Description

Technical Field

[0001] This utility model relates to a device for uniform cooling and quenching of aluminum alloy cast rods. Background Technology

[0002] After production, aluminum alloy bars require quenching. Quenching (i.e., solution treatment) involves rapid cooling to dissolve the alloying elements into the aluminum matrix, forming a supersaturated solid solution. This non-equilibrium structure provides the basis for subsequent age hardening, giving the material higher strength potential.

[0003] Currently, aluminum alloy bars are quenched by placing them in a quenching tank or by spraying them with a spray system. However, when aluminum alloy bars are placed directly into the quenching tank, the water temperature rises as the quenching process progresses. Spraying systems typically use cooling water to spray from both sides, resulting in uneven spraying. It is evident that quenching tanks and spraying systems have shortcomings in quenching aluminum alloy bars, and the existing quenching process needs further improvement. Therefore, to address the deficiencies of existing technologies, a uniform cooling and quenching device for aluminum alloy cast bars has been developed. Utility Model Content

[0045] Furthermore, this utility model, such as Figure 1 , 6 As shown in Figure 7, two sets of lifting gear transmission components 17 are installed on the worktable. The two sets of lifting gear transmission components 17 are installed at intervals.

[0046] like Figure 1 As shown, the drive mechanism includes a drive motor 24, a reduction gearbox 23 and a drive shaft 22. The reduction gearbox 23 has one input end and two output ends. The drive motor 24 is connected to the input end of the reduction gearbox 23. The two output ends of the reduction gearbox 23 are equipped with drive shafts 22. Each drive shaft 22 is connected to a corresponding set of lifting gear transmission components 17.

[0047] One structure of the downward air jet component includes a first air chamber 3, a first air nozzle 26, a first blower 11, and a first flexible air duct 12.

[0048] The first air chamber 3 is installed on the bottom surface of the lower spray chamber 53, and multiple first air nozzles 26 are installed at intervals along its length.

[0049] The first blower 11 is connected to the first air chamber 3 via the first flexible air duct 12.

[0050] The number of first air nozzles installed can be 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20, etc.

[0051] In use, the first blower 11 supplies air to the first air chamber 3 through the first flexible air duct 12, and the gas in the first air chamber 3 is ejected outward through the multiple first air nozzles 26 on the first air chamber 3.

[0052] One structure of the upper spray unit includes a short connecting pipe 30, a second flexible air duct 31, a second air chamber 32, second air nozzles 37, and a second blower 29. The second air chamber 32 is installed on the top of the upper spray chamber 151. The short connecting pipe 30 is installed on the quenching upper shell and communicates with the second air chamber 32. Multiple second air nozzles 37 are installed along the length of the bottom of the second air chamber 32. The second blower 29 is installed on the workbench 16 and is connected to the short connecting pipe 30 through the second flexible air duct 31.

[0053] The number of second air nozzles 37 installed can be 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20, etc.

[0054] In use, the second blower 29 supplies air to the second air chamber 32 through the second flexible air duct 31, and the gas in the second air chamber 32 is ejected outward through the multiple second air nozzles 37 on the second air chamber 32.

[0055] The second flexible air duct can be extended and retracted. When the upper shell of the quenching chamber is raised or lowered, the second flexible air duct can be compressed or extended accordingly.

[0056] The first and second nozzles can be hollow isosceles trapezoids with openings at both the top and bottom.

[0057] In some alternative embodiments, a structure for the guide roller spraying component is provided. The guide roller spraying component 6 includes a side spraying component, a bottom spraying component, and guide rollers 64. The side spraying component is positioned above the bottom spraying component, and the bottom spraying component is mounted on top of the lower spraying component. A plurality of guide rollers 64 are installed in parallel along the length direction on the side spraying component.

[0058] The spray nozzle can spray both sides of the aluminum rod.

[0059] The bottom spray unit can spray the bottom of the aluminum rod.

[0060] like Figure 1-4 As shown, the number of guide rollers 64 installed parallel to each other along the length of the side spray component can be 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20. The two ends of the guide rollers are rotatably mounted on the side spray component, and the guide rollers can rotate around their own axes. Therefore, multiple guide rollers on the side spray component can assist the aluminum rod in moving within the lower spray chamber of the quenching lower shell.

