[0002] Grooved pipe fittings are widely used metal connecting components in fluid transport systems, primarily for achieving quick connections, turns, or branches in pipelines. They achieve a sealed connection by machining annular grooves at the ends of the fittings, and then using clamps and other connectors. They offer advantages such as convenient installation, excellent sealing performance, and strong pressure resistance, and occupy an important position in building water supply and drainage, fire protection systems, and industrial pipelines. As a core component of pipeline connection systems, the molding quality of grooved pipe fittings directly affects the stability and safety of the entire system.

[0003] Utility model patent CN217964392U discloses a stamping die device for forming grooved pipe fittings, including an upper punch, a lower die, an adjusting frame, and a pressure roller structure, which can effectively stamp and form metal pipe fittings. However, in practical applications, this equipment still has significant technical defects.

[0004] Specifically, existing forming equipment cannot simultaneously assist metal pipes in rotating during the grooving process, which makes the pipes prone to rotational sluggishness or even jamming when grooving under pressure, seriously affecting the uniformity and consistency of grooving. Due to the lack of effective rotation drive or auxiliary guide structure, metal pipes are prone to displacement or deformation during processing, further affecting processing accuracy and yield.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a grooved pipe fitting forming equipment to solve this problem. This new equipment should be able to simultaneously rotate and assist the metal pipe fittings during stamping and forming, significantly improving the stability and consistency of groove processing, optimizing operational convenience and automation, better meeting the needs of high-precision, high-volume, and diversified production, and providing strong support for the high-quality development of the grooved pipe fitting manufacturing industry. Summary of the Invention

[0006] The purpose of this invention is to provide a grooved pipe forming equipment, which solves the problem that in the prior art, the forming equipment cannot simultaneously assist the metal pipe in rotating during the groove processing, which leads to the pipe easily experiencing rotational sluggishness or even jamming when under pressure for grooving, seriously affecting the uniformity and consistency of groove forming. Due to the lack of an effective rotation drive or auxiliary guide structure, the metal pipe is prone to displacement or deformation during processing, further affecting processing accuracy and yield.

[0007] To achieve the above objectives, this utility model provides a grooved pipe fitting forming equipment, including a base and a mounting frame connected to one side of the top of the base. A mounting seat is provided on one side of the mounting frame, and the top of the mounting seat is connected to the end of the mounting frame through a vertical lifting module. An upper pressure roller is rotatably connected inside the mounting seat. A drive motor is installed on the other side of the mounting frame, and the output shaft of the drive motor slides through the mounting frame and is connected to a tapered positioning column.

[0008] A movable ring is provided on the top of the base and on the side away from the mounting bracket.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example 1

[0023] Please see Figure 1-5 As shown, a grooved pipe forming device of this embodiment includes a base 1 and a mounting frame 5 connected to one side of the top of the base 1. A mounting seat 4 is provided on one side of the mounting frame 5. The top of the mounting seat 4 is connected to the end of the mounting frame 5 through a vertical lifting module. An upper pressure wheel 19 is rotatably connected inside the mounting seat 4. A drive motor 20 is installed on the other side of the mounting frame 5. The output shaft of the drive motor 20 slides through the mounting frame 5 and is connected to a tapered positioning column 18.

[0024] A movable ring 2 is provided on the top of the base 1 and on the side away from the mounting bracket 5. The bottom of the movable ring 2 is connected to the top of the base 1 through a horizontal moving structure. The inner ring of the movable ring 2 is rotatably connected to a rotating inner ring 8. Several clamping plates 16 are provided inside the rotating inner ring 8. Several pushing structures are provided on the outer ring of one end of the rotating inner ring 8. The output end of the pushing structure is connected to the clamping plate 16. A positioning structure that is detachably connected to the movable ring 2 is provided on the outer ring of the other end of the rotating inner ring 8.

