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

[0049] Cleaning: The driving motor drives the wheel body 4 to rotate, and the wheel body 4 rubs the stainless steel tube 101 to rotate slowly. At the same time, foreign objects on the surface of the stainless steel tube 101 are manually cleaned to prevent protrusions from squeezing on the wheel body 4, causing the stainless steel tube 101 to radially jump and affect subsequent processing;

[0050] Cutting: The screw connected to the cutting motor 6 is driven to rotate, and 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 a high speed. At the same time, the stainless steel tube 101 rotates slowly under the rubbing of the wheel body 4.

At the same time, the cutting motor 9 drives the cutting wheel 10 to rotate at a high speed, and the cutting wheel 10 cuts the stainless steel pipe 101 along the middle of the notch 8. At this time, a longer stainless steel pipe 101 is cut into two shorter stainless steel pipes 101;

[0052] Unloading: Take down the cut stainless steel pipe 101 by forklift or crane;

[0053] The stainless steel pipe slitting machine is provided with a cutting component and a cutting component, which cooperate with each other to process the stainless steel pipe 101, and successively complete the cutting into grooves and cutting into sections. During the process, there is no need to transfer the stainless steel pipe 101 material. Compared with the current processing method, it can save multiple links and help improve the production and processing efficiency. When the cutting component is executed, two grooves can be processed at the same time, and the efficiency is also improved.

[0054] Reference Figure 1 - Figure 6 ,as well as Fig.10 , both sides of the support unit are provided with a transmission unit, the transmission unit is used to transmit the stainless steel pipe 101, and each transmission unit includes a truss 12, the truss 12 is rotatably connected with a transmission wheel 13, 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 arranged below the middle of the two trusses 12, the output end of the top material motor 15 is fixedly connected with a No. 2 screw rod 16, the output end of the No. 2 screw rod 16 extends to the end of the truss 12, and the No. 2 screw rod 16 is threadedly connected with a connecting block 17, and the two sides of the connecting block 17 are rotatably connected with rollers 18, and the rollers 18 are attached to the surface of the wedge block 14 and roll;

[0055] Considering that the diameter of the stainless steel tube 101 has various specifications, when the stainless steel tube 101 with a relatively small diameter is mounted on the rectangular frame 1, in order to ensure that the wheel body 4 can lift the stainless steel tube 101 and enable the stainless steel tube 101 to be mounted on the rectangular frame 1, the distance between the two sliders 3 can be adjusted to drive the No. 1 screw rod 2 to rotate, and the No. 1 screw rod 2 drives the two sliders 3 thereon to move relatively, approach and push up the stainless steel tube 101, so that the stainless steel tube 101 with a relatively small diameter can also be lifted and separated from the rectangular frame 1;

[0056] Considering that the length of the stainless steel pipe 101 has various specifications, and the stability of the stainless steel pipe 101 needs to be considered when placing the longer stainless steel pipe 101, a conveying unit is provided for this purpose. The conveying unit is not only used for conveying the stainless steel pipe 101, but also can stabilize the entire longer stainless steel pipe 101;

[0057] The transmission wheels 13 on the two trusses 12 close to the rectangular frame 1 are actively rotated and connected to the servo motor 19 provided on the outer wall of the truss 12. The servo motor 19 can drive the transmission wheel 13 at this position to rotate and drive the stainless steel pipe 101 on its surface to move, so as to realize the precise axial movement of the stainless steel pipe 101.

[0058] Considering that both ends of the stainless steel pipe 101 cannot be cut when the whole stainless steel pipe 101 is initially placed, after the whole stainless steel pipe 101 is placed, the end of the whole stainless steel pipe 101 is moved to one side of the cutting wheel 7 by the actively rotating conveying wheel 13, so that the cutting wheel 7 can process the groove at the end of the whole stainless steel pipe 101;

[0059] The whole stainless steel pipe 101 is placed on the truss 12, and is lifted and pushed forward by the transmission wheel 13. At this time, the stainless steel pipe 101 may touch the end surface of the wheel body 4. A lifting assembly is provided for this purpose. Before the transmission wheel 13 transmits the stainless steel pipe 101, the height of the stainless steel pipe 101 is lifted by the lifting 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 during transmission. The specific operation is to drive the lifting motor 15, the lifting motor 15 drives the second screw rod 16 to rotate, the second screw rod 16 drives the connecting block 17 to move, and the connecting block 17 drives the roller 18 to move along the lower surface of the wedge block 14 and push up the truss 12. The second screw rod 16 is erected on the ground through a plurality of bearing seats 20 to ensure that the second screw rod 16 supports the truss 12 and the stainless steel pipe 101;

[0060] The truss 12 and the stainless steel pipe 101 rise, and then drive the active transmission wheel 13 to transmit the stainless steel pipe 101 to the cutting assembly position. Then the top material motor 15 rotates in the opposite direction, and the connecting block 17 moves in the opposite direction. During the reverse movement process, the truss 12 and the stainless steel pipe 101 move downward, and at the same time control the roller 18 to support the wedge block 14, so that the transmission wheel 13 and the wheel body 4 on the truss 12 can synchronously set the stainless steel pipe 101 in a horizontal state, which is helpful for subsequent cutting and cutting operations.