[0061] One installation structure of the side spray component in the lower spray chamber 53 is that the side spray component is installed in the lower spray chamber 53 by means of multiple brackets 68.

[0062] The number of brackets 68 can be 2, 3, 4, 5, or 6. Multiple brackets support the side spray elements higher than the bottom spray elements, enabling spraying of the sides of the aluminum rod.

[0063] In some alternative embodiments, one structure of the side spray member is provided. The side spray member includes two first longitudinal water supply members 61, which are arranged in parallel with a gap between them and connected at both ends by a transverse water guide member 62; wherein, each first longitudinal water supply member 61 is provided with a plurality of first spray nozzles 63 at intervals along the length direction.

[0064] Two first longitudinal water supply components 61 are installed in parallel at intervals along the length of the lower spray chamber 53.

[0065] Understandably, the two first longitudinal water supply components are installed in the lower spray chamber 53 via multiple brackets 68.

[0066] The number of first spray nozzles installed on each first longitudinal water supply component can be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20, etc.

[0067] One installation method for the first spray nozzle is to install the first spray nozzle at an angle on the first longitudinal water supply component.

[0068] One water supply structure of the side spray unit is equipped with a first water supply pipe 27. The first water supply pipe is connected to one of the two first longitudinal water supply components 61.

[0069] The first water supply pipe 27 supplies cooling water to the first longitudinal water supply component, and the cooling water in the first longitudinal water supply component is sprayed outward through multiple first spray nozzles on it. The two first longitudinal water supply components 61 are connected by transverse water guides 62, and the two transverse water guides 62 form a closed-loop water circuit.

[0070] One structural shape of the first longitudinal water supply component 61 and the transverse water guiding component 62 is a square tube.

[0071] In some alternative embodiments, one structure for the bottom spray element is provided. For example... Figure 3 , 5 As shown, the bottom spray unit includes two second longitudinal water supply components 65, which are arranged in parallel with a gap between them, and are connected by multiple transverse water distribution components 69. Each second longitudinal water supply component 65 is provided with multiple fifth spray nozzles 610 at intervals along its length, and each transverse water distribution component 69 is provided with at least one third spray nozzle 67.

[0072] The second longitudinal water supply component is connected to the transverse water distribution component, and water from the second longitudinal water supply component flows into the transverse water distribution component. Each transverse water distribution component 69 can be equipped with one, two, or three third spray nozzles 67. The third spray nozzles 67 are vertically installed on the transverse water distribution component 69, and each transverse water distribution component has at least one third spray nozzle 67 located on the vertical longitudinal center plane of the lower spray chamber 53. This facilitates spraying the bottom surface of the aluminum rod.

[0073] The number of fifth spray nozzles 610 that can be installed on the second longitudinal water supply component 65 is 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20, etc. The fifth spray nozzles 610 are installed at an angle on the second longitudinal water supply component 65.

[0074] The third and fifth spray nozzles spray cooling water outwards to quench the aluminum rods that have entered the quenching shell.

[0075] One structural shape of the second longitudinal water supply component 65 and the transverse water distribution component 69 is a square tube.

[0076] A water supply structure for the second longitudinal water supply component: The second longitudinal water supply component 65 is connected to the second water supply pipe 28. The second water supply pipe 28 supplies water to the second longitudinal water supply component.

[0077] In some alternative embodiments, one structure for the intermediate spray element is provided. For example... Figure 2 As shown, the intermediate spray unit 10 includes an intermediate longitudinal water supply unit 101, which is installed on the top of the lower spray chamber 53 and has a plurality of fourth spray nozzles 102 installed at intervals along the length direction.

[0078] like Figure 1 , 2 As shown, the number of intermediate spray elements 10 can be two, with one intermediate spray element 10 installed on each of the corresponding sides of the top of the lower spray chamber 53. The multiple fourth spray nozzles on the two intermediate spray elements can spray the top sides of the aluminum alloy rod.

[0079] The number of fourth spray nozzles 102 installed can be 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20, etc.

