Description

Technical Field

[0001] This utility model relates to the technical field of electroplating equipment for workpieces in the electroplating industry, and in particular to a manual swing hanger. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. Existing related technologies involve a fixture for electroplating holes, including hooks and an electroplating rack. The electroplating rack holds the workpiece to be electroplated, which penetrates the inner hole of the workpiece. During electroplating, current is released from the cathode, and metal ions in the electroplating bath move to the workpiece surface under the influence of the potential difference to form a coating; simultaneously, the electroplating piece electroplats the inner hole wall of the workpiece. However, some workpieces have stepped inner holes. During electroplating, bubbles are generated. When these bubbles try to escape from the inner hole, they are intercepted by the steps and accumulate at the steps, resulting in poor electroplating quality for stepped inner holes. Summary of the Invention

[0003] The purpose of this invention is to provide a manual swing hanger that addresses the shortcomings of existing technologies. This hanger allows the workpiece to swing at a certain angle, making it easier to vent and drain liquid. Moreover, this swinging motion allows for more thorough contact between the workpiece surface and the solution, resulting in a more ideal electroplating effect.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a manual swing hanger, comprising a main frame, a rotating shaft, hooks, a first baffle, a second baffle, a swing linkage, a first pin, a connecting rod, and a second pin; the main frame is a welded structure, with several rotating shafts hinged to it, each rotating shaft having several hooks welded to it; the swing linkage is connected to the first baffle and the second baffle via the first pin; the lower end of the swing linkage is connected to one end of the connecting rod via the second pin, and the other end of the connecting rod is hinged to the rotating shaft.

[0005] Furthermore, the manual swing hanger described in this utility model also includes a main hook, which is installed on the top of the main frame of the hanger.

[0006] Furthermore, the hook is installed on the top of the main frame of the hanging device.

[0007] Preferably, the swing linkage of the hanger drives the workpiece hook to rotate by 90°.

[0008] The beneficial effects of this utility model are as follows: The manual swing hanger described in this utility model drives the rotating shaft to rotate through the swing linkage and connecting rod of the hanger, and then uses baffle one and baffle two to limit the rotation amplitude, which allows the workpiece to swing at a certain angle, thereby making it convenient to exhaust air and drain liquid. Moreover, this swinging method allows the workpiece surface to have more full contact with the solution, making the electroplating effect more ideal. Attached Figure Description

[0010] Figure 2 This is a side view of the present invention.

[0011] Figure 3 This is a top view of the present invention. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figures 1 to 3 As shown, the manual swing hanger of this utility model has a main frame 7, which is a welded structure. Several rotating shafts 11 are hinged to the main frame 7, and each rotating shaft 11 is welded with several hooks 8 for fixing the workpieces to be electroplated. The swing linkage 4 is connected to baffle 3 and baffle 10 via pin 1 5. Baffle 3 and baffle 10 limit the range of motion of the swing linkage 4, ensuring that the swing linkage 4 has limit positions when moving up and down. The lower end of the swing linkage 4 is connected to one end of a connecting rod 6 via pin 2 9, maintaining relative movement between the swing linkage 4 and the connecting rod 6. The other end of the connecting rod 6 is hinged to the rotating shaft 11. The main frame 7 is equipped with fifty workpiece hooks 8, allowing for simultaneous electroplating of multiple workpieces. The main frame 7 is fixedly installed inside the tank via main hooks 1 for suspending the entire hanger. A retaining ring is provided on the rotating shaft 11 for installing the retaining ring. The function of the retaining ring is to prevent the entire fixture from sliding left and right when rotating, ensuring that the workpiece completes the electroplating process safely and smoothly.

[0014] During operation, the main hook 1 is fixed inside the tank. During electroplating, the hanger swing linkage 4 needs to be manually pulled. The hanger swing linkage 4 causes the connecting rod 6, connected to the pin 9, to swing up and down. The connecting rod 6 drives the rotating shaft 11 to rotate, which in turn drives the workpiece hook 8 welded to it to rotate. When the hanger swing linkage 4 is manually pulled to its upper and lower limit positions, the angle between the two limit positions of the workpiece hook 8 is 90°. When the workpiece hook 8 swings to the left limit position, the gas inside the workpiece's inner hole is discharged; when the workpiece hook 8 swings to the right limit position, the liquid inside the workpiece's inner hole is discharged. This makes it easier to discharge liquid and gas from the workpiece's inner hole during electroplating, greatly improving the electroplating quality of the stepped inner hole of the workpiece.

[0015] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
