[0004] In related technologies, a motor is used in conjunction with a clamping block with a triangular groove to clamp pipes of different diameters. However, after changing the pipe diameter, it is not easy to adjust the equipment according to the pipe diameter, which has certain limitations. Utility Model Content

[0030] This invention, through the synergistic effect of the adjustment components, allows the device to adjust the positions of the straightening mechanism and the diameter expansion mechanism according to the diameter of the steel pipe, eliminating the need for frequent changes of fixtures or molds.

[0042] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] Currently, the technology uses a motor and a clamping block with a triangular groove to clamp pipes of different diameters. However, it is not easy to adjust the equipment according to the pipe diameter after the pipe diameter is changed, which has certain limitations.

[0045] like Figure 1-5 As shown, this utility model embodiment provides an integrated pipe expansion and straightening device, including: a straightening mechanism 1, installed on one side of a first frame 2, which is located on the top of a workbench 6; an expansion mechanism 3, installed on the top of the workbench 6; and an adjustment component 4, provided between the first frame 2 and the expansion mechanism 3, to facilitate adjustment of the device according to the pipe diameter. The adjustment component 4 includes: a hydraulic push rod 41, fixedly installed on the top of the workbench 6, and positioned between the first frame 2 and the expansion mechanism 3; and a clamping block 42, fixedly installed... The output end of the hydraulic push rod 41 is mounted; the dual-axis motor 43 is mounted on the top of the worktable 6 and is positioned between the two first-level frames 2; the lead screw 44 is fixedly mounted on the output end of the dual-axis motor 43, and the lead screw 44 is threadedly connected to the first-level frame 2, with the threads of the two lead screws 44 in opposite directions; the first plate 45 is fixedly connected to the top of the worktable 6, and one end of the lead screw 44 is rotatably connected to one side of the first plate 45; the conveying roller 47 is mounted on one side of the first-level frame 2 through the mounting mechanism 46 and is used to assist the straightening mechanism 1 in calibration.

[0046] In use, the operator first inserts the steel pipe to be straightened between the straightening mechanisms 1 on both sides. Multiple sets of inclined rollers that abut against the surface of the steel pipe press the deformed edges of the steel pipe. During the straightening process, the steel pipe is also conveyed by the rotation of the rollers, thereby eliminating most of the bending and deformation in the entire steel pipe. When the straightened steel pipe is conveyed to the expansion mechanism 3, the steel pipe is conveyed to the outside of the expansion head on one side of the expansion mechanism 3. Then, the hydraulic push rod 41 pushes the clamping block 42 to clamp the steel pipe to prevent the steel pipe from shifting during the expansion process and affecting the quality of the expansion. Then, the hydraulic cylinder inside the expansion mechanism 3 is activated to push the shaft to move horizontally. The shaft with a gradually increasing diameter will push up the surrounding separable expansion heads during the movement, thereby pushing the end of the steel pipe through the expansion heads to achieve the expansion of one end of the steel pipe (the rollers, hydraulic cylinders, and expansion heads are all existing technologies and are not shown in the figure, so they will not be described in detail here).

[0047] When straightening and expanding steel pipes of different diameters, the dual-axis motor 43 is first turned on, driving the lead screws 44 on both sides to rotate synchronously in the same direction. Since the threads of the two lead screws 44 are opposite, under the action of the threads of the lead screws 44 and the first frame 2, the first frame 2 on both sides moves in opposite directions. First, the first frame 2 on both sides is adjusted to contact the first plate 45. Then, the two hydraulic push rods 41 are started synchronously, and the two clamping blocks 42 are adjusted so that the distance between the centers of the two clamping blocks 42 is greater than the distance between the steel pipes. Then, the steel pipe to be processed is lifted between the two clamping blocks 42, and one end of the steel pipe is placed between the straightening mechanisms 1 on both sides. The two hydraulic push rods 41 are started synchronously to push the two clamping blocks 42 to clamp the steel pipe. After clamping, the dual-axis motor 43 is started to drive the first frame 2 on both sides to move closer to each other. Until the edge of the center of the conveyor roller 47 is in close contact with the edge of the steel pipe, the rudder disk on the straightening mechanism 1 is rotated to adjust the position of the inclined roller shaft, thereby adjusting the pressure of the inclined roller shaft on the steel pipe. At the same time, since the dual-shaft motor 43 has made an initial adjustment to the position of the straightening mechanism 1 when adjusting the first frame 2, and the edge of the center of the conveyor roller 47 is on the same horizontal line as the adjusted center edge of the roller shaft, when the conveyor roller 47 abuts against the steel pipe, the roller shaft in the straightening mechanism 1 is also in close contact with the surface of the steel pipe. This facilitates the subsequent adjustments of the straightening mechanism 1 by the operator, making it convenient and quick. (The roller shaft in the straightening mechanism 1 is existing technology. When dealing with steel pipes of different diameters, it is necessary to adjust the degree of contact between the roller shaft and the steel pipe through the rudder disk to ensure the straightening work is carried out. The rudder disk is connected to the mounting seat of the roller shaft through a threaded rod. Rotating the rudder disk can adjust the position of the roller shaft.)

