Description

Technical Field

[0001] This invention relates to the field of seamless steel pipe laying technology, and more particularly to a laying device for cold-drawn stainless steel seamless steel pipes. Background Technology

[0002] Stainless steel seamless pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It has a wide range of applications. It can be used for fluid transportation, such as in oil, natural gas, chemical, and power industries, to ensure the normal flow of fluids and prevent losses caused by pipeline leaks. Cold drawing is an important manufacturing process for stainless steel seamless pipe, mainly used to improve the dimensional accuracy and surface quality of the steel pipe.

[0003] Patent publication number CN 208712542 U discloses a tube-dropping device for cold-drawing stainless steel seamless steel pipes. The device can easily move the steel pipes to a specified height, avoiding the need for manual handling of the material. The device is convenient to use, but the material may fall during the lifting process. In addition, the device can only perform single-piece loading, and cannot automatically load large quantities of material one by one.

[0004] Patent publication number CN 207463837 U discloses a tube dropping device for cold drawing of stainless steel seamless steel pipe. The device can achieve the effect of collecting materials on both sides through the transition plates on both sides. However, in order to fix the position of the transition plates on both sides, the slope of the tube dropping cannot be adjusted according to the actual situation. Furthermore, the plate surface is used for material dropping, and the contact area between the steel pipe and the transition plate is large, which can easily generate greater resistance or cause the steel pipe to move unsmoothly.

[0005] To address this, a tube-dropping device for cold-drawing stainless steel seamless pipes is proposed. Summary of the Invention

[0019] This solution uses a first lead screw to drive the movement of the movable block, thereby adjusting the angle of the adjusting plate. The sliding tube facilitates a smoother descent of the steel pipe, avoiding excessive friction during the fall. A lubrication structure allows for the application and even wiping of lubricant on the outer surface of the sliding tube. After wiping, the movement of the first insert rod drives the rotation of the outer sleeve rod, raising the position of the lubricating strip and preventing obstruction of the steel pipe during unloading. The connection between the positioning plate and the positioning rod fixes the position of the connecting rod, allowing the steel pipe to fall directly. The lifting plate transports the steel pipes upwards one by one, and its slight incline prevents the pipes from falling. The outer and inner limit frames ensure greater stability during the lifting process. The rotation of the rotating rollers allows for the transport of only one material at a time, facilitating the stacking and loading of large quantities of materials.

[0020] This solution reduces the need for manual handling of materials one by one during large-scale material loading, while also providing a loading area for small batches. This reduces the possibility of steel pipes falling during material lifting. Furthermore, the position of the lifting plate can be easily adjusted, improving the slope adjustment effect before the pipe is lowered. It also allows for pre-lubrication of the outer surface to reduce friction and improves the connection effect of the device. The connecting rod facilitates connection between the two, reducing jamming during steel pipe unloading. The solution is also convenient, simple, and more stable to operate.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Example: Refer to Figure 1-9A tube-feeding device for cold-drawing seamless stainless steel pipes includes a device frame plate 1, a lubrication mechanism 2, and a feeding rack 3. An adjusting plate 12 is rotatably connected to the device frame plate 1. A sliding tube 11 is mounted on the top surface of the adjusting plate 12, and the steel pipe is slidably connected to the top surface of the sliding tube 11. A support plate 17 is connected to the bottom surface of the adjusting plate 12. One end of the support plate 17 is connected to an angle adjusting mechanism, which includes an adjusting frame 14, a movable block 15, and an adjusting screw 16. An angle adjusting motor 18 is mounted on the outside of the angle adjusting mechanism, and the output end of the angle adjusting motor 18 is connected to the adjusting frame 14. One end of the screw rod 16 allows for easy control of the movement of the movable block 15. Two supports 13 are symmetrically mounted on one end of the top surface of the device frame plate 1. One side of the adjusting plate 12 is connected to the two supports 13 via a rotating shaft, facilitating the limited rotation of one end of the adjusting plate 12. An adjusting frame 14 is also fixed on the top surface of the device frame plate 1. The adjusting screw rod 16 is rotatably connected inside the adjusting frame 14, and the movable block 15 is threadedly connected to the outer side of the adjusting screw rod 16. Symmetrical through-type adjusting slots are provided on both sides of the adjusting frame 14. Adjusting rods are symmetrically mounted on both sides of the movable block 15, and the inner ends of the adjusting rods are welded. Installed on the movable block 15, the outer ends of the support plate 17 extend to the outer side of the adjustment groove. One end of the support plate 17 is rotatably connected to the bottom surface of the adjustment plate 12, and the other end is also rotatably connected to the outer tube of the adjustment rod. This allows the angle of the adjustment plate 12 to be adjusted within a certain range via the support plate 17 when the movable block 15 moves. Multiple sliding tubes 11 are fixedly installed on the adjustment plate 12. The lubrication mechanism 2 is installed on both sides of the adjustment plate 12. The lubrication mechanism 2 includes an upper frame plate 21, a bottom frame plate 24, a first lead screw, a drive motor 22, and a lubrication strip 23. The first lead screw is rotatably connected to the upper frame plate 21. Between the inner walls of 1, the lubricating strip 23 is movably connected to the outer surface of the first lead screw. The drive motor 22 is installed on the top surface of the upper frame plate 21. The feeding rack 3 is connected to one side of the device frame plate 1. A connecting rod 33 is rotatably connected to the feeding rack 3. A top frame 31 is installed on one side of the connecting rod 33. A lifting structure 6 is provided on the top frame 31. The lifting structure 6 includes a take-up roller 63, a pull rope 64, a lifting plate 65, an inner limit frame 67, and an outer limit frame 66. The pull rope 64 is connected between the lifting plate 65 and the take-up roller 63. The outer limit frame 66 is movably connected to the outside of the inner limit frame 67.

