[0002] Heat treatment of aluminum profiles is a technology that changes the microstructure of the material by controlling the heating and cooling process to improve or adjust its mechanical properties. Generally, high temperature is used to promote the refinement of the internal grains of the aluminum profile, thereby improving the strength, hardness and toughness of the aluminum profile, and then the high-temperature aluminum profile is quickly cooled and quenched to further improve the strength and hardness of the material.

[0003] At present, when water-cooling aluminum profiles are quenched, in order to avoid the internal stress and deformation of the aluminum profiles caused by too fast cooling speed, water-cooling quenching is usually carried out by spraying water.

The outer diameter of the aluminum profile is adapted to the inner diameter of the insertion groove 321, and the upper and lower pushing rollers 4 near the feed bin 3 are meshed and connected by a gear set 41. A first motor 42 is fixedly connected to the top of the heating box 1, and the output shaft of the first motor 42 is connected to the rotating shaft of the pushing roller 4 near the feed bin 3 through a pulley set 43, and a reducer is installed on the output shaft of the first motor 42. The setting of the reducer can reduce the forward speed of the aluminum profile, so that it can obtain sufficient heating time, thereby ensuring the heat treatment effect.

[0038] Through the arrangement of the above structure, the first motor 42 is turned on, and through the transmission action of the pulley set 43 and the gear set 41, the upper and lower push rollers 4 are driven to rotate in opposite directions, thereby pushing the aluminum profile to move toward the feed bin 3, thereby performing heating treatment while moving, effectively improving the processing efficiency.

[0040] It should be noted that the one-way valve in the air guide pipe 564 can only allow the gas in the piston box 56 to enter the water storage tank 53.

[0041] By setting the above structure, the water cooling plate 5 will rotate under the friction between the friction wheel 54 and the water cooling plate 5, and the water flow in the water storage tank 53 will also enter the water cooling plate 5 under the action of gravity, and spray along the water spray hole 52 to the middle part of the inner cavity of the water cooling chamber 33. At the same time, the piston plate 562 will also rotate synchronously with the friction wheel 54. Under the repulsive action of the magnetic plate 561 and the piston plate 562, the piston plate 562 will slide to the side of the compression return spring 563, thereby compressing the piston box 5 6, and open the one-way valve in the air guide pipe 564, so that the gas in the piston box 56 is filled into the water storage tank 53, thereby increasing the air pressure at the top of the water storage tank 53, so that the water cooling plate 5 is quickly filled after obtaining a certain impulse, thereby ensuring the liquid storage in the water cooling plate 5, so that sufficient water flow can be continuously sprayed from the water spray hole 52, thereby realizing comprehensive and uniform water-cooling quenching of the aluminum profile along with the rotation of the water cooling plate 5, effectively improving the quenching effect and ensuring the quality of the aluminum profile.

[0042] Reference Figure 3 , Figure 4 and Figure 6 The guide assembly includes a guide box 6, which is fixed in the heating box 1. The guide box 6 is divided into four groups, and the upper and lower groups of guide boxes 6 are symmetrically arranged along the center of the heating box 1. A guide blade 61 is rotatably connected in the guide box 6. Four groups of drive boxes 62 are fixedly connected to the outer wall of the heating box 1. The four groups of drive boxes 62 are respectively adapted to the four groups of guide boxes 6. The rotating shaft of the guide blade 61 passes through the drive box 62 and is fixedly connected with a pneumatic impeller 611. An upper steam pipe 621 is penetrated and connected between the upper two groups of drive boxes 62, and a lower steam pipe 622 is penetrated and connected between the lower two groups of drive boxes 62, and the input ends of the upper steam pipe 621 and the lower steam pipe 622 are both connected to the upper part of the inner cavity of the discharge bin 31.

[0043] Through the arrangement of the above-mentioned structure, a large amount of high-pressure steam will be generated when the quenching water flow encounters the high-temperature aluminum profile. At this time, the high-pressure steam will flow through each drive box 62 along the upper steam pipe 621 and the lower steam pipe 622, thereby driving the guide blades 61 in each group of guide boxes 6 to rotate, so that the upper and lower groups of guide boxes 6 both produce a diversion effect toward the aluminum profile, so that the heat from various places in the heating box 1 can be quickly moved to the aluminum profile, effectively improving the heat treatment efficiency.

