After the stamping is completed, the pre-ejection component 8 and the secondary ejection component 9 are respectively driven by the high-pressure gas in the gas storage component 7, and the pre-ejection operation and the secondary ejection operation are performed in turn. This can avoid damage to the lamp housing after the stamping is completed and improve product quality.

After the stamping is completed, the force plate 11 moves upward and resets under the elastic force of the first return spring 14. The mounting tube 10 and the force plate 11 are coaxially arranged. The upper wall of the force plate 11 is fixedly provided with a lower mold 15, and the lower mold 15 is arranged at the center position of the force plate 11. The arrangement of the guide rod 12 and the first return spring 14 can not only play a buffering role in the stamping process, but also make the stamping process more stable and improve the stamping accuracy.

During the stamping operation, when the force-bearing plate 11 is pressed down to the set position, the first electromagnet 19 on the positioning mechanism 17 is in a closed state, and the first positioning rod 20 on the positioning mechanism 17 is buckled to the bottom of the positioning ring 18 under the action of the first locking spring 22, so that after the stamping is completed, the driven stamping mechanism 4 cannot be reset upward, and the driven stamping mechanism 4 is positioned and locked at this time. When the first electromagnet 19 is turned on, the first positioning rod 20 moves in the direction away from the positioning ring 18 under the action of the electromagnetic force, and the unlocking operation can be completed.

When the stamping operation is performed, the extrusion cylinder 23 moves downward following the force plate 11, and the extrusion cylinder 23 drives the closed ring 24 to move downward. Since the closed ring 24 seals the gas cylinder 16, as the extrusion cylinder 23 continues to move downward, the air in the gas cylinder 16 is compressed into high-pressure gas. When the high-pressure gas in the gas cylinder 16 needs to be discharged, the solenoid valve 29 is opened, and the high-pressure gas can be discharged from the multiple groups of ventilation holes 25 through the ventilation pipe 28 and the connecting chamber 27, so that the lamp shell tightly fitted on the lower mold 15 can be impacted and loosened, completing the pre-ejection operation. Since high-pressure gas is used for pre-ejection, the lamp shell will not be damaged during the process, which can effectively improve the product quality.

When ejection operation is required, the second electromagnet 36 is turned on, the second positioning rod 37 moves away from the ejector 30, and the ejector 30 is unlocked, and then the ejector 30 is ejected under the action of the high-pressure gas, completing the secondary ejection operation.

Through the provided position sensor 68, the start and stop positions of the upper mold 42 can be set, thereby controlling the action of the follow-up feeding mechanism 6 that moves synchronously with the upper mold 42, controlling the feeding rhythm and feeding length, and controlling the hydraulic pump 70, the drive motor 56 and various electronic control components through the provided controller 71, so as to realize the automatic control of each step in the stamping process and improve the efficiency of the stamping operation.

[0039] like Figure 1 As shown, the specific working principle is:

[0040] First, place the blank to be stamped on the storage plate 48 so that the blank is close to the limit plate 49, then manually push the blank to the appropriate position above the lower die 15, and set the position of the position sensor 68 according to the blank length required for stamping the lamp shell, that is, set the blank movement length for each automatic feeding, and then turn on the hydraulic pump 70 through the controller 71 to extend the stamping cylinder 40 and drive the upper die 42 to move downward until the upper die 42 fits into the lower die 15 to stamp the blank. During this process, the position sensor 68 detects that the upper die 42 moves downward, and the controller 71 controls the drive motor 56 to start, and controls the moving clamp 57 to move upward through the lifting screw 51, that is, releases the clamping action on the stamping blank, and the transmission device 44 on the follower feeding mechanism 6 is under the power transmission of the push-pull plate 41. The power is transmitted to the clamping moving device 46, driving the first rack 52 to move away from the lower mold 15. At the same time, the power is transmitted to the force plate 11 through the squeezing of the lower mold 15 by the upper mold 42. When the force plate 11 is pressed down to the set position, the first electromagnet 19 on the positioning mechanism 17 is in a closed state. The first positioning rod 20 on the positioning mechanism 17 is snapped to the bottom of the positioning ring 18 under the action of the first locking spring 22, so that after the stamping is completed, the driven stamping mechanism 4 cannot be reset upward. At this time, the driven stamping mechanism 4 is positioned and locked. At the same time, the extrusion cylinder 23 moves downward with the force plate 11, and the extrusion cylinder 23 drives the closed ring 24 to move downward. Since the closed ring 24 seals the air storage cylinder 16, as the extrusion cylinder 23 continues to move downward, the air in the air storage cylinder 16 is compressed into high-pressure gas.

[0041] When the stamping is completed and the stamped lamp housing needs to be taken out, the solenoid valve 29 is opened, and the high-pressure gas can be discharged from the multiple groups of vent holes 25 through the vent pipe 28 and the connecting chamber 27, so that the lamp housing tightly fitted on the lower mold 15 can be loosened under the condition of external pressure difference, completing the pre-ejection operation, the second electromagnet 36 is turned on, the second positioning rod 37 moves away from the ejector rod 30, the ejector rod 30 is unlocked, and then the ejector rod 30 is ejected under the action of the high-pressure gas, completing the secondary ejection operation of the lamp housing. , and then when the first electromagnet 19 is turned on, the first positioning rod 20 moves away from the positioning ring 18 under the action of the electromagnetic force, the driven stamping mechanism 4 resets upward, and the air enters the air storage cylinder 16 from the vent pipe 28, and the push rod 30 retracts under the action of the second reset spring 34. At this time, the second electromagnet 36 on the locking mechanism 31 is closed, and the second positioning rod 37 is extended into the locking groove 35 under the action of the second locking spring 39, thereby locking the position of the push rod 30, and the solenoid valve 29 is closed after the driven stamping mechanism 4 is reset.

[0042] When the stamping is completed and the upper mold 42 moves upward, the position sensor 68 detects the upward movement of the upper mold 42, and the controller 71 controls the drive motor 56 to start, and controls the movable clamp 57 to move downward through the lifting screw 51, that is, clamping the stamping blank, and then under the action of the transmission device 44, drives the first rack 52 to move in the direction close to the lower mold 15, thereby completing automatic feeding.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
