Description

Technical Field

[0001] This invention relates to the field of metal pipe processing technology, specifically to a continuous feeding metal pipe laser cutting processing device. Background Technology

[0002] Metal pipe fittings are a collective term for pressure-bearing components used in piping systems for connection, turning, diameter reduction, diversion, sealing, and support. They are mainly made of carbon steel, stainless steel, alloy steel, cast iron, and non-ferrous metals such as copper. They are characterized by high strength and resistance to high pressure and high temperature. Common types include elbows, tees, crosses, reducers, flanges, pipe caps, and pipe clamps. Connection methods include butt welding, socket welding, threaded connections, and flange connections. They are widely used in petrochemical, power, shipbuilding, urban water supply and drainage, and HVAC engineering fields.

[0003] In traditional tube laser cutting equipment, the feeding process generally adopts a ramp or chain conveyor structure. This type of method relies heavily on gravity or simple mechanical pushing. Round tube profiles are prone to continuous rolling between ramps or chain links, causing multiple tubes to roll down and stack at the same time, making it difficult to achieve stable interval batch feeding. On the other hand, multiple tubes squeeze and push against each other, and are prone to jamming when encountering slight deformation or uneven surface of the tube. This not only disrupts the cutting cycle but also requires frequent manual intervention, which seriously restricts the automation level and continuous operation efficiency of the equipment.

[0004] Based on this, the present invention designs a continuous feeding metal tube laser cutting processing device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous feeding metal tube laser cutting processing device to solve the problems mentioned in the background art, which are that the feeding process of traditional tube laser cutting equipment adopts a ramp or chain conveyor structure, which easily leads to the rolling and stacking of round tubes.

[0013] As a further embodiment of the present invention, the lead screw is rotatably connected to the fixed cylinder through a bearing and is located in the slide groove. A material discharge port is provided above the fixed cylinder. Guide grooves are provided on the lower part of the V-groove plate and on the upper part of the slide groove. The movable block slides in the slide groove. The electromagnetic seat and the limiting plate are designed in an inverted U-shape and are fitted on the mounting frame. The mounting frame and the electromagnetic seat are slidably engaged with the guide groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention activates a drive motor, which drives the drive wheel to rotate via a secondary connecting shaft. During this process, the drive wheel, driven wheel, and toothed belt work together to drive the main connecting shaft, causing the movable cylinder to rotate within the outer casing. Simultaneously, the connector at one end of the movable cylinder rotates on a fixed ring. Since the fixed cylinder is fixed to the fixed ring, relative rotation occurs between the movable and fixed cylinders. As the movable cylinder rotates, metal tubing is continuously inserted from the filling port into the remaining storage compartments of the movable cylinder. Meanwhile, the traction rods on the traction plates at one end of multiple fixed rods slide within the annular groove. The continuously rotating movable cylinder, by driving the through rods, causes multiple end-to-end interlocking arc-shaped plates to rotate together on the main connecting shaft. This causes the spherical blocks at one end of the through rods to slide one by one from the smooth section of the cam ring into the protrusion. During this process, the traction rods gradually move from the annular groove to the section connecting with the groove. The protrusion pushes the spherical blocks at one end of the through rods, causing the through rods to pass through the connecting hole. The curved plate slides on the main connecting shaft, and the moving curved plate can synchronously drive the wedge block, causing the wedge block to slide between the two connecting plates. During this process, the push rods on both sides of the wedge block can push against the inclined groove wall of the inclined groove, causing the movable frame and the connecting plate as a whole to move upward along the connecting groove. As the movable frame moves upward, the traction rod gradually slides from the limiting groove into the inclined top groove, and then the continuously moving movable frame pushes the traction rod through the inclined groove wall of the inclined top groove, causing the traction rod to drive the traction plate and the fixed rod to rotate together. This causes the two baffles that form a V-shaped structure to flip open synchronously under the action of the fixed rod. At this time, the bottom of the storage tank is no longer blocked by the baffle, and the metal pipes fall smoothly from the drop port into the V-groove plate in the fixed cylinder under the action of gravity, thus completing the automatic feeding. This realizes the intermittent batch feeding of large batches of pipes, solving the problem that traditional inclined or chain feeding is prone to multiple pipes rolling down at the same time or being squeezed and jammed due to gravity. It realizes the continuous and stable feeding of metal pipes and ensures work efficiency.

