Technical Field

[0001] This invention relates to the field of steel shot production technology, and in particular to a steel shot processing and preparation system. Background Technology

[0002] Shot blasting is a mechanical surface treatment process, similar to sandblasting and shot peening. Its principle involves using a motor to drive an impeller to rotate, and through centrifugal force, projectiles onto the surface of the workpiece, achieving a certain surface roughness to improve its appearance. Alternatively, it can change the tensile stress during welding to compressive stress, thereby extending the workpiece's lifespan. It is used in almost all mechanical fields, such as shipbuilding and repair, automotive parts, aircraft components, gun and tank surfaces, bridges, steel structures, glass, and steel pipes.

Multiple diversion paths 455 are evenly distributed on the diversion cone surface 454. The inner end of the diversion path 455 is open.

[0098] The lower plate 453 has a plurality of forming holes 456 around its perimeter, and the position and number of the forming holes 456 correspond one-to-one with the flow divider 455.

[0099] The working principle and beneficial effects of the above technical solution:

[0100] This invention provides a steel shot processing and preparation system. Before preparing steel shot, impurities on the surface of the raw material need to be removed. A shot peening machine can be used to treat the surface impurities. After treatment, the raw material is conveyed into a melting furnace. The heating function of the melting furnace is started to melt the raw material. During the melting process, a negative pressure dust collector must be continuously operated to treat the dust and gas impurities generated during melting. After melting, the molten liquid is put into a shot making machine 22 and falls into a steel shot forming plate 45. The molten liquid is divided by a diversion cone 454 and formed into steel droplets through forming holes 456. Then, it falls into a receiving liquid 42 to cool and solidify. Finally, it is normalized, quenched, and tempered in a heat treatment furnace 23. In the molten state, after the steel is fed into the shot making machine 22, the steel shot forming plate 45 needs to be in a rotating state. Relying on centrifugal force, steel shots of various shapes are thrown out. The steel shots finally fall into the receiving liquid 42 to cool and solidify. Because the steel shot forming disc 45 is constantly exposed to molten steel at high temperatures, it is easily damaged and therefore needs to be replaced frequently. However, the temperature of the molten steel shot receiving liquid 42 is high, making it difficult and dangerous to replace the steel shot forming disc 45 inside the shot maker 22. Therefore, the shot maker 22 needs to be able to drive the steel shot forming disc 45 to rotate during shot making and also needs to be able to eject the damaged steel shot forming disc 45 for replacement when it needs to be replaced. To this end, the shot maker 22 of this invention is equipped with an action table 44, which rotates forward to drive the steel shot forming disc 45 to rotate around its own central axis to make shot, and rotates in reverse to eject the steel shot forming disc 45 from the protective housing 41 for replacement. The power source is a motor 4410 located inside the protective housing 41, which drives the second drive gear 448 to rotate via a pulley 449. In the first operating state, the second brake disc 4415 is disabled and can rotate, while the first brake disc 4414 is locked. At this time, the second drive gear 448 drives the first bevel gear 4411 to rotate coaxially, and the intermediate bevel gear 4413 also rotates. The meshing of the intermediate bevel gear 4413 also drives the second bevel gear 4412 to rotate. Since the second bevel gear 4412 is coaxially arranged with the first drive gear 447, the first drive gear 447 also rotates accordingly. In the first operating state, the second drive gear 448 rotates clockwise, and the first drive gear 447 rotates counterclockwise. In the second operating state, the second brake disc 4415 is locked, and the first brake disc 4414 is unable to rotate. At this time, the second drive gear 448 drives the first bevel gear 4411 to rotate coaxially. Since the intermediate bevel gear 4413 is fixed to the first brake disc 4414, it forms a planetary gear transmission. During the planetary process, it drives the second bevel gear 4412 to rotate, and the first drive gear 447 also rotates accordingly. In the second operating state, the second drive gear 448 rotates clockwise, and the first drive gear 447 also rotates clockwise.Since the first driving gear 447 meshes with the first driven gear 445, and the second driving gear 448 meshes with the second driven gear 446, in the first working state, the first driven gear 445 and the second driven gear 446 rotate in opposite directions. Therefore, the outer cylinder 441 and the inner cylinder 442 rotate in opposite directions. During their opposite rotation, the limiting post 443-1 moves vertically upward under the limiting action of the first spiral groove 441-1 and the second spiral groove 442-1. The limiting post 443-1 also moves vertically upward with the rotating lifting cylinder 443, thereby pushing the steel shot forming disc 45 out of the protective box 41 for replacement. In the second working state, the first driven gear 445 and the second driven gear 446 rotate in the same direction. Therefore, the outer cylinder 441 and the inner cylinder 442 rotate in the same direction. During their rotation, the limiting post 443-1 will rotate in the same direction under the limiting action of the first spiral groove 441-1 and the second spiral groove 442-1. The limiting post 443-1 will also rotate in the same direction with the rotating lifting cylinder 443, thereby causing the steel shot forming disc 45 to rotate around its own central axis to generate centrifugal force and thus form shot.

[0101] The present invention provides a steel shot processing and preparation system that can produce steel shot for shot peening in a more efficient and standardized manner.

[0102] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
