[0002] Aviation steel shot is a kind of metal shot used for shot peening, usually made of high-strength steel. They are widely used in aerospace, automobile, machinery and other fields for surface treatment and enhancing the fatigue strength of materials.

[0003] The production of aviation steel shot is a complex and delicate process that requires strict control of each link to ensure the quality and performance of the final product. The following are the main steps and process flow of aviation steel shot production: 1. Raw material selection: High carbon steel or alloy steel is usually used. These materials have high hardness and wear resistance and are suitable for the production of aviation steel shot; 2. Steel smelting: Use electric furnace or converter to smelt steel to ensure the purity of molten steel, remove impurities and gases, and adjust the chemical composition of molten steel as needed, and add necessary alloy elements; 3. Steel shot molding: Pour the molten steel into a high-speed rotating mold and use centrifugal force to make it The molten steel is evenly distributed and quickly cooled to form, or the molten steel is sprayed at high pressure to make it quickly cool and solidify in the air to form steel shots; 4. Heat treatment: The formed steel shots are heated to an appropriate temperature, then quickly cooled and quenched to improve their hardness and strength. After quenching, they are tempered to eliminate internal stress and improve the toughness and fatigue resistance of the steel shots; 5. Surface treatment: Polishing to make the surface smooth, coating with anti-rust oil or phosphating to prevent rust, etc.; Finally, the surface-treated aviation steel shots are discharged through the discharge port of the polishing machine and bagged.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1: This embodiment is intended to solve the problem that aviation steel shot needs to be bagged after production and polishing. The prior art usually requires manual support of the bag mouth at the discharge port of the polishing machine so that the aviation steel shot falls into the bag through the discharge port, and then the full bag is removed. However, this process requires a lot of manpower, time and effort, and is likely to affect production efficiency. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10A kind of aviation steel shot production equipment includes a packing bag 10 and a polishing machine 100. A discharge hopper 110 is arranged on the side of the polishing machine 100. A base 120 is connected to the side of the polishing machine 100. A turntable 130 is rotatably arranged on the upper side of the base 120. The turntable 130 is used to place the packing bag 10.

When the sliding rod 150 is located in the deep groove 173, the pressure plate 160 is in contact with the upper side of the support ring 140.

[0045] An opening and closing mechanism 180 for controlling opening and closing is provided on the inner side of the discharge hopper 110. The opening and closing mechanism 180 includes a gear ring 181 rotatably provided on the inner side of the discharge hopper 110, a baffle 182 rotatably provided on the inner side of the discharge hopper 110, a first rack 183 installed on the outer side of the baffle 182 and meshing with the inner ring of the gear ring 181, and a first gear 184 rotatably provided on the inner side of the discharge hopper 110. The first gear 184 meshes with the outer ring of the gear ring 181. The number of baffles 182 is set to be several. When several baffles 182 contact each other, the baffle 182 blocks and closes the outlet of the discharge hopper 110. When several baffles 182 move away from each other, the baffle 182 releases the blocking of the outlet of the discharge hopper 110, so that the discharge hopper 110 is opened.

[0046] A shaft 190 is inserted into the middle of the first gear 184, and a torsion spring 191 is installed on the upper side of the first gear 184. The torsion spring 191 is sleeved on the outside of the shaft 190, and the two ends of the torsion spring 191 are respectively connected to the first gear 184 and the inner wall of the discharge hopper 110, and the lower end of the shaft 190 passes through the bottom side of the discharge hopper 110, and a second gear 192 is installed at the bottom of the shaft 190. The second gear 192 is located outside the discharge hopper 110, and second racks 193 are installed on the outside of the support ring 140. The second racks 193 are intermittently meshed with the second gears 192 respectively. A conveyor belt 200 is arranged on the side of the turntable 130, and a connecting platform 210 for transferring the packaging bag 10 is arranged between the turntable 130 and the conveyor belt 200. A push plate 220 is movably arranged on the upper side of the turntable 130, and the push plate 220 is used to push the packaging bag 10 onto the conveyor belt 200.

[0047] This embodiment also includes a production process for aviation steel shot, including the following specific steps:

[0048] S1. Fixing of the packing bag 10: The packing bag 10 is placed on the turntable 130, and the bag opening of the packing bag 10 is rolled outward and sleeved on the support ring 140. When the turntable 130 drives the packing bag 10 to move below the discharge hopper 110, the pressing plate 160 presses down on the bag opening of the packing bag 10;

[0049] S2. Bagging of aviation steel shot: The closed discharge hopper 110 is opened by setting the opening and closing mechanism 180, so that the aviation steel shot polished in the polishing machine 100 falls into the packing bag 10 through the discharge hopper 110, and then the packing bag 10 moves away from the discharge hopper 110, and the discharge hopper 110 is closed again by the opening and closing mechanism 180;

[0050] S3. Transportation of aviation steel shots: The packaging bag 10 containing aviation steel shots is moved to the end of the conveyor belt 200 and is pushed onto the conveyor belt 200 for transportation by the push plate 220 .

