DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] When implementing: Figure 1-8 As shown, a forming die for aluminum profile processing comprises: a die base 1, a supporting frame 2 is arranged at the upper end of the die base 1; an auxiliary shaping mechanism 3, the auxiliary shaping mechanism 3 is arranged on the inner side of the die base 1, and the surface of the auxiliary shaping mechanism 3 extends to the upper side of the die base 1; wherein the auxiliary shaping mechanism 3 comprises a metal shaping component 31 arranged on the inner side of the die base 1, a heat preservation component 32 is arranged on one side of the metal shaping component 31, the heat preservation component 32 is located on the inner side of the die base 1, the surface of the metal shaping component 31 penetrates to the outside of the die base 1 and is connected to a profile shaping component 33, and the profile shaping component 33 is arranged above the die base 1;

[0028] like Figure 1-Figure 8As shown, the metal shaping component 31 includes a first die head 311 arranged on the inner side of the die base 1, the upper end of the first die head 311 is fixedly connected with a vortex tube 312, the interior of the first die head 311 is provided with a first inner groove 313, the inner wall of the first inner groove 313 is fixedly connected with a first metal ring 314, the interior of the first inner groove 313 is connected with an air intake cooling pipe 317, the other end of the air intake cooling pipe 317 is connected with the cold air end of the vortex tube 312, the interior of the first metal ring 314 is provided with an exhaust cooling pipe 318, the other end of the exhaust cooling pipe 318 passes through the outside of the first die head 311, the inner wall of the first inner groove 313 is fixedly connected with a cold water copper pipe 315, both ends of the cold water copper pipe 315 pass through the outside of the first die head 311, the inner wall of the first metal ring 314 is fixedly connected with a spiral metal ring 316, and the spiral metal ring 316 is fixedly connected to the inner wall of the first inner groove 313. The upper end of the vortex tube 312 is externally connected to an air intake pipe, {wherein the air intake speed of the air intake pipe is mainly based on the use requirements of the vortex tube 312, and can also be appropriately adjusted according to the on-site use environment}, when the vortex tube 312 guides the high-speed incoming gas to the outside through the air intake cold pipe 317 and the air intake heat pipe 326, the air intake cold pipe 317 can introduce the low-temperature gas into the first inner tank 313, and at the same time, the cold water copper pipe 315 can cool the mold discharge end of the first die head 311, and at the same time, the internal liquid of the cold water copper pipe 315 absorbs a large amount of heat after heat exchange. At this time, the low-temperature gas introduced into the first inner tank 313 through the air intake cold pipe 317 can take away the heat absorbed by the cold water copper pipe 315, and at the same time, the liquid inside the cold water copper pipe 315 is assisted to cool down;

[0029] At the same time, when the air inlet cooling pipe 317 introduces the gas to the outer edge of the first metal ring 314, the gas is injected into the first metal ring 314 through the gap between the other side of the first metal ring 314 and the first inner groove 313. The gas temperature is assisted by the spiral metal ring 316 to cool down the cold water copper tube 315, and the spiral metal ring 316 can also be cooled. At this time, the spiral metal ring 316 performs a secondary cooling operation on the discharge end, thereby improving the cooling effect on the discharge and reducing the deformation of the aluminum metal profile at the discharge end.

[0030] The insulation component 32 includes a second die head 321 arranged on one side of the first die head 311, and a second inner groove 322 is opened inside the second die head 321, and the upper end of the second inner groove 322 is connected to the air intake heat pipe 326, and the other end of the air intake heat pipe 326 is connected to the hot air end of the vortex tube 312, and the inner wall of the second inner groove 322 is fixedly connected to a second metal ring 323, and a notch 324 is opened on the side of the second metal ring 323, and the inner wall of the second inner groove 322 is fixedly connected to a supporting heat conduction plate 325, and the upper end of the supporting heat conduction plate 325 passes through the notch 324 and extends to the outside of the second metal ring 323. When the gas enters the air intake heat pipe 326, the gas with a higher temperature is injected into the second inner groove 322 through the air intake heat pipe 326. The gas in the second inner groove 322 is located outside the second metal ring 323. At this time, the high-temperature gas with a temperature relatively high to that of the first inner groove 313 enters the inner side of the second metal ring 323 through the opening 324, thereby forming an auxiliary heating effect on the supporting heat conducting plate 325. At the same time, the setting of the supporting heat conducting plate 325 allows the high-temperature gas to flow more evenly inside the second metal ring 323, thereby improving the fluidity of this part of the aluminum metal, and then the gas inside the second metal ring 323 is discharged to the outside through the exhaust pipe at the lower end.

[0031] like Figure 1 , Figure 7 and Figure 8 As shown, the profile shaping assembly 33 includes a fixed frame 331 fixedly connected to the upper end of the mold base 1, the inner side of the fixed frame 331 is rotatably connected to a rotating seat 332, the upper end of the rotating seat 332 is fixedly connected to a nozzle 333, the lower end of the rotating seat 332 is connected to the other end of the exhaust cooling pipe 318, a cross bar 334 is fixedly connected to one side of the rotating seat 332, a coil spring 336 is fixedly connected to the surface of the cross bar 334, the coil spring 336 is fixedly connected to the surface of the fixed frame 331, and the other end of the cross bar 334 is fixedly connected to a dial plate 335. There are multiple supporting rollers on the upper end of the supporting frame 2, and the rotating shaft of one of the supporting rollers extends outward and is fixedly connected to a dial plate 335. When the aluminum profile is extruded, the supporting roller is driven to rotate, and then the rotating shaft is driven to rotate. At this time, the dial plate 335 on the rotating shaft reciprocates the dial plate 335 at the end of the cross bar 334. At this time, the cross bar 334 drives the rotating seat 332 to swing back and forth under the action of the winding spring 336, and then the cold air discharged from the exhaust cooling pipe 318 is blown to the upper discharge aluminum profile through the nozzle 333, thereby reducing the high temperature of the extruded profile and the easy deformation.

[0032] When the utility model is in use, the aluminum metal is located inside the heat preservation component 32 and moves to the metal shaping component 31 for extrusion. The upper end of the vortex tube 312 injects a high-speed airflow through the air intake cooling pipe 317 to discharge cold air and the air intake heat pipe 326 to discharge hot air. The air intake cooling pipe 317 introduces low-temperature gas into the first inner groove 313. The cold water copper pipe 315 cools the die discharge end of the first die head 311. The air intake cooling pipe 317 injects gas into the first metal ring 314. Through the spiral spiral The metal ring 316 conducts the gas to the surface of the extruded material. The extruded aluminum profile will be supported by the support frame 2. One of the supporting rollers will drive the rotating shaft to rotate synchronously and make the paddle 335 fixed on its surface rotate accordingly. The paddle 335 on the rotating shaft reciprocates to paddle the paddle 335 at the end of the cross bar 334. Under the action of the coil spring 336, the cross bar 334 drives the rotating seat 332 to swing back and forth. The cold air discharged from the exhaust cooling pipe 318 blows on the discharged aluminum profile above through the nozzle 333.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
