Description

Technical Field

[0001] This invention belongs to the field of quenching spraying technology, specifically relating to a safe spraying device for quenching aluminum profiles. Background Technology

[0002] Aluminum profiles are widely used in many fields. In the process of processing aluminum profiles, in order to improve their performance, they need to be subjected to high-temperature treatment, and then the high-temperature treated aluminum profiles need to be quenched and sprayed. Therefore, appropriate aluminum profile quenching spraying equipment is required.

[0003] Currently, most existing aluminum profile quenching spraying equipment adopts a design of "fixed spray pipes at the top," meaning several pipes with spray heads are fixed parallel to each other at the top of the aluminum profile. A water pump delivers the cooling medium to the spray pipes, which is then sprayed downwards through the spray heads to cool the aluminum profile below. While this design achieves basic spraying cooling, it only sprays from a fixed position above the aluminum profile, limiting the spraying range. When spraying I-shaped aluminum profiles during quenching, the groove area formed at the junction of the web and flange, as well as the corners of the flange, remain in spray dead zones, failing to effectively cover the cooling medium. Therefore, overcoming these technical problems and defects is a key issue that needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, which can only spray from a fixed position above the aluminum profile, resulting in a limited spraying range. When spraying aluminum profiles with an "I"-shaped cross-section during quenching, the groove area formed at the connection between the web and the flange of the aluminum profile, as well as the corners of the flange, are always in the spray dead zone, and the cooling medium cannot be effectively covered. Therefore, this invention provides a safe spraying device for quenching aluminum profiles.

The lower end of the mobile pipe rack is connected to several spray pipes, and each spray pipe is connected to several spraying components that can spray aluminum profiles. A water storage tank is fixedly installed at the upper end of the spray box. Telescopic hoses are connected to the lower ends of both sides of the water storage tank. The end of each telescopic hose away from the water storage tank passes through the spray box and connects to the mobile pipe rack. A water pump is installed on the telescopic hose.

[0010] In the above-mentioned safe aluminum profile quenching spray equipment, a third shaped tube is rotatably installed at the end of the second shaped tube away from the first shaped tube. A third large gear is fixedly installed on the third shaped tube, and a third motor is fixedly installed on the second shaped tube.

[0011] In the aforementioned safe aluminum profile quenching spray equipment, the conveyor motor is a LEXY floor scrubber motor, and the first motor, second motor, and third motor are all JWP5065 waterproof motors.

[0012] In the aforementioned safe aluminum profile quenching spray equipment, the reciprocating mechanism includes a reciprocating motor, a drive shaft, a half gear, a reciprocating frame, a straight gear plate, a slot, and a drive rod.

[0020] This embodiment discloses a safe spraying device for quenching aluminum profiles. Through the ingenious design of the channel steel 9, traveling wheels 10, movable pipe frame 11, spray pipe 5, spraying components 6, water storage tank 2, telescopic hose 3, water pump 4, and reciprocating mechanism 8, the spray pipe 5 and spraying components 6 can reciprocate, thereby enabling reciprocating spraying of the aluminum profiles, effectively expanding the spraying range and reducing cooling dead zones. (Refer to...) Figures 1-7 It mainly includes a spray box 1, a liquid outlet 101, a material inlet 102, and a material outlet 103. The lower end of the spray box 1 is equipped with the liquid outlet 101, and the front and rear ends of the spray box 1 are respectively provided with the material inlet 102 and the material outlet 103. The spray box 1 is characterized by having a conveying mechanism 7 for conveying aluminum profiles fixedly installed inside. Channel steels 9 are symmetrically fixedly connected to both sides of the interior of the spray box 1. A movable pipe frame 11 is slidably connected between two channel steels 9 via wheels 10. The lower end of the movable pipe frame 11 is connected to several spray pipes 5, each... The spray pipe 5 is connected to several spraying parts 6 that can spray aluminum profiles. A water storage tank 2 (containing a cooling medium, such as cooling water) is fixedly installed at the upper end of the spray box 1. Telescopic hoses 3 are connected to the lower ends of both sides of the water storage tank 2. The end of each telescopic hose 3 away from the water storage tank 2 passes through the spray box 1 and connects to the movable pipe frame 11. A water pump 4 is installed on the telescopic hose 3. An installation shell 12 is fixedly installed at the upper end of the interior of the spray box 1. A reciprocating mechanism 8 that can drive the movable pipe frame 11 to move back and forth is installed on the installation shell 12. With the setting of the conveying mechanism 7, aluminum profiles can be conveyed and positioned over long distances. Operators do not need to come into close contact with the high-temperature aluminum profiles. They only need to assist in feeding and unloading at the inlet 102 and outlet 103. This effectively avoids safety accidents such as burns caused by direct contact or pushing of aluminum profiles by personnel, and significantly reduces safety hazards.

