It should be noted that, when the initial position of the sheave 64 in this embodiment is 10-30 ° from the initial position, the outer cylinder 51 may be driven to rotate 30 ° by the driving wheel 61, and when the sheave 64 rotates one turn, the outer cylinder 51 remains stationary all the time, and the cam plate 67 rotates one turn and drives the pressing rod 541 to reciprocate once. That is, the cam plate 67 drives the pressing rod 541 to reciprocate once while the outer cylinder 51 is kept stationary.
Specifically, when the aluminum plate to be punched placed on the lower pressure bearing die 42 needs to be punched, the operator can control the driving mechanism 62 to drive the first bevel gear 63 and the grooved pulley 64 to rotate synchronously, the rotating grooved pulley 64 drives the outer cylinder 51 to rotate for 30 ° through the driving wheel 61, the outer cylinder 51 at this time is kept still, and a group (a row) of positioning through holes 501 on the outer cylinder 51 are located right above the blanking hole 401. In the process of rotating the outer cylinder 51, the outer cylinder 51 drives the aluminum plate to be punched to move a certain distance by virtue of friction force.
Meanwhile, the first bevel gear 63 drives the transmission shaft 65 to rotate through the second bevel gear 66, the rotating transmission shaft 65 drives the cam disc 67 to rotate through the belt transmission mechanism 68, the rotating cam disc 67 applies a pressing force to the first roller 542 after the outer cylinder 51 rotates by 30 degrees, the first roller 542 is forced to push the pressing rod 541 to drive the plurality of driving blocks 543 and the baffle 544 to move, the moving baffle 544 compresses the second spring 545, the moving driving blocks 543 apply downward pressure to the second roller 552 in the lowermost group of transmission mechanisms 55, the second roller 552 is pressed to push the supporting plate 531 to move downwards through the transmission rod 551, the moving supporting plate 531 compresses the first spring 533 and drives the plurality of columnar cutting dies 532 to stretch out from the corresponding positioning through holes 501 and punch the aluminum plate to be punched until the columnar cutting dies 532 stretch into the corresponding blanking holes 401, and accordingly punched hole-shaped waste materials of the aluminum plate to be punched are discharged from the blanking holes 401.
After the aluminum plate to be punched is punched with a row of through holes, along with the rotation of the cam disc 67, the pressing rod 541 gradually loses the pressure applied by the cam disc 67, and under the reverse acting force of the second spring 545, the pressing rod 541 drives the plurality of driving blocks 543 to reset, and meanwhile, the supporting plate 531 drives the plurality of columnar cutting dies 532 to reset under the reverse acting force of the first spring 533.
When the rotating grooved wheel 64 drives the outer cylinder 51 to continue to rotate for 30 degrees through driving the driving wheel 61, the rotating outer cylinder 51 will continue to drive the aluminum plate to be punched to move, and the moving aluminum plate to be punched continues to be punched through the columnar cutting die 532, and the above steps are repeated repeatedly until the whole aluminum plate to be punched is punched with multiple rows of regular through holes.
It can be appreciated that by pushing the columnar cutting die 532 out for punching the aluminum plate, the columnar cutting die 532 is not limited by the length, and thus the columnar cutting die 532 can punch aluminum plates with different thicknesses by adjusting the height of the outer cylinder 51. And when the outer cylinder 51 rotates, the deformation of the punching shape caused by the long columnar cutting die when the thick aluminum plate is punched does not occur.
In sum, the aluminum plate punching equipment provided by the embodiment of the application not only can realize punching of multiple rows of regular through holes on the aluminum plate, but also can effectively improve the application range of punching on aluminum plates with different thicknesses, and effectively avoid the distortion of the punching shape, thereby being beneficial to improving the punching precision and consistency of the aluminum plate, and simultaneously being capable of effectively ensuring the stable and reliable product quality.
