Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, specifically, it relates to a steel pipe elbow beveling cutting device. Background Technology

[0002] When welding thick steel plates, various bevel shapes are cut at the joint to ensure full penetration and facilitate the feeding of welding rods or wires. Beveling accuracy is a prerequisite for ensuring weld quality. Steel pipe elbows cannot be machined; the beveling of steel pipe elbows is usually done manually by cutting and grinding. Manual beveling results in uneven bevels, requiring further grinding, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of this invention is to solve the problems of uneven beveling and grinding that occur in existing technologies where manual cutting and grinding are required, which is time-consuming, labor-intensive, and inefficient. This invention provides a steel pipe elbow beveling cutting device that achieves uniform cutting, saves time and labor, and improves work efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel pipe elbow beveling cutting device, comprising a frame, a rotary table, a rotary motor, a flame cutting device, a rotating disk, and a clamping device; the rotary table is rotatably mounted on the frame via a short shaft, the rotary motor is mounted at the bottom of the frame and is connected to the rotary table via a transmission connection, the rotating disk is fixedly mounted on the rotary table, and the clamping device is evenly installed along the circumference of the rotating disk; the flame cutting device is mounted on one side of the frame via a support frame.

[0005] Furthermore, the rotating disk includes a support base, a connecting rod, and an annular support frame. The support base is fixedly installed on the rotating platform, and the annular support frame is connected and fixed to the support base through the connecting rod.

[0006] Furthermore, the clamping device includes a base and a clamping block. The base is slidably mounted on the connecting rod, and the clamping block is detachably mounted on the base by bolts. The clamping block is provided with support teeth that support the inner wall of the steel pipe.

[0007] Furthermore, the clamping device has a sliding groove at the bottom that matches the connecting rod. The clamping device can be slidably mounted on the connecting rod through the sliding groove. A threaded sleeve is fixed on the side of the clamping device. A lead screw is rotatably and axially limited on the annular support frame through a bearing. The lead screw is threadedly connected to the threaded sleeve.

[0008] Furthermore, the base is provided with a through hole, and the connecting rod is provided with a waist-shaped hole. The base can be slidably installed on the connecting rod through bolts and the waist-shaped hole.

[0009] The beneficial effects of this utility model are: (1) Uniform cutting: By rotating the screw, the position of the clamping device can be precisely adjusted to a certain extent, thereby adjusting the position of the steel pipe bend and ensuring the quality of the bevel cutting.

[0010] (2) High work efficiency: The structure is simple and easy to operate, realizing efficient cutting of steel pipe bends and bevels, which not only saves time and effort, but also reduces the labor intensity of workers. Attached Figure Description

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.

[0016] See Figure 1-3 A steel pipe bevel cutting device includes a frame 1, a rotary table 2, a rotary motor 3, a flame cutting device 4, a rotating disk 5, and a clamping device 6. The rotary table 2 is rotatably mounted on the frame 1 via a short shaft. The rotary motor 3 is mounted at the bottom of the frame 1 and is connected to the rotary table 2 via a transmission. The rotating disk 5 is fixedly mounted on the rotary table 2. The clamping device 6 is evenly installed around the rotating disk 5. The flame cutting device 4 is mounted on one side of the frame 1 via a support frame.

[0017] like Figure 1 As shown, the rotating disk 5 in this utility model includes a support base 51, a connecting rod 52, and an annular support frame 53. The support base 51 is fixedly installed on the rotating table 2, and the annular support frame 53 is connected and fixed to the support base 51 through the connecting rod 52.

[0018] like Figure 2As shown, the clamping device 6 of this utility model includes a base 61 and a clamping block 62. The base 61 is slidably mounted on the connecting rod 52, and the clamping block 62 is detachably mounted on the base 61 by bolts 8. The clamping block 62 is provided with support teeth 620 that support the inner wall of the steel pipe. During the cutting operation, the slag formed by the flame cutting device 4 will adhere to the clamping block 62, which may also cause deformation, burning or damage to the clamping block 62; it needs to be replaced regularly. The clamping block 62 is detachably mounted on the base 61, and only the clamping block 62 needs to be replaced, which reduces the replacement cost.

[0019] like Figure 2 As shown, the clamping device 6 has a sliding groove at its bottom that matches the connecting rod 52. The clamping device 6 is slidably mounted on the connecting rod 52 through the sliding groove. A threaded sleeve 10 is fixed to the side of the clamping device 6. A lead screw 7 is rotatably and axially limited on the annular support frame 53 through a bearing. The lead screw 7 is threadedly connected to the threaded sleeve 10. The base 61 has a through hole, and the connecting rod 52 has a waist-shaped hole 9. The base 61 is slidably mounted on the connecting rod 52 through bolts 8 and the waist-shaped hole 9. When the lead screw 7 is rotated, the threaded sleeve 10 on one side of the clamping device 6 moves along the axial direction of the lead screw 7, thereby driving the clamping device 6 to move linearly, realizing the clamping and fixing of steel pipe elbows of different diameters.

[0020] The working principle of this utility model is as follows: The steel pipe to be cut is placed on the clamping block 62, and the inner wall of the steel pipe is supported and fixed by the support teeth 620; the screw 7 is adjusted according to the diameter of the steel pipe. When the screw 7 is rotated, the threaded sleeve 10 moves along the axial direction of the screw 7, thereby driving the clamping device 6 to move linearly on the connecting rod 52. After adjusting the position of the steel pipe bend, the rotary motor 3 and the flame cutting device 4 can be started to achieve efficient cutting of the steel pipe bend bevel. This not only saves time and effort and reduces the labor intensity of workers, but also ensures the quality of the steel pipe bevel cutting.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
