Abstract

A cold spray device basically include at least a pedestal, a base plate, a motor, a spray gun, a high-pressure pipe and a rotating joint. The pedestal is configured to support a workpiece in a predetermined orientation. The base plate is disposed in a position away from the workpiece. The motor is arranged to cause the base plate to rotate about a rotational axis. The spray gun is mounted on the base plate so that a spray direction is directed toward the rotational axis. The high-pressure pipe guides a working gas to the spray gun. The rotating joint is provided to a base end of the high-pressure pipe. The high-pressure pipe is arranged along the rotational axis.

First claim

1 . A cold spray device at least comprising:
a pedestal configured to support a workpiece in a predetermined orientation, a base plate disposed in a position away from the workpiece; a motor arranged to cause means that causes the base plate to rotate about a rotational axis; a spray gun mounted on the base plate so that a spray direction is directed toward the rotational axis; a high-pressure pipe connected to the spray gun at a tip end to guide a working gas to the spray gun; and a rotating joint provided to a base end of the high-pressure pipe, the high-pressure pipe being arranged along the rotational axis.

2 . The cold spray device according to claim 1 , further comprising
a first pipe configured to guide a film-forming material to the spray gun; a second pipe configured to guide and circulate cooling water to a nozzle of the spray gun; an electric power supply line configured to supply electric power to a heater that heats the high-pressure pipe; and a signal line for a sensor mounted on the spray gun, the first pipe, the second pipe, the electric power supply line, and the signal line being disposed around the rotational axis.

3 . The cold spray device according to claim 1 , wherein
the base plate includes a first base plate to which the motor is secured, a second base plate on which the spray gun is mounted, and an offset mechanism configured to cause the first base plate and the second base plate to move relative to each other in a first direction orthogonal to the rotational axis.

4 . The cold spray device according to claim 1 , wherein
the rotating joint is disposed on the line of the rotational axis.

5 . The cold spray device according to claim 1 , further comprising
an industrial robot having a hand to which the base plate is mounted, the industrial robot being taught an operation to sequentially move the spray gun to a plurality of film-deposited portions on the workpiece.
