Description

Technical Field

[0001] This invention relates to the field of stainless steel pipe processing, specifically a stainless steel pipe slitting machine. Background Technology

[0002] Stainless steel pipes are widely used in many fields such as construction, industrial pipeline equipment, chemical industry, and automobile manufacturing. In the production of fire protection pipelines, a long pipe needs to be cut into multiple shorter sections. At the same time, in order to facilitate welding with flanges, bevels are usually processed at the ends of the pipes to improve the welding quality between the pipes and flanges.

[0003] Current cutting equipment has a relatively simple function, limited to one cutting function. Therefore, after cutting long pipes, it is necessary to transfer them to the beveling process. From cutting and segmenting to beveling, this process involves the feeding and unloading of pipes for cutting, as well as the feeding and unloading of pipes for beveling, which is quite cumbersome and needs to be improved in efficiency.

[0004] Therefore, a stainless steel pipe slitting machine is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0011] Preferably, the support unit is provided with a conveying unit on both sides. The conveying unit is used to convey stainless steel pipes, and each conveying unit includes a truss. A conveying wheel is rotatably connected to the truss. A wedge block is provided below the truss. A top material assembly is provided below the wedge block. The top material assembly includes a top material motor located below the middle of the two trusses. A second lead screw is fixed to the output end of the top material motor. The output end of the second lead screw extends to the end of the truss. A connecting block is threaded onto the second lead screw. Rollers are rotatably connected to both sides of the connecting block. The rollers roll against the surface of the wedge block.

[0012] Preferably, each rectangular frame is provided with a pressing component, which can constrain the stainless steel tube on the rectangular frame. The pressing component includes a first cylinder located at the corner of the upper surface of the rectangular frame, and the output ends of two first cylinders on the same side of the length direction of the rectangular frame are fixed with a horizontal plate.

[0013] Preferably, each of the horizontal plates is provided with an adjustment assembly, which includes an adjustment motor disposed at one end of the horizontal plate. The output end of the adjustment motor is fixedly connected to a No. 3 lead screw. A locking block is symmetrically threaded on the No. 3 lead screw. The locking block slides and passes through to the bottom of the horizontal plate, and the lower surfaces of two adjacent locking blocks are arranged in a figure-eight shape. The two adjacent locking blocks can press against the surface of the stainless steel tube.

[0014] Preferably, a grinding assembly is provided between the two horizontal plates in the middle position. The grinding assembly is used to grind the cut edge of the stainless steel pipe. The grinding assembly includes an inverted U-shaped frame. The bottom two sides of the frame are connected to the side walls of the horizontal plates. A second cylinder is fixed to the upper end of the frame. The output end of the second cylinder passes through the frame and is fixed to a grinding motor. A grinding wheel is fixed to the output end of the grinding motor.

[0015] Preferably, a rotating groove is opened on the outer wall of the two horizontal plates in the middle position, and the bottom two sides of the frame are rotatably connected in the rotating groove.

[0016] Preferably, a groove is formed on the lower surface of each card block, and multiple extrusion rollers are rotatably connected in each groove, with the extrusion rollers having a reduced diameter on both sides in the middle.

During this process, there is no need to transfer the stainless steel pipe material. Compared with the current processing method, it can save multiple steps and help improve production efficiency. Moreover, when the cutting assembly is in operation, it can process two bevels at the same time, which also improves efficiency.

[0023] 2. In this invention, the cutting wheel cuts a notch in the stainless steel pipe, and then cuts a slit in the notch to slit the stainless steel pipe. Next, the second cylinder drives the grinding motor to move down, and the grinding motor drives the grinding wheel to rotate at high speed. The grinding wheel rotates along the slit and grinds the surface of the notch and the slit, cleaning the burrs on their surfaces. This helps to ensure the precise fit and welding of the stainless steel pipe to the flange in the future. At the same time, the grinding component on the stainless steel pipe slitting machine can also reduce subsequent grinding operations. Cutting, slitting and grinding are completed in one go, which can improve processing efficiency. Attached Figure Description

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Reference Figure 1 - Figure 5 ,as well as Figure 10 A stainless steel pipe slitting machine includes a support unit, on which a cutting component and a cutting assembly are provided;

[0042] The support unit includes two rectangular frames 1 symmetrically erected on the ground. Each rectangular frame 1 is equipped with a drive assembly for driving the stainless steel tube 101 to rotate. The drive assembly includes a lead screw 2 arranged inside the rectangular frame 1. A slider 3 is threadedly connected to the lead screw 2. A drive motor is provided on both sides of the upper end of the slider 3. A wheel 4 is fixed to the end of the drive motor. The surface of the stainless steel tube 101 is pressed against the surface of the wheel 4.