[0044] Reference Figure 3 , Figure 4, wherein a cleaning bin 34 is fixed on the feed bin 3 and connected thereto, the output ends of the upper steam pipe 621 and the lower steam pipe 622 respectively extend through and extend to both sides of the inner cavity of the cleaning bin 34, a liquid collecting box 63 is fixedly connected to the bottom of the heating box 1, two groups of condensing pipes 631 are fixedly connected to one side of the liquid collecting box 63, the other end of the condensing pipes 631 are connected to the bottom of the inner cavity of the cleaning bin 34, two groups of liquid extraction pipes 632 are fixedly connected to the other side of the liquid collecting box 63, the other end of the liquid extraction pipes 632 are connected to the inner cavity of the piston box 56, and a one-way valve is arranged in the liquid extraction pipes 632.

[0045] It should be noted that the one-way valve in the liquid extraction tube 632 can only allow air flow from the liquid extraction tube 632 to enter the piston box 56.

[0046] Through the arrangement of the above structure, the steam will continue to enter the cleaning chamber 34 along the upper steam pipe 621 and the lower steam pipe 622, thereby spraying high-temperature steam to the side walls of the aluminum profile from both sides, so as to clean the surface of the aluminum profile, ensure the neatness of the surface of the aluminum profile, improve the visual quality of the surface of the aluminum profile after heat treatment, and preheat the aluminum profile at the same time, effectively reduce the temperature gradient of the aluminum profile entering the heating box 1 from the outside, avoid thermal stress and deformation caused by excessive temperature difference, and improve the heat treatment quality of the aluminum profile; at the same time, when the magnetic plate 561 and the piston plate 562 are separated from the repulsive area, under the rebound action of the reset spring 563, the piston plate 562 will reset and slide, thereby generating suction in the piston box 56, thereby opening the one-way valve in the liquid extraction pipe 632, so that the steam entering the cleaning chamber 34 enters the condensing pipe 631, and finally falls back into the liquid collecting tank 63 after being condensed and liquefied, thereby reducing water flow consumption and improving energy saving effects.

[0047] Reference Figure 4 , Figure 5 Among them, the bottoms of the two sets of limit rings 51 are fixedly connected with drain pipes 512, and the two ends of the drain pipes 512 are respectively connected with the inner ring cavity and the outer ring cavity of the water cooling warehouse 33. The bottom of the water cooling warehouse 33 is fixedly connected with a water storage pipe 35, and the top of the water storage pipe 35 is connected with the outer ring cavity of the water cooling warehouse 33. The output end of the water storage pipe 35 is fixed and connected with a drain pipe 351, and an electromagnetic valve is arranged in the drain pipe 351.

[0048] Through the arrangement of the above-mentioned structure, when the quenching water flow is sprayed in the water-cooling bin 33, a part of the water flow that has not been evaporated will fall to the bottom of the inner ring cavity of the water-cooling bin 33, and enter the outer ring cavity of the water-cooling bin 33 along the drain pipe 512. At this time, part of the water flow will adhere to the friction wheel 54, so as to dissipate heat and cool the friction wheel 54, effectively reducing the thermal wear of the friction wheel 54 and improving the durability of the friction wheel 54; the excess water flow will continue to fall into the water storage pipe 35, and finally the solenoid valve in the drain pipe 351 can be opened to discharge it.

[0049] Reference Figure 4 Among them, the bottom of the inner cavity of the water cooling bin 33 and the cleaning bin 34 are respectively lower than the feeding bin 3 and the discharging bin 31. The feeding bin 3, the discharging bin 31, the water cooling bin 33 and the cleaning bin 34 are all arranged in a circular shape and the center of the circle is on the same axis; this can ensure that the aluminum profile moves forward in a straight state, avoid deformation of the aluminum profile due to heat, and improve the heat treatment effect of the aluminum profile.

