[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 2 An embodiment of the utility model provides a press forming device for boiler components, including: a bottom plate 1 and a vertical plate 2.

[0020] Among them, Figure 1 and Figure 2 As shown, the vertical plate 2 is installed on the top of the base plate 1, and a forward and reverse motor 8 is installed on the top of the base plate 1. A threaded rod 5 is rotatably installed inside the vertical plate 2, and one end of the threaded rod 5 and the rotating shaft of the forward and reverse motor 8 are both installed with a first gear 9, and the two first gears 9 are meshed with each other. A slide rail 15 is provided on the top of the base plate 1, and a first movable plate 3 is slidably installed on the slide rail 15. An internal threaded cylinder 14 is embedded in the interior of the first movable plate 3, and one end of the threaded rod 5 is threadedly connected to the interior of the internal threaded cylinder 14. A first limiting cylinder 6 is installed on one side of the vertical plate 2 through a bearing, and a second limiting cylinder 7 is installed on one side of the first movable plate 3 through a bearing.

[0021] When in use, one end opening of the cylindrical boiler liner is inserted into the first limiting cylinder 6, and the first movable plate 3 located on the slide rail 15 is pushed, so that one end of the threaded rod 5 is inserted into the opening of the internal threaded cylinder 14, and the two first gears 9 are meshed and transmitted by starting the forward and reverse motor 8, and the threaded rod 5 is driven clockwise to gradually screw into the internal threaded cylinder 14, driving the first movable plate 3 and the second limiting cylinder 7 to move to and insert into the other end opening of the boiler liner, so that the first limiting cylinder 6 and the second limiting cylinder 7 automatically form a clamping state for the boiler liner.

[0022] Furthermore, in order to prevent the first movable plate 3 from being separated from the slide rail 15 , a baffle 17 is fixedly connected to the end of the slide rail 15 .

[0023] Among them, Figure 1-Figure 4 As shown, a rodless cylinder 16 is installed on the top of the base plate 1, and a second movable plate 4 is installed on the rodless cylinder 16 through a slide, a hydraulic cylinder 18 is installed inside the second movable plate 4, and the piston rod of the hydraulic cylinder 18 is fixedly connected to a roller wheel 13, a servo motor 20 is installed on one side of the first movable plate 3, and a gear ring 21 is installed on the outer wall of the second limiting cylinder 7, the rotating shaft of the servo motor 20 passes through the first movable plate 3, and is fixedly connected to a second gear 19, and the second gear 19 is meshed with the gear ring 21.

[0024] Start the servo motor 20, so that the second gear 19 drives the gear ring 21 to rotate, driving the second limit cylinder 7, the first limit cylinder 6 and the boiler liner to rotate. When the rodless cylinder 16 is running, it can drive the first movable plate 3 to move horizontally to the left and right, and after the hydraulic cylinder 18 is started, the roller wheel 13 can move and squeeze on the outer wall of the boiler liner to rotate, continuously apply pressure and overflow horizontally to the left and right, so that multiple circles of depressions are formed on the surface of the boiler liner, thereby forming a corrugated boiler liner.

[0025] It should be noted that after the corrugated furnace is rolled and pressed, the threaded rod 5 is reversed by the forward and reverse motor 8 in the counterclockwise direction, so that the first movable plate 3 and the second limiting cylinder 7 are gradually moved out from the threaded rod 5 .

[0026] For further reference, Figure 1 and Figure 4 A fixed cover 10 is fixedly connected to the rear surface of the second movable plate 4. After the fixed cover 10 is installed, it can cover and protect the hydraulic cylinder 18 inside the second movable plate 4, and after the fixed cover 10 is removed, the hydraulic cylinder 18 can be maintained and inspected.

[0028] Specifically, a plurality of connecting plates 12 are installed at the bottom of the base plate 1 , and threaded holes are provided on the connecting plates 12 . The bottom of the base plate 1 can be fixed to a designated area through the connecting plates 12 and fixing bolts.

[0029] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the utility model is used, one end opening of the cylindrical boiler liner is inserted into the first limiting cylinder 6, and the first movable plate 3 located on the slide rail 15 is pushed, so that one end of the threaded rod 5 is inserted into the opening of the internal threaded cylinder 14, and the two first gears 9 are meshed and transmitted by starting the forward and reverse motor 8, and the threaded rod 5 is driven clockwise to gradually screw into the internal threaded cylinder 14, driving the first movable plate 3 and the second limiting cylinder 7 to move to and insert into the other end opening of the boiler liner, so that the first limiting cylinder 6 and the second limiting cylinder 7 automatically form a clamping state for the boiler liner.

[0030] At this time, by starting the servo motor 20, the second gear 19 drives the gear ring 21 to rotate, driving the second limit cylinder 7, the first limit cylinder 6 and the boiler liner to rotate. When the hydraulic cylinder 18 is started, the roller wheel 13 can move and squeeze on the outer wall of the boiler liner to rotate, and continue to apply pressure to form multiple circles of depressions on the surface of the boiler liner, thereby forming a corrugated furnace liner. After the corrugated furnace liner is rolled and pressed into shape, the threaded rod 5 is reversed by the forward and reverse motor 8 in the counterclockwise direction, so that the first movable plate 3 and the second limit cylinder 7 are gradually moved out from the threaded rod 5.
