Description

Technical Field

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

[0002] Electroplating is a process that uses the principle of electrolysis to plate a layer of other metals or alloys onto the surface of certain metals. Through electrolysis, a metal film is attached to the surface of metal or other material parts to improve their service life. During electroplating, the electroplating solution needs to be preheated to a specified temperature to ensure the integrity of the electroplating effect.

[0003] For example, Chinese Patent CN209568167U (An Electroplating Preheating Device for the Surface Treatment Industry) includes a preheating tank and a support frame. A cylindrical preheating tank with an open top is fixedly connected to the upper surface of the support frame. In use, the workpiece is placed in the preheating tank using a hanger, and the electroplating solution in the preheating tank is heated by a quartz heating tube, thus preheating the workpiece and reducing the probability of peeling during electroplating, thereby improving the quality of electroplating. In use, the electroplating solution in the electroplating tank is filtered through a filter cover and then pumped back into the electroplating tank, giving the device the function of cleaning the electroplating solution. Furthermore, by rotating the filter cover, the external threaded ring is no longer connected to the internal thread of the mounting cylinder, allowing the filter cover to be disassembled independently, which facilitates cleaning and replacement of the filter cover and reduces the difficulty of using the device.

[0004] However, in existing electroplating processes, the preheating of the electroplating solution is mostly achieved by heating the solution through heating pipes installed at the bottom of the heating chamber. The heat is dissipated from bottom to top in a continuous diffusion manner, resulting in rapid heat loss from the top and uneven heat distribution between the top and bottom, which affects the electroplating effect. Therefore, this method does not meet the current requirements. To address this, we propose a preheating device for electroplating. Utility Model Content

[0005] The purpose of this invention is to provide a preheating device for electroplating, in order to solve the problem mentioned in the background art that in the existing electroplating process, the electroplating solution is preheated mostly by heating tubes installed at the bottom of the heating box. The heat is dissipated from bottom to top and in a continuous diffusion manner. The heat loss from the top is fast, which easily leads to uneven heat distribution between the top and bottom, thus affecting the electroplating effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a preheating device for electroplating, comprising: an electroplating tank, wherein a protective component is provided inside the electroplating tank, a heating space is formed between the outer periphery of the protective component and the inner wall of the electroplating tank, a plurality of quartz heating tubes are provided inside the heating space, and the plurality of quartz heating tubes surround the protective component, and a protective cover is provided at the upper end of the protective component.

[0007] Preferably, the protective component includes an electroplated protective frame, the outer surface of which is provided with a water-permeable opening that penetrates the electroplated protective frame.

[0008] Preferably, the protective component further includes limiting plates, and multiple limiting plates are provided. The multiple limiting plates are hot-melted and fixed to both sides of the top of the electroplated protective frame in equal quantities. Support frames are provided on the lower surface of the corners of the electroplated protective frame.

[0009] Preferably, both sides of the top of the electroplating box are provided with limit slots, and the limit plate is inserted along the limit slot.

[0010] Preferably, the upper surfaces of the front and rear ends of the protective cover are provided with fixing frames, and the fixing frames are L-shaped. One end of the fixing frame is provided with a fixing bolt. The front and rear surfaces of the electroplating box near the top are provided with bolt holes, and one end of the fixing bolt passes through the fixing frame and is threaded into the bolt hole.

[0011] Preferably, a controller is provided on the front surface of the electroplating tank near the bottom, and the output end of the controller is electrically connected to the input end of the quartz heating tube.

[0012] Preferably, the lower surface of the corner of the electroplating tank is provided with a support leg, and multiple support legs are provided. A drain outlet is provided on the side surface of the electroplating tank near the bottom, and a valve is provided at the upper end of the drain outlet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets up an electroplating protective frame inside the electroplating box. The quartz heating tube is installed inside the heating space formed by the outer perimeter of the electroplating protective frame and the inner wall of the electroplating box. The electroplating protective frame prevents the electroplated items from contacting the quartz heating tube after being placed inside the electroplating protective frame, thus preventing collision damage. Since multiple quartz heating tubes surround the electroplating protective frame, the temperature will concentrate in the middle when heating, reducing heat loss and improving the uniformity and stability of heating. This solves the problem that in the existing electroplating process, when preheating the electroplating solution, most of the heating is done by heating tubes installed at the bottom of the heating box. The heat is dissipated from bottom to top and in a continuous diffusion form. The heat loss at the top is fast, which easily leads to uneven heat distribution between the top and bottom, thus affecting the electroplating effect.

[0015] (2) By setting limit plates on both sides of the top of the electroplating protective frame and setting limit slots on both sides of the inner wall of the electroplating box, when placing the electroplating protective frame, the limit plates are inserted along the limit slots to limit the electroplating protective frame, avoid shaking and displacement, improve connection stability, ensure that the electroplating protective frame will not cause squeezing damage to the quartz heating tube, and improve safety.
