The principle behind Lithium Battery Concrete Nailer commonly used for nail making is that the nail head is formed by pressure between a main disc and a grinding disc. The radius of the main disc is approximately 30-40cm.
A precise step angle of 10° (or several steps to achieve 10°) is required. Because the nail head needs to be compressed, the torque must be as large as possible.
Lithium Battery Concrete Nailer are driven by only a single ordinary three-phase asynchronous motor; the rest are mechanical mechanisms. Given the high speeds of Nail Guns and the positional requirements between components, automatic electrical control is difficult to achieve.
Truly useful Lithium Battery Concrete Nailer for nail head compression use a crankshaft connecting rod mechanism, compressing the nail tip and cutting it off simultaneously.
This also uses a crankshaft connecting rod mechanism; the clamping is a cam + lever mechanism; the feeding mechanism is similar to an overrunning clutch (without a feeding roller).
