Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe cutting, and specifically, to a device and method for synchronously cutting multiple steel pipes. Background Art

[0002] Currently, in the steel pipe processing industry, synchronously cutting multiple steel pipes is a common process, aiming to improve production efficiency and ensure that the lengths of the cut steel pipes are consistent to meet subsequent processing or usage requirements. However, in existing devices for synchronously cutting multiple steel pipes, there are still some technical problems, especially when dealing with steel pipes to be cut with different lengths.

[0003] After retrieval, it is found that a Chinese patent with the authorization announcement number CN211889212U discloses a pipe cutting device for stainless steel pipe production. This patent includes a frame body, a fixing mechanism, and a cutting mechanism. The device aligns and fixes the two ends of the steel pipe through the fixing mechanism, and adjusts the position of the cutting mechanism by a sliding seat to achieve precise cutting. This device can simultaneously fix and cut multiple steel pipes, improving the cutting efficiency. However, the degree of automation of this patent is low, and it cannot operate on multiple steel pipes synchronously. When it is necessary to synchronously cut multiple steel pipes with different lengths, a key problem is how to effectively align and position one end of the steel pipe before cutting. Since the lengths of the steel pipes are different, if cutting is directly performed, even if the cutting device itself has high precision, the lengths of the cut steel pipes may still not be unified, which will seriously affect the quality of subsequent processing and the usage effect. Traditional alignment and positioning methods often rely on manual operations, that is, workers observe with the naked eye and manually adjust to align one end of the steel pipe. This method is not only inefficient, but also difficult to guarantee the alignment accuracy. Especially in the case of processing a large number of steel pipes, the manual alignment method not only takes time and effort, but also easily introduces human errors, resulting in poor alignment effects. In addition, the fixing mechanism of this patent is relatively single in design and function, lacking an effective alignment and positioning mechanism for steel pipes with different lengths. This makes it necessary for workers to spend extra time and effort on alignment adjustment during actual operation, thereby reducing the overall production efficiency. Summary of the Invention

After the feeding assembly pushes the steel pipe into the placement plate, the positioning assembly aligns one end of several steel pipes with different lengths by extrusion and then cuts them.

[0038] The present invention also discloses a method for synchronously cutting multiple steel pipes. Using the above-mentioned device for synchronously cutting multiple steel pipes, it includes the following steps:

[0039] S1. Place several steel pipes in each of the storage assemblies respectively, and start the linear movement assembly to drive the placement plate to move on the working platform towards the cutting component;

[0040] S2, the placement plate passes through the bottom of the storage assembly during the movement, and the placement plate pushes a single steel pipe in the storage assembly into the corresponding placement plate through the loading assembly on one side when passing through the bottom of the storage assembly;

[0041] S3, the placing plates with steel pipes placed inside continue to move until the corresponding positioning assembly 1 extends into the placing plate and squeezes the axial direction of the steel pipe in the placing plate, and one end of the steel pipe in each placing plate is pressed against the side of the corresponding placing plate away from the positioning assembly 1 through the squeezing of the positioning assembly 1;

[0042] S4. After one end of all the steel pipes are squeezed, they are in the same straight line, and finally all the steel pipes are cut by the cutting disc. After cutting, the original steel pipes of different lengths are unified in length.

[0043] By adopting the above technical solution, the present invention has the following beneficial effects:

[0044] The steel pipes are stored in the storage box by setting up structures such as the push plate and the storage box. When the push plate moves with the placement plate and passes through the bottom of the storage box, the push plate enters the interior of the storage box from the push port of the storage box to push the single steel pipe to move. The pushed steel pipe is taken out from the discharge port of the storage box and then falls into the placement plate. After pushing the single steel pipe, the push plate is squeezed down by the steel pipe above. After the pushed out steel pipe is cut off, the push plate resets together with the placement plate and carries out the next round of automatic loading, thereby improving the overall automation level of the equipment.

[0045] Through the arrangement of structures such as the placement plate and the positioning plate, the placement plate with the steel pipes placed thereon continues to move on the working platform, and the positioning plate continues to move and extends into the open part of the placement plate, thereby squeezing the axial direction of the steel pipe in the placement plate. The squeezed steel pipe rests on the closed part of the placement plate, and finally one end of all the steel pipes to be cut are in the same straight line, and then all the steel pipes are uniformly cut to obtain a number of equal-length steel pipes that meet the standards.

