Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0041] Example 1, please refer to Figures 1 to 5 As shown:

[0042] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an automatic cutting device for a grooved anti-corrosion steel pipe, comprising a processing table 1, a supporting leg 2 is fixedly installed at the bottom of the processing table 1, a batch clamping assembly 3 is arranged on the processing table 1, and the batch clamping assembly 3 is used to clamp and position the anti-corrosion steel pipe 4 in batches, an alignment assembly 5 is arranged on the processing table 1, and the alignment assembly 5 is used to align the two ends of the anti-corrosion steel pipe 4 with each other, and a cutting assembly 6 is arranged on the alignment assembly 5, and the cutting assembly 6 is used to cut the anti-corrosion layer of the pipe mouth of the anti-corrosion steel pipe 4;

[0043] The batch clamping assembly 3 includes bearing seats 31 symmetrically mounted on both sides of the length direction of the processing table 1, a driving frame 32 is fixedly mounted on one of the bearing seats 31, a driving motor 33 is fixedly mounted on the driving frame 32, a driving shaft 34 is rotatably connected to the bearing seat 31, an output end of the driving motor 33 is fixedly connected to one end of the driving shaft 34, a clamping column 35 is fixedly sleeved on the middle part of the driving shaft 34, and a limiting ring plate 36 is rotatably sleeved on the outer surface of the clamping column 35, and a flip assembly 3 capable of positioning the limiting ring plate 36 is provided on the processing table 1 7. A clamping opening 38 is provided at the top of the limiting ring plate 36, and a plurality of clamping grooves 39 are evenly provided along the axis of the clamping column plate 35. A first clamping roller 310 is evenly provided along the axis of the limiting ring plate 36. A second driving motor 311 is fixedly installed on one side of the clamping opening 38, and an output end of the second driving motor 311 is fixedly connected to one end of the first clamping roller 310. A telescopic cylinder 313 is fixedly installed in the clamping groove 39, and a support plate 314 is fixedly connected to the telescopic end of the telescopic cylinder 313, and second clamping rollers 315 are rotatably connected to both sides of the width direction of the support plate 314.

[0044] Specifically, the anti-corrosion steel pipe 4 is placed in the clamping groove 39 from the clamping port 38, and then the driving motor 33 drives the driving shaft 34 to rotate so that the next clamping groove 39 is aligned with the clamping port 38. The operation is repeated until the clamping grooves 39 are filled with the anti-corrosion steel pipes 4. Then, the pipe clamping column 35 is deflected by a certain angle so that each first clamping roller 310 is aligned with the clamping groove 39. Then, the telescopic cylinder 313 is extended so that the anti-corrosion steel pipe 4 is positioned at three points by the second clamping roller 315 and the first clamping roller 310 to complete the loading. Then, the anti-corrosion steel pipe 4 is pushed to the center by the alignment component 5 to align the ports of the anti-corrosion steel pipe 4. Finally, the cutting component 6 cuts the ports of the anti-corrosion steel pipe 4 in batches.

[0045] After the anti-corrosion steel pipe 4 is positioned, the first clamping roller 310 is driven to rotate by the second driving motor 311, so that the first clamping roller 310 can drive the anti-corrosion steel pipe 4 to rotate.

[0046] Preferably, the number ratio of the clamping groove 39, the first clamping roller 310, the second driving motor 311, the support plate 314 and the second clamping roller 315 is 1:1:1:1:2, and the positions correspond to each other.

A roller groove 312 is opened in the middle of the pipe clamping column plate 35, and the roller groove 312 is adapted to the first clamping roller 310, leaving room for the first clamping roller 310 to move, so as to avoid structural interference between the pipe clamping column plate 35 and the first clamping roller 310 when rotating. The support plate 314 is set to an arc structure adapted to the anti-corrosion steel pipe 4.

