Description

Technical Field

[0001] This utility model relates to the field of impeller processing technology, specifically to an electroplating device for impeller processing. Background Technology

[0002] An impeller refers both to the disk containing moving blades, a component of the rotor of an impulse steam turbine, and to the entire disk and the rotating blades mounted on it. Impellers can be classified according to their shape and opening / closing status. In impeller manufacturing, electroplating involves depositing metal onto the surface of a conductive object through electrolysis. Electroplating typically involves immersing the object to be plated as the cathode or anode in an electrolyte containing metal ions. An applied voltage causes the metal ions to deposit on the object's surface, forming a metal coating. During this process, metal ions in the electrolyte are reduced to the object's surface due to the influence of the electric current, forming a metal deposit. The existing technology has the following problems:

[0003] The impeller is immersed in the electrolyte. However, due to the different shapes of the impeller blades, its surface is uneven. Therefore, it is difficult to ensure the uniformity of the coating during the electroplating process. There may be local insufficient or excessive coating, which will affect the overall electroplating effect of the impeller. Secondly, after the impeller is electroplated and then washed with water, the water on the impeller surface is usually air-dried, which is inefficient. Utility Model Content

A drain pipe is fixedly connected to the bottom of the front end of the electroplating tank, and a valve is provided on the outer wall of the drain pipe. A control panel is provided on the upper side of the front end of the electroplating tank.

[0007] A further improvement of the present invention is that the stirring mechanism includes a mounting sleeve, a rotary motor, a rotating rod, and a spiral blade.

The inner walls of the several threaded tubes are threadedly connected to the outer wall of the transverse surface of the mounting rod. The inner wall of the knob is fixedly connected to one side of the outer wall of the threaded tube.

[0010] A further improvement of this utility model is that the top of the mounting rod in the vertical direction is fixedly connected to the left side of the bottom of the top plate.

[0011] A further improvement of this utility model is that: several air outlets that run vertically through each other are respectively opened on the front and rear sides of the top plate near the mounting rod, and the inner walls of the several air outlets are rotatably connected with guide vanes.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides an electroplating device for impeller processing. It employs a combination of an electroplating tank, a top plate, a hydraulic cylinder, a telescopic support rod, a fixed plate, a stirring mechanism, and a suspension assembly. Multiple impellers are sequentially positioned on the suspension assembly through a central connection hole. The hydraulic cylinder then moves the top plate downwards, immersing the impellers in the electrolyte. The stirring mechanism agitates the electrolyte, increasing its flow rate. This solves the problem of uneven impeller surfaces due to varying blade shapes, which makes it difficult to ensure uniform plating during electroplating. This can result in insufficient or excessive plating in certain areas, affecting the overall electroplating effect. The device achieves a more uniform plating thickness and improves the overall electroplating effect of the impeller.

[0016] 2. This utility model provides an electroplating device for impeller processing, which uses a combination of a top plate, a heating box, a fan, and a heating mechanism. After the impeller is cleaned to remove excess electrolyte from its surface, the fan and heating mechanism are operated. The fan converts the heat generated by the heating mechanism into hot air and blows it onto the surface of the impeller, thereby quickly drying the moisture on the impeller surface. This solves the problem of low efficiency in drying the moisture on the impeller surface after water washing following electroplating, and achieves the beneficial effect of improving the drying efficiency of the impeller surface.

Connecting plates 3 are fixedly connected to the left and right ends of the outer wall of the electroplating tank 1, a hydraulic cylinder 4 is fixedly connected to the top of the right connecting plate 3, a telescopic support rod 5 is fixedly connected to the top of the left connecting plate 3, and fixing plates 6 are fixedly connected to the left and right ends of the top plate 2. The output ends of the connecting plates 3 and the top plate 2 are fixedly connected to the bottom of the two fixing plates 6, a stirring mechanism 7 is provided on the lower side inside the electroplating tank 1, a suspension assembly 8 is provided on the middle side of the bottom of the top plate 2, a heating box 9 is fixedly connected to the top of the top plate 2, a fan 10 is fixedly connected to the left and right sides of the top of the heating box 9, a heating mechanism 11 is provided on the left end of the heating box 9, and the outside of the heating mechanism 11 extends into the inside of the heating box 9. A drain pipe 12 is fixedly connected to the bottom of the front end of the electroplating tank 1, a valve 13 is provided on the outer wall of the drain pipe 12, and a control panel 14 is provided on the upper side of the front end of the electroplating tank 1.

[0025] The system consists of an electroplating tank 1, a top plate 2, a hydraulic cylinder 4, a telescopic support rod 5, a stirring mechanism 7, a suspension assembly 8, a heating box 9, a fan 10, and a heating mechanism 11. Multiple impellers are sequentially positioned using the suspension assembly 8. The hydraulic cylinder 4 and the telescopic support rod 5 control the lifting and lowering movement of the top plate 2, immersing the impellers in the electroplating tank 1 for electroplating. The stirring mechanism 7 ensures a more uniform plating thickness, improving the overall electroplating effect of the impellers. After electroplating, the fan 10 and the heating mechanism 11 work together to quickly dry the surface moisture of the impellers.

