Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting, and in particular to a pipe cutting device for electric power construction and a cutting method thereof. Background Art

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipe fittings. There are many types of pipes and the materials are also different. Power pipes are often used in power construction. However, according to different usage requirements, power pipes need to be cut before use.

[0003] After searching, the Chinese patent document with the announcement number CN115780885B discloses a pipe cutting device and method for power construction, including a workbench, a fixing device is provided in the middle of the upper surface of the workbench, an adjustment plate and a fixing rod are set, the fixing rod is pulled upward in turn, and the adjustment plate is rotated clockwise. When the adjustment plate rotates, the extrusion block contacts the pipe fitting, so as to facilitate the fixing operation before cutting pipe fittings of different diameters. A roller and a fan are set. When the roller cuts the pipe fitting circumferentially with the cutting knife, the active bevel gear and the driven bevel gear are engaged to drive the fan to rotate. When the fan rotates, the pipe fitting is cooled when it is cut, and at the same time, the flying chips, dust, etc. generated when the pipe fitting is cut are blown into the collection bucket for collection. By setting a support ring, the notch in the middle of the outer side of the support ring corresponds to the cutting knife, so that the cutting knife can be more stable and smooth when cutting the pipe fitting circumferentially, and deformation of the pipe fitting when cutting is avoided.

[0004] However, the above invention has the following shortcomings: the above device completes production by feeding the pipe first and then cutting, that is, feeding the pipe at one end, then clamping it, and finally cutting it, which is three steps.

[0039] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention provides a pipe cutting device and a cutting method for electric power construction through improvement. The technical solution of the present invention is:

[0041] Embodiment 1

[0042] like Figures 1 to 10As shown, an embodiment of the present invention provides a pipe cutting device for power construction, including a workbench 1, the workbench 1 is made of metal, and also includes:

[0043] A feeding assembly for feeding round tubes, the feeding assembly being installed on the table of the workbench 1;

[0044] The cutting assembly 5 includes a first fixed frame 23, which is arranged adjacent to the feeding assembly. The bottom of the first fixed frame 23 is fixed on the table of the workbench 1. A cutting mechanism for cutting the pipe is arranged inside the first fixed frame 23. A moving mechanism for making the cutting mechanism move back and forth in a straight line is arranged inside the first fixed frame 23.

[0045] From the above description, the technical solution of the present invention is known: the feeding component feeds the pipe into the first fixed frame 23, the cutting mechanism moves in the same direction as the pipe through the moving mechanism, and the moving speed of the cutting mechanism is the same as the linear moving speed of the pipe. After the cutting mechanism cuts the pipe, it is reset and reciprocates in this way, making the cutting process smoother, eliminating the step of repeated clamping, and improving production efficiency.

[0046] Specifically, a material discharge port is provided on the table top of the workbench 1, and the material discharge port is located in the first fixed frame 23, and the pipes after cutting fall through the material discharge port. It can be seen that a collection box is provided below the material discharge port for centrally collecting the cut pipes.

[0047] Combined with Figure 1 As shown, the feeding assembly described above includes a plurality of feeding mechanisms 4, and the plurality of feeding mechanisms 4 are all arranged on the workbench 1, and the plurality of feeding mechanisms 4 are linearly distributed at equal distances.