[0043] A substrate 5 is disposed between the two rectangular frames 1, a cutting assembly is disposed on one side of the substrate 5, and a cutting assembly is disposed on the other side of the substrate 5;

[0044] The cutting assembly includes a cutting motor 6 slidably connected to the substrate 5, and a cutting wheel 7 is fixedly connected to the output end of the cutting motor 6. The cutting wheel 7 can cut an annular notch 8 on the surface of the stainless steel tube 101.

[0045] The cutting assembly includes a cutting motor 9 slidably connected to the substrate 5, and a cutting wheel 10 is fixedly connected to the output end of the cutting motor 9. The cutting wheel 10 can cut the stainless steel tube 101 into two sections at the annular notch 8.

[0046] In this embodiment, the lower surface of the substrate 5 and the lower surface of the rectangular frame 1 are both mounted on the ground by the support rod 11; the end shell of the drive motor is fixed to the slider 3, and the output end of the drive motor is fixed to the wheel 4, which can rotate the stainless steel tube 101 on it.

[0047] The end housing of the cutting motor 6 is slidably connected to a sliding hole opened on one side of the substrate 5, and a screw that drives the cutting motor 6 to reciprocate is provided in the sliding hole, and a motor is fixedly connected to the end of the screw; the end housing of the cutting motor 9 is also slidably connected to a sliding hole opened on the other side of the substrate 5, and a screw that drives the cutting motor 9 to reciprocate is provided in the sliding hole, and a motor is also fixedly connected to the end of the screw.

[0048] Loading: The stainless steel pipe 101 is transferred to the two rectangular frames 1 by a forklift or crane, and the stainless steel pipe 101 sits on the wheel body 4;

[0049] Cleaning: The drive motor drives the wheel 4 to rotate, and the wheel 4 rubs the stainless steel tube 101 to rotate slowly. At the same time, the foreign objects on the surface of the stainless steel tube 101 are cleaned by the manual to prevent any protrusions from pressing on the wheel 4, which would cause the stainless steel tube 101 to run radially and affect subsequent processing.

[0050] Cutting: The screw connected to the cutting motor 6 is driven to rotate. The cutting motor 6 drives the cutting wheel 7 to gradually approach the surface of the stainless steel tube 101. The cutting motor 6 drives the cutting wheel 7 to rotate at high speed. At the same time, the stainless steel tube 101 rotates slowly under the rubbing of the wheel body 4. The cutting wheel 7 feeds slowly and cuts the stainless steel tube 101 layer by layer, and cuts out a ring-shaped notch 8. The cut does not penetrate the inner wall of the stainless steel tube 101. The cross-section of the notch 8 is an isosceles trapezoid. The two inclined surfaces of the notch 8 become the subsequent bevel positions.

[0051] Cutting: During the final cutting process, the screw connected to the cutting motor 9 is driven to rotate. The cutting motor 9 drives the cutting wheel 10 to gradually approach the notch 8. At the same time, the cutting motor 9 drives the cutting wheel 10 to rotate at high speed. The cutting wheel 10 cuts the stainless steel tube 101 along the middle of the notch 8. At this time, a longer section of stainless steel tube 101 is cut into two shorter sections of stainless steel tube 101.

[0052] Unloading: Use a forklift or crane to remove the slit stainless steel pipe 101;

[0053] This stainless steel pipe slitting machine is equipped with a cutting component and a cutting assembly that work together to process the stainless steel pipe 101, sequentially cutting it into bevels and slitting it into sections. During this process, there is no need to transfer the stainless steel pipe 101 material. Compared with the current processing method, it can save multiple steps and help improve production efficiency. Moreover, when the cutting assembly is in operation, it can process two bevels at the same time, which also improves efficiency.

[0054] Reference Figure 1 - Figure 6 ,as well as Figure 10 The support unit is provided with a conveying unit on both sides. The conveying unit is used to convey the stainless steel pipe 101. Each conveying unit includes a truss 12. A conveying wheel 13 is rotatably connected to the truss 12. A wedge block 14 is provided below the truss 12. A top material assembly is provided below the wedge block 14. The top material assembly includes a top material motor 15 located below the middle of the two trusses 12. A second lead screw 16 is fixedly connected to the output end of the top material motor 15. The output end of the second lead screw 16 extends to the end of the truss 12. A connecting block 17 is threadedly connected to the second lead screw 16. Rollers 18 are rotatably connected to both sides of the connecting block 17. The rollers 18 are attached to the surface of the wedge block 14 and roll.

