[0015] Compared with the prior art, the present invention provides an automatic forming machine for producing iron drum bodies, which has the following beneficial effects: The automatic forming machine for the production of iron barrel bodies can form the inner and outer walls of the bent iron barrel body raw materials through the inner barrel forming columns and adjustable flap mold components. The inner barrel forming columns can be disassembled and replaced, and the eight adjustable flap mold components can be moved. Based on this, it can adapt to various sizes of iron barrel bodies for forming.

[0016] The automatic forming machine for the production of iron barrel bodies can start the first rotating motor and drive the positioning wheel to move through the auxiliary positioning component. The moved positioning wheel can fit the inner wall of the iron barrel body to complete the positioning of the iron barrel body. In conjunction with the second rotating motor and the rotating shaft, the iron barrel body can be driven to rotate, which facilitates the subsequent movement of the iron barrel body to a suitable work station for welding and weld pressing.

[0017] The automatic forming machine for the production of iron barrel bodies is equipped with two welding robots, which can weld the inner and outer walls of the iron barrel body through the first welding clearance groove and the second welding clearance groove, so as to facilitate the direct forming of the bent iron barrel body material.

[0027] Example 3: like Figure 1 、 Figure 5 、 Figure 7 As shown, an automatic forming machine for producing iron barrel bodies is provided. A movable groove 3 is provided on the top of the forming machine body 1. A first conical push plate 22 is installed at the bottom of the adjustable flap mold assembly 19. A guide rail 23 is installed in the inner cavity of the forming machine body 1. A lifting assembly 32 is movably connected to the inner cavity of the forming machine body 1. A second conical push plate 33 is installed on the top of the lifting assembly 32. The bottom of the first conical push plate 22 is movably connected to the outer wall of the guide rail 23. A fixing rod 24 is installed in the inner cavity of the forming machine body 1. A second spring 25 is wound around the outer wall of the fixing rod 24. One end of the second spring 25 is connected to the first conical push plate 22, and the other end of the second spring 25 is connected to the inner cavity of the forming machine body 1. The first conical push plate 22 is sleeved on the outer wall of the fixing rod 24. The number of the second conical push plates 33 is the same as that of the first conical push plate 22. The opposite sides of the first conical push plate 22 and the second conical push plate 33 are both inclined, and the angle is forty-five degrees. The first conical push plate 22 and the second conical push plate 33 fit together through the inclined shape. The first conical push plate 22 is movably connected to the inner cavity of the movable groove 3. A servo motor 36 is installed at the bottom of the inner cavity of the molding machine body 1. A screw rod 37 is installed on the top of the servo motor 36 through a third rotating shaft. The top of the screw rod 37 is rotatably connected to the bottom of the top plate 38.

When the second conical push plate 33 moves to the bottom, it can squeeze the first conical push plate 22. Since the bottom of the first conical push plate 22 is movably connected to the guide rail 23, the first conical push plate 22 can move radially after being squeezed. At this time, the eight adjustable flap mold assemblies 19 can move simultaneously until they move to the size that meets the forming size of the iron barrel body. By setting the fixing rod 24, the outer wall of the first conical push plate 22 will move when the first conical push plate 22 moves. At this time, the movement of the first conical push plate 22 can be further limited, and the second spring 25 will be squeezed at the same time. When the production of the iron barrel body is completed, after the second conical push plate 33 is reset, the second spring 25 can drive the first conical push plate 22 to reset, which is convenient for the subsequent production of the iron barrel body.

[0028] It should be noted that the present invention is an automatic forming machine for producing iron barrel bodies. When in use, the inner barrel shaping column 5 is replaced according to the size of the iron barrel body to be formed. After the replacement is completed, the material of the iron barrel body is bent, and after bending, the iron barrel body material is sleeved on the outer wall of the inner barrel shaping column 5; The servo motor 36 is started to drive the screw rod 37 to rotate, so that the lifting assembly 32 can be threadedly connected to it. The lifting assembly 32 can now move downward. When the lifting assembly 32 moves downward, it drives the guide rod 35 to move in the inner cavity of the limit block 34, and at the same time drives the second conical push plate 33 to squeeze the first conical push plate 22.

After the first conical push plate 22 moves, the adjustable flap mold assembly 19 can be driven to move. After the adjustable flap mold assembly 19 is fitted to a suitable position, the electromagnet 41 is powered off. At this time, the iron core 27 is separated from the electromagnet 41, and the third spring 29 bounces the connecting block 30 to the bottom, so that the positioning block 31 can be inserted into the corresponding inner cavity of the positioning groove 4. At this time, the fixing and positioning of the adjustable flap mold assembly 19 is completed; Start the first rotary motor 11, and drive the positioning wheel 10 to rotate through the auxiliary positioning assembly 9 until the positioning wheel 10 is in contact with the inner wall of the iron barrel body. At this time, the positioning of the iron barrel body is completed. The position of the iron barrel body is adjusted according to the welding position of the iron barrel body as needed. Start the second rotary motor 39, and drive the iron barrel body on the outer wall of the inner cylinder shaping column 5 to rotate through the rotating shaft 40 until the first welding clearance groove 6 and the second welding clearance groove 21 are on the same axis. Start the two welding robots 2 and weld the inner and outer walls of the iron barrel body at the same time. After welding is completed, the iron barrel body is continued to be driven to rotate until the weld of the iron barrel body is rotated between the two pressing assemblies 14, and the driving motor 15 is started to drive the pressing wheel 18 to fit the weld through the pressing assembly 14 and the connecting arm 16, and the linear motor 13 is started to drive the pressing wheel 18 to move up and down, and the weld can be pressed. After the pressing is completed, the forming work of the iron barrel body can be completed, and the electromagnet 41 is energized to adsorb the iron core 27, and the positioning block 31 is separated from the inner cavity of the positioning groove 4, and the second conical push plate 33 is lifted. At this time, the second spring 25 can drive the first conical push plate 22 to move accordingly until the adjustable flap mold assembly 19 is separated from the outer wall of the iron barrel body, and the iron barrel body can be taken out; The heat dissipation mesh plate 7 and the heat dissipation mesh 20 can dissipate heat for the corresponding components when the iron barrel body is being formed. The inner cylinder shaping column 5 and the adjustable flap mold assembly 19 can provide better support for the inner and outer walls when the iron barrel body is being formed. When the iron barrel body is being welded and the welds are pressed, the stress can be evenly dispersed, thereby avoiding the shrinkage phenomenon during forming.
