Description

Technical Field

[0001] This utility model relates to the technical field of rust prevention for castings, and in particular to a treatment device for rust prevention of castings. Background Technology

[0002] Rust prevention of castings involves forming a uniform and dense protective film on the surface of the casting to isolate it from corrosive media, thereby achieving long-term rust prevention.

[0003] In related technologies, existing rust prevention treatment devices for castings mostly adopt open oil tank immersion or simple spray structure. In actual use, the consumption of rust-preventive oil is large. After the parts are removed, they rely on gravity to drain naturally, resulting in serious waste of oil dripping and ineffective recycling, leading to high production costs. Secondly, the treatment effect is uneven. Complex casting cavities are prone to air bubbles and dead zones, while spraying has coverage blind spots. Thirdly, the working environment is harsh. The open structure causes oil and gas volatilization, which not only harms the health of workers but also poses a fire hazard. In addition, the ground is heavily polluted with oil. Manual operation and long draining time result in low production efficiency, which restricts the efficiency of rust prevention treatment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a rust prevention treatment device for castings, which adopts a fully enclosed pressure circulation system to soak and effectively eliminate rust-preventing dead corners of parts. Through forced oil discharge by air pressure and wind blowing, it realizes the active and efficient recovery and recycling of rust-preventing oil, thereby improving oil utilization and rust prevention effect.

[0006] To achieve the above objectives, this utility model proposes a rust prevention treatment device for castings, comprising a base, two symmetrically arranged support plates, and a storage-type rust prevention mechanism. The two symmetrically arranged support plates are mounted on the base. The storage-type rust prevention mechanism includes a storage box, a pressure box, two symmetrically arranged first driving devices, and a pressurizing component. The storage box is positioned between the two symmetrically arranged support plates. The pressure box is movably connected to the two symmetrically arranged support plates via the two symmetrically arranged first driving devices, and is located above and engaged with the storage box. The pressurizing component is mounted on the pressure box.

[0007] In addition, the rust prevention treatment device for castings proposed above according to this utility model may also have the following additional technical features: Specifically, a return pipe connects the storage box and the base.

[0008] Specifically, the pressurization assembly includes a second drive device, a third drive device, an inlet pipe, a first check valve, and a second check valve. The second drive device is mounted on the base, the first check valve is mounted on the pressure box and connected to the output end of the second drive device via a pipeline, the third drive device is mounted on the base, the inlet pipe is located at the input end of the third drive device and extends into the interior of the base, and the second check valve is mounted on the pressure box and connected to the output end of the third drive device via a pipeline.

[0009] Specifically, the bottom of the pressure box has multiple first through holes, and a first rubber valve is provided in each of the first through holes.

[0010] Specifically, the bottom of the storage box has multiple second through holes, and a second rubber flap is provided inside the second through holes. The inside of the storage box is provided with a filter screen, which is located above the second through holes.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The rust prevention treatment device for castings of this utility model adopts a fully enclosed pressure circulation system. The adjustable-height pressure box and the storage box are interlocked to achieve a fully enclosed structure during the soaking process. The soaking of the rust-preventive oil effectively eliminates the dead corners of the parts for rust prevention. Then, through forced oil discharge by air pressure and blow-by by wind, the active and efficient recovery and recycling of the rust-preventive oil are realized, which effectively reduces oil vapor volatilization and improves oil utilization and rust prevention effect.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention for a rust-prevention treatment device for castings.

[0017] like Figures 1-4 As shown, the rust prevention treatment device for castings according to this utility model embodiment may include a base 1, two symmetrically arranged support plates 2, and a storage-type rust prevention mechanism 3.

[0018] Two symmetrically arranged support plates 2 are mounted on the base 1.

[0019] Understandably, the base 1 can stably support the two symmetrically arranged support plates 2 and the storage-type rust prevention mechanism 3.

[0020] The storage-type rust prevention mechanism 3 includes a storage box 31, a pressure box 32, two symmetrically arranged first drive devices 33, and a pressurization component 34.

[0021] The storage box 31 is disposed between two symmetrically arranged support plates 2. The pressure box 32 is movably connected to the two symmetrically arranged support plates 2 through two symmetrically arranged first drive devices 33, and is located above the storage box 31 and is engaged with the storage box 31. The pressurization component 34 is disposed on the pressure box 32.

[0022] It should be noted that in the above embodiment, the first driving device 33 is a cylinder, and the extension and retraction ends of the two cylinders are stably connected to the pressure box 32, and are slidably engaged with the storage box 31 above the storage box 31 to realize the closing or opening adjustment of the storage box 31.

