Therefore, they are more uniform and stable in structure, can withstand higher pressures and stresses, have higher physical properties, and are particularly suitable for applications in extreme environments.

[0014] Beneficial effects:

[0015] 1. The present invention realizes that both the seamless round pipe and seamless square pipe to be cut can be supported through the cooperation of the blanking bar group and the limiting bar to keep the cutting stable. After cutting, the cut seamless round pipe or seamless square pipe can be obliquely guided downward and stacked through the obliquely arranged blanking bar group, eliminating the need for manual picking and stacking of the cut seamless round pipe or seamless square pipe, thereby improving production efficiency;

[0016] 2. The seamless circular tubes rolling along the blanking bar group are intercepted and buffered by the interception component, avoiding the gradual increase in the rolling speed of the seamless circular tubes on the blanking bar group and finally quickly rushing down the blanking bar group;

[0017] 3. By dividing the blanking bar group into a guiding bar and a moving bar, while the cut seamless square tubes slide obliquely downward along the blanking bar group, the moving bar translates back and forth relative to the guiding bar. The moving bar pushes the seamless square tubes to move obliquely downward to the left along the guiding bar, enabling them to fall smoothly and avoiding jamming on the blanking bar group. At the same time, several rubber sheets are arranged on the moving bar, and the included angle between the rubber sheets and the moving bar is 10 - 15 degrees. When the seamless square tubes move, the rubber sheets are pressed into the corresponding accommodation grooves on the moving bar. After passing over the rubber sheets, the left side of the rubber sheets will contact the right side of the seamless square tubes, thereby pushing the seamless square tubes to slide and preventing the seamless square tubes from retreating when the moving bar moves to the right;

[0018] 4. Extension pieces are arranged on the lower sides of the ends of all the guiding bars and moving bars of the blanking bar group, increasing the contact surface between the end of the blanking bar group and the seamless circular tubes, limiting the fallen seamless circular tubes, preventing them from rolling to the right, and avoiding the seamless circular tubes that have fallen from rolling to the right on the surface of the supporting plate due to inertia, occupying the placement position of the next seamless circular tube and affecting the palletizing; and through the movement of the blanking bar group, the seamless circular tubes or seamless square tubes that have fallen onto the supporting plate are pushed to lean closely to the left, ensuring the overall stability of the seamless circular tubes or seamless square tubes after palletizing.

[0032] The moving component includes: a first guide rail 101 and a first electric slider 102; two inclined first guide rails 101 are fixedly connected to the workbench 1, and the inclination angle of the first guide rail 101 is the same as that of the blanking strip group 3; a first electric slider 102 is slidably connected to each first guide rail 101; all the first electric sliders 102 are fixedly connected to the connecting block 2 together.

[0033] The collecting component includes: a second electric telescopic rod 8, a connecting frame 81, and a supporting plate 012; four second electric telescopic rods 8 are bolted to the lower side of the workbench 1; the telescopic ends of all the second electric telescopic rods 8 are fixedly connected to a connecting frame 81, and a supporting plate 012 is slidably connected to the connecting frame 81; the supporting plate 012 is located below the blanking strip group 3.

[0034] The intercepting and buffering component includes: a second guide rail 103, a second electric slider 104, and an intercepting strip 201; two second guide rails 103 are bolted to the workbench 1; a second electric slider 104 is slidably connected to each second guide rail 103; all the second electric sliders 104 are fixedly connected to eight intercepting strips 201 together; the intercepting strips 201 are arranged alternately with all the guiding strips 31 and moving strips 32 of the blanking strip group 3.

[0035] The blanking strip group 3 further includes an extension piece 33; an extension piece 33 is fixedly connected to one end of each guiding strip 31 and moving strip 32 away from the connecting block 2; used to increase the contact area between the end of the guiding strip 31 and moving strip 32 away from the connecting block 2 and the seamless steel pipe.

[0036] The blanking strip group 3 further includes rubber sheets 34; several rubber sheets 34 are fixedly connected to each moving strip 32; the included angle between the rubber sheet 34 and the moving strip 32 is 10-15 degrees; a receiving groove for the rubber sheet 34 is correspondingly arranged on the moving strip 32.

