Description

Technical Field

[0001] The utility model relates to the technical field of cutting mechanisms such as pipelines and pipe bodies in the mechanical field, in particular to a pipeline cutting device. Background Art

[0002] In the prior art, in the technical solution for pipe cutting, the structural setting is usually relatively simple. On the one hand, the pipe needs to be fixed by tooling and other equipment, and on the other hand, the cutting is performed accordingly. Blade cutting, wire cutting, etc. can be selected for cutting, or more advanced laser cutting and other technologies can be selected.

[0003] Therefore, in the prior art, the more important aspect of the pipeline cutting technology is how to correspondingly set up the fixing mechanism of the pipeline and the tooling and other equipment that cooperates with the cutting mechanism for cutting.

[0004] For example, the technical solution with the publication (announcement) number CN218226896U discloses "a pipe cutting machine". The cutting mechanism in the technical solution uses a cutting wheel for cutting, and a threaded bearing clamp is provided to fix the pipe and achieve cutting.

[0005] For example, the technical solution with the publication (announcement) number CN210024051U discloses “an automatic pipe cutting machine”, in which a clamping module, a rotating mold and a positioning mold are provided to clamp and fix the pipe, thereby realizing automatic cutting of the pipe.

[0006] However, in most of the above-mentioned technical solutions and existing technical solutions, the pipe is directly fixed from the outside by a clamp. On the one hand, the position of the pipe cannot be moved or rotated, and it cannot cooperate well with the cutting mechanism for cutting; on the other hand, the cutting range and application scope of the cutting device cannot be expanded, which affects the cutting efficiency and cutting quality.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a pipe cutting device with a reasonable structure and improved cutting quality and efficiency. Utility Model Content

[0012] Furthermore, the cutting mechanism itself has a lifting function, and the cutting mechanism is correspondingly provided with a laser cutting mechanism or a knife-type mechanical cutting mechanism.

[0013] Furthermore, support rods are provided on both the left and right sides of the fixing seat, and support arc plates are installed on the ends of the support rods, so that the pipeline above can be supported accordingly.

[0014] Furthermore, the support rod is configured as a telescopic rod structure with adjustable height, and the support rod itself has a height adjustment locking function.

[0015] Furthermore, the supporting arc plate is also provided with embedded balls, and the pipe is correspondingly placed on the balls. When the pipe rotates, the pipe rotates under the support of the balls.

The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a pipe cutting device of the present embodiment comprises a fixed seat 1 at the bottom, a double-headed motor 2 is arranged at the middle position of the fixed seat 1, screw rods 3 are installed at both ends of the double-headed motor 2, and a moving seat 4 is also arranged on both sides of the fixed seat 1 of the present embodiment, and screw rod seats 5 are installed at the lower ends of the moving seats 4 on both sides, the screw rods 3 on both sides are installed correspondingly to the screw rod seats 5, and the thread directions on the screw rods 3 on both sides are set accordingly, when the double-headed motor 2 is turned on, it drives the screw rods 3 on both sides to rotate, so that the moving seats 4 and the screw rod seats 5 on both sides move inward or outward at the same time;

[0033] The movable seats 4 on both sides are also equipped with rotating motors 6. The main shaft 7 of the rotating motor 6 extends laterally inward, and the shaft ends are correspondingly equipped with vertical rotating circular plates 8. The inner sides of the rotating circular plates 8 on both sides are correspondingly provided with pipe fixing tools 9. Under the action of the pipe fixing tools 9, the pipe 11 to be cut is fixed between the rotating circular plates 8 on both sides, and rotates accordingly under the action of the rotating motors 6 on both sides.

[0034] The fixing seat 1 of the present embodiment is further provided with a cutting mechanism 10 , and the position of the cutting mechanism 10 corresponds to the position of the pipe 11 placed above. The cutting mechanism 10 can cut the pipe 11 above accordingly.

[0035] The cutting mechanism 10 of this embodiment has a lifting function, and the cutting mechanism 10 is correspondingly provided with a laser cutting mechanism or a knife-type mechanical cutting mechanism.

[0036] In this embodiment, support rods 12 are provided on both the left and right sides of the fixing seat 1 , and support arc plates 13 are installed at the ends of the support rods 12 , so that the pipe 11 above can be supported accordingly.

[0037] The support rod 12 of the present embodiment is configured as a telescopic rod structure with adjustable height, and the support rod 12 of the present embodiment itself has a height adjustment locking function.

[0038] In this embodiment, an embedded ball bearing 14 is further provided on the supporting arc plate 13 , and the pipe 11 in this embodiment is correspondingly placed on the ball bearing 14 . When the pipe 11 rotates, the pipe 11 rotates correspondingly under the support of the ball bearing 14 .

[0039] In this embodiment, track mechanisms 15 are further provided on both sides of the fixed seat 1, and the movable seats 4 on both sides are correspondingly embedded in the track mechanisms 15. With the cooperation of the track mechanisms 15, the movable seats 4 can move left and right.

[0040] The specific working principle of the technical solution of this embodiment is as follows: during specific work, the pipes are placed on the supporting arc plates on both sides respectively. The positions of the supporting arc plates on both sides can be adjusted accordingly under the action of the supporting rods, and are adjusted to the height corresponding to the position of the rotating circular plates on both sides according to the size of the pipes to be cut.

[0041] Then turn on the double-headed motor in the middle position, and the double-headed motor will drive the screws on both sides to rotate accordingly, so the screw seats on the screws will move accordingly. At this time, it should be noted that the thread directions on the screws on both sides need to be set to correspond, and the screw seats on both sides can move inward or outward at the same time.

[0042] After the screw seat moves, the moving seat installed as an integral part of the screw seat also moves together. After the moving seat moves inward, it drives the rotating motor and the rotating circular plate to move inward accordingly, and sends the pipe fixing tooling to both side ends of the pipe. The pipe fixing tooling fixes the pipe from the inside at both side ends. In this process, the pipe is subjected to pressure from the rotating circular plates on both sides in the axial direction and pressure from the pipe fixing tooling in the radial direction, so that the position of the pipe is fixed and can rotate with the rotating motor.

[0043] At the same time, a cutting mechanism is arranged on the fixed seat, and the cutting mechanism itself has a lifting function. When the position of the pipeline is fixed, the pipeline can be cut by the cutting mechanism, and the pipeline slowly rotates with the rotating motor, and finally the pipeline is cut.

[0044] The cutting mechanism of the device is a cutting mechanism in the prior art, and can be selected as a laser cutting mechanism, or other cutting mechanisms, which can ensure the completion of the cutting work.
