Description

Technical Field

[0001] The present application relates to the technical field of steel pipe deburring, and in particular to a deburring mechanism for steel pipe production. Background Art

[0002] Steel pipe is a hollow long steel strip, which is mainly used for conveying fluids, manufacturing mechanical parts and engineering structures; steel pipe has a hollow cross-section, is light in weight, and is also an economical pipe. Steel pipes can usually be divided into two categories according to the production method: seamless steel pipes and seamed steel pipes. Among them, seamed steel pipes are welded steel pipes, which are steel pipes with seams on the surface that are formed by bending steel strips or steel plates into round, square and other shapes and then welding them.

[0003] Burrs are thorn-like objects or flash formed by processing the intersection of parts and surfaces. After the seam steel pipe is formed, there will be burrs at the welds of the inner and outer walls of the steel pipe. In order to ensure the service life of the steel pipe, these burrs need to be removed. Usually, workers will use scrapers to scrape off the burrs on the inner and outer walls of the steel pipe.

[0004] When scraping burrs on the inner wall of a steel pipe, a worker needs to extend the scraper to the starting position of scraping burrs inside the steel pipe, and then apply force to the scraper along the weld to move the scraper to scrape off the burrs. However, when the length of the steel pipe is long, it is inconvenient for the worker to send the scraper to the burr scraping position and apply force and move it, so it is not easy for the worker to scrape burrs.

[0050] Reference Figure 2 and Figure 3 The multi-stage tube body 24 includes a tube body 241, which is inserted into the base tube 31 and is slidably connected to the inner wall of the base tube 31, and the outer wall of the tube body 241 is in contact with the inner wall of the base tube 31; the inner wall of the tube body 241 is also slidably connected to the tube body 242, and the outer wall of the tube body 242 is in contact with the inner wall of the tube body 241, and the burr scraping member 4 is arranged on the tube body 242; the feeding mechanism 25 is connected to both the tube body 1 241 and the tube body 2 242, and the feeding mechanism 25 can drive the tube body 1 241 and the tube body 2 242 to move.

[0051] The driving mechanism 25 can drive the first tube body 241 to move laterally relative to the base tube 31 and simultaneously drive the second tube body 242 to move laterally relative to the first tube body 241 .

[0052] Reference Figure 3 and Figure 4 In order to ensure that there is more space inside the base tube 31 for installing other structures, the first tube body 241 includes a main tube portion 2411 and a residual tube portion 2412. The residual tube portion 2412 is connected to the left end of the main tube portion 2411. The main tube portion 2411 and the residual tube portion 2412 are an integral piece. Both the residual tube portion 2412 and the main tube portion 2411 can slide along the inner wall of the base tube 31. In addition, since the structure of the second tube body 242 is the same as that of the first tube body 241, it will not be repeated here.

[0053] Reference Figure 5 and Figure 6The feeding mechanism 25 includes a mounting seat 251, which is connected to the left end of the tube body 1 241. The mounting seat 251 is provided with a feeding member 252 and a transmission assembly 253. The transmission assembly 253 is connected to the feeding member 252. The feeding member 252 is preferably a small motor. The mounting seat 251 is rotatably connected to a transmission shaft 1 254. The transmission shaft 1 254 is provided with a linkage gear 255 that can rotate synchronously with the transmission shaft 1 254. The linkage gear 255 is connected to the transmission assembly 253. A receiving groove 311 is provided on the inner wall of the base tube 31 on one side of the linkage gear 255. A rack 256 is fixedly connected to the receiving groove 311 on the base tube 31.

The rack 257 is arranged horizontally. The rack 256 and the rack 257 are respectively located on both sides of the linkage gear 255. In order to ensure the movement stability of the tube body 1 241 and the tube body 2 242, the first and second racks 256 and 257 are respectively arranged on the second and second sides of the linkage gear 255. Figure 3 The feeding mechanism 25 is provided with two groups, and the two groups of feeding mechanisms 25 are arranged up and down for this.

[0054] The driving member 252 drives the linkage gear 255 to rotate counterclockwise through the transmission assembly 253. At this time, under the meshing action of the linkage gear 255, the rack 1 256 and the rack 2 257, the tube body 1 241 will move rightward relative to the base tube 31, and the tube body 2 242 will also move rightward relative to the tube body 1 241. On the contrary, if the linkage gear 255 rotates clockwise, the tube body 1 241 will move leftward relative to the base tube 31, and the tube body 2 242 will also move leftward relative to the tube body 1 241.