[0046] Through the setting of the placement plate and the positioning plate 2 structures, the diameters of each batch of steel pipes are not exactly the same. When placed in the placement plate, they are prone to shaking in the placement plate, which leads to unstable subsequent cutting. Therefore, when the positioning plate 2 moves toward the cutting part following the placement plate, it is squeezed by the squeezing plate on the working platform to achieve its own displacement, thereby positioning the steel pipes in the placement plate. At the same time, a contraction spring 4 is arranged on the positioning plate 2, which can achieve the effect of self-adaptation according to steel pipes of different diameters.

[0047] Through the settings of three structures including a placement plate and a positioning plate, the placement plate is divided into a main placement plate, a connecting concave plate, and a secondary placement plate. The cutting disc moves from the connecting concave plate, dividing the steel pipe into two sections. The main placement plate contains the required steel pipe, and the secondary placement plate contains the excess part of the steel pipe. To further ensure the stability of cutting, when the placement plate moves towards the cutting component, it drives the two positioning plates at the main placement plate and the secondary placement plate to move, thereby squeezing and fixing the steel pipes in the main placement plate and the secondary placement plate in the longitudinal position, that is, fixing both sides of the cutting part of the steel pipe, so as to achieve a more stable cutting effect.

[0048] Through the settings of structures such as a cutting disc and a deflecting plate, the cutting disc can achieve linear movement in the horizontal position driven by the third threaded rod. However, if the number of steel pipes to be cut is too large and the cutting disc works for a long time, the cutting quality will decline. Therefore, an additional deflecting plate is set. Based on the overall linear movement of the cutting disc, the deflecting plate adds an arc-shaped movement path to the cutting disc. The arc-shaped cutting path can make the cutting force more evenly distributed, thereby reducing local stress concentration and the risk of material deformation or cracking.

[0049] Through the settings of structures such as a blanking component and a placement plate, when the placement plate drives the two cut sections of the steel pipe to move towards the blanking component, they come into contact with the upper rack and the lower rack in the blanking component, causing the blanking plates one and two in the main placement plate and the secondary placement plate to rotate. The blanking plates one and two that originally supported the steel pipe drive the steel pipes on them to fall from the bottom of the placement plate into the containers for separately storing the two sections of the steel pipe.

[0092] A fourth compression spring 411 is connected to the other side of the middle plate 410, and the other end of the fourth compression spring 411 is connected to a second positioning plate 412. The two mating plates 47 are adapted to drive the corresponding middle plates 410 and second positioning plates 412 to exert extrusion positioning on the outer peripheral surface of the steel pipe in the main placing plate 24 after being extruded by the corresponding extrusion plates 45.

[0093] As Figure 9 、 Figure 11 shown, the positioning member 4 further includes a third positioning component. The third positioning component includes two third positioning plates 421 and a linkage mechanism corresponding to the third positioning plates 421. The two third positioning plates 421 are respectively located above the main placing plate 24 and the sub - placing plate 26. The linkage mechanism is adapted to be connected to the corresponding third positioning plates 421 to drive the third positioning plates 421 to exert pressure on the longitudinal direction of the steel pipe in the placing plate;

[0094] The linkage mechanism includes a second threaded rod 414, a moving sleeve 415 and a rotating sleeve 418. Two connecting plates 413 corresponding to the positions of the third positioning plates 421 are connected to one side of the working platform 2. The second threaded rod 414 is rotatably installed on the corresponding connecting plate 413. The moving sleeve 415 is assembled outside the second threaded rod 414. The rotating sleeve 418 is rotatably arranged outside the moving sleeve 415. The third positioning plate 421 is fixedly sleeved outside the corresponding rotating sleeve 418. An extension plate 422 is fixedly sleeved outside the moving sleeve 415. A second guide rod 423 is fixedly connected to the connecting plate 413. The extension plate 422 is adapted to slide on the outer peripheral surface of the second guide rod 423 when following the movement of the moving sleeve 415;

[0095] A first gear 416 is fixedly sleeved outside the moving sleeve 415 located at the main placing plate 24. A second gear 419 is fixedly sleeved outside the rotating sleeve 418 located at the main placing plate 24. A first rack 417 and a second rack 420 are connected to the corresponding sides of the main placing plate 24 and the first gear 416 and the second gear 419. The first rack 417 meshes with the first gear 416. The second rack 420 meshes with the second gear 419. The first rack 417 and the second rack 420 are adapted to drive the first gear 416 and the second gear 419 to rotate respectively when following the movement of the main placing plate 24 towards the cutting member 5;

