Description

Technical Field

[0001] This invention relates to the technical field of steel pipe processing, and in particular to a high-efficiency processing device for spiral steel pipes. Background Technology

[0002] Spiral steel pipes are widely used in oil, natural gas, urban pipeline networks, and structural piles due to their high strength and low cost. During construction, long pipes need to be cut to specified lengths according to design requirements.

[0003] The existing spiral steel pipe cutting technology mainly has the following problems: Poor clamping adaptability: Traditional cutting machine clamping mechanisms are usually fixed or manually adjustable, making it difficult to quickly adapt to steel pipes of different diameters. When cutting large-diameter or thick-walled pipes, vibrations and displacements caused by unstable clamping can directly affect the cut quality and even damage the equipment.

[0004] Insufficient support for long pipes: Spiral steel pipes are typically 12 meters or longer. During rotary cutting, long pipes are prone to bending and deformation due to gravity, especially the swaying in the middle and tail of the pipe. This not only affects cutting accuracy but also poses safety hazards. Existing equipment lacks flexible adjustable auxiliary supports and cannot find the optimal support balance point for pipes of different lengths.

[0005] Separation of cooling and dust removal: Physical cutting with blades generates a large amount of high-temperature chips and dust. Existing equipment either only has simple air cooling, which is ineffective and easily causes dust to rise; or it only has a dust collection device, which cannot solve the problems of high-temperature blade wear and workpiece thermal deformation. The cooling and dust removal systems are independent, occupy a lot of space, and have poor coordination. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] In view of the problems existing in the above-mentioned high-efficiency processing devices for spiral steel pipes, the present invention is proposed.

[0008] Therefore, the purpose of this invention is to provide a high-efficiency processing device for spiral steel pipes, the purpose of which is to: *improve the adaptability and stability of processing.

[0009] To solve the above technical problems, the present invention provides the following technical solution: a support body, wherein a sliding groove is provided inside the support body, and a movable block is slidably disposed inside the sliding groove. The movable block is provided in two sets and is arranged symmetrically. A long groove is provided on the top of the movable block, a first square groove is provided on one side of the movable block, and a second square groove is provided on the other side of the movable block.

[0010] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, a connecting block is provided inside the long groove, an extrusion plate is provided on one side of the top of the connecting block, a bidirectional screw is threadedly connected to the top of the connecting block, and the bidirectional screw is driven by a motor provided on one side thereon.

[0011] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, a second cylinder is fixedly installed inside the first square groove, a connecting shell is provided on one side of the second cylinder, and a first cylinder is fixedly installed inside the connecting shell.

[0012] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, an auxiliary support block is provided at the output end of the first cylinder, and the support contact surface of the auxiliary support block is set at a certain arc angle.

[0013] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, a support frame is provided on the top of the support body, a liquid storage tank is provided inside the support frame, and a third cylinder is fixedly provided on the top of the support frame.

[0014] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, the top of the support frame is slidably connected to a limiting rod, and multiple sets of the limiting rod are provided.

[0015] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, a square block is fixedly connected to the bottom of the limiting rod, and the bottom of the third cylinder is also connected to the top of the square block.

[0016] In a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, a cutting motor is provided inside the square block, and a cutting blade is provided on one side of the cutting motor.

[0017] As a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, the square block is provided with air suction heads on both sides of its bottom, one side of the square block is connected to a telescopic pipe, and the telescopic pipe is connected to the bottom of an air pump.

[0018] As a preferred embodiment of the high-efficiency spiral steel pipe processing device of the present invention, a pressure block is provided on one side of the bottom of the liquid storage tank, a pressure ring is fixedly provided on one side of the pressure block, a flow port is provided inside the pressure ring, a return spring is provided at the bottom of the pressure ring, a water outlet pipe is slidably provided inside the pressure ring, a connecting port is provided on one side of the water outlet pipe, and a telescopic water pipe is provided at the top of the pressure ring.

[0019] The beneficial effects of this invention are as follows: By driving two sets of connecting blocks synchronously with a bidirectional screw, the clamping distance can be quickly adjusted, adapting to spiral steel pipes of different diameters. Simultaneously, the combination of "rotating block drive + extrusion disc assistance" provides rotational power, while the extrusion disc provides radial restraint from both sides, effectively preventing the steel pipe from swaying during rotation and improving cutting stability. To address the issue of varying spiral steel pipe lengths, an auxiliary support block is installed, driven axially by a second cylinder and lifted by a first cylinder. The support point position can be flexibly adjusted according to the steel pipe length to find the optimal balance point, effectively suppressing the sag and rotational sway of the long pipe cantilever end, significantly improving the straightness and end-face flatness of long pipe cutting. The dust extraction function is integrated into a square block above the cutting blade, achieving source adsorption of chips and improving the working environment. Furthermore, an innovative mechanical linkage water circuit triggered by the descent of the square block is designed. The water circuit automatically activates only when the cutting blade descends to the working position (when the square block presses down), achieving "spraying as you cut and stopping as you stop," thus avoiding waste of cutting fluid. The dust extraction air duct and the water spray circuit are independent of each other and do not interfere with each other. The air extraction head is responsible for removing dust, while the water spray head is responsible for cooling and lubrication. The two work together to solve the contradiction in traditional equipment where "dust extraction affects cooling" or "cooling exacerbates dust." Attached Figure Description