[0048] More specifically, in conjunction with Figure 2 and Figure 3As shown, the feeding mechanism 4 includes a support seat 8, the bottom of the support seat 8 is fixedly mounted on the workbench 1, a cylindrical second fixing frame 9 is fixed on the top of the support seat 8, the pipe is inserted into each second fixing frame 9, and a plurality of rotating holes with the central axis as the center and equidistantly distributed in an annular shape are opened on the outer side of the second fixing frame 9, an internal threaded cylinder 13 is rotatably mounted inside the rotating hole, an external threaded column 12 is threadedly mounted inside the internal threaded cylinder 13, and a first concave block 20 is fixed at one end of the external threaded column 12 located in the second fixing frame 9 A roller 21 is rotatably mounted in the recess of the first concave block 20, and the central axis of the roller 21 intersects with the central axis of the second fixing frame 9 in a non-planar manner. A third fixing frame 10 is fixed on the outside of the second fixing frame 9 with its central axis as the center and distributed in an equidistant ring. A square rod 11 is fixed inside the third fixing frame 10, and a square hole coaxially arranged with the external thread column 12 is opened at one end thereof, and one end of a plurality of square rods 11 is inserted into each square hole. A first rotating mechanism that enables each internal thread cylinder 13 to rotate synchronously is arranged on the outside of the second fixing frame 9;

[0049] To supplement the roller 21, the circumferential surface of the roller 21 may be elliptical, and the surface contact between the roller 21 and the pipe may be replaced with point contact, so that the roller 21 can better move the pipe.

[0050] From the above-described relationships, it can be known that: the pipes are inserted into the second fixing frames 9, the internal threaded tubes 13 are rotated by the first rotating mechanism, and the internal threaded tubes 13 cause the external threaded rods 28 to move linearly along the square rods 11 through threaded transmission, that is, the external threaded rods 28 synchronously move linearly toward the center of the second fixing frames 9 until the external threaded rods 28 contact the pipes.

[0051] More specifically, in conjunction with Figure 2 and Figure 3 As shown, the first rotating mechanism includes a bevel gear ring 22 and a plurality of transmission bevel gears 14, the plurality of transmission bevel gears are coaxially fixed with the plurality of internal threaded cylinders 13, the bevel gear ring 22 is coaxially arranged with the second fixing frame 9 and the two form a rotational fit, each transmission bevel gear 14 is evenly meshed with the bevel gear ring 22, and each bevel gear ring 22 is jointly provided with a second rotating mechanism;

[0052] It can be known from the above-described relationships that when the bevel gear ring 22 rotates, the bevel gear ring 22 rotates through the transmission bevel gears 14 meshing therewith, and the internal threaded cylinder 13 coaxially fixed with the transmission bevel gear 14 rotates.

[0053] More specifically, in conjunction with Figure 2 and Figure 3As shown, the second rotating mechanism includes a plurality of gear sets, the gear set includes a driven gear ring 15 and a transmission gear 16, the driven gear ring 15 is coaxially fixed with the bevel gear ring 22, two support plates 19 are fixed on the table top of the workbench 1, a transmission rod 17 is installed on the opposite side of the two support plates 19 for common rotation, a second servo motor 18 is fixedly installed on the outer side of one of the support plates 19, the output shaft of the second servo motor 18 is coaxially fixed with the transmission rod 17, the transmission gear 16 is coaxially fixed with the transmission rod 17, and the transmission gear 16 is meshed with the driven gear ring 15;

[0054] Supplementary explanation of the second servo motor 18: The second servo motor 18 uses a worm reduction servo motor, so that the second servo motor 18 can output a larger torque, and the second servo motor 18 has a self-locking property;

[0055] From the above description of various relationships, it can be known that the second servo motor 18 causes the transmission rod 17 to rotate axially through the output shaft, and the various transmission gears 16 on the transmission rotate synchronously. The transmission gear 16 drives the driven gear ring 15 meshing with it, and the driven gear ring 15 drives the bevel gear ring 22 fixed thereto to rotate.

