Description

Technical Field

[0001] This application relates to the technical field of steel pipe cutting, and more particularly to a laser cutting and drilling device for steel pipes. Background Technology

[0002] In the field of steel pipe cutting, it is often necessary to cut long pipes into segments of specific lengths and machine the required round holes or openings on their curved sidewalls. Currently, laser cutting technology is widely used due to its high precision and good cut quality. However, when using laser cutting to cut steel pipes, the high temperature causes the metal to melt instantly, producing a large amount of molten material. This molten material drips onto the inner wall of the steel pipe, and after cooling, forms a hard slag, which seriously affects the internal quality of the workpiece and its subsequent performance.

[0003] To reduce molten material adhesion, existing technologies typically place a baffle rod inside the steel pipe to catch the molten metal generated during laser cutting. This method can, to some extent, prevent molten material from dripping directly onto the pipe wall.

[0004] However, in actual processing, the steel pipe often needs to be rotated to adjust its processing posture in order to achieve cutting at different positions. At this time, the shielding rod placed inside the pipe is prone to rolling, sliding, or shaking due to the inertia, vibration, and friction of the pipe wall caused by the rotation of the steel pipe, causing it to deviate from the intended receiving position and significantly reducing the shielding effect. Ultimately, slag will still remain on the inner wall of the pipe section, requiring an additional cleaning process, extending the processing cycle, and reducing the overall production efficiency. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, one objective of this application is to provide a steel pipe laser cutting and drilling device that can keep the shielding rod suspended and centered inside the steel pipe, thereby improving the shielding effect. It can also simultaneously remove the slag and burrs generated during cutting, simplifying subsequent processing steps and improving steel processing efficiency.

[0007] To achieve the above objectives, the first aspect of this application proposes a laser cutting and drilling device for steel pipes, comprising a cutting table, a shielding rod, two support mechanisms, a pushing component, and a clearing mechanism. The cutting table is equipped with a conveying mechanism for feeding the steel pipe, one end of which is equipped with a rotating mechanism for driving the steel pipe to rotate, and a laser cutting machine is mounted on one side of the rotating mechanism. One end of the shielding rod is suspended inside the steel pipe, and the other end of the shielding rod is threadedly connected to a guide rod, which is Z-shaped. A support plate is fixedly mounted on the cutting table, and two support mechanisms are sequentially arranged between the pushing component and the support plate. Two second limiting components of each support mechanism are symmetrically arranged on both sides of the guide rod. A linear movement mechanism is provided on the cutting table, and the pushing component is mounted on a slide of the linear movement mechanism. Toothed plates are respectively provided on both sides of the slide, and the toothed plates intermittently mesh with the support mechanisms. A rotating ring is rotatably connected within a through hole of the support plate, and two first limiting components are symmetrically arranged inside the rotating ring. The clearing mechanism is mounted on the guide rod and is located inside the rotating ring.

[0008] In addition, the steel pipe laser cutting and drilling equipment proposed in this application may also have the following additional technical features:

[0009] In one embodiment of this application, the support mechanism includes a ball screw pair, two symmetrically arranged second limiting components, and a one-way transmission component that meshes with the toothed plate. Two grooves are provided above the cutting table, and the ball screw pair is rotatably disposed within these grooves. The ball screw pair includes a ball screw and two nut sliders. The two second limiting components are respectively connected to their corresponding nut sliders. The one-way transmission component is disposed on the ball screw.

[0010] In one embodiment of this application, the second limiting component includes a second spring, a sliding plate, and a second limiting plate sleeved on a ball screw, wherein the two ends of the second spring are respectively connected to the inner wall of the nut slider and the groove; the sliding plate is disposed on the nut slider; and the second limiting plate is disposed on the sliding plate and is fitted against the guide rod.

[0011] In one embodiment of this application, the pushing component includes a driving member and a card plate, wherein the driving member is disposed on the slide; the card plate is connected to the output end of the driving member, and the card plate is provided with a card slot that matches the side wall of the pipe segment.

