Description

Technical Field

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

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

[0003] After searching, the Chinese patent with the announcement number CN222520528U discloses a spiral steel pipe cutting device, including a cutting table, a cutting assembly is provided 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 fixed frame, a fourth hydraulic cylinder is connected to the fixed frame, the bottom of the fourth hydraulic cylinder is connected to an arc-shaped clamping plate, and the bottom of the cutting table is connected to a U-shaped frame. The above scheme uses the third hydraulic cylinder to push the two grinding discs to be located at the incision of the two spiral steel pipes, and the cut spiral steel pipe is pressed against the grinding disc. By using the second motor to drive the second pulley to rotate, the second pulley drives the first pulley to rotate through the transmission belt, the first pulley drives the rotating shaft to rotate, and the rotating shaft drives the two grinding discs to rotate, so that the cut surface of the spiral steel pipe can be polished, thereby reducing the transportation time and avoiding the problem of injury to the staff during the transportation process. However, the above scheme still has the following shortcomings when used in practice:

[0004] Although the steel pipe cutting device proposed in the above scheme has the ability to grind the cross-section of the steel pipe after cutting, this function is limited to the cross-section part, and the outer edge and inner surface of the steel pipe fracture cannot be effectively polished. This limitation leads to an unsatisfactory overall grinding effect of the steel pipe, especially on the outer edge and inner surface of the fracture, which may have burrs, unevenness or residual cutting marks, thereby affecting 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, achieving 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 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 movable base and utilizing the meshing action of the second gear and the second rack, the second rotating shaft is driven to rotate, thereby realizing a 180° flip of the mounting plate and the fixed plate, ensuring that the first grinding head, the second grinding head and the third grinding head can be accurately aligned with the brush position. Subsequently, the continued movement of the movable base causes the grinding head to contact the brush. At this time, the motor starts, driving the grinding head to rotate, and the brush brushes the grinding head, effectively brushing off the debris attached to it. 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 the cleaning unit also embodies 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 pumping action of the driving part, the secondary cleaning of the bristles above the cleaning plate is achieved. When the back plate is reset and away from the cleaning plate, the driving part extracts the gas in the actuator, prompting the third rack to move down 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. The comb tooth design on it cleverly scrapes 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 effectiveness of the bristles in subsequent cleaning of the first, second and third grinding heads, avoiding the impact of residual debris on the grinding quality and efficiency.

[0027] 4. The motor drives the fourth gear to rotate, which in turn drives the meshing fifth gear and the third shaft to rotate, causing the suction fan to start working. The efficient rotation of the suction fan generates strong suction, which effectively extracts the dust generated during the grinding process through the dust suction holes on the dust suction pipe. Under the action of the suction fan, this dust is quickly sucked into the dust collection box and eventually intercepted by the filter element, effectively preventing the dust from escaping. This innovation not only significantly improves the working environment and reduces the risk of operators inhaling harmful dust, but also improves the overall cleanliness and safety of the grinding operation.

The outer cylinder 51 is fixed to the side of the bracket 47. , and one end of the outer cylinder 51 is open, the outer cylinder 51 passes through the fixed plate 35 and is rotatably connected to the fixed plate 35, the inner rod 52 is movably inserted into the outer cylinder 51, the inner surface of the outer cylinder 51 and the outer surface of the inner rod 52 fit each other, one end of the inner rod 52 extends to the outside of the outer cylinder 51, the positioning plate 53 is fixedly sleeved on the 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 holes 55 are all opened on the fixed plate 35, the three positioning rods 54 are respectively arranged opposite to the three positioning holes 55, the rotating ring 56 is rotatably installed on the side of the fixed plate 35, and 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 a power source. When the motor 48 is running, it drives the fourth gear 49 to rotate, and the three third gears 46 meshing with the fourth gear 49 rotate synchronously, so that the three shafts 45 rotate. When the three shafts 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 end of the stainless steel pipe. 1, the notch of the grinding groove gradually decreases, which makes the grinding groove applicable to stainless steel pipes of different sizes. The third grinding head 44 is a truncated cone structure and is used to grind the inner surface of the cut end of the stainless steel pipe. This makes the third grinding head 44 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 clamp 23. Under the movement of the moving unit, the pipe end of the stainless steel pipe first contacts the first grinding head 42, and the first grinding head 42 grinds the pipe end.

[0051] After the first grinding head 42 grinds the pipe opening 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 staff can adjust the angle of the back plate 41 through the positioning assembly until the second grinding head 43 is rotated to a position facing the pipe clamp 23. Specifically, the staff 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 are respectively moved from the three positioning rods 54 to the three positioning rods 54. The inner rod 52 and the outer tube 51 are moved out of the opening 55. At this time, the three positioning rods 54 and the three positioning openings 55 no longer provide a limit for the inner rod 52 and the outer tube 51. Then the staff rotates the back plate 41, so that the back plate 41 drives 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 clamp 23. When the back plate 41 rotates, it can drive the bracket 47 to rotate, and the outer tube 51 connected to the bracket 47 rotates accordingly, so that the inner rod 52 and the positioning plate 53 also rotate synchronously. When the first grinding head 42, the second grinding head 43 and the third grinding head 44 are rotated, the inner rod 52 and the positioning plate 53 also rotate synchronously. When the first grinding head 43 and the third grinding head 44 are rotated into place, the three positioning rods 54 are just opposite the three positioning holes 55 again. At this time, the staff can loosen the inner rod 52, so that the positioning plate 53 is reset under the action of the connecting spring 57 until the three positioning rods 54 are inserted into the three positioning holes 55 again. In this case, the three positioning rods 54 and the three positioning holes 55 provide limit for 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 staff can The positioning assembly adjusts the positions of the first grinding head 42, the second grinding head 43 and the third grinding head 44, so that the first grinding head 42, the second grinding head 43 and the third grinding head 44 take turns to grind the cut end of the stainless steel pipe. By setting the first grinding head 42, the second grinding head 43 and the third grinding head 44 of different shapes, the grinding unit can not only grind the cut surface of the stainless steel pipe, but also grind the outer edge and the inner surface of the stainless steel pipe, and completely remove the burrs on the cut surface of the stainless steel pipe, so as to ensure the grinding effect of the stainless steel pipe;

