Description

Technical Field

[0001] The invention belongs to the technical field of metal pipe processing, and in particular relates to a device for turning the end of a metal pipe into a round shape and a processing method thereof. Background Art

[0002] In modern industry, metal pipes, due to their excellent mechanical properties and corrosion resistance, are widely used in key industries such as petrochemicals, energy transportation, and urban water supply and drainage. During the installation and connection of piping systems, the roundness of metal pipe ends is a key indicator for ensuring the tightness, stability, and overall operational reliability of the connection. If the pipe ends are not round, they can cause misalignment and reduced sealing effectiveness. This can not only easily lead to media leakage, waste resources, and environmental pollution, but can also cause safety accidents under high-pressure and high-temperature conditions.

[0003] However, when rounding the ends of metal pipes, a turning tool is often used to round one end of the metal pipe first. After the rounding is completed, the metal pipe is taken out, and then the direction is changed and the pipe is re-clamped and positioned. Then the turning tool is used to round the other end of the metal pipe. This makes it more troublesome to change the direction back and forth. Moreover, when the rounding is completed, there will often be debris left on the metal pipe. When the worker picks it up again, the debris is likely to get stuck in his hand, causing injury.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0017] As a preferred embodiment of the present invention, a method for turning a metal pipe end into a full circle comprises the following steps:

[0018] Step 1: First, the staff opens the sliding door on the machine tool body and places the metal tube body into the circular slot in the middle of the protective shell. At this time, the staff controls the electric push rod through the controller to move, and the electric push rod drives the two clamping plates to clamp the metal tube body.

[0019] Step 2: The staff controls the operation of the driving assembly through the controller, so that the driving assembly can first drive the circular moving cylinder to move, thereby separating the first bevel gear and the second bevel gear ring. At the same time, the driving assembly continues to move to drive the circular turntable to rotate, thereby rotating the protective shell, thereby driving the metal tube body to rotate 180 degrees. At this time, the first bevel gear can be reset, thereby ensuring that the first bevel gear can mesh with the second bevel gear ring.

[0020] Step 3: When the circular movable cylinder moves vertically, it can also drive the circular cleaning cylinder away from the metal pipe body. When the circular movable cylinder is reset, the circular cleaning cylinder can enter the metal pipe body, so that when the metal pipe body rotates, the circular cleaning cylinder can clean its surface.

[0021] Step 4: At this time, the staff controls the turning tool to move on the track, thereby adjusting the position between the turning tool and the metal tube body, ensuring that when the metal tube body rotates, the end of the metal tube body can be turned into a full circle.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention can turn the end of one end of the metal tube body into a full circle after turning the end of the metal tube body. At this time, the driving component can be used to control the metal tube body to change direction. When the metal tube body is changed in direction, the driving component can continue to move to allow the circular cleaning cylinder to be sleeved on the end of the metal tube body that has been processed. At this time, by adjusting the turning tool to the end of the metal tube body that has not been processed and controlling the rotation of the metal tube body, the turning tool can be used to turn the end of the metal tube body into a full circle, and the other end can be cleaned, ensuring that when turning the two ends of the metal tube body into a full circle, it is not necessary to take it out and then perform the reversing operation, and ensuring that it can be kept relatively clean when the full circle is completed.

After turning one end of the metal tube body 5 into a full circle, the metal tube body 5 can be controlled to reverse by the driving component. When the reversal of the metal tube body 5 is completed, the driving component can continue to move to allow the circular cleaning cylinder 42 to be sleeved on the processed end of the metal tube body 5. At this time, by adjusting the turning tool 113 to the unprocessed end of the metal tube body 5 and controlling the rotation of the metal tube body 5, the turning tool 113 can be used to turn the end of the metal tube body 5 into a full circle, and the other end can be cleaned, ensuring that when turning the two ends of the metal tube body 5 into a full circle, there is no need to take it out and then perform the reversing operation, and ensuring that it can be kept relatively clean when the full circle is completed.

[0053] like Figures 1 to 5 As shown, in a specific embodiment, a base 111 is provided at the bottom of the machine tool body 1, and a sliding door 11 is provided at the front side of the machine tool body 1. In this configuration, the installation position and components of the machine tool body 1.

[0054] like Figures 6 and 7 and Figures 9 to 16As shown, further, a circular mounting ring 323 is rotatably mounted on the inner wall of the protective housing 3. A second bevel gear ring 322 is sleeved on the outer ring of the circular mounting ring 323. A first bevel gear 321 is vertically meshed with the second bevel gear ring 322. A servo motor 32 is mounted on the first bevel gear 321. The output end of the servo motor 32 is connected to the first bevel gear 321. A circular moving cylinder 312 is mounted on the servo motor 32. A fixed block 313 is mounted on the circular moving cylinder 312. An L-shaped mounting plate 22 and a movable plate 4 are mounted on the fixed block 313. The L-shaped mounting plate 22 movably passes through the placement plate 114. In this configuration, the installation positions of the first bevel gear 321 and the second bevel gear ring 322 are determined.

