Detailed Implementation

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1-3The spatial tube bending fixture shown includes: a base 1, a fixture disc 2, and a bending mechanism 7. The fixture disc 2 is mounted on the base 1 and has multiple fixture ring grooves. Bearings are installed at the top and bottom of the fixture disc 2. The inner ring of the bearing is connected to the fixture disc 2, and the outer ring of the bearing is connected to an outer ring 12. The bending mechanism 7 includes a mounting frame 3 and a bracket. The bracket is mounted on the mounting frame 3 and is connected to the outer ring 12. The bending mechanism 7 also includes a main shaft 701 and a ring washer 15. 1. The main shaft 701 is longitudinally arranged with multiple sets of gradient plates on the mounting frame 3. The gradient plates are provided with pressure rollers corresponding to the jig ring groove. The mounting frame 3 is provided with insertion holes. The top gradient plate is provided with slots 10 corresponding to the insertion holes. The ring pad 15 is provided with pins 9 corresponding to the insertion holes. The pins 9 are connected to the insertion holes and slots 10. The jig also includes a slot seat 14, which is provided on the base 1. The slot seat 14 is provided with slots corresponding to the jig ring groove.

[0028] The aforementioned spatial pipe bending fixture utilizes multiple fixture annular grooves on the slot seat 14 and fixture disc 2 to hold pipes. These grooves can accommodate pipes of different sizes and models. The pressure roller on the mounting frame 3 moves along the fixture annular grooves to complete the pipe bending operation. The pin 9 engages with the insertion hole and slot 10 to limit and fix the spindle 701 during the bending process. Bearings allow the mounting frame 3 to rotate along the fixture disc 2 while the bent pipe remains stationary. The fixture can bend the pipe up to 180 degrees around the fixture disc 2. Afterward, the bent pipe can be directly removed from the fixture annular groove. The fixture is simple and easy to use, which helps improve work efficiency. Different slots on the slot seat 14 also guide the bent pipe, facilitating the pipe bending operation.

[0029] like Figures 1-3 As shown, in this embodiment, the fixture also includes a push rod 13, which is mounted on the mounting frame 3. The push rod 13 is fixedly mounted on the mounting frame 3. When the mounting frame 3 is pushed to move along the fixture annular groove to complete the pipe bending work, the use of the push rod 13 can save more effort and is more convenient, making it easier for workers to complete the pipe bending operation.

[0030] like Figures 1-3 As shown, in this embodiment, the fixture also includes a threaded sleeve 8, which is disposed on the ring pad 15. The main shaft 701 has an external thread 11, and the threaded sleeve 8 is connected to the external thread 11. The connection between the threaded sleeve 8 and the external thread 11 on the main shaft 701 limits and fixes the position of the ring pad 15, preventing the ring pad 15 from moving upward and causing the pin 9 to fail to limit the position. The threaded connection is very reliable. At the same time, the detachable connection of the threaded connection also helps the workers to remove the ring pad 15 and the pin 9, and further rotate and adjust the gradient plate and pressure roller to achieve the purpose of selecting different pressure rollers according to different pipe sizes.

[0031] like Figures 1-3 As shown, in this embodiment, the jig annular groove includes a first jig annular groove 4, a second jig annular groove 5, and a third jig annular groove 6. The first jig annular groove 4, the second jig annular groove 5, and the third jig annular groove 6 are arranged sequentially from the outside to the inside along the side wall of the jig disc 2. The dimensions of the first jig annular groove 4, the second jig annular groove 5, and the third jig annular groove 6 are different. In actual application, the first jig annular groove 4, the second jig annular groove 5, and the third jig annular groove 6 of different sizes can be designed according to the actual situation. The three annular grooves are designed on the same jig disc 2, which increases the integration and functionality of the jig and enables the bending of different pipes through one jig.

[0032] like Figures 1-3 As shown, in this embodiment, the gradient plate includes a first gradient plate 702, a second gradient plate 704, and a third gradient plate 706, all of which are arranged in pairs. The first gradient plate 702, the second gradient plate 704, and the third gradient plate 706 are evenly distributed on the main shaft 701. Each gradient plate is used to install each pressure roller. The first gradient plate 702, the second gradient plate 704, and the third gradient plate 706 are all fixedly installed on the main shaft 701. The purpose of the even distribution is to make the force of each pressure roller more evenly distributed during the working process and avoid stress concentration.

[0033] like Figures 1-3 As shown, in this embodiment, the pressure roller includes a first pressure roller 703, which is disposed on a first gradient plate 702 and corresponds to a first jig annular groove 4; the pressure roller also includes a second pressure roller 705, which is disposed on a second gradient plate 704 and corresponds to a second jig annular groove 5; the pressure roller also includes a third pressure roller 707, which is disposed on a third gradient plate 706 and corresponds to a third jig annular groove 6; each pressure roller and its corresponding jig annular groove have the same size, and can fit tightly with the pipe being bent, thereby achieving a good pipe bending effect.

[0034] like Figures 1-3 As shown, in this embodiment, the mounting frame 3 has multiple insertion holes, which are evenly distributed on the mounting frame 3. The multiple insertion holes can increase the limiting effect of the ring washer 15 and the pin 9, and prevent the spindle 701 from rotating during the bending process, thereby affecting the bending effect.

[0035] like Figures 1-3As shown in this embodiment, firstly, select the corresponding pressure roller according to the model and size of the pipe to be bent, loosen the threaded sleeve 8, remove the ring washer 15 and the pin 9, adjust the extended corresponding pressure roller to cooperate with the jig ring groove, then install the ring washer 15 and the pin 9, tighten the threaded sleeve 8 to complete the limit, and then put the pipe into the slot of the slot seat 14, with the pipe in contact with the pressure roller and the jig ring groove. Push the mounting frame 3 to drive the pressure roller to move along the jig ring groove to complete the pipe bending work. Since the jig can bend the pipe up to 180 degrees around the jig disc 2, the bent pipe can be directly removed from the jig ring groove after bending.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
