The air pump 12 is powered on and turned on to generate airflow inside the air pump 12 and discharge it into the exhaust pipe 13. The airflow blows toward the surface of the extruded aluminum material through the end of the exhaust pipe 13. At the same time, the water pump 15 is connected to the water source, and the water is discharged into the drain pipe 16 through the water pump 15. The water is then discharged from the end of the drain pipe 16, and the cooled airflow is blown toward the extruded aluminum material through the exhaust pipe 13.

In addition, the spraying angle can be changed by rotating the spray head 21 to adapt to aluminum flat wires of different specifications and shapes, effectively increasing the contact area between the water mist and the surface of the aluminum flat wire, and effectively improving the cooling efficiency of the aluminum flat wire.

[0026] like Figure 1 and Figure 4As shown, a fixing rod 3 is fixedly connected to the top of the workbench 1; the fixing rod 3 is fixedly connected to the end away from the winding drum 17; a support frame 31 is fixedly connected to the top of the fixing rod 3; the support frame 31 is U-shaped; the middle part of the support frame 31 is rotatably connected to two rollers 32; when working, the aluminum material to be processed is placed between the two rollers 32, and the two rollers 32 position the aluminum material. When the aluminum material is pushed, the two rollers 32 rotate simultaneously with the movement of the aluminum material, and the two rollers 32 can effectively position the aluminum flat wire when it is extruded, and can provide stable support and positioning during the extrusion of the aluminum flat wire. When effective, the aluminum flat wire maintains its position and direction during the transmission process, effectively reduces the deviation and swing of the aluminum flat wire during the extrusion process, effectively makes the accuracy and consistency of the aluminum flat wire extrusion operation, and can effectively make the aluminum flat wire be evenly and stably stressed during the extrusion process.

The sponge block 54 fits the surface of the extrusion wheel 11, and the lubricating oil is applied to the surface of the extrusion wheel 11. By applying the lubricating oil to the surface of the extrusion wheel 11, the friction between the extrusion wheel 11 and the aluminum flat wire can be effectively reduced, and the heat increase caused by a large amount of friction between the aluminum material and the extrusion wheel 11 during the extrusion of the aluminum flat wire can be effectively reduced.

The extruded aluminum material shakes and collides with the end of the wind guide cover 6 during collection, and contacts with the extruded aluminum material through the elastic ring 61. The airflow can be effectively guided by the wind guide cover 6 to blow toward the surface of the aluminum flat wire more evenly and stably, effectively reducing the uniform cooling of the aluminum flat wire during the extrusion process, effectively reducing the problem of quality degradation of the aluminum flat wire caused by excessively high or low local temperatures, and effectively guiding more cooled airflow to the surface of the aluminum flat wire, effectively reducing the problem of energy waste caused by airflow dispersion, and the elastic ring 61 can effectively reduce the damage caused by the collision when the aluminum flat wire contacts the wind guide cover 6, effectively improving the cooling efficiency of the aluminum flat wire.

Due to the softness and elasticity of the rubber pad 7 material, a buffer can be formed between the roller 32 and the aluminum flat wire, reducing the direct contact and wear between the roller 32 and the aluminum flat wire, and can effectively provide better friction control, which can effectively make the positioning of the aluminum flat wire on the roller 32 more stable, and reduce the deviation or jitter of the aluminum flat wire during the pressurization process.

[0031] During operation, the heated aluminum material is placed between the two extrusion wheels 11, and the two extrusion wheels 11 are rotated by a driving device. Under the action of the pressure of the two extrusion wheels 11, the aluminum material flows out from the outlets of the two extrusion wheels 11 to form a flat wire shape. The extruded aluminum material is then collected by a winding drum 17, and the air pump 12 is powered on and turned on to generate an airflow inside the air pump 12 and discharge it into the exhaust pipe 13. The airflow blows toward the surface of the extruded aluminum material through the end of the exhaust pipe 13. At the same time, the water pump 15 is connected to a water source, and water is discharged into the drain pipe 16 through the water pump 15. The water flow is then discharged from the end of the drain pipe 16. After the water flow enters the drain pipe 16, the temperature of the wet air flow decreases, and the water flow enters the two connecting pipes 2. The spray head 21 is rotated to a specified position, and the water flow is discharged from the inside of the spray head 21 and sprayed on the surface of the aluminum material. The aluminum material to be processed is placed between the two rollers 32. The two rollers 32 position the aluminum material. When the aluminum material is pushed, the two rollers 32 rotate simultaneously as the aluminum material moves. When the aluminum material moves through the two rollers 32, when the aluminum material is wider, the two elastic plates 4 are elastically expanded by the pressure of the aluminum material, and the impurities on the surface of the aluminum material are removed by the brushes 41 on both sides, and the lubricating oil is placed inside the oil bag 5. When the extrusion wheel 11 rotates, the lever 55 contacts and squeezes the oil bag 5. When the oil bag 5 is squeezed, the lubricating oil enters the roller 32 through the hose 51. At this time, the lubricating oil inside the oil outlet pipe 52 is discharged through the oil outlet hole 53, so that the lubricating oil enters the sponge block 54, and the sponge block 54 is attached to the surface of the extrusion wheel 11, and the lubricating oil is applied to the surface of the extrusion wheel 11. When the airflow is discharged from the end of the exhaust pipe 13, the airflow is guided by the air guide cover 6 so that the airflow blows to the surface of the extruded aluminum material. The extruded aluminum material shakes when being collected and collides with the end of the air guide cover 6, and contacts with the extruded aluminum material through the elastic ring 61.