[0037] A waste discharge opening 12 is formed on the workbench 1; the waste discharge opening 12 is located directly below the seamless steel pipe cutting area, and the chips fall through the waste discharge opening 12 to avoid accumulation on the surface of the workbench 1.

[0038] A support roller 11 is rotatably connected to the workbench 1; the support roller 11 is in contact with the bottom of the blanking strip group 3 to support the blanking strip group 3 and improve stability.

[0039] Taking Figure 1 as a reference, the side where the second electric telescopic rod 8 is located is the left side, the side where the first guide rail 101 is located is the right side, the side of the blanking strip group 3 close to the connecting block 2 is the top end, and the side close to the supporting plate 012 is the end; in the initial state of the present invention, the end of the blanking strip group 3 is close to the left side of the supporting plate 012.

[0040] The using steps of the high-performance seamless steel pipe intelligent production device of the present invention are as follows:

[0041] Convey the seamless steel pipe to be cut through the pipe conveyor so that it passes through the electric chuck 011. When the seamless steel pipe passes through the electric chuck 011 and reaches the required cutting length, control the electric chuck 011 to clamp the seamless steel pipe. As Figure 1 shown, at this time, the bottom of the seamless steel pipe passing through the electric chuck 011 is supported by the blanking strip group 3 and the limiting strip 4, and the included angle formed by the blanking strip group 3 and the limiting strip 4 is used to limit the seamless steel pipe to be cut to prevent it from moving during cutting and after cutting. Then control the electric cutting machine 010 to work, and at the same time, the electric lifting frame drives the electric cutting machine 010 to move down to cut the seamless steel pipe. After the seamless steel pipe is cut off, the electric lifting frame drives the electric cutting machine 010 to move up and reset. Then taking Figure 3 as a reference, the motor 5 drives the limiting strip 4 to rotate counterclockwise with the connecting shaft 41 as the rotation point. The limiting strip 4 flips downward and is lower than the blanking strip group 3, releasing the support and limit on the left side of the seamless steel pipe. The cut seamless steel pipe will roll obliquely downward to the left along the blanking strip group 3 and finally fall on the supporting plate 012. After the cut seamless steel pipe falls, control the first electric slider 102 to move to the right along the first guide rail 101, driving the connecting block 2 and the blanking strip group 3 to move to the right, so that a distance capable of accommodating a new seamless steel pipe is vacated between the end of the blanking strip group 3 and the seamless steel pipe on the supporting plate 012. Then continue to cut the remaining seamless steel pipes in the same way as above, and under the guidance of the blanking strip group 3, the cut seamless steel pipes will roll obliquely downward and fall on the supporting plate 012 in turn, and stacking is carried out from left to right in sequence.

[0042] It should be noted that the blanking strip group 3 moves obliquely upward to the right. For each distance it moves to the right, the distance between the end of the blanking strip group 3 and the upper surface of the supporting plate 012 will increase. Therefore, each time the blanking strip group 3 moves to the right, the electric telescopic rod two 8 is synchronously controlled to drive the supporting plate 012 to move upward, ensuring that the distance between the end of the blanking strip group 3 and the upper surface of the supporting plate 012 remains unchanged. This avoids a large drop when the cut seamless steel pipe falls from the blanking strip group 3. After falling on the supporting plate 012, it will not shift in position, thus affecting the stacking.

[0043] The seamless steel pipe described in the above steps is a round pipe. However, seamless steel pipes also have a square pipe form. When the present invention cuts a seamless square pipe, as Figure 4 shown, the blanking strip group 3 and the limiting strip 4 can also support and limit the seamless square pipe. The cut seamless square pipe also slides obliquely downward along the inclined blanking strip group 3 to the supporting plate 012 for stacking. It should be understood that the inclination angle of the blanking strip group 3 is small (the angle between the blanking strip group 3 and the table surface of the workbench 1 should be less than thirty degrees). When the seamless square pipe slides along the blanking strip group 3, it will not roll over and thus will not shift.

