[0002] The screw heading machine is a cold heading equipment with the function of punching one die and two punches. It is mainly used for forming the head of screw products. It can produce common products such as ordinary self-tapping screws, electrical screws, miniature screws, internal and external hexagonal bolts, self-drilling screws, fiberboard screws, etc.

[0003] Since the die of the screw heading machine is prone to deviation and displacement after working for a long time, some defective products will appear during screw processing. In order to improve the discharge quality of the screws, a detection head is usually installed at the discharge end of the screw heading machine. When unqualified screws are detected, the machine stops operating. After that, the operator needs to take out the unqualified products on the conveying device one by one. Not only is the sorting speed slow, but the downtime will also affect the production efficiency of the screws. Utility Model Content
