Description

Technical Field

[0001] The invention relates to the technical field of metal powder granulation, in particular to a magnesium alloy spherical particle forming device and a forming process thereof. Background Art

[0002] Magnesium alloys are widely used in many fields such as automobiles, aerospace, electronic equipment and daily necessities due to their light weight, high strength and good mechanical properties. Magnesium alloys with spherical particles have unique advantages in specific applications, such as good fluidity, strong filling capacity and easy processing.

[0003] For example, the patent document with the prior art announcement number CN219357938U discloses a spherical particle forming machine for tin and tin alloys, which relates to the field of granulation equipment for metal liquid phase forming, and includes a spheroidizing molder, a dropper arranged on the spheroidizing molder and a melting furnace arranged on the dropper, the upper end surface of the spheroidizing molder is provided with a feed port, the spheroidizing molder is provided with a accommodating cavity, and also includes a water supply box and a cooling box arranged on the water supply box, the spheroidizing molder is provided with a water cooling pipe, the water cooling pipe is provided with a water inlet, the water supply box is provided with a connecting pipe, the water cooling pipe is provided with a water outlet, the connecting pipe is provided with a water pump, the cooling box is located above the water supply box, the bottom of the cooling box is provided with a through hole, the cooling box is provided with an adjusting mechanism, water is transported to the water cooling pipe through the connecting pipe to cool the mixed oil, and the energy consumption of the water pump is smaller than that of the compressor, thereby reducing the energy consumption required for cooling the mixed oil.

[0004] Although the above-mentioned prior art is designed with a cooling box to effectively cool the mixed oil, there is a significant shortcoming in the actual application scenario. Specifically, after the material released by the dropper passes through the porous screen, it directly contacts the mixed oil below for shaping. However, during this falling process, the material may fall into the mixed oil in a variety of different postures or angles, which leads to different shaping effects of the material in the mixed oil, and thus makes the overall forming rate low. This inconsistent falling posture not only affects the uniformity and regularity of the spherical particles, but may also lead to a decrease in production efficiency and fluctuations in product quality. To this end, the present application proposes a magnesium alloy spherical particle forming device and a forming process thereof. Summary of the invention

[0015] The present invention also provides a magnesium alloy spherical particle forming process, comprising the following steps: S1. When in use, the metal powder is first cleaned and impurity-free and then poured into the hopper, and the magnesium alloy powder raw material in the hopper is poured into the inside of the electric heating feed pipe, and then the powder raw material is heated and transported to the inside of the pressurized box, and passes through the forming orifice plate to form; S2, at the same time, the inside of the air ring is inflated, and the pre-cooling pipe and the screen plate are exhausted alternately under the operation of the regulating component, and at the same time, the push plate pushes the unscreened materials under the action of the driving component; S3, the screened material falls through the screen plate and enters the interior of the centrifugal cylinder for shaping; S4. When the spherical particles fall into the receiving box, they will first hit the buffer rubber pad for buffering. Under the operation of the air source component, the air outlet holes on the rolling plate will exhaust air to cool and remove dust from the materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The metal powder is quickly heated to a molten state by the electric heating wire in the electric heating feed pipe, and is evenly transported to the pressurized box by the feed blade. The cylinder drives the pressing plate to press down, and the molten material is extruded through the forming orifice plate to form a preliminary spherical particle shape. The whole process is efficient and continuous, which significantly improves production efficiency. The cutting blade on the hollow rotating rod rotates under the drive of the second motor to accurately cut the material passing through the forming orifice plate to ensure that the size and shape of each spherical particle meet the requirements. The cutting process is stable and reliable, reducing material waste and the production of defective products. The air pump delivers gas to the air sleeve ring through the air pipe, and the adjustment component intelligently changes the direction of the air flow according to the rotation state of the hollow rotating rod. When the cutting blade cuts the material, the air flow is directed to the inside of the hollow rotating rod to perform the initial cooling of the just cut material to prevent it from re-bonding together. When the cutting is completed, the air flow is directed to the inside of the sieve plate to perform secondary cooling on the material passing through the sieve plate to prepare for subsequent shaping. This intelligent cooling method not only improves the cooling efficiency of the material, but also ensures the quality and stability of the spherical particles. The screen plate screens the cut materials to ensure that only qualified spherical particles pass through. The drive assembly uses airflow to drive the push plate to move, and the unqualified materials that have not passed through the screen plate are cleaned to one side of the pressurized box for storage. This automatic screening and cleaning method reduces manual intervention and improves production efficiency and product quality.