[0025] The workflow is as follows: The operator places the pipe fitting 3 to be processed inside the rotating inner ring 8 and clamps and fixes the pipe fitting with several clamping plates 16. The clamping plates 16 achieve synchronous displacement through a pushing structure, thereby adapting to the clamping requirements of pipe fittings 3 with different diameter specifications. The moving ring 2 can slide and adjust its position on the base 1 in the horizontal direction through a horizontal moving structure to adapt to pipe fittings of different lengths or processing positions. A positioning structure is provided between the rotating inner ring 8 and the moving ring 2 to lock the position of the rotating inner ring 8 during processing to ensure processing stability. The drive motor 20 is started, and its output shaft drives the conical positioning column 18 to rotate and cooperate with the end of the metal pipe fitting for positioning. At the same time, the mounting base 4 drives the upper pressure roller 19 to move downward through the vertical lifting module, so that it presses the surface of the metal pipe fitting. As the drive motor 20 continues to run, the metal pipe fitting achieves stable rotation under the combined action of the upper pressure roller 19 and the conical positioning column 18. During the rotation, the continuous forming operation of the groove is completed. The setting of the mounting frame 5 and the vertical lifting module ensures the pressure uniformity and guiding accuracy during the stamping process, thereby improving the consistency and quality of groove forming. Example 2

[0026] Please see Figure 1-5As shown, this embodiment of a grooved pipe forming device includes a clamping cylinder 14 connected to the end edge of a rotating inner ring 8 via a support base 15. The output end of the clamping cylinder 14 is connected to an adjacent clamping plate 16. Specifically, through the cooperative arrangement of the clamping cylinder 14, the support base 15, and the clamping plate 16, after the metal pipe is placed inside the rotating inner ring 8, the clamping cylinder 14 is fixed to the end edge of the rotating inner ring 8 via the support base 15 and pushes the clamping plate 16 inward to achieve the clamping operation of the pipe. This structural design makes the clamping process more automated and precise, improves clamping efficiency and stability, and can adaptively adjust according to pipes of different diameters to avoid deviation or loosening during clamping.

[0027] The clamping plate 16 is made of metal, and a rubber pad is fixedly connected to its bottom. Specifically, the clamping plate 16 and the rubber pad are designed to work together. The clamping plate 16 is made of metal to ensure structural strength, and the rubber pad at its bottom allows for direct contact with the surface of the metal pipe. This structure ensures a firm clamping grip while effectively reducing wear and damage to the pipe surface during clamping, improving the finished product protection rate, and further guaranteeing the quality of groove forming. Example 3

[0028] Please see Figure 1-5 As shown, this embodiment of a grooved pipe forming device includes a horizontally moving structure comprising a support rod 10 and a moving block 11 slidably connected to the top of a base 1. One end of the base 1 is connected to a mounting plate 7, and a pushing cylinder 6 for cooperating with the moving block 11 is mounted on one side of the mounting plate 7. One end of the support rod 10 is connected to the bottom of the moving ring 2, and the other end is connected to the top of the moving block 11. Specifically, through the cooperative arrangement of the support rod 10, the moving block 11, the mounting plate 7, and the pushing cylinder 6, when the position of the moving ring 2 needs to be adjusted, the pushing cylinder 6 is activated and drives the moving block 11 to slide along the base 1, thereby causing the support rod 10 and the moving ring 2 connected to it to move horizontally as a whole. This structure enables the device to flexibly adapt to metal pipes of different lengths or processing positions, improving the device's versatility and ease of operation, while also enhancing the positioning accuracy during processing.

[0029] Several guide rods 17 connect the mounting plate 7 and the mounting frame 5. Both ends of the moving block 11 are slidably engaged with the guide rods 17. Specifically, through the cooperation of the guide rods 17, the mounting plate 7, and the moving block 11, the guide rods 17 connect the mounting plate 7 and the mounting frame 5, and the two ends of the moving block 11 are slidably engaged with the guide rods 17, providing guidance and support during the operation of the horizontally moving structure. This structure significantly improves the stability and straightness of the movement process, prevents processing errors caused by shaking, and enhances the stability and reliability of the equipment operation.

