Description

Technical Field

[0001] This utility model relates to the field of straightening devices, specifically to a titanium alloy tube straightening device. Background Technology

[0002] Titanium alloy pipes are pipes made using titanium alloys, a type of metal pipe with titanium as the main alloying element. They are manufactured using titanium alloy materials as the main raw material through processes such as extrusion, rolling, and welding to produce pipeline products used for transporting fluids, gases, and solids. Titanium alloy pipes are widely used in many fields due to their high strength, low density, good mechanical properties, and corrosion resistance. Steel pipe straightening refers to the process of restoring bent or twisted steel pipes to their original straight state through various methods and techniques. This process is crucial for ensuring the structural strength of the steel pipe and extending its service life.

[0003] A Chinese patent authorization announcement (CN221715337U) discloses a straightening device for large-diameter titanium alloy tubes. This utility model includes: a first square frame; a first straightening roller, both rotatably mounted within the first square frame; support columns, both fixedly mounted on the upper surface of the first square frame; a second square frame located above the first square frame; a second straightening roller, both rotatably mounted within the second square frame; and a driving mechanism disposed on the outer wall of the first square frame, used to drive the pair of first straightening rollers to rotate. Under the action of the driving mechanism, the first straightening roller, the titanium alloy tube, and the second straightening roller can rotate, allowing the first and second straightening rollers to straighten the titanium alloy tube from all directions, making the straightness of the titanium alloy tube more accurate. Simultaneously, the rolling motion of the first and second straightening rollers in straightening the titanium alloy tube also avoids damage to the surface of the titanium alloy tube, providing convenience.

[0004] The above-mentioned straightening device also has the following problems when in use: the gap between the two sets of straightening rollers is difficult to adjust when in use, which limits the size of the tube diameter that can be adapted to the straightening device, resulting in low applicability of the entire straightening device.

[0005] Therefore, it is necessary to invent a titanium alloy tube straightening device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a titanium alloy tube straightening device to solve the problem mentioned in the background art that the gap between the two sets of straightening rollers is difficult to adjust during use, which limits the tube diameter that can be adapted to the straightening device and results in low applicability of the entire straightening device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a titanium alloy pipe straightening device, comprising a fixed frame, with legs fixedly connected to the four bottom corners of the fixed frame, and a top plate fixedly connected to the four top corners of the fixed frame via uprights, and a cylinder fitted inside the top plate, with a connecting rod fixedly connected to the output end of the cylinder, and a movable frame fixedly connected to the lower end of the connecting rod, and rollers movably installed inside both the fixed frame and the movable frame via adjusting components.

[0008] Preferably, there are two sets of four rollers in total, and each of the fixed frame and the movable frame is rotatably connected to a set of two rollers. The outermost ring of the rollers protrudes from the height of the upper and lower end walls of the fixed frame and the movable frame, so that the tube to be processed can be matched with the middle position of the two rollers to achieve the straightening process of the tube.

[0009] Preferably, the adjustment components are provided in two sets, and the two sets of adjustment components are respectively connected to the fixed frame and the movable frame.

[0010] The adjustment component includes channels reserved inside the fixed frame and the movable frame, and square channels are provided at both the left and right ends of the fixed frame and the movable frame to facilitate subsequent adjustment operations of the adjustment component.

[0011] Preferably, the adjustment assembly further includes a motor fixedly connected to the side wall of the fixed frame and the movable frame, and the output shaft of the motor is driven by a drive shaft. The drive shaft is rotatably connected to a channel on one side, and a bevel gear set is externally connected to the drive shaft. The bevel gear set is driven by the inner ring roller shaft of the roller. After the drive shaft rotates, the rotation of the roller is adjusted through the bevel gear set.

[0012] Preferably, the bevel gear set consists of two meshing bevel gears, which are symmetrically arranged. One bevel gear set is connected to the drive shaft and the roller shaft of the inner ring of a roller, while the other bevel gear set is connected to the sleeve rod that is movably fitted on the outer ring of the drive shaft and the roller shaft of the inner ring of another roller. A connecting block is fixedly connected to the inner ring of the sleeve rod, and the outer wall of the connecting block is in contact with the inner wall of the pre-reserved movable groove inside the drive shaft to achieve a sliding connection. This ensures that the two rollers connected to the two bevel gear sets do not rotate in the same direction, which facilitates the subsequent processing of the tube body.

