Description

Technical Field

[0001] This utility model relates to the field of electrophoresis technology, and in particular to a defoaming-free electrophoresis hanger for an energy-absorbing box. Background Technology

[0002] In the automotive manufacturing and metal processing industries, electrophoretic coating is a widely used surface treatment technology that provides excellent corrosion protection for energy-absorbing boxes. As a key energy-absorbing component, the quality of the electrophoretic coating on the surface of the energy-absorbing box is crucial, directly affecting the safety and durability of the equipment.

[0003] Currently, when electrophoresis is performed on workpieces with closed or semi-closed cavity structures, such as energy-absorbing boxes, a large amount of air will be trapped inside the workpiece when the workpiece is fixed by a hanger and immersed in the electrophoresis tank liquid. The gas inside the cavity hinders the normal deposition of electrophoretic paint on the inner surface of the workpiece, resulting in an excessively thin inner cavity electrophoretic layer, missed coating, or even complete failure to paint, forming bubble defects. Substandard inner cavity coating will significantly reduce the corrosion resistance of the workpiece, posing a risk of early rust and a potential threat to the overall quality and safe life of the product. To eliminate these bubbles, an additional defoaming process is usually required on the production line. This not only greatly increases labor and time costs, leading to low production efficiency, but also results in coating quality that is often difficult to match that of a product that passes the test the first time, and poor process stability. Utility Model Content

[0004] In view of the above-mentioned problems that the existing technology cannot meet the requirements of high-quality and high-efficiency electrophoresis production of workpieces with cavities, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a defoaming-free electrophoresis fixture for energy-absorbing boxes, which aims to fundamentally solve the problem of gas retention inside the workpiece.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a defoaming-free electrophoresis hanger for an energy-absorbing box, comprising a frame body, wherein a plurality of hanger frames are rotatably installed in the inner cavity of the frame body, and the plurality of hanger frames are distributed longitudinally at equal intervals in the inner cavity of the frame body, and a drive frame is hinged between one end of the plurality of hanger frames. The rack includes two rotatably mounted rotating bars, and two mounting plates are welded between the opposite faces of the two rotating bars. A clamp for placing workpieces is welded to one side of each mounting plate.

[0007] As an improved technical solution, the clamp consists of two arc-shaped clamping blocks, with the top of the arc-shaped clamping blocks being pointed. A cavity is provided between the two arc-shaped clamping blocks, and the workpiece has round holes that engage with the two arc-shaped clamping blocks.

[0008] As an improved technical solution, a first rotating shaft is rotatably provided at the middle position of both rotating bars, and a second rotating shaft is rotatably provided on the opposite side of the two rotating bars and on the side away from the mounting plate.

[0009] As an improved technical solution, the frame body includes two crossbeam angle irons, and vertical beam angle irons are welded between the tops of the two crossbeam angle irons. Connecting angle irons are welded between the opposite surfaces of the two crossbeam angle irons and between the tops of the opposite surfaces of the two vertical beam angle irons.

[0010] As an improved technical solution, lifting ring frames are welded to both sides of the top of the upper connecting angle iron, and a connecting frame is welded to the top of the upper connecting angle iron between the two lifting ring frames.

[0011] As an improved technical solution, the drive frame includes two vertical plates, and a second rotating shaft is rotatably mounted on the vertical plates. A connecting rod is welded between the top ends of the opposite surfaces of the two vertical plates, and a trapezoidal frame is welded between the two vertical plates near the outer side of the connecting rod end.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: 1. This utility model hangs the round hole on the workpiece on the arc-shaped clamping block to realize the snap-fit ​​installation between the clamp and the workpiece. This snap-fit ​​installation not only realizes the quick assembly and disassembly of the workpiece, improving work efficiency, but also does not require modification of the existing workpiece, which can be quickly installed on the hanger. In addition, the arc-shaped design of the arc-shaped clamping block also plays a role in blocking the workpiece when it is tilted, preventing the workpiece from falling off the clamp when it is tilted, thus ensuring the stability of the workpiece electrophoresis.

[0013] 2. This utility model uses a drive frame to drive the hanger to rotate, causing the workpiece to tilt in the electrophoresis tank. This removes the gas trapped in the internal cavity of the workpiece, ensuring that the electrophoretic paint can fully wet all the inner surfaces of the workpiece. This results in a uniform electrophoretic coating on both the inner and outer surfaces of the workpiece, effectively improving the pass rate of electrophoretic products. At the same time, the entire venting process is automatically completed by the rotation of the hanger, requiring no manual intervention. This makes it easy to integrate into automated production lines. Furthermore, it eliminates the defoaming process, avoiding secondary damage or contamination that may result from manual defoaming, and ensuring the integrity and consistency of the electrophoretic coating.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0019] Reference Figures 1-3 This is the first embodiment of the present utility model, which provides a defoaming-free electrophoresis hanger for an energy-absorbing box. This defoaming-free electrophoresis hanger for an energy-absorbing box includes a frame body 1. Several hanger frames 2 are rotatably installed in the inner cavity of the frame body 1, and the several hanger frames 2 are distributed longitudinally at equal intervals in the inner cavity of the frame body 1. A drive frame 3 is hinged between one end of the multiple hanger frames 2. The fixture 2 includes two rotating bars 21 that are rotatably set. Two mounting plates 22 are welded between the opposite faces of the two rotating bars 21. A clamp 9 for placing workpieces is welded to one side of the mounting plate 22. Multiple clamps 9 are set on one fixture 2, and multiple fixtures 2 are set longitudinally at the same time. Multiple workpieces can be electrophoresed at the same time, which can effectively increase the workload of a single processing and improve the efficiency of electrophoresis.

