Description

Technical Field

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

[0002] A casting rust prevention device is a specialized piece of equipment or system used to prevent rust on the surface of metal castings during casting, machining, or storage. Its core function is to isolate the casting from contact with air and moisture by applying rust-preventive oil, rust inhibitor, or other protective layers, preventing oxidation and rusting, thereby extending the casting's shelf life and service life.

[0003] In related technologies, rust prevention devices for castings employ methods such as manual oiling, simple metering mechanisms, and static immersion. Among these, manual oiling devices rely on manual operation of brushes or spray guns, controlling the amount of oil through experience, and lack metering functionality. Simple metering mechanisms use gravity dripping or fixed-volume oil cups, controlling the amount of oil over time, but this method has low precision and is easily affected by oil viscosity. Static immersion rust prevention involves directly immersing the casting in an oil bath, resulting in significant oil waste and difficulty in controlling the uniformity of the oil film.

[0004] In practical applications, the aforementioned devices are difficult to adapt to the oil requirements of different small-sized castings, have poor quantitative accuracy, and the casting surfaces are uneven. Traditional oiling methods are prone to problems such as missed coating, local oil accumulation, or excessive oil application, which increases costs and pollutes the environment. They also increase manual intervention and labor intensity, resulting in low efficiency in rust prevention treatment of castings. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a casting anti-rust device with quantitative oil application. It adopts precise oil metering, is not affected by oil viscosity, and improves the uniformity of oil application on the casting surface by friction and forcing the casting to roll, avoiding manual touch-up, reducing the labor intensity of workers, and effectively improving the anti-rust efficiency of castings.

[0007] To achieve the above objectives, this utility model proposes a casting rust prevention device with quantitative oil application, comprising a support cylinder, an oil application mechanism, and a quantitative extraction mechanism. The oil application mechanism is rotatably connected to the support cylinder, and the quantitative extraction mechanism includes an oil storage box, a support frame, a first drive mechanism, and a diversion component. The oil storage box is disposed on the support cylinder, the first drive mechanism is disposed on the support cylinder via the support frame, and the diversion component is disposed between the first drive mechanism and the support cylinder.

[0008] This utility model discloses a casting rust prevention device with quantitative oil application. It is designed for oil application treatment of the outer surface of castings of different small sizes. It adopts volumetric precision quantitative method and achieves precise measurement through a first one-way valve (oil inlet) and a second one-way valve (oil outlet). The oil volume is controlled by the piston stroke and is not affected by the viscosity of the oil.

[0009] During the oiling process, the casting is rotated and forced to roll by friction against the inner wall of the mixing chamber. Combined with the flexible friction cylinder, this overcomes the dead corners of oiling on the complex surface of the casting, improves the uniformity of the oil film, and dynamically mixes with the casting. This avoids manual touch-up and prevents the rust-preventive oil from polluting the environment and being wasted. It effectively reduces the labor intensity of workers and improves the rust prevention efficiency of the casting.

[0010] In addition, the casting rust prevention device with quantitative oil application proposed above according to this utility model may also have the following additional technical features:

[0011] Specifically, the support cylinder is provided with a stirring chamber, and the support cylinder is provided with multiple pressure chambers. Multiple sets of through holes are opened between the multiple pressure chambers and the stirring chamber, and rubber valves are provided in the through holes.

The measuring cylinder is disposed between the support frame and the support tube, the first driving device is disposed on the support frame, the piston is movably connected to the measuring cylinder through the first driving device, the first one-way valve is disposed between the measuring cylinder and the oil reservoir, and the second one-way valve is disposed on the measuring cylinder.

[0013] Specifically, the diversion assembly includes multiple connecting pipes and a diversion box, wherein the diversion box is disposed on the second one-way valve, and the multiple connecting pipes are disposed on the diversion box and are respectively connected to the multiple pressure chambers.

[0014] Specifically, the oiling mechanism includes a second driving device, a rotating rod, a connecting plate, and multiple partitions.

Detailed Implementation

[0024] 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.

[0025] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention of a casting rust prevention device with a quantitative oiling method.

[0026] like Figures 1-5 As shown, the casting rust prevention device with quantitative oiling according to the present invention may include a support cylinder 1, an oiling mechanism 2, and a quantitative extraction mechanism 3.

[0027] The oiling mechanism 2 is rotatably connected to the support cylinder 1.

[0028] It should be noted that the support cylinder 1 can stably support the oiling mechanism 2 and the quantitative extraction mechanism 3. The support cylinder 1 can accommodate small-sized castings. At the same time, the quantitative extraction mechanism 3 can stably transport and spray the extracted rust-preventive oil into the support cylinder 1. The end of the support cylinder 1 is hinged with a cover plate for opening and closing the mixing chamber 11 and for dust prevention.

[0029] The quantitative extraction mechanism 3 includes an oil storage box 31, a support frame 32, a first drive mechanism 33, and a diversion component 34.

[0030] The oil storage box 31 is mounted on the support cylinder 1, the first drive mechanism 33 is mounted on the support cylinder 1 via the support frame 32, and the diversion component 34 is mounted between the first drive mechanism 33 and the support cylinder 1.

