A paint scraping device for rectangular enameled wire ends

Abstract

A paint scraping device for the end of a rectangular enameled wire, including a shearing step. Before the shearing step, a paint scraping step is set up. The lead wire of the outlet wheel of the unwinding machine first enters the hydraulic press slitting edge mold of the paint scraping machine, and punches from both sides. Die-cutting to remove the paint on both sides of the lead, and then enter the cross-cutting mold of the paint scraper machine to punch the upper and lower surface paint; the length of the blade of the longitudinal and transverse cutting dies is the sum of the lengths of the two bare wire ends, The horizontal distance between the front and back of the blade is a fixed-length line length; then the lead wire enters the shearing step, and the shearing mechanism performs shearing from the midpoint of the bare wire segment of the lead wire; the two sides of the paint scraping step, punching on the upper and lower surfaces, and shearing The cut rhythm of the body is synchronized. The device is composed of a longitudinal cutting machine and a cross cutting machine. The longitudinal die knife and the transverse die knife are respectively fitted in the longitudinal cutting die and the cross cutting die. The two dies are provided with horizontal wire holes. The invention utilizes the wire-passing rhythm of a shearing machine to punch two-sided paint leather with bare wires, and the effect is good and the paint scraping is automated.

Description

technical field [0001] The invention relates to a production method of a motor stator, in particular to a paint scraping device for a rectangular enameled wire end. Background technique [0002] The stator enameled wire of automobile generator has a rectangular section. The production method of the stator enameled wire is to put the rectangular enameled coil on the unwinding machine and unwind the wire. Soldering steps for bare wire ends. [0003] The paint scraping process is to scrape off the paint on the two wire ends of the formed U-shaped wire, so that the wire ends are exposed and the two wires are welded. A kind of prior art is manual scraping, and work efficiency is lower; Another kind is that the fixed-length line that has cut length is clamped on milling machine, after milling the paint leather on both sides earlier with milling cutter, then rotate 90 degrees and mill the other two sides of paint leather. This method work efficiency improves a lot than manual ope...
