Description
Technical Field
[0001] This utility model relates to the field of steel pipe guiding technology, specifically a guiding device for processing and forming seamless steel pipes. Background Technology
[0002] Seamless steel pipes are an important basic industrial material and are widely used in petroleum, chemical, machinery manufacturing, aerospace and other fields. During their processing, steel pipes need to be guided by a guide device to constrain their movement trajectory in order to avoid defects such as bending, out-of-tolerance ovality, and surface scratches caused by radial offset, vibration or friction damage.
[0003] Traditional guiding devices often use fixed guide sleeves or unidirectional guide roller structures, which easily lead to sliding friction between the steel pipe and the guiding components, causing scratches on the surface of the steel pipe. At the same time, the lack of a reasonable lubrication structure design makes it difficult for the lubricant to act evenly on the contact surface, resulting in rapid wear of the guiding components and shortening the service life of the equipment. Utility Model Content

[0009] Preferably, the inner walls of the lower guide block and the upper guide block are rotatably connected to a rotating wheel, the outer wall of the rotating wheel is fixedly connected to a sealing sleeve, the outer wall of the sealing sleeve is provided with a groove, the inner walls of the lower guide block and the upper guide block are provided with an oil cavity, the outer walls of the lower guide block and the upper guide block are symmetrically provided with an oil injection port, and the inner wall of the oil injection port is slidably connected to a plug.
[0010] Preferably, the rotating wheels are arranged in an array along the inner walls of the lower and upper guide blocks, and the grooves are arranged in a ring around the central point of the sealing sleeve. The rotation of the rotating wheels converts the sliding friction of the steel pipe into rolling friction, reducing scratches on the surface of the steel pipe.

[0011] Preferably, the interior of the oil inlet is connected to the interior of the oil cavity, and the interior of the groove is connected to the interior of the oil cavity. Lubricant can be added to the oil cavity through the oil inlet. The plug is used to seal the oil inlet to prevent lubricant leakage or impurities from entering. The lubricant automatically seeps into the contact surface between the steel pipe and the rotating wheel when the wheel rotates through the connecting structure between the oil cavity and the groove, forming an oil film to reduce friction and wear.
[0012] Preferably, the support structure includes a base, the inner wall of which is provided with a lifting groove, the inner wall of which is symmetrically provided with guide grooves, and a knob is rotatably connected to the inner wall of the base, and the knob is located above the lifting groove.

