Description

Technical Field

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

[0002] At present, in the steel pipe processing industry, synchronous cutting of multiple steel pipes is a common process, which aims to improve production efficiency and ensure that the length of the steel pipes after cutting is consistent to meet subsequent processing or use requirements. However, in the existing synchronous cutting devices for multiple steel pipes, there are still some technical difficulties, especially when dealing with steel pipes of different lengths to be cut.

[0003] After searching, it was found that the Chinese patent with the authorization announcement number CN211889212U discloses a pipe cutting device for stainless steel pipe production. The patent includes a frame, a fixing mechanism and a cutting mechanism. The device aligns and fixes the two ends of the steel pipe through the fixing mechanism, and the slide adjusts the position of the cutting mechanism to achieve precise cutting. The device can fix and cut multiple steel pipes at the same time, which improves the cutting efficiency; however, the patent has a low degree of automation and cannot achieve synchronous operation on multiple steel pipes. When multiple steel pipes of different lengths need to be cut synchronously, a key issue 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 they are cut directly, even if the cutting device itself has high precision, The length of the steel pipe after cutting may still not be uniform, which will seriously affect the quality of subsequent processing and the use effect. The traditional alignment and positioning method often relies on manual operation, that is, the worker aligns one end of the steel pipe through visual observation and manual adjustment. This method is not only inefficient, but also difficult to ensure the alignment accuracy. Especially when a large number of steel pipes need to be processed, the manual alignment method is not only time-consuming and labor-intensive, but also prone to human errors, resulting in poor alignment effects. In addition, the fixing mechanism of the patent is relatively simple in design and function, and lacks an effective alignment and positioning mechanism for steel pipes of different lengths. This requires workers to spend extra time and energy to make alignment adjustments in actual operations, thereby reducing overall production efficiency. Summary of the invention

[0014] The present invention also discloses a method for synchronously cutting multiple steel pipes, which uses the above-mentioned synchronous cutting device for multiple steel pipes and comprises the following steps: S1. Place a number of steel pipes in each of the storage components, start the linear moving component to drive the placement plate to move toward the cutting component on the working platform; 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; 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; 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.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects: 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.

[0016] 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.

[0017] 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.

[0018] Through the setting of the three structures of the placement plate and the positioning plate, the placement plate is divided into a main placement plate, a connecting concave plate and an auxiliary placement plate. The cutting disc moves from the connecting concave plate to divide the steel pipe into two sections. The main placement plate contains the required steel pipe, and the auxiliary placement plate contains the redundant part of the steel pipe. To further ensure the stability of the cutting, when the placement plate moves toward the cutting part, it will drive the two positioning plates at the main placement plate and the auxiliary placement plate to move, thereby squeezing and fixing the steel pipes in the main placement plate and the auxiliary placement plate in the longitudinal position, that is, fixing the two sides of the steel pipe at the cutting point, so as to achieve a more stable cutting effect.

[0019] By setting up structures such as the cutting disc and the deflection plate, the cutting disc can be driven by the threaded rod three to achieve linear movement in a horizontal position. However, if there are too many steel pipes to be cut, the cutting quality will be reduced if the cutting disc works for a long time. Therefore, an additional deflection plate is provided. The deflection plate adds an arc-shaped movement path to the cutting disc on the basis of the overall linear movement. The arc-shaped cutting path can make the cutting force more evenly distributed, thereby reducing local stress concentration and reducing the risk of material deformation or cracking.

[0020] Through the arrangement of structures such as the unloading assembly and the placing plate, when the placing plate drives the two sections of steel pipes after cutting to move toward the unloading assembly, they come into contact with the upper rack and the lower rack in the unloading assembly, thereby causing unloading plate 1 and unloading plate 2 in the main placing plate and the auxiliary placing plate to rotate. Unloading plate 1 and unloading plate 2 originally used to support the steel pipes drive the steel pipes thereon to fall from the bottom of the placing plate into the container used to respectively accommodate the two sections of steel pipes.