[0096] A third gear 424 is fixedly sleeved outside the moving sleeve 415 located at the secondary placing plate 26. A fourth gear 425 is fixedly sleeved outside the rotating sleeve 418 located at the secondary placing plate 26. A third rack 426 and a fourth rack 427 are connected to the corresponding sides of the secondary placing plate 26 and the third gear 424 and the fourth gear 425. The third rack 426 meshes with the third gear 424. The fourth rack 427 meshes with the fourth gear 425. The third rack 426 and the fourth rack 427 are adapted to drive the third gear 424 and the fourth gear 425 to rotate respectively when following the movement of the secondary placing plate 26 towards the cutting member 5.

[0097] The working principle of this embodiment is as follows:

[0098] During use, several steel pipes are respectively placed in each storage box 11. The linear movement assembly is started to drive the placing plate to move on the working platform 2, so as to drive the feeding assembly 3 to take out one steel pipe from the corresponding storage box 11 and send it into the placing plate. After one steel pipe is placed in all the placing plates, it continues to move on the working platform 2. During the movement, the corresponding positioning assembly I axially presses the steel pipes in the corresponding placing plates, so that one end of all the steel pipes abuts against the closed part 210 of the placing plate, presenting that the same ends of all the steel pipes are on the same straight line. At this time, cutting with the cutting disc 515 can cut all the steel pipes into a unified length;

[0099] Specifically, the linear motor 21 is activated to drive the first threaded rod 28 to rotate, thereby driving the moving plate 27 to move linearly, and further driving the placement plate to move on the slide rail 23 of the working platform 2. The first threaded rod 28 and the moving plate 27 can be assembled through a ball nut. The realization of linear transmission by the threaded rod is an existing technology and will not be elaborated in detail here. A push plate 32 is provided on the working platform 2. When the push plate 32 follows the placement plate to move, it will pass through the bottom of the storage box 11. During this process, the push plate 32 enters through the pushing port 12 of the storage box 11 and applies a thrust to the bottommost steel pipe in the storage box 11. During continuous movement, the steel pipe is pushed out from the discharge port 13 and falls into the placement plate, thereby achieving the effect of automatic feeding. It should be noted that only the push plate 32 can pass through the pushing port 12, and the steel pipe can also pass through the discharge port 13. A limiting portion 14 is provided at the bottom of the storage box 11, and the steel pipes in the storage box 11 cannot fall from below the storage box 11 and can only be pushed out from the discharge port 13 by the drive of the push plate 32. When re-feeding is required, the placement plate needs to be reset, that is, the placement plate moves in the reverse direction on the working platform 2. At this time, the push plate 32 enters the storage box 11 from the discharge port 13 and contacts the new bottommost steel pipe. However, since the pushing port 12 cannot allow the steel pipe to pass through, the push plate 32 cannot push the steel pipe at this time. At this time, the steel pipe applies a pressure to the inclined portion at the top of the push plate 32. The stressed push plate 32 squeezes the first telescopic rod 33 and the first compression spring 34 downward and slides into the fixed plate 31, so as to enable the push plate 32 to normally pass through the storage box 11 to the other side of the storage box 11. After losing the extrusion of the steel pipe on the push plate 32, the push plate 32 is reset by the first telescopic rod 33 and the first compression spring 34. After resetting, the push plate 32 performs automatic feeding work again according to the above method;

[0100] After the push plate 32 pushes a single steel pipe into the placement plate, the placement plate continues to move on the working platform 2 towards the cutting component 5 under the drive of the first threaded rod 28. During the movement process, it will simultaneously drive the second positioning assembly, the third positioning assembly, and the first positioning assembly to position the steel pipe in the placement plate for subsequent cutting work. At the same time, the placement plate is divided into three parts: the main placement plate 24, the connecting concave plate 25, and the secondary placement plate 26. The position of the connecting concave plate 25 is lower than that of the main placement plate 24 and the secondary placement plate 26, resulting in a gap between the main placement plate 24 and the secondary placement plate 26. The cutting disc 515 cuts the steel pipe in this gap, dividing the steel pipe into two sections, one section is in the main placement plate 24 and the other section is in the secondary placement plate 26;