[0012] In one embodiment of this application, the first limiting component includes a first spring and a first limiting plate, wherein the first spring is disposed on the inner wall of the rotating ring; the first limiting plate is disposed at the end of the first spring and passes through the rotating ring, and the cross-section of the first limiting plate is trumpet-shaped.

[0013] In one embodiment of this application, the cleaning mechanism includes a drive mechanism and a grinding rod, wherein the drive mechanism is disposed at the end of the guide rod; the grinding rod is provided with a rotating shaft, the rotating shaft is connected to the drive mechanism, and the grinding rod is in contact with the inner wall of the pipe section.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] (1) By using two support mechanisms, the guide rod and the shielding rod can be stably supported, ensuring that the shielding rod is always suspended and centered inside the steel pipe, and will not shift due to the rotation or feeding of the steel pipe, thereby significantly improving the shielding effect on the molten material.

[0016] (2) The guide rod with a “Z” shaped structure can not only guide the pipe section smoothly, but also shake off the waste generated during the cutting process by taking advantage of the height difference, thereby reducing the subsequent cleaning process;

[0017] (3) By utilizing the linkage between the toothed plate and the support mechanism, automatic avoidance can be achieved when the pipe section passes through, while maintaining reliable clamping of the guide rod during non-passing phases to ensure the stability of the guide rod;

[0018] (4) The cleaning mechanism can effectively remove slag and burrs from the inner wall of the pipe section, thereby eliminating the need for subsequent separate cleaning procedures, simplifying the process flow, and improving the overall efficiency of steel pipe processing.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] The following describes the steel pipe laser cutting and drilling equipment according to an embodiment of this application with reference to the accompanying drawings.

[0030] like Figures 1 to 6 As shown, the steel pipe laser cutting and drilling equipment of this application embodiment may include a cutting table 1, a shielding rod 2, two support mechanisms 4, a pushing component 5, and a clearing mechanism 6.

[0031] The cutting table 1 is equipped with a conveying mechanism for feeding steel pipes. One end of the conveying mechanism is equipped with a rotating mechanism that drives the steel pipes to rotate, and a laser cutting machine is installed on one side of the rotating mechanism.

[0032] It should be noted that the conveying mechanism includes multiple height-adjustable conveying rollers. The steel pipes can be conveyed by the multiple conveying rollers rotating in the same direction, thus realizing the feeding action of the steel pipes.

[0033] Furthermore, the rotating mechanism includes a turntable 7, on which multiple adjustable clamping mechanisms are provided to fix the steel pipe. In the embodiments of this application, the clamping mechanism may be a three-jaw chuck. The turntable 7 is connected to an external drive mechanism (not shown in the figure). The external drive mechanism may be a gear set structure to drive the turntable 7 to rotate, thereby driving the steel pipe to rotate. It is understood that the specific structure of the clamping mechanism and the external drive mechanism is common knowledge in the art and will not be described in detail in this application.

[0034] In the embodiments of this application, the laser cutting machine emits a laser beam, and the material irradiated by the laser beam reaches the melting or vaporization temperature instantly, thereby achieving high-precision and high-efficiency cutting. The cutting path of the laser cutting machine can be controlled by a CNC center. Relevant technicians can input instructions to the CNC center through the operation panel to control the laser cutting machine to cut. It is understood that the control method and cutting path of the control center are common knowledge in the art, and will not be described in detail in this application.

[0035] One end of the shielding rod 2 is suspended inside the steel pipe, and the other end of the shielding rod 2 is threadedly connected to the guide rod 3, which is in the shape of a "Z".

[0036] It should be noted that the diameter of the shielding rod 2 is larger than the diameter of the guide rod 3, but smaller than the inner diameter of the steel pipe. The shielding rod 2 is coaxial with the steel pipe but does not contact it. When cutting the steel pipe, the shielding rod 2 remains stable and does not move with the rotation or feed of the steel pipe, thus effectively shielding the molten material, significantly improving the shielding effect and greatly reducing the generation of slag.