[0031] It should be noted that a cover plate is hinged on the oil storage box 31 to prevent rust and dust. The support frame 32 stably supports the first drive mechanism 33. The first drive mechanism 33 quantitatively extracts the rust-preventive oil and distributes it evenly into each pressure chamber 12 using the diversion component 34.

[0032] Specifically, during the actual oiling process, the relevant personnel filled the oil storage box 31 with anti-rust oil, opened the end cover of the support cylinder 1, placed the small casting into the mixing chamber 11, and fastened the cover to seal the mixing chamber 11. In the initial state, none of the parts of the first drive mechanism 33 were opened.

[0033] When taking a fixed amount of oil, the first drive mechanism 33 extracts the rust-preventive oil from the oil storage box 31 and pumps it into the diversion component 34. The diversion component 34 evenly distributes the oil into the support cylinder 1. Then, the oiling mechanism 2 drives the small casting to flip inside the support cylinder 1, which improves the uniformity of oiling on the surface of the casting, avoids manual touch-up, reduces the labor intensity of workers, and effectively improves the rust prevention efficiency of the casting.

[0034] In one embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the support cylinder 1 is provided with a stirring chamber 11, and the support cylinder 1 is provided with multiple pressure chambers 12. Multiple sets of through holes 13 are opened between the multiple pressure chambers 12 and the stirring chamber 11, and rubber valves 131 are provided in the through holes 13.

[0035] It should be noted that the pressure chamber 12 is connected to the stirring chamber 11. The first driving device 331 pumps the rust-preventive oil to the pressure chamber 12, so that the rust-preventive oil is initially dispersed. At the same time, the stirring chamber 11 is filled with small-sized castings, which are turned over by the oiling mechanism 2, so that the rust-preventive oil is evenly distributed in the stirring chamber 11. Multiple sets of through holes 13 are arranged in a ring with equal spacing to improve the uniformity of the rust-preventive oil distribution. The rubber valve 131 increases the spray pressure of the rust-preventive oil.

[0036] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the first drive mechanism 33 includes a first drive device 331, a measuring cylinder 332, a piston 333, a first check valve 334, and a second check valve 335.

[0037] The measuring cylinder 332 is disposed between the support frame 32 and the support cylinder 1. The first driving device 331 is disposed on the support frame 32. The piston 333 is movably connected to the measuring cylinder 332 through the first driving device 331. The first one-way valve 334 is disposed between the measuring cylinder 332 and the oil storage box 31. The second one-way valve 335 is disposed on the measuring cylinder 332.

[0038] It should be noted that the first driving device 331 proposed in the above embodiment adopts a cylinder. The piston 333 is driven to move up and down by the extension end of the cylinder. The piston 333 is made of rubber. When the piston 333 rises, it creates a negative pressure in the measuring cylinder 332. The oil enters the measuring cylinder 332 through the first one-way valve 334. When the piston 333 falls, the piston 333 squeezes the oil and delivers it to the diversion assembly 34 through the second one-way valve 335.

[0039] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the diversion assembly 34 includes multiple connecting pipes 341 and a diversion box 342.

[0040] The flow divider box 342 is mounted on the second check valve 335, and multiple connecting pipes 341 are mounted on the flow divider box 342 and are respectively connected to multiple pressure chambers 12.

[0041] It should be noted that the flow divider box 342 is connected to the second check valve 335. The flow divider box 342 is used to divide the squeezed oil into multiple connecting pipes 341 and enter the pressure chamber 12, thereby improving the uniformity of the distribution of the rust-preventive oil.

[0042] In one embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the oiling mechanism 2 includes a second drive device 21, a rotating rod 22, a connecting plate 23, and multiple partition nets 24.

[0043] The second drive device 21 is mounted on the support cylinder 1, the rotating rod 22 is rotatably connected to the stirring chamber 11 through the connecting plate 23 and is connected to the second drive device 21, and multiple partitions 24 are mounted on the rotating rod 22.

[0044] It should be noted that the second driving device 21 proposed in the above embodiment adopts a rotary motor, and the connecting plate 23 is set at the inlet and outlet of the mixing chamber 11. When the rotary motor drives the rotating rod 22 to rotate, it drives multiple partitions 24 to rotate synchronously. At the same time, the partitions 24 divide the mixing chamber 11 into multiple areas for storing small-sized castings, improving the flexibility of casting flipping and better contact with the friction cylinder 111.

[0045] In one embodiment of this utility model, such as Figure 5 As shown, a friction cylinder 111 is provided inside the stirring chamber 11, and a brush 112 is provided inside the stirring chamber 11.

[0046] It should be noted that the friction cylinder 111 is made of sponge material, which allows the friction cylinder 111 to absorb the rust-preventive liquid. When the small casting is turned over, the friction with the casting is increased. The flexible and deformable friction cylinder 111 can make the rust-preventive liquid evenly applied to the surface of the casting. The brush 112 and the through hole 13 are arranged in an alternating manner. When the casting is turned over, it comes into contact with the surface of the casting, which further improves the uniformity of the application of the rust-preventive oil.

[0047] In summary, the casting rust prevention device with quantitative oil application according to this utility model embodiment adopts precise oil metering, is not affected by oil viscosity, and improves the uniformity of oil application on the casting surface by friction and forcing the casting to roll, avoiding manual touch-up, reducing the labor intensity of workers, and effectively improving the rust prevention efficiency of castings.
