DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Such as Figure 1 - Figure 4As shown in the figure, a bending device for an automotive pipe rack mainly includes a pipe rack round tube 8 to be processed and a set of carefully designed bending systems. This system takes the mounting plate 1 as the core, on which there are multiple mounting holes 2 distributed. These holes are equally spaced and in the shape of waist holes to adapt to the mounting requirements at different positions. In addition, a layer of rubber pad is adhered to the surface of the mounting plate 1 to increase stability and operating comfort. Viewed from above, the mounting plate 1 presents a unique triangular design, which is not only beautiful but also beneficial to the stability and force distribution of the device.

[0025] At the upper triangular part of the mounting plate 1, a first hydraulic cylinder 4, a second hydraulic cylinder 9, and a third hydraulic cylinder 12 are respectively arranged. These three hydraulic cylinders are all flexibly mounted in the mounting holes 2 through the position adjustment assembly 3. The position adjustment assembly 3 includes a mounting disc 31, a connecting stud 32, and a fastening nut 33. The connecting stud 32 is located at the lower end of the mounting disc 31, is inserted into the mounting hole 2, and is fixed using the fastening nut 33. By rotating the connecting stud 32, the telescopic direction of the hydraulic cylinder on the mounting disc 31 can be adjusted, so as to realize bending of the pipe rack round tube 8 to be processed at different positions and angles.

[0026] A bending seat 6 is provided on the first hydraulic cylinder 4. The bending seat 6 is tightly combined with the first hydraulic cylinder 4 through threaded connection. A bending cavity 7 adapted to the pipe rack round tube 8 to be processed is opened inside the bending seat 6. The design of this cavity enables the pipe rack round tube 8 to be processed to maintain a stable shape and position during the bending process. In addition, the middle part of the bending seat 6 is a straight-shaped sunk groove, and the width of this sunk groove is the same as the width of the bending cavity 7, which helps to enhance the bending accuracy and stability.

[0027] The telescopic ends of the second hydraulic cylinder 9 and the third hydraulic cylinder 12 are connected with a limiting head 10, and a pressing cylinder 11 is further connected through the limiting head 10. An annular groove is opened on the side wall of the pressing cylinder 11. This annular groove faces the bending cavity 7, and its width is the same as the width of the bending cavity 7. This design enables the pressing cylinder 11 to closely fit the pipe rack round tube 8 to be processed during the bending process, preventing it from shifting or deforming during the bending process.

[0028] During operation, by controlling the telescopic movements of the first hydraulic cylinder 4, the second hydraulic cylinder 9, and the third hydraulic cylinder 12, the bending seat 6 and the two pressing cylinders 11 can be driven to work together, so as to realize precise bending of the pipe rack round tube 8 to be processed. This device is not only compact in structure and easy to operate, but also has high bending accuracy and stability, and is suitable for the processing and manufacturing of high-precision parts such as automotive pipe racks.

[0029] Bending process: Place the round tube 8 of the pipe rack to be processed on a carefully designed bending device. Ensure that the round tube 8 of the pipe rack to be processed can be stably placed on the mounting plate 1 and aligned with the bending cavity 7 of the bending seat 6 and the annular groove of the pressing cylinder 11.

[0030] Next, by controlling the position adjustment component 3, adjust the position and direction of the first hydraulic cylinder 4, the second hydraulic cylinder 9, and the third hydraulic cylinder 12. Specifically, the telescopic direction of the hydraulic cylinders on the mounting disc 31 can be adjusted by rotating the connecting stud 32 to ensure that they can accurately act on the predetermined position of the round tube 8 of the pipe rack to be processed.

[0031] Then, start the first hydraulic cylinder 4, and its telescopic end drives the bending seat 6 to apply pressure to the round tube 8 of the pipe rack to be processed. The bending cavity 7 inside the bending seat 6 is in close contact with the round tube 8 of the pipe rack to be processed, ensuring that the round tube 8 of the pipe rack to be processed can maintain a stable shape and position during the bending process.

[0032] At the same time, start the second hydraulic cylinder 9 and the third hydraulic cylinder 12, and their telescopic ends push the limit head 10 and the pressing cylinder 11 to move towards the round tube 8 of the pipe rack to be processed. The annular groove on the side wall of the pressing cylinder 11 is directly opposite to the bending cavity 7, ensuring that it can be in close contact with the outside of the round tube 8 of the pipe rack to be processed during the bending process and providing the necessary support and fixation.

[0033] With the telescopic movement of the hydraulic cylinders, the bending seat 6 and the two pressing cylinders 11 work together to apply appropriate pressure and bending moment to the round tube 8 of the pipe rack to be processed. By precisely controlling the movement speed and force of the hydraulic cylinders, precise bending of the round tube 8 of the pipe rack to be processed can be achieved, reaching the predetermined bending angle and shape.

[0034] During the entire bending process, the rubber pad on the mounting plate 1 provides additional stability and buffering, ensuring that the round tube 8 of the pipe rack to be processed will not be subjected to excessive impact or damage during the bending process.

[0035] After the bending is completed, by controlling the contraction movement of the hydraulic cylinders, move the bending seat 6 and the pressing cylinder 11 away from the round tube 8 of the pipe rack to be processed, take out the round tube 8 of the pipe rack to be processed that has completed the bending, and prepare for the next processing or assembly work.

[0036] Through this carefully designed bending device and precise bending process, efficient and precise bending processing of the round tube of the automotive pipe rack can be achieved, improving production efficiency and product quality.
