Technical Field

[0001] This utility model relates to the field of welded steel pipe processing technology, specifically to a mold capable of removing the inner weld bead of a welded steel pipe. Background Technology

[0002] Internal weld bead refers to the protrusions formed inside the steel pipe through fusion welding. During the production process, the weld bead on the inner wall of the steel pipe needs to be removed before the steel pipe can be welded. In the existing technology, the internal weld bead is generally processed by a special processing mold.

[0003] However, many internal weld bead removal devices, while capable of removing the internal weld bead, have limitations in use because different steel pipes have different diameters, and the devices cannot be adjusted according to the inner diameter of the steel pipe.

[0004] In view of this, the present invention proposes a mold capable of removing the inner weld bead of a welded steel pipe. Utility Model Content

[0005] This utility model proposes a mold that can remove the inner weld bead of welded steel pipes, solving the problem that many existing inner weld bead processing devices, while achieving the purpose of removing the inner weld bead, cannot adjust their size according to the inner diameter of different steel pipes, thus having certain limitations in use.

[0006] The technical solution of this utility model is as follows: A mold capable of removing the inner weld bead of a welded steel pipe includes a base. A first side plate is fixedly connected to the top of the base. A servo motor is fixedly connected to the right side of the first side plate. A screw is fixedly connected to the output end of the servo motor. A second side plate is threadedly connected to the surface of the screw. A first connecting plate is fixedly connected to the left side of the second side plate. A limiting rod fixedly connected to the first side plate is slidably connected inside the second side plate. A transmission motor is fixedly connected to the left side of the first connecting plate. A connecting plate is fixedly connected to the output end of the transmission motor. An installation plate is fixedly connected to the left side of the connecting plate. A control ring is rotatably connected to one side of the installation plate. A second connecting plate is rotatably connected to the surface of the control ring. A grinding ring is rotatably connected to the surface of the second connecting plate. A cutting ring is fixedly connected to the left side of the grinding ring. A telescopic column fixedly connected to the installation plate is fixedly connected to one end of the grinding ring. A groove is provided inside the installation plate. An adjusting rod fixedly connected to the control ring is slidably connected inside the groove. A nut is threadedly connected to the surface of the adjusting rod.

[0007] Preferably, a limiting plate is slidably connected inside the base, a base plate is fixedly connected to the bottom of the limiting plate, and an electric push rod with an output end fixedly connected to the base is fixedly connected to the top of the base plate.

[0008] Preferably, the second side plate is tightly fitted to the limiting rod, and the second side plate slides horizontally along the limiting rod via a screw.

[0009] Preferably, the control ring and the center of the mounting plate are located at the same point, and the second connecting plate is inclined.

[0010] Preferably, the connection between the second connecting plate and the grinding ring is located at the top end of the second connecting plate, and the grinding ring forms a telescopic structure through the second connecting plate.

[0011] Preferably, three sets of grinding rings are symmetrically arranged about the center of the mounting plate, and the telescopic columns are arranged perpendicular to the grinding rings.

[0012] Preferably, the cutting ring is arranged in an arc shape on one side of the grinding ring, and the left side of the cutting ring is designed to be sharp.

[0013] Preferably, an electric push rod is provided at each of the four diagonal corners of the base, and the base forms a horizontal lifting structure through the electric push rods.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] In this invention, a control ring is provided. Since different steel pipes have different inner diameters, the control ring can be rotated before the grinding ring enters the steel pipe. When it rotates clockwise, it pushes the grinding ring through the second connecting plate. At this time, under the limit of the telescopic column, the grinding ring will move horizontally away from the mounting plate, thereby achieving the purpose of adjusting the grinding ring and processing steel pipes of different diameters. Since the control ring rotates, it will simultaneously drive the adjusting rod to move inside the slide groove. Therefore, when the adjusting rod is fixed by the nut, the control ring will also be fixed, thereby fixing the grinding ring.

[0016] 2. In this utility model, by setting a grinding ring, the servo motor is turned on to control the screw to rotate. At this time, the second side plate will slide to the left along the surface of the limit rod, so that the grinding ring enters the interior of the steel pipe. The transmission motor is turned on to control the connecting plate to rotate. When it rotates, it will drive the mounting plate to rotate synchronously, and thus drive the grinding ring and the cutting ring to move. When the grinding ring rotates, it will grind the inner wall of the steel pipe. Since the tail of the cutting ring is sharp, it can cut off the inner weld rib inside the steel pipe while rotating and moving. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0024] A preferred embodiment of the mold for removing the inner weld bead of a welded steel pipe provided by this utility model is, for example... Figures 1 to 4 As shown: A mold capable of removing the inner weld bead of a welded steel pipe includes a base 1. A first side plate 2 is fixedly connected to the top of the base 1. A servo motor 4 is fixedly connected to the right side of the first side plate 2. A screw 5 is fixedly connected to the output end of the servo motor 4. A second side plate 3 is threadedly connected to the surface of the screw 5. A first connecting plate 6 is fixedly connected to the left side of the second side plate 3. A limiting rod 7, which is fixedly connected to the first side plate 2, is slidably connected inside the second side plate 3. A drive motor 8 is fixedly connected to the left side of the first connecting plate 6. A connecting plate 9 is fixedly connected to the output end of the drive motor 8. A mounting plate 10 is fixedly connected to the left side of the mounting plate 10. A control ring 11 is rotatably connected to one side of the mounting plate 10. A second connecting plate 12 is rotatably connected to the surface of the control ring 11. A grinding ring 13 is rotatably connected to the surface of the second connecting plate 12. A cutting ring 14 is fixedly connected to the left side of the grinding ring 13. A telescopic column 15, which is fixedly connected to the mounting plate 10, is fixedly connected to one end of the grinding ring 13. A sliding groove 16 is provided inside the mounting plate 10. An adjusting rod 17, which is fixedly connected to the control ring 11, is slidably connected inside the sliding groove 16. A nut 18 is threadedly connected to the surface of the adjusting rod 17.