[0043] In this embodiment, a rotating rod 35 is rotatably connected inside the feeding rack 3. Multiple connecting rods 33 are fixedly installed, and the multiple connecting rods 33 correspond to the multiple slide tubes 11. One end of each connecting rod 33 is fixed to the rotating rod 35 for easy uniform adjustment of position. A positioning rod 38 is provided on the other end of the connecting rod 33 to position the connecting rod 33 and the slide tube 11. A second spring is connected between the positioning rod 38 and the connecting rod 33 to avoid contact during the connection process. A positioning piece 37 is also movably connected inside the connecting rod 33. A push block 36 is installed on the inner end of the positioning piece 37, and the outer end of the positioning piece 37 is connected to the outer side of the connecting rod 33 for easy connection to the slide tube 11. One end of each slide tube 11 is provided with a positioning hole and a positioning groove. The positioning piece 37 is movably connected in the positioning groove for positioning. One end of rod 38 is locked in the positioning hole. An adjustment plate 32 is installed on one end of rotating rod 35. The adjustment plate 32 is located outside the feeding rack 3. Push blocks 36 are symmetrically installed on the top surface of the feeding rack 3 to limit the material after it rises. The bottom end of the top frame 31 is also fixed on the top surface of the feeding rack 3 and is located outside the push block 36. Two take-up rollers 63 are symmetrically installed on the top surface of the top frame 31. A transmission rod 62 is connected between the take-up rollers 63. A lifting motor 61 is installed on the outside of one of the take-up rollers 63. The lifting motor 61, the two take-up rollers 63 and the transmission rod 62 rotate synchronously to achieve a balancing effect on both sides. Pull ropes 64 are connected to each take-up roller 63. The bottom ends of the two pull ropes 64 are connected to both ends of the lifting plate 65. The top surface of the lifting plate 65 is inclined. An embedded groove is provided on the back side of the feeding rack 3 to facilitate the movement of the outer limiting frame 66 on the feeding rack 3, thereby reducing the connection gap between the two. The inner limiting frame 67 is installed in the embedded groove, and a first limiting rod is installed in the inner limiting frame 67 to facilitate stability during movement. A first abutting block is welded and installed on the outer surface of the outer limiting frame 66. The abutting block is movably connected to the outer surface of the first limiting rod to keep it moving in a straight line. When the abutting block reaches the top of the inner limiting frame 67, the top surface of the outer limiting frame 66 will be flush with the top surface of the feeding rack 3. A second limiting rod is installed in the outer limiting frame 66 to stabilize the movement of the lifting plate 65. A second abutting block is installed on the rear side of the lifting plate 65. The second abutting block is connected to the outer surface of the second limiting rod. When the lifting plate 65 moves to the top of the outer limiting frame 66, the lifting plate 65 will be flush with the top surface of the outer limiting frame 66.

