Description

Technical Field

[0001] This utility model relates to the field of double-head chamfering technology for pipes, specifically a double-head chamfering machine for pipes. Background Technology

[0002] The double-head pipe chamfering machine is an automated device specifically designed for chamfering both ends of pipes. Using two symmetrically arranged sets of cutters or processing mechanisms, it can simultaneously cut both ends of the pipe, removing burrs and sharp angles to create smooth bevels or rounded corners. Widely used in the processing of metal pipes (such as steel and copper pipes), it improves the sealing and safety of pipe connections while enhancing the efficiency and quality of subsequent welding and assembly processes. It features convenient operation, high processing precision, and strong batch processing capabilities.

[0003] However, existing double-headed pipe chamfering machines often have the problem of limited functionality in actual use. Most machines can only perform internal or external chamfering operations. If different pipes are chamfered in sequence, two chamfering processes may need to be completed. This requires changing different processing components or disassembling and replacing the chamfering parts, which is not only cumbersome and time-consuming, but also affects processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a double-headed chamfering machine for pipes, in order to solve the problem that most devices mentioned in the background art can only perform internal or external chamfering operations alone.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A double-head chamfering machine for pipes includes a mounting frame and two sliding seats. A rotating frame is rotatably mounted inside the sliding seats, and a chamfering assembly is disposed inside the rotating frame.

[0007] The chamfering assembly includes a rotating groove, inside which a rotating plate is rotatably mounted, and on both sides of the rotating plate are an inner chamfering component and an outer chamfering component, respectively.

[0008] In a preferred embodiment of this utility model, the mounting bracket is provided with slide rails on both sides, and two sliding seats are slidably installed in the slide rails on both sides. An electric telescopic rod is provided on the outside of the slide rails, and the telescopic end of the electric telescopic rod is connected to the sliding seat.

[0009] In a preferred embodiment of this utility model, a motor is provided on the outside of the sliding seat, and the output end of the motor is connected to the rotating frame.

[0010] In a preferred embodiment of the present invention, a sliding groove is provided at the top of the rotating groove, and a sliding block is slidably disposed inside the sliding groove.

[0011] In a preferred embodiment of the present invention, a rectangular block is provided at the bottom of the sliding block, and a rectangular groove is provided at the top inner side of the rotating plate, and the rectangular block is assembled and disassembled in the rectangular groove.

[0012] In a preferred embodiment of this utility model, a threaded opening is provided at the top of the sliding groove, and a bolt is provided inside the threaded opening. The bolt is threadedly connected to the threaded opening, and the bottom of the bolt is rotatably connected to the sliding block.

[0013] In a preferred embodiment of this utility model, a limiting groove is provided on the top of the rotating frame, a spring is provided inside the limiting groove, and a sliding rod is provided on the spring, the sliding rod being slidably connected to the limiting groove.

[0014] In a preferred embodiment of this utility model, a limiting port is provided on one side of the top of the bolt, and the sliding rod is installed and removed in the limiting port.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: By rotating the rotating plate, the inner or outer chamfering piece can be moved out of the rotating frame, allowing for inner or outer chamfering of the pipe. After the rotating plate has rotated, the inner or outer chamfering piece is located outside the rotating frame, and the rectangular blocks are aligned with the rectangular slots. By rotating the bolts at the top, the sliding block slides, and the rectangular block inserts into the rectangular slot, thus fixing the position of the rotating plate and the chamfering piece. The rotating frame is driven by a motor to rotate, thereby rotating the chamfering piece and chamfering the pipe. The modular design of the rotating plate and the chamfering piece makes the switching between inner and outer chamfering functions more convenient and efficient, reduces process changeover time, and further optimizes the pipe chamfering process.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model discloses a double-headed chamfering machine for pipes, including a mounting frame 1 and two sliding seats 12. The mounting frame 1 is a mounting structure used to install other structures. The two sliding seats 12 are also mounting structures. Slide rails 11 are provided on both sides of the mounting frame 1. The two sliding seats 12 are slidably installed in the slide rails 11 on both sides. An electric telescopic rod 13 is provided on the outside of the slide rails 11. The electric telescopic rod 13 is a servo electric telescopic rod. The telescopic end of the electric telescopic rod 13 is connected to the sliding seat 12. That is, the electric telescopic rod 13 drives the sliding seat 12 and the chamfering structure to extend and retract, thereby chamfering and grinding the pipe. During grinding, the initial extension distance of the electric telescopic rod 13 and the extension distance during grinding are pre-adjusted according to the length of the pipe. All electrical structures in the structure are controlled by the same external computer PLC controller, which is a conventional technical means for those skilled in the art.

