Description

Technical Field

[0001] The utility model belongs to the technical field of gas cylinder processing, and in particular relates to a pipe cutting device. Background Art

[0002] The most common medical gas cylinders are oxygen cylinders used in hospitals, or CNG cylinders, which are mainly used to store compressed natural gas. The processing of gas cylinders usually involves cutting large steel pipes, welding the heads and tails, and grinding the welding positions or other defective positions. When cutting steel pipes, due to the large diameter of the gas cylinders, large steel pipes are used to cut and segment according to the length of the gas cylinders. Due to the large mass and size of such steel pipes, when using existing pipe cutting devices, due to the long length of the pipes, the remaining pipes need to be moved and re-limited after cutting. Therefore, the movement is extremely inconvenient, resulting in low efficiency in pipe cutting. Utility Model Content

[0003] In view of the above-mentioned deficiencies, the purpose of the present utility model is to provide a pipe cutting device, which solves the problem in the prior art that it is inconvenient to move and re-limit the pipe when cutting large pipes, thereby causing low cutting efficiency.

[0024] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] See also Figures 1 to 3A pipe cutting device is mainly used for cutting large pipes, such as pipes made in gas cylinders. The cutting device includes a processing platform 1, on which a cutter 2 is movably provided. The cutter 2 can be a laser cutter, and the position of the cutter 2 can be adjusted according to the optimal cutting position. A placement rack 3 for placing pipes 100 is provided on one side of the cutter 2, and the placement rack 3 is movably provided on the processing platform 1. The placement rack 3 is mainly used to place pipes 100. After the cutting is completed, the pipes 100 can be moved, and the position of the pipes 100 can be adjusted to facilitate the next step of cutting. A driving mechanism 4 for driving the pipes 100 to rotate is provided on the placement rack 3. During cutting, the pipes 100 are driven to rotate by the driving mechanism 4 to facilitate the ring cutting process. A supporting mechanism 5 that moves in the same straight line with the placement rack 3 is provided on one side of the placement rack 3 to support and move the pipes 100. In this embodiment, the above-mentioned design can ensure that the support mechanism 5 can play a supporting role during cutting, and can play a lifting and moving role when the cutting is completed. Since the placement rack 3 is provided with a structure for driving the pipe fitting 100 to rotate, if the pipe fitting 100 is pushed to move directly through the rear placement rack 3, it is bound to cause wear of the driving structure on the placement rack 3 that contacts the pipe fitting. Therefore, in this application, when adjusting the position of the pipe fitting 100, the support mechanism 5 is first used to lift it to a certain height, and then the pipe fitting 100 is separated from the placement rack 3, and then the pipe fitting 100 is moved.

[0027] In this embodiment, the cutter 2, the placement rack 3 and the support mechanism 5 are all driven by linear motors to move on the track 1a set on the processing platform 1, and the cutter 2, the placement rack 3, the support mechanism 5 and the linear motor are all electrically connected through an external controller and automatically controlled by a PLC control system.

[0028] Two placement racks 3 are arranged on the processing platform 1 to support and limit the ends of the pipe 100, and one of the placement racks 3 is provided with the driving mechanism 4, which is a driving motor in this embodiment. The supporting mechanism 5 is arranged between the two placement racks 3 and at the rear position. After the cutting is completed at the front end, the lengths of the pipes 100 at both ends can be kept as similar as possible, thereby maintaining balance during the lifting movement.

[0029] Please continue reading Figure 2The lower end of the placing frame 3 is slidably connected with the processing platform 1, and a driving shaft 3a is provided in the middle of the upper end, and a limiting frame 3b is provided on both sides of the driving shaft 3a. One end of the driving shaft 3a is driven to rotate by a driving mechanism 4 provided at one end of the placing frame 3, and a limiting plate 31a is provided at the outer end of the driving shaft 3a to limit the top of the pipe 100. Specifically, the placing frame 3 includes an I-shaped mounting frame 3f, the lower end of the mounting frame 3f is slidably mounted on the track 1a, and the two ends of the driving shaft 3a are mounted in the middle of the mounting frame 3f through bearings and can contact the bottom of the pipe 100, and the surface of the driving shaft 3a has a certain friction force, which drives the pipe 100 to rotate when in contact with it. The two ends of the limiting frame 3b are rotatably mounted on the ends of the mounting frame 3f through an adjusting plate 3c, and the lower end of the adjusting plate 3c is locked and fixed by a locking member 3d. The limiting frame 3b is movably provided with a movable roller 3e, which contacts and guides the side wall of the pipe 100. Since the rotation of the pipe is driven by the driving shaft 3a below, the limiting frames 3b on both sides need to contact and limit the two sides of the pipe 100, thereby ensuring the stability of the rotation of the pipe 100. When limiting the pipes 100 of different sizes, the angle of the limiting frame 3b can be adjusted, thereby improving the versatility of the cutting device.

[0030] See also Figure 3 Furthermore, the locking member 3d is only provided on one side of the placement frame 3 to fix the limiting frame 3b. The locking member 3d includes a connecting member 31d and a screw rod 32d. The connecting member 31d is rotatably connected to the lower ends of the adjustment plates 3c on both sides. The two ends of the screw rod 32d are provided with opposite threads, and the two ends of the screw rod 32d are threadedly connected to the connecting member 31d. One end of the screw rod 32d is provided with a manual adjustment disk 33d. The two ends of the screw rod 32d are arranged in opposite directions to the thread setting direction of the connecting member 31d, thereby ensuring that the connecting block 31d can move toward each other, move closer to each other or move away from each other during adjustment.

[0031] Please continue reading Figure 2 Specifically, the lower end of the support mechanism 5 is slidably connected to the track 1a on the processing platform 1, and the upper end is provided with a lifting cylinder 5a. The upper end of the lifting cylinder 5a is connected to the support plate 5b of the arc structure and contacts the pipe 100. The support mechanism 5 is arranged near the rear end placement rack 3, and after the cutting of the previous section of the pipe is completed, it can be ensured to be in the middle position as much as possible, and the balance of both ends can be ensured during the transfer. The setting of the support mechanism 5 is mainly considered that when the heavy pipe 100 moves forward, if it moves close to the drive shaft 3a, it is bound to cause damage to the drive shaft 3a. Therefore, the mechanism is used to lift it upward to separate from the placement rack 3 and move forward and place it at a designated position for subsequent cutting processing.

[0032] The working principle of the utility model is as follows:

[0033] In the process of processing CNG gas cylinders, it is necessary to cut the steel pipe into corresponding sizes and then weld the ends. Since the steel pipe for processing the gas cylinder is a large steel pipe with a large weight, the cutting device dedicated to large pipe fittings of the present application is used. First, the pipe fitting 100 is hoisted on the placement rack 3 by the hoisting mechanism. The ends of the steel pipe 100 are placed on the placement rack 3 respectively, and then the driving shaft 3a is driven to rotate by the driving mechanism 4, and the driving shaft 3a in contact with the pipe fitting 100 drives the pipe fitting 100 to rotate. At this time, the cutter 2 adjusts the position and cuts the pipe fitting 100. After the cutting is completed, the cut pipe fitting is unloaded, and the pipe fitting 100 is lifted by the lifting cylinder 5a of the support mechanism 5 and the two ends of the pipe fitting 100 are placed on the placement rack 3 after adjusting the position by the linear motor, and the cutting process is completed again. The cutting device of the utility model can adjust the position of the pipe fitting 100 when cutting pipe fittings with large weight and large size, thereby improving the cutting efficiency.

[0034] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementations disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model. Other devices that are the same or similar to them are all within the protection scope of the utility model.