[0044] After a layer of cut seamless steel pipes is stacked on the supporting plate 012 (according to the diameter of the seamless steel pipe and the surface area of the supporting plate 012, it can be obtained how many seamless steel pipes can be placed on the supporting plate 012 as one layer, and thus the driving element is programmed and controlled), the electric telescopic rod two 8 is controlled to contract to drive the supporting plate 012 to move downward, so that the vertex of the first layer of seamless steel pipes is at the same height as the original upper surface of the supporting plate 012. The subsequent cut seamless steel pipes will be stacked on the first layer of seamless steel pipes, thus carrying out stacking; it should be noted that when the seamless round pipes are stacked in multiple layers, the upper seamless round pipes will be correspondingly placed in the depressions formed between adjacent round pipes in the lower layer. Thus, the stacking of the seamless round pipes will be in a pyramid shape for stacking, avoiding movement. And the four sides of the supporting plate 012 are provided with raised edges to prevent the seamless round pipes stacked at the bottom layer from rolling.

[0045] Further, if the seamless steel pipe is a square pipe, when the seamless steel pipe slides obliquely downward along the blanking strip group 3, although the contact area between the blanking strip group 3 and the bottom surface of the seamless square pipe is small and the frictional resistance is small, in order to prevent the seamless square pipe from rolling on the blanking strip group 3, the inclination angle of the blanking strip group 3 is small, and it is inevitable that the seamless square pipe will get stuck on the blanking strip group 3 and cannot slide obliquely downward smoothly. Therefore, the present invention divides the blanking strip group 3 into a guiding strip 31 and a moving strip 32. While the cut seamless square pipe slides obliquely downward along the blanking strip group 3, the electric telescopic rod 6 is controlled to repeatedly extend and retract, thereby driving the connecting strip 7 and the moving strip 32 to move left and right back and forth repeatedly, so that the moving strip 32 translates back and forth relative to the guiding strip 31. The moving strip 32 contacts the bottom surface of the seamless square pipe. When the moving strip 32 moves to the left, the frictional force with the bottom surface of the seamless square pipe causes it to slide obliquely downward to the left. Since both the guiding strip 31 and the moving strip 32 are inclined, when the seamless square pipe moves to the right, it also needs to overcome the upward resistance, and thus a stronger thrust is required. Therefore, the moving strip 32 is used to push the seamless square pipe to slide obliquely downward to the left along the guiding strip 31, so that it can fall smoothly and avoid getting stuck on the blanking strip group 3.

[0046] Furthermore, when the seamless steel pipe is a round pipe, after falling from the blanking strip group 3 onto the supporting plate 012, it is likely to roll to the right on the surface of the supporting plate 012 due to the inertia after falling. At the same time, as the supporting plate 012 moves upward, the seamless round pipe on the supporting plate 012 may also roll, occupying the placement position of the next seamless round pipe and affecting the stacking. Therefore, extension pieces 33 are provided on the lower sides of the ends of all the guiding strips 31 and moving strips 32 of the blanking strip group 3, increasing the contact surface between the end of the blanking strip group 3 and the seamless round pipe, and at the same time limiting the falling seamless round pipe to prevent it from rolling to the right. After waiting for 3 - 5 seconds, when the falling seamless round pipe is stable on the supporting plate 012, then control the blanking strip group 3 to move to the right and the supporting plate 012 to rise, leaving the placement position of the next seamless round pipe empty, thereby avoiding the seamless round pipe after falling from rolling to the right on the surface of the supporting plate 012 due to inertia, occupying the placement position of the next seamless round pipe, and affecting the stacking. In addition, after the seamless square pipe falls onto the supporting plate 012, the blanking strip group 3 can also be moved to the left, and the extension piece 33 pushes the falling seamless square pipe to the left, so that the falling seamless square pipe moves to the left and abuts closely against the previously fallen seamless square pipe, ensuring the overall stability of the seamless square pipes after stacking.

