[0022] Further, as shown in Figures 1-4 , a discharge plate 12 is arranged below the deburring station 3, the discharge plate 12 is fixedly installed on one end of the progressive die 1, when the deburring station 3 completes the processing of the workpiece 10, the workpiece 10 is transferred to the discharge plate 12 by the parallel cylinder 6 pushing the mechanical hand gripper 7, the workpiece 10 is guided to slide along the discharge plate 12 to a designated collection area, so as to facilitate the centralized collection and subsequent arrangement of the processed workpiece 10.
[0023] Further, as shown in Figures 1-4As shown, the lower part of the parallel cylinder 6 is provided with a cylinder fixing seat 13, which is fixedly installed at one end of the progressive die 1.

[0024] As shown in the drawings, Figures 1-4 The principle of the automatic deburring mechanical arm for hardware stamping provided by the embodiment is as follows:
[0025] The raw material is gradually processed on the progressive die 1, and is cut off to form a workpiece 10 according to the specified size when reaching the cutting station 2. Then the parallel cylinder 6 is opened to push the mechanical hand 7. The hand sensor 8 outside the mechanical hand 7 senses the contact state of the mechanical hand 7 and the workpiece 10, so that the grab groove 9 abuts against both ends of the workpiece 10 and grabs the workpiece 10, and moves the workpiece 10 to the deburring station 3. The chamfer block 5 around the stamping groove 4 cooperates with the stamping action of the punch to deburr the periphery of the workpiece 10. At this time, the feed sensor 11 on the progressive die 1 monitors the position of the workpiece 10 in real time. When it is detected that the deburring of the workpiece 10 is completed, a signal is sent to the parallel cylinder 6. The parallel cylinder 6 again pushes the mechanical hand 7 to sense the contact state of the mechanical hand 7 and the workpiece 10 by the hand sensor 8, and then grabs the workpiece 10 and moves it to the discharge plate 12. The discharge plate 12 guides the workpiece 10 to slide along the discharge plate 12 to the designated collection area, so that the workpiece 10 can be deburred all around, and the efficiency and quality of hardware stamping processing can be effectively improved.
