Description

Technical Field

[0001] This invention relates to the field of steel pipe processing technology, specifically to a laser cutting and drilling device for steel pipes. Background Technology

[0002] Traditional steel pipe cutting and drilling methods primarily employ sawing and drilling, which suffer from low processing accuracy, large heat-affected zones, and susceptibility to mechanical stress and surface damage for small-diameter, thin-walled, and irregularly shaped pipes, failing to meet the ever-increasing demands for precision machining. Laser processing, as a non-contact advanced manufacturing technology, offers significant advantages such as small kerf, high precision, small heat-affected zone, no mechanical stress, and flexible processing capabilities, and is gradually being introduced into the pipe processing field.

[0003] Patent application CN202311741739.3 relates to the field of laser cutting technology and proposes a steel pipe laser cutting device, including a frame and a laser cutting head, as well as a feeding box, a unloading mechanism, a feeding mechanism, and a cooling mechanism. The feeding box is movably mounted on one side of the frame, and the bottom of the feeding box is connected to an unloading pipe. The unloading mechanism is located at the outlet of the unloading pipe and is used to control the unloading of the steel pipe. The feeding mechanism is used to push the steel pipe to the laser cutting position. The feeding mechanism includes a receiving plate, a pushing plate, a clamping assembly, and a baffle. The receiving plate has a groove. The pushing plate is movably mounted on the side of the feeding box away from the frame. The clamping assembly is mounted on the pushing plate and is used to clamp the steel pipe. The baffle is movable and mounted on the side of the receiving plate away from the feeding box. The cooling mechanism is used to cool the cut steel pipe. Through the above technical solution, the problems of inconvenient automatic loading and unloading and the impact of the heated steel pipe after processing on subsequent processing in the prior art are solved.

[0004] However, when the patent cuts off one end of the steel pipe, the cut portion of the pipe material mainly relies on passive receiving during the feeding process, resulting in collision damage to the cut pipe material.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a steel pipe laser cutting and drilling device that can effectively solve the above-mentioned technical problems.

[0010] Furthermore, both the slider and the connecting plate are slidably connected to the sliding frame via an adjustment cavity; multiple sets of fixing components are provided.

[0011] Furthermore, the first fixing sleeve is connected to an air tube one and an air tube two; a sliding sleeve is slidably connected to the first fixing sleeve.

[0012] Furthermore, a retaining plate is fixedly installed on the sliding sleeve; a baffle is slidably installed on the retaining plate; a pull rod is fixedly installed on the baffle; a second fixing sleeve is slidably installed on the pull rod; a third air pipe is connected to the second fixing sleeve; a stop block is detachably installed on the sliding sleeve; a blowpipe is connected to the sliding sleeve; and a first spring is fixedly installed on the sliding sleeve.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a laser cutting and drilling device for steel pipes. After the steel pipe is processed, the fixing component is reset, and the air pipe continues to supply air into the fixing sleeve. The air enters the telescopic rod two through the pressure valve. After the pressure inside the telescopic rod two increases, it is discharged through another set of pressure valves. At this time, the air supply from the air pipe stops, and the reset spring inside the telescopic rod two resets, causing the air to be discharged through the pressure valve. Then, the telescopic rod two drives the fixing sleeve one and the connecting component two to rotate through the rotating shaft, so that the steel pipe on the long shaft moves synchronously. Then, when the air in the fixing sleeve one is discharged, the sliding sleeve resets under the action of the spring one, and synchronously drives the top head to reset, so that the steel pipe falls from the long shaft into the collection frame, completing the collection of the steel pipe.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 9 As shown, the present invention discloses a steel pipe laser cutting and drilling device, comprising: a machine base 1; a support assembly 2 installed on the machine base 1; a fixing mechanism 4 for fixing the steel pipe; a moving assembly 3 for moving the fixing mechanism 4; and a laser cutting head 5 installed on the fixing mechanism 4. The steel pipe is manually fed to ensure that it is supported by the support mechanism, and the moving assembly 3 moves the fixing mechanism 4. One end of the steel pipe is fixed by the fixing mechanism 4 so that after the steel pipe is cut, the cut steel pipe is fixed by the fixing mechanism 4, and then the laser cutting head 5 cuts the steel pipe. After cutting, the fixing mechanism 4 can prevent the cut steel pipe from falling directly, causing deformation of the steel pipe and damage to the equipment.

[0023] In detail, the moving component 3 includes: a cylinder 31 fixedly installed on the machine base 1; a slider 32 fixedly installed on the cylinder 31; and a sliding rod 33 fixedly installed on the machine base 1. The sliding rod 33 is slidably connected to the slider 32. The cylinder 31 drives the slider 32 to slide on the sliding rod 33, thereby driving the fixing mechanism 4 to move as a whole. The fixing mechanism 4 is installed on the slider, and the movement of the slider can drive the fixing mechanism 4 to move.

