The uniformly arranged telescopic bags 32 are fixedly connected between the core ball 29 and the inner side surface of the cavity; heat conducting grooves 33 which are uniformly distributed are formed in the positions, close to the outer surface of the cooling ball 28, in the flowing holes 31; the interiors of the heat conducting grooves 33 are fixedly connected with air bags 34, and the air bags 34 are communicated with the corresponding telescopic bags 32; the during operation, through setting up gasbag 34 and expansion bag 32, when core ball 29 is in the inside motion of cooling ball 28, the expansion ball that core ball 29 can extrude different positions receives the extrusion, the inside gas of expansion ball can get into gasbag 34, make gasbag 34 expand repeatedly, gasbag 34 and then can promote the inside cooling liquid of heat conduction groove 33 to derive, make new cooling liquid leading-in simultaneously, guarantee to last the cooling effect, the area of contact of cooling liquid with the inside of cooling ball 28 has been increased by a wide margin through heat conduction groove 33 simultaneously, the heat conduction effect is improved.

Referring to fig. 7, a cooling forming process for stainless steel shots, which is suitable for the cooling forming device for stainless steel shots, includes the following steps:

s1: firstly, adding a metal raw material into an induction furnace, then melting the metal raw material into a metal liquid, pouring the metal liquid into an atomizing barrel 4 through a nozzle 2 after the metal liquid is fully melted, and atomizing the metal liquid by high-pressure airflow;

s2: the atomized metal liquid drops are quickly shrunk and formed through the cooling pipe 3 to form fine compact metal particles, meanwhile, the fine compact metal particles are filtered through the filter plate 7 in the cooling pipe 3, the metal particles are screened, and the metal particles which are too fine or too large and special-shaped can be separated out and are re-melted for production;

s3: the filtered qualified metal particles are led into a cooling barrel 20 through a scraper 11 and a connecting pipe 14, cooling gas is led into the cooling barrel 20 through a spray pipe 21 in the cooling barrel 20, the metal particles are further cooled, and the metal particles are fully cooled through the cooling barrel 20 to obtain finished metal particles.

The working principle is that after the metal particles with higher temperature are obtained after being atomized by the atomizing barrel 4, the metal particles can enter the cooling pipe 3 along with the flowing of air flow, and the metal particles can pass through the air jet head 6 in the cooling pipe 3 and simultaneously spray cooling gas to mix the cooling gas into the metal particles, so that the metal particles can be further cooled, and meanwhile, the metal particles after being cooled are filtered by the filter plate 7, so that the larger metal particles and the smaller metal particles are screened out, the qualified metal particles are positioned on the surface of the filter plate 7 in the middle position, and the cooling of the metal particles is accelerated along with the continuous flowing of the cooling gas; by arranging the first motor 8, the first motor 8 can drive the gear 9 to rotate through the rotation of the first motor 8, the gear 9 can drive the corresponding toothed ring 10 to rotate, the toothed ring 10 can drive the filter plate 7 to rotate, so that the filter plate 7 and the corresponding scraper 11 can move relatively, metal particles on the surface of the filter plate 7 can be quickly removed through the scraper 11 and fall into the suction groove 12, and the metal particles are led out through the connecting pipe 14 at the bottom of the suction groove 12, so that the metal particles on the surface of the filter plate 7 are prevented from being adsorbed in a large amount, and the flow resistance is greatly increased; by arranging the fixing ring 15, when metal particles on the surface of the filter plate 7 directly fall off, the metal particles are easy to accumulate at the bottom of the cooling pipe 3, the falling metal particles directly fall on the inner surface of the fixing ring 15 through the fixing ring 15 and are collected by the collecting groove 16 at the bottom position, and when the collecting groove 16 at the bottom rotates to the top position, the metal particles in the collecting groove 16 directly fall into the suction groove 12, so that the metal particles in the cooling pipe 3 are fully led out; by providing the guide plate 17, when the collecting chute 16 is not rotated to the top position, the opening of the collecting chute 16 is already inclined downward at this time, and a part of the metal particles inside the collecting chute 16 easily slip out, for this reason, by providing the guide plate 17 on the side of the scraper 11, when the metal particles in the position of the part fall, the metal particles directly fall into the guide plate 17 and slide into the inside of the suction chute 12 through the guide plate 17; by arranging the vibration membrane 18 in the collecting tank 16 and arranging the vibration ball 19 at the bottom position of the collecting tank 16, when the collecting tank 16 rotates to the top position, the vibration ball 19 at the bottom of the collecting tank 16 can press the vibration membrane 18, so that the vibration membrane 18 swells downwards, and metal particles collected at the bottom of the collecting tank 16 are promoted to be completely led out; by arranging the cooling barrel 20, the problem of insufficient cooling is easily caused because the retention time of metal particles on the surfaces of the cooling pipe 3 and the filter plate 7 is limited, therefore, the metal particles with qualified particle sizes after being filtered inside the cooling pipe 3 can be guided into the cooling barrel 20 through the connecting pipe 14, because the spraying pipe 21 is connected inside the cooling barrel 20, cooling gas can be guided into the cooling cavity through the spraying pipe 21, meanwhile, the rotating shaft 23 can be driven to rotate by the second motor 22, the rotating shaft 23 can drive the rotating disc 24 to rotate, the metal particles inside the cooling barrel 20 can be mixed through the rotating disc 24, and the metal particles can be rapidly and uniformly cooled; by arranging the screen 25, because the metal particles are accumulated at the top of the rotating disc 24, the cooling gas which cannot be fully contacted with the inside of the metal particles is low in cooling efficiency, by arranging the cooling balls 28, the cooling balls 28 and the metal particles are directly mixed, the cooling of the metal particles can be accelerated by the low-temperature cooling balls 28, meanwhile, after the temperature of the cooling balls 28 is increased, the air pressure in the guide grooves is controlled, the guide rods 27 are further controlled to move, when the guide rods 27 move upwards, the guide rods 27 can drive the rotating disc 24 to move upwards, meanwhile, through the relative rotation between the connecting ring 26 and the rotating disc 24, the rotating disc 24 can continuously rotate along with the rotating shaft 23, after the rotating disc 24 moves upwards, the metal particles at the top of the rotating disc 24 can fall through the screen 25, and the cooling balls 28 can move upwards along with the rotating disc 24, and the cooling balls 28 move to the opening position close to the spray pipe 21, the cooling ball 28 can be cooled rapidly, so that the cooling ball 28 can be reused; by arranging the core ball 29 and the liquid bag 30, the cooling liquid is injected into the flow hole 31 of the cooling ball 28, when the cooling ball 28 moves on the top of the rotating disc 24, the core ball 29 in the cooling ball 28 moves, and the core ball 29 repeatedly extrudes the liquid bags 30 at different positions, so that the liquid in the liquid bag 30 and the flow hole 31 flows, and the continuous cooling effect of the cooling ball 28 is further ensured; through setting up gasbag 34 and expansion bag 32, when core ball 29 is in the inside motion of cooling ball 28, the expansion ball that core ball 29 can extrude different positions receives the extrusion, the inside gas of expansion ball can get into the inside of gasbag 34, make gasbag 34 expand repeatedly, gasbag 34 and then can promote the inside coolant liquid of heat conduction groove 33 to derive, make new coolant liquid leading-in simultaneously, guarantee to last the cooling effect, the contact area inside coolant liquid and cooling ball 28 has been increased by a wide margin through heat conduction groove 33 simultaneously, the heat conduction effect is improved.