[0055] like Figures 6 and 7 and Figures 9 to 16 As shown, a circular protective cylinder 31 is rotatably mounted on the protective housing 3. Two symmetrical connecting rods 311 are mounted on the circular protective cylinder 31. The ends of the two connecting rods 311, which are located away from the circular protective cylinder 31, are mounted on the inner wall of the machine tool body 1. The circular protective cylinder 31 and the circular movable cylinder 312 are slidably mounted. This arrangement defines the relationship between the circular protective cylinder 31 and the protective housing 3, as well as the relationship between the circular protective cylinder 31 and the circular movable cylinder 312.

[0056] like Figures 6 to 16 As shown, the drive assembly further includes a hydraulic cylinder 2, one end of which is mounted on the inner wall of the machine tool body 1. A wedge block 21 is provided at the output end of the hydraulic cylinder 2. An L-shaped mounting plate 22 is fitted onto the inclined surface of the wedge block 21, which faces away from the hydraulic cylinder 2. An L-shaped fixing plate 221 is provided on one side wall of the L-shaped mounting plate 22. A Z-shaped mounting plate 224 is provided on the end of the L-shaped fixing plate 221, which faces away from the L-shaped mounting plate 22. A tilting block 223 is provided between the L-shaped fixing plate 221 and the Z-shaped mounting plate 224. This configuration defines the installation position and components of the drive assembly.

[0057] Example 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 6 to 16 The figure shows a device for turning the ends of metal pipes into full circles. A rotating rod 23 is disposed at the bottom of a circular turntable 236. The rotating rod 23 is rotatably mounted at the bottom of the inner cavity of the machine tool body 1. A spiral notch 231 is formed on the rotating rod 23, and a sliding block 232 is slidably mounted on the spiral notch 231. A guide rod 233 is provided through the sliding block 232 and the Z-shaped mounting plate 224. This arrangement ensures that the rotating rod 23 can be rotated when the sliding block 232 moves.

[0058] like Figures 6 to 16As shown, in this embodiment, one end of a guide rod 233 is mounted on the inner wall of the machine tool body 1, and a limit ring 234 is mounted on the upper end of the guide rod 233. A return spring 235 is mounted on the limit ring 234, and one end of the return spring 235 is mounted on the sliding block 232. This arrangement ensures that when the wedge block 21 is reset, the sliding block 232 can be reset with the assistance of the return spring 235, thereby resetting the rotating rod 23.

[0059] like Figures 6 to 16 As shown, further, a concave mounting plate 24 is provided on the sliding block 232, and a positioning plate 241 is provided at the bottom of one end of the concave mounting plate 24 away from the sliding block 232. In this arrangement, the installation position of the positioning plate 241 is determined.

[0060] like Figures 1 to 15 As shown, a swing arm 41 is further provided at the bottom of the end of the movable plate 4 away from the fixed block 313, and the swing arm 41 is mounted on a circular cleaning cylinder 42. A placement slot 421 is provided through one side wall of the inner cavity of the circular cleaning cylinder 42, and a scraper 422 is also provided on the inner wall of the circular cleaning cylinder 42. This arrangement ensures that when the metal tube body 5 rotates, the scraper 422 provided in the circular cleaning cylinder 42 can clean its surface. At the same time, the cleaned impurities can fall from the placement slot 421 provided in the circular cleaning cylinder 42, thereby ensuring the cleanliness of the metal tube body 5 after processing.

[0061] In Example 3, the present invention further discloses a method for turning a metal pipe end into a full circle, the steps of which are as follows:

[0062] Step 1: First, the staff opens the sliding door 11 on the machine tool body 1 and places the metal tube body 5 into the circular notch in the middle of the protective shell 3. At this time, the staff controls the electric push rod 33 through the controller to move, so that the electric push rod 33 drives the two clamping plates 331 to clamp the metal tube body 5.

[0063] Step 2: The staff controls the operation of the driving assembly through the controller, so that the driving assembly can first drive the circular moving cylinder 312 to move, thereby separating the first bevel gear 321 and the second bevel gear ring 322. At the same time, the driving assembly continues to move to drive the circular turntable 236 to rotate, thereby rotating the protective shell 3, thereby driving the metal tube body 5 to rotate 180 degrees. At this time, the first bevel gear 321 can be reset, thereby ensuring that the first bevel gear 321 can mesh with the second bevel gear ring 322.

[0064] Step 3: When the circular movable cylinder 312 moves vertically, it can also drive the circular cleaning cylinder 42 away from the metal pipe body 5. When the circular movable cylinder 312 is reset, the circular cleaning cylinder 42 can enter the metal pipe body 5, so that the surface of the metal pipe body 5 can be cleaned by the circular cleaning cylinder 42 when the metal pipe body 5 rotates.