[0015] 2. This invention utilizes a V-groove plate within a fixed cylinder to automatically receive and center metal pipe fittings falling from the discharge port into the fixed cylinder, preventing deflection during descent. The main electric push rod is then activated, causing the auxiliary electric push rod to move the electromagnetic base upwards, bringing it into contact with the metal pipe fitting and securing it. Next, the power motor is activated, rotating the lead screw, which in turn drives a movable block to slide horizontally within the groove. This moving block simultaneously moves the mounting frame and the electromagnetic base along the guide groove. The adsorbed metal pipe is conveyed to the outlet of the fixed cylinder. At this time, the main electric push rod is activated, which pushes the pressure plate down, causing the pressure plate to press and fix the metal pipe. Then, the working motor and laser cutting head are started, which drives the gear to rotate. The meshing of the gear and the gear ring causes the movable sleeve on the fixed ring to move in a circle, thereby driving the laser cutting head to rotate and cut around the metal pipe. Through the cooperation between the V-groove plate, the electromagnetic seat and the pressure plate, the metal pipe is positioned and stably fixed, thus preventing the pipe from accidentally sliding or shifting during cutting.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 The present invention provides a technical solution: A continuous feeding metal pipe laser cutting processing device includes an outer shell 1, a filling port 2 on the top of the outer shell 1, a drive motor 3 fixedly installed on one side of the outer shell 1, a protective shell 4 fixedly connected to the other side of the outer shell 1, a fixed ring 5 fixedly connected to one side of the inner side of the outer shell 1, a movable sleeve 8 rotatably connected to one side of the fixed ring 5 via a bearing, a movable cylinder 9 rotatably installed on the other side of the fixed ring 5, a working motor 43 fixedly installed on one side of the protective shell 4, a secondary connecting shaft 44 connected to the output shaft of the working motor 43, the secondary connecting shaft 44 rotatably connected to the protective shell 4 via a bearing, a gear 45 fixedly installed on the secondary connecting shaft 44, a gear ring 46 fixedly connected to the movable sleeve 8, a laser cutting head 47 fixedly installed inside the movable sleeve 8, and the gear 45 and the gear ring 46 meshing with each other and both being located inside the protective shell 4.

[0021] During operation, the working motor 43 is started, which drives the gear 45 to rotate through the secondary connecting shaft 44. The meshing of the gear 45 and the gear ring 46 causes the movable sleeve 8 to move in a circular motion on the fixed ring 5, thereby driving the laser cutting head 47 to rotate and cut around the metal pipe. The protective shell 4 can protect the gear 45 and gear ring 46 inside, reducing the direct contact between the gear 45 and gear ring 46 and the outside.

[0022] An annular groove 6 and a recessed groove 7 are formed on the inner wall of the outer casing 1. The recessed groove 7 is located above the annular groove 6 and the annular groove 6 and the recessed groove 7 are connected. A fixed cylinder 10 is fixedly connected to the fixed ring 5. A connecting piece 11 is fixedly connected to one side of the movable cylinder 9 and is rotatably connected to the fixed ring 5. A main connecting shaft 12 is fixedly connected to the other end of the movable cylinder 9. Six storage troughs 13 are evenly spaced on the wall of the movable cylinder 9. Fixed rods 14 are rotatably connected to both sides of the movable cylinder 9 below the storage troughs 13 via bearings. A baffle 15 is fixedly connected to the fixed rod 14. A traction plate 16 is fixedly connected to one end of the fixed rod 14 through the wall of the movable cylinder 9. A traction rod 17 is fixedly connected to one side of the traction plate 16. The movable cylinder 9 is located around the main connecting shaft 12. Multiple connecting slots 18 are provided at equal intervals. A movable frame 19 is slidably installed on the movable cylinder 9 through the connecting slots 18. Connecting plates 20 are fixedly connected to both sides of the lower part of the movable frame 19. Inclined top slots 21 are provided on both sides of the movable frame 19. The inclined top slots 21 on both sides of the movable frame 19 together form an inverted V-shaped structure. A limiting slot 22 is provided at one end of the inclined top slot 21 of the movable frame 19. A connecting strip 23 is fixedly connected to one side of the connecting plate 20. Both the connecting slot 18 and the connecting strip 23 are T-shaped. The connecting strip 23 slides with the connecting slot 18. An inclined slot 24 is provided on the connecting plate 20. One end of the inclined top slot 21 is connected to the limiting slot 22. The traction rod 17 slides with the inclined top slot 21 and the limiting slot 22. The end of the traction rod 17 slides in the annular groove 6.

[0023] When the movable frame 19 and the connecting plate 20 move as a whole, the connecting bar 23 can slide in the connecting groove 18. The T-shaped design of the connecting groove 18 and the connecting bar 23 guides and restricts the movement of the movable frame 19 and the connecting plate 20, preventing the movable frame 19 and the connecting plate 20 from shifting or moving during movement. The annular groove 6 can limit the sliding traction rod 17 inside, preventing accidental swaying.