The extension plate 422 is suitable for sliding on the outer peripheral surface of the guide rod 2 423 when following the movement of the movable sleeve 415. The outer fixed sleeve of the movable sleeve 415 located at the main placement plate 24 is provided with a gear 1 416, and the outer fixed sleeve of the rotating sleeve 418 located at the main placement plate 24 is provided with a gear 2 419. The main placement plate 24 is connected to the corresponding sides of the gear 1 416 and the gear 2 419 with a rack 1 417 and a rack 2 420. The rack 1 417 is meshed with the gear 1 416, and the rack 2 420 is meshed with the gear 2 419.

The auxiliary placement plate 26 and the corresponding sides of the gear three 424 and the gear four 425 are connected with a rack three 426 and a rack four 427. The rack three 426 is meshed with the gear three 424, and the rack four 427 is meshed with the gear four 425.

[0030] The working principle of this embodiment is as follows: When in use, several steel pipes are placed in each storage box 11 respectively, and the linear moving component is started to drive the placement plate to move on the working platform 2, thereby driving the loading component 3 to take out a steel pipe from the corresponding storage box 11 and send it to the placement plate. After all the placement plates are placed with a steel pipe, they continue to move on the working platform 2. During the movement, the corresponding positioning components squeeze the axial direction of the steel pipes in the corresponding placement plates, so that one end of all the steel pipes is against the closed part 210 of the placement plate, showing that the same end of all the steel pipes is in a straight line. At this time, cutting by the cutting disc 515 can make all the steel pipes be cut into uniform lengths; Specifically, the linear motor 21 is started to drive the threaded rod 28 to rotate, thereby driving the moving plate 27 to move linearly, and then driving the placement plate to move on the slide rail 23 of the working platform 2. The threaded rod 28 and the moving plate 27 can be assembled through a ball nut. The threaded rod realizes linear transmission, which is a prior art and will not be described in detail here. A push plate 32 is provided on the working platform 2. The push plate 32 will pass through the bottom of the storage box 11 when following the movement of the placement plate. In this process, the push plate 32 enters through the push port 12 of the storage box 11, and applies a thrust to a steel pipe located at the bottom layer of the storage box 11. During the 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 loading. It should be noted that the push port 12 can only allow the push plate 32 to pass through, while the steel pipe at the discharge port 13 can also pass through. A limiting portion 14 is provided at the bottom of the storage box 11, and the storage The steel pipe in the box 11 cannot fall from the bottom of the storage box 11 and can only be pushed out from the discharge port 13 by the push plate 32. When it is necessary to load materials again, the placement plate needs to be reset, that is, the placement plate moves in the opposite direction on the working platform 2. At this time, the push plate 32 enters the storage box 11 from the discharge port 13. Because the new steel pipe located at the bottom layer contacts, but the push port 12 cannot allow the steel pipe to pass, the push plate 32 cannot push the steel pipe at this time. At this time, the steel pipe exerts pressure on the inclined part at the top of the push plate 32. The stressed push plate 32 squeezes the telescopic rod 13 and the contraction spring 134 downward, and slides into the fixed plate 31, so as to realize that the push plate 32 passes through the storage box 11 normally to the other side of the storage box 11. After the steel pipe loses the squeezing of the push plate 32, the push plate 32 is reset by the telescopic rod 133 and the contraction spring 134. The reset push plate 32 performs automatic loading again according to the above method; After the push plate 32 pushes the single steel pipe into the placement plate, the placement plate continues to move toward the cutting component 5 on the work platform 2 under the drive of the threaded rod 1 28. During the movement, it will simultaneously drive the positioning components 2, 3 and 1 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 auxiliary placement plate 26. The position of the connecting concave plate 25 is lower than the main placement plate 24 and the auxiliary placement plate 26, so that a gap appears between the main placement plate 24 and the auxiliary placement plate 26. The cutting disc 515 cuts the steel pipe in the gap and divides the steel pipe into two sections, one in the main placement plate 24 and the other in the auxiliary placement plate 26. The movement of the placement plate drives the positioning component 2 in such a way that two symmetrically arranged matching plates 47 are provided in the placement plate, and two extrusion plates 45 corresponding