Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to a phosphating treatment device for stainless steel plate surface. Background Technology

[0002] Metal phosphating forms a phosphating film on the metal surface, preventing the metal from being viewed from above. During the phosphating process, slag deposits are generated. If these deposits accumulate on the metal surface, they will affect the contact between the metal and the phosphating solution, thus impacting the phosphating reaction.

[0003] In existing metal phosphating processes, hangers are often placed in the phosphating tank. However, these hangers have a single function and cannot agitate the phosphating solution, which can lead to sediment buildup that affects the metal phosphating process and compromises the quality of the metal treatment. Utility Model Content

[0004] The purpose of this invention is to provide a phosphate treatment device for stainless steel plate surface in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a phosphate treatment device for stainless steel plate surface, including a U-shaped plate, wherein several horizontal strip grooves are provided on opposite sides of the inner wall of the U-shaped plate, and a steel plate is slidably connected between two corresponding strip grooves.

[0007] The U-shaped plate is fixedly connected to a limit frame assembly to limit the steel plate on both sides that do not correspond to the U-shaped plate, so as to prevent the steel plate from detaching from the strip groove.

[0008] The U-shaped plate is rotatably connected to a connecting frame for connecting with a lifting device;

[0009] A swinging component is fixedly connected to the connecting frame for swinging the U-shaped plate.

[0010] Using the above-mentioned stainless steel plate surface phosphating treatment device, the steel plate to be phosphated is placed on a U-shaped plate. The U-shaped plate and the limiting frame assembly can fix the steel plate. It is connected to the connecting frame through a lifting device. The lifting device is used to immerse the steel plate in the phosphating solution. Then, the U-shaped plate is swung back and forth by the swinging assembly. The U-shaped plate drives the steel plate to swing back and forth, which can agitate the phosphating solution and prevent the accumulation of slag on the surface of the steel plate. This ensures that the steel plate and the phosphating solution are in full contact. After phosphating, the U-shaped plate and the steel plate are lifted out of the phosphating solution by the lifting device. Then, the swinging assembly tilts the steel plate to one side so that the phosphating solution on the steel plate can flow down quickly.

[0011] Preferably, the limiting frame assembly includes a crossbeam, which is fixedly connected between two side plates of the U-shaped plate. A rectangular sleeve is fixedly connected to the crossbeam, and two connecting plates are inserted into the rectangular sleeve. Two spring pins are fixedly connected to the rectangular sleeve, and the two spring pins pass through the two connecting plates respectively. A fixing rod is vertically fixedly connected to the connecting plate, and the fixing rod contacts the side of the steel plate.

[0012] Preferably, the connecting plate has a through hole, and the spring pin passes through the rectangular sleeve and is inserted into the through hole.

[0013] Preferably, there is a gap between two adjacent steel plates.

[0014] Preferably, both sides of the U-shaped plate are fixedly connected to a fixed shaft, and the two fixed shafts are rotatably connected to both sides of the connecting frame.

[0015] Preferably, the fixed shaft is located at the center point of the side of the U-shaped plate, and the center point of the steel plate is on the same vertical line as the fixed shaft.

[0016] Preferably, the swing assembly includes a fixed base, which is fixedly connected to a connecting frame. Two rotating shafts are rotatably connected to the fixed base, and sprockets are fixedly connected to both rotating shafts. The two sprockets are connected by a chain drive. A winding wheel is fixedly connected to each rotating shaft, and a pull rope is wound on the winding wheel. The two pull ropes are fixedly connected to both sides of the U-shaped plate, and the other end of the pull rope is fixedly connected to the winding wheel. A torque motor is fixedly connected to the connecting frame, and the output shaft of the torque motor is fixedly connected to the end of any one of the rotating shafts.

[0017] Preferably, the connecting frame is fixedly connected with multiple fixing rings.

[0018] The beneficial effects are:

[0019] 1. The steel plate can be fixed by the U-shaped plate and the limiting frame assembly. The oscillating component can swing the U-shaped plate back and forth to stir the phosphating solution, prevent the slag from accumulating on the surface of the steel plate, and ensure that the steel plate and the phosphating solution are in full contact to ensure the quality of metal phosphating treatment. After phosphating, the oscillating component can be used to tilt the steel plate to one side so that the phosphating solution on the steel plate can flow down quickly to facilitate subsequent processing steps and improve processing efficiency.

[0020] 2. The U-shaped plate can stack several steel plates, which can increase the number of steel plates in the phosphate bath with limited depth, thereby increasing the number of steel plates processed at one time. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-5 As shown, this utility model provides a phosphate treatment device for stainless steel plate surface, including a U-shaped plate 1. Several horizontal strip grooves 2 are opened on the opposite surfaces of the inner wall of the U-shaped plate 1, and a steel plate 3 is slidably connected between two corresponding strip grooves 2.