[0101] The way the placement plate moves to drive the second positioning component is that there are two symmetrically arranged mating plates 47 inside the placement plate, and there are two pressing plates 45 corresponding to the mating plates 47 on the working platform 2. When the placement plate moves towards the cutting component 5 after placing the steel pipe, the inclined surface 46 on the fixed pressing plate 45 will squeeze the inclined surface 48 on the mating plate 47, thereby pushing the mating plate 47 towards the inside of the placement plate. There is an intermediate plate 410 on the mating plate 47, and a third contraction spring 49 is arranged between the intermediate plate 410 and the inner wall of the placement plate. The third contraction spring 49 is used to stabilize the movement and reset of the mating plate 47. When both mating plates 47 are squeezed towards the inside of the placement plate, it can push the steel pipe inside the placement plate to make it centered, and at the same time, it can also provide a certain clamping force. In order to deal with steel pipes of various diameters, a fourth contraction spring 411 is arranged on the intermediate plate 410, and a second positioning plate 412 is arranged on the fourth contraction spring 411. The second positioning plate 412 contacts the outer peripheral surface of the steel pipe. The moving stroke of the mating plate 47 after being squeezed by the pressing plate 45 is limited. Therefore, the fourth contraction spring 411 and the second positioning plate 412 are arranged to prevent the intermediate plate 410 from not being able to act on the steel pipe with a smaller diameter. This setting improves the adaptability and can automatically adjust according to steel pipes of different diameters to ensure that the steel pipe in the placement plate can be centered, reduce shaking, and at the same time provide a certain clamping force to prepare for the subsequent cutting work;

[0102] At the same time, as the placement plate moves, the first positioning plate 44 extends into the opening part located at the secondary placement plate 26, and the axial direction of the steel pipe in the placement plate is squeezed through the opening part, so that the end of the steel pipe away from the first positioning plate 44 abuts against the closed part 210 of the placement plate. The components on each working platform 2 are the same. Therefore, the same ends of all the steel pipes in the placement plates will abut against their respective corresponding closed parts 210. At this time, the same ends of these steel pipes are on the same straight line. When the cutting disc 515 cuts all the steel pipes in a straight line at the connecting groove later, it can ensure that no matter whether the initial lengths of these steel pipes are equal or not, the lengths of the steel pipes remaining in the main placement plate 24 after cutting are unified and can meet the production requirements. The first positioning plate 44 is connected by the second telescopic rod 41 and the second contraction spring 43 to achieve the stable movement and reset of the first positioning plate 44. By the retractable way of the first positioning plate 44, steel pipes of different lengths can be squeezed. When all the placement plates move synchronously and the moving distances are the same, the steel pipe with a longer self-length is subjected to a greater squeezing force from the first positioning plate 44, and vice versa, the steel pipe with a shorter self-length is subjected to a smaller squeezing force from the first positioning plate 44. No matter the size of the squeezing force, it can ensure that the steel pipe is stably abutted against the corresponding closed part 210;

[0103] At the same time, during the movement of the placement plate, the rack three 426 and the rack four 427 located on the side of the auxiliary placement plate 26 will pass through the gear one 416 and the gear three 424, but the sizes do not match, so there will be no meshing. When the rack three 426 and the rack four 427 continue to follow the movement and come to the gear three 424 and the gear four 425, the rack one 417 and the rack two 420 located on the side of the main placement plate 24 also come to the position of the gear one 416 and the gear two 419, one to one, and mesh with their respective corresponding ones during the movement of the placement plate. 16 and the gear rack 417 are meshed to drive the rotating sleeve 418 located on one side of the main placement plate 24 to rotate on the movable sleeve 415. During the rotation, the positioning plate 3 421, which is initially parallel to the long side of the placement plate, is driven to rotate directly above the main placement plate 24. The initial position is parallel to the long side of the placement plate. In order to avoid the push plate 32 pushing the steel pipe to fall into the inside of the placement plate and causing interference, after the steel pipe enters the placement plate, the gear rack 417 drives the gear 416 to rotate so that the positioning plate 3 421 is rotated to the top of the main placement plate 24. Then, the rack 2 420 drives the gear 2 419 to rotate. When the gear 2 419 rotates, it drives the threaded rod 2 414 to rotate. When the rack 2 420 moves toward the cutting component 5, it drives the gear 2 419 to rotate forward, and then drives the threaded rod 2 414 to rotate forward, so that the movable sleeve 415 moves downward, and then drives the rotating sleeve 418 and the positioning plate 3 421 to move downward, and the steel pipe at the main placement plate 24 is squeezed and limited. In order to prevent the movable sleeve 415 from rotating under the drive of the threaded rod 2 414, a guide rod 3 53 is also provided. When the movable sleeve 415 moves, The extension plate 422 is driven to move, and the extension plate 422 slides on the guide rod three 53 to restrict the movable sleeve 415 so that the movable sleeve 415 can only move longitudinally and linearly, thereby realizing the restricted positioning of the steel pipe at the main placement plate 24, which is convenient for subsequent cutting work. When the cutting is completed, the placement plate moves in the opposite direction and drives the rack 1 417 and the rack 2 420 to move, and the rack 1 417 and the rack 2 420 respectively drive the gear 1 416 and the gear 2 419 to rotate, thereby realizing the overall reset of the positioning plate three 421 and releasing the restriction on the steel pipe;

