Example 1:

as shown in fig. 1 and 2, a simple tool for air duct flanging comprises a bearing plate 1 for bearing a to-be-formed plate 5 and a turnover plate 2 for extruding the to-be-formed plate 5, the same side end parts of the bearing plate 1 and the turnover plate 2 are connected through a rotating part, the end parts of the bearing plate 1 and the turnover plate 2, which are far away from the rotating part, are provided with force applying rods 4 convenient to rotate, and the outer side surface of the turnover plate 2 can be pressed down to the inner side surface of the bearing plate 1 and realizes the right-angle flanging of the to-be-formed plate 5.

The bearing plate 1 and the turnover plate 2 are rectangular right angle steel, the length is larger than a to-be-formed plate 5, the rotating piece is T-shaped and comprises a fixed rod 3.1 and a winding rod 3.2, wherein the fixed rod 3.1 is fixedly connected between two inner side faces of the bearing plate 1, the two inner side faces are symmetrical relative to a coincident line, one end of the winding rod 3.2 is rotatably connected onto the fixed rod 3.1, the other end of the winding rod is fixedly welded at the seam of the inner side face of the turnover plate 2, and welding stability is guaranteed.

In this embodiment, the fixed rod 3.1 is a threaded rod, the end of the winding rod 3.2 close to the fixed rod 3.1 is provided with a nut 3.3 for being in threaded connection with the fixed rod 3.1, the nut 3.3 is located at the center of the fixed rod 3.1, when the winding rod 3.2 rotates, the displacement of the nut 3.3 along the length direction of the fixed rod 3.1 can be ignored, and the fixed rod 3.1 is realized by setting the number and the distance of threads on the fixed rod 3.1 in advance.

In this embodiment, around pole 3.2 when the pole 3.1 rotation is decided to the winding, the application of force sense is obvious, and after the operation was accomplished in addition, the returning face plate 2 can be stably accomodate in bearing board 1 inboard, and can not take place to rock.

In order to ensure the compactness of the whole structure, avoid the interference of the plate to be formed 5 and conveniently apply force, two force applying rods 4 are respectively welded at the joint of the outer side surface of the bearing plate 1 and the joint of the inner side surface of the turnover plate 2; when the turnover plate 2 and the bearing plate 1 are in a pressing position, the bearing plate 1 and the turnover plate 2 are parallel and the forming gap is less than or equal to 1mm, so that the smooth forming of the plate to be formed 5 is ensured.

Example 2:

as shown in fig. 3 and 4, embodiment 2 differs from embodiment 1 in that: the fixed rod 3.1 is a polished rod, one end of the winding rod 3.2 close to the fixed rod 3.1 is provided with a circular ring 3.4 which is used for being rotatably sleeved with the fixed rod 3.1, the circular ring 3.4 is positioned at the central position of the fixed rod 3.1, and the fixed rod 3.1 is provided with a clamping block 3.5 which limits the sliding of the circular ring 3.4.

Compare decide pole 3.1 and be the embodiment 1 of threaded rod, the structure shaping accuracy of embodiment 2 is higher, but when the construction, the application of force is not very convenient relatively, and after the operation, the returning face plate 2 is not well accomodate.