[0055] Considering that stainless steel pipe 101 has various diameter specifications, when stainless steel pipe 101 with a relatively small diameter is mounted on rectangular frame 1, in order to ensure that the wheel body 4 can lift stainless steel pipe 101 and mount stainless steel pipe 101 on rectangular frame 1, the distance between the two relative sliders 3 can be adjusted to drive the first lead screw 2 to rotate. The first lead screw 2 drives the two sliders 3 on it to move relative to each other, approach and push up the stainless steel pipe 101, so that the stainless steel pipe 101 with a smaller diameter can also be lifted off rectangular frame 1.

[0056] Considering that stainless steel pipe 101 has various lengths and that the stability of stainless steel pipe 101 needs to be considered when placing it, a conveying unit is set up. The conveying unit is not only used for conveying stainless steel pipe 101, but also for stabilizing the entire long stainless steel pipe 101.

[0057] The conveyor wheels 13 on the two trusses 12 that are close to the rectangular frame 1 are actively rotating and are connected to the servo motors 19 installed on the outer side wall of the trusses 12. The servo motors 19 can drive the conveyor wheels 13 at this position to rotate and drive the stainless steel tubes 101 on their surface to move, so as to achieve precise axial movement of the stainless steel tubes 101.

[0058] Considering that the two ends of the stainless steel tube 101 were not cut when the entire stainless steel tube 101 was initially placed, after the entire stainless steel tube 101 was placed, the end of the entire stainless steel tube 101 was moved to one side of the cutting wheel 7 by the actively rotating transmission wheel 13, so that the cutting wheel 7 could process the bevel at the end of the entire stainless steel tube 101.

[0059] The entire stainless steel pipe 101 is placed on the truss 12 and is supported and pushed forward by the conveyor wheel 13. At this time, the stainless steel pipe 101 may touch the end face of the wheel body 4. Therefore, a top material assembly is set up. Before the conveyor wheel 13 conveys the stainless steel pipe 101, the height of the stainless steel pipe 101 is raised by the top material assembly so that the stainless steel pipe 101 is higher than the wheel body 4, ensuring that the stainless steel pipe 101 will not touch the wheel body 4 when it is being conveyed. Specifically, the top material motor 15 is driven, which drives the second lead screw 16 to rotate. The second lead screw 16 drives the connecting block 17 to move. The connecting block 17 drives the roller 18 to move along the lower surface of the wedge block 14 and push the truss 12 upward. The second lead screw 16 is supported on the ground by multiple bearing seats 20 to ensure that the second lead screw 16 supports the truss 12 and the stainless steel pipe 101.

[0060] The truss 12 and stainless steel pipe 101 rise, and then the drive conveyor wheel 13 is driven to convey the stainless steel pipe 101 to the cutting assembly position. After that, the top material motor 15 rotates in the opposite direction, and the connecting block 17 moves in the opposite direction. During the reverse movement, the truss 12 and stainless steel pipe 101 move down, and at the same time, the roller 18 is controlled to support the wedge block 14, so that the conveyor wheel 13 and the wheel body 4 on the truss 12 can synchronously set the stainless steel pipe 101 in a horizontal position, which helps the subsequent cutting and slicing operations.

[0061] Reference Figure 1 - Figure 10 Each rectangular frame 1 is provided with a pressing component, which can constrain the stainless steel tube 101 on the rectangular frame 1. The pressing component includes a first cylinder 21 located at the corner of the upper surface of the rectangular frame 1. The output ends of two first cylinders 21 on the same side of the length direction of the rectangular frame 1 are fixed with a horizontal plate 22.

[0062] Stainless steel tube 101 is mounted on wheel 4. At this time, stainless steel tube 101 is in a free state in the vertical direction. That is, when wheel 4 rubs stainless steel tube 101 to rotate, stainless steel tube 101 is jumping upward, causing wheel 4 to fall off the surface of stainless steel tube 101 and slipping. This makes the rotation of stainless steel tube 101 unstable, affecting cutting and cutting. Especially during the process of cutting into two sections, the stability of stainless steel tube 101 will decrease again, and the end of stainless steel tube 101 will tilt. In severe cases, stainless steel tube 101 will squeeze cutting wheel 10.

[0063] To address this, a pressing component was installed. In operation, the stainless steel tube 101 was mounted on the wheel 4, and then the pressing component was driven. The first cylinder 21 moved the horizontal plate 22 downward. The horizontal plate 22 was close to the surface of the stainless steel tube 101, and the distance between them was controlled at 1-2 mm. This allowed the horizontal plate 22 to constrain the vertical movement of the stainless steel tube 101 while ensuring the stable rotation of the stainless steel tube 101. In other words, the horizontal plate 22 did not obstruct the rotation of the stainless steel tube 101.

