Description

[0002] Thick-walled pipes generally refer to pipes with large wall thickness, which are used in petroleum, chemical industry, urban construction, etc. Because of their large wall thickness, they have higher pressure and higher temperature than ordinary pipes. In order to enhance the connection strength and improve the welding quality of the pipe after welding, the end of the pipe needs to be beveled, thereby facilitating subsequent welding by welders or automatic welders. The existing thick-walled pipe groove cutting machines are mostly externally mounted pipe cutting groove cutting machines. The main structure is a circular support. After the support is sleeved on the outside of the pipe, the support is coaxial with the pipe using bolts and other devices. The groove cutting knife moves around the center of the support to cut the pipe.

[0003] In the prior art, the groove cutting knife moves around the pipe port during the groove cutting process, which is completely independent of the water cooling process.

When the beveling cooling water tank 101 is driven by the second hydraulic cylinder 110 to move upward to the set position, the output shaft stretching movement is controlled by the electric telescopic rod 406 to drive the screw adapter frame 408 to rotate forward, which synchronously drives the feeding drive disc 407 to rotate forward under the action of the screw adapter frame 408, so that the respective feeding control members 505 are gathered by sliding along the respective return knife grooves 413, until the respective feeding control members 505 are slid from the return knife grooves 413 into the first arc-shaped positioning grooves 411, at this time, the respective beveling knives 501 are close to the thick-walled pipe 3 port (at this time, the respective beveling knives 501 can also be pressed on the thick-walled pipe 3 port), then the beveling control motor 115 is controlled to rotate the entire beveling mechanism 2, so that the beveling knives 501 move in a ring around the thick-walled pipe 3 port to realize the opening of the port, in this process, the output shaft stretching movement is controlled by the electric telescopic rod 406 again, so that the feeding drive disc 407 is further slowly rotated forward, and the respective feeding control members 505 are slid from the first arc-shaped positioning grooves 411 into the first feeding grooves 414 and gradually slide, thereby realizing the further gathering of the respective beveling knives 501 arranged in a ring, and the automatic feeding of the respective beveling knives 501 in the beveling process is realized by this control mode, thereby ensuring the continuity of the thick-walled pipe 3 port processing and reducing the probability of invalid movement of the beveling knives 501 (i.e. reducing the probability of the beveling knives 501 not cutting the thick-walled pipe 3 during movement).

[0047] The movement amplitude of the respective feeding control members 505 in the first feeding grooves 414 can be controlled to realize the control of the beveling depth, and when the respective feeding control members 505 are slid from the first feeding grooves 414 into the second arc-shaped positioning grooves 412 and the continuous movement of the respective feeding control members 505 is stopped, the positions of the respective beveling knives 501 are fixed, at this time, the respective beveling knives 501 moving in a ring can realize the processing of burrs that may occur in the beveling position, and the design of the second feeding grooves 415 and the annular positioning grooves 410 can satisfy the beveling processing of the thick-walled pipe 3 with a relatively small diameter or the processing of a deep bevel.

[0049] The other side of the hollow flow guide part 506 is fixed with a second flow guide pipe 510 in communication with the inner cavity thereof, the first flow guide pipe 507 is slidingly fitted inside the corresponding radial guide port 405, the second flow guide pipe 510 is arranged in communication with the water suction cylinder 502, the water suction piston disc 504 is slidingly arranged inside the water suction cylinder 502, the surface of the water suction piston disc 504 is fixed with a force receiving moving rod 511 slidingly penetrating the water suction cylinder 502, the force receiving moving rod 511 is fixedly connected with the force receiving extrusion ball 503, the force receiving extrusion ball 503 is connected with the water suction cylinder 502 through the elastic element 512, a plurality of water suction pipes 513 are arranged in communication with the water suction cylinder 502 at a position close to the second flow guide pipe 510 on the peripheral side surface of the water suction cylinder 502, and a one-way valve 514 is installed on each water suction pipe 513; during the rotation of the beveling mechanism 2, when the force receiving extrusion ball 503 contacts the inclined guide plate 102, the force receiving extrusion ball 503 slides downward along the inclined guide plate 102, the force receiving extrusion ball 503 gradually moves close to the water suction cylinder 502 and compresses the elastic element 512, under the action of the force receiving moving rod 511, the water suction piston disc 504 is pushed to slide along the inner wall of the water suction cylinder 502 and move close to the hollow flow guide part 506, the air in the hollow flow guide part 506 is exhausted through the water suction piston disc 504, and after the force receiving extrusion ball 503 is separated from the inclined guide plate 102, the force receiving extrusion ball 503 moves downward under the action of its own gravity (at this time, the entire water suction cylinder 502 is below the water surface), the water suction piston disc 504 moves downward under the joint action of the elastic element 512 and the force receiving extrusion ball 503, thereby rapidly sucking the water in the beveling water tank 101 into the water suction cylinder 502, so that the water suction cylinder 502 completes the water taking action, when the water suction cylinder 502 that has completed the water taking moves to the upper position (specifically, above the horizontal position), the water in the water suction cylinder 502 flows to the beveling cutter 501 along the flow guide water channel and flows out to the beveling position, so that the water spraying and cooling treatment of the beveling cutter 501 and the port position of the thick-walled pipeline 3 is simultaneously realized, at the same time, since the force receiving extrusion ball 503 is above the horizontal position, the force receiving extrusion ball 503 drives the water suction piston disc 504 to move close to the beveling cutter 501 under its own weight, so that the water in the water suction cylinder 502 is pressurized to accelerate the water injection to the beveling cutter 501 and the thick-walled pipeline 3, during the movement of the beveling cutter 501, the water in the water suction cylinder 502 can continuously flow out to cool, thereby improving the cooling effect of the beveling cutter 501 and the thick-walled pipeline 3, and when the force receiving extrusion ball 503 rotates below the horizontal position again, the water suction piston disc 504 moves downward to complete the reset under the joint action of the elastic element 512 and the force receiving extrusion ball 503, that is, the water suction piston disc 504 is repositioned against the inner end of the water suction cylinder 502 close to the elastic element 512.
