Mortise lock case riveting machines insert required components into the stamped case. The various components are riveted to the case. The large mortise cylinder hole is tapped. An operator manually loads the case. Vibratory feeder bowls then automatically feed all smaller components. After assembly is complete, the lock case is automatically unloaded to a chute. Pins can be loaded by the bowl feeder. Lock cases can be loaded by grid conveyor. Pins and the case are put on the fixture, and then the riveting head will rivet them together. If you need the tapping function for the big hole of the lock case, the tapping station can be added into this machine. We can also add one station for manual loading the pins or other parts which are seldom used.