[0031] The U-shaped plate 1 is fixedly connected to the limit frame assembly 4 for limiting the two sides of the steel plate 3 that do not correspond to the U-shaped plate 1, so as to prevent the steel plate 3 from separating from the strip groove 2;

[0032] A connecting frame 5 for connecting to a lifting device is rotatably connected to the U-shaped plate 1;

[0033] A swing assembly 7 is fixedly connected to the connecting frame 5 for swinging the U-shaped plate 1.

[0034] As an optional implementation, the limiting frame assembly 4 includes a crossbeam 8, which is fixedly connected between the two side plates of the U-shaped plate 1. A rectangular sleeve 9 is fixedly connected to the crossbeam 8, and two connecting plates 11 are inserted into the rectangular sleeve 9. Two spring pins 10 are fixedly connected to the rectangular sleeve 9, and the two spring pins 10 pass through the two connecting plates 11 respectively. A fixing rod 12 is vertically fixedly connected to the connecting plate 11, and the fixing rod 12 contacts the side of the steel plate 3.

[0035] The spring pin 10, in conjunction with the rectangular sleeve 9, can fix the connecting plate 11 onto the crossbeam 8, making installation and disassembly very convenient.

[0036] By using multiple fixing rods 12 to block both sides of the steel plate 3, the steel plate 3 can be prevented from detaching from the U-shaped plate 1.

[0037] The connecting plate 11 has a through hole 14, and the spring pin 10 passes through the rectangular sleeve 9 and is inserted into the through hole 14.

[0038] There is a gap between two adjacent steel plates 3 to allow for the flow of phosphating solution.

[0039] Both sides of the U-shaped plate 1 are fixedly connected to fixed shafts 13, and the two fixed shafts 13 are rotatably connected to both sides of the connecting frame 5 respectively.

[0040] The fixed shaft 13 is located at the center point of the side of the U-shaped plate 1, and the center point of the steel plate 3 is on the same vertical line as the fixed shaft 13. This design allows the U-shaped plate 1 to be in a horizontal state, reducing the load on the swing assembly 7.

[0041] The swing assembly 7 includes a fixed base 16, which is fixedly connected to the connecting frame 5. Two rotating shafts 17 are rotatably connected to the fixed base 16. A sprocket 20 is fixedly connected to each of the two rotating shafts 17, and the two sprockets 20 are connected by a chain 21. A winding wheel 18 is fixedly connected to the rotating shaft 17, and a pull rope 19 is wound on the winding wheel 18. The two pull ropes 19 are fixedly connected to both sides of the U-shaped plate 1, and the other end of the pull rope 19 is fixedly connected to the winding wheel 18. A torque motor 15 is fixedly connected to the connecting frame 5, and the output shaft of the torque motor 15 is fixedly connected to the end of any one of the rotating shafts 17.

[0042] The torque motor 15, in conjunction with two sprockets 20, a rotating shaft 17, and a chain 21, can simultaneously rotate two winding wheels 18. One winding wheel 18 releases the pull rope 19, while the other winding wheel 18 winds up the pull rope 19. The two pull ropes 19, in conjunction with the fixed shaft 13, can tilt the U-shaped plate 1 to a specified side. By switching the rotation of the torque motor 15 in both directions, the U-shaped plate 1 can be made to swing back and forth.

[0043] The swinging component 7 does not need to swing the U-shaped plate 1 too much. The steel plate 3 only needs to swing slightly to stir the phosphating solution. Furthermore, the slight swinging and the stacking of the steel plates 3 can reduce the amount of phosphating solution used in the phosphating tank.

[0044] Multiple fixing rings 6 are fixedly connected to the connecting frame 5. The fixing rings 6 are set to facilitate connection with the hook of the lifting device.

[0045] Using the above structure, the steel plate 3 to be phosphated is placed on the U-shaped plate 1. The U-shaped plate 1 and the limiting frame assembly 4 can fix the steel plate 3. It is connected to the connecting frame 5 through the lifting device. The steel plate 3 is immersed in the phosphate solution by the lifting device. Then, the U-shaped plate 1 is swung back and forth by the swing assembly 7. The U-shaped plate 1 drives the steel plate 3 to swing back and forth. This can stir the phosphate solution and prevent the sediment from accumulating on the surface of the steel plate 3, so that the steel plate 3 can fully contact the phosphate solution. After phosphated, the U-shaped plate 1 and the steel plate 3 are lifted out of the phosphate solution by the lifting device. Then, the steel plate 3 is tilted to one side by the swing assembly 7 so that the phosphate solution on the steel plate 3 can flow down quickly.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
