[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0045] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0046] In one embodiment of this utility model, such as Figures 1-5 As shown, a metal can body forming and fastening device is provided, including an upper frame 10, a mold core mechanism 20, a pressing mechanism 30, and a pressing mechanism 40. The bottom of the upper frame 10 is divided into a pressing station and a pressing station (e.g., ...). Figure 5(The left side is the pressing station, and the right side is the pressing station). The mold core mechanism 20 includes a strip mold core 21 for supporting the can body metal sheet 100. The strip mold core 21 is located below the upper frame 10 and is arranged along the direction from the pressing station to the pressing station. The pressing mechanism 30 includes a first side hinge mold 31 and a second side hinge mold 32. Both the first side hinge mold 31 and the second side hinge mold 32 are rotatably connected to the pressing station of the upper frame 10 and distributed on both sides of the upper frame 10. The first side hinge mold 31 and the second side hinge mold 32 can... The compression mechanism 40 includes an upper compression mold 41 and a lower compression mold 42 that cooperates with the upper compression mold 41. The upper compression mold 41 is installed on the compression station of the upper frame 10, and the lower compression mold 42 is located below the compression station. It can cooperate with the upper compression mold 41 to cover the can body metal sheet 100 located on the strip mold 21 and preliminarily compressed at the compression position.

[0047] The working principle of the metal can body forming and fastening device provided in this embodiment of the present invention is explained below: When the metal sheet 100 of the can body is transferred above the strip mold core 21, the metal sheet is first located at the pressing station at the bottom of the upper frame 10. At this time, the strip mold core 21 can be raised to a certain height by the mechanism, and then the first side hinge mold 31 and the second side hinge mold 32 of the pressing mechanism 30 can be closed. After the first side hinge mold 31 and the second side hinge mold 32 are closed, the metal sheet 100 of the can body is wrapped. Covering the strip mold core 21, the hooks 101 at both ends of the can body metal sheet 100 are initially engaged. Then, the first side hinge mold 31 and the second side hinge mold 32 are opened, and the strip mold core 21 descends a certain height to continue conveying the initially engaged can body metal sheet 100 to the pressing station. At this time, the lower pressing can body mold 42 and the upper pressing can body mold 41 of the pressing mechanism 40 are closed to achieve pressing of the can body metal sheet 100 at the engagement position, completing the can body forming and fastening process. The metal can body forming and fastening device of this utility model can quickly bend the can body metal sheet 100 at the pressing station to engage the hooks 101, and press the engagement connection position at the hook 101 position at the pressing station, achieving higher production efficiency and better production quality.

[0048] It should be further stated that when the core mechanism 20, the pressing mechanism 30 and the pressing mechanism 40 perform their actions, they can be controlled by a single mechanism in a coordinated manner, or they can be controlled separately by multiple mechanisms in a coordinated manner.

[0049] In another embodiment of this utility model, such as Figures 5-6As shown, the mold core mechanism 20 further includes a mold core support plate 22, a horizontal connecting plate 23, and a mold core cam 24. The mold core support plate 22 is arranged vertically and its upper end is connected to one end of the strip mold core 21. The horizontal connecting plate 23 is connected to the lower side of the mold core support plate 22. A mold core bearing 231 is provided at the end of the horizontal connecting plate 23. A mold core curved groove 241 is provided on the inner side of the mold core cam 24. The mold core bearing 231 is accommodated and abuts against the groove wall of the mold core curved groove 241. When the mold core bearing 231 rotates along the mold core curved groove 241, it can drive the strip mold core 21 to intermittently rise and fall through the horizontal connecting plate 23 and the mold core support plate 22. Specifically, because the inner side of the mold core cam 24 has a curved groove 241, when the mold core bearing 231 rotates relative to the curved groove 241, the mold core bearing 231 will intermittently be in different high and low positions. At this time, it can drive the horizontal connecting plate 23 and the mold core support plate 22 connected to the horizontal connecting plate 23 to change their high and low positions. Since the strip mold core 21 is connected to the mold core support plate 22, it can also drive the strip mold core 21 to intermittently rise and fall. Thus, when the strip core 21 descends, it creates space for the can body metal sheet 100 to enter. When the strip core 21 rises, it can be positioned at a suitable height to wait for the first side hinge mold 31 and the second side hinge mold 32 to close and cover the can body metal sheet 100 outside the strip core 21, achieving the initial engagement of the hooks 101 at both ends of the can body metal sheet 100. Then, after the strip core 21 descends, it creates space again to transport the can body metal sheet 100 with the hooks 101 engaged to the pressing station.

