Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy surface treatment technology, specifically to a device for removing anodized film from aluminum alloys. Background Technology

[0002] In the processing and reuse of aluminum alloys, it is often necessary to remove the anodic oxide film on their surface.

[0003] Currently, common methods for removing anodized film from aluminum alloys mainly include chemical etching and mechanical polishing. Chemical etching utilizes a corrosive solution to react chemically with the oxide film, causing the film to dissolve and detach. However, in some existing cleaning devices, the aluminum alloy workpiece remains relatively stationary in the cleaning solution during the cleaning process, resulting in insufficient contact between the cleaning solution and the oxide film. This leads to poor oxide film removal effect and low removal efficiency, making it difficult to meet actual production needs. Therefore, this utility model proposes an aluminum alloy anodized film removal device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy anodized film removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy anodized film removal device, comprising an ultrasonic cleaning tank, wherein an auxiliary cleaning component is provided above the ultrasonic cleaning tank;

[0006] The auxiliary cleaning assembly is mounted on the ultrasonic cleaning tank by a first bracket and a second bracket. The auxiliary cleaning assembly includes a T-shaped structural plate mounted on the first bracket, a rectangular plate below the T-shaped structural plate, and clamping plates opposite each other in a guide groove below the rectangular plate. The clamping plates are connected by bidirectional screws in the guide groove. The protruding part of the T-shaped structural plate has a toothed groove, which meshes with the transmission teeth mounted on the second bracket. The transmission teeth are mounted on the second brackets at both ends by a rotating shaft, and the rotating shaft is connected to the output end of a reciprocating motor on one of the second brackets.

[0007] Preferably, the bidirectional screw rotating handle protrudes from the outside of the rectangular plate. By rotating the rotating handle, the bidirectional screw can be driven to rotate, thereby adjusting the distance between the two clamping plates.

[0008] Preferably, the clamping end faces of the two clamping plates are provided with a rubber layer to increase friction and prevent damage to the surface of the aluminum alloy plate.

[0009] Preferably, the reciprocating motor is detachably mounted on one of the second brackets via a protective sleeve.

[0010] Preferably, the first bracket and the second bracket are fixedly installed on the side wall of the ultrasonic cleaning tank by means of positioning seats and bolts.

[0011] Preferably, a controller is also integrated on the side wall of the ultrasonic cleaning tank, and the controller is electrically connected to the built-in drive component and reciprocating motor of the ultrasonic cleaning tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By driving the rotating shaft with a reciprocating motor, the transmission gear meshes with the tooth groove on the T-shaped structure plate, realizing the up-and-down reciprocating motion of the T-shaped structure plate and the aluminum alloy plate between the clamping plates. Combined with the cavitation effect generated by the ultrasonic cleaning tank, the contact frequency and contact area between the cleaning liquid and the oxide film layer are greatly increased, effectively solving the problem of poor cleaning effect and low efficiency caused by insufficient contact of the oxide film layer, significantly improving the cleaning efficiency and quality of the oxide film layer, and meeting the actual production needs;

[0014] (2) A rubber layer is provided on the clamping end face of the two clamping plates to increase friction and prevent damage to the surface of the aluminum alloy plate. While firmly clamping the aluminum alloy plate and making it reciprocate in the cleaning fluid, the clamping plates avoid causing clamping marks and wear on the surface of the aluminum alloy plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an aluminum alloy anodized film removal device, including an ultrasonic cleaning tank 1, with an auxiliary cleaning component 5 above the ultrasonic cleaning tank 1; the auxiliary cleaning component 5 is mounted on the ultrasonic cleaning tank 1 by a first bracket 2 and a second bracket 3, the auxiliary cleaning component 5 includes a T-shaped structure plate 51 mounted on the first bracket 2, a rectangular plate 52 below the T-shaped structure plate 51, and clamping plates 53 opposite each other in the guide groove below the rectangular plate 52, the clamping plates 53 being connected by a bidirectional screw 54 in the guide groove, the protruding part of the T-shaped structure plate 51 having a toothed groove 511, the toothed groove 511 meshing with a transmission tooth 55 mounted on the second bracket 3, the transmission tooth 55 being mounted on the second brackets 3 at both ends by a rotating shaft 56, and the rotating shaft 56 being connected to the output end of a reciprocating motor 57 on one of the second brackets 3.

[0022] The reciprocating motor 57 drives the rotating shaft 56, which in turn drives the transmission gear 55 to mesh with the tooth groove 511 on the T-shaped structure plate 51. This enables the aluminum alloy plate between the T-shaped structure plate 51 and the clamping plate 53 to move up and down. Combined with the cavitation effect generated by the ultrasonic cleaning tank 1, this greatly increases the contact frequency and contact area between the cleaning liquid and the oxide film layer. It effectively solves the problem of poor cleaning effect and low efficiency caused by insufficient contact of the oxide film layer, and significantly improves the cleaning efficiency and quality of the oxide film layer, meeting the actual production needs.

[0023] Please see Figures 1 to 4 The rotating handle of the bidirectional screw 54 protrudes from the outside of the rectangular plate 52. By rotating the rotating handle, the bidirectional screw 54 can be driven to rotate, thereby adjusting the distance between the two clamping plates 53.

[0024] Please see Figures 1 to 4 The clamping end faces of the two clamping plates 53 are provided with rubber layers 531 to increase friction and prevent damage to the surface of the aluminum alloy plate.

[0025] Please see Figures 1 to 4 The reciprocating motor 57 is detachably connected to one of the second brackets 3 via a protective sleeve.

[0026] Please see Figures 1 to 4 The first bracket 2 and the second bracket 3 are fixedly installed on the side wall of the ultrasonic cleaning tank 1 with the help of the positioning seat 4 and bolts.

[0027] Please see Figures 1 to 4 The ultrasonic cleaning tank 1 also integrates a controller 11 on its side wall. The controller 11 is electrically connected to the built-in drive unit and reciprocating motor 57 of the ultrasonic cleaning tank 1 through PLC programming control technology.

[0028] In use, firstly, according to the size of the aluminum alloy plate to be treated, adjust the distance between the two clamping plates 53 by rotating the handle of the bidirectional screw 54. After adjusting the distance, place the aluminum alloy plate to be cleaned of the anodized film between the two clamping plates 53. Use the rubber layer 531 on the end face of the clamping plates 53 to firmly hold the aluminum alloy plate. Then, activate the built-in drive of the ultrasonic cleaning tank 1 through the controller 1 to start the ultrasonic cleaning tank 1 and generate ultrasonic vibration. At the same time, start the reciprocating motor 57. The output end of the reciprocating motor 57 drives the rotating shaft 56 to rotate, and the transmission gear 55 installed on the rotating shaft 56 rotates accordingly. The transmission gear 55 meshes with the tooth groove 511 on the T-shaped structure plate 51. The rotation of the transmission gear 55 will drive the T-shaped structure plate 51 to reciprocate, which in turn causes the rectangular plate 52, the clamping plate 53 installed below the T-shaped structure plate 51, and the aluminum alloy plate clamped between the clamping plates 53 to reciprocate above the ultrasonic cleaning tank 1. Under the combined action of the ultrasonic vibration generated by the ultrasonic cleaning tank 1 and the reciprocating motion of the aluminum alloy plate driven by the auxiliary cleaning component 5, the anodic oxide film layer on the surface of the aluminum alloy plate is impacted by the cavitation effect of the ultrasonic waves and the mechanical force, which accelerates the breaking and peeling of the film layer, thereby achieving the purpose of efficiently removing the anodic oxide film layer.

[0029] 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 can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
