Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe production technology, specifically a cutter for processing seamless steel pipes. Background Technology

[0002] Cutting is a crucial step in the processing of seamless steel pipes. Seamless steel pipes are widely used in many fields such as construction, machinery manufacturing, and petrochemicals. Different application scenarios have different requirements for the length of seamless steel pipes, so it is often necessary to cut seamless steel pipes into multiple sections to meet actual usage needs.

[0003] Existing seamless steel pipe cutting tools perform single-point cutting after the seamless steel pipe is clamped. Operators need to perform multiple clamping and cutting operations on the seamless steel pipe, which greatly reduces cutting efficiency and increases labor and time costs. Utility Model Content

[0004] The purpose of this utility model is to provide a cutter for seamless steel pipe processing, so as to solve the problem mentioned in the background art that when the existing cutter for seamless steel pipe processing cuts seamless steel pipe into multiple segments, multiple clamping and cutting operations are required, which greatly reduces the cutting efficiency and increases labor and time costs.

The piston end of the lifting cylinder is fixedly connected to the bottom of the lifting bracket. A motor is fixedly connected to the surface of the lifting bracket. A cutting rotor is fixedly connected to the output shaft of the motor. A cutting disc is slidably connected to the surface of the cutting rotor. A limit ring is fixedly connected to one side of the cutting disc. A bolt is perforated and connected to the surface of the limit ring. A limit nut is threaded onto the surface of the bolt.

[0006] Preferably, the dual-axis clamping cylinder is provided with two sets of piston rods. The dual-axis clamping cylinder pushes the moving rod to slide in opposite directions on the cutting table through the two sets of piston rods. A guide hole is opened on the surface of the cutting table, and the moving rod slides on the guide hole of the cutting table in an "L" shape.

[0007] Preferably, multiple sets of clamping blocks are provided on one side of the moving frame and are arranged linearly and evenly. The moving frame drives the multiple sets of clamping blocks to slide synchronously through the connecting column.

[0008] Preferably, the clamping block slides on the moving frame via the connecting post and the guide rod, the stud slides along the connecting post on one side of the moving frame, and the locking nut engages with the stud to restrict the connecting post from continuing to slide.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This cutter uses a dual-axis clamping cylinder to drive the moving rod, which in turn moves the moving frame and multiple clamping blocks synchronously. This allows for stable clamping of seamless steel pipes at multiple positions. Simultaneously, the motor drives the cutting rotor to rotate, causing multiple cutting discs to rotate synchronously. In conjunction with the lifting cylinder driving the lifting bracket, multiple cutting discs can simultaneously cut the seamless steel pipe, avoiding the cumbersome operations required for traditional single-point multiple cutting, reducing the number of clamping and cutting operations, and greatly improving cutting efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A cutter for processing seamless steel pipes includes a cutting table 1, a clamping mechanism on the surface of the cutting table 1, and a cutting mechanism on the surface of the cutting table 1. The clamping mechanism includes a dual-axis clamping cylinder 2, which is fixedly connected to the surface of the cutting table 1. A moving rod 21 is fixedly connected to the piston end of the dual-axis clamping cylinder 2. A moving frame 22 is fixedly connected to the surface of the moving rod 21. A guide rod 23 is fixedly connected to the surface of the moving frame 22. A connecting post 24 is slidably connected to the surface of the guide rod 23. A clamping block 25 is fixedly connected to the surface of the connecting post 24. A stud 26 is fixedly connected to the surface of the connecting post 24. A locking nut 27 is threaded onto the surface of the stud 26. The cutting mechanism includes a telescopic rod 3, which is fixedly connected to the surface of the cutting table 1. A lifting cylinder 32 is fixedly connected to the telescopic end of the telescopic rod 3. The piston end of the lifting cylinder 32 is fixedly connected to the bottom of a lifting bracket 31. A motor 33 is fixedly connected to the upper part of the cutting mechanism. A cutting rod 34 is fixedly connected to the output shaft of the motor 33. A cutting disc 35 is slidably connected to the surface of the cutting rod 34. A limit ring 36 is fixedly connected to one side of the cutting disc 35. A bolt 37 is perforated and connected to the surface of the limit ring 36. A limit nut 38 is threaded and connected to the surface of the bolt 37. The cutting mechanism clamps the seamless steel pipe at multiple positions through the clamping mechanism. In conjunction with the multiple cutting discs 35 of the cutting mechanism, the seamless steel pipe is cut simultaneously. The clamping mechanism, with its multiple clamping, enables the multiple cutting discs 35 to cut the seamless steel pipe stably, thus eliminating the need for multiple single-point cuts and greatly improving the cutting efficiency. Furthermore, the clamping block 25 of the clamping mechanism and the cutting disc 35 of the cutting mechanism can be adjusted in position, thereby adjusting the cutting position. The adjustment of the position of the clamping block 25 avoids conflict with the cutting position of the cutting disc 35. By adjusting these positions, the flexibility and adaptability of the cutter are greatly improved.

[0024] Furthermore, the dual-axis clamping cylinder 2 is equipped with two sets of piston rods. The dual-axis clamping cylinder 2 pushes the moving rod 21 to slide in opposite directions on the cutting table 1 through the two sets of piston rods. A guide hole is opened on the surface of the cutting table 1. The moving rod 21 slides in an "L" shape on the guide hole of the cutting table 1. The guide hole of the cutting table 1 ensures the stability of the moving rod 21 during the sliding process.