[0026] In practical applications, this equipment can be used in conjunction with existing pipe feeding structures (such as conveyor rollers, robotic arm feeding mechanisms, etc.). When using conveyor rollers for feeding, a limiting block adapted to the rollers can be set in the middle of the mounting frame 1 to ensure that the pipe remains axially stable during the chamfering process. If using robotic arm feeding, after the robotic arm positions and clamps the pipe, the equipment's PLC controller can receive the feeding completion signal and automatically start the motor 14 and the electric telescopic rod 13 to perform the chamfering operation. After the chamfering is completed, the sliding seat 12 resets, and the feeding structure removes the processed pipe, realizing continuous production.

[0027] A rotating frame 2 is rotatably mounted inside the sliding seat 12. A chamfering assembly is installed inside the rotating frame 2. The chamfering assembly includes a rotating groove 21. A rotating plate 22 is rotatably mounted inside the rotating groove 21. An inner chamfering piece 23 and an outer chamfering piece 24 are respectively mounted on both sides of the rotating plate 22. The inner chamfering piece 23 is concave at 45°, and the outer chamfering piece 24 is convex at 45°. That is, by rotating the rotating plate 22, the inner chamfering piece 23 or the outer chamfering piece 24 can be moved out of the rotating frame 2, so that the pipe can be chamfered or chamfered. A motor 14 is installed on the outside of the sliding seat 12. The output end of the motor 14 is connected to the rotating frame 2. That is, by the motor 14 driving the rotating frame 2 to rotate, the chamfering piece can be rotated, so that the pipe can be chamfered and ground.

[0028] The top of the rotating groove 21 is provided with a sliding groove 3, and a sliding block 32 is slidably arranged inside the sliding groove 3. A rectangular block 34 is provided at the bottom of the sliding block 32. A rectangular groove 4 is provided on the top of the inner side of the rotating plate 22. The rectangular block 34 is installed and removed in the rectangular groove 4. Both the rectangular groove 4 and the rectangular block 34 are cubes. When the inner chamfer 23 or the outer chamfer 24 is outside the rotating frame 2, the rectangular block 34 is connected to the rectangular groove 4. The top of the sliding groove 3 is provided with a screw 31, and a bolt 33 is provided inside the screw 31. The bolt 33 is threadedly connected to the screw 31. The bottom of the bolt 33 is rotatably connected to the sliding block 32. When the rotating plate 22 is rotated, the inner chamfer 23 or the outer chamfer 24 is outside the rotating frame 2. That is, by rotating the bolt 33 at the top, the sliding block 32 is slidable, and the rectangular block 34 is inserted into the rectangular groove 4, thereby fixing the position of the rotating plate 22 and the chamfer.

[0029] The top of the rotating frame 2 is provided with a limiting groove 42, and a spring 43 is provided inside the limiting groove 42. A sliding rod 44 is provided on the spring 43. The sliding rod 44 is slidably connected to the limiting groove 42. A limiting port 41 is provided on one side of the top of the bolt 33. The sliding rod 44 is installed and removed in the limiting port 41. When the bolt 33 is tightened, the limiting port 41 aligns with the sliding rod 44. The spring 43 pushes the sliding rod 44 to insert it into the limiting port 41, thereby limiting the bolt 33 and preventing it from rotating, thus strengthening the fixation of the rotating plate 22.

[0030] The working principle of this utility model is as follows: the electric telescopic rod 13 drives the sliding seat 12 and the chamfering structure to extend and retract, thereby chamfering and grinding the pipe. The rotating plate 22 rotates, causing the inner chamfering piece 23 or the outer chamfering piece 24 to move out of the rotating frame 2, thus performing inner or outer chamfering on the pipe. After the rotating plate 22 has rotated, the inner chamfering piece 23 or the outer chamfering piece 24 is located outside the rotating frame 2, and the rectangular blocks 34 are all connected to the rectangular grooves 4. By rotating the bolt 33 at the top, the sliding block 32 slides, and the rectangular block 34 is inserted into the rectangular grooves 4, thereby fixing the position of the rotating plate 22 and the chamfering piece. The motor 14 drives the rotating frame 2 to rotate, thereby rotating the chamfering piece, thus performing chamfering and grinding on the pipe.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