[0104] The positioning plate three 421 located at the secondary placement plate 26 works in the same way as the positioning plate three 421 at the main placement plate 24. The positioning plate three 421 at the secondary placement plate 26 is used to position and restrict the steel pipes at the secondary placement plate 26. The only difference is that the widths of the rack three 426 and the rack four 427 are smaller than those of the rack one 417 and the rack two 420. Therefore, when the rack three 426 and the rack four 427 move to the gear one 416 and the gear two 419, they will not drive the gear one 416 and the gear two 419 to rotate. However, the gears of the gear three 424 and the gear four 425 corresponding to the rack three 426 and the rack four 427 are larger than the gear one 416 and the gear two 419. Therefore, the rack three 426 and the rack four 427 can drive the gear three 424 and the gear four 425 to rotate, thereby driving the positioning plate three 421 at the secondary placement plate 26 to work properly. It should be noted that the rack one 417, the rack two 420, the rack three 426, and the rack four 427 can all be replaced at will. The rack used to control the rotation of the rotating sleeve 418 can drive the positioning plate three 421 to rotate from a state parallel to the long side of the placement plate to a position above the placement plate. The rack used to control the movement of the moving sleeve 415 can be replaced according to the diameter of the steel pipe to be cut. The longer the rack, the more turns the gear used to control the moving stroke of the moving sleeve 415 rotates, and the greater the distance the moving sleeve 415 descends, so as to realize the positioning and restriction of steel pipes of different sizes;

[0105] The positioning plate one 44, the positioning plate two 412, and the positioning plate three 421 all work synchronously when moving further towards the cutting component 5 after the steel pipes are placed on the placement plate, simultaneously completing the multi-positioning and restriction of the axial, horizontal peripheral surface, and longitudinal peripheral surface of the steel pipes, improving the stability during subsequent cutting;

[0106] It should be noted that a waste chip groove is provided in each connecting groove. The waste chips generated when the cutting disc 515 cuts at the connecting concave plate 25 will fall into the waste chip groove, and subsequent operators can clean them up uniformly.

[0107] Embodiment 2: As Figure 14 shown, this embodiment further includes the following structure on the basis of Embodiment 1: The cutting-off device further includes a support frame 51, the driving component is arranged on the support frame 51, the driving component includes a driving motor 52 installed on the support frame 51, a threaded rod three 54 rotatably installed in the support frame 51, a guide rod three 53 fixedly connected in the support frame 51, a transmission sleeve one 55 assembled outside the threaded rod three 54, and a driving box 514;

[0108] The driving motor 52 is connected to the third threaded rod 54 so as to drive the third threaded rod 54 to rotate within the support frame 51, thereby driving the first transmission sleeve 55 to move along the axial direction of the third threaded rod 54. The first transmission sleeve 55 is connected to the driving box 514, and the driving box 514 is connected to the cutting disc 515 so as to drive the cutting disc 515 to rotate. The cutting disc 515 is located within the cutting chamber.

