Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy quenching technology, specifically to a rapid quenching device for aluminum alloy plates. Background Technology

[0002] With the rapid development of modern industry, aluminum alloy sheets, due to their excellent specific strength, good processing performance, and corrosion resistance, are widely used in high-end manufacturing fields such as aerospace, new energy vehicles, high-speed trains, and 3C electronics. For example, key components in the aerospace field, such as aircraft skin and the body frame of new energy vehicles, rely on high-performance aluminum alloy sheets for structural support and safety assurance. The quenching process, as a core step determining the final mechanical properties of aluminum alloy sheets, directly affects the service life and reliability of the products.

[0003] Traditional aluminum alloy sheet quenching equipment produces oxide scale and impurities that easily adhere to the sheet surface during quenching, affecting subsequent processing and performance. This often requires additional processing steps, resulting in low production efficiency and increased costs. Furthermore, the use of stacked quenching methods, with close contact between sheets, prevents the cooling medium from making uniform and sufficient contact with the sheet surface, leading to uneven quenching and low cooling efficiency. Therefore, a rapid quenching device for aluminum alloy sheets is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a rapid quenching device for aluminum alloy plates to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rapid quenching device for aluminum alloy plates, comprising a base and a support frame, wherein a cleaning mechanism is provided on the top of the base and a quenching mechanism is provided on the bottom of the support frame;

[0006] The cleaning mechanism includes a rotating motor, the output end of which is fixedly connected to a first threaded rod. A movable plate is threadedly connected to the end of the first threaded rod away from the rotating motor. A transmission column is fixedly connected to the bottom of the movable plate. A scraper is fixedly connected to the bottom of the transmission column. A baffle is slidably connected inside the base. A second threaded rod is rotatably connected to the left side of the baffle. A handle is fixedly connected to the end of the second threaded rod away from the baffle. A collection box is installed at the bottom of the base, and a filter screen is installed inside the collection box.

[0007] Preferably, the quenching mechanism includes a cylinder, the output end of which is fixedly connected to a quenching frame, the inner wall of which is fixedly connected to a separation plate, and the inner wall of which is provided with a fixing plate.

[0008] Preferably, there are two rotating motors, which are fixedly connected to the top of the base, and the two rotating motors are symmetrically distributed on the base.

[0009] Preferably, a bearing is provided at the end of the first threaded rod away from the rotating motor.

[0010] Preferably, the separation plates are provided in multiple form and are evenly distributed on the inner wall of the quenching rack.

[0011] Preferably, a fixing groove is provided at the junction of the baffle and the water collection cavity opening, and a threaded groove adapted to the second threaded rod is provided inside the base.

[0012] Preferably, the filter screen is a pull-out movable design and is installed inside the collection box via a sliding groove.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this utility model drives a first threaded rod to rotate via a symmetrically arranged rotating motor. Through threaded engagement with a moving plate, the rotating motor drives a transmission column and a scraper at the bottom to move linearly along the bottom wall of the quenching tank. The scraper scrapes the oxide scale and other residues deposited at the bottom of the tank toward the slag collection area. This area is equipped with a sliding baffle. By rotating a throttle to drive a second threaded rod, the opening and closing of the baffle can be precisely controlled. When the baffle is open, the accumulated residue flows into the collection box below under the action of gravity, achieving the benefit of centralized cleaning of the residue.

[0015] Secondly, the quenching rack of this utility model achieves lifting and lowering movement through cylinder drive. When the conveyor belt delivers the aluminum alloy sheet to be processed to the quenching station, the cylinder pushes the quenching rack down, so that the sheet accurately enters the layered space between each separation plate. The separation plates are evenly distributed in the quenching rack, forming multiple independent quenching stations. The fixing plate is set on the inner wall of the quenching rack, which can effectively position the sheet during the quenching process. This design ensures that each sheet remains in an independent state during the quenching process, achieving the benefit that the cooling medium can fully contact the sheet.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A rapid quenching device for aluminum alloy sheets includes a base 1 and a support frame 3, with a cleaning mechanism 2 provided on the top of the base 1.

