[0039] The present utility model provides a bending and forming device for thin-walled sheet metal parts, including a base 2, positioning columns 3, positioning blocks 4, a bending mechanism 5, positioning clamps 6, cushion blocks 7, and positioning bolts 8. The thin-walled sheet metal part 1 includes two bending parts 11 and a fixing part 12, and the bending part 11 is connected to the fixing part 12. The following will Figures 1 - 7 elaborate in detail on the bending and forming device for thin-walled sheet metal parts and the structures of each component.

[0040] The bending and forming device for thin-walled sheet metal parts includes:

[0041] As Figure 4 shown, the base 2 is provided with a positioning column hole A;

[0042] As Figures 1 - 2 shown, the positioning column 3 passes through the positioning column hole A and is vertically fixed on the base 2 for fixing the thin-walled sheet metal part 1, and the two bending parts 11 of the thin-walled sheet metal part 1 are sleeved on the positioning column 3; the positioning block 4 is vertically fixed on the base 2 and is arranged in a staggered manner with the positioning column 3, that is, the center line of the positioning block 4 and the center line of the positioning column 3 are not on the same straight line, and there is a gap between the positioning block 4 and the positioning column 3. When the bending part 11 is sleeved on the positioning column 3, the positioning block 4 fixes the fixing part 12;

[0043] Preferably, as Figure 3 and Figure 5As shown in the figure, a limiting bump 41 is provided at one end of the positioning block 4 close to the positioning post 3. When the bending part 11 is sleeved on the positioning post 3, the fixing part 12 is clamped on the limiting bump 41. Through the cooperation of the positioning post 3 and the positioning block 4, the thin-walled sheet metal part 1 can be stably and accurately positioned and fixed, preventing the thin-walled sheet metal part 1 from shifting during the bending process, thereby controlling the bending angle of the thin-walled sheet metal part 1 and keeping its shape and size consistent during the bending process.

[0044] The bending mechanism 5 is sleeved on the positioning post 3. By rotating the bending mechanism 5, the two bending parts 11 of the thin-walled sheet metal part 1 are bent along a set direction, so that a preset angle is formed between the bending part 11 and the fixing part 12.

[0045] Preferably, as Figures 1 - 2 shown, the bending mechanism 5 includes a rotating assembly 51 and a forming post 52:

[0046] The rotating assembly 51 is sleeved on the positioning post 3 and is located between the two bending parts 11;

[0047] The forming post 52 is perpendicular to the base and is located in the gap between the positioning block 4 and the positioning post 3. The forming post 52 is also connected to the rotating assembly 51. The forming post 52 is close to the connection part between the bending part 11 and the fixing part 12. By rotating the rotating assembly 51, the forming post 52 is driven to rotate around the positioning post 3, and the forming post 52 rotates to drive the two bending parts 11 to be bent, so that a preset angle is formed at the connection part between the bending part 11 and the fixing part 12. This preset angle is the preset bending angle of the thin-walled sheet metal part 1. By driving the bending part 11 to be bent through the rotation of the forming post 52, the uneven stress during the bending process can be reduced, thereby improving the bending forming quality. After the thin-walled sheet metal part 1 is installed and fixed, only by rotating the rotating assembly 51 can the bending operation be completed, which simplifies the operation process, reduces the need for manual adjustment, improves the bending efficiency and accuracy, ensures the consistency of the bending parts of each thin-walled sheet metal part 1 in mass production, and improves the overall quality.

[0048] As Figure 3 and Figure 7 shown, in some embodiments, a positioning clamp 6 is further included. A first threaded hole B is provided at the top of the positioning block 4. One end of the positioning clamp 6 is provided with a second threaded hole C corresponding to the first threaded hole B. The positioning clamp 6 is connected to the positioning block 4 through a positioning bolt 8. The other end of the positioning clamp 6 has a positioning post groove D, and the positioning post groove D is engaged and matched with the positioning post 3. By using the positioning clamp 6, the stability of the positioning post 3 can be further enhanced, ensuring that the position of the sheet metal part remains accurate during the bending process.

[0049] As Figure 3 and Figure 6As shown, in some embodiments, the rotating assembly 51 includes a sleeve 511 and a handle 512: The sleeve 511 is rotatably sleeved on the positioning column 3; the handle 512 is fixed to the sleeve 511 along the radial direction of the sleeve 511.

[0050] In some embodiments, the sleeve 511, the handle 512 and the forming column 52 are of an integral structure. Specifically, the sleeve 511, the handle 512 and the forming column 52 can be connected into an integral structure by welding.

[0051] In some embodiments, a cushion block 7 is further included, and the cushion block 7 is fixed below the base 2. It is used to provide additional support and enhance stability, especially when bending large-sized sheet metal parts. The cushion block 7 can also be used to adjust the height of the device to facilitate the bending and forming operation.

[0052] In some embodiments, the positioning block 4 is integrally formed.

[0053] In some embodiments, the positioning column 3 and the positioning block 4 are fixed to the base 2 by welding.

[0054] In some embodiments, the specification of the positioning bolt 8 is M16.

[0055] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
