Description

Technical Field

[0001] The utility model relates to the technical field of grinding and shot blasting, in particular to a grinding and shot blasting machine for malleable cast iron castings. Background Art

[0002] Malleable cast iron castings are made of white cast iron after high temperature tempering and are often used to make pipeline parts, such as various pipe joints. Malleable cast iron casting pipe fittings are made of malleable cast iron and connected to the pipeline with threads (threads), which can ensure good contact and connection with the pipeline. In the manufacturing process of malleable cast iron castings, in order to remove the oxide scale and sticky sand on the surface, the malleable cast iron castings need to be polished and shot blasted. When the current shot blasting machine is polishing the surface of the malleable cast iron casting, the projectiles will fly out of the seam, which is easy to cause harm to the surrounding staff;

[0003] After searching, the utility model with patent publication number CN219444770U discloses a casting grinding and shot blasting machine. After the casting is poured into the arc-shaped groove of the arc-shaped crawler, the pouring box and the machine door are controlled back to the original position by the third motor, so that the internal environment of the processing body becomes closed again, and then the iron shot that needs to be worked enters the trapezoidal block from the shot inlet pipe, and is accelerated by the acceleration roller to impact the casting on the top of the arc-shaped crawler to grind it. When the grinding is almost done, the discharge door is opened to take out the casting on the top of the arc-shaped crawler. Although it is convenient to reduce the splashing of the projectiles during the grinding process, some of the projectiles will remain on the casting during the grinding process. When the casting after grinding is taken out, the projectiles will be taken out, and the projectiles entrained on the casting need to be manually cleaned and collected, which is easy to reduce the grinding efficiency of the casting.