[0061] Reference Figure 1 - Fig.10 Each rectangular frame 1 is provided with a pressing assembly, which can constrain the stainless steel pipe 101 on the rectangular frame 1, and the pressing assembly includes a No. 1 cylinder 21 arranged at the corner position of the upper surface of the rectangular frame 1, and the output ends of the two No. 1 cylinders 21 on the same side of the length direction of the rectangular frame 1 are fixedly connected with a horizontal plate 22;

[0062] The stainless steel pipe 101 is mounted on the wheel body 4. At this time, the stainless steel pipe 101 is in a free state in the vertical direction, that is, when the wheel body 4 rubs the stainless steel pipe 101 to rotate, the stainless steel pipe 101 is in a state of jumping upward, causing the wheel body 4 to fall off the surface of the stainless steel pipe 101, resulting in slippage, resulting in the stainless steel pipe 101 rotating unstably, affecting the cutting and cutting, especially in the process of cutting and breaking into two sections, the stability of the stainless steel pipe 101 will be reduced again, the end of the stainless steel pipe 101 will be tilted, and in severe cases, the stainless steel pipe 101 will squeeze the cutting wheel 10;

[0063] For this purpose, a downward pressing assembly is provided. During specific operation, the stainless steel pipe 101 is mounted on the wheel body 4, and then the downward pressing assembly is driven. The No. 1 cylinder 21 drives the cross plate 22 to move downward. The cross plate 22 is close to the surface of the stainless steel pipe 101, and the spacing is controlled at 1-2 mm. That is, the cross plate 22 can restrain the vertical jumping of the stainless steel pipe 101, and at the same time, the stable rotation of the stainless steel pipe 101 is guaranteed, that is, the cross plate 22 fails to hinder the rotation of the stainless steel pipe 101.

[0064] Reference Figure 1 - Fig.12 Each of the horizontal plates 22 is provided with an adjustment component, which includes an adjustment motor 23 arranged at one end of the horizontal plate 22, and the output end of the adjustment motor 23 is fixedly connected to a No. 3 screw rod 24, and a block 25 is symmetrically threaded on the No. 3 screw rod 24, and the block 25 slides and penetrates to the bottom of the horizontal plate 22, and the lower surfaces of two adjacent blocks 25 are arranged in an "eight" shape, and the two adjacent blocks 25 can be squeezed on the surface of the stainless steel pipe 101; by setting the "eight"-shaped block 25, the block 25 can further restrain the beating of the stainless steel pipe 101, that is, the stainless steel pipe 101 01 is constrained in the tilting direction on both sides of the vertical, and at the same time, the No. 1 cylinder 21 drives the horizontal plate 22 to move up and down, and adjusts the distance between the horizontal plate 22 and the stainless steel tube 101 as a rough adjustment, and then controls the adjustment motor 23 to drive the No. 3 screw rod 24 to rotate slowly, and the No. 3 screw rod 24 drives the two blocks 25 to move relative to each other, and adjusts the distance between the two adjacent blocks 25, and also adjusts the distance between the lower surface of the block 25 and the stainless steel tube 101. This adjustment can achieve fine adjustment, and the distance between the lower surface of the block 25 and the stainless steel tube 101 can be accurately controlled to be 1-2 mm.

[0065] Reference Figure 1 - Fig.11 A grinding assembly is provided between the two horizontal plates 22 in the middle position, and the grinding assembly is used to grind the cut edge of the stainless steel pipe 101, and 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, and a No. 2 cylinder 27 is fixedly connected to the upper end surface of the frame 26, and the output end of the No. 2 cylinder 27 passes through the frame 26 and is fixedly connected to a grinding motor 28, and a grinding wheel 29 is fixedly connected to the output end of the grinding motor 28;

[0066] The cutting wheel 7 cuts a notch 8 on the stainless steel pipe 101, and then the cutting wheel 10 cuts a gap 30 in the notch 8 to achieve the slitting of the stainless steel pipe 101. Then the No. 2 cylinder 27 drives the grinding motor 28 to move downward, and the grinding motor 28 drives the grinding wheel 29 to rotate at high speed. The grinding wheel 29 rotates along the gap 30 and grinds the surface of the notch 8 and the surface of the gap 30 to clean the burrs on the surface, which helps the subsequent precise matching installation and welding of the stainless steel pipe 101 and the flange. At the same time, a grinding component is set on the stainless steel pipe slitting machine, which can also reduce subsequent grinding operations. Cutting, cutting and grinding are completed at one time, which can improve processing efficiency.

