Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe cutting, and particularly to a stainless steel pipe cutting machine with segmented processing. Background Art

[0002] Stainless steel pipe cutting machines are special equipment for cutting stainless steel pipes. They usually have efficient, precise and stable cutting performance. The device adopts a segmented feeding system to divide the stainless steel pipe into multiple parts for cutting, and each part moves independently on the feeding system for precise cutting operations.

[0003] After retrieval, a Chinese patent with the publication number CN222520528U discloses a spiral steel pipe cutting device, including a cutting table. A cutting assembly is arranged on the top of the cutting table. Two second hydraulic cylinders are connected to the top of the cutting table. The output end of the second hydraulic cylinder is connected to a fixing frame. A fourth hydraulic cylinder is connected inside the fixing frame. The bottom of the fourth hydraulic cylinder is connected to an arc-shaped clamping plate. A U-shaped frame is connected to the bottom of the cutting table. The above solution uses a third hydraulic cylinder to push two grinding discs to the cut surfaces of two spiral steel pipes, presses the cut spiral steel pipes against the grinding discs, drives the second pulley to rotate by using a second motor, the second pulley drives the first pulley to rotate through a transmission belt, the first pulley drives the rotating shaft to rotate, and the rotating shaft drives the two grinding discs to rotate, so as to polish the cut surfaces of the spiral steel pipes, thereby reducing the transfer time and avoiding the problem of harming the staff during the transfer process. However, when the above solution is actually used, there are still the following deficiencies:

[0004] Although the steel pipe cutting device proposed by the above solution has the ability to polish the cut surfaces of the steel pipes after cutting, this function is limited to the cut surface part, and the outer edge and inner surface of the steel pipe fracture cannot be effectively polished. This limitation results in an unsatisfactory overall polishing effect of the steel pipe. Especially in the outer edge and inner surface parts of the fracture, there may be problems such as burrs, unevenness or residual cutting marks, which affect the subsequent processing quality of the steel pipe and the appearance and performance of the final product.

[0005] Therefore, it is necessary to design a stainless steel pipe cutting machine with segmented processing to solve the above problems. Summary of the Invention

[0023] The present invention has the following beneficial effects:

[0024] 1. By setting a positioning component to adjust the positions of the first grinding head, the second grinding head and the third grinding head, the three grinding heads can take turns to grind the cut end of the stainless steel pipe. This design brings significant benefits. First, it greatly improves the flexibility and efficiency of grinding, because different grinding heads can be accurately positioned to different parts of the stainless steel pipe as needed to achieve comprehensive and detailed grinding. Secondly, by setting the first grinding head, the second grinding head and the third grinding head of different shapes, this setting can not only effectively grind the cut surface of the stainless steel pipe, but also perform targeted grinding on the outer edge and inner surface of the stainless steel pipe, thereby completely removing the burrs on the cut surface and ensuring the best grinding effect. This comprehensive grinding strategy not only improves the surface quality of the stainless steel pipe, but also enhances its overall durability and aesthetics.

[0025] 2. By moving the moving seat, using the meshing effect of the second gear and the second rack, the second rotating shaft is driven to rotate, and then the 180° flipping of the mounting plate and the fixing plate is realized, ensuring that the first grinding head, the second grinding head and the third grinding head can accurately align with the position of the bristles. Subsequently, the continuous movement of the moving seat causes the grinding head to contact the bristles. At this time, the motor is started to drive the grinding head to rotate, and the bristles then brush the grinding head, effectively brushing off the debris attached thereto. This process not only realizes the automatic cleaning of the grinding head, but also ensures the thoroughness and efficiency of the cleaning, avoiding the negative impact of debris accumulation on the grinding effect and subsequent work. In addition, the design of this cleaning unit also reflects automation and intelligence, greatly reducing the labor intensity of the staff and improving the overall work efficiency and grinding quality;

