[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a frame crossbeam bending processing device, including a fixed platform 1 and a power turntable 5 disposed on one side of the fixed platform 1. The end of the power turntable 5 near the fixed platform 1 is rotatably connected to the fixed platform 1, and a tube pushing mechanism is provided on the upper end of the fixed platform 1. A reduction motor for controlling the rotation of the power turntable 5 is installed at the bottom of the fixed platform 1, which is used to control the power turntable 5 to rotate around the end connected to the fixed platform 1. This will not be described in detail here.

[0022] The upper end of the power turntable 5 is provided with a shaping frame A6 and a shaping frame B8. The shaping frame B8 is placed on one side of the shaping frame A6 and cooperates with the shaping frame A6. Multiple bent pipe grooves A12 are opened on the facing sides of the shaping frame A6 and the shaping frame B8. The lower end of the shaping frame A6 is fixedly connected to the power turntable 5. The upper end of the shaping frame A6 is provided with a secondary frame B11, which is detachably connected to the shaping frame A6.

[0023] The lower end of the shaping platform B8 is fixedly connected to the slide assembly A located on the upper end of the power turntable 5. The upper end of the shaping platform B8 is provided with a secondary platform A10, which is detachably connected to the shaping platform B8. The facing sides of the secondary platform A10 and the secondary platform B11 are provided with bent pipe grooves B13.

[0024] The crossbeams of the chassis pipes that need to be bent are placed on the upper end of the fixed platform 1. The pipe pushing mechanism pushes the crossbeams towards the power turntable 5. After being pushed between the shaping platform A6 and the shaping platform B8, the slide assembly A pushes the shaping platform B8 towards the shaping platform A6. After the shaping platform A6 and the shaping platform B8 are closed, the crossbeams are limited by the bending grooves A12 and B13. The reduction motor at the bottom of the fixed platform 1 controls the rotation of the power turntable 5. During the rotation, the power turntable 5 completes the bending of multiple sets of crossbeams through the auxiliary platform A10 and the auxiliary platform B11.

[0025] Sub-stands A10 and B11 are installed on the upper end of the standard stands A6 and B8. The detachable installation method makes it easy for staff to replace sub-stands A10 and B11 with different hole diameters. While retaining the original standard stands A6 and B8, they can be adapted to crossbeam pipes of different diameters, making them widely applicable.

[0026] Both the shaping stand A6 and the shaping stand B8 are provided with insert plates 16 at their upper ends. The two insert plates 16 are fixedly connected to the shaping stand A6 and the shaping stand B8 respectively. The auxiliary stands A10 and B11 are respectively sleeved on the outside of the two insert plates 16. The insert plates 16 are slidably connected to the auxiliary stands A10 and B11. The mating parts of the auxiliary stands A10 and B11 with the insert plates 16 are provided with bolt positioning parts for fixing the auxiliary stands A10 and B11.

[0027] Sub-stands A10 and B11 are installed as a set on top of the shaping stands B8 and A6. During installation, after fitting sub-stands A10 and B11 onto the outside of the two insert plates 16, the sub-stands A10 and B11 are secured with bolts to complete the assembly. During disassembly, the bolts are released, and the sub-stands A10 and B11 are pulled out from the insert plates 16.

[0028] More specifically, the positioning element includes a fixing bolt 14, which is assembled on the outside of the sub-stands A10 and B11. The fixing bolt 14 passes through the sub-stands A10 and B11 and is threadedly connected to the threaded hole 15 on the outside of the insert plate 16. To improve the fastening effect, multiple sets of fixing bolts 14 can be provided on the outside of the sub-stands A10 and B11 to fix them to the insert plate 16, increasing the connection strength between the sub-stands A10 and B11 and the insert plate 16. Of course, as the number of fixing bolts 14 increases, the difficulty of assembling and disassembling the sub-stands A10 and B11 will also increase.

