Study On Electrochemical Machining Technology Of Self Guiding Curved Holes

By changing the physical state of the molding material, the mold can realize the processing of the article appearance. In electronics, automobiles, electric motors, electric appliances, instruments, meters, household electrical appliances and communication products,60% ~ 80% parts are to rely on mold molding. The mold curved cooling channel can effectively speed up the cooling rate of the mold, improve the quality of products and the production efficiency. The curved cooling channels are mostly composed of different curvature curved holes. Machining curved mold cooling channels is one of the main functions of the design of the device for machining the self guiding curved holes.Electrochemical machining is a kind of special processing methods based on the principle of anodic dissolution, which has the advantages of fast processing speed, good surface quality, wide processing range, no loss of cathode and so on, widely used in aerospace,aviation, weapons manufacturing and other fields. In this paper, the self guiding curved holes processing device is designed based on the theory of electrochemical machining.In this paper, a new method of curved hole machining was presented. Through the numerical control system to the control of the electrode feed mode effective, the shape of curved hole with ideal curvature was processed. Designed a complete set of device solutions.On this basis, the device was divided into three independent systems. For each system, refined the design of the device. Detailed designed of each part, and the key components, for example,electrode and traction control unit for electrode--moving control strip and other structures.With the theoretical knowledge, through theoretical calculation, simulation and other methods,material and structural was designed, model was selected. For the deficiencies, structure was improved and optimized and test validation was done. Finally, the device assembly drawing design was completed. Split the parts, machined the required non standard parts according to drawing and purchased the desired market available items. The assembly and debugging ofthe self guiding curved hole processing device was completed. According to the actual processing needs, surface machining quality and machining precision was selected as a measure. According to the method of orthogonal test, the corresponding test plan was worked out and curved hole machining process test was done. The corresponding electrolyte concentration, operating voltage, operating current, initial working gap and gap electrolysis hydraulic pressure and the optimum combination of the parameters were determined. Using the self guiding curved hole processing device, the ideal processing results were obtained.