The sixth gear 83 is fixedly sleeved on the axle of the winding wheel 81. The executive member 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. The pushing member is arranged on one side of the movable seat 31. The pusher is arranged opposite to the driving member 86, and the actuator 85 and the driving member 86 are connected by the air supply pipe 87. The third rack 84 is connected to the actuator 85, and the third gear 46 and the sixth gear 83 are meshed with each other. The actuator 85 and the driving member 86 both include a sealing cylinder and a push rod. The push rod is sealingly and slidably connected inside the sealing cylinder, 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 push member includes a fixed seat 88, a slot 89, and a push block 810. The fixed seat 88 is fixed to one end of the movable seat 31. The slot 89 is provided on the bottom surface of the fixed seat 88. The push block 810 is slidably disposed in the slot 89. The push block 810 is provided with two inclined surfaces inclined in opposite directions. The push block 810 is connected to the top of the slot 89 by a return spring 811. The two inclined surfaces of the push block 810 are both located outside the slot 89 and are directly opposite to the push rod in the driving member 86.

[0057] When the pipe mouth is being 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 attachments will hinder the direct contact between the polishing head and the pipe mouth surface, thereby affecting the uniformity and accuracy of the polishing, but also these debris may cause scratches or damage in the subsequent polishing process, further affecting the polishing quality. In order to avoid this situation, the present invention is designed with a cleaning unit for cleaning the debris attached to the first polishing head 42, the second polishing head 43 and the third polishing head 44. Specifically, when the first polishing head 42, the second polishing head 43 and the third polishing head 44 need to be cleaned, the movable seat 31 moves on the automatic intelligent pipe cutting machine 1, so that the polishing unit moves as a whole. During this process, the second gear 34 will mesh 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, causing the mounting plate 32 and the fixed plate 35 to flip over. When the second gear 34 is separated from the second rack 37, the second rotating shaft 33 rotates 180 degrees, so that the mounting plate 32 and the fixing plate 35 are turned over 180 degrees. In this case, the first grinding head 42, the second grinding head 43 and the third grinding head 44 can be rotated to a position facing the bristles 73. After the turning is completed, the movable seat 31 continues to move until the first grinding head 42, the second grinding head 43 and the third grinding head 44 are in contact with the bristles 73. When the first grinding head 42, the second grinding head 43 When the bristles 73 come into contact with the third grinding head 44, the movable base 31 stops moving, and then the motor 48 starts, driving the first grinding head 42, the second grinding head 43, and the third grinding head 44 to rotate. When the first grinding head 42, the second grinding head 43, and the third grinding head 44 rotate, the bristles 73 brush the first grinding head 42, the second grinding head 43, and the third grinding head 44, and brush off the debris attached to them, thereby cleaning the first grinding head 42, the second grinding head 43, and the third grinding head 44.

[0058] As the moving seat 31 approaches the cleaning plate 72, the push block 810 is squeezed against 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 push block 810, which enables the push block 810 to push the push rod in the driving member 86 to move. When the push rod in the driving member 86 moves, the gas in the sealing cylinder in the driving member 86 can be pressed into the sealing cylinder in the executive member 85 through the gas supply pipe 87, so that the gas pushes the push rod in the executive member 85 to move, and finally the third rack 84 moves. Under the cooperation of the driving member 86 and the executive member 85, as the moving seat 31 approaches 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, so that the winding wheel 81 reels in the connecting rope 82. When the connecting rope 82 is reeled in, the connecting rope 82 can be The lifting plate 74 is pulled up to move upward. Based on the above process, after the back plate 41 is flipped over, the lifting plate 74 moves just 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 an air pumping action and extracts the gas in the actuator 85, causing the third rack 84 to move down and reset. When the third rack 84 is reset, it drives the sixth gear 83 to rotate in the opposite direction, so that the winding wheel 81 releases the connecting rope 82. When the connecting rope 82 is released, the lifting plate 74 descends under the action of gravity. During this process, the several comb teeth 75 on the lifting plate 74 can scrape off the debris attached to the bristles 73, thereby cleaning the bristles 73 to ensure the subsequent cleaning effect of the bristles 73 on the first grinding head 42, the second grinding head 43 and the third grinding head 44;

[0059] It is worth noting 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 slidably mounted on the two guide rods to provide limit for the up and down movement of the lifting plate 74. In addition, two inclined surfaces are provided on the push block 810. When the push rod in the driving member 86 moves to the limit position, the push rod cannot continue to move. At this time, the push rod will squeeze the inclined surface on the push block 810, causing the push block 810 to move up. This design can avoid motion interference between the push 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 a prior art, which is not shown in the figure and will not be elaborated on here. Preferably, the moving unit can be moved by the cooperation of a motor, a gear and a rack, or it can be driven by a cylinder.
