Description

Technical Field

[0001] This utility model relates to the technical field of electrophoretic coating equipment, and in particular to an electrophoretic coating equipment for the production of metal workpieces. Background Technology

[0002] Electrophoretic coating is one of the processing steps in the production of metal workpieces. It is mainly completed in electrophoretic coating equipment and can form an anti-corrosion layer on the surface of metal workpieces, thereby improving the quality of metal workpieces.

[0003] In existing electrophoretic coating equipment, air bubbles on the surface of the electrophoretic tank can affect the coating quality. Since metal workpieces are mainly immersed in the electrophoretic tank by suspension for electrophoretic coating, it is difficult to remove air bubbles from the surface of the electrophoretic tank. This makes it difficult to remove them by mechanical stirring, thus affecting the processing quality of the metal workpieces. Therefore, this paper proposes an electrophoretic coating equipment for metal workpieces with the function of removing air bubbles from the liquid surface. Utility Model Content

[0004] The purpose of this invention is to provide an electrophoretic coating equipment for metal workpiece production, so as to solve the problems mentioned in the background art.

[0006] A coating bucket, with a hanger for suspending metal workpieces above it;

[0007] A mixing assembly is located above the hanging fixture, and a gantry frame is fixedly connected to the mixing assembly and the hanging fixture.

[0008] A defoaming component is movably connected to the gantry and can move vertically along the gantry. The defoaming component floats on the liquid surface inside the coating bucket.

[0011] A lifting assembly is disposed at the top of the coating bucket and extends upward, and the lifting assembly is used to drive the lifting plate to move up and down in the vertical direction.

[0012] Preferably, the lifting assembly includes:

[0013] A top beam is located above the lifting plate, and a hydraulic lifting rod for driving the lifting plate to rise and fall is fixedly connected to the middle of the top beam;

[0016] Preferably, the defoaming component is a rectangular plate, with both sides of the rectangular plate extending to the outside of the hanger. The rectangular plate is slidably connected to the gantry frame, and T-shaped plates are movably connected to both sides of the rectangular plate.

Detailed Implementation

[0024] 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.

[0025] This utility model provides, for example Figures 1-3 The image shows an electrophoretic coating equipment for producing metal workpieces.

[0026] Example 1: As Figure 1 and Figure 2 As shown, the system includes a coating tank 100 and a defoaming component 200. A hanger 101 for suspending metal workpieces is located above the coating tank 100. In this embodiment, the hanger 101 is a known prior art technique, and most electrophoretic coating equipment currently uses hangers 101 for workpiece suspension, so it will not be described in detail here. A stirring assembly is located above the hanger 101. A gantry frame 108 is fixedly connected between the stirring assembly and the hanger 101. The defoaming component 200 is movably connected to the gantry frame 108 and can move vertically along the gantry frame 108. The defoaming component 200 floats on the liquid surface inside the coating tank 100. The gantry frame 108 has two vertical rods, which are slidably connected to the defoaming component 200 to achieve radial limiting of the defoaming component 200, allowing the defoaming component 200 to rise and fall vertically. This is further enhanced by the stirring assembly. The component drives the gantry 108 to rotate slowly, allowing the defoaming component 200 to float on the surface of the liquid in the coating bucket 100 and rotate, thereby removing air bubbles from the liquid surface. At the same time, it drives the metal workpiece suspended below the hanger 101 to rotate slowly, which not only achieves the function of automatically removing air bubbles, but also makes the paint more evenly applied to the surface of the metal workpiece, improving the coating quality. The defoaming component 200 is a straight strip 201, which is movably set above the hanger 101, and the middle part of the straight strip 201 is slidably inserted into the outer wall of the hanger 101. The two ends of the straight strip 201 extend to the inner wall of the coating bucket 100. The straight strip 201 can float on the surface of the liquid in the coating bucket 100. The one-piece molding structure of the straight strip 201 can match the diameter and length of the coating bucket 100.

[0027] The stirring assembly includes a lifting plate 102 and a lifting component. The lifting plate 102 is rotatably connected to the top of the gantry frame 108. An agitator motor 103 is fixedly connected to the middle of the top of the lifting plate 102. The output end of the agitator motor 103 passes through the lifting plate 102 and is fixed to the gantry frame 108. The lifting component is located at the top of the coating tank 100 and extends upward. The lifting component is used to drive the lifting plate 102 to rise and fall vertically. The lifting component can drive the hanger 101 and the defoaming component 200 to rise and fall, so that they can enter the working position inside the coating tank 100, ensuring that the metal workpiece is completely immersed in the liquid surface inside the coating tank 100, and at the same time facilitating the loading and unloading of metal workpieces outside the coating tank 100. The agitator motor 103 consists of a motor and a motor housing, which slowly drives the gantry frame 108 to rotate, providing a power source for the rotation of the defoaming component 200 and the hanger 101.

[0028] In a preferred embodiment, the lifting assembly includes a top beam 104 located above the lifting plate 102. A hydraulic lifting rod 105 for driving the lifting plate 102 to rise and fall is fixedly connected to the middle of the top beam 104. Two support columns 106 are symmetrically fixedly connected to the two ends of the top beam 104. The top of the outer wall of the coating bucket 100 is provided with a support protrusion 107 fixed to the support columns 106. By extending and retracting the hydraulic lifting rod 105, the lifting plate 102 is driven to move up and down along the outer wall of the support columns 106, thus ensuring the stability of the lifting drive for the hanger 101 and the defoaming component 200.

[0029] Example 2: Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the defoaming component 200 is a rectangular plate 202, with both sides of the rectangular plate 202 extending to the outside of the hanger 101. The rectangular plate 202 is slidably connected to the gantry frame 108, and T-shaped plates 204 are movably connected to both sides of the rectangular plate 202. A convex slot 203 is provided on both sides of the bottom end of the rectangular plate 202. The end of the T-shaped plate 204 is slidably connected to the inner cavity of the convex slot 203. A return spring 205 is fixedly connected between the end of the T-shaped plate 204 and the inner wall of the convex slot 203. A ball bearing 206 is rotatably connected to the end of the T-shaped plate 204 facing away from the rectangular plate 202. In this embodiment, the return spring 205 is a weak tension spring, which provides elastic tension to the T-shaped plate 204 when it extends from the side wall of the rectangular plate 202. This allows the T-shaped plate 204 to match the inner diameter of the coating bucket 100 by extension and retraction, thereby increasing the adaptability of the defoaming component 200. The ball bearing 206 reduces the frictional resistance between the ball bearing and the inner wall of the coating bucket 100, allowing the rectangular plate 202 to float on the liquid surface of the coating bucket 100. If the inner diameter of the coating bucket 100 changes too much and the rectangular plate 202 cannot float with the liquid surface when stationary, it needs to be replaced with the straight plate 201 in embodiment 1.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
