Description

Technical Field

[0001] This application relates to the field of bolt processing technology, and more specifically, to an automatic degreasing device for bolts after cold heading. Background Technology

[0002] In the production and manufacturing process of bolts, cold heading is widely used because it can achieve plastic deformation of metal blanks, ensure the mechanical properties of bolts and has high material utilization. After the bolts are cold-headed, an oil removal device is needed to remove the oil stains remaining on the surface and in the gaps.

[0003] In related technologies, for example, patent CN222659432U provides an automatic degreasing device for bolts after cold heading. This device includes a support frame, an degreasing tank, a cleaning agent mixing component, a water tank, a cleaning mechanism, a collection mechanism, and a collection box. The degreasing tank is fixedly connected to the support frame, and the cleaning agent mixing component is fixedly connected to the top of the degreasing tank, wherein the cleaning agent mixing component includes a water tank. The cleaning mechanism is fixedly connected inside the degreasing tank, and the collection mechanism is fixedly connected to the bottom of the degreasing tank, wherein the collection mechanism includes a collection box. Through the above technical solution, the problem of grease accumulation in the oil suction machine in the prior art requiring manual opening of the absorber to pour out the grease and clean the absorber is solved. This process is time-consuming and laborious, increasing unnecessary workload. Furthermore, cleaning the absorber during the bolt degreasing process also affects the efficiency of bolt degreasing.

[0004] While the existing technical solutions described above have solved the problems mentioned in the background, the discharge of oily wastewater mixed with cleaning agents and water into the environment is complicated by the presence of iron filings and large particles of impurities on the bolt surfaces. This makes it difficult to filter the wastewater directly when it is discharged together with the cleaning agent, resulting in a cumbersome secondary filtration process and an increase in workload.

[0005] In view of this, we propose an automatic degreasing device after cold heading of bolts. Utility Model Content

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 4This application discloses an automatic degreasing device for bolts after cold heading, comprising a degreasing device body 1, a collection box 11 on the side wall of the degreasing device body 1; a plurality of casters 12 evenly fixed to the side wall of the collection box 11; a filter screen 13 on the inner side wall of the collection box 11; a drive motor 14 fixed to the side wall of the collection box 11; the output end of the drive motor 14 passes through the wall of the collection box 11 and is rotatably connected to it; a rotating rod 15 fixed to the output end of the drive motor 14; the rotating rod 15 passes through the wall of the filter screen 13 and is rotatably connected to it; a pair of scrapers 16 are symmetrically fixed to the side wall of the rotating rod 15; the side wall of the collection box 11 is provided with The device includes a vibration mechanism; a mixing mechanism on the side wall of the rotating rod 15; a pair of first magnetic blocks 17 symmetrically fixed to the side wall of the collection box 11; a pair of second magnetic blocks 18 symmetrically fixed to the side wall of the deoiling device body 1; the first magnetic blocks 17 and the second magnetic blocks 18 are magnetically connected; a drain pipe 19 is fixed to the side wall of the collection box 11; a pipe plug 110 is slidably connected to the inner side wall of the drain pipe 19; during use, by pushing the collection box 11 to below the deoiling device body 1, the caster wheel 12 rolls on the ground. At this time, the first magnetic blocks 17 and the second magnetic blocks 18 approach each other and generate an attraction, fixing the collection box 11. Then, when the deoiling device... When discharging wastewater, the main body 1 allows the wastewater to enter the collection tank 11. As the wastewater flows into the collection tank 11, it first passes through the filter screen 13, which filters out iron filings and large particles of impurities. Simultaneously, the drive motor 14 is activated, causing the rotating rod 15 to rotate. This causes the scraper 16 to scrape the surface of the filter screen 13, and the vibration mechanism pushes away the iron filings and large particles adhering to the surface of the filter screen 13, allowing the wastewater to flow normally. Furthermore, the rotation of the rotating rod 15 allows the activator in the mixing mechanism to be discharged into the collection tank 11 to mix with the wastewater. Water is mixed and purified and degraded. After a sufficient amount of wastewater is collected in the collection tank 11, the wastewater in the collection tank 11 can be discharged to the outside through the drain pipe 19 by opening the pipe plug 110. In this process, the wastewater generated after the oil removal device body 1 cleans the bolts can be filtered and purified. At the same time, it can remove iron filings and large particulate impurities mixed in the wastewater, improve the secondary utilization of wastewater, and with the cooperation of scraper 16 and vibration mechanism, the anti-clogging effect of filter screen 13 can be increased during filtration, the smoothness of wastewater flow can be improved, and thus the filtration speed can be increased.