[0023] Specifically, during the actual rust prevention process, the relevant personnel placed the casting on the filter screen 313 inside the storage box 31 and filled the base 1 with rust-preventive oil. In the initial state, the pressure box 32 was at the highest point and separated from the storage box 31, which made it easier for the casting to be placed into the storage box 31.

[0024] During rust prevention treatment, the first drive device 33 is extended, the pressure box 32 moves down and closes to the storage box 31 with a certain gap. The third drive device 342 is then driven, and the inlet pipe 343 draws out the rust-preventive oil. The rust-preventive oil is then unidirectionally delivered to the pressure box 32 through the connected pipeline and the second one-way valve 345. The pressure of the rust-preventive oil in the pressure box 32 gradually increases, opening the first rubber valve 3211 and spraying the rust-preventive oil downward from the first through hole 321. Under the sealing effect of the second rubber valve 3121, the rust-preventive oil is stored in the storage box 31. The accumulated rust-preventive oil comes into contact with the casting, achieving immersion rust prevention for the parts. The first drive device 33 is then driven to extend again, and the pressure box 32 moves down further and is fastened to the upper part of the storage box 31, so that the casting is in a relatively sealed environment.

[0025] When removing the rust-preventive oil, the second drive device 341 is driven to draw in external air and pump it into the pressure box 32 through the pipeline and the first one-way valve 344 in sequence. This squeezes out the rust-preventive oil in the pressure box 32. At the same time, the air enters the storage box 31, increasing the air pressure inside the storage box 31 and squeezing the rust-preventive oil in the storage box 31 downwards. The rust-preventive oil is discharged through the second through hole 312 and then flows back into the base 1 through the return pipe 311.

[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, a return pipe 311 connects the storage box 31 and the base 1. It should be noted that the return pipe 311 described in this embodiment is used for closed-loop recovery of rust-preventive oil, reducing oil vapor evaporation and floating, while preventing oil splashing.

[0027] In one embodiment of this utility model, such as Figures 2-4 As shown, the pressurization assembly 34 includes a second drive device 341, a third drive device 342, an inlet pipe 343, a first check valve 344, and a second check valve 345.

[0028] The second drive device 341 is mounted on the base 1, the first one-way valve 344 is mounted on the pressure box 32 and is connected to the output end of the second drive device 341 via a pipeline, the third drive device 342 is mounted on the base 1, the inlet pipe 343 is mounted on the input end of the third drive device 342 and extends into the interior of the base 1, and the second one-way valve 345 is mounted on the pressure box 32 and is connected to the output end of the third drive device 342 via a pipeline.

[0029] It should be noted that the second driving device 341 proposed in the above embodiment is an air pump, and the third driving device 342 is a water pump. The output ends of the air pump and the water pump are respectively connected to the first one-way valve 344 and the second one-way valve 345 through pipes. During the oil or gas supply process, the internal pressure of the pressure box 32 causes the other side of the pipe to flow back.

[0030] In one embodiment of this utility model, such as Figures 2-4 As shown, the bottom of the pressure box 32 has multiple first through holes 321, and a first rubber valve 3211 is provided in the first through hole 321.

[0031] It should be noted that the multiple first through holes 321 described in this embodiment are opened on the bottom wall of the pressure box 32, and under the action of the first rubber valve 3211, the oil or gas is pressurized and sprayed out.

[0032] In one embodiment of this utility model, such as Figures 2-4 As shown, the bottom of the storage box 31 has multiple second through holes 312, and a second rubber flap 3121 is provided inside the second through hole 312. The inside of the storage box 31 is provided with a filter screen 313, which is located above the second through hole 312.

[0033] It should be noted that the multiple second through holes 312 described in this embodiment are opened on the bottom wall of the storage box 31 and sealed by the second rubber flap 3121. When the pressure box 32 is not fastened and no pressure is applied, the storage box 31 can accumulate rust-preventive oil, thereby immersing the parts carried by the storage box 31 in rust prevention. If the pressure box 32 is fastened on the storage box 31 and air is injected into it, the rust-preventive oil can be squeezed downward and flow back to the base 1 for recycling.

[0034] In summary, the rust prevention treatment device for castings based on this utility model adopts a fully enclosed pressure circulation system, which soaks and effectively eliminates dead corners for rust prevention of parts. Through forced oil discharge by air pressure and wind blowing, it realizes the active and efficient recovery and recycling of rust-preventive oil, thereby improving oil utilization and rust prevention effect.
