Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe cutting technology, and in particular to a seamless steel pipe cutting head device. Background Technology

[0002] Seamless steel pipes are made from a single piece of metal and have no seams on their surface. After production, seamless steel pipes need to be cut to meet the standards for use.

[0003] A search revealed a Chinese patent for a seamless steel pipe cutting device (authorization announcement number CN214161570U), comprising a worktable with several support legs symmetrically mounted on its bottom. Two fixing plates, one and two fixed plates, are symmetrically mounted on the top surface of the worktable. Each fixing plate has a cylinder fixedly mounted inside it, and a fixing device is fixedly mounted on the inner side of each cylinder. A cutting device is fixedly mounted on one side of the top surface of the worktable. This patented technology, through two cylinders and several semi-arc rings, allows the device to clamp steel pipes of different diameters. The rollers inside the semi-arc rings allow the steel pipe to move along the vertical direction of the cut after being fixed, enabling the cutting wheel to cut the fixed steel pipe multiple times at different positions, thus avoiding the need for repeated disassembly and reassembly of the steel pipe.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the seamless steel pipe cutting device used above requires the clamping device to be loosened and then clamped again when adjusting the position of the pipe after it is clamped. The operation is complicated, and the debris after cutting is difficult to collect. Therefore, we propose a seamless steel pipe cutting device. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a seamless steel pipe cutting device.

[0006] The technical solution of this utility model is as follows: a seamless steel pipe cutting device includes a worktable, a groove is provided at the top of the worktable, and a fixing groove is provided inside the worktable on both sides of the groove.

[0007] By adopting the above technical solution, the piston rod of the cylinder can be extended and retracted to push the corresponding clamping parts to move. In this way, the two clamping parts can be used to clamp the seamless steel pipe. Under the rotation of the long screw, the entire pipe can be moved in the groove, thereby flexibly adjusting the cutting position of the seamless steel pipe.

[0008] In a preferred embodiment, a cleaning component is provided at the top of the workbench.

[0011] By adopting the above technical solution and using locking bolts, it is convenient for staff to install the cleaning strip on the two clamping parts.

[0012] In a preferred embodiment, the transmission component is slidably connected to the inner wall of the fixed groove.

[0013] By adopting the above technical solution, the transmission components can be limited, ensuring that the transmission components can be used stably.

[0015] By adopting the above technical solution, the cutting wheel can be pushed downward by the extension and retraction of the piston rod of the hydraulic cylinder, thereby adjusting the cutting height of the seamless steel pipe.

[0016] In a preferred embodiment, a drive motor a is fixedly mounted on the bottom of the mounting bracket, and a cutting wheel is fixedly connected to the output shaft of the drive motor a.

[0017] By adopting the above technical solution, the rotation of the output shaft of the drive motor a can drive the cutting wheel to rotate, thereby achieving the purpose of cutting seamless steel pipes.

[0018] In a preferred embodiment, two drive motors b are fixedly installed on the rear side of the worktable, and the output shafts of the drive motors b extend into the interior of the fixed groove and are fixedly connected to the long screw.

[0019] By adopting the above technical solution, the rotation of the output shaft of the drive motor b can drive the long screw to rotate, thereby realizing the transmission of power.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A seamless steel pipe cutting device includes a worktable 1. A groove is formed at the top of the worktable 1. Fixing slots 17 are formed inside the worktable 1 on both sides of the groove. Long screws 16 are rotatably connected inside each fixing slot 17. Transmission components 10 are threadedly connected to the outer sides of each long screw 16. Cylinders 13 are fixedly installed on the adjacent sides of the two transmission components 10. Clamping components 11 are fixedly connected to the piston rods of the cylinders 13. Telescopic strips 12 are fixedly connected to the outer sides of the clamping components 11 on both sides of the cylinders 13. The telescopic strips 12 are connected to the transmission components 1... The internal sliding connection of cylinder 13 allows the piston rod of cylinder 13 to extend and retract, which in turn moves the corresponding clamping member 11. Under the action of telescopic bar 12, the clamping member 11 remains relatively stable during adjustment. Thus, the two clamping members 11 can clamp the seamless steel pipe. Under the rotation of long screw 16, the entire pipe can move within the groove. This eliminates the need for workers to re-clamp and fix the seamless steel pipe after cutting a section. Through the above structure, the cutting position of the seamless steel pipe can be flexibly adjusted.

[0030] Specifically, a cleaning component is provided at the top of the workbench 1. The cleaning component includes a cutting groove 3 located inside the workbench 1 and below the groove. A carrier box 8 is fixedly connected to the bottom of the workbench 1 and below the cutting groove 3. The dust collection box 9 facilitates the entry of cutting debris into the dust collection box 9, and also facilitates the emptying and cleaning of the debris in the dust collection box 9. The dust collection box 9 is slidably connected inside the carrier box 8. The cleaning component also includes a cleaning strip 14 disposed between two clamping members 11. The use of locking bolts 15 makes it easy for the operator to install the cleaning strip 14 on the two clamping members 11. The movement of the transmission member 10 can drive the movement of the cleaning strip 14, thereby enabling the cleaning strip 14 to clean the debris in the groove uniformly. Two locking bolts 15 are provided inside the cleaning strip 14. The cleaning strip 14 is connected to the clamping member 11 by the locking bolts 15. The transmission member 10 is slidably connected to the inner wall of the fixed groove 17.

[0031] Specifically, a U-shaped frame 2 is fixedly connected to the top of the workbench 1, and a hydraulic cylinder 5 is fixedly installed on the top of the U-shaped frame 2. By extending and retracting the piston rod of the hydraulic cylinder 5, the cutting wheel 7 can be pushed downwards, thereby adjusting the cutting height of the seamless steel pipe. A mounting bracket 4 is fixedly connected to the piston rod of the hydraulic cylinder 5, and a drive motor a6 is fixedly installed at the bottom of the mounting bracket 4. By rotating the output shaft of the drive motor a6, the cutting wheel 7 can be driven to rotate, thereby achieving the purpose of cutting the seamless steel pipe. The cutting wheel 7 is fixedly connected to the output shaft of the drive motor a6. Two drive motors b18 are fixedly installed on the rear side of the workbench 1. By rotating the output shaft of the drive motor b18, the long screw 16 can be driven to rotate, thereby achieving the transmission of power. The output shaft of the drive motor b18 extends into the interior of the fixed groove 17 and is fixedly connected to the long screw 16.

[0032] Working principle: First, the operator can place the seamless steel pipe in the groove of the workbench 1. Then, the cylinder 13 is started by controlling the external controller. The extension and retraction of the piston rod of the cylinder 13 can push the corresponding clamping member 11 to move. In this way, the two clamping members 11 can achieve the purpose of clamping the seamless steel pipe. Then, the drive motor b18 is started. The rotation of the output shaft of the drive motor b18 can drive the long screw 16 to rotate, which can drive the transmission member 10 to move, and thus drive the entire pipe to slide in the groove. This allows the operator not to re-clamp and fix after cutting a section of seamless steel pipe. Finally, the operator can install the cleaning strip 14 on the two clamping members 11 by using the locking bolt 15. The movement of the transmission member 10 can drive the movement of the cleaning strip 14, which can sweep the debris in the groove into the dust collection box 9 for the operator to clean and wash.