[0109] As Figure 15 shown, the driving assembly further includes a direction-changing mechanism. The direction-changing mechanism is adapted to connect the first transmission sleeve 55 and the driving box 514. The direction-changing mechanism includes a direction-changing plate 512, and the direction-changing plate 512 is connected to the bottom of the first transmission sleeve 55;

[0110] A housing 56 is connected to the bottom of the first transmission sleeve 55. A control motor 57 is installed on the housing 56. A fourth threaded rod 58 is rotatably installed within the housing 56. A second transmission sleeve 59 is assembled outside the fourth threaded rod 58. The control motor 57 is connected to the fourth threaded rod 58 so as to drive the fourth threaded rod 58 to rotate within the housing 56, thereby driving the second transmission sleeve 59 to move along the axial direction of the fourth threaded rod 58;

[0111] A rotating shaft 510 is fixedly connected within the second transmission sleeve 59. A connecting shaft 513 is fixedly connected to one side of the driving box 514. A direction-changing groove penetrating through itself is formed on the direction-changing plate 512. The direction-changing groove is arc-shaped. The connecting shaft 513 passes through the direction-changing groove and is slidably arranged within the direction-changing groove. An articulated rod 511 is arranged between the connecting shaft 513 and the rotating shaft 510. One end of the articulated rod 511 is movably sleeved on the outer circumferential surface of the connecting shaft 513, and the other end of the articulated rod 511 is movably sleeved on the outer circumferential surface of the rotating shaft 510. The second transmission sleeve 59 is adapted to drive the connecting shaft 513 and the driving box 514 to move along the trend of the direction-changing groove when being driven to move linearly, thereby driving the cutting disc 515 to move along the trend of the direction-changing groove.

[0112] The working principle of this embodiment is as follows:

[0113] After the steel pipes within the placing plate are multi-positioned and restricted by the positioning member 4, the driving box 514 is started to drive the cutting disc 515 to rotate. The driving box 514 includes a motor and a gearbox, which belongs to the prior art and will not be elaborated in detail here. After the cutting disc 515 rotates normally, the driving motor 52 is started to drive the third threaded rod 54 to rotate. The third threaded rod 54 rotates to drive the first transmission sleeve 55 to move linearly. At the same time, the first transmission sleeve 55 slides outside the third guide rod 53 to prevent the first transmission sleeve 55 from rotating by itself under the drive of the third threaded rod 54. When the first transmission sleeve 55 moves linearly, it can drive the driving box 514 to move linearly, thereby driving the cutting disc 515 to move linearly. The cutting disc 515 moves within the cutting chamber formed between the main placing plate 24, the secondary placing plate 26, and the connecting groove, synchronously cutting all the positioned steel pipes, improving the efficiency of the cutting work;

[0114] Since it is necessary to cut several steel pipes simultaneously, the wear on the cutting tool is relatively large, and it is impossible to ensure that the cutting quality of each steel pipe is the same. Therefore, a deflector plate 512 is provided between the drive box 514 and the first transmission sleeve 55 to change the cutting path of the cutting disc 515. During use, first, the first transmission sleeve 55 drives all the parts below it to move to the steel pipe to be cut. Then, the control motor 57 is started to drive the fourth threaded rod 58 to rotate. When the fourth threaded rod 58 rotates, it drives the second transmission sleeve 59 to move linearly. Part of the second transmission sleeve 59 is located in the groove of the housing 56 where the fourth threaded rod 58 is installed, which restricts the second transmission sleeve 59 to prevent self-rotation. A connecting shaft 513 is connected to the drive box 514. The connecting shaft 513 passes through the deflection groove of the deflector plate 512. A rotating shaft 510 is arranged in the second transmission sleeve 59. An articulated rod 511 is movably hinged between the rotating shaft 510 and the connecting shaft 513. When the second transmission sleeve 59 is driven to move, it synchronously drives the articulated rod 511 to move. The articulated rod 511 then drives the connecting shaft 513 to move along the trajectory of the deflection groove. The deflection groove is arranged in an arc shape, so as to drive the drive box 514 and the cutting disc 515 to move in an arc shape. The steel pipe to be cut is cut by the arc-shaped cutting method. When the second transmission sleeve 59 drives the connecting shaft 513 to complete the entire deflection groove, the cutting is completed. After completion, the second transmission sleeve 59 moves back to its original position under the reverse rotation of the fourth threaded rod 58, thereby driving the connecting shaft 513 to return to its original position, and further driving the cutting disc 515 to return to its original position. So far, the cutting work of a single steel pipe is completed. Subsequently, the first transmission sleeve 55 continues to drive the whole to move to the next steel pipe to be cut, and then the control motor 57 is started to drive the second transmission sleeve 59 to move, and then drive the cutting disc 515 to cut the steel pipe. Repeating this process can realize the cutting work of all steel pipes;

[0115] The setting of the deflector plate 512 is mainly to change the cutting form of the cutting disc 515 from a straight-line cutting form to an arc-shaped cutting form. The arc-shaped path can ensure that each steel pipe receives a uniform cutting force during cutting, which helps to improve the cutting quality, reduce deformation and damage during cutting, and at the same time can effectively disperse the stress generated during cutting, reduce local stress concentration, thereby reducing the risk of damage to the steel pipe during cutting. The arc-shaped cutting path can also better adapt to the circular contour of the steel pipe, reducing errors and unevenness caused by straight-line cutting.

