Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a non-standard pipeline cutting and opening device. Background Art

[0002] Laser pipe cutting is a process that uses a high-energy laser beam to irradiate the surface of the pipe. The high energy density, high focus and high-speed mobility of the laser beam can quickly melt, vaporize or reach the ignition point of the pipe. At the same time, the laser beam is moved at a certain speed to complete the entire pipe cutting and hole opening process. Compared with traditional pipe cutting, it has high cutting accuracy and fast cutting speed. However, when the laser head cuts the metal pipe, under the thermal effect of the laser head, trace metal molten droplets will be generated at the incision of the metal pipe. The metal molten droplets condense into metal residues and adhere to the inner wall of the processed metal pipe. It is not easy to clean and will affect the subsequent application of the pipe.

[0038] like Figure 1-Figure 11 As shown, a non-standard pipe cutting and opening device includes a laser cutting machine body, including:

[0039] A load-bearing seat 1 is arranged on the laser cutting machine body, and a through hole 11 is arranged on the load-bearing seat 1;

[0040] The support tube 2 has a mounting ring plate 21 fixedly connected to the bottom, and the mounting ring plate 21 is fixedly connected to one side of the through hole 11;

[0041] The suction sleeve group 3 is fixedly connected in the support tube 2, and a pneumatic telescopic component 4 is fixedly connected to the mounting ring plate 21. The telescopic end of the pneumatic telescopic component 4 is fixedly connected to the suction sleeve group 3, and the end of the suction sleeve group 3 is externally connected to a dust removal mechanism;

[0042] An inner wall scraping mechanism 5 is arranged on the front end of the suction sleeve group 3;

[0043] A suction port 34 is provided on the suction sleeve group 3, and an auxiliary cleaning mechanism 8 is fixedly connected to the suction port 34, and the auxiliary cleaning mechanism 8 is transmission-connected to the inner wall scraping mechanism 5 at the front end;

[0044] The load-bearing seat 1 is fixedly connected with an electromagnetic valve group 9, one end of which is transmission-connected with the pneumatic telescopic assembly 4, the suction sleeve group 3 and the inner wall scraping mechanism 5, and the other end of which is externally connected with an air pump.

[0045] In this embodiment, the air pump is a conventional device, and the dust removal mechanism is also a conventional mechanism, such as a cyclone dust removal mechanism. In actual operation, the air pump can be connected to the solenoid valve group 9 and the dust removal mechanism by adapting the gas passages as needed. Similarly, the air pump, as a power output source, can generate negative pressure in the movable tube 33 by outputting gas and regulating the solenoid valve, so that the suction port 34 can inhale air, remove the debris, and enter the dust removal mechanism. At the same time, the output end of the air pump is also divided into a plurality of air passages connected to the solenoid valve group 9, and through the control of the solenoid valve group 9, the first telescopic cylinder 41 and the second telescopic cylinder 63 can be extended and retracted, and the air slip ring 51 can also be rotated, so that a single air pump can achieve multiple drive requirements.

[0046] Before cutting the pipe to be processed, there may be oxide film, oil stains and other dirt inside the pipe. These dirts will affect the cutting quality during the laser cutting process, resulting in the generation of inner wall residues. For example, oxide film and oil stains may generate local high temperature under the irradiation of laser beam, thereby aggravating the formation of residues. Therefore, the second telescopic cylinder 63 extends, and then the inner wall scraping mechanism 5 goes deep into the pipe to be cut. Then the second telescopic cylinder 63 contracts, so that the scraper 7 contacts the inner wall of the pipe, drives the air slip ring 51 to rotate, drives the movable pipe 33 to rotate, and then the inner wall scraping mechanism 5 cleans and scrapes the inner wall of the pipe to ensure the quality of pipe cutting, and the suction port 34 and the dust removal mechanism work normally to suck out the cleaned things. In addition, in the process of laser cutting of heavier metal pipes, especially when the cutting is close to completion, the metal pipe may move under its own weight when there is a little left after cutting. The first telescopic cylinder 41 is contracted to prevent the edge of the scraper 7 from contacting the laser to be cut. The inner wall scraping mechanism 5 expands and contacts the metal pipe as a support, and the air slip ring 51 synchronizes the rotation of the metal pipe on the other side to complete the final cutting of the metal pipe.

