Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, and specifically relates to a shot blasting machine without dead angles for processing castings. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core and clean castings. In some areas, it is also called sandblasting machine or sandblasting machine.

[0003] According to the search, Chinese patent literature, announcement number: CN209698831U, discloses a hook-type shot blasting machine for casting processing, in which steel balls enter the output end of the driving motor through the steel ball inlet, and are then sprayed onto the surface of the casting inside the rust removal bin by the driving motor. The steel balls collide and rub against the casting and eventually fall onto the top surface of the partition, and fall into the collection bin through the leakage holes opened on the surface of the partition for collection. At this time, the transmission motor is driven to run, and the transmission motor drives the conveying rod to rotate, and the steel balls inside the collection bin are conveyed to the discharge port through the conduit, and discharged from the rust removal bin from the discharge port, so as to facilitate the timely removal of the steel balls inside the rust removal bin, so that the steel balls can be recycled in time, thereby improving the continuous working ability of the equipment, reducing the production cost, and improving the work efficiency.

[0004] However, in the actual operation process, after the steel balls remove the oxide layer, rust spots, etc. on the surface of the casting, the volume of the rust dust is smaller than that of the steel balls, so the rust dust will fall into the collection bin from the leak holes of the partition together with the steel balls. In this way, the recovered steel balls are mixed with a lot of rust dust, which requires cleaning before the recovered steel balls can be used. The recovered steel balls cannot be used directly.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content