[0051] In this embodiment: the packing bag 10 is placed on the turntable 130, and the bag mouth of the packing bag 10 is rolled outward and sleeved on the support ring 140. When the turntable 130 drives the packing bag 10 to move below the discharge hopper 110, the slide bar 150 passes through the connecting groove 172 and slides from the shallow groove 171 into the deep groove 173, so that the pressing plate 160 presses down on the bag mouth of the packing bag 10, thereby fixing the packing bag 10 on the support ring 140;

[0052] Moreover, in this process, the second gear 192 drives the first gear 184 to rotate through the meshing of the second rack 193 and the second gear 192, and the meshing of the first gear 184 and the gear ring 181 drives the gear ring 181 to rotate, and then the meshing of the gear ring 181 and the first rack 183 drives the baffle 182 to rotate, so that the torsion spring 191 is compressed, and the baffles 182 move away from each other, thereby opening the closed discharge hopper 110, so that the polished aviation steel shot in the polishing machine 100 falls into the packing bag 10 through the discharge hopper 110, and then the packing bag 10 moves away from the discharge hopper 110, and under the action of the rebound force of the torsion spring 191, the discharge hopper 110 is closed again through the opening and closing mechanism 180;

[0053] Finally, the packing bag 10 containing aviation steel shots is moved to the end of the conveyor belt 200 and is pushed onto the conveyor belt 200 for transportation by the push plate 220, thereby improving production efficiency and solving the problem of bagging the aviation steel shots after production and polishing as much as possible. The prior art usually requires manual support of the bag mouth of the packing bag at the discharge port of the polishing machine so that the aviation steel shots fall into the packing bag through the discharge port, and then the filled packing bag is removed. However, this process requires a lot of manpower, is time-consuming and labor-intensive, and can easily affect the problem of production efficiency.

[0054] It should be noted that the inner diameter of the support ring 140 is larger than the outlet diameter of the discharge hopper 110 to prevent the aviation steel shots from spilling outside the packing bag 10, and when the packing bag 10 moves to just below the discharge hopper 110, the turntable 130 and the packing bag 10 pause for an appropriate period of time to allow the aviation steel shots in the discharge hopper 110 to be filled into the packing bag 10. At the same time, during the pause of the turntable 130, the push plate 220 pushes the packing bag 10 more smoothly to the conveyor belt 200 through the connecting platform 210, so that loading and transportation can be carried out simultaneously, further improving the production efficiency.

[0055] Embodiment 2: This embodiment is intended to promote the solution of the problem that it is inconvenient to control the push plate 220 to push the packing bag 10, which easily affects the production and transportation efficiency. This embodiment is an improvement made on the basis of embodiment 1.

A telescopic member 231 is installed on the top of the column 230, and the telescopic member 231 is set as an electric telescopic rod, and the push plate 220 is fixedly connected to the telescopic end of the telescopic member 231.

[0056] A first cable 232 is provided on the inner side of the column 230, and a first electric contact pin 233 is installed on the outer side of the column 230. The two ends of the first cable 232 are electrically connected to the telescopic member 231 and the first electric contact pin 233 respectively. A second electric contact pin 234 is slidably inserted on the inner side of the turntable 130. The number of the second electric contact pins 234 is the same as the number of the support ring 140. A second cable 235 is also provided on the inner side of the turntable 130. The number of the second cables 235 is the same as the number of the second electric contact pins 234. One end of each second cable 235 is electrically connected to the corresponding second electric contact pin 234. The other end of the second cable 235 constitutes a parallel circuit, and the parallel circuit is provided with electric energy through an external power supply. Several second electric contact pins 234 are intermittently in contact with the first electric contact pin 233 respectively. Springs 236 are installed on the ends of the second electric contact pins 234, and the ends of the springs 236 are connected to the inner wall of the turntable 130.

[0057] In this embodiment: when the packing bag 10 filled with aviation steel shot stays at the end of the conveyor belt 200, the second electric contact pin 234 is squeezed and contacted with the first electric contact pin 233 as the turntable 130 rotates, so that the second electric contact pin 234 retracts into the turntable 130, and at the same time the spring 236 is compressed, so that the second electric contact pin 234 contacts the first electric contact pin 233, so that they maintain good electrical contact, and then through the first cable 232 and the second cable 235, the telescopic member 231 and the external power supply form a complete circuit loop, so that the telescopic member 231 drives the push plate 220 to push the packing bag 10 onto the conveyor belt 200 and then retracts and resets, thereby improving production and transportation efficiency.

[0058] Embodiment 3: This embodiment is intended to solve the problem that it is inconvenient to control the rotation of the turntable 130 and the conveyor belt 200, thereby making it inconvenient to move the packaging bag 10.
