Description

Technical Field

[0001] The utility model relates to the technical field of pickling and phosphating, in particular to a pickling and phosphating device for metal parts. Background Technique

[0002] Pickling and phosphating can remove the oxide layer and impurities on the metal surface. Metals will react with oxygen when exposed to air for a long time, forming an oxide layer. This oxide layer not only affects the appearance of the metal surface but also reduces the corrosion resistance of the metal. The acid in pickling and phosphating can effectively dissolve the oxide layer, making the metal surface smooth again and removing impurities to ensure the quality of subsequent processing.

[0003] When some existing pickling and phosphating devices carry out pickling and phosphating on metal parts, first, the metal parts are pickled to remove impurities and oxide layers and other substances on the surface of the metal parts. Then, the metal parts are immersed in a solution containing phosphoric acid substances, so that a phosphating layer is formed on the surface of the metal parts. During the process of using phosphating solution to phosphating metal parts, some debris is likely to fall off the surface of the metal parts. The traditional slag removal method is to use the method of regular tank turning and sedimentation slag removal. Since some existing pickling and phosphating devices do not install a debris cleaning structure, this will affect the repeated use of the phosphating solution. If the method of regular tank turning and sedimentation slag removal is used, it needs to stop production for a long time, which takes a long time and causes great waste.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. The metal parts pickling and phosphating equipment allows the phosphating solution to continuously enter the interior of the filter tank through the water inlet tank. Due to the effect of the baffle, the one-way plate cannot be opened in reverse, so that the phosphating solution entering the interior of the filter tank can only be discharged through the filter tank, so the debris cannot leave the interior of the slag storage tank through non-human means. When the phosphating solution passes through the interior of the filter tank, the metal debris in the phosphating solution will be isolated by the filter plate, and thus remain in the interior of the slag storage tank. The phosphating solution will be discharged again through the filter tank, and the debris cleaning process is achieved, thereby reducing the problem of affecting the repeated use of the phosphating solution. The staff only needs to regularly remove the slag storage plate from the interior of the filter tank to clean the debris inside the slag storage tank and the debris on the surface of the filter plate, so that part of the debris in the phosphating solution can be cleaned and collected without stopping the equipment, so that the impact of repeated use of the phosphating solution is reduced, a large amount of debris removal time is saved, and the work efficiency is increased while reducing the waste of the phosphating solution.

[0012] 2. The metal parts pickling and phosphating equipment, when in use, the staff rotates the worm to make the worm drive the worm wheel to rotate, thereby rotating the threaded rod. When the threaded rod rotates, the threaded rod will drive the two sliding plates to move relative to each other through the two reverse threads on its surface, and the sliding plate will drive the sealing plate and the second sealing plate to move relative to each other, and the sealing slide will slide inside the sealing slide groove. When the sealing plate meets the opposite side of the second sealing plate, the closure of the liquid storage tank is completed. At this time, the sealing strip will slide into the inside of the sealing groove. At this time, the inside of the liquid storage tank is in a sealed state. At this time, the staff turns on the electricity to make the electric drive center rotate, and at the same time, the heating is turned on for heating. The electric heating plate can heat the phosphating solution, which is convenient for accelerating the phosphating speed and reducing the probability of air entering the liquid storage tank and affecting the phosphating effect on metal parts.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-10 , the present invention provides a technical solution: a pickling and phosphating equipment for metal parts, including an equipment body 1. A top cover 2 is fixedly installed on the upper surface of the equipment body 1. The shape of the top cover 2 is in a U shape. A liquid storage tank 23 is opened at the top of the equipment body 1. The lower surface of the equipment body 1 is fixedly connected to a motor 19. The motor 19 is an existing device and will not be elaborated here. The output end of the motor 19 rotates through the lower surface of the equipment body 1 and extends into the interior of the liquid storage tank 23. The output end of the motor 19 is fixedly connected to a central axis 3. A heating plate 5 is fixedly installed at the bottom of the liquid storage tank 23. The heating plate 5 can heat the phosphating solution to make the phosphating effect better. The heating plate 5 is an existing device and will not be elaborated here. The heating plate 5 is rotationally sleeved on the surface of the central axis 3. A stirring plate 4 is fixedly connected to the surface of the central axis 3. One side of the stirring plate 4 away from the central axis 3 is slidably connected to the inner wall of the liquid storage tank 23. A collection plate 25 is fixedly connected to the inner wall of the liquid storage tank 23. Two symmetric sealing plate chutes 12 are opened inside the top cover 2. A sealing plate 7 is slidably connected inside the left sealing plate chute 12, and a second sealing plate 24 is slidably connected inside the right sealing plate chute 12. A driving groove 13 communicating with the inside of the sealing plate chute 12 is opened inside the top cover 2. A filter tank 11 is opened on one side of the collection plate 25. The shape of the filter tank 11 is in a T shape. A debris filtering device is arranged inside the filter tank 11.

