Furthermore, the support used for forming the drum body mostly employs fixed rigid molds or simple roller supports, which can cause deformation and indentation of the drum wall due to localized stress. Additionally, the diameter cannot be dynamically adjusted. When pressing the weld seams, manual hammering or simple rolling is often used, a method that relies heavily on manual experience and has low processing efficiency.

[0018] Compared with the prior art, the present invention provides an automatic forming machine for producing iron drum bodies, which has the following beneficial effects:

[0019] This automatic forming machine for producing iron drum bodies, through its inner cylinder shaping column and adjustable flap mold assembly, can perform inner and outer wall forming processes on the bent iron drum body raw material. The inner cylinder shaping column can be disassembled and replaced, and the eight adjustable flap mold assemblies can be moved. Based on this, it can adapt to the forming work of iron drum bodies of various sizes.

[0020] The automatic forming machine for producing the iron drum body can move the positioning wheel by starting the first rotary motor, which can be driven by the auxiliary positioning component. The moved positioning wheel can fit against the inner wall of the iron drum body to complete the positioning of the iron drum body. With the help of the second rotary motor and the rotating shaft, the iron drum body can be rotated. This makes it convenient to move the iron drum body to a suitable work position for welding and weld seam pressing.

[0021] The automatic forming machine for producing iron drum bodies uses two welding robots that can weld the inner and outer walls of the iron drum through the first and second welding clearance grooves, facilitating the direct forming of the bent iron drum body material. The heat dissipation mesh plate facilitates heat dissipation for the inner cylinder shaping column, and the heat dissipation mesh plate is removable, making it convenient for subsequent maintenance of the welding robots in the inner cavity.

[0022] This automatic forming machine for producing iron drum bodies uses a linear motor and a drive motor to move and rotate the pressing components. After the iron drum body is welded, the pressing rollers are brought into contact with the weld seam, and the weld seam is then pressed. Through the first spring and the connecting arm connected by the damping shaft, the pressing rollers can be adapted to the size of the weld seam and the position of the pressing rollers can be automatically adjusted according to the size of the weld seam. Based on this, it can be ensured that the pressing rollers can fit perfectly with the weld seam. Moreover, the two pressing components can press the inner and outer wall weld seams of the iron drum body simultaneously, thus forming a two-way constraint to prevent the iron drum body from deforming after welding.

[0023] This automatic forming machine for producing iron drum bodies uses a positioning groove and a positioning block. When the adjustable mold assembly moves according to the required size of the iron drum body, the positioning block can be inserted into the inner cavity of the positioning groove to position the adjustable mold assembly. Based on this, the adjusted mold assembly can be reinforced after movement to improve the forming accuracy of the iron drum body. By energizing the electromagnet, the electromagnet can attract the iron core, allowing the iron core to lift the positioning block. When the adjustable mold assembly moves to the appropriate positioning groove, the electromagnet is de-energized. With the help of the third spring, the positioning block can be quickly inserted into the inner cavity of the positioning groove through the connecting block, completing the reinforcement of the adjustable mold assembly.

[0024] The automatic forming machine for producing the iron drum body uses a liftable lifting assembly to move the second conical push plate up and down. When the second conical push plate moves to the bottom, it can squeeze the first conical push plate. Since the bottom of the first conical push plate is movably connected to the guide rail, the first conical push plate can move radially after being squeezed. At this time, the eight adjustable petal mold assemblies can move simultaneously until they move to the size that meets the forming requirements of the iron drum body.

