Description

Technical Field

[0001] This invention relates to the field of transmission device technology, specifically to a transmission device for processing die-cast aluminum parts. Background Technology

[0002] Die-cast aluminum parts are various aluminum structural components obtained by injecting molten aluminum alloy into a mold cavity and cooling it to form a solid shape. They are widely used in machinery, automobiles, electronics and other fields, and are characterized by lightweight, high strength and high forming precision.

[0003] For example, patent document CN118419573A discloses a conveying device for die-cast aluminum parts, including a stopping component and a detection component. The stopping component includes a conveyor table, baffles disposed on both sides of the conveyor table, a cleaning component connected to the baffles, and a shielding component connected to the cleaning component. The stopping component can position the die-cast parts on the conveyor table and clean the conveyor belt during movement to ensure that the bottom of the die-cast parts fits as close to the conveyor table as possible during transport. Simultaneously, the detection component can detect the height of the upper end of the die-cast parts, screening out aluminum parts that are not die-cast to the required height.

[0004] The above-mentioned technical solution uses a simple linear conveyor table for transport. The exposed workpiece is transported and relies on natural heat dissipation, which has low cooling efficiency. This makes the high-temperature die-cast aluminum workpieces prone to rapid cooling cracking and temperature difference deformation during transport. Therefore, it is urgent to design a transport device for processing die-cast aluminum parts to solve the above problems. Summary of the Invention

[0008] As a further improvement to this solution, the cross-section of the U-shaped jet frame is U-shaped, and jet heads are evenly arranged on the inner side of the U-shaped jet frame.

[0009] As a further improvement to this solution, the jet heads are arranged at equal intervals on the inner side of the U-shaped jet frame, and each jet head is equipped with a baffle net inside.

[0010] As a further step of this solution, a second electric push rod is fixed to the outside of the secondary gradient cooling box, and the output end of the second electric push rod extends into the interior of the secondary gradient cooling box where a pusher plate is fixed.

[0012] As a further step in this solution, the height of the auxiliary transfer feeding platform when not in use is slightly lower than the plane of the turntable, and the rotation direction of the roller is set to rotate towards the longitudinal conveyor belt.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problem of the limited heat dissipation and transport structure in existing technologies, the following solution is disclosed, as detailed below. Figures 1-10As shown, the conveying device for processing die-cast aluminum parts provided in this application includes a two-stage gradient cooling box 1, a longitudinal conveyor belt 3, and a transverse conveyor belt 4. The longitudinal conveyor belt 3 and the transverse conveyor belt 4 are respectively connected to both sides of the two-stage gradient cooling box 1. A three-stage ambient temperature stabilization box 2 and a one-stage preheating buffer box 5 are respectively fixed to the outer sides of the longitudinal conveyor belt 3 and the transverse conveyor belt 4. One end of both the three-stage ambient temperature stabilization box 2 and the one-stage preheating buffer box 5 is fixedly connected to the two-stage gradient cooling box 1. An air-cooled chamber 7 is provided inside the two-stage gradient cooling box 1, and a hollow rotating shaft 11 is rotatably connected to the bottom of the air-cooled chamber 7. A turntable 9 is fixed to the top of the secondary gradient cooling box 1. A side operating seat 19 is fixed to one side of the secondary gradient cooling box 1. A lower operating groove 24 is opened between the bottom ends of the secondary gradient cooling box 1 and the side operating seat 19. An upper operating groove 16 is opened between the top ends of the secondary gradient cooling box 1 and the side operating seat 19. A side operating groove 28 is provided inside the side operating seat 19. A first rotating shaft 18 and a second rotating shaft 23 are rotatably connected to the two ends inside the side operating groove 28, respectively. A second bevel gear 22 is fixed to the inner side of both the first rotating shaft 18 and the second rotating shaft 23. A motor 20 is fixed to one side of the side operating seat 19, and the motor 20 outputs... A first bevel gear 21 is fixed inside the side operating slot 28 extending from the output shaft. The first bevel gear 21 and the second bevel gear 22 are meshed together. The top of the secondary gradient cooling box 1 is rotatably connected to a U-shaped jet frame 8 through a vent pipe 25. The temperature range of the tertiary ambient temperature stabilization box 2 is 30-60℃, the temperature range of the secondary gradient cooling box 1 is 100-200℃, and the temperature range of the primary preheating buffer box 5 is 200-280℃. The U-shaped jet frame 8 has a U-shaped cross-section, and jet heads 26 are evenly arranged on the inner side of the U-shaped jet frame 8 at equal intervals. The distribution includes a baffle mesh inside the jet head 26, the bottom ends of the second rotating shaft 23 and the hollow rotating shaft 11 extending into the interior of the lower operating slot 24, the outer sides of the second rotating shaft 23 and the hollow rotating shaft 11 being connected to a transmission belt via pulleys, the top ends of the first rotating shaft 18 and the vent pipe 25 extending into the interior of the upper operating slot 16, the top end of the interior of the secondary gradient cooling box 1 being fixed with an air inlet pipe 6, and the bottom end of the air inlet pipe 6 being connected to the vent pipe 25 via a straight-through sealed rotary joint 17, the transmission surface of the transverse conveyor belt 4 being coated with a composite Teflon high-temperature resistant coating, and the transmission surface of the longitudinal conveyor belt 3 being provided with vent holes.

