Abstract
Description
Technical Field
[0001] This utility model belongs to the field of circular product shaping technology, specifically a circular shaping tool. Background Technology
[0002] Currently, the shaping of round products can be achieved using rolling mills. This involves mounting the product to be shaped on the rolling mill and reshaping or correcting it to achieve the desired shape. However, dedicated rolling mills are expensive, and multiple shaping and correction processes consume a significant amount of time. Furthermore, the deformation of the shaped product may not be maintained for an extended period. Local shaping methods, such as using internal push rods or conical pressing into the port to achieve local shaping of the inner diameter or port, are convenient to operate, but the internal push rods still require multiple adjustments and have lower precision. Therefore, they cannot meet the requirements for rapid and accurate rounding of existing shaped products.
[0003] Meanwhile, a circular shaping fixture with announcement number CN205380164U is disclosed, including an arc-shaped left support ring and a right support ring that are connected to each other in a circular ring shape. There is a gap between the end of the left support ring and the corresponding end of the right support ring. A support block is embedded in the gap. The support block has a trapezoidal structure. An adjustment device is provided between the two support blocks to adjust the distance between the two support blocks.
[0004] The aforementioned circular shaping fixture applies pressure to the part to make it round during use. However, it lacks a limiting structure, which can easily cause the part to shift and deform, increasing the degree of deformation. This not only consumes time and effort but also increases the cost of shaping. Furthermore, this design can only shape parts of one size, resulting in a limited range of applications.
[0005] Therefore, a circular shaping fixture is proposed to address the above problems. Utility Model Content
[0006] To address the problems mentioned in the background section, this utility model provides a circular shaping fixture, which has the advantages of more precise shaping and a wider range of applications.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a circular shaping fixture, including a chassis, a connecting column one fixedly disposed above the chassis, a connecting column two fixedly disposed above the connecting column one, a fixing column fixedly disposed on the outer side of the connecting column two, an electric telescopic rod fixedly disposed at the top of the fixing column, and a shaping ring one fixedly disposed at the top of the electric telescopic rod.
[0008] Preferably, a slide rail is fixedly provided on the top of the chassis, a slider is slidably provided inside the slide rail, a limiting ring is fixedly provided on the top of the slider, and a telescopic rod is fixedly provided on the right side of the limiting ring.
[0009] By adopting the above technical solution, a slide rail is set up, and a slider slides within the slide rail to make the limiting ring slide. During operation, it is easy to adjust according to the different diameters of the shaped parts, making it more convenient to use.
[0010] Preferably, a slide rail 2 is fixedly provided above the chassis, a slider 2 is slidably provided inside the slide rail 2, and a connecting column 3 is fixedly provided above the slider 2.
[0011] By adopting the above technical solution, slide rail two is set up so that slider two slides within slide rail two, thereby causing connecting column three to slide and adjust its position.
[0012] Preferably, a shaping ring two is fixedly provided above the connecting column three, a rubber pad is fixedly provided inside the shaping ring two, and a threaded hole is opened inside the shaping ring two.
[0013] By adopting the above technical solution, a rubber pad is set inside the second shaping ring to prevent excessive deformation of the parts due to excessive force during use, thus reducing processing costs.
[0014] Preferably, the inner spiral of the shaping ring two is provided with a threaded rod two, the left side of the threaded rod two is fixedly provided with a hydraulic telescopic rod two, the left side of the hydraulic telescopic rod two is fixedly provided with a connecting plate two, the left side of the connecting plate two is fixedly provided with a connecting plate one, the left side of the connecting plate one is fixedly provided with a hydraulic telescopic rod one, the left side of the hydraulic telescopic rod one is fixedly provided with a threaded rod one, and the threaded rod one is spirally arranged with the shaping ring two.
[0015] By adopting the above technical solution, the threaded rod 2 is extended and retracted by the extension and retraction of the hydraulic telescopic rod 2, and the threaded rod 1 is extended and retracted by the extension and retraction of the hydraulic telescopic rod 1, thereby adjusting the diameter of the shaping ring 2, making it applicable to parts of different sizes and thus having a wider range of applications.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model sets up a connecting column two and connects the electric telescopic rod with the fixed column. When the part is put on the device for shaping, the electric telescopic rod is activated to stretch the shaping ring one. By applying pressure to the part, the part is shaped. At the same time, the shaping ring two is designed on the outside for limiting. The two work together to make the shaping more convenient and faster, increase the success rate, and reduce the processing cost.