[0067] Reference Figure 1 - Fig.13 , a rotation groove 31 is provided on the outer side wall of the two horizontal plates 22 at the middle position, and the bottom two sides of the frame body 26 are rotatably connected in the rotation groove 31;

[0068] The grinding wheel 29 is configured as follows: Fig.11 As shown, the edge of the grinding wheel 29 is designed to be flat, and the edge transitions to the inner side of the grinding wheel 29 through a bevel. The bevel can grind the surface of the recess 8, and the flat edge can extend to the cutting slit 30 of the stainless steel pipe 101; and the bottom two sides of the frame 26 are connected to the cross plate 22 by rotation, and the No. 2 cylinder 27 connected to the cross plate 22 can be adjusted to adjust the height of the two cross plates 22, so that the frame 26 is in a slightly tilted state, so that the grinding wheel 29 is also in a tilted state, and can grind more areas on the surface of the recess 8, as well as the edge position inside the cutting slit 30, so that the grinding is more thorough.

[0069] Reference Figure 1 - Fig.13 A groove 32 is formed on the lower surface of each of the clamping blocks 25, and a plurality of extrusion wheels 33 are rotatably connected in each groove 32, and the two sides of the middle of the extrusion wheels 33 are provided with reduced diameters;

[0070] The shape of the extrusion wheel 33 is as follows: Fig.13 As shown, the middle position of the extrusion wheel 33 is pressed on the surface of the stainless steel tube 101, and the extrusion wheel 33 rotates with the rotation of the stainless steel tube 101, and when the frame 26 is in a tilted state, the extrusion wheel 33 will not affect the rotation of the stainless steel tube 101; the extrusion wheel 33 is provided, and its purpose is to avoid the block 25 from directly being pressed and contacted with the surface of the stainless steel tube 101 when the frame 26 is tilted, but to contact the surface of the stainless steel tube 101 through the rotatable extrusion wheel 33, while stabilizing the stainless steel tube 101, it will not affect the rotation of the stainless steel tube 101 itself.

[0071] Reference Figure 1 , Fig.14 and Fig.15, each of the transmission wheels 13 has a plurality of ball grooves 34 on its surface, and each ball groove 34 has a ball 35 in it;

[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 transmission wheel 13. A ball 35 is arranged on the surface of the transmission wheel 13. When the stainless steel tube 101 rotates, the ball 35 can be rubbed to rotate, thereby reducing the rotation resistance of the transmission wheel 13 to the stainless steel tube 101, so that the stainless steel tube 101 can rotate smoothly and stably.

[0073] Reference Figure 1 , Fig.14 and Fig.15 , one side of each truss 12 is hollow inside, and one side of the truss 12 is connected to an oil supply pipe 36;

[0074] Each of the transmission wheels 13 has a cavity 37 formed inside, the cavity 37 is connected to the ball groove 34, and the cavity 37 is connected to the transmission wheel 13. One end of the transmission wheel 13 has a liquid inlet hole 38, and the liquid inlet hole 38 penetrates to the outer surface of the end of the transmission wheel 13;

[0075] An external oil pump injects lubricating oil into the oil supply pipe 36, and then the lubricating oil flows along the hollow part of the truss 12, and then the lubricating oil flows into the cavity 37 along the liquid inlet hole 38 at one end of the transmission wheel 13, and then the lubricating oil flows into the ball groove 34 to lubricate the ball 35 in the ball groove 34. This design takes into account that when the stainless steel tube 101 rotates, the dust on the surface of the stainless steel tube 101 will rotate with the ball 35 to the ball groove 34, affecting the rolling of the ball 35, while the lubricating oil can flow into the ball groove 34, and can ensure the smooth rolling of the ball 35 and the stable rotation of the stainless steel tube 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, and can also improve the stability of the up and down adjustment of the truss 12.

[0076] Reference Figure 1 and Figure 4 A guide rod 39 is fixedly connected to both sides of each slider 3, and the end of the guide rod 39 is slidably connected to a guide groove 40 opened on the inner wall of the rectangular frame 1; the guide rod 39 is arranged to cooperate with the guide groove 40 to improve the movement stability and supporting force of the slider 3, so that the stainless steel pipe 101 can be stably mounted on the wheel body 4.

At the same time, foreign objects on the surface of the stainless steel tube 101 are manually cleaned to prevent protrusions from squeezing on the wheel body 4, causing the stainless steel tube 101 to radially jump and affect subsequent processing;

[0080] Cutting: The conveying 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 a 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, cuts the stainless steel tube 101 layer by layer, and cuts out a ring-shaped notch 8. The cutting does not penetrate the inner wall of the stainless steel tube 101. The cross section of the notch 8 is in the shape of an isosceles trapezoid. The inclined surfaces on both sides of the notch 8 become the subsequent groove position.

[0081] Cutting: When the last level of cutting is performed, the screw connected to the cutting motor 9 is driven to rotate, and 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 a high speed, and the cutting wheel 10 cuts the stainless steel pipe 101 along the middle of the notch 8. At this time, a longer stainless steel pipe 101 is cut into two shorter stainless steel pipes 101;

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