Description
Technical Field
[0001] This utility model relates to the field of metal can processing technology, and in particular to a metal can bottom forming device. Background Technology
[0002] Metal cans are containers made of metal materials and are widely used in the food, beverage, chemical, and daily necessities industries. A metal can consists of a can body, a can bottom, and a can lid. The can bottom is formed by stamping a round piece during the production process.
[0003] During the production process, the bottom of the metal can is formed by stamping a disc using a stamping machine. During production, workers fill the disc manually. This process can easily cause crush injuries to the operators and is also inefficient, thus reducing the overall work efficiency of the workers. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a metal can bottom forming device.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a metal can bottom forming device, including a mounting platform, a rotating platform with an open top fixedly mounted on the upper surface of the mounting platform, a worktable rotatably mounted inside the rotating platform, a support frame with an L-shaped cross-section fixedly mounted on the upper surface of the mounting platform, a stamping cylinder fixedly mounted on the horizontal upper surface of the support frame, the piston rod end of the stamping cylinder penetrating the support frame, a can bottom forming part fixedly mounted on the piston rod end of the stamping cylinder, a plurality of mounting slots distributed in a circumferential array on the upper surface of the worktable, and a control device for controlling the rotation of the worktable provided inside the rotating platform, the control device including a control component and a drive component.
[0006] By adopting the above technical solution, when workers need to produce the bottom of metal cans, they need to place a round piece into the placement slot. Then, the worker needs to activate the stamping cylinder, causing the piston rod of the stamping cylinder to move downwards, thereby causing the can bottom forming component installed at the end of the piston rod to stamp the round piece into the bottom of the metal can. After stamping is completed, the worker needs to control the worktable to rotate, so that the other placement slots are aligned with the stamping cylinder. At this point, the worker can remove the stamped metal can from the placement slot. This process reduces the probability of worker injury and allows for the removal of the metal can bottom during stamping, thus improving worker efficiency.
[0007] Furthermore, the control component includes a connecting shaft fixedly mounted on the bottom surface of the worktable, a connecting plate fixedly mounted on the bottom surface of the connecting shaft, a rocker arm rotatably mounted inside the rotary table, a drive rod fixedly mounted on the upper surface of the rocker arm, and a rotating shaft rotatably mounted on the upper surface of the rocker arm. The upper surface of the connecting plate is provided with a plurality of drive grooves arranged in a circumferential array. The drive rod matches the drive grooves. The rotating shaft is fixed to the inner wall of the rotary table by a mounting component.
[0008] Furthermore, the drive assembly includes an electric cylinder fixedly mounted on the inner wall of the rotary table, a rotating rod fixedly mounted on the bottom surface of the rocker arm, and a connecting rod rotatably mounted on the end of the rotating rod away from the rocker arm. The end of the connecting rod away from the rotating rod is rotatably connected to the piston rod of the electric cylinder.
[0009] By adopting the above technical solution, when the worker needs to rotate the worktable, the worker needs to activate the electric cylinder, which extends the piston rod of the electric cylinder, causing the connecting rod and the rotating rod to rotate. During this process, the connecting rod and the rotating rod rotate relative to each other. When the piston rod of the electric cylinder completes one extension and retraction, the rotating rod rotates 360 degrees under the action of the connecting rod (the specific working principle can be referred to the crank-slider mechanism). Subsequently, after the rotating rod rotates 360 degrees, the rocker arm rotates 360 degrees along the axis of rotation under the action of the rotating rod, which in turn causes the drive rod to rotate 360 degrees along the axis of rotation under the action of the rocker arm. This causes the connecting plate to rotate 90 degrees under the action of the drive rod, which in turn causes the connecting shaft to rotate 90 degrees under the action of the connecting plate. This causes the worktable to rotate 90 degrees under the action of the connecting shaft, thus aligning the placement slot with the piston rod of the stamping cylinder. At this time, the worker can remove the stamped metal can from the placement slot. In this process, the probability of worker injury is reduced, and the bottom of the metal can can also be removed during the stamping process, thereby improving the worker's work efficiency.