[0050] Embodiment 2:

[0051] Reference Figure 1-Figure 8 , which is basically the same as the first embodiment, a heat treatment method for aluminum profiles is proposed on the basis of the first embodiment, and the steps are as follows:

[0052] Step 1: insert the aluminum profile into the heating box 1 for heating;

[0053] Step 2: water-cooling and quenching the aluminum profile moved to the discharge bin 31 after heating;

[0054] Step 3: Using the steam generated by water cooling, the hot air flow in the heating box 1 is pushed to move toward the aluminum profile;

[0055] Step 4: Condensate and recover the steam generated by water cooling.

[0056] Reference Figure 1-Figure 8 In the present invention, when in use, the aluminum profile is inserted into the heating box 1 along the insertion groove 321 at the feed bin 3, and passed between the three groups of push rollers 4 until it passes through the insertion groove 321 at the discharge bin 31. At this time, the heater 2 is turned on to heat the inside of the heating box 1, so as to promote the refinement of the internal grains of the aluminum profile, thereby improving the strength, hardness and toughness of the aluminum profile, and at the same time, it can eliminate the internal stress of the aluminum profile and reduce the risk of deformation and cracking of the aluminum profile during subsequent processing or use; and at this time, each group of insertion grooves 321 will be fitted and blocked by the aluminum profile, effectively reducing the heat loss and improving the energy saving effect, and then the first motor 42 is turned on to drive the upper and lower push rollers 4 to rotate in the opposite direction through the transmission action of the pulley group 43 and the gear group 41, so as to push the aluminum profile to move toward the feed bin 3, so as to move while heating, effectively improving the processing efficiency.

[0057] When the aluminum profile moves toward the feed bin 3, the second motor 55 is turned on at the same time to drive the friction wheel 54 to rotate, and the solenoid valve in the water conduit 531 is turned on. At this time, under the friction between the friction wheel 54 and the water cooling plate 5, the water cooling plate 5 will rotate, and the water flow in the water storage tank 53 will also enter the water cooling plate 5 under the action of gravity, and spray along the water spray hole 52 to the middle part of the inner cavity of the water cooling bin 33. At the same time, the piston plate 562 will also rotate synchronously with the friction wheel 54. Under the repulsive action of the magnetic plate 561 and the piston plate 562, the piston plate 562 will be compressed and restored. The one side of the position spring 563 slides to compress the gas in the piston box 56 and open the one-way valve in the air guide pipe 564, so that the gas in the piston box 56 is filled into the water storage tank 53, thereby increasing the air pressure at the top of the water storage tank 53, so that the water cooling plate 5 is quickly filled after obtaining a certain impulse, thereby ensuring the liquid storage condition in the water cooling plate 5, so that sufficient water flow can be continuously sprayed from the water spray hole 52, thereby realizing comprehensive and uniform water-cooling quenching of the aluminum profile along with the rotation of the water cooling plate 5, effectively improving the quenching effect and ensuring the quality of the aluminum profile.

[0058] At the same time, when the quenching water flow encounters the high-temperature aluminum profile, a large amount of high-pressure steam will be generated. At this time, the high-pressure steam will flow through each drive box 62 along the upper steam pipe 621 and the lower steam pipe 622, thereby driving the guide blades 61 in each group of guide boxes 6 to rotate, so that the upper and lower groups of guide boxes 6 both have a diversion effect toward the aluminum profile, so that the heat in various places in the heating box 1 is quickly moved to the aluminum profile, effectively improving the heat treatment efficiency; then the steam will continue to enter the cleaning chamber 34 along the upper steam pipe 621 and the lower steam pipe 622, so as to spray high-temperature steam from both sides to the side walls of the aluminum profile, so as to clean the surface of the aluminum profile. , and preheat the aluminum profile at the same time, effectively reducing the temperature gradient of the aluminum profile entering the heating box 1 from the outside, avoiding thermal stress and deformation caused by excessive temperature difference, and improving the heat treatment quality of the aluminum profile; at the same time, when the magnetic plate 561 and the piston plate 562 are separated from the repulsive area, under the rebound action of the reset spring 563, the piston plate 562 will reset and slide, thereby generating suction in the piston box 56, thereby opening the one-way valve in the liquid extraction pipe 632, so that the steam entering the cleaning chamber 34 enters the condensing pipe 631, and finally falls back into the liquid collecting tank 63 after being condensed and liquefied, thereby reducing water flow consumption and improving energy saving effects.
