Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile production technology, and in particular to a quenching device for aluminum alloy extruded profiles. Background Technology

[0002] Quenching generally involves heating the workpiece to a preset temperature using heating equipment, and then quickly placing the heated workpiece into a cooling medium. This process is called quenching. After quenching, the internal physical properties of the metal are changed, greatly improving its wear resistance, torsion resistance, and bending fatigue resistance.

[0003] In the heat treatment process of aluminum alloy profiles, the aluminum alloy profiles are usually heated in a furnace and then quenched in a water tank. Often, the aluminum alloy profiles are too long, making it difficult to handle the workpiece and thus difficult to process. Another treatment method is to cool the profiles by spraying cold water. However, by setting fixed nozzles for spraying, it is impossible to ensure that all parts of the irregular profiles are fully cooled, which can easily cause uneven cooling. Utility Model Content

Detailed Implementation

[0024] Example 1

[0025] like Figures 1-5 As shown in the figure, the aluminum alloy extruded profile quenching device proposed in this embodiment includes a frame 2, an upper water tank 4, a rotating pipe 5, an annular nozzle 6, a first roller conveyor 101, a second roller conveyor 102, a transmission assembly, and multiple water supply mechanisms.

[0026] A cooling water tank 3 is provided on one side of the bottom of the frame 2. A cooler and a microcontroller are installed on the cooling water tank 3. A temperature sensor is installed inside the cooling water tank 3. The cooler is an industrial chiller or a compressor-type water cooler, but is not limited to the above types of coolers. The temperature sensor is used to detect the water temperature inside the cooling water tank 3. When the water temperature inside the cooling water tank 3 exceeds the set threshold, the signal is fed back to the microcontroller, which then controls the cooler to work, thereby achieving the cooling of the coolant inside the cooling water tank 3.

[0027] Both ends of the rotating tube 5 are provided with rings 51. A filter screen 13 is installed on the side of the rotating tube 5 adjacent to the cooling water tank 3. The rotating tube 5 is rotatably mounted on the frame 2. The frame 2 is equipped with a power mechanism for driving the rotating tube 5 to rotate. The power mechanism includes a geared motor, a first gear 14 and a first gear ring 15. The geared motor is mounted on the frame 2, the first gear 14 is mounted on the output shaft of the geared motor, and the first gear ring 15 is mounted on the outer periphery of the rotating tube 5 and meshes with the first gear 14.

[0028] The annular nozzle 6 is located inside the rotating tube 5. A mounting ring 8 is connected to one side of the frame 2. A rotating ring 7 is rotatably mounted on the mounting ring 8. A connecting bracket 9 is connected between the rotating ring 7 and the annular nozzle 6.

[0029] The transmission assembly is installed on the side of the frame 2 to convert the rotational motion of the rotating tube 5 into the reciprocating rotation of the rotating ring 7. The transmission assembly includes a rectangular frame 17, a movable shaft 18, a sliding frame 19, a rack 20, a second gear 21, and a second gear ring 22. The sliding frame 19 is slidably installed on the frame 2. The rectangular frame 17 and the rack 20 are both connected to the sliding frame 19. The turntable 16 is installed on the output shaft of the geared motor. The movable shaft 18 is installed on the edge of the turntable 16 and is movably disposed in the sliding hole of the rectangular frame 17. A mounting bracket is connected to the frame 2. The second gear 21 is rotatably installed on the mounting bracket and meshes with the rack 20. The second gear ring 22 is installed on the outer circumference of the rotating ring 7 and meshes with the second gear 21.

[0030] The upper water tank 4 is located directly above the cooling water tank 3. A flexible hose connects the upper water tank 4 to the annular nozzle 6. A drain pipe connects the top of the upper water tank 4 to the cooling water tank 3. When the water supply exceeds the drainage, water will overflow from the upper water tank 4 after a certain period of time. The excess water in the upper water tank 4 can be redirected back into the cooling water tank 3 by setting up the drain pipe.

[0031] Multiple water supply mechanisms are installed on the outer periphery of the rotating pipe 5. The water supply mechanism includes a water tank 10, a third gear 23, a mounting frame 25, and a rotating frame 26. The mounting frame 25 is connected to the outer wall of the rotating pipe 5. The rotating frame 26 is rotatably mounted on the mounting frame 25 and connected to the water tank 10. The third gear 23 is mounted on the rotating shaft of the rotating frame 26. An arc-shaped rack 24 is connected to the top of the frame 2.

[0032] The first roller conveyor 101 and the second roller conveyor 102 are located on both sides of the cooling water tank 3, respectively.

[0033] Specifically, the aluminum alloy profile is conveyed by the first roller conveyor 101 and the second roller conveyor 102. Simultaneously, a power mechanism drives the rotating tube 5 to rotate. Cold water inside the upper water tank 4 flows through a hose to the annular nozzle 6. The annular nozzle 6 has multiple spray holes arranged in a ring array. The cold water inside the annular nozzle 6 is sprayed through these holes to multiple locations on the profile surface. With the cooperation of the transmission components, the rotating ring 7 and the annular nozzle 6 are reciprocated, causing them to rotate repeatedly. This increases the spray range of the annular nozzle 6 and prevents cooling issues. Dead angle; during the rotation of the rotating pipe 5, multiple water supply mechanisms are driven to rotate around the midpoint. It should be added that a counterweight is installed at the bottom of the water bucket 10. This setting ensures that the water bucket 10 remains vertical when rotated to any angle, preventing a large amount of water from overflowing from the inside of the water bucket 10. When the third gear 23 contacts the arc-shaped rack 24, as the third gear 23 rolls on the arc-shaped rack 24, the third gear 23 rotates, thereby driving the water bucket 10 to rotate. At this time, the coolant inside the water bucket 10 is poured into the upper water storage tank 4, thus realizing a continuous and uninterrupted water supply to the annular nozzle 6.

[0034] Example 2

[0035] like Figure 2 As shown, this embodiment of the aluminum alloy extruded profile quenching device differs from Embodiment 1 in that multiple partition plates 12 are connected between the two circular rings 51, multiple filter screens 13 are provided, and the multiple filter screens 13 and multiple partition plates 12 are spaced apart from each other; an arc-shaped baffle 11 is provided on the upper inner side of the rotating tube 5, the arc-shaped baffle 11 is connected to the upper water storage tank 4, and a storage box 27 is detachably installed in the middle of the arc-shaped baffle 11, and the storage box 27 and the arc-shaped baffle 11 are detachably installed by screws; a soft brush is installed on the inner side of the storage box 27; and an annular nozzle is also provided. The sprayed water flows to the lower inner side of the rotating pipe 5 and is discharged back into the cooling water tank 3 through the filter screen 13 for further cooling, thus achieving recycling. The filtered residue is retained inside the rotating pipe 5. During the rotation of the rotating pipe 5, the residue is carried to the upper end. The arc-shaped baffle 11 prevents the residue from falling downwards. When the residue moves to the position above the storage box 27, it falls into the storage box 27 under the action of gravity. Thus, the function of automatically collecting residue is realized during the rotation of the rotating pipe 5, which has the characteristics of high automation.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