[0013] Preferably, a threaded rod is rotatably connected to the inner wall of another channel, and a block is threadedly connected to the outer ring of the threaded rod. The outer wall of the block is in contact with the inner wall of the channel to achieve a sliding connection. The other block is rotatably connected to the smooth outer wall of the threaded rod. The end of the inner ring roller shaft of the roller is rotatably connected to the block. The outer wall of the block is fixedly connected to the inner wall of the channel. The twisting threaded rod is used to adjust the distance between the two rollers.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The spacing between the two sets of rollers can be adjusted by adjusting the settings of the components. This allows the tube to be processed to be well matched with the position of the two rollers in one set. As a result, the rotation of the two sets of rollers can straighten the tube. The spacing between the two rollers in each set can be adjusted, which makes it easy for tubes with different outer diameters to match the position of the two rollers in one set. This increases the applicability of the straightening equipment. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The titanium alloy tube straightening device shown includes a fixed frame 1, with support legs 2 fixedly connected to the four corners of the bottom of the fixed frame 1, and a top plate 4 fixedly connected to the four corners of the top of the fixed frame 1 via uprights 3. A cylinder 5 is fitted inside the top plate 4, and a connecting rod 6 is fixedly connected to the output end of the cylinder 5. A movable frame 7 is fixedly connected to the lower end of the connecting rod 6. Rollers 8 are movably installed inside both the fixed frame 1 and the movable frame 7 via adjusting components 9.

[0025] During use, the distance between the two sets of rollers 8 can be adjusted by adjusting the setting of component 9. This allows the tube to be processed to be well aligned with the position of the two sets of rollers 8, so that the rotation of the two sets of rollers 8 can straighten the tube. The tube to be processed is placed between the two rollers 8 inside the fixed frame 1. Then, the cylinder 5 is activated, causing the movable frame 7 to descend. Inside the movable frame 7, the two sets of rollers 8 abut against the tube to be processed. Then, the motor 902 is activated, and the two sets of rollers 8 are rotated through the bevel gear set 907 to process the tube. The straightening process of the rollers 8 is the same as the straightening roller rotation process of the tube in the comparative patent, and will not be described again here.

[0026] There are two sets of rollers 8, totaling four. Each of the fixed frame 1 and the movable frame 7 is rotatably connected to a set of two rollers 8. The outermost ring of the rollers 8 protrudes beyond the height of the upper and lower end walls of the fixed frame 1 and the movable frame 7, so that the tube to be processed can be matched with the middle position of the two rollers 8 to achieve the straightening process of the tube.

[0027] To facilitate the use of the adjustment component 9, two sets of adjustment components 9 are provided. The two sets of adjustment components 9 are respectively connected to the fixed frame 1 and the movable frame 7 in a transmission manner. The adjustment component 9 includes a channel 901 reserved inside the fixed frame 1 and the movable frame 7, and square channels 901 are provided at both the left and right ends of the fixed frame 1 and the movable frame 7 to facilitate subsequent adjustment operations of the adjustment component 9.

[0028] The adjustment assembly 9 also includes a motor 902 fixedly connected to the side wall of the fixed frame 1 and the movable frame 7. The output shaft of the motor 902 is driven by a drive shaft 903. The drive shaft 903 is rotatably connected to a side channel 901. The drive shaft 903 is externally driven by a bevel gear set 907. The bevel gear set 907 is driven by the inner ring roller shaft of the roller 8.

[0029] The motor 902 drives the drive shaft 903 to rotate, and then the bevel gear set 907 adjusts the rotation of the roller 8. This makes the two rollers 8 rotate in different directions, and the tube body that is matched with the two rollers 8 will not slip off when the rollers 8 rotate.

[0030] The bevel gear set 907 consists of two meshing bevel gears. The two sets of bevel gear sets 907 are symmetrically arranged. One set of bevel gear sets 907 is connected to the drive shaft 903 and the roller shaft of the inner ring of a roller 8. The other set of bevel gear sets 907 is connected to the sleeve rod 904, which is movably fitted on the outer ring of the drive shaft 903, and the roller shaft of the inner ring of another roller 8. A connecting block 905 is fixedly connected to the inner ring of the sleeve rod 904. The outer wall of the connecting block 905 is in contact with the inner wall of the movable groove 906 reserved inside the drive shaft 903 to achieve a sliding connection. When a roller 8 is displaced, the bevel gear set 907 connected to the roller 8 moves synchronously on the outer ring of the drive shaft 903 to ensure that the rotation of the roller 8 is not affected.

[0031] Ensure that the two rollers 8, which are connected to the two sets of bevel gears 907, do not rotate in the same direction, so as to facilitate the subsequent processing of the tube body.

[0032] To facilitate the adjustment of the distance between the two rollers 8, a threaded rod 908 is rotatably connected to the inner wall of another channel 901, and a block 909 is threadedly connected to the outer ring of the threaded rod 908. The outer wall of the block 909 is in contact with the inner wall of the channel 901 to achieve a sliding connection, and the other block 909 is rotatably connected to the smooth outer wall of the threaded rod 908. The outer wall of the block 909 is fixedly connected to the inner wall of the channel 901, and the end of the inner ring roller shaft of the roller 8 is rotatably connected to the block 909.

[0033] The twisting of the threaded rod 908 causes the block 909, which is threadedly connected to the threaded rod 908, to shift inside the channel 901. This causes the position of the roller 8, which is rotatably connected to the block 909, to shift. One of the bevel gears in the bevel gear set 907, which is driven by the inner ring roller shaft of the roller 8, is fitted onto the outer ring of the sleeve rod 904. Thus, when the roller 8 shifts, the transmission effect of the bevel gear set 907 is impaired, and the rotation of the roller 8 is not affected.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