[0025] The automatic forming machine for producing iron drum bodies uses a fixed rod to move the outer wall of the first conical push plate as it moves, thus further limiting the movement of the first conical push plate. At the same time, it compresses the second spring. After the iron drum body is produced, the second conical push plate returns to its original position, and the second spring drives the first conical push plate to return to its original position, facilitating subsequent production of iron drum bodies.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1:

An inner cylinder shaping column 5 is rotatably connected to the top of the forming machine body 1. Adjustable flap mold assemblies 19 are movably connected to the outer wall of the inner cylinder shaping column 5. There are eight adjustable flap mold assemblies 19. Auxiliary positioning assemblies 9 are symmetrically rotatably connected to the inner cavities on both sides of the inner cylinder shaping column 5. Welding robots 2 are installed on both the outer wall of the forming machine body 1 and the inner cavity of the inner cylinder shaping column 5. A second welding clearance groove 21 is formed on the outer wall of one of the adjustable flap mold assemblies 19, and a first welding clearance groove 6 is formed on the outer wall of the inner cylinder shaping column 5. The first welding clearance groove 6 and the second welding clearance groove 21 are used by the welding robot 2 to pass through the inner cylinder shaping column 5 and the adjustable flap mold assemblies 19. The adjustable petal mold assembly 19 is welded. A heat dissipation mesh plate 7 is provided in the center of the top of the inner cylinder shaping column 5. A top plate 38 is installed on the top of the inner cavity of the molding machine body 1. A second rotary motor 39 is installed on the top of the top plate 38. A rotating shaft 40 is installed on the top of the second rotary motor 39 through a coupling. The rotating shaft 40 is installed in the center of the bottom of the inner cylinder shaping column 5. Accommodating grooves 8 are symmetrically provided on both sides of the inner cylinder shaping column 5. An auxiliary positioning assembly 9 is movably connected in the inner cavity of the accommodating groove 8. A positioning wheel 10 is rotatably connected in the center of the top of the auxiliary positioning assembly 9. A first rotary motor 11 is installed in the inner cavity of the accommodating groove 8. The first rotary motor 11 is connected to the bottom of the auxiliary positioning assembly 9 through a first rotating shaft.

[0037] With the inner cylinder shaping column 5 and the adjustable petal mold assembly 19, the inner and outer walls of the bent iron drum body raw material can be formed. The inner cylinder shaping column 5 can be disassembled and replaced, and the eight adjustable petal mold assemblies 19 can be moved. Based on this, it can be adapted to form iron drum bodies of various sizes.

[0038] By activating the first rotary motor 11, the positioning wheel 10 can be moved by the auxiliary positioning component 9. After the positioning wheel 10 is moved, it can fit against the inner wall of the iron drum body to complete the positioning of the iron drum body. In conjunction with the second rotary motor 39 and the rotating shaft 40, the iron drum body can be rotated. Based on this, it is convenient to move the iron drum body to a suitable work position for welding and weld seam pressing.

[0039] With the two welding robots 2 set up, they can perform welding work on the inner and outer walls of the iron drum through the first welding clearance groove 6 and the second welding clearance groove 21, which facilitates the direct forming of the bent iron drum body material. The heat dissipation mesh plate 7 facilitates heat dissipation for the inner cylinder shaping column 5. At the same time, the heat dissipation mesh plate 7 is detachable, which facilitates the subsequent maintenance of the welding robots 2 in its inner cavity.

[0040] Example 2:

[0041] like Figures 1-6As shown, an automatic forming machine for producing iron drum bodies includes an adjustable mold assembly 19 and an inner cylinder shaping column 5, which are symmetrically and movably connected to a pressing assembly 14 on opposite sides. A positioning groove 4 is provided on the top of the forming machine body 1. Positioning blocks 31 are symmetrically and movably connected to the bottom of both sides of the adjustable mold assembly 19. A heat dissipation mesh 20 is installed on the outer wall of the adjustable mold assembly 19. A lifting groove 12 is symmetrically provided on opposite sides of the inner cylinder shaping column 5 and one of the adjustable mold assemblies 19. A straight... One side of the pressing assembly 14 is connected to the linear motor 13, and the other side of the pressing assembly 14 is equipped with a drive motor 15 via a second rotating shaft. The drive motor 15 is vertically and movably connected to the other side of the inner cavity of the lifting groove 12. A limit groove is formed on the top of the pressing assembly 14. The pressing assembly 14 is close to the outer wall of the inner cylinder shaping column 5 and the adjustable flap mold assembly 19. First springs 17 are symmetrically installed on both sides of the inner wall of the limit groove. The other end of the first spring 17 is connected to a connecting arm 16. The connecting arm 16 is rotatably connected to the lifting groove 12 via a torque shaft. A pressing wheel 18 is rotatably connected to the top of the inner cavity of the pressing assembly 14 and the top of the inner cavity of the connecting arm 16. There are sixty-four positioning grooves 4, which are arranged in groups of eight. Each group of positioning grooves 4 is respectively set on both sides of the movable groove 3. The size of the positioning block 31 is adapted to the positioning groove 4, and the positioning block 31 is inserted into the inner cavity of one of the positioning grooves 4. The bottom of both sides of the adjustable flap assembly 19 is symmetrically provided with adjustment grooves 42. An electromagnet 41 is installed at the top of the inner cavity of the adjustment groove 42, and a limit plate 26 is installed in the center of the inner cavity of the adjustment groove 42. A core 27 is movably connected to the inner cavity of the limiting plate 26. A connecting post 28 is installed at the bottom of the core 27. A connecting block 30 is installed at the bottom of the connecting post 28. The center of the bottom of the connecting block 30 is installed on the top of the positioning block 31. A third spring 29 is wound around the outer wall of the connecting post 28. The top of the third spring 29 is installed on the bottom of the limiting plate 26. The bottom of the third spring 29 is installed on the top of the connecting block 30. The connecting block 30, the positioning block 31, the connecting post 28, and the third spring 29 are all movably connected to the inner cavity of the adjusting groove 42.

[0042] The linear motor 13 and drive motor 15 can drive the pressing assembly 14 to move up and down and rotate. After the iron drum body is welded, the pressing wheel 18 can be driven to fit against the weld. At this time, the weld can be pressed. The first spring 17 and the connecting arm 16 connected by the damping shaft can make the pressing wheel 18 adapt to the size of the weld. The position of the pressing wheel 18 can be automatically adjusted according to the size of the weld. Based on this, it can be ensured that the pressing wheel 18 can fit perfectly against the weld. The two pressing assemblies 14 can press against the inner and outer wall welds of the iron drum body at the same time, thus forming a two-way constraint to avoid the deformation of the iron drum body after welding.

[0043] With the positioning groove 4 and positioning block 31, when the adjustable petal mold assembly 19 moves according to the required forming size of the iron barrel body, the positioning block 31 can be inserted into the inner cavity of the positioning groove 4 to complete the positioning of the adjustable petal mold assembly 19. Based on this, the adjusted petal mold assembly 19 after movement can be reinforced to improve the forming accuracy of the iron barrel body. By energizing the electromagnet 41, the electromagnet 41 can attract the iron core 27, so that the iron core 27 can lift the positioning block 31. When the adjustable petal mold assembly 19 moves to the appropriate positioning groove 4, the electromagnet 41 is de-energized. With the help of the third spring 29, the positioning block 31 can be quickly inserted into the inner cavity of the positioning groove 4 through the connecting block 30 to complete the reinforcement of the adjustable petal mold assembly 19.

[0044] Example 3:

[0045] like Figure 1 , Figure 5 , Figure 7 As shown, an automatic forming machine for producing iron drum bodies has a movable groove 3 on the top of the forming machine body 1. A first conical push plate 22 is installed at the bottom of an adjustable 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 two 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 at an angle of 45 degrees. The first conical push plate 22 and the second conical push plate 33 are attached together by the inclination. The first conical push plate 22 is movably connected in 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 lead screw 37 is installed at the top of the servo motor 36 through a third rotating shaft. The top of the lead screw 37 is rotatably connected to the bottom of the top plate 38. The lifting assembly 32 is threadedly connected to the outer wall of the lead screw 37. A limit block 34 is installed in the inner cavity of the molding machine body 1. A guide rod 35 is installed at the bottom of the lifting assembly 32. The guide rod 35 is movably connected in the inner cavity of the limit block 34.