[0026] Furthermore, the debris filtering device includes a slag storage plate 6, the surface of which is slidably connected to the inside of the filter tank 11, and a water inlet tank 10 connected to the inside of the filter tank 11 is opened on the other side of the collecting plate 25. A one-way plate 26 is rotatably connected to the inside of the water inlet tank 10, and a baffle 27 is fixedly connected to the bottom of the water inlet tank 10. The baffle 27 is a limit plate of the one-way plate 26, so that the one-way plate 26 can only rotate toward the inside of the filter tank 11. A slag storage tank 8 connected to the other side of the slag storage plate 6 is opened on one side of the slag storage plate 6, and a filter plate 9 is fixedly installed inside the slag storage tank 8.

[0027] When the central shaft 3 rotates, the central shaft 3 will drive the stirring plate 4 to rotate synchronously. When the stirring plate 4 rotates, the metal parts in the phosphating solution will be stirred to move, which can accelerate the formation of the phosphating film. During the phosphating process, since the stirring plate 4 is constantly rotating inside the liquid storage tank 23, the phosphating solution will continuously squeeze the one-way plate 26, so that the one-way plate 26 opens toward the inside of the filter tank 11, so that the phosphating solution continuously enters the inside of the filter tank 11 through the water inlet tank 10. Due to the effect of the baffle 27, the one-way plate 26 cannot be opened in the reverse direction, thereby entering The phosphating liquid inside the filter tank 11 can only be discharged through the filter tank 11, so the debris cannot leave the inside of the slag storage tank 8 by unintentional means. When the phosphating liquid passes through the filter tank 11, the metal debris in the phosphating liquid will be isolated by the filter plate 9 and remain in the slag storage tank 8. The phosphating liquid will be discharged again through the filter tank 11 to achieve the debris cleaning process, thereby reducing the problems that affect the repeated use of the phosphating liquid. The staff only needs to regularly remove the slag storage plate 6 from the filter tank 11 to clean the debris inside the slag storage tank 8 and the debris on the surface of the filter plate 9.

[0028] Furthermore, two sealing slides 14 are fixedly connected to the lower surfaces of the sealing plate 7 and the second sealing plate 24, and two sealing slide grooves 21 are provided on the upper surface of the equipment body 1. The surface of the sealing slide 14 is slidably connected to the inside of the sealing slide groove 21. When the sealing plate 7 and the second sealing plate 24 are closed, the sealing slide 14 and the sealing slide groove 21 play a sealing role.

[0029] Furthermore, the interior of the driving groove 13 is rotatably connected to a threaded rod 17, and a worm wheel 15 is fixedly sleeved on the surface of the threaded rod 17. The surface of the threaded rod 17 is provided with two sections of reverse threads starting from the two sides of the worm wheel 15. The rear side of the top cover 2 is rotatably connected to a worm 16 extending to the interior of the driving groove 13. The surface of the worm 16 is meshed with the surface of the worm wheel 15. When the worm 16 rotates, the threaded rod 17 will rotate.

