Abstract
Description
Technical Field
[0001] The invention relates to the technical field of process equipment, and in particular to an automatic exhaust and solution discharge device for electroplating deep blind hole parts. Background Art
[0002] The most important role of electroplating is to prevent corrosion. Different film layers are required according to different use conditions and performance requirements. The zinc-nickel alloy film layer of deep and large blind cylindrical parts has the following functions: first, it has excellent corrosion resistance; second, it has excellent mechanical properties, and does not change the yield strength, tensile strength and elongation of steel after plating, and has good plasticity; third, it has excellent brazing properties, and is easy to weld under various conditions, and there is no defect of long whiskers; fourth, the coating stress is small, which is suitable for electroplating on high-strength steel and can be used as a substitute for cadmium plating. However, deep blind hole parts are prone to air pockets without film layers when electroplating. If the closed end is at the bottom, the weight becomes heavier after entering the tank, and the solution is not easy to discharge from the tank when leaving the tank. If the closed end is at the top, there is air to hold the product, which is not easy to enter the tank and there will be large air pockets, especially for large parts. Auxiliary anodes are also required, and it is difficult to ensure the quality of the film layer, which affects the subsequent film layer effect. Summary of the invention
[0003] In order to solve the above technical problems, the present invention provides an automatic exhaust and solution discharge device for electroplating deep blind hole parts with simple structure and convenient operation.
[0004] The technical solution of the present invention for solving the above technical problems is: an automatic exhaust and solution drainage device for electroplating deep blind hole parts, including a tooling frame and an exhaust and drainage device, the exhaust and drainage device including a float valve, a threaded joint, a four-way joint, a straight joint and a 45° elbow, the float valve is connected to the lower port of the four-way joint through the threaded joint, the left port and the right port of the four-way joint are both connected to one end of a connecting steel pipe through a transversely arranged straight joint, the other end of the connecting steel pipe is connected to one end of a 45° elbow, the other ends of the two 45° elbows are respectively fixedly connected to a vertically arranged left steel pipe and a vertically arranged right steel pipe, the upper port of the four-way joint is fixedly connected to a vertically arranged middle steel pipe, and the left steel pipe, the right steel pipe and the middle steel pipe are all fixedly arranged on the tooling frame through an insulating plate.
[0005] The deep blind hole parts electroplating automatic exhaust and solution discharge device, the deep blind hole parts are sleeved on the left steel pipe and the right steel pipe.
[0006] In the above-mentioned automatic exhaust and solution discharge device for electroplating deep blind hole parts, the middle steel pipe is connected to the anode of the plating tank through an electric wire to serve as an auxiliary anode.
[0007] The beneficial effects of the present invention are as follows: the present invention utilizes the principle of controlling the inflow and outflow of tank liquid by a float valve. When the product starts to enter the tank, the tank liquid pushes the float valve to the upper end, and the solution cannot enter the exhaust and drainage device. The solution enters the deep blind hole parts and continuously compresses the air, and the air is discharged along the exhaust and drainage device. When the product exits the tank, the float valve falls, and the solution is discharged along the exhaust and drainage device. When it needs to be used as an auxiliary anode, the middle steel pipe is connected to the anode of the plating tank. The whole device has a simple structure and is easy to operate, which solves the problem of air pockets and difficult drainage in deep blind hole parts. BRIEF DESCRIPTION OF THE DRAWINGS