[0010] Furthermore, a rotating seat is fixedly provided at the end of the piston rod of the electric cylinder, and the rotating seat is rotatably connected to the end of the connecting rod away from the rotating rod.
[0011] By adopting the above technical solution, when the electric cylinder piston rod extends and retracts, the rotating seat moves synchronously with the electric cylinder piston rod under the action of the electric cylinder piston rod. During this process, the connecting rod and the rotating seat rotate relative to each other, thereby improving the stability of the device.
[0012] Furthermore, a limiting rod is provided at the end of the connecting rod away from the rotating seat and at the end of the rotating rod away from the rocker arm. The limiting rod passes through the connecting rod and the rotating rod and is rotatably connected to the connecting rod and the rotating rod. Both ends of the limiting rod are threaded with limiting nuts, and the sidewalls of the two limiting nuts abut against the sidewalls of the connecting rod and the rotating rod, respectively.
[0013] By adopting the above technical solution, when the connecting rod and the rotating rod rotate relative to each other, the limiting rod limits the connection rod and the rotating rod. During this process, the limiting rod reduces the probability of the connecting rod and the rotating rod separating from each other, thereby improving the stability of the device.
[0014] Furthermore, an annular groove is provided on the inner wall of the rotary table, and an annular block is rotatably disposed in the annular groove, the annular block being fixed to the worktable.
[0015] By adopting the above technical solution, when the worktable rotates, the annular block rotates under the action of the worktable. During this process, the annular block limits the worktable, thereby reducing the probability of the worktable moving up and down, and thus improving the stability of the device.
[0016] Furthermore, the inner wall of the mounting groove is provided with multiple vent holes.
[0017] By adopting the above technical solution, the vent hole reduces the probability that the metal can bottom will be sucked into the placement groove after the stamping is completed, thereby reducing the difficulty for workers to remove the metal can bottom and thus reducing the difficulty of the workers' work.
[0018] Furthermore, multiple heat dissipation holes are provided through the inner wall of the rotary table.
[0019] By adopting the above technical solution, the heat dissipation holes reduce the probability of the electric cylinder overheating and being damaged, thereby extending the service life of the device.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. In this application, when workers need to produce the bottom of a metal can, they must place a round piece into a placement slot. Then, the worker must activate the stamping cylinder, causing the piston rod of the cylinder to move downwards, thereby causing the bottom forming component installed at the end of the piston rod to stamp the round piece into a metal can bottom. After stamping is complete, the worker must control the worktable to rotate via a control device, aligning the other placement slots with the stamping cylinder. At this point, the worker can remove the stamped metal can from the placement slot. This process reduces the probability of worker injury and allows for the removal of the metal can bottom during stamping, thus improving worker efficiency.
[0022] 2. In this application, when the worker needs to rotate the worktable, the worker needs to activate the electric cylinder, which extends the piston rod of the electric cylinder, causing the connecting rod and the rotating rod to rotate. During this process, the connecting rod and the rotating rod rotate relative to each other. When the piston rod of the electric cylinder completes one extension and retraction, the rotating rod rotates 360 degrees under the action of the connecting rod (the specific working principle can be referred to the crank-slider mechanism). Subsequently, after the rotating rod rotates 360 degrees, the rocker arm rotates 360 degrees along the axis of rotation under the action of the rotating rod, which in turn causes the drive rod to rotate 360 degrees along the axis of rotation under the action of the rocker arm. This causes the connecting plate to rotate 90 degrees under the action of the drive rod, which in turn causes the connecting shaft to rotate 90 degrees under the action of the connecting plate. This causes the worktable to rotate 90 degrees under the action of the connecting shaft, thus aligning the placement slot with the piston rod of the stamping cylinder. At this time, the worker can remove the stamped metal can from the placement slot. In this process, the probability of worker injury is reduced, and the bottom of the metal can can also be removed during the stamping process, thereby improving the worker's work efficiency.