[0080] One water supply method for the intermediate spray unit 10 is as follows: the intermediate spray unit 10 is connected to the guide roller spray unit 6. The guide roller spray unit 6 supplies water to the intermediate spray unit 10. The intermediate spray unit 10 and the guide roller spray unit 6 can be connected by a water guide pipe 13. The water in the guide roller spray unit 6 is guided to the intermediate spray unit 10 through the water guide pipe 13.

[0081] In some optional embodiments, to facilitate the quenching upper shell covering the quenching lower shell, a support platform 51 and a limiting plate 52 are added. An outwardly protruding support platform 51 is installed on both sides of the top of the lower spray chamber 53, and a limiting plate 52 is installed on the side of the support platform 51 away from the lower spray chamber 53.

[0082] When the quenched upper shell 15 is fastened onto the quenched lower shell 5, the quenched upper shell 15 overlaps the support 51, and the support 51 supports the quenched upper shell fastening onto the top of the quenched lower shell.

[0083] The limiting plate 52 can restrict the lateral movement of the quenched upper shell that overlaps the support platform.

[0084] In some alternative embodiments, one structure of the lifting gear transmission element is provided. For example... Figure 1 , 6As shown in Figure 7, the lifting gear transmission component includes two vertical plates 175, a sliding shaft 179, two sets of sprocket rotating components, and a transmission chain 176. The two vertical plates 175 are installed parallel to each other on the support frame 4, and the vertical plates 175 are provided with sliding grooves 1751; one end of the sliding shaft 179 passes through the sliding grooves 1751 on the two vertical plates 175; the two sets of sprocket rotating components are installed aligned and spaced apart on the worktable 16. The sprocket rotating component 172 includes a sprocket 1725, a rotating shaft 1724, and a bearing seat 1723. The rotating shaft 1724 is fitted with the sprocket 1725 through a key, and both ends are supported by the bearing seats 1723 to achieve rotation; the transmission chain 176 is meshed with the sprockets 1725 of the two sets of sprocket rotating components for transmission, one end passes through the worktable 16 and is connected to the quenching upper shell 15 for transmission, and the other end passes through the worktable 16 and extends downward to insert between the two vertical plates 175 and is connected to the sliding shaft 179.

[0085] The sliding shaft 179 slides up and down along the groove 1751 on the vertical plate. When the transmission chain 176 rises or falls, it drives the sliding shaft to move. Since the sliding shaft is restricted between the two vertical plates, the sliding shaft can prevent the transmission chain from wobbling when it moves.

[0086] It should be noted that the drive motor in the drive mechanism has a self-locking force. When the drive motor stops, its self-locking force comes into play, restricting the rotation of the drive shaft connected to it. When the transmission chain pulls the upper quenching shell suspended above the lower quenching shell, the transmission chain pulls the sprocket connected to the drive shaft, but the sprocket does not drive the drive shaft to rotate.

[0087] Understandably, two lifting gear transmission components can be installed, and both are connected to the quenching upper housing. The drive mechanism can drive both lifting gear transmission components simultaneously.

[0088] like Figure 6 As shown, the sprocket rotating component 172 also includes a base plate 1721, which is mounted on the worktable 16 to support the two bearing seats 1723. The base plate 1721 has a through-hole 1722. The through-hole 1722 provides a channel for the transmission chain to pass through the base plate 1721.

[0089] like Figure 7 As shown, the sprocket rotating component 172 is connected to the quenched upper housing 15 via a support base 171.

[0090] Work style:

[0091] When the drive shaft rotates clockwise, it drives the sprocket to rotate, and the chain causes the quenched upper shell to descend.

[0092] When the drive shaft rotates counterclockwise, it drives the sprocket to rotate, and the chain drives the quenched upper shell to rise.

[0093] During quenching, the upper quenching housing needs to be placed on top of the lower quenching housing. The drive motor 23 drives the drive shaft to rotate clockwise. As the drive shaft rotates clockwise, it drives the sprocket to rotate, and the chain drives the upper quenching housing to descend. The drive motor can be stopped when the upper quenching housing is stably placed on the top surface of the lower quenching housing.