[0050] In another embodiment of this utility model, such as Figure 6 As shown, the mold core mechanism 20 also includes a mold core linear slide rail 25, which is vertically arranged and connected to the side of the mold core support plate 22 to guide the mold core support plate 22 to rise and fall. Specifically, the guidance of the mold core linear slide rail 25 ensures that the mold core support plate 22 is more stable and does not deviate when rising and falling.

[0051] In another embodiment of this utility model, such as Figures 7-8As shown, the pressing mechanism 30 further includes a first side support plate 33, a first side cam 34, a first side connecting rod assembly 35, a second side support plate 36, a second side cam 37, and a second side connecting rod assembly 38. The first side support plate 33 and the second side support plate 36 are both vertically arranged and located below the first side hinge mold 31 and the second side hinge mold 32, respectively. The upper end of the first side support plate 33 is connected to the first side hinge mold 31 via the first side connecting rod assembly 35, and the upper end of the second side support plate 36 is connected to the second side hinge mold 32 via the second side connecting rod assembly 38. A first side bearing 331 is provided at the lower end of the first side support plate 33, and a first side curved groove is provided on the inner side of the first side cam 34. The first side bearing 331 is accommodated and abuts against the groove wall of the first side curved groove 341. The second side cam 37 is provided with a second side curved groove 371 on its inner side. The second side bearing 361 is accommodated and abuts against the groove wall of the second side curved groove 371. When the first side bearing 331 rotates along the first side curved groove 341, it can drive the first side hinge mold 31 to swing relative to the upper frame 10 through the first side support plate 33 and the first side connecting rod group 35. When the second side bearing 361 rotates along the second side curved groove 371, it can drive the second side hinge mold 32 to swing relative to the upper frame 10 through the second side support plate 36 and the second side connecting rod group 38. Specifically, the first side support plate 33, the first side cam 34, and the first side connecting rod group 35 are components that jointly control the first side hinge mold 31, and the second side support plate 36, the second side cam 37, and the second side connecting rod group 38 are components that jointly control the first side hinge mold 31. The two parts are distributed on both sides in a symmetrical or approximately symmetrical arrangement. When the bearing of the first side cam 34 rotates relative to the first side curved groove 341, it can cause the first side cam 34 to intermittently rise and fall. Similarly, the second side cam 37 can do the same. This can drive the first side support plate 33 and the second support plate to intermittently rise and fall. Through the intermittent rising and falling of the first side support plate 33 and the second side support plate 36, the first side connecting rod group 35 and the second side connecting rod group 38 can drive the first side hinge mold 31 and the second side hinge mold 32 to swing angle, thereby controlling the first side hinge mold 31 and the second side hinge mold 32 to close or open, so as to achieve the fastening of the hook 101 of the can body metal sheet 100.

[0052] In another embodiment of this utility model, such as Figures 7-8As shown, the core mechanism 20 further includes a first side linear slide rail 39 and a second side linear slide rail 39a. The first side linear slide rail 39 is vertically arranged and connected to the side of the first side support plate 33 to guide the first side support plate 33 to rise and fall. The second side linear slide rail 39a is vertically arranged and connected to the side of the second side support plate 36 to guide the second side support plate 36 to rise and fall. Specifically, the guidance of the first side linear slide rail 39 and the second side linear slide rail 39a ensures that the first side support plate 33 and the second side support plate 36 are more stable and do not deviate during rising and falling.

[0053] In another embodiment of this utility model, such as Figures 7-8 As shown, the first side linkage group 35 includes a first positive and negative threaded linkage 351, a first swing arm 352, a first fixed-distance linkage 353, and a first hinged linkage 354. The two ends of the first positive and negative threaded linkage 351 are respectively connected to the upper end of the first side support plate 33 and the lower end of the first swing arm 352 through rod end bearings. The first swing arm 352 is inclined and can swing. The first fixed-distance linkage 353 is arranged vertically and its upper and lower ends are respectively hinged to the upper end of the first swing arm 352 and the upper end of the first hinged linkage 354. The lower end of the first hinged linkage 354 is hinged to one side of the pressing station of the upper frame 10. The first side hinge mold 31 is fixedly connected to the side of the first hinged linkage 354. Specifically, the upper and lower ends of the first positive and negative toothed connecting rod 351 are respectively connected to rod end bearings. The first side support plate 33 and the first swing arm 352 are respectively connected through the two rod end bearings. Preferably, the first swing arm 352 is arranged at an angle, and its upper end is connected to the upper end of the first fixed distance connecting rod 353. The first fixed distance connecting rod 353 is preferably arranged vertically, and its lower end is connected to the first hinge-type connecting rod 354. The first hinge-type connecting rod 354 is hinged on the upper frame 10. The first side hinge mold 31 is fixedly connected to the side of the first hinge-type connecting rod 354. Thus, the lifting and lowering of the first side support plate 33 pulls the first swing arm 352 to swing, thereby driving the first fixed distance connecting rod 353 to lift and lower. When the first fixed distance connecting rod 353 lifts and lowers, it drives the first hinge-type connecting rod 354 to swing around the hinge point with the upper frame 10 as the axis. This controls the swing angle of the first side hinge mold 31, so that it can cooperate with the second side hinge mold 32.

