Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to a positioning component and a seamless steel pipe cutting device. Background Art

[0002] Seamless steel pipe is a kind of pipe, which is characterized by the fact that the entire steel pipe is formed by perforating, stretching or extruding round steel raw materials through a specific process, and there are no welding marks on the surface, so it is called "seamless".

[0003] At present, in order to prevent the seamless steel pipe from moving when being cut, a positioning component is usually provided on the cutting device to fix the seamless steel pipe.

[0004] However, since the positioning assembly usually fixes and clamps the seamless steel pipe, the contact area between the blade and the steel pipe will gradually increase when the blade cuts the steel pipe, thereby increasing the risk of the blade breaking. Therefore, the utility model proposes a positioning assembly and a seamless steel pipe cutting device for solving the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning component and a seamless steel pipe cutting device to solve the problem raised in the above background technology that the positioning component usually fixes and clamps the seamless steel pipe, so that the contact area between the blade and the steel pipe gradually increases when the blade cuts the steel pipe, thereby increasing the risk of blade breakage.

[0006] To achieve the above object, the utility model provides the following technical solution: a positioning component, the positioning component comprising:

[0007] A mounting platform, wherein the upper side of the mounting platform is rotatably connected to a mounting tube, a side of the mounting tube is fixedly connected to a gear ring, a side of the gear ring is meshed with a gear driven to rotate by a motor, and an inner cavity of the mounting tube is provided with a clamping assembly for fixing a seamless steel tube;

[0008] The clamping assembly includes a No. 1 clamping plate and multiple No. 2 clamping plates. The No. 1 clamping plate is located in the inner cavity of the mounting tube and is fixedly connected to the mounting tube. Multiple No. 2 clamping plates are located in the inner cavity of the mounting tube and are slidably connected to the mounting tube. The side of the No. 2 clamping plate is fixedly connected to a connecting rod configured to be a "polygonal". The connecting rod and the mounting tube are slidably plugged in and one end of the connecting rod is fixedly connected to a hydraulic cylinder. The hydraulic cylinder is located on the outside of the mounting tube and is fixedly connected to the mounting tube.

[0009] Preferably, a plurality of support plates for supporting the mounting tube are fixedly connected to the side surface of the mounting platform, and the mounting tube and the plurality of support plates are rotatably connected.

[0010] Preferably, a limiting groove is provided on the side of the support plate, and a plurality of positioning blocks adapted to the limiting groove are fixedly connected to the side of the mounting tube.

[0011] Preferably, the No. 1 splint is arranged in a "V" shape, and the plurality of No. 2 splints are all arranged in a "V" shape.

[0012] Preferably, a mounting frame is fixedly connected to the side of the mounting tube, the hydraulic cylinder and the mounting frame are fixedly connected, and a slot for sliding a connecting rod is provided on one side of the mounting tube.

[0013] A seamless steel pipe cutting device comprises the above-mentioned positioning assembly.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The device fixes the seamless steel pipe inside the installation pipe through a clamping component, and then drives the installation pipe to perform periodic forward and reverse rotation through a combination of a gear ring, a gear and a motor. When the installation pipe rotates, the seamless steel pipe can be driven to rotate together. Each time the blade cuts to the inner hole, the blade can be slid out of the steel pipe. At this time, the seamless steel pipe is allowed to rotate regularly with the installation pipe, and then cut again. By doing so many times, the cutting of the seamless steel pipe can be completed while reducing the contact area between the blade and the steel pipe, thereby improving the safety of the blade during cutting. This also solves the problem that the positioning component usually fixes and clamps the seamless steel pipe, thereby gradually increasing the contact area between the blade and the steel pipe when cutting the steel pipe, thereby increasing the risk of blade breakage.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] Embodiment 1, a positioning component, the positioning component includes: a mounting platform 1.

