During the transportation process, the grinding component can grind the end of the stainless steel seamless pipe, so that the burrs on the cut surface of the stainless steel seamless pipe can be polished, so that the burrs on the cut surface of the stainless steel seamless pipe are less, effectively avoiding the existence of burrs on the cut surface of the stainless steel seamless pipe, which is easy to affect the processing of the stainless steel seamless pipe.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, the grinding assembly includes a second support arm 11; a pair of symmetrically arranged second support arms 11 are fixedly connected to the top of the operating table 6; a lifting seat 12 is provided above the second support arm 11, and the two lifting seats 12 are symmetrically arranged; an electric push rod is fixedly connected to the top of the lifting seat 12, and the output end of the electric push rod is fixedly connected to the top position of the second support arm 11; a sliding seat 13 is fixedly connected to the end of the lifting seat 12; a second sliding frame 15 is slidably connected inside the sliding seat 13; the two ends of the second sliding frame 15 are slidably connected at the internal position of the sliding seat 13 respectively; a second threaded rod 14 is rotatably connected inside the sliding seat 13; the second threaded rod 14 is threadedly connected to the second sliding frame 15; the first The bottom of the second sliding frame 15 is rotatably connected with a rotating seat 16; two grinding blocks 17 are slidably connected inside the rotating seat 16, and springs are fixedly connected between the grinding blocks 17 and the side walls of the rotating seat 16; a guide rod 18 is fixed inside the rotating seat 16; the grinding block 17 is slidably connected to the guide rod 18; an adjusting block 20 is provided below the operating table 6; a synchronous wheel 21 is rotatably connected inside the adjusting block 20; two rubber synchronous belts 19 are connected to the synchronous wheel 21, and the two rubber synchronous belts 19 are respectively arranged at positions corresponding to both sides of the second support arm 11; the other end of the rubber synchronous belt 19 is arranged at a position corresponding to the internal through hole of the processing frame 7; when working, when cutting the stainless steel seamless pipe Before cutting, the stainless steel seamless pipe can be passed through the bottom of the rubber synchronous belt 19. Then, during the process of the contact roller 3 conveying the stainless steel seamless pipe, one end of the stainless steel seamless pipe can be first inserted into the position between the two grinding blocks 17, and the stainless steel seamless pipe can be driven to rotate by the rotation of the rubber synchronous belt 19 to grind the end of the stainless steel seamless pipe. After grinding, the second threaded rod 14 can be controlled to rotate so that the grinding block 17 is separated from the stainless steel seamless pipe, and the lifting seat 12 is driven to rise by the electric push rod so that the stainless steel seamless pipe can pass through the bottom of the rotating seat 16. After cutting is completed, the cut stainless steel seamless pipe is conveyed by the contact roller 3 on the side of the processing frame 7 close to the second support arm 11, so that the stainless steel seamless pipe can pass through the bottom of the rotating seat 16. The end of the tube stays at the position at the bottom of the corresponding rotating seat 16, and the lifting seat 12 is controlled to descend, and the rotating seat 16 is controlled to rotate at the same time, so that the grinding block 17 faces the end position of the corresponding stainless steel seamless tube, and then the second threaded rod 14 is controlled to rotate, driving the grinding block 17 to be sleeved on the end of the stainless steel seamless tube, and the stainless steel seamless tube is driven to rotate by the rotation of the rubber synchronous belt 19 to grind the end of the stainless steel seamless tube, so that the burrs at both ends of the stainless steel seamless tube can be removed, effectively avoiding the burrs from affecting the processing and use of the stainless steel seamless tube. During the cutting process, in order to avoid the rubber synchronous belt 19 from detaching from the stainless steel seamless tube, the subsequent stainless steel seamless tube can be used to push out the front end of the stainless steel seamless tube.

[0031] like Figures 4 to 5 As shown, an electric push rod is installed at the bottom of the operating table 6, and the adjustment block 20 is fixedly connected to the output end of the electric push rod; during operation, when the stainless steel seamless pipe is polished, the height of the adjustment block 20 can be adjusted by the electric push rod, so that the rubber synchronous belt 19 and the stainless steel seamless pipe can be attached more closely, the friction between the rubber synchronous belt 19 and the stainless steel seamless pipe can be greater, and the rubber synchronous belt 19 can drive the stainless steel seamless pipe to rotate more stably.