[0021] In this embodiment, the high-temperature aluminum parts after die casting are first conveyed to the transverse conveyor belt 4 and then preheated in the first-stage preheating buffer box 5. The temperature range of the box is 200-280℃, which provides initial temperature buffering for the parts to prevent them from directly entering the cooling process and causing rapid cooling cracking. At the same time, the temperature of the parts is kept uniform. The composite Teflon high-temperature resistant coating on the transmission surface of the transverse conveyor belt 4 can effectively resist the high-temperature corrosion of the parts and prevent the parts from sticking to the conveyor belt. The preheated and buffered components are conveyed by the transverse conveyor belt 4 to the secondary gradient cooling box 1, and fall from the end of the transverse conveyor belt 4 onto the turntable 9 inside the air-cooling chamber 7. The motor 20 on one side of the start-up side operating seat 19 is activated. The output shaft of the motor 20 drives the first bevel gear 21 to rotate, which in turn drives the first rotating shaft 18 and the second rotating shaft 23 to rotate synchronously. The second rotating shaft 23, through a pulley and transmission belt in the lower operating groove 24, drives the hollow rotating shaft 11 to rotate, thereby driving the turntable 9 at the top to rotate. Simultaneously, the first rotating shaft 18 extends into the upper operating groove 16, driving the vent pipe 25 to rotate, thus driving the U-shaped jet frame 8 to rotate synchronously, allowing air to enter. Pipe 6 is connected to vent pipe 25 via a straight-through sealed rotary joint 17 to ensure stable gas delivery without affecting the rotation of vent pipe 25. Cooling gas enters U-shaped jet frame 8 through inlet pipe 6 and vent pipe 25, and is then evenly sprayed onto the parts on turntable 9 through jet nozzles 26 arranged at equal intervals on its inner side. The temperature range of the secondary gradient cooling box 1 is controlled between 100-200℃. Through the synchronous rotation of U-shaped jet frame 8 and turntable 9, the parts are evenly cooled in a gradient temperature environment, avoiding deformation caused by excessively rapid local cooling. The baffle inside the jet nozzle 26 can filter impurities in the cooling gas to prevent impurities from adhering to the surface of the parts and affecting product quality. After being cooled by gradient air, the parts are transferred to the longitudinal conveyor belt 3 via the pusher plate 29. The temperature range of the three-stage room temperature stabilization box 2 on the outside is 30-60℃ to stabilize the parts at room temperature and slowly reduce the temperature of the parts. At the same time, the ventilation holes on the transmission surface of the longitudinal conveyor belt 3 allow the bottom of the parts to fully contact the air, ensuring that the temperature of the upper and lower surfaces of the parts is uniform, further improving the shaping effect, and finally completing the entire transmission and cooling process. In summary, the three-stage temperature control structure forms a continuous temperature gradient, effectively preventing high-temperature parts from cracking due to rapid cooling and deformation caused by uneven cooling. This effectively improves the dimensional stability and yield of die-cast aluminum parts. At the same time, the synchronous rotation of the U-shaped jet frame 8 and the turntable 9 enables multi-faceted air cooling of parts, further improving cooling uniformity. Furthermore, the single drive source simplifies the drive structure, reducing equipment failure rate and energy consumption. The transverse conveyor belt 4 and the longitudinal conveyor belt 3 are respectively connected to both sides of the secondary gradient cooling box 1. Combined with the integrated design of the three-stage temperature control box, the entire process of parts from preheating to shaping is automated, reducing manual intervention and improving production efficiency.

[0022] Example 2: This example differs from Example 1 by incorporating a lifting and pushing structure to facilitate the material being pushed onto the longitudinal conveyor belt 3 after secondary cooling. Specifically, as shown below... Figure 1 , Figure 3 and Figure 10As shown, a second electric push rod 27 is fixed to the outside of the secondary gradient cooling box 1, and the output end of the second electric push rod 27 extends into the interior of the secondary gradient cooling box 1 and is fixed with a push plate 29. A storage groove 15 is provided at the top of the turntable 9. A first electric push rod 12 is fixed to one side of the bottom of the lower operating groove 24 by a bracket. The output end of the first electric push rod 12 passes through the hollow rotating shaft 11 and extends into the interior of the storage groove 15 and is fixed with an auxiliary transfer feeding platform 10. The interior of the auxiliary transfer feeding platform 10 is evenly provided with grooves 13, and each groove 13 is connected with a roller 14. When not in use, the height of the auxiliary transfer feeding platform 10 is slightly lower than the plane of the turntable 9. The rotation direction of the roller 14 is set to rotate towards the longitudinal conveyor belt 3.

[0023] In this embodiment, during use, after the component completes gradient cooling on the turntable 9, the first electric push rod 12 is activated. The output end of the first electric push rod 12 passes through the hollow rotating shaft 11, extends into the storage groove 15, and pushes the auxiliary transfer feeding platform 10 upward until the height of the auxiliary transfer feeding platform 10 is slightly higher than the plane of the turntable 9, lifting the component. The roller 14 inside the auxiliary transfer feeding platform 10 rotates towards the longitudinal conveyor belt 3. After the component is lifted onto the auxiliary transfer feeding platform 10, the second electric push rod 27 outside the secondary gradient cooling box 1 is activated. The output end of the second electric push rod 27 pushes the push plate 29. With the assistance of the roller 14, the component can smoothly slide towards the longitudinal conveyor belt 3.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
