Abstract
The application relates to the technical field of pneumatic rivet tools, and discloses a pneumatic core-pulling rivet tool which comprises a rear shell, one end of the rear shell is provided with a front shell, the rear shell and the front shell are made of high-strength aluminum alloy, a gas cylinder is arranged in the rear shell, a piston rod is inserted into an inner wall of one end of the gas cylinder, a rivet head is arranged at one end of the piston rod, a protective head is arranged at one end of the rivet head, the protective head is in a conical boss shape, and the rivet head and the protective head are made of high-hardness alloy steel. The pneumatic core-pulling rivet tool can adjust the gas pressure entering the gas cylinder through an adjusting valve, thereby controlling the pushing force of the rivet head and the protective head, and the first spring and the shock-absorbing pad can absorb the excess impact energy, so that the stable riveting force can be provided, the damage to the workpiece surface is reduced, the excess impact energy is effectively absorbed, the workpiece is protected from additional damage, the service life of the tool is prolonged, and the maintenance cost is reduced.