[0026] like Figure 2As shown, this utility model provides a technical solution for an electroplating device for impeller processing: the stirring mechanism 7 includes a mounting sleeve 71, a rotary motor 72, a rotating rod 73, and a spiral blade 74. The outside of the rotary motor 72 is disposed inside the mounting sleeve 71. The output shaft of the rotary motor 72 is fixedly connected to one end of the rotating rod 73. The other end of the rotating rod 73 passes through the inside of the mounting sleeve 71 and is rotatably connected to the inner wall of the electroplating tank 1. The inner wall of the spiral blade 74 is fixedly connected to the outer wall of the rotating rod 73. One end of the mounting sleeve 71 is fixedly connected to the inner wall of the electroplating tank 1. The rotary motor 72 drives the rotating rod 73 to rotate, so that the spiral blade 74 tumbles and stirs the electrolyte in the electroplating tank 1, promoting the flow rate of the electrolyte. A partition filter plate 101 is fixedly connected to the upper side of the inner wall of the electroplating tank 1 near the stirring mechanism 7. The partition filter plate 101 serves to separate the impeller from the stirring mechanism 7.

[0027] like Figure 3 As shown, this utility model provides a technical solution for an electroplating device for impeller processing: the suspension assembly 8 includes a mounting rod 81, several threaded fixed tubes 82, and several knobs 83. The mounting rod 81 is L-shaped, and the outer wall of the horizontal surface of the mounting rod 81 is provided with a threaded groove 810. The inner walls of the several threaded fixed tubes 82 are threadedly connected to the outer wall of the horizontal surface of the mounting rod 81. The inner wall of the knob 83 is fixedly connected to one side of the outer wall of the threaded fixed tube 82. The impeller is sleeved on the mounting rod 81, and the threaded fixed tubes 82 are screwed and moved on the mounting rod 81 by the knobs 83, which serves to clamp and position the two ends of the impeller surface. The top of the mounting rod 81 in the vertical direction is fixedly connected to the left side of the bottom of the top plate 2.

[0028] like Figure 4 As shown, this utility model provides a technical solution for an electroplating device for impeller processing: the top plate 2 has several vertically penetrating air outlets 201 on the front and rear sides near the mounting rod 81, and the inner walls of the several air outlets 201 are rotatably connected with guide vanes 21. The guide vanes 21 are installed in the air outlets 201, and the direction of the air blown out of the air outlets 201 can be adjusted by rotating the guide vanes 21.

[0029] like Figure 5As shown, this utility model provides a technical solution for an electroplating device for impeller processing: the heating mechanism 11 includes a temperature controller 111, a plurality of heating rods 112 and a plurality of heat sinks 113. The ends of the plurality of heating rods 112 are equidistantly arrayed and electrically connected to one end of the temperature controller 111. The outer walls of the plurality of heating rods 112 are all disposed inside the heating chamber 9. The outer walls of the heating rods 112 are wound and connected to the inner walls of the heat sinks 113. The heat sinks 113 are provided to increase the heat dissipation area and efficiency, which not only improves the heat dissipation performance of the heating rods, but also ensures that the heat is distributed and transferred more evenly. The outer wall of the temperature controller 111 is fixedly connected to the left end of the outer wall of the heating chamber 9. The fan 10 and the interior of the heating chamber 9 are interconnected.

[0030] The working principle of this electroplating device for impeller processing will be explained in detail below.

[0031] like Figure 1-5 As shown, during the impeller processing, when electroplating the impeller after grinding and degreasing, firstly, the device is connected to an external power source via a wire. The impeller is then inserted into the mounting rod 81 through the connection port. Next, the threaded guide tube 82 is rotated via the knob 83, causing it to move along the outer wall of the mounting rod 81, moving it to the impeller surface for positioning and clamping at both ends. Multiple impellers are then sequentially suspended on the mounting rod 81 using the same steps. Then, the control panel 14 activates the hydraulic cylinder 4. The output end of the hydraulic cylinder 4, along with the telescopic support rod 5, moves the top plate 2 downwards, immersing the suspended impellers in the electrolyte in the electroplating tank 1. The control panel 14 then activates the rotary motor 72, whose output shaft drives... Rotating the rotating rod 73 causes the spiral blades 74 to agitate the electrolyte, making it tumble and increase its flow rate. This results in a more uniform plating thickness and improves the overall plating effect of the impeller. After plating, the electrolyte in the plating tank 1 is discharged through the drain pipe 12 by opening the valve 13. Clean water is then injected into the plating tank 1 to clean the impeller and remove excess electrolyte from its surface. The hydraulic cylinder 4 is then operated to lift the top plate 2 from the plating tank 1. The temperature controller 111 is used to adjust the temperature of the heating rod 112. The air guide vane 21 in the air outlet 201 is then rotated to adjust the airflow direction. Combined with the fan 10, the heat generated by the heating mechanism 11 is converted into hot air and blown onto the surface of the impeller, thereby quickly drying the moisture on the impeller surface.

[0032] The specific types and structures of the hydraulic cylinder 4, rotary motor 72, fan 10, temperature controller 111, heating rod 112 and valve 13 used are all existing products. The specific circuit connection structure and control relationship between the control panel 14 and the hydraulic cylinder 4, rotary motor 72, fan 10, temperature controller 111 and heating rod 112 are also existing technologies, and will not be described in detail here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