[0044] Working principle: When the quantity of material to be dropped is small, the steel pipe can be placed directly on the lifting plate 65. Because one end of the lifting plate 65 is higher, the steel pipe will roll to the other side after being placed. The other side is supported by the outer limit frame 66, preventing the steel pipe from falling during its ascent. When the equipment starts, the lifting motor 61 will begin to rotate, driving the take-up roller 63 on one side to rotate. Connected by the transmission rod 62, the take-up roller 63 on the other side will move synchronously. At this time, the pull rope 6... 4 will be continuously rolled upwards. During the rolling, the lifting plate 65 will be pulled upwards first. When it is pulled to the top of the outer limit frame 66, the outer limit frame 66 will move upwards in a straight line under the drag of the second abutment block. At this time, the position of the steel pipe will move to the top surface of the outer limit frame 66. Under the limit of the inner limit frame 67, it will not fall. When the first abutment block contacts the top of the inner limit frame 67, the outer limit frame 66 will be flush with the position of the feeding rack 3. At this time, the steel pipe will roll to the top surface of the feeding rack 3 under the influence of the slope.

[0045] When the lifting motor 61 starts, the position of the adjusting disc 32 is rotated. At this time, the rotating rod 35 will select the position of the connecting rod 33. When the position of the connecting rod 33 is aligned with the position of the slide tube 11, the positioning rod 38 will be connected inside the slide tube 11. Then, the push block 36 is pushed forward, and the positioning piece 37 will be connected inside the slide tube 11. At this time, the connecting rod 33 and the slide tube 11 will be fully connected. At this time, the steel pipe on the feeding rack 3 will start to drop materials, and then the dropped materials will be processed uniformly.

[0046] Example 2:

[0047] Reference Figure 10-17 Based on Embodiment 1, the following technical solutions are also provided:

[0048] A second lead screw 29 is fixedly installed on the bottom side plate 24. An outer sleeve rod 291 is rotatably connected to the outer side of the second lead screw 29. The top end of the outer sleeve rod 291 is rotatably connected to the bottom surface of the upper side plate 21. Both ends of the first lead screw extend to the outer side of the upper side plate 21, and a bevel gear set 27 is installed on both ends. The bevel gear set 27 includes vertical bevel teeth and horizontal bevel teeth. The vertical bevel teeth are welded to both ends of the first lead screw, and the horizontal bevel teeth mesh with the vertical bevel teeth. Support plates 28 are fixedly installed on both ends of the upper side plate 21. A short shaft is rotatably connected inside the support plate 28. The top end of the short shaft is fixed to the bottom surface of the horizontal bevel teeth, and an output roller is fixed to the bottom end of the short shaft. A transmission roller 26 is movably connected to the outer surface of the outer sleeve rod 291. The output roller and the transmission roller 26 are connected... A rotating belt 292 is provided. Through the connection of the rotating belt 292, the output roller rotates while simultaneously driving the transmission roller 26 to rotate synchronously. A drive motor 22 is installed at one end of the upper frame plate 21. The output end of the drive motor 22 is connected to the top surface of the horizontal bevel gear. The drive motor 22 acts as a power source, driving the first lead screw to rotate while also driving the outer sleeve rod 291 to rotate. The bottom end of the second lead screw 29 is fixed to the bottom frame plate 24, and the bottom end of the outer sleeve rod 291 is threaded to the top end of the second lead screw 29. The rotation of the outer sleeve rod 291 enables the lifting and lowering between the bottom frame plate 24 and the upper frame plate 21. An annular groove is provided on the outer surface of the outer sleeve rod 291. The transmission roller 26 is connected within the annular groove, serving as a limit and causing the transmission roller 26 to rotate. The current mechanism is more stable. Multiple slots 293 are provided on the bottom surface of the annular groove. A locking block 294 is movably connected to the bottom side of the transmission roller 26. A first spring connects the locking block 294 and the transmission roller 26 to facilitate the rapid rebound of the locking block 294 after it has been subjected to resistance. A first insert rod 295 is installed on the arc-shaped surface of the bottom side of the transmission roller 26. The first insert rod 295 is threadedly rotatably connected inside the transmission roller 26. The inner end of the first insert rod 295 is connected to the tail end of the locking block 294. The tail end of the locking block 294 is sloped, and the top end of the locking block 294 is engaged in the slot 293. At this time, a connection is formed between the transmission roller 26 and the outer sleeve rod 291, enabling synchronous rotation. Multiple bottom and upper frame plates 24 and 21 are provided, symmetrically installed on both sides of the adjusting plate 12. To facilitate the stable horizontal movement of the lubricating strip 23, both ends of the lubricating strip 23 are threaded to the outer surface of the first lead screw. Multiple contact blocks 25 are mounted on the bottom surface of the lubricating strip 23, with the contact blocks 25 corresponding to the positions of the slide tube 11. Each contact block 25 includes a housing 251, a ball bearing 252, and a wiping pad 253. The housing 251 is fixed to the bottom surface of the lubricating strip 23. The bottom surface of the housing 251 is divided into an arc-shaped convex surface and an arc-shaped concave surface to ensure complete contact between the wiping pad 253 and the slide tube 11. The ball bearing 252 is rotatably connected within the arc-shaped concave surface. The bottom side of the ball bearing 252 is connected to the slide tube 11, and lubricating oil is stored at the top of the ball bearing 252 to facilitate the application of lubricating oil to the surface of the slide tube 11 during the rolling process. An oil cavity is provided inside the housing 251.The lubricating oil is stored in the oil cavity. An oil filling port is provided on the top surface of the lubricating strip 23 for easy addition of lubricating oil. A wiping plate 253 is adhered to the arc-shaped convex surface and is connected to the outer surface of the slide tube 11 to facilitate the even wiping of the lubricating oil applied to the ball bearing 252.