When the knob is rotated, since its inner wall is threadedly connected to the lifting threaded rod, and the lower guide block is slidably connected to the guide groove of the support structure through the guide rod, the lower guide block will drive the entire guide structure to move up and down along the lifting groove.
[0014] (III) Beneficial Effects
[0015] This utility model provides a guiding device for processing and forming seamless steel pipes. It has the following features:
[0016] Beneficial effects:
[0017] (i) The roller, through the sealing sleeve on the outer wall, contacts the outer wall of the steel pipe, converting sliding friction into rolling friction, effectively reducing scratches on the surface of the steel pipe and protecting the appearance quality of the steel pipe. At the same time, the multi-directionally distributed rollers can constrain the radial displacement of the steel pipe from multiple angles. Combined with the stable sliding cooperation of the support structure and the guide structure, it ensures that the steel pipe moves in a straight line during processing. The lubrication system composed of oil chamber, oil injection port and groove can make the lubricant automatically penetrate into the contact surface to form an oil film when the roller rotates, which greatly reduces the friction and wear between the roller and the steel pipe.
[0018] (II) This guide structure can flexibly adjust the vertical distance between the lower guide block and the upper guide block by adjusting the threaded transmission of the threaded rod. Combined with the synergistic effect of the lifting threaded rod and the knob, it can achieve overall height adjustment and accurately adapt to the processing needs of seamless steel pipes with different diameters and different height positions.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 This utility model provides a technical solution: a guiding device for processing and forming seamless steel pipes, comprising: a support structure 1, a guiding structure 2 slidably connected to the inner wall of the support structure 1; the guiding structure 2 includes a lower guide block 21, an adjusting threaded rod 22 symmetrically rotatably connected to the outer wall of the top of the lower guide block 21, an upper guide block 23 threadedly connected to the outer wall of the adjusting threaded rod 22, a guide rod 24 symmetrically fixedly connected to the outer wall of the bottom of the lower guide block 21, and a lifting threaded rod 25 fixedly connected to the outer wall of the bottom of the lower guide block 21.
[0028] The inner walls of the lower guide block 21 and the upper guide block 23 are rotatably connected to a rotating wheel 26. The outer wall of the rotating wheel 26 is fixedly connected to a sealing sleeve 27. The outer wall of the sealing sleeve 27 has a groove 28. The inner walls of the lower guide block 21 and the upper guide block 23 are both provided with an oil cavity 29. The outer walls of the lower guide block 21 and the upper guide block 23 are symmetrically provided with an oil inlet 291. The inner wall of the oil inlet 291 is slidably connected to a plug 292.
[0029] The rotating wheel 26 is arranged in an array along the inner wall of the lower guide block 21 and the upper guide block 23. The groove 28 is arranged in a ring along the central point of the sealing sleeve 27. The rotation of the rotating wheel 26 converts the sliding friction of the steel pipe into rolling friction, reducing scratches on the surface of the steel pipe. It can also constrain the radial displacement of the steel pipe from multiple directions, ensuring that the steel pipe moves in a straight line.
[0030] The interior of the oil inlet 291 is connected to the interior of the oil cavity 29, and the interior of the groove 28 is connected to the interior of the oil cavity 29. Lubricant can be added to the oil cavity 29 through the oil inlet 291. The plug 292 is used to seal the oil inlet 291 to prevent lubricant leakage or impurities from entering. The lubricant automatically seeps into the contact surface between the steel pipe and the rotating wheel 26 when the wheel 26 rotates through the connecting structure between the oil cavity 29 and the groove 28, forming an oil film to reduce friction and wear.
[0031] The support structure 1 includes a base 11, a lifting groove 12 is provided on the inner wall of the base 11, guide grooves 13 are symmetrically provided on the inner wall of the base 11, and a knob 14 is rotatably connected to the inner wall of the base 11, and the knob 14 is located above the lifting groove 12.
[0032] The outer wall of the adjusting threaded rod 22 is threadedly connected to the inner wall of the knob 14. The outer wall of the bottom of the adjusting threaded rod 22 is slidably connected to the inner wall of the lifting groove 12. The outer wall of the guide rod 24 is slidably connected to the inner wall of the guide groove 13. When the knob 14 is rotated, since its inner wall is threadedly connected to the lifting threaded rod 25, and the lower guide block 21 is slidably connected to the guide groove 13 of the support structure 1 through the guide rod 24, the lower guide block 21 will drive the entire guide structure 2 to move up and down along the lifting groove 12.
[0033] In use, the device is fixedly installed on the outer wall of the steel pipe processing line via the base 11 on the support structure 1 to provide stable support. The guide structure 2 slides along the inner wall of the support structure 1 to achieve coordinated operation of position adjustment and steel pipe guidance.
[0034] The guide structure 2 adapts to seamless steel pipes of different diameters and heights by adjusting the threaded rod 22 and the lifting threaded rod 25. When the adjusting threaded rod 22 is rotated, the upper guide block 23 moves up and down along the axis of the adjusting threaded rod 22 because the upper guide block 23 is threadedly connected to the adjusting threaded rod 22 and the lower guide block 21 is rotatably connected to the adjusting threaded rod 22. This changes the distance between the lower guide block 21 and the upper guide block 23. When processing steel pipes with larger diameters, rotating the adjusting threaded rod 22 moves the upper guide block 23 upward, increasing the vertical distance; conversely, rotating it reduces the distance until it matches the outer diameter of the steel pipe.
[0035] When the knob 14 is rotated, its inner wall is threadedly connected to the lifting threaded rod 25, and the lower guide block 21 is slidably connected to the guide groove 13 of the support structure 1 through the guide rod 24. The lower guide block 21 will drive the entire guide structure 2 to move up and down along the lifting groove 12, so as to achieve the height alignment between the guide structure 2 and the seamless steel pipe processing line.
[0036] Once the spacing and height are set, the seamless steel pipe passes through the gap between the lower guide block 21 and the upper guide block 23. At this time, the inner wall of the rotating wheel 26 contacts the outer wall of the steel pipe. The rotation of the rotating wheel 26 converts the sliding friction of the steel pipe into rolling friction, reducing scratches on the surface of the steel pipe. The rotating wheel 26 is arranged in an array along the inner wall of the lower guide block 21 and the upper guide block 23, which can constrain the radial displacement of the steel pipe from multiple directions, ensuring that the steel pipe moves in a straight line.
[0037] The oil cavity 29 is used to store lubricant. Lubricant can be added to the oil cavity 29 through the oil inlet 291. The plug 292 is used to seal the oil inlet 291 to prevent lubricant leakage or impurities from entering. The lubricant automatically seeps into the contact surface between the steel pipe and the roller 26 when the roller 26 rotates through the communication structure between the oil cavity 29 and the groove 28, forming an oil film to reduce friction and wear. At the same time, the sealing sleeve 27 can prevent lubricant from overflowing and contaminating the processing environment, and block impurities such as iron filings from entering the guide gap.