[0017] The centrifugal cylinder provides further shaping for the spherical particles. Through the centrifugal force generated by the rotation, the spherical particles gradually form a more regular sphere in the rolling, friction and collision, which improves the roundness and surface quality of the product. At the same time, the dual screening mechanism of the centrifugal cylinder and the screen plate ensures that only spherical particles that meet the standards can be discharged, effectively preventing oversized or undersized particles from being mixed into the finished product, further improving the product quality. The buffer rubber pad inside the receiving box can effectively catch the spherical particles falling from the centrifugal cylinder, provide preliminary buffering for them, and reduce the collision damage between particles. The compression deformation of the buffer rubber pad drives the piston spring rod to slide in the cylinder, and then pushes the gas to be transported to the rolling plate through the connecting pipe, and sprayed out through the air outlet, and the spherical particles are finally cooled and dusted. This design not only improves the cooling efficiency, but also ensures the cleanliness of the surface of the spherical particles, which provides convenience for subsequent packaging and transportation. The setting of the one-way air intake valve ensures that the external gas can smoothly enter the cylinder, while the gas in the cylinder cannot be discharged through the one-way air intake valve, realizing the one-way flow and recycling of the gas.

The bottom of the electric heating feeding pipe 101 is provided with a first motor 102 for driving the feeding blade 103 to rotate. The internal structure of the electric heating feeding pipe 101 is provided with an electric heating wire which can heat the metal powder in the electric heating feeding pipe 101 to a molten state, and transport it to the inside of the pressurizing box 104 through the feeding blade 103. As the driving cylinder 105 runs, the pressing plate 106 is operated to move downward and pressurize the molten material to pass through the forming orifice plate 107, and the sieve plate 108 can be screened, and the metal powder can be cleaned and impurity-removed. Common cleaning methods include solvent cleaning, ultrasonic cleaning, etc. By cleaning, the oil and impurities on the surface of the powder can be removed, the purity and surface activity of the powder can be improved, and then the metal powder can be placed in the hopper 100.

[0022] See also Figure 3 , Figure 5 as well as Figure 6 , and also includes a hollow rotating rod 200, which is arranged inside the pressurized box 104 and has a plurality of cutting blades 201 fixedly connected to the top thereof for cutting materials, and a plurality of pre-cooling tubes 202 are evenly connected to the inside of the hollow rotating rod 200, and an air sleeve ring 204 is fixedly connected to the outer surface of the sieve plate 108, and an adjusting component for changing the direction of airflow is arranged inside the air sleeve ring 204, and the direction of airflow can be changed by setting the adjusting component, thereby realizing multiple cooling and improving subsequent shaping, wherein the cutting blade 201 can cut the material passing through the forming orifice plate 107 to separate the spherical particles.