[0026] 3. Through the precise movement of the lifting plate and the air extraction action of the driving member, the secondary cleaning of the bristles above the cleaning plate is realized. During the process of the back plate resetting and moving away from the cleaning plate, the driving member extracts the gas in the executing member, causing the third rack to move downward and reset. This action not only drives the reverse rotation of the sixth gear, but also causes the winding wheel to release the connecting rope. As the connecting rope is released, the lifting plate naturally descends under the action of gravity, and the comb teeth thereon cleverly scrape off the debris attached to the bristles, ensuring the cleanliness of the bristles. This design not only enhances the self-maintenance ability of the cleaning unit, but also ensures the effect of the bristles when cleaning the first grinding head, the second grinding head and the third grinding head subsequently, avoiding the influence of debris residue on the grinding quality and efficiency;

[0027] 4. By driving the fourth gear to rotate by the motor, the fifth gear and the third rotating shaft meshing therewith are driven to rotate, so that the suction fan starts to work. The efficient rotation of the suction fan generates a strong suction force, and effectively extracts the dust generated during the grinding process through the suction holes on the suction pipe. These dusts are quickly sucked into the dust collection box under the action of the suction fan and are finally intercepted by the filter element, effectively preventing the escape of dust. This innovation not only significantly improves the working environment, reduces the risk of operators inhaling harmful dust, but also enhances the overall cleanliness and safety of the grinding operation.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0045] Refer to Figures 1 - 15, A segmented stainless steel pipe cutting machine, comprising an automated intelligent pipe cutting machine 1, a moving unit, a grinding unit and a cleaning unit. An feeding module 101, a supporting fixture 102 and a cutting module 103 are arranged on the automated intelligent pipe cutting machine 1. When the proposed segmented stainless steel pipe cutting machine is in use, the stainless steel pipe to be cut is clamped on the feeding module 101. The stainless steel pipe passes through the supporting fixture 102 and the pipe fixture 23. The feeding module 101 is used for feeding the stainless steel pipe. The supporting fixture 102 is used for supporting the stainless steel pipe. The cutting module 103 is located between the supporting fixture 102 and the pipe fixture 23 and is used for cutting the stainless steel pipe. After the cutting module 103 cuts off the stainless steel pipe, the cut part is clamped by the pipe fixture 23. In addition, a grinding unit and a cleaning unit are arranged on the automated intelligent pipe cutting machine 1. The grinding unit is arranged between the pipe fixture 23 and the cleaning unit, and the cleaning unit is arranged at the tail end of the automated intelligent pipe cutting machine 1. The grinding unit is used for grinding the cut end of the stainless steel pipe, and the cleaning unit is used for cleaning the first grinding head 42, the second grinding head 43 and the third grinding head 44 in the grinding unit to remove the debris attached to the surfaces of the first grinding head 42, the second grinding head 43 and the third grinding head 44. It should be noted that the specific structures and working principles of the feeding module 101, the supporting fixture 102 and the cutting module 103 are prior arts, and the implementation methods adopt conventional means, which are not shown in the figure and will not be elaborated here;

[0046] The moving unit is arranged on the automated intelligent pipe cutting machine 1 and is used for moving the cut steel pipe. The moving unit includes a bottom plate 21, a top plate 22, a pipe fixture 23, a first rack 26 and a servo cylinder 27. The bottom plate 21 is slidably assembled on the automated intelligent pipe cutting machine 1. The top plate 22 is arranged above the bottom plate 21. The pipe fixture 23 is installed on the top surface of the top plate 22. A first rotating shaft 24 is arranged between the bottom plate 21 and the top plate 22. One end of the first rotating shaft 24 is rotatably connected to the bottom plate 21, and the other end is fixedly connected to the top plate 22.