[0046] The lifting assembly 32 can drive the second conical push plate 33 to move up and down. 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 valve mold assemblies 19 can move simultaneously until they move to the size that conforms to the forming of the iron barrel body.

[0047] The fixed rod 24 moves along the outer wall of the first conical push plate 22 as it moves, which further limits the movement of the first conical push plate 22 and squeezes the second spring 25. After the iron drum body is produced, the second conical push plate 33 resets, and the second spring 25 drives the first conical push plate 22 to reset, which facilitates the subsequent production of the iron drum body.

[0048] It should be noted that the present invention is an automatic forming machine for producing iron drum bodies. When in use, the inner cylinder shaping column 5 is replaced according to the required iron drum body size. After the replacement is completed, the material of the iron drum body is bent and then the iron drum body material is fitted onto the outer wall of the inner cylinder shaping column 5.

[0049] Start the servo motor 36 to drive the lead screw 37 to rotate, so that the lifting assembly 32 can be threadedly connected to it. The lifting assembly 32 can then move down. When the lifting assembly 32 moves down, it will drive the guide rod 35 to move in the inner cavity of the limit block 34. At the same time, it will drive the second conical push plate 33 to squeeze the first conical push plate 22. After being squeezed, the first conical push plate 22 will move radially. The bottom of the first conical push plate 22 will move on the outer wall of the guide rail 23, and the side of the first conical push plate 22 will move on the outer wall of the fixed rod 24 and squeeze the second spring 25.

[0050] When the electromagnet 41 is normally energized, the positioning block 31 is moved to the top of the inner cavity of the adjustment groove 42. After the first conical push plate 22 moves, it can drive the adjustable valve mold assembly 19 to move. After the adjustable valve mold assembly 19 is fitted into the appropriate position, the electromagnet 41 is de-energized. At this time, the iron core 27 is disengaged from the electromagnet 41, and the third spring 29 pushes the connecting block 30 to the bottom, so that the positioning block 31 can be inserted into the corresponding positioning groove 4 inner cavity. At this time, the fixing and positioning process of the adjustable valve mold assembly 19 is completed.

[0051] Start the first rotary motor 11, which drives the positioning wheel 10 to rotate through the auxiliary positioning component 9 until the positioning wheel 10 is in contact with the inner wall of the iron drum body. At this time, the positioning of the iron drum body is completed. Adjust the position of the iron drum body according to the welding position as needed. Start the second rotary motor 39, which drives the iron drum 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 to weld the inner wall and outer wall of the iron drum body at the same time.

[0052] After welding is completed, continue to rotate the iron drum body until the weld seam of the iron drum body is rotated between the two pressing components 14. Start the drive motor 15, and drive the pressing roller 18 to fit against the weld seam through the pressing components 14 and the connecting arm 16. Start the linear motor 13 to drive the pressing roller 18 to move up and down. At this time, the weld seam can be pressed. After pressing is completed, the forming work of the iron drum body can be completed. The electromagnet 41 is energized to attract the iron core 27, and the positioning block 31 is disengaged from the inner cavity of the positioning groove 4. 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 disengaged from the outer wall of the iron drum body. At this time, the iron drum body can be taken out.

[0053] The heat dissipation mesh 7 and heat dissipation mesh 20 can dissipate heat from the corresponding components during the forming process of the iron drum body. The inner cylinder shaping column 5 and the adjustable valve mold assembly 19 can provide good inner and outer wall support during the forming process of large-diameter iron drum bodies. When welding the iron drum body and pressing the weld seam, they can evenly distribute stress and prevent shrinkage during forming.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
