Floating self-centering enameled leather peeling method for wire end of enameled wire

Abstract

The invention relates to a floating self-centering enameled leather peeling method for a wire end of an enameled wire, is relative to the manufacturing technique of coils used in an electric motor, a transformer, a current transformer and the like, and mainly aims at the technological updating of the mechanical enameled leather peeling technology that is commonly used during the production process of the electric motor and an electric appliance coil. The floating self-centering enameled leather peeling method is characterized in that a three point centering principle is adopted, three equilong cutter arbors are led to rotate at a high speed, blunt cutters on the cutter arbors are led to be in flexible contact with an enameled leather part to be peeled on the wire under the centrifugal force, and the pressure of the flexible contact is floating and adjustable; and an enameled leather on the enameled wire can be scrubbed, ground and peeled off under flexible squeezing when the blunt cutters move in the axial direction. The floating self-centering enameled leather peeling method overcomes the principle and structural shortages in a conventional mechanical enameled leather peeling process method that enameled leather peeling cutter arbors are pushed through the rigidity of a conical end body so as to force the cutters to cut in the wire forcedly, has the advantages of high enameled leather scraping speed, good quality and high efficiency, is simple and convenient to operate and adjust, can satisfy enameled leather peeling process requirements of different wire diameters and different paint films after being adjusted for one time, and does not need to adjust, grind and replace the cutters, the cutter arbors and the conical end body frequently.

Description

technical field [0001] The invention relates to a floating self-centering enameled wire head peeling method for a lead wire. It is related to the coil manufacturing technology for motors, transformers, converters, etc. It is mainly aimed at the technical update of the mechanical paint stripping process commonly used in the production process of motors and electrical coils. The method of floating and self-centering paint peeling is adopted to achieve fast paint scraping and high efficiency. , Simple operation, convenient installation and debugging, low production cost and simple structure. Background technique [0002] The small diameter (0.5-3.5 mm) enameled wires used in the production of various coils such as motors, transformers, and converters need to be stripped (scraped) on the wire ends to ensure the integrity of the welding and crimping process. Smooth progress and normal conduction of current; at present, the enameled wire stripping process methods used are roughly...

Problems solved by technology

[0003] 1. Manual scraping and paint burning process is a relatively common manual process. This method is to remove the paint skin by manual scraping or burning the paint skin with a slight fire. The process looks simple, but it is actually very complicated; the paint layer is extremely difficult to completely scrape off. , and it is easy to produce oxide layer and pollutants, which will affect the soldering quality; moreover, it is easy to cause mechanical damage to the enameled wire copper, leaving stress scars, reducing the strength of the wire, and making the product quality fluctuate due to human factors

[0004] 2. The chemical peeling process has been greatly improved compared with the process of manual scraping and burning the paint, and the efficiency and quality have been improved; but there are still the following disadvantages: since the paint peeling is completed by chemical reaction, strict cleaning must be carried out procedures to remove residues and avoid disconnection caused by corrosion; moreover, the paint remover is harmful to the human body, so it must be prevented from intruding into the eyes and skin when using it, and chemical wastewater will also pollute the environment.

[0005] 3. The mechanical paint stripping process, at present, is more advanced to use a mechanical paint peeling machine to remove the paint, the most common is to use a tapered fork type peeling tool to peel the paint; this process method has high production efficiency and quality; but from the structure From the looks of it, there are still some deficiencies, such as poor stability in long-term work, and inconvenient adjustment of equipment and tools

[0006] In order to improve the efficiency and quality of paint stripping in coil production, during the research, we found that it is difficult to structurally improve the efficiency and quality of paint stripping with the existing tapered fork-type paint stripping tool; because, it The paint stripping tool relies on the rigid mechanical cone end to directly push off the paint stripping knife rod, forcing the sharp knife to cut into the paint and wire to perform hard scraping. In principle, it is difficult to guarantee that the wire substrate will not be damaged, because, The cone end body directly pushes the peeling knife rod, and the contact point has a large stress. The joint between the peeling knife rod and the cone end face is easy to wear, and it is difficult to ensure the synchronization of the peeling knife rod after a long working time; and, because it is a hard contact, it must be In order to avoid the accumulation and deformation of the cone end body, tool shaft, and tool errors, the paint stripping tool or the cone end body is often repaired or replaced to ensure centering and prevent the quality and efficiency of the paint stripping from being cut into the wire by one side of the tool.

And, because of the rigid contact, a different tool, shank or cone must be replaced every time the wire diameter is changed
