22, and the scraper 44 fits the filter screen, and a plurality of rubber thin rods are arranged on its surface. When the metal tube 46 is clamped by the clamping plate 12 on the circular ring 8, the circular ring 8 rotates following the first driving gear 7 through the belt 9, so that the metal tube 46 rotates following the circular ring 8. Because the sliding plate 25 supports the inner wall of the metal tube 46, the material placing tray 21 can be driven to rotate in the liquid storage tank 22 when the metal tube 46 is not cut off. At this time, the welding slag adsorbed on the surface of the filter screen in the liquid inlet 43 can be scraped off by the scraper 44, so that the welding anti-splash agent in the liquid storage tank 22 can enter the pump body through the liquid inlet 43.

[0039] When the present invention is used, the electrical appliance on the base 1 is first started by an external power supply, and the sleeve 32 is controlled to rotate downward according to the inner diameter of the metal tube 46. When the sleeve 32 drives the mounting ring 33 to rotate downward, the prying plate 35 is restricted by the conical column 39 to rotate, so that the position of the support block 37 changes until it is the same as the inner diameter of the metal tube 46, so that the support block 37 can support the inner wall of the metal tube 46, and the metal tube 46 passes through the through hole on the support platform 2, and is guided by the first guide plate 15 and then passes through the support platform 2. The first drive gear 7 drives the rotating toothed disc 3 to rotate, and the threaded column 4 causes the support platform 6 to move downward during the rotation process until the metal tube 46 to be cut is at the same horizontal position as the cutting machine 45, and then the rotating toothed disc 3 is removed. In the process of the metal tube 46 moving downward, the welding anti-splash agent on the smear cloth 14 will be wiped onto the surface of the metal tube 46, and then the sleeve 18 is controlled to rotate on the surface of the threaded rod 17 to make the limit ring 19 move downward. The first guide plate 15 is lifted up, and the inner wall of the limit ring 19 pushes the first guide plate 15 to move during the rising process, that is, the clamping plate 12 at the bottom end of the first guide plate 15 rotates around the fixed column 11 and clamps the metal tube 46, and controls the second driving gear 28 to rotate, so that the linkage ring 29 rotates, and the toggle block 30 located on the linkage ring 29 rotates with it, and during the rotation process, the toggle block 30 pushes the linkage column 26 to move, so that the sliding plate 25 at the bottom end of the displacement linkage column 26 moves in translation until it fits the inner wall of the metal tube 46, The position of the tube 46 is fixed, and the metal tube 46 can be cut by the cutting machine 45. At this time, the first driving gear 7 drives the ring 8 to rotate through the belt 9. The ring 8 drives the metal tube 46 to rotate during the rotation to perform a ring cutting operation. In the cutting process, the welding anti-splash agent in the liquid storage tank 22 is guided into the spray plate 38 through the liquid guide tube 41 and the stainless steel corrugated hose 42 by controlling the pump body, and is sprayed onto the inner wall of the metal tube 46 through the spray plate 38, taking away the welding slag debris entering the metal tube 46 during the welding process.

[0040] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