[0024] The support assembly 2 includes: a support frame 21; a lifting rod 22 fixedly mounted on the support frame 21; a fixed frame 23 fixedly mounted on the lifting rod 22; a rotating frame 24 fixedly mounted on the fixed frame 23; a rotating frame 25 rotatably mounted on the rotating frame 24; a motor 26 fixedly mounted on the fixed frame 23; a gear 27 fixedly mounted on the motor 26; a telescopic rod 28 fixedly mounted on the rotating frame 25; a fixing block 210 fixedly mounted on the telescopic rod 28; a clamp 211 fixedly mounted on the fixing block 210; and a limiting frame 29 fixedly mounted on the rotating frame 25. The gear 27 meshes with the rotating frame 25; a limiting hole 212 is provided on the rotating frame 25; the limiting frame 29 is slidably connected to the telescopic rod 28; and the support frame 21 is fixedly mounted on the machine base 1.

[0025] The support assembly 2 is provided with two sets. The steel pipe is inserted through the limiting hole 212, and then the telescopic rod 28 drives the fixing block 210 to move. The telescopic rod 28 and the fixing block 210 are also provided with two sets. The two sets of fixing blocks 210 drive the clamp 211 to fix the steel pipe. When the fixing block 210 moves, the limiting frame 29 limits the movement of the telescopic rod 28 to prevent the fixing block 210 and the clamp 211 from shaking and affecting the fixation of the steel pipe.

[0026] It should be added that after the steel pipe is fixed by the clamp 211, the motor 26 is started to drive the gear 27 to rotate, which in turn drives the rotating frame 25 to rotate on the rotating frame 24, so that the steel pipe is fixed and then rotated. In the rotating state, the steel pipe works with the laser cutting head 5 to adjust the cutting and drilling positions.

[0027] The telescopic pole 128 can be equipped with either a hydraulic cylinder or an electric telescopic pole.

[0028] The fixing mechanism 4 includes: a fixing frame 41; a fixing component 42 installed on the fixing frame 41; and a collection frame 43 fixedly installed on the fixing frame 41. The fixing frame 41 is fixedly connected to a slider 32. When the slider 32 slides on the slide rod 33 under the action of the cylinder 31, it drives the fixing frame 41 to move, thereby driving the fixing component 42 and the collection frame 43 to move synchronously. The fixing component 42 can fix the end of the steel pipe. The cut steel pipe is fixed by the fixing component 42 and placed inside the collection frame 43 after rotation, avoiding direct drop that would cause the cut steel pipe to deform and affect recycling. Similarly, the steel pipe hitting the surface of the device would also cause the surface of the machine to vibrate, affecting the service life of the device.

[0029] The fixing assembly 42 includes: a fixing head 421, which is fixedly mounted on the fixing frame 41; a connector 422 fixedly mounted on the fixing head 421; a rotating shaft 423 rotatably mounted on the connector 422; a connector 424 fixedly mounted on the rotating shaft 423; a fixing sleeve 425 fixedly mounted on the connector 424; a support plate 426 fixedly mounted on the fixing sleeve 425; and a telescopic rod 427 fixedly mounted on the support plate 426. The telescopic rod 427 is rotatably connected to the fixing head 421. When the telescopic rod 427 extends or retracts, it pulls the fixing sleeve 425 through the support plate 426 and moves it through the connector 424. The connector 424 rotates with the connector 422 through the rotating shaft 423, causing the fixing sleeve 425 to rotate, which facilitates the cutting of the steel pipe.

[0030] In detail, the fixing component 42 also includes: a long shaft 428 installed on the fixing sleeve 425; a fixing member 429 for fixing the steel pipe; a top head 4282 fixedly installed on the long shaft 428; multiple sets of top heads 4282 are provided on the long shaft 428, so that when fixing the steel pipe, the long shaft 428 is inserted into the steel pipe, and the end of the steel pipe is fixed by the fixing member 429.

[0031] Because the inner diameter of the steel pipes is different, it is difficult to support the inside of the steel pipes using the long shaft 428. Therefore, the expansion of the top head 4282 can support the inside of the steel pipes and ensure the fixing effect. The top head 4282 is an airbag. When the part of the steel pipe that needs to be cut is located deep inside the steel pipe, the long shaft 428 needs to be inserted deep into the steel pipe. The position of the fixing member 429 also needs to be adjusted. The long shaft 428 is provided with a sliding groove 4281. The fixing member 429 slides on the long shaft 428 through the sliding groove 4281, so that the long shaft 428 can enter deep into the steel pipe, which facilitates the support of the inside of the steel pipes.

