[0041] More specifically, when the mobile adaptive block 311 is in contact with the extrusion sensor 426 while moving the sliding block 413 upward, the automatic oil injection pump 424 is started to spray oil for a fixed time, when the push block 524 moves upward, the oil in the inside of the oil tank 423 is sucked through the fourth guide hole 527 and the second connecting barrel 528, when the push block 524 moves downward, the spring check valve in the inside of the second connecting barrel 528 is closed so that the oil can only flow out through the oil injection hole 526, when the push block 524 moves upward, the spring check valve flows through the air pressure to suck the oil in the inside of the oil tank 423 into the inside of the connecting barrel 521, and when the push block 524 stops moving, the spring check valve is closed.

[0042] Working principle: In the initial state, the mobile adaptive block 311 is in the upper limit position under the action of the second spring 513, the top of the sliding block 413 protrudes 2-3mm above the surface of the lower die seat 212, and the block 532 in the guide barrel 525 closes the oil injection hole 526 under the action of the third spring 531.

[0044] The stamping forming stage, when the upper module 711 continues to move down, at this time the guide barrel 525 is under the action of the fixed rod 536, the second connecting rod 533 pushes the blocking ring 534 to close the oil injection hole 526, and the oil injection is stopped. The forming cavity of the upper module 711 and the lower die seat 212 jointly complete the stamping forming work of the metal sheet.

[0045] The upper die lifting and ejection stage, the telescopic rod 613 drives the upper module 711 to move up, the second spring 513 pushes the moving adapter block 311 to move up, and then drives the sliding block 413 to move up, so that the top of the sliding block 413 protrudes from the surface of the lower die seat 212, and the formed workpiece is lifted to separate from the die cavity. At the same time, the side surface of the sliding block 413 is in contact with the extrusion sensor 426, triggering the automatic oil injection pump 424 to work, and the lubricating oil is injected into the oil injection hole 414 through the connecting pipe 425 and the guide pipe 421, and is sprayed to the surface of the lower die seat 212 through the oil injection groove 415, preparing for the next stamping.
