s2: the oil cylinder 9 drives the assembly pressing block 11 to move downwards after being started, and when the assembly pressing block 11 abuts against the upper end of the workpiece 1, the arc-shaped part 2 and the two through holes 3 of the workpiece 1 are machined and formed after the first support plate 13 and the second support plate 20 move downwards continuously;
s3: after the arc-shaped part 2 and the two through holes 3 on the workpiece 1 are machined and formed, the anti-falling mechanism 28 can avoid the material carrying phenomenon, and the material returning mechanism 37 can push the machined workpiece 1 out of the bearing flat plate 6.
The working principle of the device is that an operator firstly places an unprocessed workpiece 1 on a bearing flat plate 6, then an oil cylinder 9 is started to drive an assembly pressing block 11 to move downwards through a pressing plate 8, the assembly pressing block 11 compresses the workpiece 1 after moving downwards, and then the pressing plate 8 continues to move downwards. The pressing plate 8 drives the assembly pressing block 11 to abut against the workpiece 1 through the first spring 10, then when the assembly pressing block 11 continuously moves downwards, the first spring 10 compresses, the second spring 27 compresses, the first support plate 13 and the assembly pressing block 11 slide relatively, the first support plate 13 drives the abutting pressing rod 14 to contact with the sliding pressing rod 15, the abutting pressing rod 14 pushes the sliding pressing rod 15 to displace, the edge of the workpiece 1 can be pushed to bend after the sliding pressing rod 15 moves, and at the moment, the arc through hole 16 of the sliding pressing rod 15 is matched with the arc through hole 12 of the assembly pressing block 11 together so as to limit the bending part of the workpiece 1, and the arc-shaped part 2 of the workpiece 1 is promoted to be generated. At the same time, the downward movement of the second support plate 20 can press-form the two through-holes 3 of the workpiece 1 by means of the two abutment struts 21.
In this process, the second support plate 20 drives the pressing rack 35 to move through the pressing bracket 36, and the pressing rack 35 drives the squeegee 30 to abut against the upper end of the workpiece 1 after moving, so as to prevent the material carrying phenomenon when the two abutting support rods 21 are reset upwards. When the pressing plate 8 moves upwards for resetting, the pressing plate 8 rotates through the switching belt wheel 43 and then drives the material returning support 39 to move through the traction rope 42, the material returning support 39 moves and then drives the material returning insert plate 38 to move through the switching rack 46, and the material returning insert plate 38 can push the workpiece 1 at the upper end of the bearing flat plate 6 to be separated from the bearing flat plate 6 after moving, so that automatic discharging is completed.
