Firstly, the material 9 to be punched is placed on a discharging platform 29, the material is fixed by a front fixing mechanism 26 and a rear fixing mechanism 25, a left fixing mechanism 27 and a right fixing mechanism 28 can be adopted for fixing when necessary, a driving motor 24 drives a screw rod 23 to rotate, a sliding table 22 moves towards a main body driving mechanism 31 along a sliding rail 21, when the material 9 to be punched moves below the main body driving mechanism 31, the main body driving mechanism 31 acts to drive a die conveying device 5 to move downwards, a punching die 6 is driven to move downwards, and a cutter 609 can contact the material 9 to be punched and punch.
After punching, the lower end of the main body driving mechanism 31 moves upwards to drive the die conveying device 5 to move upwards, and in the process of moving the die conveying device 5 upwards, the second driving mechanism 52 drives the two sets of punching dies to move leftwards simultaneously. In the process, waste remains in the cavity of the cutter 609 and product remains below the blanking plate 607. At this time, the state of the punching die is still as shown in fig. 7, that is, the blanking plate 607 is still in close contact with the mounting plate 605. Meanwhile, the motor in the feeding device 2 is driven in a reverse direction to drive the screw rod 23 to rotate in a reverse direction, and the sliding table 22 is withdrawn below the main body driving mechanism 31.
When the left punching die moves below the left blanking mechanism 41 and the right die moves below the main body driving mechanism 31, the left blanking mechanism 41 starts to perform blanking operation, that is, the lower part of the blanking cylinder 44 moves downwards to drive the blanking die plate 43 to move downwards, the blanking probe 46 and the ejector rod 45 move downwards, and the blanking probe 46 enters the stepped hole 602 first and ejects the waste in the cavity of the cutter 609, and the waste falls into the left waste collection box 71 below the left blanking mechanism 41 to finish the action of removing the waste. Then, the ejector rod 45 touches the baffle 611 at the top of the connecting column 610 and continuously presses the connecting column 610 downwards to drive the blanking plate 607 to move downwards, the punched product is ejected out, and the blanking action is completed, as shown in fig. 12.
After the product is ejected, the ejector rod 45 moves upwards, the connecting column 610 gradually moves upwards under the action of the elastic element 612 and returns to the initial state, and the blanking plate 607 also gradually moves upwards to be attached to the mounting plate 605.
The left blanking mechanism 41 performs blanking, and at the same time, the placement feeder 2 relocates the material 9 to be die-cut and conveys it to the lower side of the main body driving mechanism 31, and thereafter, performs the die-cutting operation again. After the punching is completed, the cylinder drives the two sets of punching dies to move rightward, the right punching die moves to the lower side of the right blanking mechanism 42, and the left punching die moves to the lower side of the main body driving mechanism 31. And the rear blanking mechanism performs blanking operation. After the blanking of the right blanking mechanism 42 is finished, one blanking cycle is finished, including twice blanking and twice blanking, so that two products are obtained. If the production is to be continued, the circulation is continued according to the steps.
In the automatic punching apparatus of this embodiment, when the die transfer device 5 moves up, the two sets of dies continuously and circularly move among the left blanking mechanism 41, the main body driving mechanism 31 and the right blanking mechanism 42, so that the production efficiency is improved.
The automatic punching equipment disclosed by the invention has the advantages that the structural design is reasonable, the punching mode and the waste removal mode after punching are changed, the material of the sticking cloth can be punched, the good effect is achieved, the waste and the blanking are convenient after punching, the small-sized cutter is adopted and is reasonably arranged, the small-hole punching can be carried out on the material stuck with the cloth, the production efficiency is high, and the product quality is good.