[0021] In this embodiment, refer to Figure 1 and Figure 3The conveying mechanism 7 includes a conveying frame 701, conveying rollers 702, sprockets 703, chains 704, and a conveying motor 705. The conveying frame 701 is fixedly installed inside the spray box 1. Several conveying rollers 702 are rotatably mounted on the conveying frame 701 at even intervals. Two sprockets 703 are fixedly installed at one end of each conveying roller 702. The sprockets 703 on adjacent conveying rollers 702 are connected by chains 704. The conveying motor 705 is fixedly installed on the conveying frame 701. The output shaft of the conveying motor 705 is fixedly connected to one of the conveying rollers 702. In practical use, the conveyor motor 705 is started, which drives the conveyor roller 702 to rotate. The conveyor roller 702 drives the sprocket 703 on it to rotate. Through the cooperation of the chain 704, the sprocket 703 on the adjacent conveyor roller 702 can rotate, which in turn makes the adjacent conveyor roller 702 rotate, so that the aluminum profile can be conveyed and moved as needed.

[0022] In this embodiment, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 Each of the spray pipes 5 is rectangular in shape and is sleeved on the conveying mechanism 7, enabling the spraying of cooling medium from the top, bottom, left and right directions of the aluminum profile, completely breaking the limitations of traditional single-sided or double-sided spraying, thus achieving a better spraying effect.

[0023] In this embodiment, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The spraying component 6 includes a connecting pipe 601, a first shaped pipe 602, a first large gear 603, a first motor 604, and a first small gear 605. The connecting pipe 601 is fixedly connected to the spraying pipe 5. The first shaped pipe 602 is rotatably mounted on the connecting pipe 601. The first large gear 603 is fixedly mounted on the first shaped pipe 602. The first motor 604 is fixedly mounted on the connecting pipe 601. The output shaft of the first motor 604 is fixedly mounted with a first small gear 605 that meshes with the first large gear 603. In practical use, the first motor 604 is started, which drives the first pinion 605 to rotate. The first pinion 605 meshes with the first large gear 603, causing the first large gear 603 to rotate. The first large gear 603 drives the first irregularly shaped tube 602 to rotate. Since the first irregularly shaped tube 602 is irregularly shaped, the cooling medium can flow out from different angles or directions, thereby spraying different parts of the aluminum profile such as the surface, edges, and grooves. This effectively avoids cooling dead zones, significantly improves the mechanical properties of the quenched aluminum profile, reduces deformation, and increases the product qualification rate.

[0024] In this embodiment, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A second shaped tube is rotatably mounted on the end of the first shaped tube 602 away from the connecting tube 601. A second large gear 607 is fixedly mounted on the second shaped tube, and a second motor 608 is fixedly mounted on the first shaped tube 602. A second small gear 609 that meshes with the second large gear 607 is fixedly mounted on the output shaft of the second motor 608. In actual use, the second motor 608 is started, which drives the second small gear 609 to rotate. The second small gear 609 meshes with the second large gear 607, causing the second large gear 607 to rotate, which in turn causes the second shaped tube to rotate. This allows the cooling medium to flow out from different angles or directions, further effectively avoiding cooling the four corners.