to the matching plates 47 are provided on the working platform 2. When the placement plate continues to move toward the cutting component 5 after the steel pipe is placed, the inclined surface 1 46 on the fixedly arranged extrusion plate 45 will squeeze the inclined surface 2 48 on the matching plate 47, thereby pushing the matching plate 47 toward the inside of the placement plate. An intermediate plate 410 is provided on the matching plate 47, and a contraction spring 3 49 is provided between the intermediate plate 410 and the inner wall of the placement plate. The contraction spring 3 49 is used to stabilize the movement and resetting of the matching plate 47. When both matching plates 47 are squeezed toward the inside of the placement plate, the steel pipe in the placement plate can be pushed. In order to cope with various steel pipes with different diameters, a contraction spring 411 is provided on the middle plate 410, and a positioning plate 412 is provided on the contraction spring 411. The positioning plate 412 contacts the outer peripheral surface of the steel pipe. The movement of the matching plate 47 after being squeezed by the squeezing plate 45 is limited. Therefore, a contraction spring 411 and a positioning plate 412 are provided to prevent the middle plate 410 from being unable to act on the steel pipe with a smaller diameter. This setting improves the adaptive ability and can automatically adjust according to the steel pipes with different diameters, ensuring that the steel pipe in the placement plate can be centered, reducing shaking, and providing a certain clamping force to prepare for subsequent cutting work. At the same time, as the placement plate moves, the positioning plate 44 extends into the opening portion located at the auxiliary placement plate 26, and the axial direction of the steel pipe in the placement plate is squeezed through the opening portion, so that the end of the steel pipe away from the positioning plate 44 is pressed against the closed portion 210 of the placement plate. The components on each working platform 2 are the same, so the same end of the steel pipes in all the placement plates will be pressed against their respective corresponding closed portions 210. At this time, the same ends of these steel pipes are in the same straight line. The subsequent cutting disk 515 can ensure that no matter whether the initial lengths of these steel pipes are equal, the remaining lengths after being cut are equal. The length of the steel pipes in the main placement plate 24 is uniform, which can meet the needs of production. The positioning plate 1 44 is connected by the telescopic rod 2 41 and the contraction spring 2 43 to achieve stable movement and reset of the positioning plate 1 44. The positioning plate 1 44 can be retracted to squeeze steel pipes of different lengths. When all the placement plates move synchronously and the moving distance is the same, the steel pipe with a longer length is squeezed by the positioning plate 1 44 with a greater pressure, and the steel pipe with a shorter length is squeezed by the positioning plate 1 44 with a smaller pressure. Regardless of the size of the squeezing force, it can be ensured that the steel pipe is stably pressed against the corresponding closed part 210. 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; The positioning plate three 421 located at the auxiliary 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 auxiliary placement plate 26 is used to position and limit the steel pipe at the auxiliary placement plate 26. The only difference is that the width of the rack three 426 and the rack four 427 is smaller than 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. 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 To drive gear three 424 and gear four 425 to rotate, thereby driving the positioning plate three 421 at the auxiliary placement plate 26 to work normally. It should be noted that rack one 417, rack two 420, rack three 426 and rack four 427 can 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 state above the placement plate, and the rack that controls the movement of the movable sleeve 415 can be replaced according to the different diameters of the steel pipes to be cut. The longer the rack is, the more turns the gear used to control the movement of the movable sleeve 415 drives, and the greater the distance the movable sleeve 415 descends, thereby realizing positioning restrictions on steel pipes of different sizes. The positioning plate 1 44, the positioning plate 2 412 and the positioning plate 3 421 all work synchronously when the placement plate continues to move toward the cutting component 5 after placing the steel pipe, and simultaneously complete multiple positioning and restrictions on the outer peripheral surface in the axial direction, horizontal direction and longitudinal direction of the steel pipe, thereby improving the stability during subsequent cutting; It should be noted that a waste chip groove is provided in each connecting groove, and 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.

