[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-5 , a bending device for a sheet metal part, including a positioning plate, a shaping mechanism with the shaping function of a multi-stage first electric push rod A2 is arranged on the positioning plate, the shaping mechanism includes a positioning block A3, a multi-stage first electric push rod B4, a positioning block B5 and a cylinder 8, the output ends of the multi-stage first electric push rod A2 and the multi-stage first electric push rod B4 are respectively fixedly connected with a positioning block A3 and a positioning block B5, the output end of the cylinder 8 is fixedly connected with a connecting block 9, and the connecting block 9 is fixedly connected with an "I"-shaped positioning block 10;

[0023] It also includes a fixed frame 7, an electric push rod 11 is horizontally installed on the fixed frame 7, and a pushing frame 12 is fixedly connected to the output end of the electric push rod 11.

[0024] In this embodiment, it also includes an operating table 1, a positioning groove 100 is opened on the operating table 1, a sheet metal part 6 is placed on the top surface of the operating table 1, and a fixed frame 7 is fixedly connected to the top surface of the operating table 1.

[0025] In this embodiment, positioning plates are fixedly connected to the tops of both sides of the operating table 1, and a multi-stage first electric push rod B4 and a multi-stage first electric push rod A2 are respectively installed on the two positioning plates from top to bottom.

[0026] In this embodiment, a cylinder 8 is vertically installed on the top of the fixed frame 7, and three electric push rods 11 are horizontally installed on one side surface of the fixed frame 7, and the three electric push rods 11 are jointly fixedly connected with a pushing frame 12.

[0027] In this embodiment, the two multi-stage first electric push rods A2, the two multi-stage first electric push rods B4, the cylinder 8 and the three electric push rods 11 are all externally connected to a power source.

[0028] In this embodiment, the "I"-shaped positioning block 10 is located above the sheet metal part 6, and the positioning block A3 and the positioning block B5 are located on both sides of the sheet metal part 6.

[0029] Usage method and advantages of the present utility model: When the bending of this kind of sheet metal part is in use, the working process is as follows:

[0030] As Figure 1 shown in the state, in step one, the operator first places the sheet metal part 6 on the operation table 1 and under the "I"-shaped positioning block 10 and on both sides of the positioning block B5 and the positioning block A3. This is the working procedure for the placement stage of the sheet metal part 6;

[0031] As Figure 2 shown in the state, in step two, the operator turns on the air cylinder 8. The output end of the air cylinder 8 is pushed out from the input end, driving the connecting block 9 and the "I"-shaped positioning block 10 to fall. The gradual fall of the "I"-shaped positioning block 10 contacts the sheet metal part 6, changing its original "one"-shaped structure into a "U"-shaped structure. This is the preliminary shaping procedure for the sheet metal part 6;

[0032] As Figure 3 shown in the state, in step three, the operator turns on two multi-stage first electric push rods A2. The output ends of the two multi-stage first electric push rods A2 are pushed out from the input ends, driving the positioning block A3 to be pushed out. At this time, as the positioning block A3 contacts the sheet metal part 6, the sheet metal part 6 is shaped again. This is the re-shaping procedure for the sheet metal part 6;

[0033] As Figure 4 shown in the state, in step four, the operator turns on two multi-stage first electric push rods B4. The output ends of the two multi-stage first electric push rods B4 are pushed out from the input ends, driving the positioning block B5 to be pushed out. At this time, as the positioning block B5 contacts the sheet metal part 6, the sheet metal part 6 is finally shaped into an "I"-shaped structure. This is the final shaping procedure for the sheet metal part 6; Through the operations of the above four steps, the sheet metal part 6 can quickly achieve the advantage of one-time forming, avoiding the trouble of the operator placing it on a bending machine for multiple bendings;

[0034] As Figure 5 shown in the state, the operator starts the air cylinder 8 to make the air cylinder 8 drive the connecting block 9 and the "I"-shaped positioning block 10 to reset. The output end of the air cylinder 8 resets to the input end. At this time, the connecting block 9 and the "I"-shaped positioning block 10 drive the sheet metal part 6 to rise. After the rising stops, the operator starts three electric push rods 11. The output ends of the three electric push rods 11 output from the input ends and drive the push frame 12 to push horizontally. As the push frame 12 contacts the sheet metal part 6, the sheet metal part 6 is horizontally pushed out from the "I"-shaped positioning block 10. At this time, the operator can catch the positioning block B5 with his hand. This is the automatic pushing-out procedure for the sheet metal part 6. Through the above operations, the risk of being pinched or scratched by mechanical parts during manual part picking can be avoided, and this risk is reduced by automatically pushing out through the electric push rods 11 driving the push frame 12.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