[0037] Furthermore, the higher end of the guide rod 3 is detachably connected to the shielding rod 2, which facilitates the replacement of the shielding rod 2. By utilizing the height difference between the two crossbars of the guide rod 3, the cut pipe section can be guided, and the waste generated by cutting the round hole can be shaken off, eliminating the need for a separate cleaning step and improving processing efficiency.

[0038] A support plate 10 is fixedly provided on the cutting table 1, and two support mechanisms 4 are arranged sequentially between the push assembly 5 and the support plate 10. The two second limiting components 42 of each support mechanism 4 are symmetrically arranged on both sides of the guide rod 3.

[0039] In the embodiments of this application, the support plate 10 is used to support the clearing mechanism 6, and the two support mechanisms 4 can respectively provide stable support for the guide rod 3, ensuring that the guide rod 3 remains in a stable suspended state.

[0040] The cutting table 1 is equipped with a linear moving mechanism 9, and the pushing component 5 is set on the slide of the linear moving mechanism 9. Toothed plates 11 are respectively provided on both sides of the slide, and the toothed plates 11 intermittently mesh with the support mechanism 4.

[0041] It should be noted that the linear moving mechanism 9 is located on one side of the conveying mechanism. The moving direction of the linear moving mechanism 9 is parallel to the axial direction of the steel pipe. The linear moving mechanism 9 can drive the pushing component 5 to move back and forth.

[0042] Furthermore, the pushing component 5 can lift the pipe section on the guide rod 3 and push it to the position of the cleaning mechanism 6, thereby facilitating the removal of slag and burrs on the inner wall of the pipe section, saving subsequent separate cleaning processes, simplifying the process flow, and improving the processing quality and efficiency of the pipe section.

[0043] In the embodiments of this application, when the toothed plate 11 moves to the position of the support mechanism 4 with the slide table, the two opposing second limiting plates 424 move away from each other and separate from the guide rod 3 with the cooperation of the toothed plate 11, automatically avoiding the pipe segment, thereby facilitating the pipe segment to pass through. At the same time, in the non-passing stage, the support mechanism 4 can maintain the reliable clamping of the guide rod 3 and ensure the stability of the guide rod 3.

[0044] A rotating ring 12 is rotatably connected inside the through hole of the support plate 10. Two first limiting components 8 are symmetrically arranged inside the rotating ring 12. The cleaning mechanism 6 is arranged on the guide rod 3 and is located inside the rotating ring 12.

[0045] It should be noted that the rotating ring 12 is connected to an external drive mechanism, which includes a motor and a gear set structure. The gear set structure is connected to the rotating ring 12. The motor drives the gear set to rotate, and the gear set drives the rotating ring 12 to rotate. (See [reference]). Figure 1 The connection method between the motor and the gear set structure is a conventional technology in this field, and will not be described in detail here.

[0046] Furthermore, the first limiting component 8 can clamp the pipe segment inside the rotating ring 12, making it easier to drive the pipe segment to rotate.

[0047] In the embodiments of this application, the cleaning mechanism 6 is disposed on the guide rod 3. When the pipe section is located inside the rotating ring 12, the cleaning mechanism 6 can grind the slag and burrs on the inner wall of the pipe section, thereby improving the quality of the inner wall of the pipe section.

[0048] To further clarify the above embodiments, in one embodiment of this application, such as Figure 5 As shown, the support mechanism 4 includes a ball screw pair 41, two symmetrically arranged second limiting components 42, and a one-way transmission component 43 that meshes with the toothed plate 11. The cutting table 1 has two grooves above it, and the ball screw pair 41 is rotatably disposed in the grooves. The ball screw pair 41 includes a ball screw and two nut sliders. The two second limiting components 42 are respectively connected to the corresponding nut sliders, and the one-way transmission component 43 is disposed on the ball screw.