[0018] 2. This utility model features a slide rail, in which a slider slides to allow the limiting ring to slide. During operation, this allows for easy adjustment based on the diameter of the shaped part, making it more convenient to use. The extension and retraction of the hydraulic telescopic rod 2, and the extension and retraction of the hydraulic telescopic rod 1, further extend and retract the threaded rod 2, thereby adjusting the diameter of the shaped ring 2. This makes it suitable for parts of different sizes, thus broadening its applicability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The following describes an embodiment of this utility model based on its overall structure.
[0027] like Figures 1 to 5 As shown, this utility model provides a circular shaping fixture, including a chassis 1. A connecting column 8 is fixedly mounted on the top of the chassis 1, and a connecting column 9 is fixedly mounted on the top of the connecting column 8. A fixing column 22 is fixedly mounted on the outer side of the connecting column 29. An electric telescopic rod 7 is fixedly mounted on the top of the fixing column 22, and a shaping ring 6 is fixedly mounted on the top of the electric telescopic rod 7. The connecting column 29 is used to connect the electric telescopic rod 7 through the fixing column 22. When the part is placed on the device for shaping, the electric telescopic rod 7 is activated to stretch the shaping ring 6, thereby applying pressure to the part for shaping.
[0028] In this embodiment, a slide rail 4 is fixedly mounted on the top of the chassis 1. A slider 5 is slidably mounted inside the slide rail 4. A limiting ring 2 is fixedly mounted above the slider 5. A telescopic rod 3 is fixedly mounted on the right side of the limiting ring 2. The slide rail 4 allows the limiting ring 2 to slide by sliding the slider 5 within the slide rail 4. This facilitates adjustment according to the different diameters of the shaped parts during operation, making it more convenient to use. A slide rail 17 is fixedly mounted on the top of the chassis 1. A slider 16 is slidably mounted inside the slide rail 17. A connecting post 15 is fixedly mounted above the slider 16. The slide rail 17 allows the slider 16 to slide within the slide rail 17, thereby allowing the connecting post 15 to slide and adjust its position. A shaping ring 10 is fixedly mounted above the connecting post 15. A rubber pad 18 is fixedly mounted inside the shaping ring 10. A screw is opened inside the shaping ring 10. The forming ring 10 has a perforated hole 14. A rubber pad 18 is installed inside the forming ring 10 to prevent excessive deformation of the part due to excessive force during use, which would increase the processing cost. The forming ring 10 has a threaded rod 21 spirally installed inside. A hydraulic telescopic rod 19 is fixedly installed on the left side of the threaded rod 21. A connecting plate 20 is fixedly installed on the left side of the hydraulic telescopic rod 21. A connecting plate 13 is fixedly installed on the left side of the connecting plate 20. A hydraulic telescopic rod 12 is fixedly installed on the left side of the connecting plate 13. A threaded rod 11 is fixedly installed on the left side of the hydraulic telescopic rod 12. The threaded rod 11 is spirally connected to the forming ring 10. The threaded rod 19 is extended and retracted by the hydraulic telescopic rod 19, and the threaded rod 12 is extended and retracted by the hydraulic telescopic rod 11. This adjusts the diameter of the forming ring 10, making it suitable for parts of different sizes and thus more versatile.
[0029] The working principle and process of a circular shaping fixture:
[0030] A circular shaping fixture, in use, adjusts the position of the limiting ring 2 by extending and retracting the telescopic rod 3, while the slider 5 slides within the slide rail 4. The extension and retraction of the hydraulic telescopic rod 19 causes the threaded rod 21 to extend and retract, and the extension and retraction of the hydraulic telescopic rod 12 causes the threaded rod 11 to extend and retract, thereby adjusting the diameter of the shaping ring 10. Next, the part to be shaped is passed through the connecting post 8 and placed on the base 1, where it is limited by the limiting ring 2 and the shaping ring 10. Then, the electric telescopic rod 7 is activated, stretching the shaping ring 6. Pressure is applied to the part for shaping. A rubber pad 18 is placed inside the shaping ring 10 to prevent excessive deformation of the part due to excessive force during use. This design allows the shaping rings 6 and 10 to work together, making shaping more convenient and faster, increasing the success rate, and making it suitable for parts of different sizes, thus broadening its applicability.
