Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a fine-tuning blanking device and a punching machine. Background Art

[0002] A punching machine is a device for punching sheet materials, used to punch the sheet materials into a predetermined shape. In the traditional technology, the blanking device of the punching machine generally consists of a fixed die, a movable die and a driving mechanism. The driving mechanism drives the movable die to approach the fixed die, so that the movable die and the fixed die are closed to punch the sheet material between the fixed die and the movable die, realizing punching the sheet material into a predetermined shape. However, the stroke of the driving mechanism for reciprocally driving the movable die is fixed, that is, the closing distance between the movable die and the fixed die is fixed. For a sheet material with a thickness greater than the closing distance, the movable die and the fixed die are likely to extrude the sheet material, thereby increasing the blanking loss of the sheet material. For a sheet material with a thickness less than the closing distance, the sheet material is likely to shake between the movable die and the fixed die, thereby reducing the blanking precision of the sheet material. There is a technical problem that due to the fixed closing distance, the processing range of the thickness of the sheet material by the blanking device is limited. Summary of the Utility Model

[0035] Below, in combination with Figures 1 to 3 , the above-mentioned fine-tuning blanking device 100 will be further described.

[0036] As Figures 1 to 2As shown, the base frame 10 includes a frame body 11 and a guide rail 12, and the guide rail 12 is installed on the frame body 11.

The inner wall of the adjustment hole is provided with an internal thread (not shown in the figure). The adjustment rod 53 passes through the adjustment hole and is rotatably connected to the slide 41 of the actuating mechanism 40, and is provided with an external thread (not shown in the figure) that matches the internal thread. The fine-tuning drive assembly 54 is installed on the fixed platform 51 and drives the adjustment rod 53 to rotate in the adjustment hole.

[0038] Among them, Figure 3 As shown, there are multiple adjustment seats 52 and adjustment rods 53, and the fine-tuning drive assembly 54 drives each adjustment rod 53 to rotate synchronously to improve the control accuracy of the slide 41. Further, the fine-tuning drive assembly 54 includes a fine-tuning drive member 541 and a transmission belt 542.

Further, the fine-tuning drive assembly 54 also includes an adjustment plate 543 and a tensioning wheel 544. The adjustment plate 543 is installed on the fixed platform 51, and the tensioning wheel 544 is rotatably installed on the adjustment plate 543 and abuts against the transmission belt 542, so that the transmission belt 542 always maintains a transmission connection with each adjustment rod 53.

[0039] like Figure 3 As shown, the adjustment mechanism 50 also includes a transfer rod 55 and a limit plate 56 . The transfer rod 55 passes through the fixed platform 51 and is connected to the actuating mechanism 40 .

[0040] Furthermore, ifFigure 3 As shown, the adjusting mechanism 50 further includes a buffer member 57.

The airbag 572 is connected to the connecting plate 571 and is disposed between the connecting plate 571 and the fixed platform 51, or between the connecting plate 571 and the limiting plate 56.

[0041] The working principle of the fine-tuning blanking device 100 of the present utility model is as follows: According to the thickness of the sheet material to be processed, in combination with the distance that the moving die 30 is controlled to move by the actuating mechanism 40, calculate the distance of the actuating mechanism 40 relative to the fixed platform 51 of the adjusting mechanism 50. Drive the adjusting rod 53 to rotate in the adjusting seat 52 through the fine-tuning drive assembly 54 of the adjusting mechanism 50 to control the distance of the actuating mechanism 40 relative to the fixed platform 51, so that the distance when the fixed die 20 and the moving die 30 are closed is matched with the thickness of the sheet material, so as to realize blanking of sheet materials with different thicknesses.

[0042] The beneficial effect of the fine-tuning blanking device 100 of the present utility model is that: the moving die 30 and the actuating mechanism 40 are both slidably connected to the chassis 10. The adjusting mechanism 50 drives the adjusting rod 53 to rotate in the adjusting seat 52 through the fine-tuning drive assembly 54 to control the distance of the actuating mechanism 40 relative to the fixed platform 51. In this way, the distance when the fixed die 20 and the moving die 30 are closed can be accurately controlled, so as to achieve the purpose of increasing the processing range of the thickness of the sheet material by the blanking device.

[0043] As Figure 4 shown, it is a punching machine 200 shown in the present utility model. The punching machine 200 includes the fine-tuning blanking device 100 of any one of the above. By adopting the fine-tuning blanking device 100, it is beneficial to realize the processing of sheet materials with different thicknesses, so as to achieve the purpose of increasing the processing range of the punching machine 200.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
