Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a steel pipe end face chamfering and deburring equipment. Background Technology

[0002] Steel pipe is a long strip of steel with a hollow cross-section. Based on the rolling process, it can be divided into hot-rolled steel pipe and cold-rolled steel pipe; based on whether it has a seam, it can be divided into seamless steel pipe and welded steel pipe. Seamless steel pipe is produced through processes such as piercing and rolling, and is suitable for high-pressure and high-temperature conditions; welded steel pipe is formed by rolling and welding steel plates, and features high production efficiency and diverse specifications.

[0003] Chamfering of steel pipes is a process of cutting the ends or edges of pipes to create a beveled surface at a specific angle. Existing steel pipe end-face processing equipment separates the chamfering and deburring processes. After chamfering, the pipes must be manually transferred to grinding equipment or manually ground. This is not only inefficient but also prone to poor end-face flatness and incomplete burr removal due to manual operation, affecting product consistency. To address this technical problem, this application proposes a steel pipe end-face chamfering and deburring device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a steel pipe end face chamfering and deburring device, including a lathe 1, a guide rail 2 fixedly connected to the top of the lathe 1, two parallel positioning rods 3 fixedly connected to the top of the lathe 1 along the length direction, heat dissipation plates 4 installed on both sides of the lathe 1, two symmetrically distributed support frames 5 connected to the guide rail 2 through a drive component, positioning blocks 6 fixedly connected to both sides of the support frames 5, the inner wall of the positioning blocks 6 being slidably connected to the positioning rods 3, the bottom side of the support frames 5 being slidably connected to the guide rail 2 through a slider, a drive box 9 fixedly installed on the opposite side of the support frames 5, a cutter head 8 installed on the adjacent side of the support frames 5, grinding components and chamfering components being distributed circumferentially on the outer wall of the cutter head 8, a fixing plate 10 welded and fixed in the middle of the guide rail 2, a limit clamp 11 installed on the top of the fixing plate 10, ejection blocks 24 provided on both sides of the limit clamp 11, and a feed plate 12 fixedly connected to the rear side of the fixing plate 10.

[0019] Specifically, the positions of the support frame 5 and the grinding and chamfering components on the cutter head 8 are adjusted according to the required chamfering position of the steel pipe. Then, the steel pipe is placed into the feed plate 12. The feed plate 12 automatically slides the steel pipe onto the fixing plate 10 through the inclined design. The fixing plate 10 has a groove, and the steel pipe will roll into the groove. Then, the limiting clamp 11 will limit the steel pipe. The bottom of the limiting clamp 11 is equipped with a cylinder drive linkage. The cylinder drive linkage drives the two limiting clamps 11 to clamp the steel pipe, thereby limiting the steel pipe. Then, the drive component drives the cutter head 8 on the support frame 5 to approach the steel pipe. Then, the motor in the drive box 9 will drive the cutter head 8 to rotate, chamfering and grinding the steel pipe. After grinding, the ejector block 24 will push the steel pipe out of the groove. Then, the steel pipe will slide out from the inclined plate on the other side, completing the discharge.

[0020] Reference Figures 3-5The driving components include a motor 13 and a threaded rod 14. One end of the threaded rod 14 is fixedly connected to the driving end of the motor 13 via a coupling, and the other end of the threaded rod 14 is rotatably connected to the lathe 1 via a fixed sleeve. The threaded rod 14 adopts a ball screw structure and is parallel to the guide rail 2 to ensure smooth feeding of the support frame 5. A connecting block 7 is welded and fixed to the bottom side of the support frame 5. The connecting block 7 has an internal thread that is compatible with the threaded rod 14 and is threadedly connected to it. The motor 13 drives the threaded rod 14 to rotate, and the rotation of the threaded rod 14 drives the two connecting blocks 7 to move, thereby realizing the movement of the support frame 5.