[0048] Furthermore, the installation mechanism 46 includes: a second frame 461, which is fixedly installed on one side of the first frame 2; a motor 462, which is fixedly installed on the top of the second frame 461 and electrically connected to an external power source; one end of the conveying roller 47 is fixedly connected to the output end of the motor 462; and the other end of the conveying roller 47 is rotatably connected to the second frame 461.

[0049] The motor 462 facilitates the rotation of the conveyor roller 47. The motors 462 on both sides drive the conveyor roller 47 to rotate in opposite directions, thereby pushing the steel pipe towards the clamping block 42 under the clamping and rotation of the conveyor rollers 47 on both sides, which facilitates the subsequent diameter expansion.

[0050] Furthermore, a pre-adjustment component 5 is provided on one side of the first frame 2; the pre-adjustment component 5 includes: a column 51, which is fixedly connected to the top of the workbench 6, and the diameter of the column 51 is the same as the inner diameter of the steel pipe that the expansion mechanism 3 can expand to the minimum; a second plate 52, which is fixedly connected to one side of the first frame 2; and a third plate 54, which is inserted into one side of the second plate 52 by a plug 53, and the plug 53 is fastened to the second plate 52 by screws.

[0051] When adjusting steel pipes of different diameters between the conveyor rollers 47, the steel pipes can be inserted outside the column 51. If the inner diameter of the steel pipe is too small and cannot be inserted outside the column 51, the expanding head in the expanding mechanism 3 will also be unable to expand the diameter of the steel pipe. In this case, the equipment mold needs to be replaced or other equipment needs to be used. After inserting the steel pipe outside the column 51, start the dual-shaft motor 43 and drive the No. 1 frame 2 on both sides to move towards each other through the lead screw 44 until the edges of the two No. 3 plates 54 are just in contact with the surface of the steel pipe. At this time, it means that the steel pipe can just pass between the two conveyor rollers 47. Inserting the steel pipe between the two conveyor rollers 47 allows for fine adjustment of the straightening mechanism 1, saving time for subsequent adjustments.

[0052] Furthermore, the distance between the two No. 3 plates 54 is the same as the distance at the center edge of the two conveying rollers 47, so the position of the conveying rollers 47 can be adjusted without clamping the steel pipe between the two clamping blocks 42.

[0053] Furthermore, a groove 422 is provided on one side of the clamping block 42. The groove 422 is triangular and an anti-slip pad is provided inside the groove 422 to increase the clamping range of the clamping block 42 and enhance the clamping stability through the anti-slip pad.

[0054] Furthermore, a slide rail 21 is slidably connected to the bottom of the first frame 2, and one side of the slide rail 21 is fixedly connected to the first plate 45 to enhance the stability of the sliding of the first frame 2.

[0055] Furthermore, a base 411 is fixedly connected to the bottom of the hydraulic push rod 41, which facilitates raising the clamping block 42 so that the center of the clamping block 42 is at the same height as the diameter expansion mechanism. A second slide rail 421 is provided on the top of the base 411, and the clamping block 42 is slidably connected to the second slide rail 421 to enhance the stability of the sliding of the clamping block 42.

[0056] Furthermore, when the first frame 2 is adjusted to contact the first plate 45, the diameter of the steel pipe held by the clamping block 42 is exactly the same as the maximum clamping diameter of the clamping block 42. If the steel pipe still cannot be inserted into the outside of the column 51 when the first frame 2 is adjusted to contact the first plate 45 (it cannot be lowered because it is blocked by the third plate 54 on both sides), it means that the outer diameter of the steel pipe exceeds the clamping range of the clamping block 42, and it is necessary to replace the mold or use other equipment for processing.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
