Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to an inner diameter rounding machine. Background Technology
[0002] Steel pipes are classified according to their cross-sectional shape into round, square, rectangular, and special-shaped steel pipes; according to their material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; according to their application into pipes for transportation, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and according to their production process into seamless steel pipes and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, while welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.
[0003] High-pressure pipelines are connected by welding. To ensure weld quality, the two ends of the steel pipes to be welded are pre-rounded, making the pipe end alignment during welding more precise and convenient. For example, Chinese Patent Publication No. CN213671197U discloses "a steel pipe end rounding device", which has a rolling system on the inner and outer walls of the steel pipe and performs rolling rounding simultaneously. This can effectively prevent longitudinal creases from appearing on the pipe end surface during the rounding process. The device has high working efficiency and is suitable for mass-produced welded steel pipes. The ovality of the pipe end after being shaped by this device is ≤0.3%, and the shape is round and beautiful, which facilitates the alignment during welding and can effectively reduce weld defects after welding.
[0004] However, in actual use, since the inner and outer diameters of steel pipes of different specifications are different, and the thickness of the steel pipes is also different, the existing rounding device is difficult to round steel pipes of different specifications. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing rounding devices, such as difficulty in rounding steel pipes of different specifications, and to propose an inner diameter rounding machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design an inner diameter rounding machine, including a support base and a rotating disk. A motor connected to the rotating disk is installed on one side of the support base. A rounding module is installed on the rotating disk. A sliding groove is opened on the rotating disk. A slider that cooperates with the sliding groove is fixed on the rounding module. An adjustment mechanism that cooperates with the slider is provided on the rotating disk. A control component that cooperates with the adjustment mechanism is rotatably arranged on the rotating disk.
[0008] Furthermore, the adjustment mechanism includes a drive ring rotatably mounted on the rotating disk, and the drive ring is provided with a planar thread that is threadedly connected to the slider.
[0009] Furthermore, the drive ring is a bevel gear ring, the control component is a corresponding bevel gear, and the control component has polygonal slots.
[0010] Furthermore, the rounding module includes an inner rounding roller and an outer rounding roller, the slider is provided with a guide groove, and the slider is provided with a control structure that cooperates with the outer rounding roller.
[0011] Furthermore, the control structure includes a guide block slidably disposed within the guide groove, an outer circular roller connected to the guide block, and a screw threadedly connected to the guide block rotatably disposed on the slider.
[0012] Furthermore, an insert plate is fixedly provided on the guide block, and a slot corresponding to the insert plate is opened on the rotating shaft of the outer round roller. A bolt that is threadedly connected to the insert plate is provided on the rotating shaft of the outer round roller.
[0013] The beneficial effects of the inner diameter rounding machine proposed in this utility model are as follows:
[0014] In this utility model, by setting an adjustment mechanism and control components to cooperate, the positions of the slider and the rounding module are adjusted, thereby rounding steel pipes of different specifications.
[0015] Secondly, in this utility model, the position of the outer rounding roller is adjusted by setting a control structure, thereby changing the distance between it and the inner rounding roller, adapting to steel pipes of different thicknesses and improving the applicability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 An inner diameter rounding machine includes a support base 1 and a rotating disk 2. A motor connected to the rotating disk 2 is installed on one side of the support base 1. A rounding module 3 is installed on the rotating disk 2. A groove 4 is opened on the rotating disk 2. A slider 5 that cooperates with the groove 4 is fixed on the rounding module 3. An adjustment mechanism 6 that cooperates with the slider 5 is provided on the rotating disk 2. A control component 7 that cooperates with the adjustment mechanism 6 is rotatably arranged on the rotating disk 2.
[0023] In this utility model, the rounding module 3 is inserted into the steel pipe to be rounded, and the rotating disk 2 driven by the motor rotates to drive the rounding module 3 to rotate, thereby performing the rounding operation on the steel pipe. By setting the adjustment mechanism 6 and the control component 7 to cooperate, the position of the slider 5 and the rounding module 3 are adjusted, thereby rounding steel pipes of different specifications.
[0024] Furthermore, in this embodiment, the adjustment mechanism 6 includes a drive ring 61 rotatably disposed on the rotating disk 2. The drive ring 61 is provided with a planar thread 62 that is threadedly connected to the slider 5. When the drive ring 61 rotates, the planar thread 62 rotates accordingly and drives the slider 5 to move, changing the position of the slider 5 and the circular module 3.
[0025] Furthermore, in this embodiment, the drive ring 61 is a bevel gear ring, and the control component 7 is a corresponding bevel gear. The control component 7 has a polygonal slot 71. Preferably, there are three control components 7, which are in the form of an isosceles triangle and are all meshed with the drive ring 61. The slot 71 is used to connect a wrench to control the rotation of the drive ring 61 to adjust the position of the slider 5 and the round module 3.
[0026] It should be noted that in this embodiment, the rounding module 3 includes an inner rounding roller 31 and an outer rounding roller 32. The slider 5 is provided with a guide groove and a control structure 8 that cooperates with the outer rounding roller 32. The position of the outer rounding roller 32 is adjusted by the control structure 8, thereby changing the distance between it and the inner rounding roller 31 to adapt to steel pipes of different thicknesses and improve the applicability. Both the inner rounding roller 31 and the outer rounding roller 32 are rotatably provided with a rotating shaft, which is connected to the slider 5 or the control structure 8 through the rotating shaft.
[0027] Furthermore, in this embodiment, the control structure 8 includes a guide block 81 slidably disposed in the guide groove, an outer round roller 32 connected to the guide block 81, and a screw 82 rotatably disposed on the slider 5 and threadedly connected to the guide block 81. One end of the screw 82 is fixedly connected to a handwheel. By rotating the screw 82, the guide block 81 and the outer round roller 32 are moved, and the position of the outer round roller 32 is changed to adapt to steel pipes of different thicknesses.
[0028] More specifically, in this embodiment, a plate 83 is fixedly installed on the guide block 81, and a slot corresponding to the plate 83 is opened on the rotating shaft of the outer rounding roller 32. A bolt 84 threadedly connected to the plate 83 is provided on the rotating shaft of the outer rounding roller 32. The outer rounding roller 32 can be removed and replaced by rotating and removing the bolt 84. The inner rounding roller 31 is connected to the slider 5 in the same way.
[0029] Working method: During operation, the rounding module 3 is inserted into the steel pipe to be rounded. The rotating disk 2 driven by the motor rotates, which in turn drives the rounding module 3 to rotate, thereby performing the rounding operation on the steel pipe. The rotating control component 7 drives the drive ring 61 to rotate, and the flat thread 62 rotates accordingly, driving the slider 5 to move. The position of the slider 5 and the rounding module 3 is changed to adapt to steel pipes of different specifications. The rotating screw 82 drives the guide block 81 and the outer rounding roller 32 to move, changing the position of the outer rounding roller 32 to adapt to steel pipes of different thicknesses.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