[0023] 3. In this application, when the electric cylinder piston rod extends and retracts, the rotating seat moves synchronously with the electric cylinder piston rod under the action of the electric cylinder piston rod. During this process, the connecting rod and the rotating seat rotate relative to each other, thereby improving the stability of the device. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-4 As shown in the embodiment of this application, a metal can bottom forming device is disclosed, including a mounting platform 1, a rotating platform 11, a worktable 12, a support frame 13, a stamping cylinder 14, a control component 2, a drive component 3, a rotating seat 4, a limiting rod 5, a limiting nut 51, and an annular block 61. The mounting platform 1 is a rectangular plate structure, and the rotating platform 11 is a cylindrical structure with an open top and a vertical axis. The rotating platform 11 is fixedly mounted on the upper surface of the mounting platform 1. The worktable 12 is a cylindrical structure, and its axis coincides with the axis of the rotating platform 11. The worktable 12 is rotatably mounted inside the rotating platform 11, and a plurality of mounting slots 15 are distributed in a circular array on the upper surface of the worktable 12. The support frame 13 has an L-shaped cross-section and is fixedly mounted on the upper surface of the mounting platform 1. The stamping cylinder 14 is fixedly mounted on the upper surface of the support frame 13 in the horizontal direction, and the axis of its output shaft is vertical. The piston rod end of the stamping cylinder 14 passes through the support frame 13. A can bottom forming part (not shown in the figure) is fixedly mounted on the end of the piston rod of the stamping cylinder 14, and is used to stamp the disc into a metal can bottom. The control device is located inside the rotary table 11 and is used to control the rotation of the worktable 12. The control device includes a control component 2 and a drive component 3.
[0031] When workers need to produce the bottom of a metal can, they must place a disc into the placement slot 15. Then, the worker activates the stamping cylinder 14, causing its piston rod to move downwards. This forces the bottom forming component, mounted at the end of the piston rod, to stamp the disc into the metal can bottom. After stamping, the worker controls the worktable 12 to rotate, aligning the other placement slots 15 with the stamping cylinder 14. At this point, the worker can remove the stamped metal can from the placement slot 15. This process reduces the risk of injury to workers and allows for the removal of the can bottom during stamping, thus improving work efficiency.
[0032] The control assembly 2 includes a connecting shaft 21, a connecting plate 22, a rocker arm 23, a drive rod 24, and a rotating shaft 25. The connecting shaft 21 is a cylindrical rod structure, its axis coinciding with the axis of the worktable 12, and is fixedly mounted on the bottom surface of the worktable 12. The connecting plate 22 is fixedly mounted on the bottom surface of the connecting shaft 21, its axis coinciding with the axis of the connecting shaft 21, and a plurality of drive grooves 26 are arranged in a circumferential array on its upper surface. The rocker arm 23 is rotatably mounted inside the rotary table 11. The drive rod 24 is a cylindrical rod structure with a vertical axis, and is fixedly mounted on the upper surface of the rocker arm 23, matching the drive grooves 26. The rotating shaft 25 is a cylindrical rod structure with a vertical axis, and is rotatably mounted on the upper surface of the rocker arm 23. The rotating shaft 25 is fixed to the inner wall of the rotary table 11 by a mounting component (not shown in the figure).
[0033] The drive assembly 3 includes an electric cylinder 31, a rotating rod 32, and a connecting rod 33. The electric cylinder 31 is fixedly mounted on the inner wall of the rotary table 11, and its piston rod axis is horizontal. The rotating rod 32 is fixedly mounted on the bottom surface of the rocker arm 23, and the connecting rod 33 is rotatably mounted at the end of the rotating rod 32 away from the rocker arm 23. The end of the connecting rod 33 away from the rotating rod 32 is rotatably connected to the piston rod of the electric cylinder 31.