[0032] like Figure 1 As shown, a plurality of support frames 22 are fixedly connected to the top of the support base 1; support rollers 23 are rotatably connected to the support frames 22; the support rollers 23 are arranged between every two first support arms 2; the support rollers 23 are regularly arranged in a linear array, and the heights of the support rollers 23 are arranged corresponding to the through holes of the processing frame 7; when working, in the process of conveying the stainless steel seamless pipe, the support rollers 23 are provided to support the stainless steel seamless pipe, which can effectively avoid the stainless steel seamless pipe from sagging during the conveying process, thereby making the conveying of the stainless steel seamless pipe more stable.

[0033] like Figure 6 As shown, the surface of the support roller 23 is arranged in an arc shape, and the surfaces of the contact roller 3 and the feed roller 5 are also arranged in an arc shape; during operation, when the stainless steel seamless pipe is conveyed by the contact roller 3, the feed roller 5 and the support roller 23, the stainless steel seamless pipe will move to the lowest point of the top surface of the contact roller 3, the feed roller 5 and the support roller 23, so that the stainless steel seamless pipe can be more accurately introduced into the through hole of the processing frame 7, thereby making the conveying of the stainless steel seamless pipe more accurate.

[0034] like Figure 1 As shown, a limit block 24 is fixedly connected to the side wall of the sliding block 4; the limit block 24 is slidably connected to the internal position of the first support arm 2; during operation, when the sliding block 4 slides inside the first support arm 2, the sliding of the limit block 24 is restricted by the first support arm 2, so that the sliding block 4 can be more stable when sliding.

[0035] like Figure 2 As shown, a positioning rod 25 is fixedly connected to the inside of the processing frame 7; the positioning rod 25 is arranged in parallel with the first threaded rod 9; the first sliding frame 8 is slidably connected to the positioning rod 25; when working, when the first sliding frame 8 slides inside the processing frame 7, the sliding of the first sliding frame 8 is restricted by setting the positioning rod 25 inside the processing frame 7, so that the sliding of the first sliding frame 8 can be made more stable, so that the cutting saw blade 10 can cut the stainless steel seamless pipe more stably.

[0036] like Figure 1 and Figure 6As shown, a connecting arm 26 is fixedly connected to the side wall of the sliding block 4 on the same side; an electric push rod is installed on the top of the first support arm 2 in the middle, and the output end of the electric push rod is fixedly connected to the top position of the sliding block 4; when working, in the process of conveying the stainless steel seamless pipe, the height of the sliding block 4 can be adjusted, and the sliding block 4 is connected through the connecting arm 26, so that the spacing between the feeding roller 5 and the contact roller 3 can be adapted to the size of the stainless steel seamless pipe, thereby achieving a better effect of conveying the stainless steel seamless pipe.

[0037] like Figure 2 As shown, a positioning block 27 is fixedly connected to the end of the first threaded rod 9; the positioning block 27 is rotatably connected to the internal position of the processing frame 7; during operation, when the first threaded rod 9 rotates inside the processing frame 7, the processing frame 7 limits the rotation of the positioning block 27, so that the positioning block 27 is less likely to tilt during the rotation process, making the rotation of the first threaded rod 9 more stable.

[0038] like Figure 2 As shown, a plurality of anti-wear balls 28 are arranged between the processing frame 7 and the positioning block 27; the side walls of the anti-wear balls 28 are in contact with the side walls of the processing frame 7 and the positioning block 27; during operation, when the positioning block 27 rotates inside the processing frame 7, by arranging the anti-wear balls 28 between the processing frame 7 and the positioning block 27, the sliding friction between the processing frame 7 and the positioning block 27 can be converted into rolling friction, so that the friction force between the processing frame 7 and the positioning block 27 is smaller, thereby making the friction force between the processing frame 7 and the positioning block 27 smaller.

[0039] During operation, when it is necessary to cut the stainless steel seamless pipe, the stainless steel seamless pipe can be passed through the contact roller 3 and the feeding roller 5, and then the contact roller 3 can be controlled to rotate, and the stainless steel seamless pipe can be pressed by the feeding roller 5, so that the stainless steel seamless pipe can be pushed to the internal position of the through hole of the processing frame 7, and the first threaded rod 9 is controlled to rotate so that the first threaded rod 9 cooperates with the thread of the first sliding frame 8, driving the first sliding frame 8 to slide downward to cut the stainless steel seamless pipe, so that the stainless steel seamless pipe can be cut, and then the stainless steel seamless pipe can be transported by the contact roller 3 on the first supporting arm 2 in the middle. During the transportation process, the grinding assembly can grind the end of the stainless steel seamless pipe, so that the burrs on the cut surface of the stainless steel seamless pipe can be polished, so that the burrs on the cut surface of the stainless steel seamless pipe are reduced, effectively avoiding the existence of burrs on the cut surface of the stainless steel seamless pipe, which is easy to affect the processing of the stainless steel seamless pipe.