[0030] The positioning structure includes a positioning plate 13 fixedly connected to the end of the rotating inner ring 8 and a positioning screw 12 with one end threaded through the positioning plate 13. Several positioning holes 9, adapted to the positioning screw 12, are provided at one edge of the moving ring 2. Specifically, through the cooperation of the positioning plate 13, the positioning screw 12, and the positioning holes 9, after the rotating inner ring 8 is adjusted to a suitable angle or position, the operator can tighten the positioning screw 12, inserting its end into a set of positioning holes 9 on the moving ring 2, thereby locking the rotating inner ring 8 in the set position. This structural design improves the positioning accuracy and stability during processing, avoids affecting the consistency of groove forming due to the offset of the rotating inner ring 8, and enhances operational flexibility and the applicability of the equipment.

[0031] The overall structure of this equipment includes a base 1, a mounting frame 5, a mounting seat 4, a vertical lifting module, an upper pressure roller 19, a drive motor 20, a conical positioning column 18, a moving ring 2, a horizontal moving structure, a rotating inner ring 8, a clamping plate 16, a pushing structure, a positioning structure, and other main components. The complete workflow is as follows: The operator first places the metal pipe to be processed inside the rotating inner ring 8, and clamps and fixes the pipe using several clamping plates 16. The pushing structure consists of a clamping cylinder 14 and a support base 15. The clamping cylinder 14 is fixed to the edge of the rotating inner ring 8 via the support base 15, and pushes the clamping plates 16 inward to move synchronously, achieving adaptive clamping of metal pipes of different diameters and avoiding offset or loosening during clamping. The bottom of the moving ring 2 is connected to the base 1 via a horizontal moving structure, which includes a support rod 10, a moving block 11, a mounting plate 7, and a pushing cylinder 6. When the position needs to be adjusted, the pushing cylinder 6 is activated, causing the moving block 11 to slide along the base 1, which in turn drives the moving ring 2 to move horizontally as a whole via the support rod 10, achieving flexible adaptation to different lengths or processing positions. To improve the stability and guiding accuracy of the movement process, a guide rod 17 is connected between the mounting plate 7 and the mounting frame 5, and the moving block 11... The inner ring 8 and the moving ring 2 are fitted together to ensure stable movement and high straightness. A positioning structure is provided between the inner ring 8 and the moving ring 2, consisting of a positioning plate 13, a positioning screw 12 and a positioning hole 9. After the inner ring 8 is adjusted to the appropriate position, the positioning screw 12 is tightened so that its end is inserted into the corresponding positioning hole 9, thereby locking the position of the inner ring 8 and preventing deviation during processing. After clamping and positioning are completed, the drive motor 20 is started. Its output shaft drives the tapered positioning column 18 to rotate and cooperate with the end of the metal tube for positioning. At the same time, the mounting base 4 drives the upper pressure roller 19 to move downward through the vertical lifting module, pressing the surface of the metal tube. As the drive motor 20 continues to run, the metal tube achieves stable rotation under the combined action of the upper pressure roller 19 and the tapered positioning column 18. During the rotation, the continuous forming operation of the groove is completed. Throughout the process, the mounting frame 5 and the vertical lifting module ensure the uniformity of the stamping pressure and the guiding accuracy, thereby improving the consistency and quality of the groove forming.

[0032] The beneficial effects of this equipment are as follows: The combination of the rotating inner ring 8 and the clamping plate 16 enables effective clamping and rotational assistance of metal pipe fittings, solving the problem of traditional equipment being unable to synchronously assist in the rotation of metal pipe fittings during groove processing, significantly improving the uniformity and consistency of groove forming; the coordinated design of the clamping cylinder 14 and the support base 15 makes the clamping process more automated and precise, improving clamping efficiency and stability; the addition of a rubber pad at the bottom of the clamping plate 16 effectively reduces wear on the pipe fitting surface during clamping, improving the finished product protection rate; the synergistic effect of the support rod 10, the moving block 11, the mounting plate 7, and the pushing cylinder 6 enhances the equipment's adaptability to different sizes and processing positions, improving versatility and ease of operation; the design of the guide rod 17 improves the stability and straightness during horizontal movement, reducing processing errors caused by shaking; the coordinated use of the positioning plate 13, the positioning screw 12, and the positioning hole 9 in the positioning structure improves the positioning accuracy and stability during processing, preventing the rotating inner ring 8 from shifting and affecting the forming quality.
