Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cage cleaning and rust prevention, and particularly relates to a cage cleaning and rust prevention production line and a working method. BACKGROUND

[0002] Metal powder, oil stains and magnetic particles are left on the surface of a bearing cage after stamping processing, and the bearing cage can enter the assembly link only after three steps of demagnetization, cleaning and rust prevention. The existing cage cleaning production line generally adopts a series layout of "linear transmission mechanism + demagnetizer + spray cleaning chamber + air cutting drying chamber + rust prevention spray chamber", and a typical process flow is as follows: A worker or a mechanical hand places the cage on a conveying roller, and the cage sequentially passes through a demagnetizing device to eliminate residual magnetism; then the cage is conveyed to a high-pressure spray area to remove metal chips and oil stains with cleaning liquid; the surface liquid is blown away by an air knife; the cage is covered with rust-proof oil or water-based rust inhibitor in a rust prevention spray area; and finally, the cage is dried and discharged.

[0003] However, the above-mentioned device has the following common defects in actual operation: 1. Liquid pollution; only an air knife or a simple curtain is used to isolate the cleaning chamber and the rust prevention chamber, and the atomized cleaning liquid and the rust prevention liquid can penetrate each other within 0.2 s to 0.5 s, which causes the cleaning liquid to be polluted by the rust-proof oil, the pH value to decrease, and the decontamination capacity to decrease, and the tank needs to be frequently replaced; at the same time, the rust prevention liquid is mixed with water and metal soap, the flash point is reduced, the rust prevention film thickness is uneven, and yellow spots or oil spots appear subsequently.

[0004] 2. Secondary attachment of metal powder; although the metal powder after demagnetization is flushed away from the surface of the cage by the spray liquid, the powder-containing liquid collected at the bottom of the spray chamber is recycled again under the action of a reflux pump. When the liquid flow rate is less than 0.5 m / s, the powder with a particle size of ≤20 μm is not completely settled, and is sprayed again onto the cage by the nozzle, forming a vicious cycle of "cleaning-recontamination". SUMMARY

DETAILED DESCRIPTION

[0023] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0024] Example 1 In a typical embodiment of the present application, referring to Figures 1-4 , a retainer cleaning and rust prevention production line includes a first rack 1 and a second rack 2. The first rack 1 and the second rack 2 are arranged in a split manner to prevent liquid from mixing between the cleaning process and the rust prevention process. Each set of racks is provided with a spray station. Each set of racks is provided with a liquid collecting hopper and a liquid storage tank from top to bottom corresponding to the spray station. The bottom end of the liquid collecting hopper is provided with a filter basket. The liquid storage tank of the first rack is provided with baffles with openings arranged alternately. The liquid storage tank is also provided with multiple magnets. The spray station is connected to the liquid storage tank through a pipeline and a pump. By arranging corresponding filter structures, the secondary adhesion of metal powder to the retainer is prevented.

[0025] As shown in Figure 1 , the first rack and the second rack are arranged from left to right according to the moving direction of the retainer. The first rack and the second rack are independently arranged in a split manner.

[0026] Each set of racks is provided with a housing and a conveyor belt. The conveyor belt penetrates through the corresponding housing. The first rack 1 is provided with a first housing and a first conveyor belt 3. The second rack 2 is provided with a second housing and a second conveyor belt 4. Each set of housings is provided with an inlet and an outlet for the conveyor belt to pass through, as shown in Figure 1 .

[0027] The first conveying belt 3 has a first transmission shaft and a second transmission shaft 31 at two ends respectively, and the second conveying belt 4 has a third transmission shaft 41 and a fourth transmission shaft at two ends respectively. The first transmission shaft is provided with two groups of first sprockets 11, the second transmission shaft is provided with two groups of second sprockets 12, the third transmission shaft is provided with two groups of third sprockets 13, and the fourth transmission shaft is provided with two groups of fourth sprockets 14. The first transmission shaft and the second transmission shaft 31 are located outside the first shell, and the third transmission shaft 41 and the fourth transmission shaft are located outside the second shell.

[0028] The first transmission shaft and the second transmission shaft 31 are provided with two groups of chains through the sprockets, and the first conveying belt 3 is arranged between the two groups of chains. The second conveying belt 4 is arranged on the third transmission shaft 41 and the fourth transmission shaft in the same way. The conveying belt is in a hollow form, which facilitates the spraying of the nozzles from the upper and lower sides of the conveying surface of the conveying belt.