[0024] The outer casing 1, the movable cylinder 9, and the fixed cylinder 10 are in close contact with each other. The fixed cylinder 10 is located inside the movable cylinder 9. A discharge port 25 is fixedly connected to one side of the fixed cylinder 10, and a fastener 26 is fixedly connected to the other side of the fixed cylinder 10. A main electric push rod 27 is fixedly installed inside one side wall of the fixed cylinder 10. A pressure plate 28 is fixedly connected to the movable end of the main electric push rod 27. A V-groove plate 30 is fixedly connected inside the fixed cylinder 10. A sliding groove 31 is opened at the bottom of the fixed cylinder 10. A power motor 32 is fixedly installed on one side of the fixed cylinder 10 located in the sliding groove 31. A lead screw 33 is connected to the output shaft of the power motor 32. A movable block 34 is threadedly installed on the lead screw 33. An installation frame 35 is fixedly connected to the top. An auxiliary electric push rod 36 is fixedly installed inside the installation frame 35. The movable end of the auxiliary electric push rod 36 passes through the installation frame 35 and is fixedly connected to an electromagnetic base 37. Limiting plates 38 are fixedly connected to both sides of the electromagnetic base 37. The lead screw 33 is rotatably connected to the fixed cylinder 10 through bearings and is located in the slide groove 31. A material discharge port 59 is opened above the fixed cylinder 10. Guide grooves 60 are opened on the groove wall below the V-groove plate 30 and above the slide groove 31. The movable block 34 slides in the slide groove 31. The electromagnetic base 37 and the limiting plate 38 are designed in an inverted U-shape and are fitted into the installation frame 35. The installation frame 35 and the electromagnetic base 37 are slidably engaged with the guide grooves 60.

[0025] During operation, the power motor 32 rotates the lead screw 33, which drives the movable block 34 to slide within the slide groove 31. The sliding movable block 34 can simultaneously drive the mounting frame 35 and the electromagnetic seat 37 to slide along the guide groove 60. The guide groove 60 guides the movable block 34 and the mounting frame 35 as a whole, preventing accidental twisting or tilting during movement. The auxiliary electric push rod 36 can push the electromagnetic seat 37 to adjust its working position. The electromagnetic seat 37 and the limiting plate 38 are fitted together in an inverted U-shape on the mounting frame 35, and the contact between the walls provides limiting guidance, ensuring the stability of the electromagnetic seat 37's movement.

[0026] The output shaft of the drive motor 3 is connected to a secondary connecting shaft 39. Six arc-shaped plates 48 are slidably mounted on the secondary connecting shaft 39 in a centrally symmetrical manner. A fitting block 49 is fixedly connected to one side of the arc-shaped plate 48, and a fitting groove 50 is opened on the other side of the arc-shaped plate 48. A through rod 51 is fixedly connected to the arc-shaped plate 48, and a wedge block 52 is fixedly connected above the arc-shaped plate 48. Push rods 53 are fixedly connected to both sides of the wedge block 52. The fitting block 49 and the fitting groove 50 slide in cooperation. The six arc-shaped plates 48 are connected end to end by the fitting block 49 and the fitting groove 50 to form a complete annular clamping structure. The wedge block 52 slides between the two connecting plates 20, and the push rod 53 slides in the inclined groove 24.

[0027] Through the sliding connection between the fitting block 49 and the fitting groove 50, multiple arc plates 48 can be inserted end to end to form a continuous ring-shaped integral sleeve on the secondary connecting shaft 39. The sliding of the fitting block 49 in the fitting groove 50 not only ensures the relative position of the multiple arc plates 48 is stable, but also restricts the movement of the arc plates 48, ensuring the stability of the movement of the arc plates 48.

[0028] A cam ring 29 is fixedly connected to one side wall of the fixed cylinder 10. A fixing member 26 is rotatably connected to the wall of the movable cylinder 9. The cam ring 29 is located inside the fixing member 26. A protrusion 54 is provided on the cam ring 29. A stop plate 55 is fixedly connected to the edge of the cam ring 29 and the protrusion 54. The secondary connecting shaft 39 is rotatably connected to the wall of the outer casing 1 through a bearing. A drive wheel 40 is fixedly installed at one end of the secondary connecting shaft 39. The main connecting shaft 12 is rotatably connected to the outer casing 1 through a bearing. A driven wheel 4 is fixedly installed at one end of the main connecting shaft 12. 1. The driving wheel 40 and the driven wheel 41 are jointly equipped with a toothed belt 42. Multiple connecting holes 56 are equally spaced on one side wall of the movable cylinder 9. The through rod 51 passes through the connecting holes 56 and is slidably connected to the movable cylinder 9. A spherical block 57 is fixedly connected to one end of the through rod 51. A return spring 58 is sleeved on the through rod 51. The spherical block 57 abuts against the cam ring 29 and slides between the two stop plates 55. One end of the return spring 58 is fixedly connected to the end of the through rod 51, and the other end of the return spring 58 is fixedly connected to the wall of the movable cylinder 9.