[0025] Furthermore, multiple sets of clamping blocks 25 are provided on one side of the moving frame 22 and are arranged linearly and evenly. The moving frame 22 drives the multiple sets of clamping blocks 25 to slide synchronously through the connecting column 24, so that the multiple sets of clamping blocks 25 clamp the seamless steel pipe synchronously. The number of clamping blocks 25 is one more than the number of cutting discs 35, so that each set of seamless steel pipes to be cut is firmly clamped and fixed by the clamping blocks 25. When the cutting disc 35 cuts the seamless steel pipe, the clamping blocks 25 can effectively prevent the steel pipe from shaking or displacing during the cutting process, ensuring the stability of the cutting disc 35.

[0026] Furthermore, the clamping block 25 slides on the moving frame 22 via the connecting post 24 and the guide rod 23. The stud 26 slides on one side of the moving frame 22 following the connecting post 24. The locking nut 27 engages with the stud 26 to restrict the connecting post 24 from continuing to slide, thereby restricting the sliding of the clamping block 25. This allows the position of the clamping block 25 on the moving frame 22 to be changed. The adjustable structural design enables the clamping block 25 to adapt to different cutting requirements and avoids conflict with the cutting position of the cutting disc 35.

[0027] Furthermore, the lifting support 31 is in the shape of a "U". The lifting support 31 is horizontally raised and lowered on the cutting table 1 by multiple sets of telescopic rods 3. The lifting cylinder 32 drives the cutting table 1 to be horizontally raised and lowered through the piston rod. Thus, the lifting support 31 drives the cutting disc 35 to be raised and lowered. With the rotation of the cutting disc 35, the seamless steel pipe is cut.

[0028] Furthermore, multiple sets of cutting discs 35 are arranged linearly and evenly on the surface of the cutting rotor 34. A protrusion is provided on the surface of the cutting rotor 34. The motor 33 drives the cutting rotor 34 to rotate through the output shaft. The cutting rotor 34, in conjunction with the protrusion, drives multiple sets of cutting discs 35 to rotate synchronously. The cutting discs 35 and the limiting ring 36 are provided with grooves corresponding to the protrusion of the cutting rotor 34, so that the limiting ring 36 and the limiting ring 36 rotate synchronously with the cutting rotor 34.

[0029] Furthermore, multiple sets of limiting holes are formed on the surface of the cutting rod 34, and they are arranged linearly and evenly. The limiting ring 36 slides synchronously on the cutting rod 34 along with the cutting disc 35. A circular hole is formed on the surface of the limiting ring 36. The bolt 37 passes through both the circular hole of the limiting ring 36 and the limiting hole of the cutting rod 34, thereby limiting the position of the limiting ring 36 on the cutting rod 34, and thus limiting the position of the cutting disc 35 on the cutting rod 34. With the locking of the upper limit nut 38 and the bolt 37 on the limiting ring 36, the position of the cutting disc 35 on the cutting rod 34 can be adjusted, thereby changing the cutting position of the cutting disc 35.

[0030] Working principle: When the dual-axis clamping cylinder 2 is activated, its two sets of piston rods push the moving rod 21 to slide within the guide hole of the cutting table 1. The moving rod 21 drives the moving frame 22 to move. The moving frame 22 drives multiple sets of clamping blocks 25 to slide synchronously through the connecting column 24, realizing synchronous clamping of the seamless steel pipe at multiple positions. At the same time, the motor 33 is activated, and its output shaft drives the cutting rotor 34 to rotate. The protrusion on the cutting rotor 34 drives multiple sets of linearly and evenly arranged cutting discs 35 to rotate synchronously. The lifting cylinder 32 drives the lifting bracket 31 to descend, so that the cutting discs 35 descend to the position of contacting the seamless steel pipe. Multiple sets of cutting discs 35 cut the seamless steel pipe at the same time. This multi-position synchronous cutting method eliminates the need for single-point multiple cutting of the seamless steel pipe, greatly improving cutting efficiency, reducing the number of manual operations, and reducing labor and time costs.

[0031] The clamping block 25 of the clamping mechanism and the cutting disc 35 of the cutting mechanism can be adjusted in position, thereby achieving flexible adjustment of the cutting position. For the clamping block 25, when it is necessary to adjust its position, first loosen the locking nut 27, and the connecting column 24 can slide freely on the guide rod 23, driving the clamping block 25 to slide to the appropriate position on the moving frame 22. Then tighten the locking nut 27, and the stud 26 cooperates with the locking nut 27 to restrict the sliding of the connecting column 24 and fix the position of the clamping block 25. For the cutting disc 35, first loosen the limiting nut 38 and pull out the bolt. 37. The limiting ring 36 can drive the cutting disc 35 to slide on the cutting rotating rod 34. When the cutting disc 35 reaches the predetermined position, the circular hole of the limiting ring 36 is aligned with the corresponding limiting hole of the cutting rotating rod 34. The bolt 37 is inserted and the limiting nut 38 is tightened to limit the position of the cutting disc 35. By adjusting the position of the clamping block 25 and the cutting disc 35, the cutting position can be changed according to different cutting requirements. Moreover, the adjustment of the position of the clamping block (25) can avoid conflict with the cutting position of the cutting disc (35), which greatly improves the flexibility and adaptability of the cutter.