[0055] Reference Figure 6 The transmission assembly 253 includes a worm 2531 disposed on the mounting seat 251, the worm 2531 is rotatably connected to the mounting seat 251, the feed member 252 is connected to the worm 2531, the worm 2531 is vertically arranged, the mounting seat 251 is also rotatably connected to the second transmission shaft 2532, the second transmission shaft 2532 is provided with a worm wheel 2533 that can rotate synchronously, the worm 2531 and the worm wheel 2533 are meshed, and the worm wheel 2533 and the worm 2531 can be self-locking.

[0056] The driving member 252 drives the worm 2531 to rotate, thereby driving the worm wheel 2533 to rotate. The rotation of the worm wheel 2533 drives the transmission gear 2534 to rotate through the transmission shaft 2532. The rotation of the transmission gear 2534 drives the linkage gear 255 to rotate.

[0057] The self-locking characteristics of the worm 2531 and the worm wheel 2533 can be used to prevent the burr scraper 4 from being subjected to force, which may cause the second tube body 242 and the first tube body 241 to malfunction, and may cause the output end of the actuator 252 to malfunction.

[0058] Reference Figure 3 The second tube body 242 includes a vertical tube portion 2421 and a horizontal tube portion 2422.

A seat 42 is mounted on the upper end of the connecting rod 41, and a scraper 43 is mounted on the seat 42. The scraper 43 is a triangular scraper in this embodiment. Different types of burrs require different types of scrapers 43 for scraping. In order to broaden the application scope of this application, the seat 42 and the connecting rod 41 are connected by screws, and the seat 42 and the scraper 43 can be disassembled for replacement.

[0062] Reference Figure 8 Combined with Figure 3 The suction device 5 includes a connecting seat 51 installed at the left end of the base tube 31, and a suction assembly 52 is installed on the connecting seat 51.

[0063] Reference Figure 8 Combined with Figure 3Specifically, the suction assembly 52 includes a collecting cylinder 521 installed on the connecting seat 51, the collecting cylinder 521 is provided with a suction hole 5211 and a feeding hole 5212 relative to each other, the suction hole 5211 is located on the left side of the feeding hole 5212, the connecting seat 51 is provided with a suction piece 54, the suction piece 54 is a suction motor, the suction piece 54 is connected with the suction hole 5211, and the suction piece 54 can generate negative pressure in the collecting cylinder 521 through the suction hole 5211; a connecting hole 312 is provided on the base tube 31, and the feeding hole 5212 is connected with the telescopic tube 53 through the connecting hole 312.

[0064] The suction piece 54 can be used to generate negative pressure in the collecting tube 521 , and the burrs that fall into the vertical tube portion 2421 will enter the collecting tube 521 through the horizontal tube portion 2422 and the telescopic tube 53 and be collected.

[0065] Reference Figure 8 In order to facilitate the cleaning of burrs in the collecting tube 521, an installation space 511 is formed on the connecting seat 51, and the collecting tube 521 is located in the installation space 511; a receiving groove 512 is opened on the wall surface of the connecting seat 51 and is located on the left side of the collecting tube 521.

The filter 55 can block the burrs. In this embodiment, the filter 55 is preferably Hepa filter paper.

[0068] In the present application, the actuator 252 outputs a relatively low rotation speed to enable the tube body 1 241 and the tube body 2 242 to move quickly and synchronously. Based on this, the scraper 43 will also move relatively quickly along the weld. The scraper 43 can effectively remove burrs on the inner wall of the steel pipe with high efficiency; and because the telescopic device 3 is tubular in shape, the scraper 43 can be sent to a deeper part of the steel pipe for burr removal.

[0070] First, the horizontal reciprocating cylinder 21 and the vertical reciprocating cylinder 23 are used to drive the scraper 43 to the starting position for scraping burrs, and then the feeding member 252 is driven to drive the worm 2531 to rotate, thereby driving the worm wheel 2533 to rotate. The rotation of the worm wheel 2533 will drive the transmission gear 2534 to rotate through the transmission shaft 2532, and the rotation of the transmission gear 2534 will drive the linkage gear 255 to rotate. At this time, the linkage gear 255 is meshed with the rack 1 256 and the rack 2 257. Under the cooperative effect, the tube body 1 241 will move left and right relative to the base tube 31, and the tube body 2 242 will also move left and right relative to the tube body 1 241. The scraper 43 will move left and right along with the tube body 1 241 to scrape the burrs on the weld into the vertical tube part 2421. In addition, the suction piece 54 will generate negative pressure in the collecting tube 521, and the burrs that fall into the vertical tube part 2421 will enter the collecting tube 521 through the horizontal tube part 2422 and the telescopic tube 53 and be collected.

[0071] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