[0049] It should be noted that the ball screw described in this embodiment has two sections of threads in opposite directions, and the two nut sliders are respectively set on different threads, and the nut sliders are slidably connected to the grooves. When the ball screw rotates, it can drive the two nut sliders to move towards or away from each other.

[0050] Furthermore, the one-way transmission component 43 can be a ratchet mechanism, which has the characteristic of one-way transmission, allowing the ball screw to rotate in one direction. See [reference needed]. Figure 5 When the toothed plate 11 moves to the left, it drives the one-way transmission component 43 to rotate counterclockwise. The ratchet teeth of the pawl will mesh with the inner teeth of the one-way transmission component 43, thereby driving the ball screw to rotate. Conversely, when the toothed plate 11 moves to the right, it drives the one-way transmission component 43 to rotate clockwise. The pawl can easily slide over the inclined surface of the inner teeth, and the inner and outer rings of the one-way transmission component 43 can rotate relative to each other. At this time, the ball screw no longer follows the rotation of the one-way transmission component 43. It is understood that the transmission principle of the one-way transmission component 43 in this embodiment is the prior art, and will not be described in detail in this application.

[0051] Furthermore, such as Figure 5 As shown, the second limiting component 42 includes a second spring 422, a sliding plate 423, and a second limiting plate 424 sleeved on the ball screw. The two ends of the second spring 422 are respectively connected to the nut slider and the inner wall of the groove. The sliding plate 423 is disposed on the nut slider, and the second limiting plate 424 is disposed on the sliding plate 423 and is fitted with the guide rod 3.

[0052] It should be noted that the two second limiting plates 424 are symmetrically arranged on both sides of the guide rod 3, and the side of the second limiting plate 424 that is in contact with the guide rod 3 is an arc-shaped surface. The arc-shaped surface has a larger contact area with the guide rod 3, resulting in a better clamping effect on the guide rod 3.

[0053] Furthermore, when the second limiting plate 424 is tightly attached to the guide rod 3, the second spring 422 is in a compressed state. The compressed second spring 422 has elastic potential energy, which can clamp the guide rod 3 between the two second limiting plates 424, ensuring that the guide rod 3 can be stably suspended in the air.

[0054] In one embodiment of this application, such as Figure 2 As shown, the pushing component 5 includes a driving component 51 and a card plate 52. The driving component 51 is mounted on the slide table, and the card plate 52 is connected to the output end of the driving component 51. The card plate 52 is provided with a card slot 521 that matches the side wall of the pipe section.

[0055] It should be noted that the driving component 51 can be an electric push rod. The driving component 51 is used to adjust the height of the clamping plate 52, thereby raising the pipe section to make it coaxial with the rotating ring 12. Subsequently, the linear movement mechanism 9 drives the clamping plate 52 to move, so as to push the pipe section into the rotating ring 12, which facilitates the subsequent cleaning work.

[0056] Furthermore, the slot 521 is closed at one end and open at the other, and its shape matches the contour of the pipe section sidewall, which can accurately position the pipe section and facilitate the smooth pushing of the pipe section.

[0057] In one embodiment of this application, such as Figure 5 As shown, the first limiting component 8 includes a first spring 81 and a first limiting plate 82. The first spring 81 is disposed on the inner wall of the rotating ring 12, and the first limiting plate 82 is disposed at the end of the first spring 81 and passes through the rotating ring 12. The cross-section of the first limiting plate 82 is trumpet-shaped.

[0058] It should be noted that the end of the first limiting plate 82 closest to the second limiting plate 424 expands outward to facilitate the easy insertion of the pipe section. When the pipe section is placed between the two first limiting plates 82, the first spring 81, which is in a compressed state, generates a continuous clamping force on it, thereby achieving reliable limiting of the pipe section.