[0025] In this embodiment, the second side plate 3 is tightly fitted with the limiting rod 7. The second side plate 3 slides horizontally along the limiting rod 7 via the screw 5. The servo motor 4 is turned on to control the screw 5 to rotate. At this time, the second side plate 3 will slide to the left along the surface of the limiting rod 7, so that the grinding ring 13 enters the interior of the steel pipe.

[0026] In this embodiment, the control ring 11 and the center of the mounting plate 10 are located at the same point. The second connecting plate 12 is inclined. When the control ring 11 is rotated clockwise, it will push the grinding ring 13 through the second connecting plate 12. At this time, under the limit of the telescopic column 15, the grinding ring 13 will move horizontally away from the mounting plate 10.

[0027] In this embodiment, the connection between the second connecting plate 12 and the grinding ring 13 is located at the top end of the second connecting plate 12. The grinding ring 13 forms a telescopic structure through the second connecting plate 12. By setting the second connecting plate 12, the rotational force of the control ring 11 can be converted into a thrust on the grinding ring 13.

[0028] In this embodiment, three sets of grinding rings 13 are symmetrically arranged about the center of the mounting plate 10. The telescopic column 15 is perpendicular to the grinding rings 13. When the drive motor 8 is turned on, it controls the connecting plate 9 to rotate. When it rotates, it will drive the mounting plate 10 to rotate synchronously, thereby driving the grinding rings 13 and the cutting ring 14 to move. When the grinding rings 13 rotate, they will grind the inner wall of the steel pipe.

[0029] In this embodiment, the cutting ring 14 is arranged in an arc shape on one side of the grinding ring 13. The left side of the cutting ring 14 is designed to be sharp. Since the tail of the cutting ring 14 is sharp, the inner weld bead inside the steel pipe can be cut off while rotating and moving. Example 2

[0030] Based on Example 1, a preferred embodiment of the mold for removing the inner weld bead of a welded steel pipe provided by this utility model is, for example... Figures 1 to 4 As shown: a limiting plate 19 is slidably connected inside the base 1, a base plate 20 is fixedly connected to the bottom of the limiting plate 19, and an electric push rod 21 with its output end fixedly connected to the base 1 is fixedly connected to the top of the base plate 20.

[0031] In this embodiment, electric push rods 21 are provided at the four diagonal corners of the base 1. The base 1 forms a horizontal lifting structure through the electric push rods 21. When the electric push rods 21 are opened, they drive the base 1 to rise horizontally along the limiting plate 19, thereby driving the first side plate 2 to rise. At this time, the position of the grinding ring 13 will also move accordingly, thereby adjusting it to the position corresponding to the steel pipe.

[0032] The working principle and usage process of this utility model are as follows: First, when it is necessary to remove the inner weld ribs of the steel pipe, turn on the electric push rod 21, which drives the base 1 to rise horizontally along the limiting plate 19, thereby driving the first side plate 2 to rise. At this time, the position of the grinding ring 13 will also move accordingly, thereby adjusting it to the position corresponding to the steel pipe. Then, turn on the servo motor 4 to control the screw 5 to rotate. At this time, the second side plate 3 will slide to the left along the surface of the limiting rod 7, allowing the grinding ring 13 to enter the interior of the steel pipe. Turn on the transmission motor 8 to control the connecting plate 9 to rotate. When it rotates, it will drive the mounting plate 10 to rotate synchronously, thereby driving the grinding ring 13 and the cutting ring 14 to move. When the grinding ring 13 rotates, it will grind the inner wall of the steel pipe. Due to the cutting... The tail of ring 14 is sharpened, so it can cut off the inner weld ribs inside the steel pipe while rotating and moving. Since different steel pipes have different inner diameters, the control ring 11 can be rotated before the grinding ring 13 enters the steel pipe. When it rotates clockwise, it will push the grinding ring 13 through the second connecting plate 12. At this time, under the limit of the telescopic column 15, the grinding ring 13 will move horizontally away from the mounting plate 10, thereby achieving the purpose of adjusting the grinding ring 13 and processing steel pipes of different diameters. Since the adjustment rod 17 will move inside the slide groove 16 synchronously when the control ring 11 rotates, the control ring 11 will also be fixed when the adjustment rod 17 is fixed by the nut 18, thereby fixing the grinding ring 13.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
