Provided is a shot peening device with which recovered projection material and foreign bodies can be more precisely separated while inhibiting an increase in the size of the device. The shot peening device is provided with: a projector which projects projection material onto a workpiece (W); recovery mechanisms which recover the projection material projected by the projector; and a wind power sorting mechanism in which recovered projection material is allowed to fall freely while an upward air current is applied to the recovered projection material, and foreign bodies included in the recovered projection material are separated from the recovered projection material.

Shot processing machine

The present invention provides a drum for a shot blasting apparatus that uniformly treats the works to be treated by increasing the level of agitation of the works that are buried at the bottom of the drum, and, further, suppressing the traces of collisions on the works, which traces are caused by the works colliding with each other. The drum comprises a hollow middle part, a lower-half part having the shape of a truncated cone, having a closed bottom, and having a projecting part for agitating that is connected to both the lower-half part and the middle part, and that agitates the works, wherein the projecting part for agitating has at least two surfaces, one being the surface for picking-up the works and the other being the surface for having the works slide down. The present invention also provides the shot blasting apparatus using the drum.

Drum for a shot blasting apparatus and shot blasting apparatus

To provide a novel shot-blasting machine to eliminate a dead space for a cover that shuts an opening for feeding and taking out works and to open and close the cover by moving a rotary drum around an axis. The machine has a cabinet, a rotary drumhaving holes, and a centrifugal shooting machine. The rotary drummoves, within the cabinet, around an axis through the positions for feeding, processing, and taking out the works. The cabinetcomprises a coverfor shutting an openingfor feeding and taking out the works. It has a wallfor sealing the side of the opening. The coveris integrated with the rotary drumto move around the axis. It has wallsthat fit the wallfor sealing. Lip sealsseal the gap between the wallsof the coverand the wallfor sealing.

Shot-blasting machine

A shot-peening device(s) is installed on a side of a cabinet defining an ejection chamber in the cabinet. Shots ejected from the device to a workpiece fall and are conveyed in a horizontal direction by a horizontal screw conveyor positioned above a lower end of the cabinet and then conveyed upward by a vertical screw conveyor whose base end is above the lower end of the cabinet. The shots pass from an upper section of the vertical screw conveyor through a chute to reach an opening/closing gate. When the gate is opened and the shots are supplied to the device(s) for re-ejeciton, a portion of the shots is cause to overflow from the gate. The overflowed shots are caused to pass through a separator to remove impurities and then returned to the horizontal screw conveyor.
