In this way, when the push rod of the electric push cylinder 33 is extended, the end of the adjustable conveyor 32 away from the fixed conveyor 34 is tilted upward, and the end of the adjustable conveyor 32 is respectively coordinated with the first placement rack 36 and the second placement rack 37, thereby effectively placing qualified products and unqualified products separately.

[0065] The working principle of the present invention is as follows: when in use, the raw materials to be stamped are placed on the top of multiple through slots opened on the turntable 9 by the mechanical arm, the turntable 9 is driven to rotate by the second driving motor 24 to realize the alternation of the raw materials, and then the screw rod 29 is driven to rotate by the first driving motor, so that the T-shaped frame 28 installed on the screw rod 29 drives the top plate 26 and the fixed rod 27 to move up and down, and the raw materials to be stamped are pushed into the feeding rack 8 by the top plate 26, and then the sliding plate 4 moves up and down, so that the moving rod 7 drives the push block 21 to push the raw materials to the top of the two lower molds 13;

[0066] During loading, when the second driving motor 24 drives the rotating wheel 23 to rotate through the connecting belt 18, the rotating wheel 23 drives the rotating disk 9 to rotate, when the through groove on the rotating disk 9 and the circular groove on the feeding rack 8 and the circular hole on the support seat 10 are on the same axis, the first driving motor 20 drives the screw rod 29 to rotate, and the T-shaped frame 28 mounted on the screw rod 29 moves upward along the two guide pillars 25, so that the fixed rod 27 drives the top plate 26 to push the raw materials on the rotating disk 9 into the feeding rack 8, and the sliding plate 4 moves upward, so that the pushing block 21 inside the feeding rack 8 moves forward along the feeding rack 8 with the cooperation of the connecting rod and the moving rod 7, so that the raw materials are pushed to the top of the two lower molds 13, and the feeding rack 8 is flush with the placement surface of the lower mold 13. In this way, in the process of pushing the raw materials, the retaining edge 30 on the lower mold 13 is used for effective limiting;

[0067] During stamping, the slide plate 4 is driven by the oil cylinder 3 on the top of the support frame 2 to move downward along the slide bar 15. A matching seat 11 is fixedly installed at the bottom of the slide plate 4. Both ends of the matching seat 11 are provided with inclined surfaces. An upper die 12 is also detachably installed in the middle of the matching seat 11. The shape of the upper die 12 is the same as the inner edge shape of the accessory. The downward movement of the raw material is achieved by pressing down the matching seat 11 and the upper die 12 at the same time. At this time, the raw material enters the cavity between the two lower dies 13, and the matching seat 11 is pressed downward. The inclined surfaces at both ends contact with the inclined surfaces on the lower die 13, and through the cooperation between the matching seat 11 and the lower die 13, the two lower dies 13 move inward at the same time, and the two lower dies 13 extrude the raw materials inward, so that the inner wall of the raw materials contacts the edge of the upper die 12, and the semicircular grooves at the bottom of the pressing plate at both ends of the matching seat 11 fit with the transverse slide bar 22. Through the contact between the pressing plate and the lower die 13, the end of the transverse slide bar 22 away from the lower die 13 and the matching seat 16 are squeezed by the spring 14, so that the transverse slide bar 22 moves forward;

[0068] After the stamping is completed, the slide plate 4 drives the matching seat 11 and the upper die 12 to move upward at the same time. At the same time, the two lower dies 13 are moved to both sides under the action of the spring 14 set on the transverse slide bar 22, so that the inner walls of the two lower dies 13 are separated from the stamped exhaust pipe. At the same time, the slide plate 4 drives the movable rotating rod 49 to pull upward, and at the same time pulls the turning table 46 to rotate along the first support rod 43 and the second support rod 44 under the action of the rotating shaft. At this time, the stamped exhaust pipe slides along the guide plate 17, and finally the accessories fall into the adjustable conveyor 32 for the next step of operation;

[0069] When the slide plate 4 moves upward, the slide plate 4 drives the connecting block 6 to realize the moving rod 7 to drive the connecting rod to realize the push block 21 to move forward along the feeding frame 8, so as to push the raw materials pushed by the top plate 26 to the top of the two lower molds 13, so as to realize automatic loading;

[0070] By controlling the push rod of the electric push cylinder 33 to drive the adjustment rod 39 to adjust up and down, the adjustment rod 39 is installed in conjunction with the adjustable conveyor 32, and one end of the adjustable conveyor 32 is movably connected to the fixed conveyor 34. In this way, when the push rod of the electric push cylinder 33 is extended, the end of the adjustable conveyor 32 away from the fixed conveyor 34 is tilted upward, and the end of the adjustable conveyor 32 is respectively coordinated with the first placement rack 36 and the second placement rack 37, so that qualified products and unqualified products can be effectively placed separately.