[0021] The chamfering assembly includes a fixing base 15, a clamping plate 16, a fixing bolt 17, and a blade 18. The clamping plate 16 is assembled to the outer wall of the fixing base 15 by the fixing bolt 17. The clamping plate 16 and the fixing base 15 clamp the blade 18 and fix it by limiting its position with the fixing bolt 17. According to the diameter of the steel pipe, the blade 18 is placed at a suitable adjustment hole 20. The fixing bolt 17 is passed through the adjustment hole 20 and the clamping plate 16 is installed. After adjusting the position of the blade 18, the fixing bolt 17 is tightened to fix it.

[0022] The grinding assembly includes a second mounting base 19, a pressing plate 23, grinding plates 21, and a spring 22. The pressing plate 23 is installed on the inner wall of the second mounting base 19 by fixing bolts 17. Two grinding plates 21 are slidably connected to the inner wall of the pressing plate 23. A spring 22 is provided on the opposite side of the two grinding plates 21. The first mounting base 15, the clamping plate 16, and the second mounting base 19 are all provided with multiple adjustment holes 20. The first mounting base 15 and the second mounting base 19 are both welded to the outer wall of the cutter head 8. According to the diameter of the steel pipe, the pressing plate 23 is installed in the appropriate adjustment hole 20 and the bolts are tightened to fix it. The inner wall of the pressing plate 23 has a matching nut to facilitate the fixing bolts 17 to fix it. The front end of the grinding plate 21 is designed to be inclined so that the steel pipe can be inserted into the inner wall of the two grinding plates 21. Then, the spring 22 will fix the grinding plate 21 to the steel pipe by its own elasticity.

[0023] Working principle: Based on the required chamfering position of the steel pipe, the blade 18 is moved in advance to the corresponding adjustment hole 20 of the fixed seat 15 and fixed with the fixing bolt 17. When chamfering the outer corner, the blade 18 needs to be fixed in the adjustment hole 20 on the outer periphery of the cutter head 8. When chamfering the inner corner, the blade 18 needs to be installed in the adjustment hole 20 near the inner periphery of the cutter head 8, so that the blade 18 is attached to the outer or inner wall of the steel pipe during chamfering. The clamping plate 16 will clamp the blade 18 by tightening the fixing bolt 17 to prevent movement. Similarly, the pressing plate 23 is moved to the position of the corresponding adjustment hole 20 in the fixed seat 29. The pressing plate 23 is provided with a nut. The fixing bolt 17 is inserted into the adjustment hole 20 and the nut and tightened to fix the pressing plate 23. Then, the steel pipe can be fed into the feeding plate 12 one by one through common conveying components such as conveyor belts. The feeding plate 12 automatically feeds the steel pipe through the 10°-15° slope design. The steel pipe slides into the groove of the fixed plate 10 without being ejected due to excessive speed impacting the groove. As the steel pipe rolls into the groove, the limiting clamp 11 clamps and limits the steel pipe. The motor 13 drives the threaded rod 14 to rotate, and the rotation of the threaded rod 14 drives the two connecting blocks 7 to move, thereby realizing the movement of the support frame 5. The support frame 5 moves on the guide rail 2 via the slider on the bottom side, clamping the steel pipe and bringing the cutter head 8 closer to the steel pipe. The slope at the front end of the grinding plate 21 causes the steel pipe to be inserted between the two grinding plates 21, and the spring 22 clamps the steel pipe with the grinding plates 21. Then, the motor in the drive box 9 drives the cutter head 8 to rotate, the blade 18 chamfers the steel pipe, and the grinding plate 21 grinds to prevent burrs from appearing on the steel pipe. After the chamfering is completed, the limiting clamp 11 releases the clamp, and the internal cylinder drives the ejector block 24 to lift and push the steel pipe out of the groove. The steel pipe slides out from the slope on the other side, completing the discharge.

[0024] It is worth noting that the circuits, motors, and cylinders involved in the above embodiments all adopt corresponding existing technologies according to the actual situation, so they will not be described in detail in the embodiments of this application.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