[0047] The limiting strip 4 flips downward to release the restriction on the seamless round tube, so that the seamless round tube rolls obliquely downward along the blanking strip group 3. The limiting strip 4 will change from an oblique upward state to an oblique downward state during the flipping process. At this time, the seamless round tube is easy to roll over the limiting strip 4, and then fall from the limiting strip 4 to the blanking strip group 3, causing the seamless round tube to have a large initial rolling velocity. When it is finally transferred from the blanking strip group 3 to the supporting plate 012, it has a large inertia and rushes out of the predetermined placement position on the supporting plate 012, affecting the stacking arrangement. Furthermore, an interception buffer component is provided. After the limiting strip 4 releases the seamless round tube, the seamless round tube with a large initial velocity will be intercepted by the interception strip 201 after rolling along the blanking strip group 3 for a distance, so that the rolling seamless round tube is buffered. The electric slider 104 is then controlled to move the intercepting bar 201 downward along the guide rail 103 to release the interception of the seamless round tube, so that it continues to roll along the material strip group 3, and then the electric slider 104 is re-controlled to drive the intercepting bar 201 to move upward to intercept and buffer the next seamless round tube. It should be understood that when the seamless square tube slides along the material strip group 3, the intercepting bar 201 is controlled to move downward so that it does not intercept the seamless square tube, thereby preventing the seamless square tube from stopping on the material strip group 3 and being unable to move.

[0048] Since there is an oxide layer on the surface of the seamless square tube, its surface is rough, and when sliding along the guide strip 31 and the moving strip 32, the friction resistance is large. In order to ensure that the moving strip 32 pushes the seamless square tube to slide smoothly along the guide strip 31, and at the same time prevent the moving strip 32 from moving to the right and driving the seamless square tube, causing it to retreat to the right, such as Figure 5 As shown, a plurality of rubber sheets 34 are provided on the moving bar 32, and the angle between the rubber sheets 34 and the moving bar 32 is 10-20 degrees. When the seamless square tube slides along the moving bar 32, the seamless square tube forces the rubber sheets 34 to deform downward, so that the rubber sheets 34 are received in the corresponding receiving grooves on the moving bar 32. When the seamless square tube passes over the rubber sheets 34, the rubber sheets 34 are lifted up again. At the same time, as the moving bar 32 moves to the left, the left side of the rubber sheets 34 will contact the right side of the seamless square tube, thereby pushing the seamless square tube to slide to the left, so that it can continue to slide to the left on the guide bar 31 smoothly until it falls on the support plate 012, so as to ensure that the seamless square tube is smoothly moved to the support plate 012 along the blanking bar group 3, and avoid the seamless square tube being driven back to the right when the moving bar 32 moves to the right.

[0049] When the seamless steel pipes on the supporting plate 012 are palletized to the specified quantity and cannot be palletized continuously, the user inserts a forklift between the supporting plate 012 and the connecting frame 81, holds the supporting plate 012, and then transfers the supporting plate 012 and the palletized seamless steel pipes thereon by the forklift. After that, another empty supporting plate 012 is slid and installed on the connecting frame 81 manually, and the seamless steel pipes are continuously palletized and collected.

[0050] According to the above steps, we can know that the present invention has the following effects:

[0051] For seamless round pipes and seamless square pipes to be cut, they can be supported by the cooperation of the blanking strip group 3 and the limiting strip 4 to keep the cutting stable. After cutting, the cut seamless round pipes or seamless square pipes can be guided obliquely downward by the obliquely arranged blanking strip group 3 and palletized onto the supporting plate 012, without the need for manual picking and palletizing of the cut seamless round pipes or seamless square pipes, improving production efficiency. And during the process, the intercepting and buffering assembly buffers the seamless round pipes rolling along the blanking strip group 3 to avoid the rolling speed of the seamless round pipes on the blanking strip group 3 increasing gradually and finally rushing down the blanking strip group 3 quickly; the moving strip 32 and the rubber sheet 34 reciprocate relative to the guiding strip 31 to push the seamless square pipes on the guiding strip 31 to slide leftward, so as to ensure that the seamless square pipes smoothly move along the blanking strip group 3 to the supporting plate 012 and avoid the seamless square pipes moving backward to the right when the moving strip 32 moves rightward.