The first rack 26 is fixed on the telescopic end of the servo cylinder 27, and the first rack 26 meshes with the first gear 25;

[0047] For the mobile unit, it is used to clamp the cut stainless steel pipe. After the stainless steel pipe is cut, the mobile unit moves on the automatic intelligent pipe cutting machine 1 and drives the stainless steel pipe to move, so that the pipe orifice position of the stainless steel pipe moves to the grinding unit, facilitating the grinding unit to grind the pipe orifice of the stainless steel pipe. The mobile unit also has the function of flipping the stainless steel pipe, enabling the grinding unit to grind both ends of the stainless steel pipe. Specifically, when the stainless steel pipe needs to be flipped, the servo cylinder 27 is activated and drives the first rack 26 to move. When the first rack 26 moves, it drives the first gear 25 to rotate, causing the first rotating shaft 24 to rotate. The top plate 22 connected to the first rotating shaft 24 rotates accordingly, so that the pipe fixture 23 drives the stainless steel pipe to rotate, realizing the automatic flipping function of the stainless steel pipe;

[0048] The grinding unit includes a bracket assembly, a grinding assembly, and a positioning assembly. The grinding assembly includes a back plate 41, a first grinding head 42, a second grinding head 43, and a third grinding head 44. The first grinding head 42, the second grinding head 43, and the third grinding head 44 are all arranged on the back plate 41. The first grinding head 42, the second grinding head 43, and the third grinding head 44 are circumferentially arrayed around the center position of the back plate 41. The surface of the first grinding head 42 is flat. The second grinding head 43 is provided with grinding grooves. The third grinding head 44 has a frustum-shaped structure. The bracket assembly includes a moving seat 31, a mounting plate 32, a fixing plate 35, a connecting frame 36, and a second rack 37. The moving seat 31 is slidably assembled on the automatic intelligent pipe cutting machine 1. The mounting plate 32 is arranged above the moving seat 31. The fixing plate 35 is fixed to the top surface of the mounting plate 32. A second rotating shaft 33 is provided between the moving seat 31 and the mounting plate 32. One end of the second rotating shaft 33 is rotatably connected to the moving seat 31, and the other end is fixed to the mounting plate 32. A second gear 34 is fixedly sleeved on the second rotating shaft 33. One end of the connecting frame 36 is fixed to the automatic intelligent pipe cutting machine 1, and the other end is fixed to the second rack 37. The second rack 37 is arranged opposite to the second gear 34;

[0049] The grinding assembly further includes three shaft rods 45, a bracket 47 and a motor 48. The three shaft rods 45 are all rotatably assembled on the back plate 41. The three shaft rods 45 are respectively connected to the first grinding head 42, the second grinding head 43 and the third grinding head 44. The bracket 47 is fixed on the side of the back plate 41. The motor 48 is installed on the bracket 47. Third gears 46 are fixedly sleeved on the three shaft rods 45. A fourth gear 49 is fixedly sleeved on the output shaft of the motor 48. The three third gears 46 are all meshed with the fourth gear 49. The positioning assembly includes an outer cylinder 51, an inner rod 52, a positioning plate 53, three positioning rods 54, three positioning ports 55 and a rotating ring 56. The outer cylinder 51 is fixed on the side of the bracket 47, and one end of the outer cylinder 51 is open. The outer cylinder 51 passes through the fixing plate 35 and is rotatably connected to the fixing plate 35. The inner rod 52 is movably inserted into the outer cylinder 51. The inner surface of the outer cylinder 51 is in contact with the outer surface of the inner rod 52. One end of the inner rod 52 extends to the outside of the outer cylinder 51. The positioning plate 53 is fixedly sleeved on one end of the inner rod 52 located outside the outer cylinder 51. The three positioning rods 54 are all fixed on the side of the positioning plate 53. The three positioning ports 55 are all opened on the fixing plate 35. The three positioning rods 54 are respectively arranged opposite to the three positioning ports 55. The rotating ring 56 is rotatably installed on the side of the fixing plate 35. The positioning plate 53 and the rotating ring 56 are connected by a connecting spring 57;