[0049] Working principle: When the steel pipe falls and generates a lot of resistance or moves unevenly, the drive motor 22 is started. Driven by the drive motor 22, the bevel gear group 27 will start to rotate. When the bevel gear group 27 rotates, it will drive the first lead screw to rotate. At this time, the lubricating strip 23 will start to move at a constant speed. When the lubricating strip 23 moves, the ball 252 will roll on the slide tube 11. During the rolling process, the internal lubricating oil will be carried to the slide tube 11 and then completely coated on the outer surface of the slide tube 11 by the wiper 253 on the rear side. While the bevel gear group 27 rotates, it will also drive the rotating belt 292 to rotate. Driven by the rotating belt 292, the transmission roller 26 will rotate on the outer sleeve rod 291.

[0050] After wiping is completed, the drive motor 22 is stopped, and the positions of the transmission roller 26 and the outer sleeve rod 291 are aligned. At this time, the first insert rod 295 is rotated inward. The locking block 294 will move downward after being squeezed by the first insert rod 295 and then connect to the slot 293. At this time, the drive motor 22 is reversed. During the reverse rotation, due to the connection of the outer sleeve rod 291 and the transmission roller 26, the transmission roller 26 will rotate on the second lead screw 29 under the drive of the rotating belt 292. The transmission roller 26 will start to rise, and at the same time, the first lead screw will flip to return to its original position. After the rise, the position of the lubricating strip 23 will not obstruct the falling of the steel pipe.

The bottom end of the feeding rack 3 is connected to the top end of the base frame 52. Multiple through holes are symmetrically opened on the top end of the base frame 52. A second insert rod 34 is movably connected to the feeding rack 3. The second insert rod 34 is inserted into the through hole to facilitate the adjustment and fixation of the position of the feeding rack 3. A dispersing mechanism 4 is fixedly installed on one side of the base frame 52. The dispersing mechanism 4 includes a base 41, a fixing rod 42, a dispersing frame 43, a rotating roller 45, and a fixing bar 46. The base 41 is fixed to one side of the base frame 52. The top surface of the base 41 is inclined to facilitate the rolling of materials. Multiple fixing rods 42 are arranged and installed on the outside of the base 41 to place individual steel pipes. The fixing bar 46 is welded and installed on the inside of the base 41 to facilitate the storage of the lifting plate 65. The dispersing frame 43 is mounted on the outside of the base 41.

[0054] Working principle: When the slope of the adjusting plate 12 needs to be changed, the angle adjusting motor 18 is controlled to rotate, which drives the adjusting screw 16 to rotate. The movable block 15 will move, thereby adjusting the angle of the adjusting plate 12. At this time, the base frame 52 is adjusted to match the position. After adjustment, the loosening screw 51 is tightened to fix the position. The material feeding rack 3 is raised and lowered according to the angle of the adjusting plate 12. After moving to the appropriate height, the height is fixed by the second insert rod 34.

[0055] When a large amount of material is dropped, the material is placed in the arc-shaped placement opening 44. At this time, the dispersing motor 47 is controlled to rotate, which will drive the rotating roller 45 to rotate. The arc-shaped placement opening 44 will drop the material into the rotating roller 45 one by one. The rotating roller 45 will then rotate the material one by one and drop it onto the base 41. The lifting plate 65 is placed on the fixing bar 46. With the slope of the base 41, the material will fall directly onto the lifting plate 65. If there are materials with different diameters, they can be placed on the fixing rod 42 separately and then they will also move onto the lifting plate 65.