[0064] Reference Figure 1 - Figure 12 Each of the horizontal plates 22 is equipped with an adjustment assembly, which includes an adjustment motor 23 located at one end of the horizontal plate 22. A No. 3 lead screw 24 is fixedly connected to the output end of the adjustment motor 23. A locking block 25 is symmetrically threaded onto the No. 3 lead screw 24. The locking blocks 25 slide and extend to the bottom of the horizontal plate 22, and the lower surfaces of two adjacent locking blocks 25 are arranged in a figure-eight shape. Two adjacent locking blocks 25 can press against the surface of the stainless steel tube 101. By setting the figure-eight shaped locking blocks 25, the locking blocks 25 can further constrain the movement of the stainless steel tube 101, that is, to control the movement of the stainless steel tube 101. 01. The vertical tilt direction is constrained, and at the same time, the first cylinder 21 drives the horizontal plate 22 to move up and down. The distance between the horizontal plate 22 and the stainless steel tube 101 is adjusted for coarse adjustment. Then, the adjustment motor 23 drives the third lead screw 24 to rotate slowly. The third lead screw 24 drives the two locking blocks 25 to move relative to each other, adjusting the distance between the two adjacent locking blocks 25. At the same time, it also adjusts the distance between the lower surface of the locking block 25 and the stainless steel tube 101. This adjustment can achieve fine adjustment, and the distance between the lower surface of the locking block 25 and the stainless steel tube 101 can be precisely controlled within 1-2 mm.

[0065] Reference Figure 1 - Figure 11 A grinding assembly is provided between the two horizontal plates 22 in the middle position. The grinding assembly is used to grind the cut edge of the stainless steel pipe 101. The grinding assembly includes an inverted U-shaped frame 26. The bottom two sides of the frame 26 are connected to the side walls of the horizontal plate 22. A second cylinder 27 is fixed to the upper end of the frame 26. The output end of the second cylinder 27 passes through the frame 26 and is fixed to a grinding motor 28. A grinding wheel 29 is fixed to the output end of the grinding motor 28.

[0066] Cutting wheel 7 cuts a notch 8 on stainless steel pipe 101, and then cutting wheel 10 cuts a slit 30 in the notch 8 to slit the stainless steel pipe 101. Then, cylinder 27 drives grinding motor 28 to move down, and grinding motor 28 drives grinding wheel 29 to rotate at high speed. Grinding wheel 29 rotates along slit 30 and grinds the surface of notch 8 and slit 30 to clean the burrs on their surfaces. This helps to ensure the precise fit and welding of stainless steel pipe 101 with flange in the future. At the same time, the grinding component on the stainless steel pipe slitting machine can also reduce subsequent grinding operations. Cutting, slitting and grinding are completed in one go, which can improve processing efficiency.

[0067] Reference Figure 1 - Figure 13 Rotating grooves 31 are opened on the outer walls of the two horizontal plates 22 in the middle position, and the bottom sides of the frame 26 are rotatably connected in the rotating grooves 31.

[0068] The shape of the grinding wheel 29 is set, such as Figure 11 As shown, the grinding wheel 29 has a flat edge design, with the edge transitioning to the inner side of the grinding wheel 29 via a bevel. The bevel can grind the surface of the notch 8, and the flat edge can extend into the slit 30 of the stainless steel tube 101. The bottom two sides of the frame 26 are connected to the horizontal plate 22 by rotation. The second cylinder 27 connected to the horizontal plate 22 can be adjusted to adjust the height of the two horizontal plates 22, so that the frame 26 is in a slightly tilted state, thereby making the grinding wheel 29 also tilted, and able to grind more areas of the surface of the notch 8 and the inner edge of the slit 30, resulting in more thorough grinding.

[0069] Reference Figure 1 - Figure 13 Each of the card blocks 25 has a groove 32 on its lower surface, and multiple extrusion rollers 33 are rotatably connected in each groove 32. The extrusion rollers 33 are narrowed on both sides in the middle.

[0070] The extrusion roller 33 is shaped as follows Figure 13 As shown, the middle position of the extrusion roller 33 presses against the surface of the stainless steel tube 101. The extrusion roller 33 rotates with the rotation of the stainless steel tube 101, and the extrusion roller 33 does not affect the rotation of the stainless steel tube 101 when the frame 26 is tilted. The purpose of setting the extrusion roller 33 is to prevent the clamping block 25 from directly pressing against the surface of the stainless steel tube 101 when the frame 26 is tilted. Instead, the extrusion roller 33 contacts the surface of the stainless steel tube 101, stabilizing the stainless steel tube 101 without affecting its rotation.

