A powder supply device includes a hopper accommodating powder, a cylindrical roller provided below the hopper and rotatable around a rotational axis, and a wall surface storing the powder in a space between the roller and the wall surface. The powder supply device moves the powder stored between the roller and the wall surface in a rotation direction of the roller and drops the powder by the roller rotating. A plurality of groove portions extending in an axial direction are formed in a peripheral surface of the roller. At least one of the groove portions is formed such that a capacity allowing the powder to be accommodated changes in the axial direction.

Powder supply device and additive manufacturing device

A device for coating a cylinder includes a coating head capable of being inserted into the cylinder, a plurality of coating guns which are provided on the coating head and are configured to discharge a coating material in a direction intersecting a longitudinal direction of the coating head, and a rotating cover which, when the coating material is discharged from one of a first coating gun and a second coating gun among the plurality of coating guns, is configured to cover the other of the first coating gun and the second coating gun, in which the plurality of coating guns are connected to coating material supply devices of different systems, respectively.

A three-dimensional modeling device includes a table supporting a powder material and a model created from the powder material, a processing section disposed so as to face the table and obtaining the model by processing the powder material, and a rotation unit causing the table to rotate relative to the processing section around a rotary axis. The processing section has a plurality of processing units disposed around the rotary axis. The processing units supply the powder material to the table, preheat the supplied powder material, and emit an energy beam to the preheated powder material.

Three-dimensional modeling device

An oscillation jig includes: an oscillation jig base connected to an oscillation table; a first clamp member provided in the oscillation jig base; a second clamp member located at a position opposed to the first clamp member in an oscillation direction and configured to hold a first metal component together with the first clamp member; a link mechanism provided in the oscillation jig base, composed of a plurality of links connected together, connected to the second clamp member, and caused to extend and contract in the oscillation direction; and a clamp actuator configured to cause the link mechanism to extend and contract in the oscillation direction. When the first clamp member and the second clamp member hold the first metal component, a connection center line connecting connection centers of the respective links is made straight in the oscillation direction.

Linear friction welding apparatus

A long shaft inner surface machining apparatus of the present invention includes: a long shaft support devicethat fixes a long shaftso as not to bend; a machining headcapable of being inserted into the prepared holeof the long shaftin the axial direction; a head support devicethat is coupled with the machining headfrom one end of the long shaftthrough the prepared holeand moves the machining headin the axial direction; and a blade drive devicethat is coupled with the machining head from the other end of the long shaftthrough the prepared holeand rotary-drives the bladearound a shaft axis.
