Description

Technical Field

[0001] This application relates to the field of pipe processing, and in particular to a threaded pipe forming apparatus. Background Technology

[0002] Pipe fittings are widely used in many industries such as construction, manufacturing, and energy. Their processing quality and efficiency directly affect the performance of related products and production benefits.

[0003] In related technologies, threaded pipe forming processes typically employ either roll forming or casting. Roll forming involves pressing the pipe fitting with a roll forming die to create a threaded shape on its surface. This method requires precise die design and manufacturing, and demands significant pressure during the rolling process, placing high demands on the equipment. Casting, on the other hand, involves injecting molten metal into a die with a threaded shape, and then cooling it to obtain the threaded pipe. While this method can produce threaded pipes with complex shapes, it is prone to defects such as porosity and slag inclusions during the casting process, affecting the quality of the threaded pipe.

[0004] In view of the aforementioned technologies, the inventors believe that there is a need to provide another thread forming device with better stability and higher forming efficiency. Utility Model Content

[0005] To improve the stability and efficiency of thread treatment on pipe fittings, this application provides a threaded pipe forming apparatus.

[0006] The threaded tube forming device provided in this application adopts the following technical solution: A threaded pipe forming apparatus includes a mounting frame and a rotary cutting mechanism horizontally slidably arranged on the mounting frame. The mounting frame has a guide rail arranged parallel to the length direction of the pipe and a sliding platform for arranging the rotary cutting mechanism on the guide rail. The bottom of the sliding platform has a guide slider that slides and engages with the guide rail. The rotary cutting mechanism includes a rotary cutting component and a drive motor for driving the rotary cutting component to rotate. The rotary cutting component has a forming channel along its axial direction for the pipe to pass through. The rotary cutting component has a rotary blade for rotary cutting the surface of the pipe, and a cutting head is provided on the side of the rotary blade facing the forming channel. The drive motor has a limiting channel along its output shaft for the pipe to pass through, and the axis of the limiting channel and the axis of the forming channel are both arranged coincidentally with the output shaft of the drive motor. The drive motor has an induction coil, and the mounting frame has an electromagnetic sensor on the side near the rotary cutting component for controlling the start and stop of the drive motor.

[0007] By adopting the above technical solution, when performing thread treatment on the surface of pipe fittings, the operator places the pipe fitting output from the previous stage at the input end of the limit channel of the drive motor. As the pipe fitting output from the previous stage steadily enters the forming channel along the axial direction of the limit channel, the end of the pipe fitting abuts against the cutting head of the rotating blade. The previous stage continues to output pipe fittings and applies a forward thrust to the rotating cutting mechanism. Under the action of the force, the sliding platform at the bottom of the rotating cutting mechanism slides along the length of the guide slide rod towards the side closer to the electromagnetic sensor. When the induction coil in the drive motor moves into the sensing range, the drive motor starts and drives the rotating cutting piece to rotate along the axis of the forming channel. At the same time, the end of the pipe fitting continues to advance at a constant speed along the forming channel. The cutting head rotates coaxially and cuts the surface of the pipe fitting to form threads. The processed threaded pipe is output from the end of the forming channel away from the drive motor, realizing the forming of the threaded pipe and helping to improve the stability and efficiency of the thread treatment on the surface of the pipe fitting.

[0008] Optionally, the number of guide sliders is two, and they are symmetrically arranged at the bottom of the sliding platform along the sliding direction parallel to the sliding platform.

[0009] By adopting the above technical solution, the sliding platform, together with two guide sliders, slides along the guide rod, making the sliding of the sliding platform on the guide rod more stable and balanced, reducing the risk of tilting or shaking, and ensuring the stability of the rotary cutting mechanism during movement, thereby helping to improve the accuracy of threaded tube forming.

[0010] Optionally, the number of guide slide rods is two and they are arranged in parallel on the top of the mounting frame, and the sliding platform has four guide sliders in pairs that cooperate with the two guide slide rods respectively.

[0011] By adopting the above technical solution, two parallel guide slide rods arranged on the top of the mounting frame, together with four guide sliders in pairs on the sliding platform, make the horizontal sliding of the rotary cutting mechanism on the mounting frame more stable and smooth, further improving the operational stability of the threaded pipe forming device and the accuracy of pipe cutting.