[0116] Example 3: As Figures 12-13As shown in the figure, this embodiment further includes the following structure on the basis of Embodiment 1: The cutting device further includes a blanking assembly 6. The blanking assembly 6 includes a first blanking plate 61 disposed in the main placement plate 24, a second blanking plate 62 disposed in the secondary placement plate 26, a first rotating mechanism corresponding to the first blanking plate 61, and a second rotating mechanism corresponding to the second blanking plate 62. The first rotating mechanism is adapted to be connected to the first blanking plate 61 to drive the first blanking plate 61 to rotate downward in the main placement plate 24 towards the lower part of the main placement plate 24, and the second rotating mechanism is adapted to be connected to the second blanking plate 62 to drive the second blanking plate 62 to rotate upward in the secondary placement plate 26 towards the upper part of the secondary placement plate 26;

[0117] The first rotating mechanism includes two first vertical plates 63, a first rotating rod 64, and a first gear disk 65. The tops of the two first vertical plates 63 are connected to the bottom of the main placement plate 24. The first rotating rod 64 is rotatably installed inside the two first vertical plates 63. A part of the first rotating rod 64 extends out of the first vertical plates 63. Both the first gear disk 65 and the first blanking plate 61 are fixedly sleeved on the outer peripheral surface of the part of the first rotating rod 64 located between the two first vertical plates 63. A fifth contraction spring 66 is sleeved on the extending part of the first rotating rod 64. One end of the fifth contraction spring 66 is connected to the first rotating rod 64, and the other end of the fifth contraction spring 66 is connected to the first vertical plate 63. A lower rack 67 is connected in the through groove 22 of the working platform 2. The lower rack 67 meshes with the first gear disk 65. The first gear disk 65 is adapted to move towards the lower rack 67 following the main placement plate 24 and be driven to rotate by the lower rack 67;

[0118] The second rotating mechanism includes two second vertical plates 610, a second rotating rod 611, and a second gear disk 69. The tops of the two second vertical plates 610 are connected to the bottom of the secondary placement plate 26. The second rotating rod 611 is rotatably installed inside the two second vertical plates 610. A part of the second rotating rod 611 extends out of the second vertical plates 610. Both the second gear disk 69 and the second blanking plate 62 are fixedly sleeved on the outer peripheral surface of the part of the second rotating rod 611 located between the two second vertical plates 610. A sixth contraction spring 612 is sleeved on the extending part of the second rotating rod 611. One end of the sixth contraction spring 612 is connected to the second rotating rod 611, and the other end of the sixth contraction spring 612 is connected to the second vertical plate 610. An upper rack 68 is connected in the through groove 22 of the working platform 2. The upper rack 68 meshes with the second gear disk 69. The second gear disk 69 is adapted to move towards the upper rack 68 following the secondary placement plate 26 and be driven to rotate by the upper rack 68.

[0119] The working principle of this embodiment is as follows:

[0120] After the cutting work is completed, the original whole steel pipe is divided into two sections. Since one section of the steel pipe in the main placement plate 24 is positioned with the closed part 210 on the main placement plate 24 as the positioning reference during the positioning stage, the length of the remaining section of the steel pipe in the main placement plate 24 is accurately controlled. Therefore, it is a steel pipe that meets the requirements. The remaining section of the steel pipe in the secondary placement plate 26 is waste because it is the excess part cut from various steel pipes of different lengths. It can be recycled later;