[0023] See also Figure 7 , Figure 8 as well as Fig. 9The adjusting assembly includes a rotating shaft 208 rotatably connected to the top of the gas sleeve ring 204, a trigger plate 209 is fixedly connected to the top of the rotating shaft 208, a pull handle 210 is fixedly connected to the bottom of the rotating shaft 208, the gas sleeve ring 204 is internally rotatably connected to a lever 212 having one end rotatably connected to the pull handle 210, a torsion spring is sleeved at the connection between the gas sleeve ring 204 and the lever 212, a double-headed piston rod 211 rotatably connected to the bottom of the lever 212 is arranged inside the gas sleeve ring 204, one end of the gas sleeve ring 204 is connected to a side pipe 213, an air pump 206 is fixedly connected to the bottom of the pressurizing box 104, and an output end of the air pump 206 is connected to an air supply pipe 207 connected to the gas sleeve ring 204, by setting the air pump 206, air can be continuously supplied to the gas sleeve ring 204, and when the cutting blade 201 is pressed against the material When cutting, the regulating component operates to direct the gas to the inside of the hollow rotating rod 200, so that the airflow blows toward the material just cut, and performs the initial cooling of the material, thereby preventing it from sticking together again. When the cutting is completed, the cutting blade 201 will be stationary, and then the regulating component will direct the gas in the gas ring 204 to the inside of the sieve plate 108, so that the material passing through the sieve plate 108 is disturbed by the airflow again for subsequent cooling, wherein the lever 212 is initially set under the action of the torsion spring so that one end of the double-headed piston rod 211 is away from the inside of the side tube 213, and the other end of the double-headed piston rod 211 is placed inside the gas ring 204, so that the gas in the gas ring 204 cannot enter the inside of the hollow rotating rod 200, but the gas in the gas ring 204 enters the inside of the side tube 213.

[0024] Among them, the outer surface of the hollow rotating rod 200 is fixedly connected with an arc-shaped piece 205 that can interfere with the trigger piece 209, and the bottom of the pressurizing box 104 is fixedly connected with a second motor 203 that drives the hollow rotating rod 200 to rotate. A connecting groove 218 is opened on the outer surface of the hollow rotating rod 200. The arc-shaped piece 205 can follow the rotation of the hollow rotating rod 200 and drive the adjustment component to operate so that the gas in the air sleeve ring 204 is transported to the inside of the hollow rotating rod 200.

[0025] See also Fig. 9 , Fig.10 as well as Fig.11A push plate 217 is provided above the sieve plate 108, and a driving assembly for driving the push plate 217 to move is provided inside the sieve plate 108, and the driving assembly includes a blade 214 rotatably connected to the inside of the sieve plate 108, and one end of the side tube 213 extends to one side of the blade 214, and a rotating ring 215 slidably connected to the sieve plate 108 is fixedly connected to the bottom of the push plate 217, and a plurality of connecting pieces 216 that can contact the blade 214 are fixedly connected to the bottom of the rotating ring 215. As the gas enters the interior of the sieve plate 108, the blade 214 rotates and pushes the rotating ring 215 to rotate, thereby driving the push plate 217 to move continuously, so that the unqualified materials that have not passed through the sieve plate 108 are swept away, so that they are cleaned to one side of the pressurized box 104 for storage.

[0026] It is worth mentioning that the air pump 206 runs for a long time, while the second motor 203 runs intermittently. Whenever the second motor 203 runs to drive the hollow rotating rod 200 to rotate, its arc-shaped plate 205 will push the trigger plate 209 to move and drive the adjustment component, so that the gas in the air ring 204 is guided to the inside of the hollow rotating rod 200 to pre-cool the cut material. When the hollow rotating rod 200 is stationary, the gas in the air ring 204 will be transported to the inside of the screen plate 108 to perform secondary cooling on the screened material, which allows the same batch of materials to be cooled twice. The initial cooling can prevent the cut materials from sticking together again, and the second cooling can further reduce the temperature to prepare for subsequent shaping while driving the push plate 217 to move.