[0012] Optionally, the rotary cutting component includes a first rotary seat mounted on the output shaft of the drive motor, a second rotary seat mounted on the side of the first rotary seat away from the drive motor, a connecting member for fixing the first rotary seat and the second rotary seat, and a fixing member for fixing the rotary blade between the first rotary seat and the second rotary seat.

[0013] By adopting the above technical solution, the rotary cutting component adopts a combination structure of a first rotary seat, a second rotary seat, a connecting part and a fixing part, which can more stably install the rotary blade, making the rotary blade more stable when rotary cutting the surface of the pipe, which helps to improve the cutting accuracy and quality, and at the same time facilitates the installation and replacement of the rotary blade.

[0014] Optionally, the connector includes a locking screw arranged through the first rotating seat and the second rotating seat, a first nut for locking the locking screw to the first rotating seat, and a second nut for locking the locking screw to the second rotating seat.

[0015] By adopting the above technical solution, the locking screw passes through the first rotating seat and the second rotating seat, and is locked by the first nut and the second nut respectively, so that the first rotating seat and the second rotating seat are firmly connected, ensuring the stability of the overall structure of the rotating cutting part, and thus ensuring the reliability of the rotating cutting process on the surface of the pipe.

[0016] Optionally, the number of connectors is two, and the two connectors are arranged symmetrically along the axis of the rotating cutter.

[0017] By adopting the above technical solution, the two connecting parts are symmetrically arranged along the axis of the rotating cutting part, making the connection between the first rotating seat and the second rotating seat more stable and the force more uniform. This reduces the risk of the rotating cutting part shaking or shifting during rotation due to uneven force, and helps to improve cutting accuracy and stability.

[0018] Optionally, the fastener includes a first pressure rod that passes through the first rotating seat and abuts against the surface of the rotating blade at one end, a third nut for locking the first pressure rod to the first rotating seat, a second pressure rod that passes through the second rotating seat and abuts against the surface of the rotating blade at one end, and a fourth nut for locking the second pressure rod to the second rotating seat.

[0019] By adopting the above technical solution, the first and second pressure rods pass through the first and second rotating seats respectively and abut against the surface of the rotating blade. Then, the third and fourth nuts are used for locking, so as to firmly fix the rotating blade between the first and second rotating seats. This ensures the stability of the rotating blade when rotating and cutting the pipe fitting, reduces the risk of its position shifting during the cutting process, and thus improves the quality and accuracy of threaded pipe forming.

[0020] Optionally, the number of the fasteners is two, and the two fasteners are arranged symmetrically along the axis of the rotating cutting member.

[0021] By adopting the above technical solution, two fixing components are set up symmetrically along the axis of the rotating cutting part, making the fixing of the rotating blade between the first rotating seat and the second rotating seat more stable and balanced, further reducing the risk of shaking and deviation of the rotating blade during rotating cutting, and helping to further improve the stability and accuracy of cutting.

[0022] Optionally, it also includes a material receiving mechanism installed at the output end of the mounting frame. The material receiving mechanism includes a mounting bracket and a material support plate arranged on the mounting bracket and extending parallel to the length direction of the pipe fitting. Two limiting plates are symmetrically arranged on both sides of the material support plate for limiting the pipe fitting on both sides.

[0023] By adopting the above technical solution, the material receiving mechanism can receive the processed pipe fittings, support the pipe fittings with the material support plate and limit the pipe fittings to the left and right by the symmetrical limiting plates on both sides, which helps to balance the force on the input and output ends of the rotary cutting mechanism, thereby reducing the risk of pipe fittings deviating or shaking during the output process and ensuring the stability and accuracy of pipe fitting output.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. A threaded pipe forming device, comprising a mounting frame and a rotary cutting mechanism; when threading the surface of a pipe, the end of the pipe is first placed at the cutting head of the rotary blade, the pipe is output through the previous step and a forward thrust is applied to the rotary cutting mechanism, under the action of the force, the sliding platform at the bottom of the rotary cutting mechanism slides along the length of the guide slide rod towards the side closer to the electromagnetic sensor, when the induction coil in the drive motor moves into the sensing range, the drive motor starts and drives the rotary cutting part to rotate along the axis of the forming channel, while the end of the pipe continues to move forward at a constant speed along the forming channel, the cutting head rotates coaxially and cuts the surface of the pipe to form threads, and the processed threaded pipe is output from the end of the forming channel away from the drive motor, thus realizing the forming of the threaded pipe, which helps to improve the stability and efficiency of the threading treatment of the pipe surface; 2.

