[0032] Working principle of the present invention: When in use, the device is connected to electricity and connected to an external PLC control center. The PLC control center cooperates with the control unit 13 to control the opening and closing of the electrical components in the device. The staff places the workpiece 6 to be formed in the support tray 42, and then clamps the workpiece 6 in the support tray 42 separately on the loading assembly 4. The workpiece 6 is limited by multiple groups of clamping seats 45, and multiple groups of workpieces 6 are stacked vertically. Among them, the lowest group of workpieces 6 passes through the through holes on the support seat 44 and enters the push cavity. The loading cylinder 43 is controlled to work and extend, driving the push piece 47 to slide in the push cavity. As the loading cylinder 43 works, the push rod 472 in the push piece 47 and the workpiece 6, at this time, the workpiece 6 is fitted with the arc groove 473, and the feeding cylinder 43 continues to work, pushing the workpiece 6 in the pushing cavity to slide toward the forming component 3 through the pushing member 47. When the workpiece 6 moves to the limiting member 46, the workpiece 6 contacts the hook block 464 in the limiting member 46 and fits with the hook groove 465. The workpiece 6 continues to move under the push of the feeding cylinder 43, thereby driving the hook block 464 to move, so that the inner rod 462 slides in the outer rod 461, and the spring 463 is stretched; When the workpiece 6 moves to the top of the lower die seat 36, the feeding cylinder 43 stops working, controls the forming cylinder 34 to work, moves downward, drives the upper mounting frame 38 and the upper die seat 35 to move downward, and drives the pre-pressing seat 37 to move downward. When the pre-pressing seat 37 moves downward, it first contacts the workpiece 6 and pushes the workpiece 6 downward, so that the workpiece 6 slides out of the hook groove 465 and the arc groove 473 and falls on the lower die seat 36. The hook block 464 and the inner rod 462 are reset under the action of the spring 463, and the feeding cylinder 43 is controlled to retract, driving the pushing piece 47 to reset. At this time, the pre-pressing seat 37 has pre-pressed the workpiece 6 on the lower die seat 36. The forming cylinder 34 continues to move downward, and continues to drive the upper mounting frame 38 and the upper die seat 35 to move downward. The pre-pressing seat 37 slides in the sliding hole of the upper die seat 35 without affecting the upper die seat 35 and the lower die seat 36 to form the workpiece 6. After the workpiece 6 is formed, the forming cylinder 34 stops working. At this time, the workpiece 6 is limited by the upper die seat 35 and the lower die seat 36, and the expanding cylinder 26 in the expanding assembly 2 is controlled to work, driving the mounting seat 24 to move toward the workpiece 6. The mounting seat 24 drives the longitudinal slide 23 to slide on the longitudinal slide rail 22, thereby maintaining the stability of the movement of the mounting seat 24, and controlling the expansion device on the transverse slide 25 to work, and expanding the workpiece 6; After the expansion process is completed, the expansion component 2 and the forming component 3 are controlled to reset, and the ejection cylinder 52 in the unloading component 5 is controlled to work and extend, driving the ejection block 54 to move toward the workpiece 6, and the workpiece 6 is pushed from the lower die base 36 to loosen the workpiece 6 and the lower die base 36. The unloading cylinder 51 is controlled to work and extend, driving the unloading plate 53 to move upward, and the workpiece 6 is ejected from the lower die base 36. Under the action of the inclined surface on the unloading plate 53, the workpiece 6 slides from the lower die base 36 to the receiving plate 12, and under the action of the inclined receiving plate 12, it is discharged from this equipment, completing the automatic forming and expanding process of the workpiece 6.