[0047] For further example 2, please refer to Figure 6 to Figure 7 As shown:

[0048] The alignment component 5 includes a driving mechanism 51 and two alignment push plates 52. The driving mechanism 51 is used to drive the two alignment push plates 52 to move toward or away from each other. The opposite sides of the two alignment push plates 52 are rotatably connected with turntables 53. The number of turntables 53 is equal to the number of anti-corrosion steel pipes 4. After the anti-corrosion steel pipes 4 are clamped by the batch clamping component 3, the anti-corrosion steel pipes 4 overlap with the axial center lines of the turntables 53. A through hole 54 is opened in the middle of the alignment push plate 52, and the drive shaft 34 passes through the through hole 54.

[0049] Preferably, the driving mechanism 51 includes a driving motor 511, a counter-rotating threaded rod 512, a limiting rod 513 and two transmission frames 514. The driving motor 511 is fixedly installed on one side of the length direction of the processing table 1, and the counter-rotating threaded rod 512 and the limiting rod 513 are installed inside the processing table 1 for parallel rotation. The output end of the driving motor 511 is fixedly connected to one end of the transmission frame 514, and the two transmission frames 514 are symmetrically arranged on the counter-rotating threaded rod 512 and the limiting rod 513. One side of the transmission frame 514 is threadedly connected to the counter-rotating threaded rod 512, and the other side is slidably sleeved on the outer surface of the limiting rod 513. The spacing between the counter-rotating threaded rod 512 and the limiting rod 513 is greater than the diameter length of the anti-corrosion steel pipe 4, and the middle parts of the two transmission frames 514 are respectively fixedly connected to the two alignment push plates 52.

[0050] Specifically, by driving the counter-directional threaded rod 512 to rotate through the driving motor 511, the two transmission frames 514 can be moved toward or away from each other, wherein the limit rod 513 guides and limits the transmission frame 514, thereby driving the turntables 53 on the two alignment push plates 52 to align the ports of multiple anti-corrosion steel pipes 4.

[0051] The rotating disk 53 can rotate along with the anti-corrosion steel pipe 4 , thereby reducing the wear on the end of the anti-corrosion steel pipe 4 .

[0052] For further example 3, please refer to Figures 6 to 8 As shown:

[0053] The cutting assembly 6 includes an electric telescopic rod 61, which is fixedly mounted on the alignment push plate 52. The telescopic end of the electric telescopic rod 61 is fixedly connected to a ring frame 62, on which cutting knives 63 corresponding to the anti-corrosion steel pipe 4 are evenly arranged.

[0054] Among them, the cutting knife 63 can be set tangentially according to needs to facilitate cutting and peeling of the anti-corrosion layer of the anti-corrosion steel pipe 4.

[0055] Preferably, the cutting assembly 6 also includes a leveling mechanism 64 corresponding to the cutting knife 1 63, and the cutting knife 1 63 is located between the leveling mechanism 64 and the alignment push plate 52. The leveling mechanism 64 includes a sliding rod 641 fixedly installed on the inner side of the ring frame 62, and a knife holder 642 is slidably sleeved on the sliding rod 641. A spring 643 is arranged between the knife holder 642 and the ring frame 62, and a cutting knife 2 644 is detachably installed on the knife holder 642.

[0056] Preferably, the side of the cutting knife 644 that cuts the anti-corrosion layer of the anti-corrosion steel pipe 4 is a sloped structure. The cutting knife 644 is squeezed by the anti-corrosion steel pipe 4 so that the cutting knife 644 can be pressed against the surface of the anti-corrosion layer of the anti-corrosion steel pipe 4, and the tool holder 642 compresses the spring 643.

[0057] Specifically, after the anti-corrosion steel pipe 4 is aligned with the turntable 53, the anti-corrosion steel pipe 4 rotates, so that the cutting knife 63 automatically cuts the anti-corrosion layer of the anti-corrosion steel pipe 4. At the same time, the electric telescopic rod 61 is controlled to gradually extend according to the required cutting distance, so that the cutting knife 63 cuts to the required position.

[0058] Among them, during the cutting process by cutting knife 1 63, the anti-corrosion layer is subjected to the relatively unstable tearing force generated by cutting knife 1 63, which may cause burrs on the edge of the anti-corrosion layer near the specified cutting range, affecting the cutting effect. At this time, the pressure of spring 643 is used to press cutting knife 2 644 against the surface of the anti-corrosion layer, so that when cutting knife 1 63 cuts and tears the anti-corrosion layer, cutting knife 2 644 has a cutting restriction effect on its edge, thereby preventing the tearing effect generated by cutting knife 1 63 from spreading to the anti-corrosion layer outside the specified range, and at the same time, making the edge of the anti-corrosion layer after cutting more neat.

