Description

Technical Field

[0001] The invention relates to the technical field of aging furnaces for alloy materials, in particular to an aging furnace for aging heat treatment of alloy materials. Background Art

[0002] Aging in an aging furnace refers to a heat treatment process in which alloy workpieces undergo solution treatment, cold plastic deformation, casting, or forging, then are placed at elevated temperatures or at room temperature to maintain their properties, shape, and dimensions over time. The purpose of aging treatment is to eliminate internal stresses in the workpiece, stabilize its structure and dimensions, and improve its mechanical properties. For aging strengthening, when solution treatment is performed before aging, the heating temperature must be strictly controlled to maximize the solute atoms' incorporation into the solid solution without causing the alloy to melt. The allowable deviation in heating temperature for solution treatment of many aluminum alloys is only approximately 5°C. Artificial aging treatment requires strict control of heating temperature and holding time to achieve the desired strengthening effect.

[0003] In the existing aging heat treatment steps, the cut alloy materials are generally stacked in an aging cage, and multiple aging cages filled with alloy materials are pushed into the aging furnace by a conveyor device, and the aging door is closed. The aging furnace is operated to heat the alloy materials inside the aging furnace to a set temperature and keep the temperature. After the aging heat treatment is completed, the temperature inside the aging furnace is cooled, and the alloy materials in the aging cages are cooled at the same time. After cooling is completed, the aging door is opened and the aging cages are pulled out of the aging furnace.

[0004] In the process of cooling the inside of the aging furnace before opening the aging door, due to the close stacking of multiple aging cages (the purpose of stacking is to quickly heat the alloy material in the aging furnace located in the middle through heat conduction), the heat dissipation efficiency of the alloy material in the aging cage located inside is poorer than that of the alloy material in the aging furnace located outside. The internal heat cannot be dissipated for a long time, and the heat generated inside acts on the alloy material in the aging cage located outside through heat conduction, resulting in low overall cooling efficiency and uneven cooling.

[0005] To this end, we propose an aging furnace for aging heat treatment of alloy materials. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-Figure 3 The figure shows an aging furnace for aging heat treatment of alloy materials, comprising a furnace body 1, aging doors 2 movably fitted at both ends of the furnace body 1, a conveying block 3 with multiple aging cages slidably fitted inside the furnace body 1; a cooling assembly 4 for cooling the middle of the aging cage, which is arranged in the furnace body 1; a movable assembly 10 for intermittently moving the cooling assembly 4, which is arranged in the cooling assembly 4; and a moving assembly 22 for cooperating with the movable assembly 10 to move multiple aging cages back and forth, which is arranged on the conveying block 3.

[0033] See also Figure 4 and Figure 7-Figure 8The cooling assembly 4 shown in the figure includes a movable tube 5 with a symmetrical structure. A limit frame 6 is fixedly connected to the movable tube 5. A plurality of release holes 7 are distributed in gaps on the movable tube 5. A sliding block 8 connected to the release hole 7 is slidably fitted in the limit frame 6. A sleeve 9 is rotatably connected to the sliding block 8. The end of the sleeve 9 is rotatably connected to the cooling tube buried in the furnace body 1.

[0034] See also Figure 10-12 The movable component 10 shown in the figure includes a motor 11 embedded and fixed in the furnace body 1. The output shaft of the motor 11 is fixedly connected to an incomplete gear 12. The incomplete gear 12 is engaged with a first gear 13 that is connected and fixed to the sleeve 9. The end of the output shaft of the motor 11 is also provided with a stabilizing component 14 that allows the sleeve 9 to smoothly stop rotating in the gap.

[0035] See also Figure 11-12 The stabilizing component 14 shown in the figure includes a pressure plate 15 connected and fixed to the end of the output shaft of the motor 11, a groove 16 is provided on the pressure plate 15, and a pressure column 17 is pressed and fitted at the edge of the pressure plate 15. A ratchet 18 connected and fixed to the pressure column 17 is rotatably connected in the furnace body 1, and a first tooth plate 19 sliding in the furnace body 1 is snap-fitted on the ratchet 18. A fixed rod 20 is rotatably connected in the furnace body 1, and a tension spring 21 is hung and fitted between the fixed rod 20 and the ratchet 18.