[0121] After cutting is completed, the whole placement plate moves in the opposite direction of the cutting component 5 driven by the first threaded rod 28 until it moves to the lower rack 67. When the main placement plate 24 moves to the lower rack 67, the secondary placement plate 26 moves to the upper rack 68. Since the length of the first vertical plate 63 is greater than the length of the second vertical plate 610, the first gear disc 65 will not contact the upper rack 68. With the continuous movement of the whole placement plate, the first gear disc 65 meshes with the lower rack 67. The lower rack 67 is located below the first gear disc 65, driving the first gear disc 65 to rotate counterclockwise, while the second gear disc 69 meshes with the upper rack 68. The upper rack 68 is located above the second gear disc 69, driving the second gear disc 69 to rotate clockwise;

[0122] The overall effect presented is that the first gear disc 65 drives the first rotating rod 64 and the first blanking plate 61 to rotate counterclockwise, and the second gear disc 69 drives the second rotating rod 611 and the second blanking plate 62 to rotate clockwise. The finished steel pipe in the original main placement plate 24 is placed on the first blanking plate 61. Due to the counterclockwise rotation of the first blanking plate 61, it drives the finished steel pipe to fall from the left side of the bottom cavity of the main placement plate 24 and pass through the through groove 22 in the working platform 2 until it falls into the finished steel pipe storage box at the bottom;

[0123] The waste in the original secondary placement plate 26 is placed on the second blanking plate 62. Due to the clockwise rotation of the second blanking plate 62, it drives the waste to fall from the right side of the bottom cavity of the secondary placement plate 26 and pass through the through groove 22 in the working platform 2 until it falls into the waste storage box at the bottom. Through the settings of the rotating first blanking plate 61 and the second blanking plate 62, the automatic blanking and collection of the finished steel pipe and waste are respectively realized, improving the degree of automation;

[0124] It should be noted that when the first rotating rod 64 rotates, it will twist the fifth compression spring 66 sleeved on the first rotating rod 64. After blanking is completed and the whole placement plate moves towards the cutting component 5 again, when starting the next feeding and cutting process, the corresponding gears and racks drive the first blanking plate 61 to reset. The restored fifth compression spring 66 also returns to its original state. The restored fifth compression spring 66 can prevent the rotation of the first rotating rod 64, thereby preventing the rotation of the first blanking plate 61, playing a role in supporting the first blanking plate 61 and preventing the steel pipe from falling into the interior of the placement plate during feeding, resulting in the rotation of the first blanking plate 61;

[0125] Similarly, when the second rotating rod 611 rotates, it will twist the sixth contraction spring 612 sleeved on the second rotating rod 611. After the blanking is completed and the placement plate as a whole moves towards the cutting component 5 again, when starting the next feeding and cutting process, the corresponding gear and rack drive the second blanking plate 62 to reset. The sixth contraction spring 612 after reset also returns to its original state. The restored sixth contraction spring 612 can prevent the rotation of the second rotating rod 611, thereby avoiding the rotation of the second blanking plate 62, playing a role in supporting the second blanking plate 62, and preventing the steel pipe from falling into the interior of the placement plate during feeding, which may cause the second blanking plate 62 to rotate. The fifth contraction spring 66 and the sixth contraction spring 612 are sufficient to support the first blanking plate 61 and the second blanking plate 62. At the same time, before the steel pipe is cut into two sections, the steel pipe straddles the main placement plate 24 to connect the concave plate 25 and the secondary placement plate 26. The first blanking plate 61, the second blanking plate 62, and the remaining solid parts in the placement plate can share the weight of the entire steel pipe.

[0126] The present invention also provides a method for synchronously cutting multiple steel pipes, including the following steps:

[0127] S1. Place several steel pipes in each storage component 1 respectively, and start the linear movement component to drive the placement plate to move towards the cutting component 5 on the working platform 2;

[0128] S2. During the movement of the placement plate, it passes through the bottom of the storage component 1. When the placement plate passes through the bottom of the storage component 1, the feeding component 3 on one side pushes the steel pipes in the storage component 1 out one by one into the corresponding placement plate;

[0129] S3. The placement plates with steel pipes placed inside continue to move until the corresponding first positioning component extends into the placement plate and exerts extrusion on the axial direction of the steel pipes in the placement plate. Through the extrusion of the first positioning component, one end of each steel pipe in each placement plate abuts against the side of the corresponding placement plate away from the first positioning component;

[0130] S4. After one end of all the steel pipes is extruded and is in the same straight line, finally, the cutting disc 515 cuts all the steel pipes. After cutting, the original steel pipes with different lengths achieve unified lengths.

[0131] In the above specific embodiments, the technical problems solved by the present invention, the technical solutions, and the beneficial effects are further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