[0094] When the upper quenching shell needs to be detached from the lower quenching shell, the drive motor 23 drives the drive shaft to rotate counterclockwise. The counterclockwise rotation of the drive shaft drives the sprocket, which in turn causes the chain to lift the upper quenching shell. Once the upper quenching shell has detached from the top surface of the lower quenching shell and risen to the required height, the drive motor can be stopped. The drive motor's self-locking force locks the drive shaft in place; therefore, when the upper quenching shell pulls the sprocket connected to the drive shaft via the transmission chain, the sprocket cannot drive the drive shaft to rotate.

[0095] In some optional embodiments, in order to enable the transmission chain and sprocket to mesh and drive, an anti-detachment component is added. At least one of the two sets of sprocket rotating components is equipped with an anti-detachment component. The anti-detachment component includes an anti-detachment roller 173 and a roller frame 174. The roller frame 174 is installed near the position where the transmission chain 176 passes through the worktable 16 and extends obliquely toward the sprocket 1725 on the sprocket transmission component. The two ends of the anti-detachment roller 173 are rotatably installed on the roller frame 174 and attached to the transmission chain 176.

[0096] In this embodiment, as follows: Figure 1 , 6 As shown in Figure 7, when the number of anti-detachment components is 1, the anti-detachment component is used to support the transmission chain 176 on the sprocket rotating component 172 that is far away from the quenched upper shell, so that the transmission chain and the sprocket maintain a good meshing transmission connection.

[0097] In some optional embodiments, to better limit the lifting and lowering height of the drive chain, a first limit sensor 177, a second limit sensor 178, and a controller 9 are added. For example... Figure 7 As shown, the first limit sensor 177 and the second limit sensor 178 are respectively installed at one end of the slide groove 1751. The first limit sensor 177, the second limit sensor 178, and the drive mechanism are all electrically connected to the controller 9.

[0098] like Figure 7 As shown, one installation position of the first limit sensor 177 and the second limit sensor 178 is shown. The first limit sensor 177 is installed at the bottom end of the slide groove 1751, and the second limit sensor 178 is installed at the top end of the slide groove 1751.

[0099] In operation, when the sliding shaft 179 moves upward along the sliding groove 1751 and touches the second limit sensor 178, the second limit sensor 178 immediately sends data information to the controller 9. Upon receiving this data information, the controller stops the drive motor of the drive mechanism, and the transmission chain stops moving. When the sliding shaft 179 moves downward along the sliding groove 1751 and touches the first limit sensor 177, the first limit sensor 177 immediately sends data information to the controller 9. Upon receiving this data information, the controller stops the drive motor of the drive mechanism, and the transmission chain stops moving.

[0100] In some optional embodiments, at least one limiting sliding member is added to limit the swaying of the upper shell during lifting and lowering. Each limiting sliding member includes a guide rod 18, a roller 19, a guide rail 20, and a support rod 21. The worktable 16 has a through slot 161, and two guide rods 18 are installed in parallel and spaced apart on the upper shell 15. The support rod 21 passes through the through slot 161 and is inserted between the two guide rods 18. A guide rail 20 is installed on both sides, and each guide rail 20 is connected to the corresponding guide rod 18 through the roller 19.

[0101] The number of limiting sliding components can be 1, 2, or 3, etc. In this embodiment, two limiting sliding components are installed.

[0102] The support rod and the guide rod are slidably connected by guide rails and rollers.

[0103] Roller 19 is in a rolling connection with guide rail 20.

[0104] In some optional embodiments, a dehumidification mechanism 25, a water receiving tank 1, a water pump 2, a water blocking tank 14, a limiting roller 7, a support shaft 71, and a base 8 are added. The dehumidification mechanism 25 is installed at both ends of the quenching upper shell 15, a water receiving tank 1 is installed at one end of the lower spray chamber 53, and a water blocking tank 14 is installed at the other end. The water pump 2 is connected to the water receiving tank 1. The guide roller spray component has a base 8 installed at both ends. Multiple adjustment holes 81 are spaced apart on the base 8. Two limiting rollers 7 are spaced apart on the base 8. Each limiting roller 7 is equipped with a support shaft 71, which is inserted into the adjustment hole 81.

[0105] The water-blocking tank can seal off the end of the lower spray chamber away from the water receiving tank, preventing water generated by the spray from flowing out from that end. The top of the water-blocking tank 14 has an inclined opening 141. The inclined opening 141 facilitates the movement of the quenched aluminum alloy rod from the lower spray chamber through the water-blocking tank to the outside.