[0020] The drive frame 3 drives the hanger frame 2 to rotate, causing the workpiece to tilt in the electrophoresis tank. This removes the gas trapped in the internal cavity of the workpiece, ensuring that the electrophoretic paint can fully wet all the inner surfaces of the workpiece. This results in a uniform electrophoretic coating on both the inner and outer surfaces of the workpiece, effectively improving the pass rate of the electrophoretic products. At the same time, the entire venting process is completed automatically by the rotation of the hanger, without manual intervention. This makes it easy to integrate into automated production lines. Furthermore, it eliminates the defoaming process, avoiding secondary damage or contamination that may be caused by manual defoaming, and ensuring the integrity and consistency of the electrophoretic coating.

[0021] The clamp 9 consists of two arc-shaped clamping blocks 91, with the top of each block being a pointed tip. The arc shape of the clamping blocks 91 also serves to block the workpiece when it is tilted, preventing it from falling off the clamp 9 and ensuring the stability of the workpiece electrophoresis. A cavity 92 is provided between the two arc-shaped clamping blocks 91. The workpiece has round holes that engage with the two arc-shaped clamping blocks 91. By hanging the round holes on the workpiece onto the arc-shaped clamping blocks 91, the clamp 9 and the workpiece are connected and installed. This type of clamping installation not only enables quick assembly and disassembly of the workpiece, improving work efficiency, but also allows for quick installation of the workpiece onto the clamp without requiring any modification to the existing workpiece.

[0022] A first rotating shaft 23 is rotatably provided at the middle position of each of the two rotating bars 21, and a second rotating shaft 24 is rotatably provided on the opposite side of the two rotating bars 21 away from the mounting plate 22. The rotating bars 21 rotate around the first rotating shaft 23 as the rotation point, so that the end of the rotating bar 21 closer to the mounting plate 22 faces upward and the end away from the mounting plate 22 faces downward. At this time, the workpiece mounted on the fixture 9 is in an inclined downward state, thereby venting the gas inside the workpiece and filling the working cavity of the workpiece with electrophoretic liquid, avoiding the generation of electrophoretic bubbles and improving the quality of electrophoresis.

[0023] The frame body 1 includes two crossbeam angle irons 4, and vertical beam angle irons 5 are welded between the tops of the two crossbeam angle irons 4. The first rotation shaft 23 is welded to the vertical beam angle irons 5. Connecting angle irons 6 are welded between the opposite faces of the two crossbeam angle irons 4 and between the tops of the opposite faces of the two vertical beam angle irons 5.

[0024] Lifting rings 7 are welded to both sides of the top of the upper connecting angle iron 6. The lifting rings 7 facilitate the connection and hoisting of the hanger, thereby making it easy to move the hanger full of workpieces. A connecting frame 8 is welded to the top of the upper connecting angle iron 6 and between the two lifting rings 7.

[0025] The drive frame 3 includes two vertical plates 31, and the second rotating shaft 24 is rotatably mounted on the vertical plates 31. A connecting rod 32 is welded between the top ends of the opposite sides of the two vertical plates 31, and a trapezoidal frame 33 is welded between the two vertical plates 31 on the outer side near the end of the connecting rod 32.

[0026] The working principle of this utility model is as follows: The two arc-shaped locking blocks 91 on the clamp 9 and the cavity 92 are set to fit the two round holes of the workpiece itself. The round holes on the workpiece are hung on the arc-shaped locking blocks 91 to realize the locking and installation between the clamp 9 and the workpiece. After the workpiece is installed on the hanger, the entire hanger is placed into the electrophoresis tank, and all workpieces are immersed in the electrophoresis solution. Then, by applying downward pressure to the trapezoidal frame 33 or the connecting rod 32, the two vertical plates 31 are moved downward simultaneously. Under the rotation of the second rotating shaft 24 and the first rotating shaft 23, when the vertical plates 31 move in the direction of rotation, the rotating bar 21 will rotate around the first rotating shaft 23 as the rotation point, so that the end of the rotating bar 21 near the hanger plate 22 faces upward and the end away from the hanger plate 22 faces downward. At this time, the workpieces mounted on the fixture 9 are in a tilted downward state, thereby venting the gas inside the workpiece and filling the workpiece cavity with the electrophoresis solution.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
