[0002] Oil casing couplings are important components used to connect oil casings in the petroleum industry. Their main function is to connect two sections of oil casings to form a continuous pipeline system. Oil casing couplings are widely used in industries such as oil drilling and production, oil refining and chemical engineering, and play an important role in ensuring the safe transportation and efficient exploitation of oil and natural gas.
[0003] The specific production and processing process of oil casing couplings is as follows: First, purchase the pipe material for oil casing couplings. The pipe material is generally a whole round pipe body with the same length. Then, use a pipe material cutting device to cut it into coupling original pipes according to the dimensions of the design drawing. Finally, tap the inner wall surfaces at both ends of each cut coupling original pipe to form the finished oil casing couplings. Later, the finished oil casing couplings can be threadedly connected to the external threads preset on the outer wall of the oil casing.
[0004] Currently, most of the existing pipe material cutting devices for oil casing couplings cannot perform lateral adjustment of the limit baffle according to design requirements, and thus cannot cut into coupling original pipes of different lengths, reducing the applicability of the limit baffle on the pipe material cutting device for oil casing couplings.

Specific embodiments
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0026] Refer to Figures 1-5 , a pipe material cutting device for oil casing couplings, including a cutting table 4, a cutting groove 41 is provided on the cutting table 4, a bottom plate 1 is provided below the cutting table 4, a feeding group 2 is provided on the bottom plate 1, the feeding group 2 is composed of a feeding belt 21 and a feeding motor 22, a support frame 5 and a material receiving box 3 are provided on the bottom plate 1, a cutting cylinder 51 is provided on the support frame 5, and a cutting knife 52 is arranged on the cutting cylinder 51;
[0027] A fixing frame 6 is provided on the support frame 5, a guide chute 62 is provided on the fixing frame 6, a transverse slide plate 8 is slidably connected in the guide chute 62, an adjusting screw 7 and a controller 61 are provided on the fixing frame 6, a turning handle 71 is provided on the adjusting screw 7, and a limit baffle 81 is provided on the transverse slide plate 8;
[0028] A feeding guide groove 23 is provided on the feeding belt 21, an anti-slip damping layer 24 is provided in the feeding guide groove 23, casters 31 and a material guiding slide plate 32 are provided on the material receiving box 3. The feeding group 2 is a common conveying device for pipe bodies. The feeding belt 21 and the feeding motor 22 are both existing structures. The cutting table 4, the cutting cylinder 51, and the cutting knife 52 are all existing technologies. Some existing structures are not drawn and marked and need not be described in detail.
[0029] The upward view cross-section of the guide chute 62 is a rectangular groove and is in sliding contact with the upper end surface of the transverse slide plate 8. The lower end surface of the limit baffle 81 is horizontally aligned with the upper end surface of the cutting table 4. When the adjusting screw 7 rotates, it drives the transverse slide plate 8 to slide along the guide chute 62, preventing the transverse slide plate 8 and the limit baffle 81 from rotating.
[0030] The cutting groove 41 runs longitudinally through the cutting table 4. The cutting groove 41 is vertically aligned with the cutting knife 52, enabling the cutting knife 52 to quickly and accurately insert downward into the cutting groove 41 without contacting the inner wall of the cutting groove 41, thus ensuring the overall cutting of the pipe material.
[0031] The rotating handle 71 is arranged at the right end of the adjusting screw 7. The adjusting screw 7 is rotatably arranged with the fixed frame 6 and is threadedly connected to the transverse sliding plate 8. Through threaded transmission, the effect of horizontally translating the limiting baffle 81 left and right is achieved.
[0032] A bearing 63 is embedded in the fixed frame 6. The preset mounting hole of the bearing 63 is fixedly sleeved with the adjusting screw 7. The bearing 63 is a ball bearing, preventing the adjusting screw 7 from experiencing lateral slippage.
[0033] The side cross-section of the material conveying guide groove 23 is an arc-shaped inner groove. The anti-slip damping layer 24 is evenly coated along the inner groove wall of the material conveying guide groove 23. The anti-slip damping layer 24 is made of a silicone coating material, which can further stably damp and prevent slip during the conveying of the pipe material placed in the material conveying guide groove 23.
[0034] The casters 31 are four symmetrically arranged and are arranged at the lower end of the receiving box 3. The material guiding sliding plate 32 is inclined towards the cutting table 4. The casters 31 are universal braking wheels.
[0035] The upper end surface of the material guiding sliding plate 32 is horizontally aligned with the end surface of the cutting table 4, achieving stable limiting and blocking of the right end surface of the pipe material to ensure subsequent cutting.
[0036] Working method: First, place the pipe material in the material conveying guide groove 23, and then start the controller 61. The PLC in the controller 61 will control the start of the material conveying motor 22 to drive the material conveying belt 21 to run, and stably convey the pipe material placed in the material conveying guide groove 23 from left to right. When the right end surface of the pipe material contacts the left end surface of the limiting baffle 81, the PLC in the controller 61 will control the stop of the material conveying motor 22 and control the start of the cutting cylinder 51 to drive the cutting knife 52 to quickly move downward. When the cutting knife 52 is inserted into the cutting groove 41, the PLC in the controller 61 will control the start of the cutting cylinder 51 and achieve the quick upward reset of the cutting knife 52. At the same time, the cutting knife 52 will quickly cut the positioned pipe material into a section of coupling original pipe, and this section of coupling original pipe will slide into the receiving box 3 along the material guiding sliding plate 32 for storage. This is the prior art;
[0037] According to the design requirements, when it is necessary to cut the coupling original pipe with shorter or longer dimensions, the handle 71 can be rotated clockwise or counterclockwise, driving the adjusting screw 7 to rotate clockwise or counterclockwise. Through the thread transmission, the transverse slide plate 8 will be driven to slide left or right along the material guiding slide plate 32, and then drive the limit baffle 81 to slide left or right horizontally. When adjusted to the appropriate position, stop rotating the handle 71. At this time, the electric control cutting operation of the pipe material can be carried out, and the coupling original pipe can be cut into different lengths, effectively improving the applicability of the limit baffle 81 on the pipe material cutting device for oil casing couplings.
[0038] In addition, when the pipe material is placed in the material conveying guide groove 23 and conveyed from left to right, combined with the anti-slip damping layer 24, the conveying group 2 can horizontally and stably and accurately translate the pipe material to between the cutting knife 52 and the cutting groove 41, greatly improving the conveying stability and accuracy of the pipe material.
[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