[0056] Specifically, in combination with Figure 1 As shown, a slide rail 2 is fixed to the tabletop of the workbench 1, and a slide table is provided on the outer side of each slide rail 2, and a first servo motor 3 is fixed on the top of the slide table. A second cardan shaft 7 is fixed to two rollers 21 that are opposite to each other in every two adjacent second fixed frames 9, and each second cardan shaft 7 is located at the same position. The rollers 21 located at the same end position and equipped with the second cardan shaft 7 and the output shaft of the first servo motor 3 are jointly equipped with a first cardan shaft 6. When the rollers 21 located at the same end position and equipped with the second cardan shaft 7 are telescopically moved, the first servo motor 3 is pulled, and the first servo motor 3 slides along each slide rail 2;

[0057] Through the above-described relationships, it can be known that the first servo motor 3 rotates the first cardan shaft 6 through the output shaft, and the first cardan shaft 6 rotates the roller 21 located at the same end position and installed with the second cardan shaft 7. Since two of the rollers 21 facing each other in every two adjacent second fixed frames 9 are commonly fixed with a second cardan shaft 7, each second cardan shaft 7 is located at the same position, so that one of the rollers 21 in each second fixed frame 9 rotates synchronously, and the roller 21 moves the pipe through friction. Since the central axis of the roller 21 intersects with the central axis of the second fixed frame 9 in a non-planar manner, the pipe rotates and moves forward.

[0058] Specifically, in combination with Figure 6-Figure 10As shown, the moving mechanism includes an externally threaded rod 28, the two ends of the externally threaded rod 28 are respectively fixed to the two ends in the first fixed frame 23, and the two ends of the second fixed frame 9 are commonly fixed with a guide rod 24, and the outer sides of the guide rod 24 and the externally threaded rod 28 are commonly provided with a second recessed block 27, and the two ends of the second recessed block 27 are respectively provided with a first through hole and a second through hole, and the outer side of the externally threaded rod 28 is provided with a plurality of first guide grooves, and the first guide groove is slidably provided with a first guide bar 38, and the first guide bar 38 is fixed in the first through hole, and the outer side of the guide rod 24 is provided with a plurality of second guide grooves, and the second guide groove is slidably provided with a second guide bar 39, and the second guide bar 39 is fixed in the second through hole, and the outer side of the externally threaded rod 28 is threadedly installed with an inner screw barrel 26, and one end of the inner screw barrel 26 is rotatably installed on the second recessed block 27, and the outer side of the second recessed block 27 is fixedly installed with a first extension plate 49, and the outer side of the first extension plate 49 is fixed with a first contact column 50, and the first fixed frame 23 A second contact column 51 is fixed to one end of the interior of the guide rod 24, a moving block 29 is slidably sleeved on the outer side of the guide rod 24, a third guide strip is slidably arranged in the second guide groove, the third guide strip is fixed to the moving block 29, a fixed plate 30 is fixed to the top of the moving block 29, a third through hole is provided on the outer side of the top of the fixed plate 30, a rotating rod 35 is rotatably installed inside the third through hole, a third concave block 36 is fixed to one end of the rotating rod 35, a round wheel 37 is rotatably installed in the notch of the third concave block 36, a second fixed block 34 is fixed to the outer side of the fixed plate 30, a toggle plate 33 is fixed to the other end of the rotating rod 35, a first fixed block 31 is fixed to the outer side of one end of the toggle plate 33, a tension spring 32 is fixed to the first fixed block 31 and the second fixed block 34 together, a power rod 25 is rotatably installed at both ends of the first fixed frame 23, the power rod 25 is in contact with the round wheel 37, a third servo motor 46 is fixed to the outer side of the first fixed frame 23, and the output shaft of the third servo motor 46 is coaxially fixed to the power rod 25;

[0059] Through the above connection relationships, it can be seen that: Figure 7 The third servo motor 46 causes the power rod 25 to rotate axially through the output shaft, and the tension spring 32 pulls the toggle plate 33, so that the central axis of the circular wheel 37 intersects with the central axis of the power rod 25 in different planes. The power rod 25 causes the circular wheel 37 to move linearly along the power rod 25 through friction. When the toggle plate 33 contacts the first contact column 50 on the second recessed block 27, the first contact column 50 pushes the toggle plate 33, and the toggle plate 33 is pushed to another place. The toggle plate 33 toggles the circular wheel 37 to the other side through the rotating rod 35, so that the circular wheel 37 moves in the opposite direction until the toggle plate 33 contacts the second contact column 51 on the other side, so that it can be reset and move linearly; the inner screw barrel 26 is rotated, and the inner screw barrel 26 causes the second recessed block 27 to move on the external threaded rod 28 through bolt transmission, thereby adjusting the reciprocating spacing of the circular wheel 37, that is, adjusting the cutting length of the circular saw machine 45.