[0047] After the inside of the pipe is cleaned, the pneumatic telescopic assembly 4 is driven to retract the first telescopic cylinder 41, so that the scraper 7 does not contact the inner wall of the pipe, and one of the scrapers 7 is located directly above to block the sputtered metal residues. At the same time, the suction port 34 is also located directly above, and the laser cutting of the pipe is started. At this time, the telescopic state of the first telescopic cylinder 41 is synchronously retracted and extended according to the forward and backward movement of the laser cutting head, so that the suction port 34 is always located directly below the laser cutting head to suck in the sputtered debris and ensure the quality of pipe processing.

[0048] After each laser cutting process on the pipeline, there will be sticky debris remaining on the inner wall of the air outlet of the movable tube 33 and the inner wall of the suction hood 81. Therefore, each time the inner wall scraping mechanism 5 expands and contracts, the auxiliary cleaning mechanism 8 will be linked to clean the debris on the inner wall, and the debris on the scraper 7 will also be rubbed and removed when cleaning the next pipeline to be processed.

[0049] As an optional implementation, Figure 6 , 7 As shown in , 8 and 9, the suction sleeve group 3 includes a limiting tube 31 fixedly connected to the support tube 2, a limiting portion 311 is fixedly connected to the inner side of the top of the limiting tube 31, an exhaust pipe 32 is slidably connected to the inner side of the limiting tube 31, a limited protrusion 321 is fixedly connected to the tail of the exhaust pipe 32, a movable tube 33 is rotatably connected to the tail of the exhaust pipe 32, the suction port 34 is arranged on the movable tube 33, and the pneumatic telescopic assembly 4 includes three first telescopic cylinders 41 fixedly connected to the mounting ring plate 21, and the telescopic ends of the three first telescopic cylinders 41 are fixedly connected to the transmission ring plate 42, and the transmission ring plate 42 is fixedly connected to the movable tube 33;

[0050] In this way, the extension and retraction of the first telescopic cylinder 41 can drive the transmission ring plate 42 to move forward and backward, and the forward and backward movement of the transmission ring plate 42 will pull the exhaust pipe 32 forward or backward, thereby pulling the movable pipe 33 rotatably connected to the exhaust pipe 32 forward or backward, so as to move forward or backward in the pipe to be cut without affecting the suction of debris.

[0051] As an optional implementation, Figure 1 , 2As shown in FIG. 3 , the inner wall scraping mechanism 5 comprises an air slip ring 51 whose inner circular end is fixedly connected to the movable tube 33, the base of the air slip ring 51 is fixedly connected to the transmission ring plate 42, the rotating inner circular end of the air slip ring 51 is fixedly connected to the outer circular end of the movable tube 33, the outer circular end of the top of the movable tube 33 is fixedly connected to a mounting sleeve 52, and three movable bracket groups 53 are fixedly connected to the outer wall of the mounting sleeve 52 at equal circumferences, each of the movable bracket groups 53 is transmission-connected to a telescopic transmission assembly 6, and a scraper 7 is fixedly connected to the top of each movable bracket group 53;

[0052] In this way, the extension and retraction of the telescopic transmission assembly 6 will pull the three movable bracket groups 53 to expand and contract simultaneously, causing the three scrapers 7 to move simultaneously.

[0053] As an optional implementation, Figure 3 , 7 As shown, the movable bracket group 53 includes a bottom hinge bracket 531 fixedly connected to the sleeve, and the front and rear ends of the bottom hinge bracket 531 are respectively hinged with a front hinge bracket 532 and a rear hinge bracket 533, and the top of the front hinge bracket 532 and the top of the rear hinge bracket 533 are hinged with an upper hinge bracket 534, the top of the front hinge bracket 532 is hinged to the front end of the upper hinge bracket 534, the top of the rear hinge bracket 533 is hinged to the rear end of the upper hinge bracket 534, and the top of the upper hinge bracket 534 is fixedly connected to the scraper 7;

[0054] In this way, the bottom articulated bracket 531 , the front articulated bracket 532 , the rear articulated bracket 533 and the upper articulated bracket 534 form a four-bar linkage mechanism to move, thereby changing the radial heights of the three scrapers 7 .