[0025] Reference Figure 4The vibration mechanism includes springs 2; multiple springs 2 are evenly fixed between the filter screen plate 13 and the collection box 11; the filter screen plate 13, the collection box 11, and the rotating rod 15 are in sliding fit; a drive motor 21 is fixedly connected to the side wall of the collection box 11; the output end of the drive motor 21 passes through the wall of the collection box 11 and is rotatably connected to it; a striking block 22 is fixedly connected to the output end of the drive motor 21; in use, by starting the drive motor 21, the drive motor 21 can drive the striking block 22 to rotate. When the protruding side of the striking block 22 rotates to the side wall of the filter screen plate 13, it can make the filter screen plate 13 wall... When the body is struck and squeezed, the filter screen 13 can be shaken up and down under the elastic action of the spring 2. The filter screen 13 will slide on the rotating rod 15 and the wall of the collection box 11, shaking up the iron filings and large particles of impurities attached to the surface of the filter screen 13, so that the sewage can pass through quickly. In this process, the iron filings and large particles of impurities attached to the mesh of the filter screen 13 can be removed, and the filter screen 13 can be further prevented from clogging during filtration, improving the flow of sewage, reducing the accumulation of sewage on the filter screen 13, and thus increasing the filtration effect.

[0026] Reference Figure 4 and Figure 5 The mixing mechanism includes a liquid collection box 3; a pair of liquid collection boxes 3 are fixedly connected to the side wall of the rotating rod 15; the liquid collection boxes 3 are symmetrically arranged on both sides of the rotating rod 15 and have the same structure; multiple discharge ports 31 are evenly opened on the side wall of the liquid collection box 3; a pair of spring rods 32 are symmetrically fixedly connected to the inner side wall of the liquid collection box 3; a baffle 33 is fixedly connected to the end of the spring rod 32; the baffle 33 and the liquid collection box 3 are in sliding fit; in use, since the liquid collection box 3 contains a certain amount of active agent, when the rotating rod 15 rotates, the liquid collection box 3 can be rotated at the same time. At this time, under the action of centrifugal force, the baffle 33 can be thrown open, so that... When the baffle 33 presses against the spring rod 32, the active agent in the collection box 3 will be discharged into the collection tank 11 through the discharge port 31, so that it can be mixed with the sewage. When the rotating rod 15 rotates faster, the baffle 33 opens to a larger extent, the discharge port 31 leaks out a larger area, and the active agent increases accordingly. This can decompose the pollutants in the sewage. In this process, it can decompose the pollutants in the sewage, increase the purification effect of the sewage, improve the cleanliness of the sewage, and thus improve the secondary utilization effect of the sewage when it is discharged, and reduce water waste.

[0027] Reference Figure 3 and Figure 4A fixing frame 4 is fixedly connected to the side wall of the collection box 11; the fixing frame 4 has an insertion hole 41 on its side wall; a fixing plate 42 is fixedly connected to the side wall of the oil removal device body 1; the fixing plate 42 has an opening on its side wall; the insertion hole 41 and the opening are slidably connected by the same pin 43; in use, when the first magnetic block 17 and the second magnetic block 18 attract each other, the fixing frame 4 and the fixing plate 42 can be overlapped, and then the pin 43 is inserted into the opening and the side wall of the insertion hole 41 to fix the collection box 11. In this process, the fixing effect of the collection box 11 can be further increased, and the situation where the collection box 11 moves due to external force can be reduced, thereby increasing the stability of the collection box 11 in use and reducing the spillage of sewage.