[0027] Specifically, the upper side of the mounting platform 1 is rotatably connected with a mounting tube 3, the side of the mounting tube 3 is fixedly connected with a gear ring 4, the side of the gear ring 4 is meshed with a gear 5 driven to rotate by a motor 6, and the inner cavity of the mounting tube 3 is provided with a clamping assembly for fixing a seamless steel pipe;

[0028] Furthermore, the clamping assembly includes a No. 1 clamping plate 7 and a plurality of No. 2 clamping plates 8. The No. 1 clamping plate 7 is located in the inner cavity of the mounting tube 3 and is fixedly connected to the mounting tube 3. The plurality of No. 2 clamping plates 8 are all located in the inner cavity of the mounting tube 3 and are slidably connected to the mounting tube 3. The side of the No. 2 clamping plate 8 is fixedly connected to a connecting rod 91 arranged in a "polygonal" shape. The connecting rod 91 is slidably plugged into the mounting tube 3 and one end of the connecting rod 91 is fixedly connected to a hydraulic cylinder 9. The hydraulic cylinder 9 is located on the outside of the mounting tube 3 and is fixedly connected to the mounting tube 3. In actual implementation, the seamless steel pipe is first inserted into the inner cavity of the mounting tube 3, and then the hydraulic cylinder 9 pushes the connecting rod 91 to slide after determining the cutting length, thereby pushing the No. 2 clamping plate 8 to slide. The No. 1 clamping plate 8 slides, and the seamless steel pipe can be clamped on the inner side of the mounting tube 3 through the No. 2 clamping plate 8 and the No. 1 clamping plate 7. After the seamless steel pipe is fixed, the blade can be operated to cut the seamless steel pipe. When the blade cuts to the inner hole, the cutting is stopped, and the blade is slid out of the seamless steel pipe. Then the motor 6 drives the gear 5 to make regular forward and reverse movements. The rotation of the gear 5 will drive the gear ring 4 to rotate, and the rotation of the gear ring 4 will drive the mounting tube 3, and finally drive the seamless steel pipe fixed on the mounting tube 3 to rotate. After the rotation, the blade can be allowed to cut the seamless steel pipe again from the surface of the seamless steel pipe, so that the contact surface of the blade entering the steel pipe becomes smaller. Repeat the operation several times to complete the cutting of the steel pipe.

[0029] In order to facilitate the rotational installation of the mounting tube 3, a plurality of support plates 2 for supporting the mounting tube 3 are fixedly connected to the side of the mounting platform 1 of the present application. The mounting tube 3 and the plurality of support plates 2 are all rotationally connected. The plurality of support plates 2 can provide the mounting tube 3 with an installation height and can also provide support for the mounting tube 3.

[0030] In order to ensure the stability of the mounting tube 3, a limiting groove 21 is provided on the side of the support plate 2 of the present application, and a plurality of positioning blocks 32 adapted to the limiting groove 21 are fixedly connected to the side of the mounting tube 3. Through the cooperation between the positioning blocks 32 and the limiting groove 21, the mounting tube 3 can be prevented from sliding without affecting the rotation of the mounting tube 3.

[0031] In order to further ensure the stability of the installation of the seamless steel pipe, the No. 1 splint 7 of the present application is set in a "V" shape, and multiple No. 2 splints 8 are all set in a "V" shape. This can increase the contact area between the No. 1 splint 7, the No. 2 splint 8 and the seamless steel pipe, thereby further preventing the seamless steel pipe from slipping during the cutting process.

[0032] In order to facilitate the installation of the hydraulic cylinder 9, a mounting bracket 31 is fixedly connected to the side of the mounting tube 3 of the present application, the hydraulic cylinder 9 and the mounting bracket 31 are fixedly connected, and a slot 33 for the connecting rod 91 to slide is opened on one side of the mounting tube 3. The mounting bracket 31 can give the hydraulic cylinder 9 an installation height, and the slot 33 can better cooperate with the sliding insertion of the connecting rod 91.

[0033] The present application also discloses a seamless steel pipe cutting device, comprising the above-mentioned positioning assembly.