[0050] For the grinding unit, the motor 48 serves as the power source. When the motor 48 operates, it drives the fourth gear 49 to rotate. The three third gears 46 meshed with the fourth gear 49 rotate synchronously, causing the three shaft rods 45 to rotate. When the three shaft rods 45 rotate, they can drive the first grinding head 42, the second grinding head 43 and the third grinding head 44 to rotate. The surface of the first grinding head 42 is flat and is used to grind the cut surface of the stainless steel pipe. The second grinding head 43 is provided with a grinding groove for grinding the outer edge of the cut opening of the stainless steel pipe. In the direction close to the back plate 41, the notch of the grinding groove gradually decreases, which enables the grinding groove to be applicable to stainless steel pipes of different sizes. The third grinding head 44 has a frustum-shaped structure and is used to grind the inner surface of the cut opening of the stainless steel pipe, which enables the third grinding head 44 to be applicable to stainless steel pipes of different sizes to ensure the versatility of the grinding unit. In the initial state, the first grinding head 42 is arranged opposite to the pipe fixture 23. Under the movement of the moving unit, the pipe orifice of the stainless steel pipe first comes into contact with the first grinding head 42, and the first grinding head 42 grinds the pipe orifice;

[0051] After the first grinding head 42 grinds the pipe orifice for a period of time, the moving unit drives the stainless steel pipe to move away from the back plate 41 until the stainless steel pipe is separated from the first grinding head 42. Then, the operator can adjust the angle of the back plate 41 through the positioning component until the second grinding head 43 rotates to a position facing the pipe fixture 23. Specifically, the operator first pulls the inner rod 52. When the inner rod 52 moves, it drives the positioning plate 53 to move, and the three positioning rods 54 on the positioning plate 53 move accordingly until the three positioning rods 54 move out of the three positioning ports 55 respectively. At this time, the three positioning rods 54 and the three positioning ports 55 no longer provide limits to the inner rod 52 and the outer cylinder 51. Then, the operator rotates the back plate 41, causing the back plate 41 to drive the first grinding head 42, the second grinding head 43, and the third grinding head 44 until the second grinding head 43 rotates to a position facing the pipe fixture 23. When the back plate 41 rotates, it can drive the support 47 to rotate, and the outer cylinder 51 connected to the support 47 rotates accordingly, causing the inner rod 52 and the positioning plate 53 to rotate synchronously. When the first grinding head 42, the second grinding head 43, and the third grinding head 44 rotate to the in-place position, the three positioning rods 54 just face the three positioning ports 55 again. At this time, the operator can release the inner rod 52, causing the positioning plate 53 to reset under the action of the connecting spring 57 until the three positioning rods 54 are inserted into the three positioning ports 55 again. In this case, the three positioning rods 54 and the three positioning ports 55 provide limits to the back plate 41, and the positions of the back plate 41, the first grinding head 42, the second grinding head 43, and the third grinding head 44 will be fixed. Based on the above process, the operator can adjust the positions of the first grinding head 42, the second grinding head 43, and the third grinding head 44 through the positioning component, so that the first grinding head 42, the second grinding head 43, and the third grinding head 44 take turns to grind the cut-off port of the stainless steel pipe. By setting the first grinding head 42, the second grinding head 43, and the third grinding head 44 with different shapes, the grinding unit can not only grind the cut-off surface of the stainless steel pipe, but also grind the outer edge and the inner surface of the stainless steel pipe, thoroughly removing the burrs on the cut-off surface of the stainless steel pipe to ensure the grinding effect on the stainless steel pipe;