[0029] In a preferred example, the conveying belt can also be replaced by connecting rods. A plurality of parallel connecting rods are connected between the two groups of chains, which also does not affect the spraying of the nozzles from the upper and lower sides.

[0030] As shown in Figure 1 , a driving sprocket is arranged at the end of the fourth transmission shaft. A motor 10 is arranged in the second rack. The motor 10 drives the driving sprocket on the fourth transmission shaft through the driving chain 16 to drive the second conveying belt.

[0031] As shown in Figure 1 and Figure 2 , the two conveying belts are arranged horizontally, and the two conveying belts are connected through the transition chain 9 to realize the linkage of the conveying belts. The third transmission shaft is arranged close to and lower than the second transmission shaft, so that the transition chain 9 is arranged in a tilted manner after installation.

[0032] The same end of the second transmission shaft 31 and the third transmission shaft 41 is provided with a transition sprocket 32 and a transition sprocket 41, and the transition sprocket 32 and the transition sprocket 41 are matched through the transition chain 9.

[0033] Through the arrangement of the transition chain 9, while preventing the mixing of cleaning liquid and rust-proof liquid by using the split type first rack and second rack, one motor 10 can drive the first conveying belt 3 and the second conveying belt 4 to synchronize transmission at the same time, without the need to arrange two groups of motors.

[0034] As shown in Figure 1 , the shell of the first rack is sequentially provided with a spraying rough cleaning station, a spraying rinsing station and a first air cutting station; and the shell of the second rack is sequentially provided with a spraying rust-proof station and a second air cutting station.

[0035] The spraying stations (the spraying rough cleaning station 51, the spraying rinsing station 52 and the spraying anti-rust station 53) each comprise two groups of nozzles, which are correspondingly arranged on the upper and lower sides of the conveying belt conveying surface, so as to spray and clean the retainer from the upper and lower directions.

[0036] Each group of nozzles is provided with a plurality of nozzles, and each group of nozzles is integrated on a spray pipe, which is mounted on the shell through a fixing structure and connected to the pump 21 through a pipeline.

[0037] In the first rack 1, a first collecting tank 61 is arranged below the spraying rough cleaning station 51, and a first liquid storage tank 71 is arranged below the first collecting tank 61.

[0038] In the first rack 1, a second collecting tank 62 is arranged below the spraying rinsing station 52, and a first liquid storage tank 72 is arranged below the second collecting tank 62.

[0039] In the second rack 2, a third collecting tank 63 is arranged below the spraying anti-rust station 53, and a third liquid storage tank 73 is arranged below the third collecting tank 63.

[0040] A partition is arranged between the spraying rough cleaning station and the spraying rinsing station in the first shell, the partition is connected to the first shell, the bottom end of the partition is located above the conveying belt, the partition separates the two groups of nozzles in the first shell, and the first shell is divided into two spraying chambers, so that kerosene is prevented from being mixed between the two stations.

[0041] It can be understood that the arrangement of the partition does not affect the movement of the retainer on the conveying belt.

[0042] In the embodiment, the medium in the liquid storage tank in the first rack 1 is kerosene, and the medium in the liquid storage tank in the second rack is anti-rust oil.

[0043] In the spraying rough cleaning station 51, the high-pressure nozzles spray kerosene to spray and clean the metal powder and impurities on the surface of the retainer, and most of the metal powder is washed away from the retainer. The partition can isolate most of the oil mist in the spraying rough cleaning station 51 to prevent liquid mixing. In the spraying rinsing station 52, kerosene is further sprayed by the high-pressure nozzles to perform rinsing, so as to ensure good cleaning effect and prevent metal powder from remaining on the retainer.

[0044] The air cutting station is correspondingly arranged on the top of the shell, the air cutting station is provided with an air pump, the first air pump 15 is arranged on the first shell and located downstream of the spraying rinsing station 52, after two times of spraying and cleaning, the first air pump 15 blows air to blow off the excess liquid on the retainer, and also has the effect of saving oil.

[0045] The first shell is also arranged with an oil mist treatment machine 8 for collecting the diffused oil mist and saving oil. The oil mist treatment machine 8 is connected to the first liquid storage tank 71 through a pipeline with a filter, and the collected oil is filtered and then re-enters the first liquid storage tank 71 for use.

[0046] The liquid collecting bucket in the first shell is used to collect the oil of the corresponding station. The bottom of the liquid collecting bucket is provided with a filter basket 19 for filtering the metal powder to prevent the metal powder from entering the first liquid storage tank 71. A plurality of magnets are arranged in the filter basket 19 for adsorbing the metal powder flowing through the position of the filter basket. The shape and size of the magnets are determined according to the size of the filter basket, and the magnets are uniformly arranged in the filter basket.