[0054] In another embodiment of this utility model, such as Figures 7-8As shown, the first side linkage group 35 includes a second positive and negative threaded linkage 381, a second swing arm 382, ​​a second fixed-distance linkage 383, and a second hinged linkage 384. The two ends of the second positive and negative threaded linkage 381 are respectively connected to the upper end of the second side support plate 36 and the lower end of the second swing arm 382 through rod end bearings. The second swing arm 382 is inclined and can swing. The second fixed-distance linkage 383 is arranged vertically and its upper and lower ends are respectively hinged to the upper end of the second swing arm 382 and the upper end of the second hinged linkage 384. The lower end of the second hinged linkage 384 is hinged to the other side of the pressing station of the upper frame 10. The second side hinge mold 32 is fixedly connected to the side of the second hinged linkage 384. Specifically, the upper and lower ends of the second positive and negative toothed connecting rod 381 are respectively connected to rod end bearings. The second side support plate 36 and the second swing arm 382 are respectively connected through the two rod end bearings. Preferably, the second swing arm 382 is arranged at an angle, and its upper end is connected to the upper end of the second fixed distance connecting rod 383. The second fixed distance connecting rod 383 is preferably arranged vertically, and its lower end is connected to the second hinge-type connecting rod 384. The second hinge-type connecting rod 384 is hinged to the upper frame 10. The second side hinge mold 32 is fixedly connected to the side of the second hinge-type connecting rod 384. Thus, the second swing arm 382 is swung by the lifting and lowering of the second side support plate 36, thereby driving the second fixed distance connecting rod 383 to rise and fall. When the second fixed distance connecting rod 383 rises and falls, it drives the second hinge-type connecting rod 384 to swing around the hinge point with the upper frame 10 as the axis. This controls the swing angle of the second side hinge mold 32, so that it can cooperate with the first side hinge mold 31.

[0055] In another embodiment of this utility model, such as Figure 9As shown, the bone pressing mechanism 40 also includes a lower mold support plate 43 and a lower mold cam 44. The lower mold support plate 43 is arranged vertically. The lower bone pressing mold 42 is installed on the upper end of the lower mold support plate 43. A lower mold bearing 431 is provided at the lower end of the lower mold support plate 43. A lower mold curved groove 441 is provided on the inner side of the lower mold cam 44. The lower mold bearing 431 accommodates and abuts against the groove wall of the lower mold curved groove 441. When the lower mold bearing 431 rotates along the lower mold curved groove 441, the lower mold support plate 43 can drive the lower bone pressing mold 42 to rise and fall intermittently. Specifically, because the lower mold cam 44 has a curved groove 441 on its inner side, when the lower mold bearing 431 rotates relative to the curved groove 441, the lower mold bearing 431 will intermittently be in different high and low positions. At this time, the lower mold support plate 43 can be driven to change its high and low position. Since the lower pressure bone can body mold 42 is connected to the lower mold support plate 43, the lower pressure bone can body mold 42 can be driven to rise and fall intermittently. Thus, when the lower pressure bone can body mold 42 rises, it can cooperate with the upper pressure bone can body mold 41 located above to press the bone position of the can body metal piece 100 at the snap-fit ​​position after the initial hook 101 is snapped, ensuring the stability and reliability of the snap-fit ​​connection of the hook 101.

[0056] In another embodiment of this utility model, such as Figure 9 As shown, the bone-pressing mechanism 40 also includes a lower mold linear slide rail 45, which is vertically arranged and connected to the side of the lower mold support plate 43 to guide the lower mold support plate 43 to rise and fall. Specifically, the lower mold linear slide rail 45 ensures that the lower mold support plate 43 is more stable and does not deviate when rising and falling.

[0057] In another embodiment of this utility model, such as Figures 2-4As shown, the metal can body forming and fastening device further includes a linkage mechanism 50, which includes a main shaft 51. The main shaft 51 is sequentially connected to the first side cam 34, the mold core cam 24, the lower mold cam 44, and the second side cam 37. The first side cam 34, the mold core cam 24, the lower mold cam 44, and the second side cam 37 are all connected and fixed to the main shaft 51.