[0031] Embodiment 2: as Fig.14 As shown, this embodiment further includes the following structure on the basis of the first embodiment: the cutting device also includes a support frame 51, the driving assembly is arranged on the support frame 51, and the driving assembly includes a driving motor 52 installed on the support frame 51, a threaded rod 3 54 rotatably installed in the support frame 51, a guide rod 3 53 fixedly connected in the support frame 51, a transmission sleeve 1 55 assembled on the outside of the threaded rod 3 54, and a driving box 514; The driving motor 52 is connected to the threaded rod three 54 so as to drive the threaded rod three 54 to rotate in the support frame 51, thereby driving the transmission sleeve 1 55 to move along the axial direction of the threaded rod three 54. The transmission sleeve 1 55 is connected to the driving box 514, and the driving box 514 is connected to the cutting disk 515 so as to drive the cutting disk 515 to rotate. The cutting disk 515 is located in the cutting chamber.

[0032] like Fig.15 As shown, the driving assembly further includes a direction-changing mechanism, which is suitable for connecting the transmission sleeve 55 and the driving box 514, and the direction-changing mechanism includes a direction-changing plate 512, which is connected to the bottom of the transmission sleeve 55; The bottom of the transmission sleeve 1 55 is connected to a housing 56, and a control motor 57 is installed on the housing 56. A threaded rod 4 58 is rotatably installed in the housing 56, and a transmission sleeve 2 59 is assembled on the outside of the threaded rod 4 58. The control motor 57 is connected to the threaded rod 4 58 to drive the threaded rod 4 58 to rotate in the housing 56, and then drive the transmission sleeve 2 59 to move along the axis direction of the threaded rod 4 58; A rotating shaft 510 is fixedly connected inside the transmission sleeve 59, and a connecting shaft 513 is fixedly connected to one side of the driving box 514. A changing groove that runs through the changing plate 512 is opened, and the changing groove is arc-shaped. The connecting shaft 513 passes through the changing groove and is slidably set in the changing groove. A hinged rod 511 is set between the connecting shaft 513 and the rotating shaft 510. One end of the hinged rod 511 is movably sleeved on the outer peripheral surface of the connecting shaft 513, and the other end of the hinged rod 511 is movably sleeved on the outer peripheral surface of the rotating shaft 510. The transmission sleeve 59 is suitable for driving the connecting shaft 513 and the driving box 514 to move along the direction of the changing groove when being driven to move in a straight line, thereby driving the cutting disk 515 to move along the direction of the changing groove.

[0033] The working principle of this embodiment is as follows: After the steel pipe in the placement plate is multi-positioned and restricted by the positioning component 4, the drive box 514 is started to drive the cutting disk 515 to rotate. The drive box 514 includes a motor and a gear box. This part belongs to the prior art and will not be described in detail here. After the cutting disk 515 rotates normally, the drive motor 52 is started to drive the threaded rod three 54 to rotate. The threaded rod three 54 rotates and drives the transmission sleeve one 55 to move linearly. At the same time, the transmission sleeve one 55 slides on the outside of the guide rod three 53 to prevent the transmission sleeve one 55 from rotating under the drive of the threaded rod three 54. When the transmission sleeve one 55 moves linearly, it can drive the drive box 514 to move linearly, and then drive the cutting disk 515 to move linearly. The cutting disk 515 moves in the cutting chamber formed between the main placement plate 24, the auxiliary placement plate 26 and the connecting groove, and all the positioned steel pipes are cut synchronously, thereby improving the efficiency of the cutting work. Since it is necessary to cut several steel pipes at the same time, the wear on the tool is large, and the cutting quality of each steel pipe cannot be guaranteed to be the same. Therefore, a deflection plate 512 is arranged between the drive box 514 and the transmission sleeve 1 55 to change the cutting path of the cutting disc 515. When in use, the transmission sleeve 1 55 is used to drive all the parts thereunder to move to the steel pipe that needs to be cut, and then the control motor 57 is started to drive the threaded rod 4 58 to rotate. When the threaded rod 4 58 rotates, it drives the transmission sleeve 2 59 to move in a straight line. The transmission sleeve 2 59 is partially located in the groove of the shell 56 where the threaded rod 4 58 is installed, which limits the transmission sleeve 2 59 to prevent self-rotation. A connecting shaft 513 is connected to the drive box 514, and the connecting shaft 513 passes through the deflection groove of the deflection plate 512. A rotating shaft 510 is arranged in the transmission sleeve 2 59. A hinged rod 511 is movably hinged between the rotating shaft 510 and the connecting shaft 513. When 59 is driven to move, it synchronously drives the articulated rod 511 to move, and the articulated rod 511 drives the connecting shaft 513 to move along the trajectory of the redirecting groove. The redirecting groove is an arc-shaped setting, so as to drive the driving box 514 and the cutting disk 515 to move in an arc-shaped direction, and cut the steel pipe to be cut by an arc-shaped knife-moving method. When the transmission sleeve 2 59 drives the connecting shaft 513 to walk the entire redirecting groove, the cutting is completed. After completion, the transmission sleeve 2 59 moves and resets under the reverse rotation of the threaded rod 4 58, thereby driving the connecting shaft 513 to reset, and then driving the cutting disk 515 to reset, so that all the cutting work of the single steel pipe is completed, and then the transmission sleeve 1 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 transmission sleeve 2 59 to move, thereby driving the cutting disk 515 to cut the steel pipe, and the cycle can realize the cutting work of all steel pipes; The setting of the deflection plate 512 is mainly to realize the change of the cutting disc 515 from a straight cutting form to an arc-shaped cutting form. The arc-shaped path can ensure that each steel pipe is subjected to uniform cutting force during cutting, which helps to improve the cutting quality and reduce deformation and damage during the cutting process. At the same time, it can effectively disperse the stress generated during the cutting process and reduce local stress concentration, thereby reducing the risk of damage to the steel pipe during the cutting process. The arc-shaped cutting path can also better adapt to the circular contour of the steel pipe and reduce the error and unevenness caused by straight-line cutting.

