Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an electrophoresis device for sheet metal surface treatment. Background Technology

[0002] This device is suitable for surface electrophoretic treatment processes in small and medium-sized sheet metal processing plants, used for the preparation of anti-corrosion coatings on sheet metal parts. Traditional sheet metal electrophoretic treatment requires manual handling of the sheet metal, sequentially transferring it to the pretreatment tank, electrophoresis tank, and cleaning tank, resulting in high labor intensity and low efficiency. Furthermore, sheet metal is often secured using rope bindings or simple clamps, which can easily lead to tilting and swaying, resulting in uneven electrophoretic coating thickness. Additionally, the clamps have poor adaptability, making it difficult to secure sheet metal of different sizes, thus affecting the processing quality. Therefore, an electrophoresis device that can automatically transfer, stably clamp, and adapt to various sheet metal sizes is needed. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an electrophoresis device for sheet metal surface treatment, comprising a fixed base plate, a movable adjustment assembly provided on the fixed base plate, the movable adjustment assembly including a fixed frame, a drive motor connected to one end of the fixed frame, a one-way threaded rod connected to the output end of the drive motor, a threaded sleeve plate connected to the outer side of the one-way threaded rod, telescopic plates connected to both sides of the threaded sleeve plate, a rolling shaft connected to one end of the telescopic plate, a guide groove connected to the lower side of the fixed frame, and an electrophoresis treatment tank provided on the fixed base plate.

[0005] As a further description of the above technical solution:

[0006] A fixing component is provided on one side of the movable adjustment component. The fixing component includes a connecting plate one, a connecting plate two connected to one side of the connecting plate one, a bidirectional threaded rod connected to the inner side of the connecting plate two, a clamping plate connected to the outer side of the bidirectional threaded rod, and a sheet metal body provided on one side of the clamping plate.

[0007] As a further description of the above technical solution:

[0008] The one-way threaded rod is rotatably connected to the inner side of the fixed frame, the threaded sleeve is threadedly connected to the outer side of the one-way threaded rod, and the threaded sleeve is slidably connected to the inner slide rod of the fixed frame.

[0009] As a further description of the above technical solution:

[0010] The telescopic plate is provided in two sets and symmetrically arranged on both sides of the threaded sleeve plate. The rolling shaft is rotatably connected to one end of the telescopic plate, and the middle position of the rolling shaft is slidably rotatably connected to the inner side of the guide groove.

[0011] As a further description of the above technical solution:

[0012] The upper side of the first connecting plate is rotatably connected to the rolling shaft, and the second connecting plate has two sets and is symmetrically arranged on both sides of the first connecting plate.

[0013] As a further description of the above technical solution:

[0014] The bidirectional threaded rod is rotatably connected to the inner side of the second connecting plate, one side of the clamping plate is fitted to one side of the sheet metal body, and the clamping plate is slidably connected to the slide rod provided on the inner side of the second connecting plate.

[0016] The clamping plates are provided in two sets and symmetrically arranged on both sides of the sheet metal body, and the fixing components are located on the lower side of the guide groove.

[0017] This utility model has the following beneficial effects:

[0018] 1. Automatic transfer and lifting of fixed components are achieved through the moving adjustment component: The drive motor drives the one-way threaded rod to move the threaded sleeve plate, and the rolling shaft moves along the three-section guide groove. With the extension and retraction of the telescopic plate, the sheet metal is sequentially immersed into the pretreatment tank, electrophoresis tank and cleaning tank. No manual handling is required, which solves the problems of low efficiency and high labor intensity of manual transfer in traditional electrophoresis and improves the processing efficiency.

[0019] 2. The sheet metal is clamped by opposing clamping plates driven by a bidirectional threaded rod. Rubber pads enhance clamping stability, and L-shaped connecting plates ensure that the sheet metal is vertically immersed in the tank. At the same time, the clamping plate spacing is adjustable, which solves the problems of poor adaptability of traditional fixing devices and uneven electrophoresis caused by easy tilting of sheet metal, thus ensuring the electrophoresis quality of sheet metal surface.

[0029] Example 1:

[0030] like Figures 1 to 4As shown in the figure, the electrophoresis device for sheet metal surface treatment provided in this embodiment includes a fixed base plate 1, a movable adjustment component 2 is provided on the fixed base plate 1, the movable adjustment component 2 includes a fixed frame 21, one end of the fixed frame 21 is connected to a drive motor 22, the output end of the drive motor 22 is connected to a one-way threaded rod 23, the outer side of the one-way threaded rod 23 is connected to a threaded sleeve plate 24, both sides of the threaded sleeve plate 24 are connected to telescopic plates 25, one end of the telescopic plate 25 is connected to a rolling shaft 26, the lower side of the fixed frame 21 is connected to a guide groove 27, and an electrophoresis treatment tank 4 is provided on the fixed base plate 1.

[0031] In this embodiment, the fixed base plate 1, the movable adjustment component 2, the fixed component 3, and the electrophoresis treatment tank 4 constitute an electrophoresis device for sheet metal surface treatment according to this application.

[0032] Specifically, a fixing component 3 is provided on one side of the movable adjustment component 2. The fixing component 3 includes a connecting plate 31, a connecting plate 32 is connected to one side of the connecting plate 31, a bidirectional threaded rod 33 is connected to the inner side of the connecting plate 32, a clamping plate 34 is connected to the outer side of the bidirectional threaded rod 33, and a sheet metal body 35 is provided on one side of the clamping plate 34.

