Specific embodiments

[0031] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The present utility model can be implemented in the following manner:

[0032] Embodiment 1

[0033] Referring to Figures 1-3 , the automatic metal disc cutting machine includes a frame 1, a material pressing device 2 and a cutting device 3.

[0034] Among them, a cutting table 11 is provided on the frame 1, and a controller 6 is provided on the side of the frame 1. There is a control switch on the controller 6 to control the operation of the material pressing device 2 and the cutting device 3.

[0035] The described blank holding device 2 is arranged on the cutting table 11, and the blank holding device 2 is connected with a rotation driving source 4 that drives the metal sheet 7 on the blank holding device 2 to rotate. Specifically, the blank holding device 2 includes a bridge support 21, an upper clamping plate 22, and a lower clamping plate 23 arranged below the upper clamping plate 22. The bridge support 21 is arranged on the cutting table 11. The bridge support 21 is arranged on the diagonal line of the cutting table 11 to maximize its length, enabling a larger-area metal sheet 7 to be placed. The upper clamping plate 22 is movably installed on the bridge support 21, and a lifting driving source for controlling the lifting of the upper clamping plate 22 is arranged at the top of the upper clamping plate 22; the lifting driving source includes a first air cylinder 24 and a first connecting rod 25. One end of the first connecting rod 25 is connected with the first air cylinder 24, and the other end is connected with the upper clamping plate 22. The first air cylinder 24 drives the upper clamping plate 22 to lift through the first connecting rod 25, thereby adjusting the distance between the upper clamping plate 22 and the lower clamping plate 23, and further achieving the purpose of clamping or loosening the metal sheet 7.

[0036] The bottom of the lower clamping plate 23 is movably arranged on the cutting table 11 through a rotation connection assembly 26 and is movably connected with the rotation driving source 4. The rotation connection assembly 26 includes a bearing seat 261 arranged on the cutting table 11 and a rotating rod 262 movably connected with the bearing seat 261. The rotating rod 262 is rotationally connected with the bearing seat 261 through a bearing, that is, the rotating rod 262 can rotate within the bearing seat 261. One end of the rotating rod 262 is fixedly connected to the center of the bottom of the lower clamping plate 23, and the other end is movably connected with the rotation driving source 4. The rotation driving source 4 is arranged within the frame 1. The rotation driving source 4 includes a rotation motor 41. The rotation motor 41 is movably connected with the rotating rod 262 of the blank holding device 2 through a transmission belt 42. During the cutting process, the position of the cutting device 3 remains fixed. The rotation motor 41 drives the transmission belt 42 to rotate, and the transmission belt 42 drives the lower clamping plate 23 to rotate through the rotating rod 262, thereby driving the metal sheet 7 to rotate.

[0037] Anti-scratch cloths (not marked in the figure) for preventing scratching of the metal sheet 7 are sleeved on the upper clamping plate 22 and the lower clamping plate 23. Since the metal sheet 7 will be subjected to great pressure and friction during the cutting process, the anti-scratch cloths can greatly reduce the risk of the metal sheet 7 being scratched or deformed.

[0038] The described cutting device 3 is arranged on the side of the material pressing device 2, and the cutting device 3 is connected with a pushing device 5 that drives the cutting device 3 to reciprocate in the radial direction of the metal plate 7. The cutting device 3 includes a movable tool holder 31, a tool clamp 32 installed on the movable tool holder 31, and a tool clamp driving source 33 that drives the tool clamp 32 to move up and down. The tool clamp 32 includes an upper blade 321 and a lower blade 322, and the upper blade 321 is connected with the tool clamp driving source 33. The tool clamp driving source 33 drives the upper blade 321 to move up and down. The tool clamp driving source 33 includes a second air cylinder 331 and a second connecting rod 332. One end of the second connecting rod 332 is connected with the second air cylinder 331, and the other end is connected with the upper blade 321. The second air cylinder 331 can adjust the distance between the upper blade 321 and the lower blade 322 through the second connecting rod 332 to adapt to metal plates 7 of different thicknesses. In this embodiment, by means of the moving upper blade 321 and the fixed lower blade 322, with a reasonable blade gap, a shearing force is applied to metal plates 7 of various thicknesses, so that the metal plates 7 are broken and separated according to the required dimensions.

[0039] The described pushing device 5 includes a guide rail 51 arranged below the movable tool holder 31 and a tool holder driving source 52 that drives the movable tool holder 31 to reciprocate along the guide rail 51. The movable tool holder 31 is slidably connected with the guide rail 51. The tool holder driving source 52 includes a tool holder air cylinder 521 and a push rod 522. One end of the push rod 522 is connected with the tool holder air cylinder 521, and the other end is connected with the movable tool holder 31. The tool holder air cylinder 521 drives the movable tool holder 31 to reciprocate on the guide rail 51 through the push rod 522, thereby adjusting the distance between the tool clamp 32 and the center of the metal plate 7, and further realizing cutting the metal plate 7 into metal discs with different diameters.

[0040] Embodiment 2

[0041] The specific structure of this Embodiment 2 is basically the same as that of Embodiment 1, and the difference lies in that, referring to Figure 4 , the tool holder driving source 52 includes a tool holder motor and a ball screw 524 arranged in the guide rail 51. One end of the ball screw 524 is connected with the tool holder motor 523, and the other end is connected with one end of the guide rail 51 far away from the tool holder motor 523; a slider 525 movably connected with the ball screw 524 is arranged below the movable tool holder 31. The principle that the ball screw converts the rotary motion into the linear motion of the slider is common knowledge and will not be elaborated here. The tool holder motor 523 drives the ball screw 524 to rotate, and the ball screw 524 drives the movable tool holder 31 to reciprocate through the slider, thereby adjusting the distance between the tool clamp 32 and the center of the metal plate 7. Using the ball screw 524 to adjust the distance has higher accuracy.

[0042] Working principle: First, determine the radius of the required metal disc. The movable tool holder 31 is driven by the tool holder driving source 52 to move on the guide rail 51, so that the distance between the tool clamp 32 and the center of the metal sheet 7 is the same as the radius of the metal disc. Then, the first cylinder 24 drives the upper clamping plate 22 to rise through the first connecting rod 25, adjusts the distance between the upper clamping plate 22 and the lower clamping plate 23, and then places the metal sheet 7 between the upper clamping plate 22 and the lower clamping plate 23. The first cylinder 24 drives the upper clamping plate 22 to descend through the first connecting rod 25 to clamp the metal sheet 7. The cutting device 3 and the rotation driving source 4 are started. The rotation motor 41 drives the transmission belt 42 to rotate, and the transmission belt 42 drives the lower clamping plate 23 to rotate through the rotating rod 262, thereby driving the metal sheet 7 to rotate until the metal sheet 7 is cut into metal discs. Finally, the first cylinder 24 drives the upper clamping plate 22 to rise through the first connecting rod 25 to release the metal disc.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