[0034] Embodiment three: as Figure 12-13As shown, this embodiment further includes the following structure on the basis of the first embodiment: the cutting device also includes a blanking assembly 6, the blanking assembly 6 includes a blanking plate 1 61 arranged in the main placement plate 24, a blanking plate 2 62 arranged in the auxiliary placement plate 26, a rotating mechanism 1 corresponding to the blanking plate 1 61, and a rotating mechanism 2 corresponding to the blanking plate 2 62, the rotating mechanism 1 is suitable for being connected with the blanking plate 1 61 to drive the blanking plate 1 61 to rotate in the main placement plate 24 toward the bottom of the main placement plate 24, and the rotating mechanism 2 is suitable for being connected with the blanking plate 2 62 to drive the blanking plate 2 62 to rotate in the auxiliary placement plate 26 toward the top of the auxiliary placement plate 26; The rotating mechanism 1 includes two vertical plates 163, a rotating rod 164 and a gear plate 165. The tops of the two vertical plates 163 are connected to the bottom of the main placement plate 24. The rotating rod 164 is rotatably installed inside the two vertical plates 163. The rotating rod 164 partially extends to the outside of the vertical plates 163. The gear plate 165 and the blanking plate 161 are both fixedly sleeved on the outer circumference of the rotating rod 164 located between the two vertical plates 163. A contraction spring 566 is sleeved on the extended part of the rotating rod 164. One end of the contraction spring 566 is connected to the rotating rod 164, and the other end of the contraction spring 566 is connected to the vertical plate 163. A lower rack 67 is connected in the through groove 22 of the working platform 2. The lower rack 67 is meshed with the gear plate 165. The gear plate 165 is suitable for following the main placement plate 24 to move toward the lower rack 67 and is driven to rotate by the lower rack 67. The second rotating mechanism includes two vertical plates 610, a rotating rod 611 and a gear plate 69. The tops of the two vertical plates 610 are connected to the bottom of the auxiliary placement plate 26. The rotating rod 611 is rotatably installed inside the two vertical plates 610. Part of the rotating rod 611 extends to the outside of the vertical plates 610. The gear plate 69 and the second feeding plate are fixedly sleeved on the outer circumferential surface of the rotating rod 611 located between the two vertical plates 610. A contraction spring 612 is sleeved on the protruding part of the rotating rod 611. The two ends of the contraction spring 612 are connected to the rotating rod 611, and the other two ends of the contraction spring 612 are connected to the vertical plates 610. An upper rack 68 is connected to the through groove 22 of the working platform 2, and the upper rack 68 is meshed with the gear plate 69. The gear plate 69 is suitable for following the auxiliary placement plate 26 to move in the direction of the upper rack 68 and be driven to rotate by the upper rack 68.