[0052] The additional technical effects of the present invention are as follows:

[0053] As Figure 1 shown, there is a gap between the blanking strip group 3 and the limiting strip 4, and the chips generated by cutting the seamless steel pipes will fall through the gap and will not remain on the blanking strip group 3, avoiding hindering the movement of the seamless steel pipes. At the same time, a waste discharge port 12 is opened on the workbench 1, and the fallen chips will fall through the waste discharge port 12. The user can place a collection container below the waste discharge port 12 for convenient centralized collection of the chips.

[0054] As Figure 2 shown, a support roller 11 is rotatably connected to the workbench 1; the support roller 11 contacts the bottom of the blanking strip group 3 to support the blanking strip group 3 and improve stability.

[0055] Embodiment 2

[0056] On the basis of Embodiment 1, as Figures 1-3 , Figure 7 and Figure 8As shown in the figure, the intelligent production device further includes an electric push rod 105, a push plate 202, a jet nozzle 203, a collection box 204, and an interception net 205; two electric push rods 105 are fixedly connected to the workbench 1; a push plate 202 is fixedly connected to the telescopic end of each electric push rod 105; eight jet nozzles 203 are installed on one push plate 202; the jet nozzles 203 are externally connected to an air pump through a quick-release pipe; a collection box 204 is communicated with the other push plate 202; the collection box 204 is of a through type at both ends; the inlet of the collection box 204 faces the jet nozzles 203; an interception net 205 is arranged at the outlet of the collection box 204.

[0057] The lower sides of the two push plates 202 are both inclined, and the inclination angle and inclination direction of the lower side of the push plate 202 are the same as those of the blanking strip group 3.

[0058] The collection box 204 is detachably connected to the corresponding push plate 202, which is convenient for the user to remove the chips collected in the collection box 204.

[0059] When using the present invention to cut and stack seamless steel pipes, the following problems will also be encountered:

[0060] When cutting seamless steel pipes, some chips will enter the inside of the seamless steel pipes. When the cut seamless steel pipes fall from the blanking strip group 3 onto the supporting plate 012, the chips inside will inevitably fall out and finally fall on the supporting plate 012. After multiple stackings, a large amount of chips will fall on the supporting plate 012. When the subsequent seamless steel pipes fall on the supporting plate 012, the seamless steel pipes will press on the chips and cause position deviation, affecting the overall stacking accuracy.

[0061] Before using the present invention, an external air pump is connected to the jet nozzles 203 through a pipe for air supply.

[0062] When the seamless steel pipe moves obliquely downward along the blanking strip group 3 and is temporarily blocked by the interception strip 201, first control the electric push rod 105 to extend, and the two push plates 202 will approach each other to clamp the seamless steel pipe. The two push plates 202 are respectively in contact with the two cutting surfaces of the seamless steel pipe to close the internal space of the seamless steel pipe. Then control the external air pump to work, supply air to the jet nozzles 203 through the pipe, and the jet nozzles 203 blow air into the seamless steel pipe to blow the chips in the seamless steel pipe into the collection box 204 on the other push plate 202. The chips are intercepted by the interception net 205 and collected in the collection box 204, and the blown air passes through the interception net 205 and blows out of the collection box 204. Subsequently, the user can regularly clean the chips in the collection box 204; after cleaning the chips in the seamless steel pipe, control the electric slider two 104 to drive the interception strip 201 to move downward along the guide rail two 103 to release the block on the seamless steel pipe. Then control the electric push rod 105 to contract, and the two push plates 202 release the clamp on the seamless steel pipe. The seamless steel pipe will continue to move obliquely downward along the blanking strip group 3 and fall onto the supporting plate 012 for stacking.

[0063] In addition, after the seamless steel pipe is temporarily intercepted by the interception bar 201, the seamless steel pipe is pushed and clamped from both sides simultaneously by two push plates 202, so as to position the seamless steel pipe sliding on the blanking bar group 3, and keep the seamless steel pipe horizontal relative to the blanking bar group 3, avoiding the position deviation of the seamless steel pipe relative to the blanking bar group 3 when the seamless steel pipe slides along the blanking bar group 3, and avoiding the position deviation of the seamless steel pipe falling onto the supporting plate 012, and improving the overall palletizing accuracy.

[0064] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
