Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electroplating processing, in particular to an oxidizing mechanism for blind hole parts. BACKGROUND

[0002] In an industrial production process, in order to improve the corrosion resistance, wear resistance and appearance of mechanical parts, forming a dense artificial oxide layer on the surface of aluminum materials has become one of the commonly used methods, but when it comes to components with closed end face characteristics, namely so-called "blind hole", challenges are faced because the traditional method is difficult to ensure that the solution uniformly penetrates into the deep and narrow space to complete the reaction, resulting in the possibility that the local area is not fully oxidized or cannot contact the electrolyte at all and fails, and how to improve the plating efficiency under this specific condition has become a hot spot in the research of existing processing technology.

[0003] According to the deep blind hole part oxidation electroplating hanger disclosed in Chinese Patent Publication No. CN220907712U, the part can be inclined and swung in the forward and reverse directions, the openings of the deep blind holes of the part can be alternately directed upward to discharge the gas (including air) in the holes, the liquid medicine can fully contact the hole walls of the part to generate a surface treatment electroplated layer or an oxidation layer, and the mutual exchange of the liquid medicine in the holes and the liquid medicine outside the holes can be promoted to improve the production efficiency of the high-plated layer or the oxidation layer on the hole wall surface, so that more comprehensive electroplating effect can be achieved.

[0004] However, the patent still has some shortcomings in actual use. In the process of electroplating oxidation, not only the use of the hanger is needed, but also the cooperation of the electroplating tank is needed. After the part is soaked in the liquid medicine, the gas in the blind hole can be discharged through the swinging mode, but it cannot be known whether the gas in the blind hole is completely discharged during the opening upward process. If the residence time of the opening upward is not enough, there will still be some gas remaining in the blind hole, which will cause the actual electroplating effect to have some room for improvement. In view of this, the application provides an oxidation mechanism for blind hole parts to solve the above problems based on the cooperation of the hanger and the electroplating tank.

[0037] It should be noted that the left side of the fixed block 402 is provided with a through hole for the transmission rod 509 to penetrate, so that the transmission rod 509 can normally move, the hanger body 505 can be a clamping structure cooperated by a bolt and a clamping plate, and is a common hanger positioning structure in existing industrial processing technology, so no more description is given.

[0038] In addition, the front and back linkage rods 511 are symmetrically distributed front and back, the front and back of each circular ring block 506 is fixed with two symmetrical plates 507, the opposite sides of the corresponding two symmetrical plates 507 are hingedly connected through a pin shaft and the outer side of the corresponding linkage rod 511, and the top of the connecting plate 501 is provided with two movable holes for the four linkage rods 511 to penetrate respectively, so that the linkage rod 511 can drive the corresponding symmetrical plate 507 to rise or fall under the action of hinging, and then drive the rotating rod 503 to rotate synchronously, so as to realize the effect of alternating swing.

[0039] Meanwhile, the outer side of the driving bevel gear 513 and the outer side of the driven bevel gear 514 are engaged with each other, so that the driving bevel gear 513 can drive the driven bevel gear 514 to rotate, and the vertical lifting mechanism 2 comprises a lifting box, a supporting shaft, a chain wheel, a chain, a synchronous belt, a synchronous wheel and a motor, specifically, the corresponding supporting shaft is driven to rotate by the motor, and the two supporting shafts at the top are both opened to rotate under the action of the synchronous wheel and the synchronous belt, then the supporting shaft at the bottom is also opened to rotate under the cooperation of the chain wheel and the chain, and the chain is supported by the chain wheel, so that the fixed rod 401 is driven to move up and down, and then the lifting or lowering of the swing assembly 500 is realized, wherein the fixed rod 401 is fixed between the two chains on the opposite side, and the opposite side of the two lifting boxes is opened, so that the fixed rod 401 can normally move up and down, and the vertical lifting technology is the existing public technology, so it is not described in detail.

[0040] In addition, the nozzle 307 is arranged towards the side close to the hanger frame 502, and the stirring blade 302 is located below the hanger frame 502, so that the liquid medicine sprayed by the nozzle 307 and the liquid medicine flowing under the driving of the stirring blade 302 can move towards the side close to the part, and the flowability of the liquid medicine can be improved to improve the effect of electroplating.

[0041] The working principle of the above embodiment is as follows:

[0042] In the electroplating process of industrial parts, after positioning the parts on the hanger body 505, start the vertical lifting mechanism 2, drive the connecting plate 501 into the inside of the electroplating tank 1 at a uniform and slow speed through the fixed rod 401 and the fixed block 402, and let the parts soak in the liquid medicine. At this time, the air in part of the blind hole will be discharged. Start the second servo motor 512, drive the transmission rod 509 to rotate through the cooperation between the driving bevel gear 513 and the driven bevel gear 514, so that the disc 510 can rotate, and then drive the linkage rod 511 to move, so that each symmetrical plate 507 can be lifted or lowered, and then the circular ring block 506 drives the corresponding rotating rod 503 to rotate to the front side or the back side, to meet the swinging needs of the parts, so that both sides of the parts can be driven and stayed on the side facing the top, so that the air in the inside can be discharged. Even if the air in the blind hole has not been effectively discharged in the previous discharge action, the air in the inside can continue to be discharged when moving to the side facing the top, realizing continuous exhaust during electroplating, so that the liquid medicine can enter the inside of the blind hole as much as possible. Start the water pump 306 to pump the liquid medicine at the bottom of the electroplating tank 1 into the inside of the main pipeline 304, and then into the inside of each vertical pipe 303, and finally sprayed out through the nozzle 307, so that the liquid medicine can flow to the side close to the parts, and under the action of the impact force, the efficiency of the liquid medicine entering the inside of the blind hole can be further increased, so as to improve the overall electroplating effect. Start the first servo motor 301 to drive the stirring blade 302 to rotate, so that the liquid medicine at the bottom of the electroplating tank 1 can be upwardly conveyed to avoid accumulation on the bottom, and also increase the flowability of the liquid medicine, so as to further improve the electroplating efficiency and effect, so that the parts and the blind hole inside the parts can be fully and effectively electroplated.

[0043] Compared with the prior art, the blind hole part oxidation mechanism can further improve the overall electroplating effect of the parts through the cooperation between the electroplating tank 1, the vertical lifting mechanism 2, the auxiliary electroplating assembly 300 and the swinging assembly 500. The parts soaked in the liquid medicine are continuously and stably swung, so that the air in the blind hole can be discharged as much as possible. At the same time, through the targeted injection pipeline, the liquid medicine can be continuously conveyed to the outside of the parts, and the flowability of the liquid medicine is improved, so that the molecules can move quickly, and better plating film effect can be achieved in a certain time, thereby effectively improving the actual electroplating effect, and effectively improving the practicality of the blind hole part oxidation mechanism, solving the problem of insufficient comprehensive electroplating effect in the actual operation process of the existing deep blind hole part oxidation electroplating process.