[0032] It should be noted in detail that the fixing component 429 includes: a second slider 4291, which is slidably connected to a slide groove 4281; a sliding frame 4292 fixedly mounted on the second slider 4291; an adjustment cavity 4293 formed on the sliding frame 4292; a second cylinder 4294 fixedly mounted on the sliding frame 4292; a connecting plate 4295 fixedly mounted on the second cylinder 4294; a limiting head 4296 fixedly mounted on the connecting plate 4295; and a limiting head 4296 fixedly mounted on the connecting plate. Rack 4297 on 4295; Gear 4298 meshing on rack 4297; Rack 4299 meshing on gear 4298; Slider 42910 fixedly mounted on rack 4299; Limiting head 42911 fixedly mounted on slider 42910; Spring 42912 fixedly mounted on sliding frame 4292; Slider 42910 and connecting plate 4295 are slidably connected to sliding frame 4292 through adjusting cavity 4293.

[0033] During use, the fixing frame 41 moves towards the end of the steel pipe, allowing the long shaft 428 to enter the interior of the steel pipe. Then, the sliding frame 4292 contacts the end of the steel pipe. At this time, the fixing frame 41 continues to move according to the cutting position. Under the reaction force of the end of the steel pipe, the sliding frame 4292 drives the second slider 4291 to slide inside the sliding groove 4281, thereby achieving position adjustment. At this time, the long shaft 428 moves inside the steel pipe. It should be noted that the long shaft 428 will not get stuck at the cut, but will stop before reaching the cut. After the position is appropriate, the second cylinder 4294 is activated to drive the connecting plate 4295 to move down. The first limiting head 4296 presses down and fixes the outer wall of the steel pipe. When the connecting plate 4295 moves, it slides in the adjusting cavity 4293. The adjusting cavity 4293 limits the movement of the connecting plate 4295 to prevent it from shaking during movement.

[0034] Additionally, when the connecting plate 4295 moves, it drives the rack 4297 to move. The rack 4297 drives the gear to rotate, which drives the rack 4299 to move. The rack 4299 drives the slider 4291 to slide in the adjusting cavity 4293, which drives the limit head 42911 to move upward and cooperate with the limit head 4296 to lock the end of the steel pipe, ensuring the fixation of the steel pipe. Moreover, multiple sets of fixing members 429 are provided, which can improve the fixation of the end of the steel pipe. When the slider 4291 slides inside the slide groove 4281, it drives the spring 42912 to deform. When the steel pipe is no longer in contact with the sliding frame 4292, the spring 42912 resets, driving the sliding frame 4292 to reset, which is convenient for subsequent use.

[0035] The fixed sleeve 425 is connected to an air pipe 4251 and an air pipe 4252; a sliding sleeve 4253 is slidably connected to the fixed sleeve 425; an air pipe 42913 is connected to the sliding frame 4292; a blowpipe 42537 is connected to the sliding sleeve 4253; and a spring 42538 is fixedly installed on the sliding sleeve 4253.

[0036] When processing steel pipes, molten slag adheres to the inner wall of the pipe, reducing its quality. This application uses a long shaft 428 to support the pipe inside, preventing molten slag from entering. However, due to different inner diameters of the steel pipes, the long shaft 428 cannot adapt to various inner diameters, resulting in molten slag inside the pipe. Therefore, when cutting the steel pipe, this application uses a blowpipe 42537 to simultaneously blow protective gas into the processing position inside the pipe. This improves the cutting effect of the laser cutting head 5 on the steel pipe, prevents molten slag from entering the inner wall of the pipe, and assists in cooling the pipe.

[0037] Specifically, protective gas is introduced into the fixed sleeve 425 through the air pipe 4251, and then into the sliding sleeve 4253 and discharged through the blowpipe 42537. The sliding sleeve 4253 is slidably connected to the fixed sleeve 425 and the long shaft 428. By adjusting the position of the sliding sleeve 4253 within the fixed sleeve 425 and the long shaft 428, the position of the blowpipe 42537 can be adjusted so that the blowpipe 42537 always maintains air blowing to the processing position.