[0025] In this embodiment, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A third shaped tube 610 is rotatably mounted on the end of the second shaped tube 606 away from the first shaped tube 602. A third large gear 611 is fixedly mounted on the third shaped tube 610. A third motor 613 is fixedly mounted on the second shaped tube 606. A third small gear 612 that meshes with the third large gear 611 is fixedly mounted on the output shaft of the third motor 613. In practical use, the third motor 613 is started, which drives the third pinion 612 to rotate. The third pinion 612 meshes with the third large gear 611, causing the third large gear 611 to rotate. The third large gear 611 drives the third shaped tube 610 to rotate. The angle or direction of the cooling medium spray can be further adjusted according to the needs, which can further effectively avoid cooling dead zones, significantly improve the mechanical properties of the quenched aluminum profile, reduce deformation, and improve the product qualification rate.

[0026] In this embodiment, the conveyor motor 705 is a LEXY floor scrubber motor, and the first motor 604, the second motor 608, and the third motor 613 are all JWP5065 waterproof motors; this effectively prevents the influence of the cooling medium on the conveyor motor 705, the first motor 604, the second motor 608, and the third motor 613, thereby effectively ensuring the normal operation of the conveyor motor 705, the first motor 604, the second motor 608, and the third motor 613.

[0027] In this embodiment, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The reciprocating mechanism 8 includes a reciprocating motor 801, a drive shaft 802, a half gear 803, a reciprocating frame 804, a straight gear plate 805, a slot 806, and a drive rod 807. The reciprocating frame 804 is slidably connected inside the mounting shell 12. Straight gear plates 805 are symmetrically fixedly installed on both sides inside the reciprocating frame 804. The drive rod 807 is fixedly connected to the lower end of the reciprocating frame 804 for driving the moving pipe rack 11. The reciprocating motor 801 is fixedly installed at the upper end of the spray box 1. The output shaft of the reciprocating motor 801 passes through the spray box 1 and is fixedly connected to the drive shaft 802. A half gear 803 that meshes with a straight gear plate 805 is fixedly installed on the drive shaft 802. A slot 806 is provided in the middle of the reciprocating frame 804 for the reciprocating frame 804 to move left and right. In actual use, the reciprocating motor 801 is started, and the reciprocating motor 801 drives the half gear 803 to rotate. During one rotation of the plate gear, the half gear 803 meshes with the straight gear plate 805 in the reciprocating frame 804, causing the reciprocating frame 804 to move back and forth. The reciprocating frame 804 drives the drive rod 807 to move back and forth, and the reciprocating rod drives the moving tube frame 11 to move back and forth, thereby realizing the reciprocating spraying of aluminum profiles.

[0028] In this embodiment, refer to Figure 4 , Figure 5 and Figure 6 Two connecting plates 1101 are fixedly connected to the movable tube frame 11, and the drive rod 807 is located between the two connecting plates 1101 and extends to the lower end of the two connecting plates 1101. With the setting of the two connecting plates 1101, when the drive rod 807 moves left and right, the two connecting plates 1101 can be moved back and forth, thereby causing the movable tube frame 11 to move back and forth.

[0029] The working principle of the safe aluminum profile quenching spraying equipment of the present invention is as follows: When aluminum profiles need to be sprayed, the aluminum profiles are placed on the conveying rollers 702 through the inlet 102. The conveying motor 705 is started, and the conveying motor 705 drives the conveying rollers 702 to rotate. The conveying rollers 702 drive the sprockets 703 to rotate. The sprockets 703 mesh with the chain 704, causing the adjacent sprockets 703 to rotate, thereby causing each conveying roller 702 to rotate, thus conveying and moving the aluminum profiles. When the conveying is moved to a suitable position, the conveying motor 705 is turned off, and the water pump 4 is started. The cooling medium in the water storage tank 2 is pumped into the moving pipe frame 11 through the telescopic hose 3, and then the cooling medium flows into the spraying element 6 through the moving pipe frame 11. Finally, the cooling medium flows out from the spraying element 6 to spray the aluminum profiles. After the spraying is completed, the conveying motor 705 is started, and the above steps are repeated to allow the sprayed aluminum profiles to flow out from the outlet 103. At this time, the spraying process is completed.
