[0002] The hardware processing process is to cut the material according to the production needs. After cutting, some small accessories such as small accessories can be sent to the punching machine for processing such as gong cutting, CNC or punching. This is very common in the production of eyeglass accessories and auto parts. When punching, the drill bit punches the cut product through stamping. As the number of punching times increases, the wear of the drill bit also increases. Therefore, it is necessary to detect the diameter of the drill bit to determine the wear and replacement time.

[0003] A punching detection mechanism for hardware processing disclosed in Chinese patent CN212858797U detects the punched hole diameter in real time by setting a detection rod, thereby realizing a comprehensive inspection of punching hardware, providing a popular detection surface, and improving the qualified rate of hardware. However, while solving the problem, the punching detection mechanism for hardware processing has the following defects:

[0004] After the punching is completed in the device, the operating table is adjusted to be placed below the detection rod, and the hydraulic rod is adjusted to drive the wear detection box downward to detect the punching diameter. However, when punching a large number of holes or a single set of hardware is punched at a long distance, the installation frame will occupy a large area, which is not conducive to improving space utilization. Utility Model Content

[0009] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0010] 1. When punching a large number of holes or punching a single set of hardware at a long distance, the device drives the flip frame to flip through the brake motor and then squeezes the self-reset inching switch through the detection rod for detection, so that the detection rod part occupies the high-rise space, thereby reducing the footprint of the punching frame, which is beneficial to improve space utilization.

[0022] The working principle of the utility model is as follows: when in use,

[0023] 1. After the punching is completed in the device, the brake motor 13 is started, and the brake motor 13 drives the flip frame 14 to flip, so that the detection rod 165 is facing downward, and the first hydraulic cylinder 11 is started to move the detection rod 165 downward. If the punching head 151 is worn and the punching diameter is smaller than the diameter of the detection rod 165, the detection rod 165 moves and abuts against the hardware workpiece, so that the detection rod 165 compresses the spring to squeeze the self-reset inching switch 161, thereby energizing the warning light and issuing a replacement prompt.

[0024] 2. When the punching head 151 needs to be replaced, pull the lock head 154, and the lock head 154 pulls the tension spring 153 and the lock pin 155 at the same time, so that the lock pin 155 is separated from the lock pin hole 157, and the restriction on the assembly plate 156 is released.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. After the punching is completed in the device, the brake motor 13 is started, and the brake motor 13 drives the flip frame 14 to flip, so that the detection rod 165 is facing downward, and the first hydraulic cylinder 11 is started to move the detection rod 165 downward. If the punching head 151 is worn and the punching diameter is smaller than the diameter of the detection rod 165, the detection rod 165 will move against the hardware workpiece, so that the detection rod 165 compresses the spring to squeeze the self-reset moment switch 161, and then the warning light is powered on to issue a replacement prompt. When the device is performing multiple punching or a single set of hardware punching distance is far, the brake motor 13 drives the flip frame 14 to flip, and then the detection rod 165 squeezes the self-reset moment switch 161 for detection, so that the detection rod 165 partially occupies the high-rise space, thereby reducing the floor area of ​​the punching frame 10, which is conducive to improving space utilization.

[0027] 2. When the punching head 151 needs to be replaced, pull the lock head 154, and the lock head 154 pulls the tension spring 153 and the lock pin 155 at the same time, so that the lock pin 155 is separated from the lock pin hole 157, and the restriction on the assembly plate 156 is released. Then pull the assembly plate 156, pull the assembly plate 156 out of the assembly frame 152, and replace the punching head 151 on the assembly plate 156. By pulling the lock pin 155 to separate from the lock pin hole 157, the punching head 151 can be quickly replaced, which is more convenient to use.
