Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a nickel plating device for sheet metal hanging parts. Background Art

[0002] The method of plating a layer of nickel on metal or some non-metal by electrolysis is called electroplating nickel. Nickel plating is divided into electroplating nickel and chemical nickel plating. Electroplating nickel is in an electrolyte composed of nickel salt (called main salt), conductive salt, pH buffer, and wetting agent. The anode is nickel metal and the cathode is the plated object. Direct current is passed through the electrolyte to deposit a uniform and dense nickel coating on the cathode (plate). Bright nickel is obtained from the plating solution with brightener, while dark nickel is obtained from the electrolyte without brightener.

[0003] During nickel electroplating, the sheet metal hanger is immersed in an electrolyte, and a nickel plating layer is formed after power is applied. However, in the actual nickel plating process, if the hung sheet metal is in a stationary state after being immersed in the electrolyte, bubbles will be attached during the electrolysis process, causing electroplating failure. In the prior art, electroplating is completed only by moving up and down or left and right in the electrolyte, which greatly reduces the attachment of bubbles. However, its single linear movement method does not produce a large degree of electrolyte shaking, and the movement method is too limited to complete uniform electroplating.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0024] Embodiment 1:

[0025] This embodiment is used to solve the problem that during the electroplating process, the single linear movement method does not produce a large degree of electrolyte shaking, and the movement method is too limited to achieve uniform electroplating.

[0026] See also Figure 1 - Figure 6As shown, this embodiment is a nickel plating device for sheet metal hangers, including a nickel plating box 1, a hanging rail 2 is arranged above the nickel plating box 1, a plurality of partitions 3 distributed at intervals are arranged in the nickel plating box 1, and two adjacent partitions 3 form a nickel plating cavity; a cylinder 5 is slidably arranged at the bottom of the hanging rail 2, a connecting plate 6 is installed at the output end of the cylinder 5, a hanging plate 7 is hingedly arranged below the connecting plate 6, and hanging rods 11 are evenly distributed in a circular array on the outer side of the hanging plate 7; a feeding trough 8 is opened on both sides of each nickel plating cavity, and a limit rod 4 is commonly connected between the inner sides of the nickel plating box 1 corresponding to the feeding trough 8, the inner side of the hanging plate 7 is in contact with the limit rod 4, and a swing mechanism is arranged at the bottom of the connecting plate 6, and the bottom of the swing mechanism is connected to the hanging plate 7 and causes it to swing in a vertical plane;

[0027] The swing mechanism includes a rotating plate 12, an electric push rod 15, a connecting rod 16 and a connecting rod 2 17. The top of the electric push rod 15 is installed to the middle position of the inner bottom surface of the connecting plate 6. The output end of the electric push rod 15 is connected to a lifting rod 18. The two ends of the lifting rod 18 are rotatably connected with one end of the connecting rod 16 or the connecting rod 2 17.

[0028] The rotating plate 12 is arranged on both sides of the bottom of the connecting plate 6, and a rotating rod 13 is rotatably installed at the bottom of the rotating plate 12. A plurality of hangers 14 are connected to the middle of the rotating rod 13. The bottom of the hanger 14 is connected to the top of the hanging plate 7, and the other ends of the connecting rod 16 and the connecting rod 2 17 are fixedly connected to the hanger 14 on the outside.

[0029] The cylinders 5 are arranged at intervals, and a moving block 9 is installed on the top of the cylinder 5. The moving block 9 is slidably connected to the hanging rail 2. The rail groove on the hanging rail 2 is aligned with the middle of the nickel plating box 1 and is elliptical. A circular immersion net 10 is arranged in the middle of the hanging plate 7. The hanging rod 11 is evenly arranged on the immersion net 10, and the outer end of the hanging rod 11 is arc-shaped and bent upward;

[0030] See also Figure 1-Figure 6 As shown, before the nickel plating process, the sheet metal hangers to be electroplated are first hung one by one through the hanging rods 11 to ensure that no collision occurs, and then the number of moving blocks 9 and the number of bottom hanging plates 7 are determined according to the number of nickel plating cavities to perform the nickel plating process;

[0031] During the processing: when each group of hanging plates 7 moves to just above the nickel plating chamber, the cylinder 5 is started, and the cylinder 5 drives the connecting plate 6 to move vertically downward, and the electric push rod 15 is started synchronously. The telescopic end of the electric push rod 15 extends downward to drive the connecting rod 16 and the connecting rod 2 17 to expand, and the hanging plate 7 is expanded outward to the outside of the limit rod 4; the telescopic end of the cylinder 5 continues to move downward, and the inner side of the hanging plate 7 contacts the limit rod 4 at this time, and then the cylinder 5 continues to drive the hanging plate 7 to move downward. The hanging plate 7 is blocked by the limit rod 4, and the expansion angle during the vertical downward displacement process will gradually increase until the bottom of the hanging plate 7 contacts the bottom of the nickel plating box 1 and stops; at this time, the cylinder 5 contracts, driving the hanging plate 7 to move upward, and together with the above-mentioned descending and outward expanding action, a "swinging" action is formed, thereby ensuring that the sheet metal hangers on the hanging plate 7 avoid the adhesion of bubbles and form uniform electroplating.

[0032] Embodiment 2:

[0033] This embodiment is based on the first embodiment. When the limit rod 4 is not provided on the nickel plating box 1, the swing effect is achieved by combining the swing mechanism with the cylinder 5 to complete uniform electroplating.

[0034] See also Figure 5 As shown, a nickel plating device for sheet metal hangers of this embodiment includes that when the telescopic end of the cylinder 5 is extended, the inner side of the hanging plate 7 contacts the limit rod 4 and moves downward and gradually expands outward;

[0035] When there is no limit rod 4, refer to Figure 5 As shown, the details are as follows: the cylinder 5 is started to drive the hanging plate 7 as a whole to be immersed downward in the electrolyte, and the electric push rod 15 is turned on. The electric push rod 15 is continuously extended and contracted in a cycle to drive the hanging plate 7 as a whole to swing in the electrolyte. The difference between it and the first embodiment is that the limit rod 4 is not provided, and the swinging action is completed by driving the electric push rod 15, which can increase the swing amplitude of the hanging plate 7 in the electrolyte, thereby achieving the purpose of achieving uniform electroplating of the sheet metal hanging parts on the hanging plate 7;

[0036] It should be noted that the material of the telescopic end of the electric push rod 15 is an insulating material. During the extension of the electric push rod 15, even if the telescopic end of the electric push rod 15 drives the lifting rod 18 to be immersed in water, it can prevent the electric push rod 15 from being damaged due to conduction.

[0037] Combining Example 1 and Example 2, the fixed telescopic structure can be used to realize the swing of the sheet metal hanger on the vertical plane, so as to avoid the adhesion of bubbles to the sheet metal hanger during the electroplating process, and the telescopic structure can be used together with the telescopic connecting rod structure to realize the comprehensive swing of the sheet metal hanger, thereby increasing the swing amplitude and enhancing the uniformity of electroplating.
