Shot blasting machine for producing relay valve cover

Abstract

The invention relates to a shot blasting machine for producing a relay valve cover, which comprises a rack and a plurality of stop levers which are horizontally arranged, the stop levers are connected to the rack, the plurality of stop levers are arranged side by side, a distance exists between adjacent stop levers, the distance is smaller than the diameters of shots, and the distance is used for enabling sundries to pass through. The shots and the sundries fall together, the shots fall onto the stop levers and roll to the positions between the adjacent stop levers to be blocked, at the moment, the peripheral spherical surfaces of the shots abut against the peripheries of the two stop levers, the two abutting positions are in point contact, and therefore the shots are prevented from blocking gaps between the adjacent stop levers; and the sundries fall onto the stop levers and can slide down from the space between the adjacent stop levers or the space between the peripheries of the shots and the peripheries of the stop levers, so that the separation of the shots and the sundries is realized.

Description

technical field [0001] The present application relates to the field of casting equipment, in particular to a shot blasting machine for producing relay valve covers. Background technique [0002] The shot blasting machine (shot blasting machine) used to produce relay valve covers refers to casting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine used for the production of the relay valve cover can shake out sand, remove core and clean the casting at the same time. [0003] When working, the shot blaster uses the high-speed rotating impeller to project the projectile in a certain direction under the action of high centrifugal force, and then project a high-speed and dense projectile beam. The projectile hits the casting, so that the oxide skin and sand on the surface of the casting are quickly Come off and get a smooth surface with a certain roughness. [0004] When working, the proj...

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that when the projectile falls on the filter, the projectile is easy to roll on the filter and roll into the mesh. At this time, the projectile If the mesh is blocked, the debris cannot pass through the mesh and stay on the filter, resulting in the inability to complete the separation of projectiles and debris