[0030] Furthermore, a sliding plate 18 is fixedly connected to one side of the sealing plate 7 and the second sealing plate 24 close to the driving groove 13 , and a surface of the sliding plate 18 is slidably connected to the inside of the threaded rod 17 .

[0031] Furthermore, the sliding plate 18 is threadedly sleeved on the surface of the threaded rod 17. When the threaded rod 17 rotates, the threaded rod 17 will drive the two sliding plates 18 to move relative to each other through the two reverse threads on its surface. The sliding plate 18 will drive the sealing plate 7 and the second sealing plate 24 to move relative to each other. When the opposite sides of the sealing plate 7 and the second sealing plate 24 meet, the liquid storage tank 23 is closed.

[0032] Furthermore, a sealing strip 20 is fixedly connected to one side of the sealing plate 7 close to the second sealing plate 24 , and the sealing strip 20 is in a U-shape. A sealing groove 22 is provided on one side of the second sealing plate 24 close to the sealing plate 7 , and the sealing groove 22 is in a U-shape.

[0033] Furthermore, the surface of the sealing strip 20 is slidably connected to the interior of the sealing groove 22 .

[0034] When the sealing plate 7 and the second sealing plate 24 close the liquid storage tank 23 , the sealing strip 20 will slide into the sealing groove 22 , and the sealing strip 20 and the sealing groove 22 will play a sealing role.

[0035] Working principle: When using the metal parts pickling and phosphating equipment, the metal parts are placed in the liquid storage tank 23 so that the metal parts are completely in the phosphating solution. At this time, the staff rotates the worm 16, so that the worm 16 drives the worm wheel 15 to rotate, thereby rotating the threaded rod 17. When the threaded rod 17 rotates, the threaded rod 17 drives the two sliding plates 18 to move relative to each other through the two reverse threads on its surface. The sliding plate 18 drives the sealing plate 7 and the second sealing plate 24 to move relative to each other, and the sealing slide 14 moves in the sealing The sealing groove 21 slides inside. When the sealing plate 7 meets the opposite side of the second sealing plate 24, the liquid storage tank 23 is closed. At this time, the sealing strip 20 slides into the inside of the sealing groove 22. At this time, the inside of the liquid storage tank 23 is in a sealed state, reducing the probability of air entering the inside of the liquid storage tank 23 and affecting the phosphating effect of the metal parts. At this time, the staff turns on the motor 19 to make the motor 19 drive the central shaft 3 to rotate, and at the same time, the heating plate 5 is powered on for heating. When the central shaft 3 rotates, the central shaft 3 drives the stirring plate 4 to rotate. When the stirring plate 4 rotates, the metal parts in the phosphating solution are stirred to move, which can accelerate the formation of the phosphating film. During the phosphating process, since the stirring plate 4 is constantly rotating inside the liquid storage tank 23, the phosphating solution will continuously squeeze the one-way plate 26, so that the one-way plate 26 opens toward the inside of the filter tank 11, so that the phosphating solution continuously enters the inside of the filter tank 11 through the water inlet tank 10. Due to the effect of the baffle 27, the one-way plate 26 cannot be opened in the reverse direction, so that the phosphating solution entering the filter tank 11 can only be discharged through the filter tank 11. Out, so the debris cannot leave the interior of the slag storage tank 8 by non-human means. When the phosphating solution passes through the filter tank 11, the metal debris in the phosphating solution will be isolated by the filter plate 9 and remain in the slag storage tank 8. The phosphating solution will be discharged again through the filter tank 11, and the debris cleaning process will be achieved, thereby reducing the problem of affecting the repeated use of the phosphating solution. The staff only needs to regularly remove the slag storage plate 6 from the filter tank 11 to clean the debris inside the slag storage tank 8 and the debris on the surface of the filter plate 9, thereby reducing the problem of affecting the repeated use of the phosphating solution.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