[0035] The working principle of this embodiment is as follows: After the cutting work is completed, the original whole steel pipe is divided into two sections. Since the section of the steel pipe in the main placement plate 24 is based on 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, so it is a steel pipe that meets the requirements, and the remaining section of the steel pipe in the auxiliary placement plate 26 is the excess part cut from various steel pipes of different lengths, so it is waste and can be recycled later; After the cutting is completed, the placing plate as a whole moves in the opposite direction of the cutting component 5 under the drive of the threaded rod 1 28 until it moves to the lower rack 67. When the main placing plate 24 moves to the lower rack 67, the auxiliary placing plate 26 moves to the upper rack 68. Since the length of the vertical plate 1 63 is greater than the length of the vertical plate 2 610, the gear plate 1 65 will not contact the upper rack 68. When the placing plate as a whole continues to move, the lower gear plate 1 65 and the lower rack 67 are meshed. The lower rack 67 is located below the gear plate 1 65, driving the gear plate 1 65 to rotate counterclockwise, and the gear plate 2 69 is meshed with the upper rack 68. The upper rack 68 is located above the gear plate 2 69, driving the gear plate 2 69 to rotate clockwise. The overall effect is that the gear plate 1 65 drives the rotating rod 1 64 and the blanking plate 1 61 to rotate counterclockwise, and the gear plate 2 69 drives the rotating rod 2 611 and the blanking plate 2 62 to rotate clockwise. The finished steel pipes in the main placement plate 24 are originally placed on the blanking plate 1 61. Due to the counterclockwise rotation of the blanking plate 1 61, the finished steel pipes are driven to fall from the left side of the bottom cavity of the main placement plate 24 and pass through the through slot 22 in the working platform 2 until they fall into the finished steel pipe storage box at the bottom; The waste in the auxiliary placement plate 26 is originally placed on the unloading plate 2 62. Due to the clockwise rotation of the unloading plate 2 62, the waste is driven to fall from the right side of the bottom cavity of the auxiliary placement plate 26 and pass through the through slot 22 in the working platform 2 until it falls into the waste storage box at the bottom. The automatic unloading and collection of the finished steel pipe and the waste are respectively realized by the setting of the rotating unloading plate 1 61 and the unloading plate 2 62, thereby improving the degree of automation. It should be noted that when the rotating rod 64 rotates, the contraction spring 66 sleeved on the rotating rod 64 will be twisted. After the unloading is completed, the placing plate as a whole moves toward the cutting component 5 again. When the next loading and cutting process begins, the corresponding gear and rack drive the unloading plate 61 to reset. The resetting contraction spring 66 also returns to its original state. The restored contraction spring 66 can prevent the rotating rod 64 from rotating, and then prevent the unloading plate 61 from rotating, playing a role in supporting the unloading plate 61, and preventing the steel pipe from falling into the inside of the placing plate during loading, causing the unloading plate 61 to rotate. The spring 612 is pressed against the top of the plate 61 and the spring 613 is pressed against the bottom of the plate 61. The spring 612 is pressed against the top of the plate 61 and the spring 613 is pressed against the bottom of the plate 61.

[0036] The present invention also provides a method for synchronously cutting multiple steel pipes, comprising the following steps: S1. Place several steel pipes in each storage assembly 1, start the linear moving assembly to drive the placement plate to move toward the cutting component 5 on the working platform 2; S2, the placement plate passes through the bottom of the storage assembly 1 during the movement, and when the placement plate passes through the bottom of the storage assembly 1, the loading assembly 3 on one side pushes the steel pipe in the storage assembly 1 into the corresponding placement plate; S3, a plurality of placement plates with steel pipes placed inside continue to move until the corresponding positioning assembly 1 extends into the placement plate and squeezes the axial direction of the steel pipe in the placement plate, and through the squeezing of the positioning assembly 1, one end of the steel pipe in each placement plate is pressed against the side of the corresponding placement plate away from the positioning assembly 1; S4. After one end of all the steel pipes are squeezed, they are aligned in a straight line. Finally, the cutting disc 515 cuts all the steel pipes. After cutting, the steel pipes of different lengths are unified in length.