[0060] Specifically, in combination with Figure 6-Figure 10 As shown, a plurality of guide columns 43 are fixed to the bottom of the moving block 29, a limit block 41 is fixed to the bottom end of the guide column 43, a moving plate 40 is provided on the sliding sleeve of the plurality of guide columns 43, a return spring 42 is provided on the outer side of the guide column 43, and the two ends of the return spring 42 are respectively in contact with the limit block 41 and the moving plate 40, a mounting plate 44 is fixed to the bottom of the moving plate 40, a circular saw 45 is fixed to the bottom end of the mounting plate 44, a second extension plate 52 is fixed to the outer side of the second concave block 27, a guide structure 48 is provided on the outer side of the second extension plate 52, and the guide structure 48 includes a guide plate 54, one end of which is fixed to the first On the second extension plate 52, the other end of the guide plate 54 is tilted upward, and a groove 58 is provided on the outer side of the tilted end of the guide plate 54, and fourth through holes are provided at both ends of the notch of the groove 58. A rotating shaft 56 is rotatably installed inside the two fourth through holes, and a rotating plate 57 is fixed on the outer side of the rotating shaft 56. A limiting plate 59 is fixed on one end of the rotating plate 57. A circular hole groove 53 coaxially arranged with the rotating shaft 56 is provided on the outer side of the guide plate 54, and a coil spring 55 is fixed on the inner side wall of the circular hole groove 53 and the outer side of the rotating shaft 56. A vertical plate 60 is fixed on the top of the movable plate 40, and a contact wheel 47 is rotatably installed on one end of the vertical plate 60.

[0061] Through the above connection relationships, it can be seen that when the circular saw 45 and the pipe are moving in the same direction and at the same speed, when the contact wheel 47 on the moving plate 40 contacts the rotating plate 57 on the tilted end of the guide plate 54, the rotating plate 57 cannot rotate due to the restriction of the limit plate 59 (such as Fig.10 As shown), the contact wheel 47 moves downward, and the contact wheel 47 pushes the movable plate 40 downward through the vertical plate 60. The movable plate 40 compresses the reset spring 42, and the circular saw of the circular saw machine 45 contacts the pipe. Since the circular saw machine 45 and the pipe have the same linear movement speed, and since the pipe rotates and moves forward at the same time, the pipe rotates relative to the circular saw machine 45, and the circular saw machine 45 performs circular cutting on the pipe. After the cutting is completed, the contact wheel 47 reaches one end of the guide plate 54, and the reset spring 42 resets, and the circular saw machine 45 moves up and separates from the pipe. When the circular saw machine 45 is resetting, it contacts the rotating plate 57, and the rotating plate 57 is pushed, which does not hinder the resetting of the circular saw machine 45.

[0062] Embodiment 2

[0063] This embodiment discloses a method for cutting pipes for electric power construction, and the specific steps are as follows:

[0064] The first step: insert the pipe into the second fixing frame 9 of each feeding mechanism 4, start the feeding assembly, use a tachometer to detect the linear moving speed of the pipe, and then remove the pipe;

[0065] The second step is to move the cutting mechanism in the first fixed frame 23 through the moving mechanism, use a speed meter to detect the linear moving speed of the cutting mechanism, and continuously adjust the cutting mechanism so that the moving speed is the same as the linear moving speed of the pipe;

[0066] The third step: insert the feeding mechanism 4 into the second fixed frame 9, so that the feeding assembly and the cutting mechanism work synchronously. At this time, the circular saw of the circular saw machine 45 in the cutting mechanism is synchronized with the moving speed of the pipe. The circular saw machine 45 cuts the pipe. After the cutting is completed, the cutting mechanism is reset, and then the feeding mechanism 4 continues to feed the pipe. Then the cutting mechanism is synchronized with the moving speed of the pipe again, and it goes back and forth.