[0052] A dust collection assembly is provided on the fixed plate 35, and the dust collection assembly includes an air suction cylinder 61, a third rotating shaft 62, an air suction fan 63, a fifth gear 64, a dust collection box 65 and a dust collection pipe 68. The third rotating shaft 62 is rotatably mounted on the air suction cylinder 61, the air suction fan 63 is fixedly sleeved on the third rotating shaft 62, and the air suction fan 63 is located inside the air suction cylinder 61, the fifth gear 64 is fixedly sleeved on the third rotating shaft 62, and the fifth gear 64 and the fourth gear 49 are meshed with each other, the dust collection box 65 is arranged on the bracket 47, and the dust collection box 65 has a built-in filter element 66, the air suction cylinder 61 and the dust collection box 65 are connected through a connecting pipe 67, the dust collection pipe 68 is fixed at the center position of the side of the back plate 41, and a plurality of dust suction ports are provided on the dust collection pipe 68, and the dust collection box 65 and the dust collection pipe 68 are connected through a connecting pipe 69;

[0053] The grinding unit proposed in the present invention also has the function of absorbing dust. Specifically, when the fourth gear 49 rotates under the driving action of the motor 48, the fourth gear 49 can drive the fifth gear 64 meshing therewith to rotate, so that the fifth gear 64 drives the third rotating shaft 62 to rotate, and the suction fan 63 connected to the third rotating shaft 62 rotates accordingly. When the suction fan 63 rotates, it performs an exhaust action, so that the several dust suction holes on the dust suction pipe 68 can extract the dust scattered during the grinding process. Under the suction action of the suction fan 63, the dust is sucked into the dust collecting box 65 and finally intercepted by the filter element 66. This design can prevent the dust from flying around.

The winding wheel 81 is installed at the top of the side plate 71. One end of the connecting rope 82 is connected to the winding wheel 81, and the other end is connected to the lifting plate 74. The sixth gear 83 is fixedly sleeved on the axle of the winding wheel 81. The actuator 85 is arranged on the side of the side plate 71, the driving member 86 is arranged on the side of the automatic intelligent pipe cutting machine 1, and the pushing member is arranged at one end of the moving seat 31. The pushing member is arranged opposite to the driving member 86. The actuator 85 and the driving member 86 are connected and communicated through an air supply pipe 87. The third rack 84 is connected to the actuator 85, and the third gear 46 meshes with the sixth gear 83. Both the actuator 85 and the driving member 86 include a sealing cylinder and a push rod. The push rod is connected to the sealing cylinder in a sealed and sliding manner, and one end of the push rod extends to the outside of the sealing cylinder. The sealing cylinder and the push rod are connected by a spring. The push rod in the actuator 85 is connected to the third rack 84.

[0056] The pushing member includes a fixed seat 88, a slot 89 and a push block 810. The fixed seat 88 is fixed at one end of the moving seat 31. The slot 89 is formed in the bottom surface of the fixed seat 88. The push block 810 is slidably arranged in the slot 89. Two inclined surfaces with opposite inclination directions are arranged on the push block 810. The push block 810 is connected to the top of the slot 89 by a return spring 811. Both inclined surfaces of the push block 810 are located outside the slot 89 and are arranged opposite to the push rod in the driving member 86.

