Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a rotary edge pressing machine. Background Art

[0002] During the processing of pipe fittings, in order to facilitate the connection between pipe fittings, the joints of the pipe fittings are usually flared. Now the commonly used pipe fittings are mostly copper pipes. After the flaring treatment, the pipe wall will become thinner, which will cause the strength of the joints to decrease. In order to increase the strength of the joints, the joints are usually folded to increase the thickness of the pipe wall, thereby increasing the strength of the joints.

[0003] As disclosed in authorization announcement No. CN218252543U, a pipe flaring and flanging structure includes a guide expansion head, a raised inclined surface, a flanging expansion head and a compression reset mechanism. The guide expansion head is used to guide the target pipe, the raised inclined surface is arranged on the guide expansion head, and the diameter of the raised inclined surface is larger than the diameter of the guide expansion head. A flanging end face is provided on the flanging expansion head, and the diameter of the flanging end face is larger than the raised inclined surface. The compression reset mechanism is used to cause relative sliding between the flanging expansion head and the guide expansion head, which can greatly improve the flanging quality of the target pipe, and thus improve the flanging effect of the target pipe.

[0004] In the above scheme, the inclined surface of the expansion head has a certain range. When the diameters of the pipes to be processed vary greatly, the above equipment cannot meet the requirements and has low applicability. The expansion head needs to be replaced during processing, resulting in low overall work efficiency. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-4The bottom of the base plate 1 is provided with a plurality of rollers 81, the bottom of the base plate 1 is slidably connected to the guide rail 8 by the rollers 81, and the guide rail 8 is fixed to the ground. A moving structure for driving the base plate 1 forward and backward is provided at the bottom of the base plate 1. The moving structure is used to adjust the distance between the base plate 1 and the end of the steel pipe and can realize the function of fixing the base plate 1. A support frame 2 is provided on the top of the base plate 1. A controller 7 for controlling the operation of each component is fixed on the support frame 2. Guide grooves 3 parallel to each other are vertically provided on the upper side of the support frame 2. The two ends of the lifting plate 4 are slidably connected with the corresponding guide grooves 3. A lifting structure for driving the lifting plate 4 to move up and down is provided on the top of the support frame 2. Because it is necessary to produce steel pipes of different diameters, the lifting structure is used to adjust the center height to ensure that it is consistent with the center height of the steel pipe. The side of the lifting plate 4 is rotatably connected to a driven gear disc 42. The lifting plate 4 is also provided with a driving structure that drives the driven gear disc 42 to rotate. The side of the driven gear disc 42 is fixed with a rotating plate 5. The pipeline is horizontally fixed near the rotating plate On one side of the plate 5 (not shown in the figure), the two ends of the rotating plate 5 are symmetrically connected with slide plates 52 in sliding cooperation. The rotating plate 5 is provided with a tank belt 53 for driving the slide plate 52 to move. There are two tank belts 53, which are symmetrically arranged. Starting the tank belt 53 is used to adjust the distance between the two slide plates 52. The two slide plates 52 are symmetrically provided with a pressing structure. By adjusting the distance between the two slide plates 52, steel pipes of different diameters can be expanded and pressed. The pressing structure includes a flaring column 54 and a flanging column 55. The mouth column 54 is vertically rotated and connected to the corresponding slide plate 52. The flaring column 54 is used to extend into the end of the pipe mouth. When the rotating plate 5 rotates, it drives the two flaring columns 54 to rotate in accordance with the inner wall of the pipe mouth to flare. A mounting bracket 56 is provided on the slide plate 52. The flanging column 55 is tilted and rotated to be connected to the mounting bracket 56 and cooperates with the flaring column 54. The flanging column 55 flanging the pipe mouth is fixed to the mounting bracket 56 by a fixing assembly 57. The central axis of the driven gear disc 42 coincides with the symmetrical center line of the two slide plates 52.

[0024] In some specific embodiments, such as Figure 2 As shown, in order to facilitate driving the entire device towards or away from the pipe mouth, the mobile structure includes a telescopic cylinder 82 and a fixed block 83. The end of the bottom of the base plate 1 close to the rotating plate 5 is hingedly connected to the driving end of the telescopic cylinder 82, and the fixed block 83 is fixedly set on the ground. The other end of the telescopic cylinder 82 is hingedly connected to the top of the fixed block 83. Extending the telescopic cylinder 82 can drive the base plate 1 to move toward the pipe mouth. When it moves to a suitable position, the entire device can be fixed.

[0025] In some specific embodiments, such as Figure 3As shown, in order to facilitate the adjustment of the center height of the edge pressing structure and ensure consistency with the center height of the steel pipe, the lifting structure includes a pull rod 6 and a drive assembly 63. A top plate 61 is provided on the top of the support frame 2, and the drive assembly 63 is provided on the top of the top plate 61. The drive assembly 63 is a motor, and a lifting assembly 62 is provided at the output end of the drive assembly 63, wherein the lifting assembly 62 can be a gear. One end of the pull rod 6 is hingedly connected to the lifting plate 4, and the other end passes through the top plate 61 and the end is matched with the lifting assembly 62. A gear rod matching the lifting assembly 62 is provided at the upper end of the pull rod 6. The rotation of the gear drives the pull rod 6 with the gear rod to move up and down, and the lifting assembly 62 is driven to rotate by starting the drive assembly 63 to lift or lower the height of the driven gear disc 42, so that the center height of the edge pressing structure of the driven gear disc 42 is consistent with the center height of the steel pipe.

[0026] In some specific embodiments, such as Figure 3 or Figure 4 As shown, in order to facilitate driving the driven gear plate 42 to drive the rotating plate 5 to rotate, the driving structure includes a driving gear 43, the driving gear 43 is rotatably connected to the lifting plate 4, and is meshed with the driven gear plate 42. The lifting plate 4 is also fixed with a motor 44 that drives the driving gear 43 to rotate. When the motor 44 is started, the driving gear 43 is rotated, and the driven gear plate 42 meshed with it also drives the rotating plate 5 to rotate.

[0027] In some specific embodiments, such as Figure 1 As shown, in order to enhance the smoothness of the movement of the lifting plate 4, a number of straight wheels 41 are distributed on both sides of the lifting plate 4. The straight wheels 41 are rollingly connected in the corresponding guide grooves 3. The lifting plate 4 is rollingly connected to the two guide grooves 3 through the straight wheels 41 to reduce the sliding friction of the contact surface.

[0028] In some specific embodiments, in order to facilitate the stable sliding of the slide plate 52 on the rotating plate 5, the rotating plate 5 is horizontally provided with several guide rods 51 parallel to each other, and the slide plate 52 is provided with a sliding groove that cooperates with the guide rods 51, and the slide plate 52 is slidably connected to the guide rods 51 through the sliding groove.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0030] The cam 52 is rotated to move along the guide rail 51 so that the two flaring columns 54 can be adjusted to move away from each other, thereby adapting to pipes of different diameters and sizes. This avoids the use of expansion heads in the prior art, which cannot expand and flange pipes with large diameter differences. The telescopic cylinder 82 is then started to push the entire device toward the pipe orifice, so that the flaring columns 54 fit the inner wall of the pipe orifice. Finally, the motor 44 is started to drive the driving gear 43 to rotate, and the driven gear 42 engaged therewith drives the rotating plate 5 to rotate, so that the two flaring columns 54 rotate along the inner wall of the pipe for flaring, and the two flanging columns 55 rotate against the ends of the pipe for flanging, which has strong applicability.

[0031] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
