Numerical control machining device for key bit tooth punching

[0002] As locks are more and more widely used in people's lives, and the lock industry is becoming more and more developed, the anti-theft performance of locks is the main criterion for consumers to choose locks, that is to say, the anti-theft performance of a lock determines that it will It will not be accepted and liked by consumers, and the anti-theft performance of the lock is mainly reflected in the production of key cutouts. There are two types of cutouts for arc-shaped keys in the prior art: the first is punching, which is divided into two types: For manual punching and CNC punching, manual punching is to make a corresponding number of molds according to the code of the tooth pattern for production. This method has high efficiency, but the cost of mold manufacturing is limited, and only limited molds can be used in actual production. , can not meet the diversity of key teeth, and it is easy to have repeated teeth, which increases the possibility of mutual opening of the produced locks and reduces the safety of the locks; CNC punching is to use the CNC system to control the cross carriage To carry out punching of key cutouts, the CNC center can automatically update the cutout codes, control the movement of the cross slide, make the cutout codes in key production more comprehensive, reduce the mutual opening rate of keys, and increase production efficiency

Another way is to mill the teeth. In order to improve the life of the key and reduce the cost, most manufacturers use iron, which is harder than copper and aluminum, as the material of the key. Barbs are generated, therefore, after the key is processed, the staff need to polish the periphery of the key to remove the barbs, which not only increases the workload of the staff, but also affects the accuracy of the key