[0036] The plurality of release holes 7 are movably matched with the moving sliding block 8 via the rotating incomplete gear 12 .

[0037] See also Figure 9 The sliding block 8 shown in the figure is provided with two obliquely distributed communicating holes 34 communicating with the sleeve 9 , and the communicating holes 34 are in communication with the release hole 7 .

[0038] In this embodiment, multiple aging cages are moved into the furnace body 1 by the conveying block 3, and the aging door 2 is closed. After the heating aging treatment, the cooling pipe of the furnace body 1 is opened to release the cold air after the aging treatment is completed. The output shaft of the motor 11 rotates, driving the incomplete gear 12, driving the first gear 13 to rotate, and the rotating first gear 13 drives the sleeve 9 to rotate, driving the sliding block 8 to move. Under the action of the limit frame 6, the movable tube 5 moves downward, and the sliding block 8 moves along the limit frame 6. The cold air of the cooling pipe passes through the sleeve 9 and the sliding block 8, and enters the movable tube 5 through the release hole 7, and is dispersed out through other release holes 7. While the incomplete gear 12 moves, the pressure plate 15 rotates, and the pressure column 17 is in the groove 16, and is in the tension spring. Under the action of 21, the ratchet 18 moves away from the first tooth plate 19, and the first gear 13 drives the first tooth plate 19 to move. When the teeth of the incomplete gear 12 do not act on the first gear 13, the non-groove 16 position of the pressure plate 15 contacts the pressure column 17, thereby rotating the ratchet 18, and the ratchet 18 engages the first tooth plate 19, so that the first gear 13 and the first tooth plate 19 are firmly held in position, thereby keeping the sleeve 9 in position, thereby completing the gap rotation and pause of the sleeve 9, and the movable tube 5 moves up and down and pauses in the gap, and the movable tube 5 moving downward drives the two bottom support plates 23 away from each other, thereby moving the movable tube 5 between the two bottom support plates 23, and cooling the inner sides of multiple aging cages, wherein the output shaft of the motor 11 rotates forward and reverse.

[0039] Example 2

[0040] This second embodiment is a further supplement and explanation of the first embodiment. Figure 4-Figure 6 The moving assembly 22 shown in the figure includes a bottom support plate 23 that slides with the top surface of the conveying block 3, and multiple aging cages are placed on the bottom support plate 23. Two second gears 24 with a symmetrical structure are rotatably connected in the conveying block 3. The outer side of the second gear 24 is engaged with a third gear 25 that rotates with the conveying block 3. The central axis of the third gear 25 is fixed with a telescopic rod 26 that is rotatably connected to the bottom support plate 23. The conveying block 3 is provided with a rotating groove 27 that rotatably cooperates with the telescopic rod 26. The conveying block 3 is also provided with a pressure assembly 28 that cooperates with the movable tube 5 to drive the bottom support plate 23 to move.

[0041] In this embodiment, the movable tube 5 moving downward drives the second gear 24 and the third gear 25 to rotate, thereby driving the telescopic rod 26 to rotate along the rotation groove 27, thereby driving the bottom support plates 23 to move away from each other, wherein the telescopic rod 26 contracts under the action of the weight of the alloy material in the aging cage, thereby causing the bottom support plate 23 to slide in close contact with the top surface of the conveying block 3.

[0042] Example 3

[0043] This third embodiment is a further supplement and explanation of the second embodiment. Figure 6The pressure assembly 28 shown in the figure includes a pressure rod 29 that penetrates the conveying block 3. The pressure rod 29 is located between the two bottom supporting plates 23. The second tooth plates 30 that are in meshing contact with the second gear 24 are fixedly connected on both sides of the pressure rod 29. The side of the pressure rod 29 is fixedly connected to a compression spring 31 that cooperates with the conveying block 3. The top of the pressure rod 29 is pressed and cooperated with a sleeve rod 32 that is connected and fixed to the movable tube 5. The outer surface of the sleeve rod 32 is sleeved with a sleeve 33 that is connected and fixed to the furnace body 1.

[0044] In this embodiment, the movable tube 5 moving downward drives the sleeve rod 32 to move downward, thereby pressing the pressing rod 29. The pressing rod 29 moves, driving the second gear plate 30 to move, driving the second gear 24 to rotate, thereby causing the bottom supporting plates 23 to move relative to each other.
