Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to an integrated device for bending and cutting pipes. Background Technology

[0002] Pipe bending machines are important equipment in the pipe fittings processing field. Their main function is to bend straight pipes to create pipe fittings of various shapes. In piping systems, elbows are an essential component, used to change the direction of fluid by 90-degree or 45-degree turns. Pipe bending machines process straight pipes into the required elbow shapes through a series of process steps. In the traditional pipe bending process, a straight pipe usually needs to be bent multiple times to achieve the final shape. Especially when making elbows, due to the small bending intervals, frequent bending operations are required. This processing method has some problems: First, each bend will cause a certain amount of deformation to the pipe fitting. This deformation will accumulate and affect the subsequent bending accuracy. Second, the complex shape of the bent pipe fitting will cause inconvenience to the subsequent cutting work, increasing the processing difficulty and time cost. Utility Model Content

[0015] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0016] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0017] according to Figures 1-4As shown, an integrated pipe bending and cutting device includes a worktable 1, on which a pair of moving platforms 2 are mounted. A feeding device 3 and a cutting device 4 are respectively mounted on the moving platforms 2. A pipe bending device 5 is also mounted at the end of the worktable 1, with the cutting device 4 positioned between the feeding device 3 and the pipe bending device 5. The pipe bending device 5 includes a drive device 51, on which a rotating table 52 is connected. The rotating table 52 is located on one side of the worktable 1, and a pipe bending mold 53 and a clamping mold 54 are mounted on the rotating table 52. Both the pipe bending mold 53 and the clamping mold 54 have semi-circular grooves that cooperate to form a through hole for clamping the pipe. The pipe bending mold 53 is positioned at the axis of rotation of the rotating table 52, and the clamping mold 54 is positioned on one side. When the pipe is clamped, the rotating table 52 is rotated by the drive device 51, allowing the pipe to be bent. The clamping mold 54 rotates around the bending mold 53, thereby bending the pipe fitting. The cutting device 4 includes a frame 41, with a mounting plate 42 on the top of the frame 41. A lifting cylinder 43 is mounted on the mounting plate 42. Lifting guide rails 44 are mounted on the front ends of both sides of the frame 41. Lifting plates 45 are mounted on the lifting guide rails 44. A cutting machine 46 is mounted on the lifting plates 45. The movable end of the lifting cylinder 43 is connected to the top of the cutting machine 46. The lifting plate 45 can be moved along the lifting guide rails 44 by the lifting cylinder 43, thereby moving the cutting machine 46 up and down to cut the pipe fitting. Fixed cylinders 47 are mounted on both sides of the frame 41. Fixed blocks 48 are connected to the movable ends of the fixed cylinders 47. The fixed blocks 48 are located inside the frame 41. The fixed blocks 48 can be fixed by controlling the movement of the fixed blocks 48 by the fixed cylinders 47, so that the fixed blocks 48 can fix the pipe fitting during bending or cutting.

[0018] The mobile platform 2 is mounted on the workbench 1 via a mobile guide rail 21. A drive motor 22 is mounted on the mobile platform 2, and a drive gear 23 is mounted on the movable end of the drive motor 22 passing through the mobile platform 2. A rack 24 that meshes with the drive gear 23 is mounted on one side of the workbench 1. The drive motor 22 controls the rotation of the drive gear 23, and the drive gear 23 and rack 24 enable the mobile platform 2 to move along the mobile guide rail 21, thereby allowing the feeding device 3 to feed materials and controlling the position of the cutting machine 46.

[0019] The clamping mold 54 is mounted on the rotary table 52 via a movable plate 55. A push cylinder 56 is provided at the bottom of the movable plate 55. The push cylinder 56 is rotatably mounted inside the rotary table 52. The movable end of the push cylinder 56 is hinged to the bottom of the movable plate 55. The push cylinder 56 can push the movable plate 55 to move, thereby allowing the clamping mold 54 to cooperate with the pipe bending mold 53 to clamp the pipe.

[0020] The fixing block 48 is provided with a fixing module 49, and the fixing module 49 is provided with a semi-circular groove. The two semi-circular grooves on both sides can be combined to form a round hole for fixing the pipe. The fixing module 49 is fixed on the fixing block 48 by bolts and can be replaced.

[0021] In practical application, one end of the pipe fitting is fixed to the feeding device 3, while the other end passes through the cutting device 4 and is positioned at the bending device 5. During operation, the clamping mold 54 and the bending mold 53 work together to clamp the pipe fitting. At the same time, the cutting device 4 moves to a predetermined position and, through the action of the fixing cylinder 47, pushes the fixing block 48 to fix the pipe fitting. Subsequently, the drive device 51 controls the rotary table 52 to rotate, realizing the bending operation of the pipe fitting. After bending, the lifting cylinder 43 controls the cutting machine 46 to descend vertically and precisely cut the pipe fitting. Then, the clamping mold 54 returns to its original position, and the bent and cut pipe fitting can be removed. Subsequently, the rotary table 52 resets, the fixing block 48 releases the pipe fitting, and the cutting machine 46 also retracts. The feeding device 2 moves forward, pushing the end of the pipe fitting back to the position of the bending mold 53. Then, the above steps will be repeated to realize the next bending and cutting operation, thereby forming a continuous and efficient bending and cutting process.

[0022] This design is ingenious. The combination of bending and cutting devices enables continuous bending and cutting of pipes, effectively improving production efficiency and making the pipe processing more efficient. It avoids the need for subsequent complex cutting of pipes, as well as the handling and loading of pipes after cutting when bending them. Through the coordinated work of the fixing block and the clamping mold, the pipes remain stable throughout the bending and cutting process, thus ensuring processing accuracy.

[0023] This invention is not limited to the specific embodiments described above. This 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.