[0071] Reference Figure 1 , Figure 14 and Figure 15Each of the conveyor wheels 13 has a plurality of ball grooves 34 on its surface, and each ball groove 34 contains a ball 35.

[0072] When the stainless steel tube 101 rotates around its own axis, the surface of the stainless steel tube 101 will rub against the surface of the conveyor wheel 13. A ball 35 is provided on the surface of the conveyor wheel 13. When the stainless steel tube 101 rotates, the ball 35 can be rubbed to rotate, reducing the rotational resistance of the conveyor wheel 13 on the stainless steel tube 101, so that the stainless steel tube 101 can rotate smoothly and stably.

[0073] Reference Figure 1 , Figure 14 and Figure 15 Each truss 12 has a hollow interior on one side, and an oil supply pipe 36 is connected to one side of the truss 12.

[0074] Each of the conveyor wheels 13 has a cavity 37 inside, the cavity 37 is connected to the ball groove 34, and a liquid inlet hole 38 is opened at one end of the cavity 37 and the liquid inlet hole 38 extends to the outer surface of the end of the conveyor wheel 13.

[0075] An external oil pump injects lubricating oil into the oil supply pipe 36. The lubricating oil then flows along the hollow part of the truss 12. Next, the lubricating oil flows into the cavity 37 of the transmission wheel 13 through the inlet hole 38 at one end. After that, the lubricating oil flows into the ball groove 34 to lubricate the ball 35 inside the ball groove 34. This design takes into account that when the stainless steel pipe 101 rotates, the dust on the surface of the stainless steel pipe 101 will rotate with the ball 35 to the ball groove 34, affecting the rolling of the ball 35. The lubricating oil can flow into the ball groove 34 and ensure the smooth rolling of the ball 35 and the stable rotation of the stainless steel pipe 101. At the same time, excess lubricating oil will drip onto the surface of the roller 18, directly lubricating the roller 18 and the wedge block 14, which can also improve the stability of the truss 12 in vertical adjustment.

[0076] Reference Figure 1 and Figure 4 Each slider 3 has a guide rod 39 fixedly connected to both sides, and the end of the guide rod 39 is slidably connected to the guide groove 40 opened on the inner wall of the rectangular frame 1. The guide rod 39 and the guide groove 40 are configured to improve the movement stability and support force of the slider 3, so that the stainless steel tube 101 can be stably mounted on the wheel body 4.

[0077] Working principle:

[0078] Loading: The stainless steel pipe 101 is transferred to two rectangular frames 1 by a forklift or crane, and the stainless steel pipe 101 sits on the wheel body 4 and the conveyor wheel 13;

[0079] Cleaning: The drive motor drives the wheel 4 to rotate, and the wheel 4 rubs the stainless steel tube 101 to rotate slowly. At the same time, the foreign objects on the surface of the stainless steel tube 101 are cleaned by the manual to prevent any protrusions from pressing on the wheel 4, which would cause the stainless steel tube 101 to run radially and affect subsequent processing.

[0080] Cutting: The conveyor wheel 13 moves the slitting position of the stainless steel tube 101 to the cutting assembly position, and then drives the screw connected to the cutting motor 6 to rotate. The cutting motor 6 drives the cutting wheel 7 to gradually approach the surface of the stainless steel tube 101. The cutting motor 6 drives the cutting wheel 7 to rotate at high speed. At the same time, the stainless steel tube 101 rotates slowly under the rubbing of the wheel body 4. The cutting wheel 7 feeds slowly and cuts the stainless steel tube 101 layer by layer, and cuts out a ring-shaped notch 8. The cut does not penetrate the inner wall of the stainless steel tube 101. The cross-section of the notch 8 is an isosceles trapezoidal shape. The two inclined surfaces of the notch 8 become the subsequent bevel positions.

[0081] Cutting: During the final cutting process, the screw connected to the cutting motor 9 is driven to rotate. The cutting motor 9 drives the cutting wheel 10 to gradually approach the notch 8. At the same time, the cutting motor 9 drives the cutting wheel 10 to rotate at high speed. The cutting wheel 10 cuts the stainless steel tube 101 along the middle of the notch 8. At this time, a longer section of stainless steel tube 101 is cut into two shorter sections of stainless steel tube 101.

[0082] Unloading: Use a forklift or crane to remove the slit stainless steel pipe 101.

[0083] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