[0106] Wastewater generated during the quenching of the lower shell flows into water receiving tank 1, which is then recycled. Water pump 2 can pump the wastewater out of the water receiving tank to prevent it from overflowing.

[0107] like Figure 1-4As shown, each base is equipped with two limiting rollers 7, which restrict the swing of the aluminum rod. The limiting rollers are connected to the adjustment holes on the base via a support shaft. The support shaft passes through the limiting rollers and is inserted into the adjustment holes, thus restricting the limiting rollers to the base.

[0108] The base can have 4, 6, 8, 10, 12, 14, or 16 adjustment holes, etc. The distance between the two limit rollers on the base can be adjusted according to the diameter of the aluminum rod.

[0109] like Figure 1 , 6 As shown, the dehumidification mechanism 25 is used to extract water vapor overflowing from the quenching space formed by the splicing of the upper quenching shell 15 and the lower quenching shell 5. The dehumidification mechanism 25 includes an exhaust fan 251, a motor frame 252, a dehumidification pipe 253, and a moisture-absorbing component 254. The motor frame 252 is installed on the upper quenching shell 15, the exhaust fan 251 is installed on the motor frame 252, and the moisture-absorbing component 254 is installed on the end face of the upper quenching shell, with one end extending to the bottom of the upper quenching shell and the other end connected to the exhaust fan 251 through the dehumidification pipe 253.

[0110] In use, the upper quenching shell 15 covers the lower quenching shell 5 to form a quenching space. The two ends of the quenching space are not closed. When the aluminum rod is quenched in the quenching space, the water vapor generated by the spray cooling overflows from both ends of the quenching space. When the exhaust fan 251 is started, it drives the dehumidification pipe 253 and the moisture absorption component 254 to generate negative pressure. The moisture absorption component 254 can then absorb the water vapor overflowing from the quenching space and discharge the water vapor outside the workshop to prevent the water vapor from spreading in the workshop.

[0111] One structure of the moisture-absorbing component can be a hollow isosceles trapezoid. The top and bottom of the isosceles trapezoid are both open. The opening at the top of the isosceles trapezoid is connected to the dehumidification pipe, and the opening at the bottom is used to absorb water vapor.

[0112] According to the above embodiments, the working principle of this utility model is as follows:

[0113] The drive mechanism drives the lifting gear transmission component 17 to work, and the lifting gear transmission component 17 drives the quenching upper shell 15 to descend to the quenching lower shell 5, until it closes on the quenching lower shell 5. The upper spray chamber 151 of the quenching upper shell 15 and the lower spray chamber 53 of the quenching lower shell 5 constitute the quenching spray chamber.

[0114] The aluminum rod to be quenched is inserted into the quenching spray chamber from the end equipped with the water receiving tank 1. During insertion, multiple guide rollers 64 on the guide roller spraying component 6 support the aluminum rod to slide within the quenching spray chamber. The third spray nozzle 67 sprays the bottom of the aluminum rod, the second spray nozzle 66 sprays the bottom sides of the aluminum rod, the first spray nozzle 63 sprays the bottom sides of the aluminum rod, the fourth spray nozzle 102 sprays the top sides of the aluminum rod, and the sixth spray nozzle 36 sprays the top of the aluminum rod. Multiple third spray nozzles 67, second spray nozzles 66, first spray nozzles 63, fourth spray nozzles 102, and sixth spray nozzles 36 are spaced apart along the length of the quenching spray chamber. Therefore, the multiple third spray nozzles 67, second spray nozzles 66, first spray nozzles 63, fourth spray nozzles 102, and sixth spray nozzles 36 form an enveloping spray on the aluminum rod, ensuring that the aluminum rod is sprayed evenly. The first air chamber 3 installed on the lower quenching shell 5 sprays upward air into the quenching spray chamber through multiple first air nozzles 26, while the second air chamber 32 installed on the upper quenching shell sprays downward air into the quenching spray chamber through multiple second air nozzles 37. The sprayed air can push the water vapor generated by the spraying towards both ends of the quenching spray chamber quickly, while carrying away heat. The water vapor at both ends is then promptly removed by the dehumidification mechanism 25, thus improving the quenching effect.

[0115] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