[0055] As an optional implementation, Figure 3 , 7 As shown, the scraper 7 is provided with scraping strips 71 inclined to the axis of the movable tube 33 at equal intervals, and the scraping strips 71 are divided into rust-removing scraping strips 711 with frosted material on the top and chip-removing steel brushes 712 with steel brushes on the top. The rust-removing scraping strips 711 and the chip-removing steel brushes 712 are arranged at intervals, and the height of the chip-removing steel brushes 712 is higher than the rust-removing scraping strips 711;

[0056] In this way, the chip removal steel brush 712 is higher than the rust removal scraper bar 711. The rigid rust removal scraper bar 711 can strongly clean the inner wall of the pipe when the scraper 7 rotates, and can also forcefully press against the inner wall of the pipe as a support point. The relatively flexible chip removal steel brush 712 can also clean the inner wall of the pipe. The two can flexibly change the distance between the scraper 7 and the inner wall of the pipe according to the actual pipe requirements, select the cleaning degree or support requirements, and the inclined scraper bar 71 can sweep out the scraper bar 71 while cleaning, and it will be sucked away by the suction hood 81 or the suction hood 35.

[0057] As an optional implementation, Figure 3 As shown, the telescopic transmission assembly 6 includes a first support ring plate 61 and a second support ring plate 62 which are symmetrically fixedly connected to the front and rear ends of the mounting sleeve 52, and three second telescopic cylinders 63 are fixedly connected to the second support ring plate 62 at the rear end in an equal circumference, and the three second telescopic cylinders 63 penetrate the first support ring plate 61, and the telescopic ends of the three second telescopic cylinders 63 are fixedly connected to a transmission plate 64, and the outer circular end of the transmission plate 64 is hinged with three pulling brackets 65 in an equal circumference, and the other ends of the three pulling brackets 65 are respectively hinged to the middle part of the corresponding front hinge bracket 532;

[0058] In this way, through the extension and retraction of the second telescopic cylinder 63 , the transmission plate 64 pulls or pushes the three pulling brackets 65 , thereby driving the three movable bracket groups 53 to expand or contract.

[0059] As an optional implementation, Figure 3 , 4 As shown, the auxiliary cleaning mechanism 8 includes a suction hood 81 fixedly connected to the suction port 34, the suction hood 81 is wide at the top and narrow at the bottom, the transmission disc 64 is symmetrically fixedly connected with two transmission optical axes 82 on one side facing the suction hood 81, the two transmission optical axes 82 pass through the first supporting ring plate 61, the second supporting ring plate 62 and the suction hood 81 in sequence, the tops of the two transmission optical axes 82 are fixedly connected with push plates 83, the tops of the push plates 83 are folded with closed edges 831, the two sides of the push plates 83 are in contact with the inner walls of the suction hood 81, the bottom of the push plates 83 is also fixedly connected with a scraper tube portion 832, the scraper tube portion 832 is in contact with the inner wall of the movable tube 33, and the scraper A flow port 833 is provided at the center of the tube portion 832. The transmission disk 64 is symmetrically connected to two rotating shafts 84 that rotate toward one side of the suction hood 81. The two rotating shafts 84 pass through the first supporting ring plate 61, the second supporting ring plate 62, the suction hood 81 and the push plate 83 in sequence. The tops of the two rotating shafts 84 are fixedly connected to a copper brush wheel 85. A groove 86 is spirally provided on each of the rotating shafts 84. A matching ring block 87 is fixedly connected to each of the first supporting ring plates 61. The matching ring block 87 is sleeved on the corresponding rotating shaft 84. A protruding ball 88 is fixedly connected to the matching ring block 87. The protruding ball 88 is slidably connected to the groove 86.

[0060] In this way, the suction hood 81 is used to enhance the strength and longitudinal distance of suction. Whenever the second telescopic cylinder 63 extends and contracts, the transmission optical axis 82 will move linearly through the transmission disk 64, so that the push plate 83 and the scraper tube portion 832 scrape the inner wall of the air outlet of the movable tube 33 and the inner wall of the suction hood 81. At the same time, as the rotating shaft 84 moves forward, the raised ball 88 on the ring block 87 limits the hook groove, so that the rotating shaft 84 and the copper brush wheel 85 rotate together, so that the copper brush wheel 85 sweeps away the accumulated debris.

[0061] As an optional embodiment, the movable tube 33 is internally plated with a copper layer, and the suction hood 81 is made of copper;

[0062] Copper is a material with high reflectivity and high thermal conductivity, which can reduce the damage of the laser penetrating through the pipeline to the movable tube 33 and the suction hood 81 .

[0063] As an optional embodiment, the spiral directions of the grooves 86 on the two rotating shafts 84 are opposite;

[0064] In this way, the two copper brush wheels 85 can sweep away the accumulated debris in pairs.

[0065] As an optional implementation, Figure 3 As shown, the end of the movable tube 33 is fixedly connected with a trumpet-shaped air suction cover 35;

[0066] This makes it easier for the movable tube 33 to inhale air.