[0027] Specifically, when in use, the magnesium alloy powder raw material in the hopper 100 is first poured into the interior of the electrically heated feeding pipe 101, and then the first motor 102 is started to drive the feeding blade 103 to rotate, so that the powder raw material is heated and at the same time conveyed to the interior of the pressurizing box 104 through the feeding blade 103, and then the cylinder 105 is driven to drive the pressing plate 106 to move downward so that the molten material passes through the forming orifice plate 107 to form, and then the second motor 203 is driven to rotate to drive the hollow rotating rod 200 to rotate so that the cutting blade 201 rotates to cut the raw material passing through the forming orifice plate 107, and the cut material will be screened by the sieve plate 108, and at the same time, the air pump 206 is turned on to convey it to the interior of the air sleeve ring 204 through the air pipe 207, wherein when the hollow rotating rod 200 is stationary, the gas in the air sleeve ring 204 will be conveyed through the side pipe 213. The delivery blade 214 rotates, so that the blade 214 continuously hits the connecting piece 216, thereby driving the rotating ring 215 to rotate and then driving the push plate 217 to rotate, so that the push plate 217 pushes the unscreened material, and at the same time, the airflow will also flow through the inside of the sieve plate 108 to cool the material passing through the sieve plate 108. At the same time, when the hollow rotating rod 200 rotates to transmit the cutting blade 201, the arc-shaped piece 205 will rotate with the hollow rotating rod 200 to push the triggering piece 209 to move, so that the handle 210 pushes one end of the lever 212 to move, thereby changing one end of the double-headed piston rod 211 to be close to the side tube 213, so that the gas in the air ring 204 passes through the air ring 204 and passes through the connecting groove 218 to irritate the inside of the hollow rotating rod 200, and then the gas is ejected through the air ring 204 to preliminarily cool the just-cut material to prevent it from sticking.

[0028] In summary, the metal powder is quickly heated to a molten state by the electric heating wire in the electric heating feed pipe 101, and is evenly transported to the pressurized box 104 by the feed blade 103. The cylinder 105 drives the pressing sheet 106 to press down, and the molten material is extruded through the forming orifice plate 107 to form a preliminary spherical particle shape. The whole process is efficient and continuous, which significantly improves the production efficiency. The cutting blade 201 on the hollow rotating rod 200 rotates under the drive of the second motor 203, and the material passing through the forming orifice plate 107 is accurately cut to ensure that the size and shape of each spherical particle meet the requirements. The cutting process is stable and reliable, reducing material waste and the generation of defective products. The air pump 206 delivers gas to the air sleeve ring 204 through the air pipe 207, and the regulating component intelligently changes the direction of the airflow according to the rotation state of the hollow rotating rod 200. When the cutting blade 201 cuts the material, the airflow is directed to the inside of the hollow rotating rod 200, and the material just cut is cooled for the first time to prevent it from sticking together again. When the cutting is completed, the airflow is directed to the inside of the sieve plate 108 to perform secondary cooling on the material passing through the sieve plate 108 in preparation for subsequent shaping. This intelligent cooling method not only improves the cooling efficiency of the material, but also ensures the quality and stability of the spherical particles. The sieve plate 108 screens the cut material to ensure that only qualified spherical particles pass through. The drive assembly uses the airflow to drive the push plate 217 to move, and cleans the unqualified materials that have not passed through the sieve plate 108 to one side of the pressurized box 104 for storage. This automatic screening and cleaning method reduces manual intervention and improves production efficiency and product quality.

[0029] Example 2: Please refer to Fig.12 , Fig.13 as well as Fig.14 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a magnesium alloy spherical particle forming device, which also includes a centrifugal cylinder 300, which is used to shape the formed magnesium alloy spherical particles. The bottom of the pressurizing box 104 is fixedly connected with a bracket 301 for supporting the centrifugal cylinder 300, and the bottom of the bracket 301 is fixedly connected with a third motor 302 for driving the centrifugal cylinder 300 to rotate. One side of the bracket 301 is fixedly connected to a limiting rod 303. By setting the centrifugal cylinder 300, the spherical particles can be caught and rotated under the drive of the third motor 302. During the rolling, friction and collision process of the spherical particles on the centrifugal cylinder 300, a sphere is gradually formed and then discharged under the action of centrifugal force. At the same time, the screen plate 108 can screen out oversized spherical particles, and the centrifugal cylinder 300 can screen out oversized spherical particles, so that the spherical particles that meet the standards are discharged.

