Example Embodiment

[0032] Example 1:

[0033] When hanging outside the reserved area, punch a hole of Φ3 at the highest point → hook up → pickling → water washing → drying → brush release agent → dip coating insulating protective material LTZ-230 → drying → dismantling → engraving → hooking → electric Chemical cutting → washing → drying → disassembly → peeling off insulating protective material → grinding → inspection.

[0034] The punching position of the electroformed nickel cladding sheet ensures the highest point, and pay attention not to be immersed in the bath during electrochemical cutting. Before dipping the insulating protective material, stick the parts to be cut with tape, then dipping the insulating protective material LTZ-230 five times with an interval of 15 minutes, and finally dry for 12 hours, with a dry film thickness of 0.25 mm; After the tape is lightly scratched, tear off the tape; use copper wire to hang the nickel-coated sheet for electric cutting in formula 1, and the cu...

Abstract

The invention belongs to the technical field of surface treatment, and relates to an electrochemistry cutting process method after forming of a paddle nickel-coated piece. The method comprises the process of dip-coating of an insulation protection material on the paddle nickel-coated piece and electrochemistry cutting. The thickness of a dry film in the dip-coated insulation protection material is0.22 to 0.35 mm, electrochemistry cutting liquid takes nickel sulfate or nickel aminosulfonate as main salt, and the problems that nickel chloride serves as the main salt, the cutting speed is slow,and after cut, a defect side phenomenon frequently happens can be solved. The electrochemistry cutting speed of nickel can be improved, the cutting edge of a part is uniform and free of defect side, the surface is free of corrosion leakage, and the insulation isolation material dip-coating process is simple and convenient to operate.

Description

technical field [0001] The invention belongs to the surface treatment technology, and relates to an electrochemical cutting process method after the blade is nickel-wrapped. Background technique [0002] The patent CN102995098 Electrochemical Cutting Process of Electroformed Nickel-clad Sheet mainly describes an electrochemical cutting bath formula for nickel-clad sheet. The main component of the electro-cutting bath solution is nickel chloride, and also includes nickel sulfate and boric acid. With nickel chloride as the main salt, its cutting speed is relatively slow and edge defects often occur after cutting. Contents of the invention [0003] The object of the present invention is to propose an electrochemical cutting method for nickel-clad blades, so as to improve the electric cutting speed and reduce edge defects. [0004] For solving this technical problem, technical scheme of the present invention is: [0005] A kind of electrochemical cutting method of paddle nic...