[0028] Reference Figure 3 Multiple elastic pieces 5 are evenly fixed to the side wall of the pin 43; the elastic pieces 5 are arranged in an arc shape; when the pin 43 is inserted into the side wall of the opening and the insertion hole 41, the elastic pieces 5 are squeezed and will stick to the side wall of the pin 43. After the elastic pieces 5 pass through the opening and the insertion hole 41, they can automatically reset and abut against the side wall of the fixing frame 4 by utilizing the elasticity of the elastic pieces 5, thus fixing the collection box 11. In this process, the fixing effect of the pin 43 between the fixing plate 42 and the fixing frame 4 can be increased, the firmness of the pin 43 in fixing the collection box 11 can be improved, the occurrence of slippage due to external force is reduced, and thus the fixing effect of the pin 43 can be increased.

[0029] Reference Figure 2 and Figure 4 A pair of guide plates 6 are symmetrically fixed to the side wall of the collection tank 11. When the sewage flows into the collection tank 11 during use, the sewage will splash. At this time, the guide plates 6 can block the sewage. At the same time, the inclined surface of the guide plates 6 can guide the sewage into the collection tank 11. In this process, it can prevent the sewage from leaking when it enters the collection tank 11, increase the sewage collection effect, and reduce the occurrence of sewage flowing to the ground and causing difficult cleaning.

[0030] In summary, the automatic degreasing device for cold-forged bolts disclosed in this application, when in use, pushes the collection box 11 to below the degreasing device body 1, causing the caster wheel 12 to roll on the ground. At this time, the first magnetic block 17 and the second magnetic block 18 approach each other and generate an attraction, fixing the collection box 11. Then, when the degreasing device body 1 discharges wastewater, the wastewater can enter the collection box 11. When the wastewater flows into the collection box 11, it first passes through the filter screen 13, which filters out iron filings and large particles of impurities mixed in with the wastewater. At the same time, the drive motor 14 is started, which drives the rotating rod 15 to rotate, causing the scraper 16 to scrape off impurities on the surface of the filter screen 13. The vibration mechanism pushes away iron filings and large particles of impurities attached to the surface of the filter screen 13, allowing the wastewater to flow normally. When the rotating rod 15 rotates, it allows the activator in the mixing mechanism to be discharged into the collection tank 11 to mix with the wastewater for purification and degradation. After sufficient wastewater has been collected in the collection tank 11, the pipe plug 110 can be opened to discharge the wastewater to the outside through the drain pipe 19. During use, the drive motor 21 is activated, which drives the striking block 22 to rotate. When the protruding side of the striking block 22 rotates to the side wall of the filter screen 13, it strikes and squeezes the filter screen 13. At this time, under the elastic action of the spring 2, the filter screen 13... When the filter screen 13 is shaken, it slides on the wall of the collection box 11 along the rotating rod 15, shaking up iron filings and large particles of impurities attached to the surface of the filter screen 13, allowing sewage to pass through quickly. During use, because the collection box 3 contains a certain amount of active agent, when the rotating rod 15 rotates, the collection box 3 rotates simultaneously. At this time, under the action of centrifugal force, the baffle 33 is thrown open, causing the baffle 33 to squeeze against the spring rod 32. The active agent in the collection box 3 is then discharged into the collection box 11 through the discharge port 31, mixing with the sewage. The faster the rotating rod 15 rotates, the wider the baffle 33 opens, the larger the area exposed at the discharge port 31, and the more active agent is released, thus decomposing pollutants in the sewage. When in use, when the first magnetic block 17 and the second magnetic block 18 attract each other, the fixing frame 4 and the fixing plate 42 can be overlapped. Then, the pin 43 is inserted into the side wall of the opening and the insertion hole 41 to fix the collection box 11. When the pin 43 is inserted into the side wall of the opening and the insertion hole 41, the elastic piece 5 is squeezed and will stick to the side wall of the pin 43. After the elastic piece 5 passes through the opening and the insertion hole 41, it can automatically reset and abut against the side wall of the fixing frame 4 by utilizing the elasticity of the elastic piece 5, thus fixing the collection box 11. When sewage flows into the collection box 11, the sewage will splash. At this time, the guide plate 6 can block the sewage. At the same time, the inclined surface of the guide plate 6 can guide the sewage into the collection box 11.