[0029] In a preferred embodiment, the insert plate 16 is a polygonal prism, and the sub-frames A10 and B11 have polygonal grooves in their centers that mate with the polygonal prism. The advantage of this design is that when the sub-frames A10 and B11 are fitted onto the outside of the insert plate 16, the insert plate 16, by engaging with the inner walls of the sub-frames A10 and B11, restricts their rotation, facilitating the positioning of the insert plate 16 by the locking and positioning components.

[0030] Regarding the supervisory body: The tube pushing mechanism includes a positioning plate 2, the lower end of which is fixedly connected to a fixed platform 1. Multiple guide grooves 3 are provided on the positioning plate 2, evenly distributed along the height of the positioning plate 2. Each guide groove 3 corresponds to a bending groove A12 and a bending groove B13, respectively. A feeding plate 4 is located on the side of the positioning plate 2 away from the shaping platform A6. A sliding table assembly B is provided between the feeding plate 4 and the fixed platform 1. The crossbeam pipe to be bent is placed in the corresponding guide groove 3 on the positioning plate 2. During bending, the sliding table assembly B pushes the feeding plate 4, causing it to press against one side of the crossbeam pipe. By moving the feeding plate 4, the pipe is pushed towards the shaping platform A6 and the shaping platform B8.

[0031] It is worth explaining in detail that both the fixed platform 1 and the power turntable 5 have a sliding groove 7 at their upper ends. The sliding groove 7 is connected to the transmission cavity opened inside the fixed platform 1 and the power turntable 5. A guide block 17 is provided in the sliding groove 7, and the guide block 17 is slidably connected to the sliding groove 7.

[0032] More specifically, slide assembly A and slide assembly B include a side support plate 9 and a screw drive component. The side support plate 9 is fixedly installed on the outside of the shaping frame B8 and the feeding plate 4. The lower end of the side support plate 9 is fixedly connected to the guide block 17. The screw drive component includes a motor 18, a nut seat 19 and a screw 20. The motor 18 is installed on the outside of the power turntable 5 and the fixed platform 1. The screw 20 is rotatably installed inside the transmission cavity. The nut seat 19 is sleeved on the outside of the screw 20 and threadedly connected to the screw 20. The nut seat 19 is fixedly connected to the lower end of the guide block 17.

[0033] When the motor 18 starts, it drives the screw 20 to rotate. As the screw 20 rotates, it engages with the nut seat 19, causing the nut seat 19 to move along the body of the screw 20. Since the lower end of the guide block 17 is fixed to the nut seat 19 and the upper end of the guide block 17 is fixed to the lower end of the side support plate 9, when the nut seat 19 moves along the body of the screw 20, the side support plate 9 will also be driven by the guide block 17, moving horizontally on the upper end of the fixed platform 1 and the power turntable 5, thus completing the pushing of the shaping platform B8 and the feeding plate 4.

[0034] Of course, in addition to screw drives, other linear adjustment mechanisms can be used as alternatives, such as cylinders and hydraulic cylinders, and are not limited to the one described above.

[0035] How this application works: The crossbeams of the chassis pipes that need to be bent are placed on the upper end of the fixed platform 1. The pipe pushing mechanism pushes the crossbeams towards the power turntable 5. After being pushed between the shaping platform A6 and the shaping platform B8, the slide assembly A pushes the shaping platform B8 towards the shaping platform A6. After the shaping platform A6 and the shaping platform B8 are closed, the crossbeams are limited by the bending grooves A12 and B13. The reduction motor at the bottom of the fixed platform 1 controls the rotation of the power turntable 5. During the rotation, the power turntable 5 completes the bending of multiple sets of crossbeams through the auxiliary platform A10 and the auxiliary platform B11. Sub-stands A10 and B11 are installed on the upper end of the standard stands A6 and B8. The detachable installation method makes it easy for staff to replace sub-stands A10 and B11 with different hole diameters. While retaining the original standard stands A6 and B8, they can be adapted to crossbeam pipes of different diameters.