[0029] When the spherical block 57 at the end of the through rod 51 slides along the cam ring 29, the cam ring 29 and the stop plate 55 on the edge of the protrusion 54 can limit the spherical block 57 to prevent the spherical block 57 from accidentally slipping off. When the protrusion 54 pushes the spherical block 57 to make the through rod 51 slide, the through rod 51 can compress the return spring 58, and then the elastic rebound of the return spring 58 assists the return movement of the through rod 51 and the arc plate 48.

[0030] Working principle of this invention: By inserting the metal pipe through the filling port 2 on one side of the outer shell 1, the inserted metal pipe can directly enter the storage tank 13 on the movable cylinder 9 and be blocked by two baffles 15 that together form a V-shaped structure. Then, the drive motor 3 is started, and the drive motor 3 drives the drive wheel 40 to rotate through the auxiliary connecting shaft 39. During the process, the main connecting shaft 12 is driven by the cooperation between the drive wheel 40, the driven wheel 41 and the toothed belt 42, so that the main connecting shaft 12 drives the movable cylinder 9 to rotate inside the outer shell 1. At this time, the connector 11 at one end of the movable cylinder 9 rotates on the fixed ring 5. Since one end of the fixed cylinder 10 is fixed on the fixed ring 5, the movable cylinder 9 and the fixed cylinder 10 rotate relative to each other. During the rotation of the movable cylinder 9, metal pipes are continuously inserted from the filling port 2 into the remaining storage tank 13 of the movable cylinder 9. The traction rods 17 on the traction plate 16 at one end of the multiple fixed rods 14 can slide in the annular groove 6. The continuously rotating movable cylinder 9 can drive the through rod 51 to make the multiple end-to-end inserted arc plates 48 rotate together on the main connecting shaft 12, causing the spherical blocks 57 at one end of the multiple through rods 51 to slide from the smooth section of the cam ring 29 into the protrusion 54 one by one. During this process, the traction rod 17 gradually moves from the annular groove 6 to the section connecting with the groove 7. The protrusion 54 can push the spherical block 57 at one end of the through rod 51, causing the through rod 51 to pass through the connecting hole 56 and push the arc plate 48 to slide on the main connecting shaft 12. The moving arc plate 48 can simultaneously drive the wedge block 52, causing the wedge block 52 to slide between the two connecting plates 20. During this process, the push rods 53 on both sides of the wedge block 52 can push the inclined groove wall of the inclined groove 24, causing the movable frame 19 and the connecting plate 20 as a whole to move upward along the connecting groove 18. As the movable frame 19 moves upward, the traction rod 17 gradually slides from the limiting groove 22 into the inclined top groove 21, causing the continuously moving movable frame 19 to push the traction rod 17 through the skewed groove wall of the inclined top groove 21. This causes the traction rod 17 to drive the traction plate 16 and the fixed rod 14 to rotate together, so that the two baffles 15 forming a V-shaped structure are simultaneously flipped open under the action of the fixed rod 14. At this time, the bottom of the storage tank 13 loses the obstruction of the baffle 15, and the metal pipe falls smoothly from the discharge port 59 into the V-groove plate 30 in the fixed cylinder 10 under the action of gravity, thus completing the automatic feeding. Then, the auxiliary electric push rod 36 is activated, which pushes the electromagnetic seat 37 to move upward in the guide groove 60, causing the electromagnetic seat 37 to contact the metal pipe and adsorb and fix the pipe. Then, the power motor 32 is activated, which drives the movable block 34 to slide horizontally in the slide groove 31 through the lead screw 33. The moving movable block 34 can synchronously drive the mounting frame 35 and the electromagnetic seat 37 to move together along the guide groove 60, thereby conveying the adsorbed metal pipe to the outlet 25 of the fixed cylinder 10. At this time, the main electric push rod 27 is activated, which pushes the pressure plate 28 downward, causing the pressure plate 28 to press and fix the metal pipe to prevent slippage and displacement. Then, the working motor 43 and the laser cutting head 47 are activated, so that the working motor 43 drives the gear 45 to rotate through the secondary connecting shaft 44. Then, by using the meshing of the gear 45 and the gear ring 46, the movable sleeve 8 moves in a circle on the fixed ring 5, thereby driving the laser cutting head 47 to rotate and cut around the metal pipe, thus completing the cutting operation.
