Place one end of the unprocessed round tube on the supporting plate (42) after expanding, and make the expanded part cover the two sets of forming parts (310). Then, control the free ends of the two sets of second hydraulic rods (45) to extend to drive the two sets of clamping plates (46) to clamp the round tube, and control the free ends of the third hydraulic rods (48) to extend to drive the two sets of abutting blocks (410) on the rectangular plate (49) to abut the round tube above the round tube to fix the round tube. Then, control the first motor (23) to start. The first motor (23) drives the first bidirectional lead screw (24) to rotate, thereby driving the two groups of T-shaped movable plates (25) to move closer to each other, and driving the two groups of punching dies (26) to move closer to each other until the expanded part of the round tube is punched, and the expanded part of the round tube is punched into a double round tube that is internally connected with the unpunched round tube part to form a spectacle tube together, thereby completing the processing of the spectacle tube.

Then, the two sets of pinch handles (392) are pulled to drive the two sets of positioning rods (391) to separate from the respective positioning grooves. Then, the two sets of clamping blocks (37) can be removed from the respective mounting blocks (34) and replaced with clamping blocks (37) with different sizes of forming parts (310). The second motor (32) is controlled to start, drive the second bidirectional lead screw (33) to rotate, drive the two sets of mounting blocks (34) to move relative to each other and adjust the spacing between the two sets of forming parts (310). When the round tube is placed on the supporting plate (42), the free end of the first hydraulic rod (41) is controlled to move to control the lifting and lowering adjustment position of the round tube, so as to facilitate the adjustment and matching of the processing and stamping position after the size of the round tube changes.