[0030] The invention also includes a material receiving box 400, in which a buffer rubber pad 401 for collecting magnesium alloy spherical particles is arranged, and a rolling plate 403 is arranged inside the material receiving box 400, a plurality of exhaust holes 404 are opened inside the rolling plate 403, and a gas source component for supplying gas to the gas outlet holes 404 is arranged at the bottom of the buffer rubber pad 401, and the gas source component includes a plurality of gas cylinders 405 fixedly connected to the inside of the material receiving box 400, the tops of the plurality of gas cylinders 405 are slidably connected with piston spring rods 407 adapted thereto, and the tops of the plurality of piston spring rods 407 are fixedly connected to the bottom of the buffer rubber pad 401, and one side of the plurality of gas cylinders 405 is connected with a connecting pipe 406 connected to the rolling plate 403, wherein the buffer rubber pad 401 can catch the spherical particles to buffer them, and in cooperation with the gas source component, the spherical particles can be subjected to a final cooling treatment, and dust on their surface can be treated at the same time.

[0031] Among them, one side of the multiple air cylinders 405 is fixedly connected with a one-way air intake valve 408, the buffer rubber pad 401 and the rolling plate 403 are both constructed as inclined surfaces, and a discharge trough 402 is opened on one side of the material receiving box 400. The setting of the inclined surface can guide the movement of the spherical particles so that they can be discharged smoothly, and the one-way air intake valve 408 allows external gas to enter the air cylinder 405, while the gas in the air cylinder 405 cannot be discharged through the one-way air intake valve 408.

[0032] Specifically, the sieved material falls through the sieve plate 108 and enters the interior of the centrifugal cylinder 300. Turning on the third motor 302 can drive the centrifugal cylinder 300 to rotate, so that the material in the centrifugal cylinder 300 generates centrifugal force, so that the material continuously rolls to form a sphere, and with the centrifugal force, the material separates from the centrifugal cylinder 300 and falls into the interior of the receiving box 400. The spherical particles falling into the receiving box 400 will first resist the buffer rubber pad 401 for buffering. At this time, the buffer rubber pad 401 is impacted and will squeeze the piston end of the piston spring rod 407 to slide inside the air cylinder 405, thereby pushing the gas in the air cylinder 405 to be transported to the interior of the rolling plate 403 through the connecting pipe 406, and finally ejected through a plurality of air outlet holes 404, so as to finally cool and remove dust from the spherical particles on the rolling plate 403.

[0033] In summary, the centrifugal cylinder 300 is provided to further shape the spherical particles. Through the centrifugal force generated by the rotation, the spherical particles gradually form a more regular sphere during rolling, friction and collision, thereby improving the roundness and surface quality of the product. At the same time, the dual screening mechanism of the centrifugal cylinder 300 and the screen plate 108 ensures that only spherical particles that meet the standards can be discharged, effectively preventing oversized or undersized particles from being mixed into the finished product, further improving the product quality. The buffer rubber pad 401 inside the receiving box 400 can effectively catch the spherical particles falling from the centrifugal cylinder 300, provide preliminary buffering, and reduce collision damage between particles. The compression deformation of the buffer rubber pad 401 drives the piston spring rod 407 to slide in the air cylinder 405, thereby pushing the gas to be transported to the rolling plate 403 through the connecting pipe 406, and ejected through the air outlet 404, so as to perform the final cooling and dust removal treatment on the spherical particles. This design not only improves the cooling efficiency, but also ensures the cleanliness of the surface of the spherical particles, providing convenience for subsequent packaging and transportation. The setting of the one-way air inlet valve 408 ensures that external gas can smoothly enter the air cylinder 405, while the gas in the air cylinder 405 cannot be discharged through the one-way air inlet valve 408, thereby realizing the one-way flow and recycling of the gas.

