Abstract
A blasting apparatus for blasting a predetermined portion of a work by spraying a powder to the work in a blasting chamber. The blasting apparatus includes a work bed for placing the work thereon, a spray nozzle for spraying the powder onto the work, a first driving section for linearly moving the work bed in a first direction, and a second driving section for linearly moving the spray nozzle in a second direction perpendicular to the first direction. Accordingly, the blasting apparatus can be reduced in size.
Claims39
A blasting apparatus for spraying a powder against a work piece disposed in a blasting chamber, said blasting apparatus comprising:
- a rigid movable workbed on which said work piece is disposable, said workbed comprising a rigid lower plate member which forms an integral part of the workbed, which extends the length of said workbed, which is movable synchronously with said workbed, and which has a funnel-shaped concave configuration adapted to collect powder, said plate member having a first opening formed at its lower apex through which powder can be exhausted;
- a spray nozzle for spraying said powder onto said work piece;
- first means for linearly moving said workbed in a first horizontal direction;
- and
- second means for linearly moving said spray nozzle in a second horizontal direction perpendicular to said first direction;
- particulate matter collection means for collecting spent powder;
- a first hose fluidly interconnecting the first opening formed at the lower apex of said lower plate member with said particulate matter collection means, said first hose being flexible and of sufficient length to allow for workbed movement;
- a stationary funnel-shaped concavely configured panel which is adapted to collect powder and which is disposed below said workbed and formed with a second opening at its lower apex through which powder can be exhausted, said stationary funnel shaped concavely configured panel forming the floor of an enclosure which encloses said workbed and said spray nozzle;
- and
- a second hose fluidly interconnecting the second opening formed at the lower apex of said stationary funnel-shaped panel with said particulate matter collection means.

The blasting apparatus comprising:
- a linearly movable essentially horizontal workbed which is adapted to stationarily support a work piece, said workbed having an integral concave essentially funnel-shaped lower panel member which is rigid with said workbed and which is so shaped and configured as to collect particulate material, said lower panel member extending the length of said workbed;
- first drive means for selectively moving said linearly movable workbed linearly in a first essentially horizontal direction;
- a spray nozzle for spraying a particulate material downward toward said workbed;
- spray nozzle drive means for linearly moving said spray nozzle in a second essentially horizontal direction which is perpendicular to said first direction.
1 more element
A blasting apparatus for fusillading particulate matter against a work piece, comprising:
- an enclosure;
- particulate matter collection means;
- a stationary funnel-shaped floor panel which forms part of said enclosure and in which a first particulate matter exhaust opening is formed, said first opening being fluidly communicated with a particulate matter collection means by way of a first hose;
- a horizontally movable and oriented workbed on which a work piece can be disposed and maintained in a stationary state with respect to said workbed, said workbed being disposed within said enclosure and provided with:
- a lower funnel-shaped panel which forms an integral part of said workbed and which is located below the work piece and arranged to collect particulate matter, and
- a second particulate matter exhaust opening in said lower funnel-shaped panel through which particulate matter can be exhausted to said particulate matter collection means through a second flexible hose;
- a spray nozzle for fusillading particulate matter vertically down onto the work piece which is stationarily supported on said workbed;
- first means for linearly moving said workbed within said enclosure in a first horizontal direction, said first linearly moving means including a wire which is operatively connected with said workbed, which passes a side wall of said enclosure and which is connected with a driven pulley located outside of said enclosure;
- second means for linearly moving said spray nozzle within said enclosure in a second horizontal direction perpendicular to said first direction;
- and
- a cover enclosing said nozzle, said cover being spaced above said workbed so as to be in a contact-free relationship with the work piece on said workbed, said cover having a third port which is fluidly communicated with said particulate matter collection means through a third flexible hose, said port being adapted to suck particulate matter out of a space defined by said cover about said nozzle.
