Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and more specifically, to a pipe cutting device. Background Technology

[0002] In the field of pipe processing and manufacturing, pipe cutting equipment is a key process tool. Its function is to precisely cut pipes of different specifications to meet the needs of various engineering construction and industrial production. With the continuous expansion of pipe application scenarios, more stringent requirements are being placed on the accuracy, efficiency, and stability of pipe cutting.

[0003] Currently, in the process of transporting pipe fittings to the pipe cutting device for cutting, the pipe cutting equipment on the market faces challenges. Due to the diverse dimensions of the pipe fittings, including differences in diameter, wall thickness, and length, these dimensional inconsistencies make it difficult for the fittings to maintain a stable posture and movement during transport.

[0004] Specifically, when the conveying device moves the pipe to be cut toward the pipe cutting device, the uneven distribution of friction, supporting force, and other forces between the pipe and the conveying device due to differences in pipe size makes the pipe prone to swaying and deviation during horizontal conveying. When the pipe moves to the side of the pipe cutting device, this unstable movement is further aggravated, easily causing the pipe to stop beside the pipe cutting device and making it difficult to smoothly enter the cutting device for cutting operations.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] Example 1 includes a pipe cutting device 1 and mounting frames 2 arranged on both sides of the pipe cutting device 1. The pipe cutting equipment also includes a conveying and lifting mechanism 3 and an auxiliary abutment mechanism 4. The conveying and lifting mechanism 3 is arranged beside a pair of mounting frames 2. The conveying and lifting mechanism 3 includes a first positioning plate 31, a rotating support roller 32 and a hydraulic cylinder 33. There are multiple first positioning plates 31, which are respectively arranged at the bottom of the mounting frames 2, and all of the multiple first positioning plates 31 are located below the mounting frames 2. There are multiple rotating support rollers 32, which are respectively arranged at the top of the mounting frames 2, and all of the multiple rotating support rollers 32 are conical structures, and all of the multiple rotating support rollers 32 are used to support the pipes to be cut. There are multiple hydraulic cylinders 33, which are respectively arranged at the bottom of the first positioning plates 31. When the hydraulic cylinders 33 are activated, they can drive the first positioning plates 31 and the mounting frames 2 to move upward. The auxiliary abutment mechanism 4 is arranged beside the mounting frames 2.

[0029] To address the issue of pipe fittings becoming stuck beside the cutting device 1 due to size differences during transport, a new method is used. First, the pipe fitting is placed on top of a rotating support roller 32 mounted on the mounting frame 2. The rotating support roller 32 then moves the pipe fitting horizontally. When the pipe fitting reaches the side of the cutting device 1, a hydraulic cylinder 33 is activated. This cylinder causes the first positioning plate 31 and the mounting frame 2 to rise synchronously, lifting the pipe fitting until it is level with the inlet of the cutting device 1. This prevents the pipe fitting from becoming stuck beside the cutting device 1.

[0030] See Figures 2-5 The conveying and lifting mechanism 3 also includes a mounting part 34 and a rotating shaft 35; the mounting part 34 has multiple parts and is respectively disposed on the top of the mounting frame 2, and the multiple mounting parts 34 are located on both sides of the rotating support roller 32; the rotating shaft 35 has multiple parts and is respectively rotatably disposed on the side of the multiple mounting parts 34, and the multiple rotating shafts 35 are fixedly connected to the rotating support roller 32, and when the rotating shaft 35 rotates, it can drive the rotating support roller 32 to rotate synchronously.

[0031] Specifically, a rotary motor, preferably a servo motor, can be installed on the end face of the rotating shaft 35 to ensure stable conveying of the pipe to be cut. The rotary motors should be spaced apart between each rotating shaft 35 and the mounting part 34. When the rotary motor is started, it can drive the rotating shaft 35 and the rotating support roller 32 to rotate, thereby enabling stable horizontal conveying of the pipe to be cut.

[0032] See Figures 2-5 The auxiliary contact mechanism 4 includes a mounting plate 41, a movable frame 42, and a rotating part 43. There are multiple mounting plates 41, which are respectively disposed on both sides of the mounting frame 2, and all mounting plates 41 are cuboid structures. There are multiple movable frames 42, which are respectively slidably mounted on the top of the mounting plates 41, and all movable frames 42 are located above the mounting frame 2. There are multiple rotating parts 43, which are respectively rotatably disposed on the top of the movable frames 42. When the rotating parts 43 rotate, they can be in contact with the outer side of the pipe to be cut.

[0033] Specifically, to prevent the pipe fittings from tilting and falling during the cutting process due to varying sizes, the top of the mounting plate 41 has a straight groove to limit the horizontal sliding of the moving frame 42, allowing the moving frame 42 to move stably along the groove. When a pair of moving frames 42 move towards the pipe fitting, they drive the rotating part 43 to move synchronously until the rotating part 43 comes into contact with the side of the pipe fitting. Then, the rotating part 43 rotates, bringing the two sides of the pipe fitting into contact. The rotating part 43's ability to rotate prevents the pipe fitting from tilting and does not affect the conveying of the pipe fitting.

[0034] See Figures 3-6 The auxiliary contact mechanism 4 also includes a first telescopic cylinder 44 and a connecting part 45; there are multiple first telescopic cylinders 44 and they are respectively installed at the bottom of the mounting plate 41, and the multiple first telescopic cylinders 44 are all located on the side of the mounting frame 2; there are multiple connecting parts 45 and they are respectively slidably installed on the top of the mounting plate 41, and the top of each connecting part 45 is fixedly connected to the movable frame 42, and the connecting part 45 is connected to the output end of the first telescopic cylinder 44.

[0035] Specifically, in order to adjust the moving distance of the movable frame 42, the first telescopic cylinder 44 is activated. When the first telescopic cylinder 44 is activated, it can drive the connecting part 45 and the movable frame 42 to move synchronously.

[0036] See Figure 5 The auxiliary contact mechanism 4 also includes a rotary driver 46; there are multiple rotary drivers 46 respectively disposed on the top of the movable frame 42, and the output ends of the multiple rotary drivers 46 are all connected to the rotating part 43. When the rotary driver 46 is started, it can drive the rotating part 43 to rotate.

[0037] Specifically, in order to drive the rotating part 43 to rotate and transport the pipe to be cut in the contact state, when the pipe to be cut is contacted by the rotating part 43, the rotary driver 46 is activated, which drives the rotating part 43 to rotate.

[0038] See Figure 4 The auxiliary abutment mechanism 4 also includes a fastening plate 47; there are multiple fastening plates 47 and they are respectively installed on the side of the setting plate 41, and the multiple fastening plates 47 are fixedly connected to the side of the first telescopic cylinder 44.

[0039] Specifically, the first telescopic cylinder 44 can be installed and removed between the fastener and the fastening plate 47.

[0040] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