[0038] It should be added that a retaining plate 42531 is fixedly installed on the sliding sleeve 4253; a baffle 42532 is slidably installed on the retaining plate 42531; a pull rod 42533 is fixedly installed on the baffle 42532; a fixed sleeve 42534 is slidably installed on the pull rod 42533; an air pipe 42535 is connected to the fixed sleeve 42534; a stop block 42536 is detachably installed on the sliding sleeve 4253. When the slider 42910 slides in the adjusting cavity 4293, the gas in the compressed adjusting cavity 4293 is input into the air pipe 42535 through the air pipe 42913, thereby driving the pull rod 42533 to slide inside the fixed sleeve 42534, pushing the baffle 42532 to move on the retaining plate 42531, so that the baffle 42532 isolates the inside of the sliding sleeve 4253. When the gas inside the sliding sleeve 4253 cannot circulate, air is supplied to the fixed sleeve 425 through the air pipe 4251. This gas pushes the sliding sleeve 4253 to slide within the fixed sleeve 425, and moves the blowpipe 42537, allowing the position of the end of the blowpipe 42537 to be adjusted. During adjustment, the spring 42538 deforms under force. When the sliding sleeve 4253 needs to be reset, the gas inside the fixed sleeve 425 is discharged. At this time, the spring 42538 resets, causing the sliding sleeve 4253 to reset (when the sliding sleeve 4253 resets, the stop block 42536 abuts against the long shaft 428, which is considered as the reset being completed. The position of the stop block 42536 can be adjusted and installed on the sliding sleeve 4253). After the adjustment is completed, the blowpipe 42537 slides out from the positioning hole 4283 and matches the processing area. Protective gas is blown out through the blowpipe 42537, improving the processing effect on the steel pipe.

[0039] When the steel pipe is fixed, the baffle 42532 is opened, and protective gas can be output from the sliding sleeve 4253 and the blowpipe 42537. When the steel pipe is not fixed, the baffle 42532 divides the inside of the sliding sleeve 4253 and adjusts the position of the sliding sleeve 4253. When the sliding sleeve 4253 is adjusted, the sliding sleeve 4253 pushes the gas inside the long shaft 428 to compress. Since the mandrel 4282 is connected to the long shaft 428, the compressed gas enters the inside of the mandrel 4282, causing the mandrel 4282 to expand and fix the steel pipe.

[0040] Finally, air pipe 2 4252 is connected to telescopic rod 2 427. Air pipe 2 4252 is equipped with a pressure valve, and telescopic rod 2 427 is equipped with another set of pressure valves. After the steel pipe is processed, the fixing part 429 is reset, and air pipe 1 4251 continues to supply air into the fixing sleeve 1 425, so that the gas enters the telescopic rod 2 427 through the pressure valve. After the pressure inside the telescopic rod 2 427 increases, it is discharged through the other set of pressure valves. At this time, the air supply from air pipe 1 4251 is stopped, and the reset spring inside the telescopic rod 2 427 resets, causing the gas to be discharged through the pressure valve. Then, the telescopic rod 2 427 drives the fixing sleeve 1 425 and the connecting part 2 424 to rotate through the rotating shaft 423, so that the steel pipe on the long shaft 428 moves synchronously. Then, when the gas in the fixing sleeve 1 425 is discharged, the sliding sleeve 4253 is reset under the action of spring 1 42538, which synchronously drives the top head 4282 to reset, so that the steel pipe falls from the long shaft 428 into the collection frame 43, completing the collection of the steel pipe.

[0041] After the long shaft 428 rotates, the end face of the steel pipe falls into the collection frame 43, shortening the distance between the steel pipes falling into the collection frame 43, reducing the impact of the steel pipes on the device, and preventing the cylindrical surface of the steel pipe from hitting the collection frame 43, which would cause the steel pipe to deform and affect the recycling of the steel pipe, thereby reducing processing costs and achieving cost reduction and efficiency improvement.

[0042] During use, air is supplied to the fixed sleeve 425 through the air pipe 4251. At this time, the fixing component 429 is not fixed to the steel pipe, and the baffle 42532 blocks the gas from escaping, thereby adjusting the position of the sliding sleeve 4253. When the sliding sleeve 4253 moves, on the one hand, the blowpipe 42537 moves out to better blow protective gas to the processing position and prevent slag from sticking to the inner wall of the steel pipe. On the other hand, it pushes the gas in the long shaft 428 into the mandrel 4282, which assists in fixing the steel pipe. After the position of the sliding sleeve 4253 is adjusted, the steel pipe is fixed by the fixing component 429. At this time, the baffle 42532... As the steel pipe moves, gas is discharged through the blowpipe 42537 to protect the processing area. After cutting, the fixing part 429 stops fixing the steel pipe. The cut steel pipe is fixed on the long shaft 428 through the top head 4282. Then, gas continues to be supplied into the fixing sleeve 425, so that the gas is discharged through another set of pressure valves. The return spring in the telescopic rod 427 resets and drives the gas to be discharged through the pressure valve. Thus, the fixing sleeve 425, the connecting part 424 and the rotating shaft 423 rotate, so that the steel pipe on the long shaft 428 rotates synchronously and drives the steel pipe to fall from the long shaft 428 into the collection frame 43, completing the collection of the steel pipe.

[0043] The long shaft 428 has a positioning hole 4283 at its end. The blowpipe 42537 slides out through the positioning hole 4283. The positioning hole 4283 limits the movement of the blowpipe 42537 to prevent it from shaking.