[0034] When the operator needs to rotate the worktable 12, the operator needs to activate the electric cylinder 31, which extends the piston rod of the electric cylinder 31, causing the connecting rod 33 and the rotating rod 32 to rotate. During this process, the connecting rod 33 and the rotating rod 32 rotate relative to each other. When the piston rod of the electric cylinder 31 completes one extension and retraction, the rotating rod 32 rotates 360 degrees under the action of the connecting rod 33 (for specific working principles, please refer to the crank-slider mechanism). Subsequently, after the rotating rod 32 rotates 360 degrees, the rocker arm 23 rotates 360 degrees along the axis of the rotating shaft 25 under the action of the rotating rod 32, which in turn causes the drive rod 24 to rotate 360 degrees along the axis of the rotating shaft 25 under the action of the rocker arm 23. This causes the connecting plate 22 to rotate 90 degrees under the action of the drive rod 24, which in turn causes the connecting shaft 21 to rotate 90 degrees under the action of the connecting plate 22. This causes the worktable 12 to rotate 90 degrees under the action of the connecting shaft 21, thus aligning the mounting groove 15 with the piston rod of the stamping cylinder 14. At this point, the workers can remove the stamped metal can from the placement slot 15. This reduces the probability of injury to the workers and also allows them to remove the bottom of the metal can during the stamping process, thereby improving the workers' work efficiency.
[0035] The rotating seat 4 is fixedly mounted on the end of the piston rod of the electric cylinder 31, and the rotating seat 4 is rotatably connected to the end of the connecting rod 33 away from the rotating rod 32.
[0036] When the piston rod of the electric cylinder 31 extends and retracts, the rotating seat 4 moves synchronously with the piston rod of the electric cylinder 31 under the action of the piston rod. During this process, the connecting rod 33 and the rotating seat 4 rotate relative to each other, thereby improving the stability of the device.
[0037] The limiting rod 5 is a round rod structure with a vertical axis. It is positioned at the end of the connecting rod 33 furthest from the rotating seat 4 and at the end of the rotating rod 32 furthest from the rocker arm 23. The limiting rod 5 passes through the connecting rod 33 and the rotating rod 32 and is rotatably connected to both. Two limiting nuts 51 are provided and threadedly connected to both ends of the limiting rod 5. The sidewalls of the two limiting nuts 51 abut against the sidewalls of the connecting rod 33 and the rotating rod 32, respectively.
[0038] When the connecting rod 33 and the rotating rod 32 rotate relative to each other, the limiting rod 5 limits the connection rod 33 and the rotating rod 32. During this process, the limiting rod 5 reduces the probability of the connection rod 33 and the rotating rod 32 separating from each other, thereby improving the stability of the device.
[0039] An annular groove 6 is provided on the inner wall of the rotary table 11. An annular block 61 is rotatably disposed in the annular groove 6, and its axis coincides with the axis of the worktable 12. The annular block 61 and the worktable 12 are fixed to each other.
[0040] When the worktable 12 rotates, the annular block 61 rotates under the action of the worktable 12. During this process, the annular block 61 limits the worktable 12, thereby reducing the probability of the worktable 12 moving up and down, and thus improving the stability of the device.
[0041] To reduce the difficulty of the work for the workers, multiple vent holes 7 are provided through the inner wall of the placement groove 15. The vent holes 7 reduce the probability that the bottom of the metal can will be sucked into the placement groove 15 after the metal can is stamped, thereby reducing the difficulty for the workers to remove the bottom of the metal can and thus reducing the difficulty of the workers' work.
[0042] To extend the service life of the device, multiple heat dissipation holes 8 are provided through the inner wall of the rotary table 11. The heat dissipation holes 8 reduce the probability of the electric cylinder 31 overheating and being damaged, thereby extending the service life of the device.
[0043] The working principle of the metal can bottom forming device in this embodiment is as follows: When the worker needs to produce the metal can bottom, the worker needs to place the round piece into the placement groove 15. Then, the worker needs to start the stamping cylinder 14, which causes the piston rod of the stamping cylinder 14 to move downward, thereby causing the bottom forming part installed at the end of the piston rod of the stamping cylinder 14 to stamp the round piece into the metal can bottom. After the stamping is completed, the worker needs to control the worktable 12 to rotate through the control device, so that the other placement grooves 15 are aligned with the stamping cylinder 14. At this time, the worker can take out the stamped metal can from the placement groove 15. In this process, the probability of worker injury is reduced, and the metal can bottom can be removed during the stamping process, thereby improving the worker's work efficiency.
[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