[0065] Step 4: At this time, the staff controls the turning tool 113 to move on the track 112, thereby adjusting the position between the turning tool 113 and the metal tube body 5, ensuring that when the metal tube body 5 rotates, the end of the metal tube body 5 can be turned into a full circle.

[0066] The implementation principles of a metal pipe end turning device and processing method of this embodiment are as follows:

[0067] First, the staff opens the sliding door 11 and places the metal tube body 5 into the inner cavity of the machine tool body 1. When the placement is completed, the staff controls the electric push rod 33 through the controller to operate, so that the electric push rod 33 can push the clamping plate 331 to clamp and position the placed metal tube body 5;

[0068] At the same time, the staff controls the operation of the hydraulic cylinder 2, so that the hydraulic cylinder 2 can push the wedge block 21 to move horizontally. When the wedge block 21 moves horizontally, it can first squeeze the L-shaped mounting plate 22, which can move vertically upward with the assistance of the inclined surface of the wedge block 21 (because the L-shaped mounting plate 22 is movable through the placement plate 114). When the L-shaped mounting plate 22 moves vertically upward, it can drive the fixed block 313 to move. When the fixed block 313 moves, it can drive the circular moving cylinder 312 to move. Because the inner cavity of the circular moving cylinder 312 is provided with a servo motor, the circular moving cylinder 312 can move vertically upward. The servo motor 32 is driven by the servo motor 32, thereby driving the servo motor 32 to move vertically upward, thereby driving the first bevel gear 321 to move vertically upward, separating the first bevel gear 321 from the second bevel gear ring 322. At this time, the first bevel gear 321 can enter the inner cavity of the circular protective cylinder 31 (when the fixed block 313 moves vertically upward, it can drive the movable plate 4 to move vertically upward, thereby driving the swing arm 41 to move through the movable plate 4, thereby pulling the circular cleaning cylinder 42 horizontally away from the metal pipe body 5 with the assistance of the telescopic rod 43);

[0069] At the same time, when the L-shaped mounting plate 22 moves, it will be able to drive the L-shaped fixing plate 221 and the inclined block 223 to move vertically upward until the wedge block 21 passes through and contacts the positioning plate 241. At this time, the wedge block 21 continues to move, so the wedge block 21 can squeeze the positioning plate 241 through the inclined surface to drive the concave mounting plate 24 to move vertically upward with the assistance of the sliding block 232 and the guide rod 233. When the sliding block 232 moves vertically upward, the spiral groove 231 opened on the rotating rod 23 can be used to rotate the rotating rod 23. When the rotating rod 23 rotates, it can bring The circular turntable 236 rotates, thereby driving the protective housing 3 to rotate. When the protective housing 3 rotates, it drives the circular mounting ring 323 to rotate. When the circular mounting ring 323 rotates, it drives the electric push rod 33 and the clamping plate 331 to rotate, thereby driving the metal pipe body 5 clamped by the clamping plate 331 to rotate (because a connecting rod 311 is provided above the circular protective cylinder 31 and the connecting rod 311 is provided on the inner wall of the machine tool body 1, thus ensuring that the circular protective cylinder 31 does not rotate with the protective housing 3);

[0070] When the wedge block 21 continues to move horizontally, the positioning plate 241 will be located on the horizontal surface above the wedge block 21. At the same time, when the wedge block 21 moves horizontally, the inclined block 223 can slowly move downward with the assistance of the inclined surface of the wedge block 21. When the inclined block 223 can move downward, it will be able to drive the L-shaped fixing plate 221 to move vertically downward. When the L-shaped fixing plate 221 moves vertically downward, it will be able to drive the L-shaped mounting plate 22 to move vertically downward. When the L-shaped mounting plate 22 moves vertically downward, it will be able to drive the fixing block 313 to move vertically downward, thereby driving the circular moving cylinder 312 to move vertically downward, allowing the first bevel gear 321 to reset and engage with the second bevel gear ring 322 after rotating 180 degrees.

[0071] After rotating 180 degrees, the staff controls the turning tool 113 to move and debug on the track 112 until the turning tool 113 is located at the end of the metal tube body 5. At this time, the staff controls the servo motor 32 to drive the first bevel gear 321 to rotate. Because the first bevel gear 321 and the second bevel gear ring 322 are engaged at this time, the second bevel gear ring 322 can be rotated. When the second bevel gear ring 322 rotates, it can drive the metal tube body 5 to rotate, thereby turning the end of the metal tube body 5 into a full circle (at the same time, when the fixed block When 313 moves vertically downward, it can also drive the movable plate 4 to move vertically downward. When the movable plate 4 moves vertically downward, it can drive the swing arm 41 to move, so that the circular cleaning cylinder 42 can be driven by the swing arm 41 to insert into the end of the metal tube body 5. At this time, when the metal tube body 5 rotates, the scraper 422 provided in the circular cleaning cylinder 42 can clean its surface. At the same time, the cleaned impurities can fall from the placement slot 421 opened at the circular cleaning cylinder 42, thereby ensuring the cleanliness of the processed metal tube body 5).