[0067] In summary, the working principle of cutting is as follows: insert the pipe into each second fixed frame 9, the second servo motor 18 causes the transmission rod 17 to rotate axially through the output shaft, and each transmission gear 16 on the transmission rotates synchronously, and the transmission gear 16 drives the driven gear ring 15 meshing with it, and the driven gear ring 15 drives the bevel gear ring 22 fixed with it to rotate. When the bevel gear ring 22 rotates, the bevel gear ring 22 rotates through each transmission bevel gear 14 meshing with it, and the internal threaded cylinder 13 coaxially fixed with the transmission bevel gear 14 rotates. The internal threaded cylinder 13 causes the external threaded rod 28 to move linearly along the square rod 11 through threaded transmission, that is, each external threaded rod 28 synchronously moves linearly toward the center of the second fixed frame 9 until the external threaded rod 28 contacts the pipe to complete clamping, the first servo motor 3 rotates the first cardan shaft 6 through the output shaft, and the first cardan shaft 6 causes the roller 21 located at the same end position and equipped with the second cardan shaft 7 to rotate. Since two of the two adjacent second fixed frames 9 are opposite to each other, The rollers 21 are fixed with a second universal shaft 7, and each second universal shaft 7 is located at the same position, so that one of the rollers 21 in each second fixed frame 9 rotates synchronously, and the roller 21 moves the pipe by friction. Since the central axis of the roller 21 intersects with the central axis of the second fixed frame 9 in a non-planar manner, the pipe rotates and moves forward; the inner screw barrel 26 is rotated, and the inner screw barrel 26 moves the second concave block 27 on the external threaded rod 28 through the form of bolt transmission, thereby adjusting the reciprocating spacing of the round wheel 37, so that the third servo motor 46 is started, the third servo motor 46 causes the power rod 25 to rotate axially through the output shaft, the tension spring 32 pulls the toggle plate 33, so that the central axis of the circular wheel 37 intersects with the central axis of the power rod 25 in different planes, and the power rod 25 causes the circular wheel 37 to move linearly along the power rod 25 through friction. When the circular saw machine 45 and the pipe move linearly in the same direction and speed, when the contact wheel 47 on the moving plate 40 contacts the rotating plate 57 on the tilted end of the guide plate 54, the rotating plate 57 cannot rotate due to the restriction of the limit plate 59 (such as Fig.10As shown in the figure, the contact wheel 47 moves downward, and the contact wheel 47 pushes the movable plate 40 downward through the vertical plate 60, and the movable plate 40 compresses the reset spring 42, and the circular saw of the circular saw machine 45 contacts the pipe. Since the circular saw machine 45 and the pipe move at the same speed in the straight direction, and since the pipe rotates and moves forward, the pipe rotates relative to the circular saw machine 45, and the circular saw machine 45 performs circular cutting on the pipe. After the cutting is completed, the contact wheel 47 reaches one end of the guide plate 54, and the reset spring 42 is reset. When the toggle plate 33 is aligned with the first The first contact column 50 on the second concave block 27 pushes the toggle plate 33, and the toggle plate 33 is pushed to another place. The toggle plate 33 toggles the circular wheel 37 to the other side through the rotating rod 35, so that the circular wheel 37 moves in the opposite direction, that is, the circular saw machine 45 is reset. During the resetting process of the circular saw machine 45, the contact contacts with the rotating plate 57, and the rotating plate 57 is pushed without hindering the resetting of the circular saw machine 45 until the toggle plate 33 contacts the second contact column 51 on the other side, thereby repeating the above-mentioned cutting work.