[0026] The cleaning mechanism 2 includes a rotating motor 201, with a first threaded rod 202 fixedly connected to the output end of the rotating motor 201. A movable plate 203 is threadedly connected to the end of the first threaded rod 202 away from the rotating motor 201. A transmission column 204 is fixedly connected to the bottom of the movable plate 203. A scraper 205 is fixedly connected to the bottom of the transmission column 204. A baffle 206 is slidably connected inside the base 1. A second threaded rod 207 is rotatably connected to the left side of the baffle 206. A handle 208 is fixedly connected to the end of the second threaded rod 207 away from the baffle 206. A collection box 209 is installed at the bottom of the base 1. A filter screen 210 is installed inside the collection box 209.

[0027] There are two rotating motors 201, which are fixedly connected to the top of the base 1. The two rotating motors 201 are symmetrically distributed on the base 1.

[0028] A bearing is provided at the end of the first threaded rod 202 away from the rotating motor 201.

[0029] A fixing groove is provided at the joint between the baffle 206 and the water collection cavity opening, and a threaded groove adapted to the second threaded rod 207 is provided inside the base 1.

[0030] The filter 210 is a pull-out movable design and is installed inside the collection box 209 via a sliding groove.

[0031] Through the above technical solution, two symmetrically arranged rotating motors 201 synchronously drive the first threaded rod 202 to rotate. The internal connection circuit of the rotating motors 201 is existing technology. Through threaded transmission, the rotational motion of the rotating motors 201 is converted into the linear motion of the moving plate 203. The transmission column 204 and scraper 205 connected below the moving plate 203 then perform cleaning operations on the bottom of the pool. This design ensures that the scraper can fully cover the bottom area of ​​the pool, scraping the deposited oxide scale, impurities and other residues to the preset slag collection area without dead corners. The key control component in the slag collection area is the sliding baffle 206, which is manually and precisely opened and closed via the second threaded rod 207 and the handle 208. When the baffle 206 is open, the accumulated residue flows into the collection box 209 located below the base 1 under the action of the hydrodynamic force and gravity of the quenching medium itself. The pull-out filter screen 210 inside the collection box 209 effectively separates the solid residue from the liquid quenching medium. The filter screen 210 can be easily pulled out for cleaning, achieving the benefit of centralized cleaning of the residue.

[0032] Example 2

[0033] Please see Figure 1 , Figure 2 , Figure 5 Furthermore, based on Example 1, the following is obtained: a quenching mechanism 4 is provided at the bottom of the support frame 3;

[0034] The quenching mechanism 4 includes a cylinder 404, the output end of which is fixedly connected to a quenching frame 401, a separation plate 402 is fixedly connected to the inner wall of the quenching frame 401, and a fixing plate 403 is provided on the inner wall of the quenching frame 401.

[0035] Multiple separation plates 402 are provided and are evenly distributed on the inner wall of the quenching rack 401.

[0036] With the above technical solution, when the conveying system transports the heated aluminum alloy sheet to the quenching station, the cylinder 404 is activated. The internal connection circuit of the cylinder 404 is existing technology, which pushes the quenching rack 401 to descend smoothly, so that each sheet is guided into an independent layered space separated by multiple separation plates 402. The separation plates 402 are evenly distributed on the inner wall of the quenching rack 401. They work together with the fixing plates 403 set on the inner wall to reliably position and separate the sheet. Each sheet is in an independent state, and sufficient gaps are maintained between the sheets, creating an unobstructed flow channel for the quenching medium. This effectively avoids cooling dead zones caused by sheet contact and achieves the benefit of the cooling medium fully contacting the sheet.

[0037] In actual operation, when this device is in use, the operator first transports the heated aluminum alloy sheet to the predetermined position above the quenching station through the conveying system. Then, the cylinder 404 is started to drive the quenching rack 401 to descend smoothly, so that the sheet accurately enters the independent layered space formed by each separation plate 402. The quenching medium then comes into full contact with the sheet and carries out a rapid and uniform cooling process. After quenching is completed, the cleaning mechanism 2 is started. The symmetrically arranged rotating motor 201 drives the scraper 205 to move along the bottom of the pool, scraping the settled oxide scale and other impurities to the slag discharge port. After the operator rotates the handle 208 to open the baffle 206, the impurities flow into the collection box 209 with the medium and are effectively intercepted by the filter screen 210, achieving the benefit of centralized cleaning of the residue.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