The four guide sliders 121 are paired and slide in cooperation with the two guide slide rods 11. A sliding groove 1211 adapted to the guide slide rod 11 is provided at the bottom of each guide slider 121.

[0036] Reference Figure 2 and Figure 3 The rotary cutting mechanism 2 includes a rotary cutting component 21 and a drive motor 22 for driving the rotary cutting component 21 to rotate. The top of the sliding platform 12 is provided with four supporting columns 122 for accommodating the drive motor 22, ensuring that the output shaft of the drive motor 22 remains horizontal. The drive motor 22 has a limiting channel 221 along the axis of its output shaft for allowing pipe fittings to pass through. An electromagnetic sensor 4 for controlling the start and stop of the drive motor 22 is provided on the mounting frame 1 near the rotary cutting component 21. An induction coil 222 cooperating with the electromagnetic sensor 4 is located inside the drive motor 22. In this embodiment, the drive motor 22 is a three-phase asynchronous motor.

[0037] Reference Figure 4 and Figure 5 The rotary cutting component 21 includes a rotary blade 211 for rotary cutting the surface of a pipe fitting, a first rotary seat 212 mounted on the output shaft of a drive motor 22, a second rotary seat 213 mounted on the side of the first rotary seat 212 away from the drive motor 22, a connecting member 214 for fixing the first rotary seat 212 and the second rotary seat 213, and a fixing member 215 for fixing the rotary blade 211 between the first rotary seat 212 and the second rotary seat 213. The rotary cutting component 21 has a forming channel 216 along its axial direction for the pipe fitting to pass through. The axis of the forming channel 216 coincides with the axis of the limiting channel 221. The rotary blade 211 has a cutting head 2111 on the side facing the forming channel 216 that abuts against the surface of the pipe fitting.

[0038] Reference Figure 6 The connector 214 includes a locking screw 2141 extending through the first rotating seat 212 and the second rotating seat 213, a first nut 2142 for locking the locking screw 2141 to the first rotating seat 212, and a second nut 2143 for locking the locking screw 2141 to the second rotating seat 213. There are two second nuts 2143, symmetrically arranged on both sides of the second rotating seat 213. In this embodiment, there are two connectors 214, and the two connectors 214 are symmetrically arranged along the axis of the rotating cutting member 21.

[0039] ReferenceFigure 7 The fixing member 215 includes a first pressure rod 2151 that passes through the first rotating seat 212 and abuts against the surface of the rotating blade 211 at one end; a third nut 2152 for locking the first pressure rod 2151 to the first rotating seat 212; a second pressure rod 2153 that passes through the second rotating seat 213 and abuts against the surface of the rotating blade 211 at one end; and a fourth nut 2154 for locking the second pressure rod 2153 to the second rotating seat 213.

[0040] The material receiving mechanism 3 includes a mounting bracket 31 and a material support plate 32 arranged on the mounting bracket 31 and extending parallel to the length of the pipe fitting. Two limiting plates 321 are symmetrically arranged on both sides of the material support plate 32 for limiting the pipe fitting on both sides.

[0041] The implementation principle of the threaded pipe forming device in this embodiment is as follows: When threading the surface of the pipe, the operator places the pipe output from the previous stage at the input end of the limiting channel 221 of the drive motor 22. As the pipe output from the previous stage is stable, it slowly enters the forming channel 216 along the axial direction of the limiting channel 221, so that the end of the pipe abuts against the cutting head 2111 of the rotating blade 211. The previous stage continues to output the pipe and applies a forward thrust to the rotating cutting mechanism 2. Under the action of the force, the sliding platform 12 at the bottom of the rotating cutting mechanism 2 moves along the guide. The slide bar 11 slides along the length direction towards the side closer to the electromagnetic sensor 4. When the induction coil 222 inside the drive motor 22 moves into the sensing range, the drive motor 22 starts and drives the rotating cutting piece 21 to rotate along the axis of the forming channel 216. At the same time, the end of the pipe continues to move forward at a constant speed along the forming channel 216. The cutting head 2111 rotates coaxially and cuts the surface of the pipe to form threads. The processed threaded pipe is output from the end of the forming channel 216 away from the drive motor 22, thus realizing the forming of the threaded pipe and helping to improve the stability and efficiency of the thread treatment on the surface of the pipe.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