[0033] In this embodiment, the fixed base plate 1 is a rectangular steel plate made of Q235 steel, with a rust-proof paint coating on the surface; the fixing frame 21 of the movable adjustment component 2 is a "gate" shaped steel structure, fixed to one side of the fixed base plate 1 along its length; the electrophoresis treatment tanks 4 are arranged along the length of the fixed base plate 1, including one pretreatment tank, one electrophoresis tank, and one cleaning tank, all made of PP plastic. The fixed base plate provides stable support, the multi-tank layout adapts to the entire electrophoresis process, and the PP material is resistant to electrolyte corrosion.

[0034] Specifically, the one-way threaded rod 23 is rotatably connected to the inner side of the fixed frame 21, the threaded sleeve 24 is threadedly connected to the outer side of the one-way threaded rod 23, and the threaded sleeve 24 is slidably connected to the inner slide rod of the fixed frame 21.

[0035] In a preferred embodiment, the one-way threaded rod 23 has a trapezoidal thread, is made of 45# steel, and is chrome-plated. The inner side of the fixing bracket 21 has two sliding rods, parallel to each other on both sides of the one-way threaded rod, and slidably connected to the threaded sleeve plate 24. The chrome-plated surface reduces friction, and the double sliding rods restrict the rotation of the threaded sleeve plate, ensuring stable horizontal movement.

[0036] Example 2:

[0037] Specifically, the telescopic plate 25 is provided in two sets and symmetrically arranged on both sides of the threaded sleeve plate 24. The rolling shaft 26 is rotatably connected to one end of the telescopic plate 25, and the middle position of the rolling shaft 26 is slidably rotatably connected to the inner side of the guide groove 27.

[0038] In this embodiment, the telescopic plate 25 is made of aluminum alloy, and each set of telescopic plates contains a nested structure of 2 sections. The rolling shaft 26 is cylindrical and made of 40Cr steel, with both ends connected to the ends of the telescopic plate via bearings. The guide groove 27 is a U-shaped channel steel with a three-section slope of "downward-horizontal-upward" along its length. The telescopic plate, in conjunction with the rolling shaft, moves along the slope of the guide groove to realize the lifting and lowering of the fixed component, adapting to the depth of the groove.

[0039] Specifically, the upper side of the first connecting plate 31 is rotatably connected to the rolling shaft 26, and the second connecting plate 32 is provided in two sets and symmetrically arranged on both sides of the first connecting plate 31.

[0040] With this configuration, connecting plate 31 is an L-shaped steel plate, with its upper side rotatably connected to the middle of the rolling shaft 26 via a bushing; connecting plate 32 is a rectangular steel plate, symmetrically welded to both sides of connecting plate 31, with a sliding rod provided along its length on the inner side. The L-shaped connecting plates allow the fixing components to tilt with the rolling shaft, ensuring that the sheet metal is vertically immersed in the tank, and the double connecting plates enhance structural stability.

[0041] Example 3:

[0042] Specifically, the bidirectional threaded rod 33 is rotatably connected to the inner side of the connecting plate 32, one side of the clamping plate 34 is attached to one side of the sheet metal body 35, and the clamping plate 34 is slidably connected to the slide rod provided on the inner side of the connecting plate 32.

[0043] The bidirectional threaded rod 33 has half left-hand and half right-hand threads, is made of 45# steel, and is connected to the connecting plate 32 at both ends via bearings. The clamping plate 34 is a rectangular steel plate with a 3mm thick nitrile rubber pad attached to the inside. It is threaded to the bidirectional threaded rod in the middle and slidably connected to the slide rods on the connecting plate 32 on both sides. The bidirectional threaded rod drives the clamping plates to move in opposite directions. The rubber pads increase friction and prevent the sheet metal from slipping, making it suitable for sheet metal of different widths.

[0044] Specifically, the clamping plate 34 is provided in two sets and symmetrically arranged on both sides of the sheet metal body 35, and the fixing component 3 is located on the lower side of the guide groove 27.

[0045] In this embodiment, the distance between the two sets of clamping plates 34 is adjustable, and the fixing component 3 is located directly below the guide groove and aligned with the center of the electrophoresis treatment tank 4; when the fixing component 3 moves along the guide groove, the distance adjustment adapts to various sheet metal sizes, and the lifting stroke ensures that the sheet metal is completely immersed in or detached from the tank, guaranteeing the treatment effect.

[0046] In use, the sheet metal body 35 is placed between two sets of clamping plates 34. By rotating the bidirectional threaded rod 33, the clamping plates 34 move in opposite directions to fasten the sheet metal body 35. By starting the drive motor 22, the unidirectional threaded rod 23 is rotated, which moves the threaded sleeve 24, causing the rolling shaft 26 to rotate and slide inside the guide groove 27. When it moves to the inclined position, the rolling shaft 26 tilts downward, and at the same time, the telescopic plate 25 extends and retracts, causing the telescopic plate 25 to tilt downward and move into the pretreatment tank included in the electrophoresis treatment tank 4. By continuing to move, the rolling shaft 26 tilts upward and then tilts downward into the electrophoresis tank, and then moves into the cleaning tank to complete the electrophoresis operation.

[0047] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
