Electroplating system for electrochrome plating treatment of rotary workpieces

Abstract

The invention provides an electroplating system for rotation workpiece chromate electroplating treatment. The electroplating system comprises a working groove, an electroplating device, a workpiece positioning device, a liquid storage groove, a washing liquid backflow liquid storage groove, a water tank and a waste gas treatment groove; the workpiece positioning device and the electroplating device are arranged on the working groove, the workpiece positioning device is used for fixing workpieces, and the electroplating device is used for electroplating the workpieces; a bottom liquid inlet anda side wall liquid outlet of the working groove communicate with a liquid outlet and a liquid inlet of the liquid storage groove through pipes correspondingly; an air exhaust opening of the working groove communicates with the waste gas treatment groove through a pipe; and a spraying washing opening of the working groove is connected with the water tank through a water inlet pump. The electroplating system is reasonable in structure, convenient to operate and simple in use; the electroplating device is arranged for improving the workpiece surface electroplating uniformity, the follow-up grinding working quantity is reduced, and meanwhile, energy consumption is saved; the waste gas treatment groove and the washing liquid backflow liquid storage groove are arranged, and therefore waste gasand waste liquid emission is reduced, and waste gas and waste liquid recovering and treatment and zero emission are achieved.

Description

technical field [0001] The invention relates to an electroplating system, in particular to an electroplating system for chrome-plating treatment of a workpiece of a rotary body. Background technique [0002] Chromium plating has excellent wear resistance and corrosion resistance. Although the EU ROHS Directive clearly stipulates that electrical and electronic equipment shall not contain hexavalent chromium since 2008, and the "China ROHS" plan matching the EU Directive has been implemented in China, but due to In the actual manufacturing of industrial products, low-cost technology that can replace chromium plating, especially hard chromium plating, is still extremely scarce. Therefore, the electrochrome plating process is still widely used in the manufacturing industry. For example, hard chromium plating is used in the steel cold rolling industry. Used for roughening and over-tolerance repair of rolls; piston rings, cylinder inner walls and piston rods of gas turbines use ha...

Problems solved by technology

In the published patent "Electroplating Device and Electroplating Method for Optimizing Temperature Field Distribution, ZL201410203254.3", it introduces the design method of achieving uniform coating on the workpiece surface by designing insoluble cylindrical anode, controlling electrolyte flow field, cathode and anode spacing, etc. , but there are no good solutions for how to ensure the stability of the relative position of the cathode and anode, solve the exhaust gas (electrolyte vapor) discharge, and automatically clean and reflow. In addition, the insoluble cylindrical anode with a fixed size is difficult to disassemble and adjust. Inflexibility and other disadvantages

The purpose of this patent invention is to provide an environmentally friendly compact electroplating device, which can avoid the influence of steam and waste liquid on the surrounding environment and construction personnel, and achieve the effect of environmental protection.