[0040] Before cutting the stainless steel seamless pipe, the stainless steel seamless pipe can be passed through the bottom of the rubber synchronous belt 19. Then, in the process of conveying the stainless steel seamless pipe by the contact roller 3, one end of the stainless steel seamless pipe can be first inserted into the position between the two grinding blocks 17, and the stainless steel seamless pipe can be driven to rotate by the rotation of the rubber synchronous belt 19 to grind the end of the stainless steel seamless pipe. After grinding, the second threaded rod 14 can be controlled to rotate so that the grinding block 17 is separated from the stainless steel seamless pipe, and the lifting seat 12 is driven to rise by the electric push rod so that the stainless steel seamless pipe can pass through the bottom of the rotating seat 16. After cutting is completed, the cut stainless steel seamless pipe is conveyed by the contact roller 3 on the side of the processing frame 7 close to the second support arm 11, so that The end of the stainless steel seamless pipe stays at the bottom position of the corresponding rotating seat 16, and the lifting seat 12 is controlled to descend, and the rotating seat 16 is controlled to rotate at the same time, so that the grinding block 17 faces the end position of the corresponding stainless steel seamless pipe, and then the second threaded rod 14 is controlled to rotate, driving the grinding block 17 to be sleeved on the end of the stainless steel seamless pipe, and the stainless steel seamless pipe is driven to rotate by the rotation of the rubber synchronous belt 19 to grind the end of the stainless steel seamless pipe, so that the burrs at both ends of the stainless steel seamless pipe can be removed, effectively avoiding the situation where the burrs affect the processing and use of the stainless steel seamless pipe. During the cutting process, in order to avoid the rubber synchronous belt 19 from detaching from the stainless steel seamless pipe, the subsequent stainless steel seamless pipe can be used to push out the front end of the stainless steel seamless pipe.

[0041] When grinding the stainless steel seamless pipe, the height of the adjustment block 20 can be adjusted by the electric push rod, so that the rubber synchronous belt 19 and the stainless steel seamless pipe can be attached more closely, the friction between the rubber synchronous belt 19 and the stainless steel seamless pipe can be greater, and the rubber synchronous belt 19 can drive the stainless steel seamless pipe to rotate more stably.

[0042] In the process of conveying the stainless steel seamless pipe, the support rollers 23 are provided to support the stainless steel seamless pipe, which can effectively prevent the stainless steel seamless pipe from sagging during the conveying process, thereby making the conveying of the stainless steel seamless pipe more stable.

[0043] When being transported by the contact roller 3, the feed roller 5 and the support roller 23, the stainless steel seamless pipe will move to the lowest point of the top surface of the contact roller 3, the feed roller 5 and the support roller 23, so that the stainless steel seamless pipe can be more accurately introduced into the through hole of the processing frame 7, thereby making the transportation of the stainless steel seamless pipe more accurate.

[0044] When the sliding block 4 slides inside the first support arm 2 , the first support arm 2 limits the sliding of the limit block 24 , so that the sliding block 4 can be more stable when sliding.

[0045] When the first sliding frame 8 slides inside the processing frame 7, a positioning rod 25 is provided inside the processing frame 7 to limit the sliding of the first sliding frame 8, so that the sliding of the first sliding frame 8 can be more stable, so that the cutting saw blade 10 can cut the stainless steel seamless pipe more stably.

[0046] During the conveying of the stainless steel seamless pipe, the height of the sliding block 4 can be adjusted and connected via the connecting arm 26, so that the distance between the feed roller 5 and the contact roller 3 can be adapted to the size of the stainless steel seamless pipe, thereby achieving a better conveying effect for the stainless steel seamless pipe.

[0047] When the first threaded rod 9 rotates inside the processing frame 7, the processing frame 7 limits the rotation of the positioning block 27, so that the positioning block 27 is less likely to tilt during the rotation process, making the rotation of the first threaded rod 9 more stable.

[0048] When the positioning block 27 rotates inside the processing frame 7, by arranging the anti-wear ball 28 between the processing frame 7 and the positioning block 27, the sliding friction between the processing frame 7 and the positioning block 27 can be changed into rolling friction, so that the friction force between the processing frame 7 and the positioning block 27 is smaller, thereby making the friction force between the processing frame 7 and the positioning block 27 smaller.
