Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating processing technology, specifically a convenient operating device for a U-shaped dovetail electroplating hanger. Background Technology
[0002] Plastic electroplating technology, by combining a metal layer with a plastic substrate, exhibits significant advantages in the industrial field. It imparts a metallic luster and tactile feel to plastic products, compensating for the inherent cheapness of plastic and significantly enhancing their decorative value. It can achieve diverse surface effects (such as imitation chrome and gold), meeting the high-end appearance demands of electronic products and automotive interiors. Plastic electroplating fixtures, as key auxiliary tools in the electroplating process, must be designed to balance functionality, corrosion resistance, and cost-effectiveness. General electroplating fixtures often exhibit poor clamping stability during electroplating. Plastic electroplating racks frequently experience unstable conductivity at the clamping points. Uneven stress on the product on the rack can lead to current breakdown or deformation at the clamping points, severely impacting the post-electroplating quality. The main reason for this is the lack of effective measures to increase conductivity in the design of the electroplating rack contacts, preventing continuous conductivity. Simultaneously, uneven stress on the plastic parts at the rack contacts causes product deformation. Utility Model Content

[0014] Compared with the prior art, this utility model provides a convenient operating device for a U-shaped dovetail electroplating hanger, which has the following advantages:
[0015] 1. This U-shaped dovetail electroplating fixture features a convenient operating device. It supports plastic parts through the cooperation of two sets of horizontal support ends, vertical blocking ends, and anti-detachment limiting ends. Then, the flattened clamping part and the dovetail joints cooperate to clamp the plastic parts that are stuck inside the horizontal support ends, vertical blocking ends, and anti-detachment limiting ends, which improves the stability of clamping. Furthermore, the cooperation of the upper and lower ends in clamping further enhances the stability of support and prevents product deformation.

[0017] 3. This U-shaped dovetail electroplating fixture features a convenient operating device. When ready to clamp, simply move the connecting synchronous frame to bend the clamping frame to the left. The clamping frame then moves the dovetail clamp to the left, allowing the plastic part to be inserted into the U-shaped frame. Afterward, release the connecting synchronous frame, and the clamping frame returns to its original shape, moving the dovetail clamp into the U-shaped frame to quickly clamp and fix the plastic part. The operation is simple and easy to use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 This utility model provides a convenient operating device for a U-shaped dovetail electroplating hanger, including a support frame 1 for suspending and supporting electroplated products and a clamping frame 3 for clamping and fixing electroplated products. The end of the support frame 1 is bent to form a U-shaped frame 2 to improve suspension stability, and the end of the clamping frame 3 is provided with a dovetail clip 4 to improve clamping stability.
[0024] Furthermore, the tail end of the support frame 1 is fixedly installed on the surface of the main frame 5, and the tail end of the clamping frame 3 is fixedly installed on the surface of the main frame 5. A secondary support 6 is installed on the front side wall of the main frame 5. The secondary support 6 supports the middle part of the support frame 1. The contact position between the secondary support 6 and the support frame 1 is fixedly welded. The main frame 5 supports the support frame 1 and the clamping frame 3, and the secondary support 6 supports the middle part of the support frame 1, thereby improving the stability of the support.
[0025] Furthermore, the U-shaped frame 2 includes a horizontal support end 21, a vertical blocking end 22, and an anti-slip limiting end 23. The horizontal support end 21 is located at the end of the support frame 1, and the vertical blocking end 22 is vertically located at the right end of the horizontal support end 21. The anti-slip limiting end 23 is fixedly connected to the top of the vertical blocking end 22. The plastic part is supported by the horizontal support end 21, and then, during the subsequent clamping process, the plastic part is blocked and clamped by the vertical blocking end 22. The anti-slip limiting end 23 blocks the top of the vertical blocking end 22 to prevent the plastic part from slipping off from above, thereby improving the stability of the clamping.
[0026] Furthermore, the dovetail clip 4 includes a flattening clamping part 41 and a dovetail contact 42. The flattening clamping part 41 is located at the end of the clamping frame 3, and the dovetail contact 42 is located at the end of the flattening clamping part 41 away from the clamping frame 3. The plastic parts that are stuck inside the U-shaped frame 2 are pressed and fixed by the cooperation of the flattening clamping part 41 and the dovetail contact 42.
[0027] Furthermore, the clamping frames 3 are arranged in pairs, and the two clamping frames 3 are longitudinally connected by a connecting synchronous frame 7. By moving the connecting synchronous frame 7, the upper and lower clamping frames 3 can be controlled simultaneously for clamping, which is convenient for control.
[0028] Furthermore, the surfaces of the support frame 1, U-shaped frame 2, auxiliary support 6, and connecting synchronous frame 7 are all covered with an insulating layer, so that after power is applied, the current can flow fully through the U-shaped frame 2 and dovetail clip 4 into the plastic parts, improving the power conduction effect of the plastic parts and reducing leakage.
[0029] Furthermore, the U-shaped frame 2 is made by bending stainless steel wire with a diameter of 3.0mm. The vertical blocking end 22 is flattened and roughened. The maximum diameter of the vertical blocking end 22 is 3.2mm. The flattening and roughening treatment increases the effective contact area with the workpiece by adjusting the flatness of the clamp contact surface, reducing workpiece deformation or slippage caused by excessive local pressure, ensuring the workpiece position is fixed during electroplating, increasing friction, and preventing the workpiece from shifting under the flow of electroplating solution or current impact. It is especially suitable for fixing high-precision or complex-shaped workpieces. The flattened clamp contact surface is more uniform, which can reduce the risk of uneven current density distribution and reduce the phenomenon of excessively thick or thin plating in some areas. The surface texture formed by roughening can disperse the current path and prevent the current from concentrating on a single contact point, thereby reducing defects such as plating pitting and burning.
[0030] Furthermore, the flattened clamping part 41 is made by flattening the front end of the dovetail clamp 4 and bending it 90°. Then, the end of the flattened clamping part 41 is processed into a dovetail shape by stamping and shearing to form a dovetail contact 42. The plastic part is elastically pressed by the cooperation of the clamping frame 3, the flattened clamping part 41 and the dovetail contact 42.
[0031] In use, by shifting the connecting synchronous frame 7 to the left, the connecting synchronous frame 7 causes the front end of the clamping frame 3 to shift to the left. The clamping frame 3 then causes the flattened clamping part 41 and the dovetail contact 42 to shift to the left and move out of the U-shaped frame 2. The plastic part is then hung above the horizontal support end 21, releasing the support and pushing on the connecting synchronous frame 7. The clamping frame 3 then returns to its original shape, and the front end of the clamping frame 3 shifts to the right, causing the flattened clamping part 41 and the dovetail contact 42 to push the left side of the plastic part, pressing the plastic part tightly against the left side of the vertical blocking end 22. This quickly completes the clamping and fixing of the plastic part. Then, electroplating is performed. After electroplating is completed, pushing the connecting synchronous frame 7 causes the clamping frame 3 to shift to the left, which quickly releases the clamping of the plastic part, and then the plastic part is removed.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