[0059] For further example 4, please refer to Figures 9 and 10 As shown:

[0060] The flip assembly 37 includes a driving frame 2 371 fixedly mounted on the top surface of the processing table 1, a driving motor 372 is fixedly mounted on the top of the driving frame 2 371, a spur gear 373 is fixedly connected to the output end of the driving motor 372, a notched tooth ring 374 is fixedly mounted on the outer side of the limiting ring plate 36, the notched tooth ring 374 is meshed with the spur gear 373, and the notched tooth ring 374 is meshed with the spur gear 373 by meshing and rotating the notched tooth ring 374, so that the clamping port 38 can be rotated vertically downward.

[0061] Preferably, a discharge assembly 7 is further included below the limiting ring plate 36, the discharge assembly 7 includes a guide plate 71 fixedly mounted in the middle of the top surface of the processing table 1, a guide groove 72 is provided in the middle of the processing table 1, a discharge slide 73 is fixedly mounted on the bottom of the processing table 1, and friction layers 74 are symmetrically mounted on both sides of the guide groove 72 in the width direction.

[0062] Preferably, the top of the guide plate 71 is an arc-shaped structure with an opening facing upward, and the anti-corrosion steel pipe 4 can roll down along the guide plate 71, the guide groove 72, and the unloading slide 73 in sequence. The friction layer 74 is made of rubber, and the opposing surfaces of the two friction layers 74 are serrated.

[0063] Specifically, through the existing controller and programming technology, after the cutting process is completed, the drive motor 1 33 and the drive motor 3 372 drive the clamping column disc 35 and the limit ring plate 36 to rotate synchronously until the clamping port 38 is vertically downward. Then, the clamping column disc 35 continues to rotate, so that the anti-corrosion steel pipe 4 in the clamping groove 39 falls from the clamping port 38 in turn, and is unloaded through the guide plate 71, the guide groove 72, and the unloading slide 73 in turn. At the same time, a conveying device can be set at the outlet of the unloading slide 73 to transport the processed anti-corrosion steel pipe 4 to the subsequent process.

[0064] Among them, through the setting of the friction layer 74, the fall of the anti-corrosion steel pipe 4 can be buffered and protected, thereby preventing the anti-corrosion steel pipe 4 from being damaged and deformed.

[0065] Everything in the above example works like this:

[0066] When in use, the anti-corrosion steel pipe 4 is placed in the clamping groove 39 from the clamping opening 38, and then the driving motor 33 drives the driving shaft 34 to rotate so that the next clamping groove 39 is aligned with the clamping opening 38, and the operation is repeated until the anti-corrosion steel pipe 4 is filled with the corresponding clamping grooves 39, and then the clamping column plate 35 is deflected by a certain angle so that each first clamping roller 310 is aligned with the clamping groove 39, and then the telescopic cylinder 313 is extended so that the anti-corrosion steel pipe 4 is positioned at three points by the second clamping roller 315 and the first clamping roller 310, and then the driving motor 4 511 drives the different-direction threaded rod 512 to rotate, driving the two alignment push plates 52 to move. The turntable 53 aligns the ports of multiple anti-corrosion steel pipes 4, and drives the anti-corrosion steel pipes 4 to rotate through the first clamping roller 310. At the same time, the electric telescopic rod 61 is controlled to gradually extend according to the required cutting distance, so that the cutting knife 63 cuts to the required position. After the processing is completed, the clamping port 38 is rotated to vertically downward, and then the clamping column plate 35 continues to rotate, so that the anti-corrosion steel pipes 4 in the clamping groove 39 fall from the clamping port 38 in turn, and are unloaded through the guide plate 71, the guide groove 72, and the unloading slide 73 in turn. At the same time, a conveying device can be set at the outlet of the unloading slide 73 to transport the processed anti-corrosion steel pipes 4 to the subsequent process.
