Description

Technical Field

[0001] This invention relates to the field of welded pipe processing technology, and in particular to a welded pipe end face processing equipment. Background Technology

[0002] Welded pipe, as an important metal pressure processing product, is a hollow steel material made from steel plates or strips through a precise rolling process and then welded using advanced welding technology. Due to its unique structural characteristics, welded pipe has been widely used in numerous fields. Whether it's in fluid transportation for conveying various liquids and gases, ensuring the stable transmission of energy and resources; in building structures as a key supporting component, providing a solid guarantee for the stability of buildings; or in industrial equipment as a component of various devices, contributing to the efficient operation of industrial production, welded pipe plays an indispensable role. In the production process of welded pipe… In order to prevent welding defects, improve weld integrity, and ensure that the quality and performance of welded pipes meet the requirements of use, a series of treatments are usually required on the end face of the welded pipe. Common treatment methods include milling and chamfering. Milling can make the end face of the welded pipe smooth and flat by cutting with precise tools, removing impurities such as burrs and oxide scale, improving the accuracy and quality of the end face, and providing a good foundation for subsequent welding, connection and other processes. Existing welded pipe end face treatment equipment can usually only perform chamfering or milling. Therefore, when another process is needed after completing the chamfering or milling process, the equipment needs to be replaced, which is inconvenient and costly. Summary of the Invention

An outer tube sleeve 8 is provided on the side of the tool holder 3 away from the clamping member 1. The outer tube sleeve 8 is fixedly connected to the fixed tool holder 4. An inner tube sleeve 10 is provided inside the outer tube sleeve 8 and driven by a hydraulic rod 9. The inner tube sleeve 10 is fixedly connected to the movable tool holder 5. When chamfering is required, the hydraulic rod 9 drives the inner tube sleeve 10 to move the movable tool holder 5 and the chamfering tool 6 forward to chamfer the end of the welding pipe. When a flat end is required, the hydraulic rod 9 drives the movable tool holder 5 to retract, and the flat tool 7 is exposed.

[0017] Both the fixed tool holder 4 and the movable tool holder 5 are provided with tool grooves 11, and a row of fixing holes 21 are provided in the tool grooves 11. The chamfering tool 6 and the flat tool 7 are fixed in the tool grooves 11 by bolts to the fixing holes.

[0018] All the cutting grooves 11 are inclined grooves, and the chamfering knife 6 and the flat knife 7 cut the welded pipe at an angle when working.

[0019] An inner baffle 20 driven by a hydraulic rod 9 is provided inside the inner tube sleeve 10. An outer baffle 12 is fitted on the outer side of the inner tube sleeve 10 and on the movable end of the hydraulic rod 9. The outer baffle 12 is fixedly connected to the movable end of the hydraulic rod 9. Four connecting pieces 13 are evenly distributed on the outer edge of the outer baffle 12. One end of the connecting piece 13 is rotatably connected to the outer baffle 12, and the other end of the connecting piece 13 is provided with a limit rod 14. The middle section of the limit rod 14 is rotatably connected to the connecting piece 13. The end of the limit rod 14 near the outer tube sleeve 8 is rotatably connected to the rotating seat 24. The rotating seat 24 is fixedly connected to the outer tube sleeve 8. A limit block 15 is fixedly connected to the end of the limit rod 14 away from the outer tube sleeve 8. Four evenly distributed movable slots 23 are fixedly connected to the outer tube sleeve 8. Movable blocks 22 extending out of the movable slots 23 are fixedly connected to the inner tube sleeve 10. The movable blocks 22 and the limit blocks 15 are used in conjunction. The movable blocks 22, movable slots 23, limit rods 14 and connecting pieces 13 are located on the same straight line.

[0020] A conformal groove is provided at the contact point between the movable block 22 and the limiting block 15.

[0021] The tool holder 3 is circular. There are four fixed tool holders 4 and four movable tool holders 5. The fixed tool holders 4 and the movable tool holders 5 are fan-shaped tool holders with the same shape. A guide block 16 is provided on one side of the fixed tool holder, and a guide groove 17 that cooperates with the guide block 16 is provided on the other side.

[0022] The clamping member 1 includes a base 18 and an upper pressure block 19 driven by a cylinder.

[0023] Working principle: The welded pipe requiring end-face treatment is placed on the placement base 18. The upper pressure block 19 presses down to clamp the welded pipe. When chamfering is required on the end face of the welded pipe, the hydraulic rod 9 drives the outer baffle 12 to move forward until the outer baffle 12 is in contact with the outer wall of the inner sleeve 10, and drives the inner sleeve 10 to move forward, causing the movable block 22 to move to the front end of the movable groove 23. The limiting rod 14 and the limiting block 15 are pressed against the conformal groove of the movable block 22 by the connecting piece 13, and the chamfer is achieved. As the inner sleeve 10 moves forward, the blade 6 extends beyond the flat blade 7. The external drive mechanism drives the blade holder 3 to rotate. When milling of the welded pipe is required, the hydraulic rod 9 drives the inner baffle 20 to move outward until the inner baffle 20 is in contact with the inner wall of the inner sleeve 10. At this time, the limiting rod 14 and the limiting block 15 are initially opened under the action of the connecting piece 13. The hydraulic rod 9 continues to drive the inner baffle 20 to move outward and pulls the inner sleeve 10, the movable block 22 and the chamfering blade 6 back, exposing the flat blade 7.

[0024] This ingenious design utilizes a hydraulic rod to drive a movable tool holder, which in turn moves the chamfering tool back and forth. This allows for chamfering or milling of the welded pipe end face using a single device, eliminating the need to change equipment and effectively reducing equipment and time costs. During use, a limit block clamps the movable block to prevent the chamfering tool from shifting position during cutting, improving machining accuracy. The tool groove is angled, effectively enhancing the surface finish. The tool is secured with fixing holes and bolts, facilitating tool replacement.

[0025] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