[0034] Example 3: Please refer to Figures 1 to 14 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a magnesium alloy spherical particle forming process, comprising the following steps: S1. When in use, first pour the magnesium alloy powder raw material in the hopper 100 into the inside of the electrically heated feeding pipe 101, then start the first motor 102 to drive the feeding blade 103 to rotate, so that the powder raw material is heated and at the same time conveyed to the inside of the pressurizing box 104 through the feeding blade 103, then drive the cylinder 105 to drive the pressing sheet 106 to move downward so that the molten material passes through the forming orifice plate 107 to form, then drive the second motor 203 to rotate and drive the hollow rotating rod 200 to rotate so that the cutting blade 201 rotates to cut the raw material passing through the forming orifice plate 107, and the cut material will be screened through the sieve plate 108; S2, at the same time, start the air pump 206 and deliver the gas to the inside of the air ring 204 through the air delivery pipe 207, wherein when the hollow rotating rod 200 is stationary, the gas in the air ring 204 will pass through the side pipe 213 to deliver the blade 214 to rotate, so that the blade 214 continuously hits the connecting piece 216, thereby driving the rotating ring 215 to rotate and then driving the push plate 217 to rotate, so that the push plate 217 pushes the unscreened material, and at the same time, the airflow will also flow through the inside of the sieve plate 108 to cool the material passing through the sieve plate 108, and at the same time, the hollow When the rotating rod 200 rotates to transmit the cutting blade 201, the arc-shaped blade 205 will rotate along with the hollow rotating rod 200 and push the trigger blade 209 to move, so that the pull handle 210 pushes one end of the lever 212 to move, thereby changing one end of the double-headed piston rod 211 to be close to the side tube 213, so that the gas in the gas ring 204 passes through the gas ring 204 and the connecting groove 218 to irritate the inside of the hollow rotating rod 200, and then the gas is ejected through the gas ring 204 to preliminarily cool the material just cut to prevent it from sticking; S3, the screened material falls through the screen plate 108 and enters the interior of the centrifugal cylinder 300, and the third motor 302 is turned on to drive the centrifugal cylinder 300 to rotate so that the material in the centrifugal cylinder 300 generates centrifugal force, so that the material continuously rolls to form a spherical shape, and the material falls out of the centrifugal cylinder 300 and falls into the interior of the material receiving box 400 due to the centrifugal force; S4. When the spherical particles fall into the collecting box 400, they will first hit the buffer rubber pad 401 for buffering. At this time, the buffer rubber pad 401 will be impacted to squeeze the piston end of the piston spring rod 407 to slide inside the air cylinder 405, thereby pushing the gas in the air cylinder 405 to be transported to the inside of the rolling plate 403 through the connecting pipe 406, and finally sprayed out through multiple air outlet holes 404, so as to finally cool and remove dust from the spherical particles on the rolling plate 403.

[0035] In summary, the magnesium alloy powder raw material in the hopper 100 is continuously fed in through the electrically heated feed pipe 101, and the feed blade 103 driven by the first motor 102 not only heats the raw material but also transports it to the pressurizing box 104, realizing efficient and continuous raw material supply. The molten raw material in the pressurizing box 104 is formed into a preliminary shape through the forming orifice plate 107, and then the hollow rotating rod 200 driven by the second motor 203 drives the cutting blade 201 to rotate, realizing automatic cutting and improving production efficiency. The shape formed by the molten raw material through the forming orifice plate 107 is precise, and the cut material is screened by the sieve plate 108 to ensure the consistency of the size and shape of the spherical particles. The air pump 206 delivers gas to the air sleeve ring 204 through the air pipe 207. When the cutting blade 201 is working, the gas is ejected through the connecting groove 218 to preliminarily cool the material just cut, effectively avoiding adhesion and improving the quality of the finished product. When the hollow rotating rod 200 is stationary, the gas in the air sleeve ring 204 drives the blade 214 to rotate through the side pipe 213, and then pushes the unscreened material through the connecting piece 216, the rotating ring 215 and the push plate 217, so as to achieve full utilization and efficient processing of the material. After cooling and pushing the material, part of the gas used in the process can be recycled, reducing energy consumption and environmental pollution. When the spherical particles fall into the receiving box 400, they are buffered by the buffer rubber pad 401, and at the same time, the piston spring rod 407 is squeezed to push the gas in the air cylinder 405 through the connecting pipe 406 to the rolling plate 403, and finally ejected through the air outlet 404, so as to finally cool and remove dust from the spherical particles, which is both energy-saving and environmentally friendly.
