The protruding height of the limit nail 529 is adjustable, so that the pressing depth of the nose bridge male die 515 is adjusted, and the requirements of various curved surfaces with different depths are met.

Each nose bridge 514 is pivotally connected to a corresponding side of the bottom of the slide block 512 by a pivot 530 and pivotally connected to the bottom end of the first slide 521 by a pivot 531.

The nose bridge 514 includes a connecting rod 532, a plate 533 rotatably connected to the connecting rod 532, and a silicone mold 534 fixedly connected to a lower portion of the plate 533.

Then, the nose bridge pressing cylinder 517 extends out to drive the nose bridge male die 515 to press downwards and keep for a certain time, so as to form a required curved surface at the nose bridge of the spectacle frame. Finally, the nose bridge pressing cylinder 517 retracts, and the nose bridge male die 515 moves upwards; the facing cylinder 511 retracts, and the upper die 510 opens and resets to complete a facing operation.

Initially, the waste bin 620 is positioned on the front side of the frame 610 and the outlet bin 640 is positioned in the center of the frame 610 and opposite to the window 112 of the support plate 110. When the temperature of the lens frame output by the heating device 300 does not meet the temperature requirement of the forming curved surface, the separating cylinder 630 pushes the waste material box 620 to slide to the center of the frame body 610, so that the lens frame falls into the waste material box 620. On the contrary, when the temperature of the mirror frame output by the heating device 300 meets the temperature requirement of the forming curved surface, the separating cylinder 630 retracts to drive the waste material box 620 to reset, so that the material outlet box 640 is opposite to the window 112, and the mirror frame drops out of the material outlet box 640 after being processed by the curved surface device 500.

A torsion spring 553 is disposed on the rotation path of the locking buckle 550, one end of the torsion spring 553 abuts against the bearing seat 5422, and the other end abuts against the locking buckle 550. Initially, the lock cylinder 551 is retracted, the torsion spring 553 is in a natural position, the lock button 550 is locked in the lock block 5432, the lower base 543 is restrained from rotation, and its die face 5437 is upward for receiving the heated frame. When the lock cylinder 551 extends, the lock catch 550 is pushed away from the lock block 5432, causing the torsion spring 553 to deform. At this time, the rotary cylinder 542 can drive the lower mold base 543 to rotate. When the locking cylinder 551 retracts, the deformed torsion spring 553 generates elastic force to drive the locking buckle 550 to reset and is buckled with the locking block 5432.

A lower die cylinder 5433 is arranged in the lower die seat 543 and used for locking the mirror frame on the lower die 540. In this embodiment, an elastic member 5434, such as a spring, is connected between the lower mold cylinder 5433 and the nose bridge die 545.

When the spectacle frame slides down, the spectacle frame leans against the material pushing net 5652, and the nose bridge part of the spectacle frame is embedded with the top block 5653. The pushing support 5651 is fixedly connected to a pushing block 562 through a first sliding plate 566. The pushing cylinder 561 extends out to push the pushing slider 562 and drive the first sliding plate 566 and the pushing element 565 to move forward toward the lower die base 543; otherwise, a pushing cylinder 561 retracts to drive the pushing component 565 to reset.

The two pushing cylinders 563 extend out to push the two pushing sliders 564 to move toward the lower seat 543, and the pushing rods 568 of the second sliding plates 567 push the material members 565 to move synchronously therewith. Preferably, an elastic member 569 is disposed between the pushing support 5651 of the pushing member 565 and the second sliding plate 567, and when the two pushing cylinders 563 retract, the elastic member drives the pushing member 565 to return.

When the piston rod of the material returning cylinder 5471 extends out, the material returning cylinder 5471 and the material returning slide block 5472 are driven to slide relative to the second slide plate 567, so as to drive the material stopping piece 5473 to move backwards and be far away from the lower die holder 543. Preferably, an elastic member 5475 is disposed between the material returning cylinder 5471 and the material pushing bracket 5651 of the material pushing member 565, and when the material returning cylinder 5471 retracts, the elastic member 5475 drives the material returning mechanism 547 to reset.

Preferably, as shown in fig. 10 and 16, the lower mold 540 further includes a centering mechanism 549 for finely adjusting the position of the dropped frame so as to align with the lower mold seat 543. The centering mechanism 549 comprises a centering electric shaft 5491, a left slider 5493 and a right slider 5493 driven by the centering electric shaft 5491, and a left spring plate 5495 and a right spring plate 5495 respectively connected to the left slider 5493 and the right slider 5493.