[0057] When the pipe orifice is polished, debris will inevitably adhere to the surfaces of the first polishing head 42, the second polishing head 43 and the third polishing head 44. The adhesion of the debris will not only reduce the polishing efficiency of the polishing head, because the adherents will prevent the direct contact between the polishing head and the pipe orifice surface, thus affecting the uniformity and precision of polishing. At the same time, these debris may also cause scratches or damages during the subsequent polishing process, further affecting the polishing quality. To avoid this situation, the present invention designs a cleaning unit for cleaning the debris adhering to the first polishing head 42, the second polishing head 43 and the third polishing head 44. Specifically, when it is necessary to clean the first polishing head 42, the second polishing head 43 and the third polishing head 44, the moving seat 31 moves on the automatic intelligent pipe cutting machine 1, so that the whole polishing unit moves. During this process, the second gear 34 will engage with the second rack 37 and rotate under the action of the second rack 37. When the second rack 37 rotates, it drives the second rotating shaft 33 to rotate, so that the mounting plate 32 and the fixing plate 35 are turned over. When the second gear 34 is separated from the second rack 37, the second rotating shaft 33 just rotates 180°, so that the mounting plate 32 and the fixing plate 35 just turn over 180°. In this case, the first polishing head 42, the second polishing head 43 and the third polishing head 44 can rotate to the position facing the brush hair 73. After the turning-over is completed, the moving seat 31 continues to move until the first polishing head 42, the second polishing head 43 and the third polishing head 44 contact the brush hair 73. When the first polishing head 42, the second polishing head 43 and the third polishing head 44 contact the brush hair 73, the moving seat 31 stops moving. Subsequently, the motor 48 is started and drives the first polishing head 42, the second polishing head 43 and the third polishing head 44 to rotate. When the first polishing head 42, the second polishing head 43 and the third polishing head 44 rotate, the brush hair 73 will brush the first polishing head 42, the second polishing head 43 and the third polishing head 44 and brush off the debris adhering thereto, playing a role in cleaning the first polishing head 42, the second polishing head 43 and the third polishing head 44;

[0058] During the process of the moving seat 31 approaching the cleaning plate 72, the pushing block 810 is extruded by the push rod in the driving member 86. During this process, the elastic force of the spring in the driving member 86 cannot overcome the elastic force of the return spring 811 above the pushing block 810, which enables the pushing block 810 to push the push rod in the driving member 86 to move. When the push rod in the driving member 86 moves, it can press the gas in the sealing cylinder in the driving member 86 into the sealing cylinder in the actuator 85 through the air supply pipe 87, causing the gas to push the push rod in the actuator 85 to move, and finally causing the third rack 84 to move. Under the combined action of the driving member 86 and the actuator 85, during the process of the moving seat 31 approaching the cleaning plate 72, the third rack 84 will move upward and drive the sixth gear 83 to rotate. When the sixth gear 83 rotates, it can drive the winding wheel 81 to rotate, causing the winding wheel 81 to wind up the connecting rope 82. When the connecting rope 82 is wound up, the connecting rope 82 can pull up the lifting plate 74, causing the lifting plate 74 to move upward. Based on the above process, after the back plate 41 is flipped, the lifting plate 74 just moves above the cleaning plate 72. After the cleaning work is completed, the back plate 41 is reset under the action of the moving seat 31 and moves in the direction away from the cleaning plate 72. During this process, the driving member 86 performs a pumping action and extracts the gas in the actuator 85, causing the third rack 84 to move downward and reset. When the third rack 84 resets, it drives the sixth gear 83 to rotate in the reverse direction, causing the winding wheel 81 to release the connecting rope 82. When the connecting rope 82 is released, the lifting plate 74 descends under the action of gravity. During this process, several comb teeth 75 on the lifting plate 74 can scrape off the debris attached to the brush bristles 73, playing a role in cleaning the brush bristles 73 to ensure the subsequent cleaning effect of the brush bristles 73 on the first grinding head 42, the second grinding head 43, and the third grinding head 44;

[0059] It should be noted that guide blocks are fixed at both ends of the lifting plate 74, and two guide rods are fixed on the automatic intelligent pipe cutting machine 1. The two guide blocks are respectively slidably sleeved on the two guide rods to provide limits for the up and down movement of the lifting plate 74. In addition, two inclined surfaces are provided on the pushing block 810. When the push rod in the driving member 86 moves to the limit position and cannot continue to move, the push rod will squeeze the inclined surface on the pushing block 810, causing the pushing block 810 to move upward. This design can avoid the situation of movement interference between the pushing block 810 and the push rod in the driving member 86. It should be pointed out that the moving function of the moving unit and the moving seat 31 is proposed as an existing technology and is not shown in the figure, nor will it be elaborated here. Preferably, the moving unit can be realized by the cooperation of a motor, gears, and a rack, or can be driven by a cylinder.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