[0047] The baffles 20 in the embodiment are vertically and parallelly arranged inside the liquid storage tank. Three baffles can be arranged along the length direction of the liquid storage tank. The openings on each baffle are not on the same side, which extends the flow path of the oil. The baffles divide the liquid storage tank into different grooves. The openings on the baffles have a set distance from the bottom surface of the liquid storage tank, which can prevent the metal powder deposited on the bottom of the liquid storage tank from entering the next groove. Magnets are installed on the bottom of the liquid storage tank to adsorb the metal powder and prevent the metal powder from being pumped out and sprayed onto the holder again.

[0048] In a preferred example, a filter screen is arranged between the baffles to further filter the metal powder. A filter is also arranged on the pipeline between the pump and the liquid storage tank to prevent the metal powder from being pumped to the spray head.

[0049] The pump 21 is connected to the top of the liquid storage tank through a pipeline to pump kerosene or rust-proof oil from the liquid storage tank to the spray head to realize the cyclic spraying of the oil.

[0050] Through the arrangement of the filter basket 19, the baffle 20 with openings, the magnets, the filter screen, and the filter, five-stage filtration of the metal powder during the cyclic spraying of the oil is realized, which effectively guarantees the cleaning effect.

[0051] As shown in Figure 1 The holder enters the second shell after coming out of the first shell. The rust-proof oil spraying station sprays rust-proof oil on the holder to complete the rust-proof process. The excess rust-proof oil flows into the third liquid collecting bucket and then flows into the third liquid storage tank 73.

[0052] The second air pump 17 is arranged at the top of the second shell and downstream of the rust-proof oil spraying station to blow air on the holder sprayed with the rust-proof oil to blow off the excess rust-proof oil from the holder. Then the holder is sent out of the outlet of the second shell and then discharged.

[0053] It can be understood that the number of baffles and magnets in the third liquid tank 73 can be reduced or not set according to actual conditions, because most of the metal powder is left in the spray roughing station, a small part is left in the spray rinsing station, and there is basically no metal powder in the spray rust prevention station.

[0054] As shown in Figure 4 The first liquid tank 71 and the second liquid tank 72 are connected with the first liquid inlet pipeline 22 for adding kerosene into the liquid tank, and the third liquid tank 73 is connected with the second liquid inlet pipeline 23 for adding rust-proof oil into the liquid tank. The three liquid tanks are also provided with overflow pipelines 24 and liquid discharge pipelines 25, and the overflow pipelines 24 and the liquid discharge pipelines 25 of the first liquid tank 71 and the second liquid tank 72 are communicated, and the overflow pipelines 24 and the liquid discharge pipelines 25 of the third liquid tank 73 are communicated.

[0055] It can be understood that the related valves and pressure gauges and the like structures on the pipeline of the embodiment are prior art, and will not be described in detail. A control cabinet 18 is arranged on the production line for controlling the entire production line work.

[0056] Embodiment two A working method of the retainer cleaning and rust prevention production line, using the retainer cleaning and rust prevention production line of the embodiment one, comprising the following steps: The retainer after demagnetization enters the inside of the shell of the first rack 1 under the conveying of the first conveying belt 3, first passes through the spray roughing station, and the metal impurities on the surface are washed away through the high-pressure spray head. The kerosene carrying the metal powder is collected into the first liquid collecting hopper 61, and then flows into the first liquid tank 71, and the metal powder is filtered on the filter basket 19.

[0057] The retainer continues to move on the first conveying belt, then passes through the spray rinsing station for further rinsing, then passes through the air cutting station, and the first air pump 15 blows away the excess kerosene on the surface of the retainer; the kerosene in the spray rinsing station is collected in the second liquid tank 72. The partition effectively isolates the spray rinsing station and the spray cleaning station to prevent liquid mixing and ensure that most of the metal powder is left in the spray cleaning station. The oil mist treatment machine 8 collects the oil mist for recycling.

[0058] The retainer comes out of the shell of the first rack and enters the second conveying belt under the action of the transition chain, and the distance between the second transmission shaft and the third transmission shaft is small enough to allow the retainer to smoothly transition.

[0059] The retainer then enters the shell of the second rack, sprays rust-proof oil after passing through the spray rust prevention station, continues to pass through the second air pump to blow away the rust-proof oil on the surface, and then is discharged after coming out of the shell of the second rack.

[0060] The above merely provides the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the principles and technical scope of the present application shall fall into the scope of the present application.