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0030] Reference Figures 1-6 As one embodiment of the present invention, a high-efficiency processing device for spiral steel pipes is provided, comprising: The support body 1 has a sliding groove 11 inside. Two sets of movable blocks 2 are slidably disposed within the sliding groove 11. Each movable block 2 has a long groove 21 on its top, a first square groove 22 on one side, and a second square groove 23 on the other side. A connecting block 211 is disposed inside the long groove 21. A pressing disc 212 is disposed on one side of the top of the connecting block 211. A bidirectional screw 213 is threadedly connected to the top of the connecting block 211 and is driven by a motor disposed on one side. A second cylinder 234 is fixedly disposed inside the first square groove 22. A connecting shell 233 is disposed on one side of the second cylinder 234, and a first cylinder 232 is fixedly disposed inside the connecting shell 233. An auxiliary support block 231 is disposed at the output end of the first cylinder 232, and the supporting contact surface of the auxiliary support block 231 is set at a certain arc angle.

[0031] The spiral steel pipe is provided with good support and clamping effect by two sets of extrusion discs 212, auxiliary support block 231, and rotating block 221. The rotating rod 222 is driven to rotate by the drive motor 223, thereby rotating the rotating block 221. The two sets of extrusion discs 212 can rotate freely, thereby driving the spiral steel pipe to rotate.

[0032] When adjustment is required, the bidirectional screw 213 is driven to rotate by the motor, so that the two sets of connecting blocks 211 move closer or further apart, thereby adapting to spiral steel pipes of different diameters.

[0033] Since the spiral steel pipes are of different lengths, the position of the auxiliary support block 231 needs to be adjusted to adjust the balance point, that is, to ensure the stability during the cutting process. Specifically, the second cylinder 234 drives the connecting shell 233 to move, which in turn drives the auxiliary support block 231 to move. The first cylinder 232 can adjust the height of the auxiliary support block 231, thus facilitating the adjustment of its position.

[0034] A support frame 3 is mounted on the top of the support body 1. A liquid storage tank 31 is housed inside the support frame 3. A third cylinder 32 is fixedly mounted on the top of the support frame 3. Multiple limit rods 33 are slidably connected to the top of the support frame 3. A square block 34 is fixedly connected to the bottom of the limit rod 33, and the bottom of the third cylinder 32 is connected to the top of the square block 34. A cutting motor 35 is housed inside the square block 34, and a cutting blade 36 is mounted on one side of the cutting motor 35. Suction heads 37 are mounted on both sides of the bottom of the square block 34, and a telescopic pipe 38 is connected to one side of the square block 34, which in turn connects to the bottom of an air pump 39. A pressure block 311 is provided on one side of the bottom of the liquid storage tank 31. A pressure ring 312 is fixedly provided on one side of the pressure block 311. A flow port 3121 is provided inside the pressure ring 312. A return spring 3122 is provided at the bottom of the pressure ring 312. A water outlet pipe 313 is slidably provided inside the pressure ring 312. A connecting port 3131 is provided on one side of the water outlet pipe 313. A telescopic water pipe 314 is provided at the top of the pressure ring 312.

[0035] The cutting motor 35 drives the cutting blade 36 to rotate, thereby cutting the pipe. The third cylinder 32 drives the square block 34 to move, that is, to adjust the position of the cutting blade 36. When cutting is not needed, the cutting blade 36 retracts.

[0036] The suction head 37, telescopic tube 38, and square block 34 are interconnected, thereby activating the air pump to adsorb dust and increase airflow near the cutting blade 36, thus achieving a certain degree of cooling. When the square block 34 descends, it will squeeze the pressure block 311, causing the pressure ring 312 to move downward. Finally, the flow port 3121 aligns with the connecting port 3131, allowing liquid to flow into the water outlet pipe 313 and finally be sprayed out through the water spray head 315, thus providing cooling and lubrication for the cutting fluid. When the pressure block 311 loses the pressure of the square block 34, it will be reset by the return spring 3122.
