[0034] Reference Figures 1-3 The present invention provides an embodiment of a CNC metal shearing machine, comprising a shearing device 1, which is a CNC shearing machine used for shearing metal sheets.

The middle part of the fixed frame 21 is rotatably connected to the feeding roller 25, and its top surface height is the same as the top surface of the bottom rod 32 and the top surface of the feeding plate 342. The right end of the feeding roller 25 is fixedly connected to a second motor 26 through a coupling, which is used to drive the feeding roller 25 to rotate.

[0036] like Figures 4-5 As shown, the feeding mechanism 4 includes a mounting frame 41 for connecting various components. A drive assembly 42 is located in the middle of the mounting frame 41, which drives the feeding assembly 43 to reciprocate back and forth for feeding. The feeding assembly 43 is located at the front of the drive assembly 42 for pushing the sheet material. A limiting ring 44 is fixed to the right side of the mounting frame 41 to restrict the movement of the push rod 425, allowing it to move only back and forth. The drive assembly 42 includes a primary motor 421 for powering the feed mechanism. The component provides power. The first motor 421 is fixedly connected to the mounting bracket 41. The output end of the first motor 421 is fixedly connected to the rotating shaft 422 through the coupling, which is used to drive the support plate 423.

A push block 432 is slidably connected through the middle of the housing 431, which is used to push the plate material. Two limit rods 433 are fixedly connected to the bottom of the push block 432, which are used to limit the movement direction of the push block 432 to a certain extent. The limit rods 433 are slidably connected through the housing 431.

[0038] Please see Figures 6-7The placement mechanism 3 includes a bracket 31, which is used to connect various components. A bottom rod 32 is fixedly connected to the middle of the bracket 31, and its top surface height is the same as that of the bracket 31. An adjustment component 33 is provided in the middle of the bottom rod 32, which is used to adjust the distance between the two feeding components 34. Feeding components 34 are provided on both the left and right sides of the top surface of the adjustment component 33, which are used to place materials. The two feeding components 34 are symmetrically arranged. A sliding opening 321 is opened at the rear of the bottom rod 32, which is used to connect with the pushing component 43. The push rod 425 passes through and is movably connected to the bracket 31 and the bottom rod 32. The outer shell 431 is slidably connected to the sliding opening 321.

[0039] Furthermore, the adjusting assembly 33 includes two guide frames 331 for connecting various components. The two guide frames 331 are fixedly connected to the base rod 32 and the support 31. An adjusting rod 332 is rotatably connected through the two guide frames 331, and its exterior is provided with threads in opposite directions. The adjusting rod 332 is rotatably connected through the support 31 and the base rod 32. A slider 333 is slidably connected inside the guide frame 331 for adjusting the position of the feeding assembly 34. The adjusting rod 332 and the slider 333 are threadedly connected through each other. The feeding assembly 34 includes a connecting frame 341 for connecting various components. The connecting frame 341 is located near the base rod 32. A feeding plate 342 is fixedly connected to one side of 2, which is used to place the sheet material. The connecting frame 341 is fixedly connected to the slider 333 and slidably connected to the bracket 31. A control rod 343 is rotatably connected through the middle of the connecting frame 341. The outer wall of the control rod 343 is provided with threads in opposite directions. The front and rear parts of the inner wall of the connecting frame 341 are slidably connected to the connecting blocks 344, which are used to connect the positioning rod 345. The control rod 343 and the connecting block 344 are threadedly connected through the control rod 343. The top of the connecting block 344 is fixedly connected to the positioning rod 345, which is used to position the sheet material. A certain gap is left between the lower part of the block and the feeding plate 342 to facilitate feeding.

[0040] Working principle: First, adjust the adjusting rod 332 according to the size of the sheet material, causing it to move the two sliders 333 closer or further apart. This, in turn, moves the two feeding components 34 connected to the upper part of the sliders 333 to adjust their positions. Then, adjust the control rod 343 according to the size of the sheet material. The control rod 343 will then move the two connecting blocks 344 connected to it closer or further apart, thereby adjusting the distance between the two positioning rods 345. Once the positions of the four positioning rods 345 are properly adjusted, the sheet material is immediately placed on the support 31. At this time, the sheet material will rest on the feeding plate 342 and the bottom. The top surface of rod 32 is then adjusted, and the screw 434 is rotated according to the thickness of the sheet material. This causes the screw 434 to drive the push block 432 to move up and down, thereby adjusting the extension height of the push block 432 so that the feeding assembly 34 can only push out one sheet material each time it pushes out. Then, according to the thickness of the sheet material, the electric rod 22 is activated, which adjusts the distance between the auxiliary roller 24 and the feeding roller 25 through the outer frame 23, so that only one sheet material can pass between the auxiliary roller 24 and the feeding roller 25. After the feeding assembly 34 and the feeding assembly 2 are adjusted, the feeding assembly 2 and the pushing mechanism 4 of the shearing equipment 1 can be activated.

[0041] When the feeding mechanism 4 is activated, motor 421 will drive the support plate 423 connected to it to rotate via shaft 422. When the support plate 423 rotates, the connecting rod 424 connected to one end of the support plate 423 will be driven to move accordingly. Since the other end of the connecting rod 424 is connected to the push rod 425, and the push rod 425 is connected to the limit ring 44, when the support plate 423 rotates, it will drive the push rod 425 to move back and forth through the connecting rod 424. When the push rod 425 moves, the feeding assembly 43 connected to the push rod 425 through the housing 431 will be driven accordingly. Moving back and forth, when the pushing component 43 is pushed forward, the pushing block 432 will push a piece of board material on the bottom rod 32 towards the upward feeding component 2. After the bottom piece of board material is conveyed to the shearing equipment 1 by the feeding component 2, the push rod 425 will drive the pushing component 43 to reset backward. At this time, the board material located above the board material will fall to the top surface of the bottom rod 32. As the push rod 425 pushes the pushing component 43 forward again, the pushing component 43 will push the board material to move towards the upward feeding component 2. This process is repeated to complete the automatic feeding of the board material.

[0042] When the feeding assembly 2 is turned on, the second motor 26 will drive the feeding roller 25 to rotate, so that the feeding roller 25 can push the pushing assembly 43 to the space between the auxiliary roller 24 and the feeding roller 25 and transport the board material to the shearing equipment 1 for shearing operation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