[0059] In one embodiment of this application, such as Figure 6 As shown, the cleaning mechanism 6 includes a drive mechanism 61 and a grinding rod 62. The drive mechanism 61 is located at the end of the guide rod 3, and the grinding rod 62 is provided with a rotating shaft, which is connected to the drive mechanism 61. The grinding rod 62 is in contact with the inner wall of the pipe section.

[0060] It should be noted that the drive mechanism 61 may include a motor and a belt drive mechanism. One pulley is located at the output end of the motor, and another pulley is located on the rotating shaft. The motor drives the pulley to rotate, thereby driving the rotating shaft and the grinding rod 62 to rotate. During the rotation of the grinding rod 62, the inner wall of the pipe section can be ground to remove slag and burrs generated by hole cutting.

[0061] Specifically, personnel place the steel pipe to be cut on a conveying mechanism, which then feeds the pipe. After passing through the turntable 7, the pipe is secured by a clamping mechanism. Subsequently, the laser cutting machine cuts holes in the pipe and cuts it into sections. During the laser cutting process, a shielding rod 2 is suspended in the center of the inside of the pipe to catch the molten material generated during cutting, preventing it from dripping and adhering to the inner wall of the pipe.

[0062] The cut pipe segment slides down along the guide rod 3. With the help of the height difference between the two horizontal bars on the "Z"-shaped guide rod 3, the circular piece (waste material generated from cutting the circular hole) at the circular hole of the pipe segment is vibrated and falls off. The pipe segment is suspended on the guide rod 3 under the action of gravity. It should be explained that the power for the movement of the pipe segment comes from the movement of the cut end of the steel pipe. The movement of the steel pipe is used to push the pipe segment to move.

[0063] Subsequently, the relevant personnel activated the linear movement mechanism 9, which pushed the clamping plate 52 towards the pipe section. Due to the pipe section's own weight, the clamping plate 52 could be inserted into its side wall relatively smoothly. Then, the drive unit 51 controlled the clamping plate 52 to lift, raising the height of the pipe section until it was finally coaxial with the rotating ring 12. The linear movement mechanism 9 continued to push the pipe section forward.

[0064] Once one end of the pipe segment enters the funnel-shaped inlet of the second limiting plate 424, as it continues to advance, the pipe segment squeezes the second limiting plate 424 and compresses the second spring 422, thereby achieving stable clamping of the pipe segment. At the same time, the linear movement mechanism 9 drives the pushing component 5 to reset.

[0065] Once the pipe section is fully inside the rotating ring 12, the grinding rod adheres to the inner wall of the pipe section, and the external drive mechanism drives the rotating ring 12 to rotate, thereby causing the pipe section to rotate. At this time, the cleaning mechanism 6 is activated, using the rotating grinding rod 62 to grind the inner wall of the pipe section to remove slag and burrs.

[0066] It should be noted that during the movement of the linear motion mechanism 9, which pushes the clamping plate 52, the slide table drives the toothed plate 11 to move. The toothed plate 11 first engages with the one-way transmission component 43 and drives the ball screw to rotate, causing the two nut sliders to move in opposite directions and compress the second spring 422. This causes the two second limiting plates 424 to separate from the guide rod 3, releasing the constraint on the guide rod 3 and allowing the pipe section to pass through. At this time, the guide rod 3 is kept stable by another support mechanism 4. When the toothed plate 11 disengages from the one-way transmission component 43, the second spring 422 returns to its original shape and pushes the two nut sliders to move towards each other, causing the second limiting plate 424 to re-clamp the guide rod 3. Similarly, the pipe section can smoothly pass through the next second limiting plate 424, avoiding interference with the movement of the pipe section and maintaining the suspended state of the guide rod 3 and the blocking rod 2.

[0067] In summary, the steel pipe laser cutting and drilling equipment of this application embodiment can keep the shielding rod suspended and centered inside the steel pipe, thereby improving the shielding effect. It can also simultaneously remove the slag and burrs generated during cutting, simplifying subsequent processing steps and improving steel processing efficiency.
