[0068] Furthermore, the alarm component 32 here can be a light alarm, a sound alarm, or an integrated light and sound alarm. The alarm component 32 here is a common and easy-to-purchase device on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0069] The specific working process of the utility model is that the lower mold body 1 is used to connect the workpiece to be processed, the upper mold body 2 can slide close to or away from the lower mold body 1 to complete the stamping process, the power supply 31 is connected to the upper mold body 2, the alarm component 32 is connected to the upper mold body 2, and is electrically connected to the positive or negative pole of the power supply component 31, the electric contact 33 is connected to the lower mold body 1, the power supply component 31 can slide close to the lower mold body 1 with the upper mold body 2, and abut against the electric contact 33, so that the power supply component 31 and the alarm component 32 are electrically connected to trigger the alarm component 32 to alarm. Compared with the prior art, by placing an alarm component 32 on the mold, wherein the alarm component 32 is triggered by the power supply component 31 sliding close to the lower mold body 1 with the upper mold body 2, and abutting against the electric contact 33, so that the power supply component 31 and the alarm component 32 are electrically connected to trigger the alarm component 32 to alarm, it can assist workers in judging whether the stamping or hole turning process of the workpiece is qualified, and avoid taking the workpiece off for measurement or observation.

[0070] When in use, first install the connecting body 311 and the connecting seat 331 on the upper mold body 2 and the lower mold body 1 respectively, then drive the upper mold body 2 to slide close to the lower mold body 1, and then the two first electric contacts 313 are abutted against the second electric contact block 332. At this time, electrical conduction is formed between the power supply 312, the two first electric contacts 313, the second electric contact block 332 and the alarm component 32, and finally the alarm component 32 alarms, indicating that the stamping is qualified.

[0071] Furthermore, when in use, either or both of the two first electrical contacts 313 are not in contact with the second electrical contact 332. At this time, no electrical conduction is formed between the power supply 312, the two first electrical contacts 313, the second electrical contact 332 and the alarm component 32, and the alarm component 32 cannot sound an alarm, and the stamping is unqualified.

[0072] The device, through the above structure, can solve the technical problem in the prior art that the workpiece needs to be removed after processing to determine whether the stamping or hole punching processing of the workpiece is qualified through measurement or observation, which leads to complicated operation and easily causes deviation in secondary processing.
