Embodiment Construction

[0013] A mold processing technology, the specific requirements of the technology are as follows:

[0014] 1) Firstly, the mold is drilled with EDM technology; the mold is drilled with EDM technology, and the positioning of the center hole is accurate and efficient.

[0015] 2) Then the metal wire passes through the small hole, and the size of the hole to be opened is set on the wire cutting machine computer, and the wire cutting machine is used to precisely open the hole; heavy oil is used for cooling and lubrication, and the mold is slightly damaged.

[0016] 3) Finally, the mold is manually repaired and polished to obtain the mold.

[0017] Using the invention to process the mold, the positioning of the center hole of the mold is accurate and efficient; the size is accurate and the deviation is small; the mold is slightly damaged and the service life is prolonged; the dependence on the experience of the operator is greatly reduced; misuse and scrapping.

Abstract

The invention discloses a mould machining process. Specific requirements of the process include adopting an electric spark quenching technology to drill a small hole in a mould, enabling a metal wire to penetrate the small hole, setting a dimension needed for hole forming on a wire cutting machine, adopting the wire cutting machine to accurately form a hole, performing manual mould mending and polishing and obtaining the mould. A wire cutting technology is utilized to replace a sand grinding process, positioning of a central hole is accurate and efficient, the dimension is accurate, deviation is small, mould yield rate is high, and mistaken operations and scrappage are reduced.

Description

technical field [0001] The invention relates to a transformer in electric power equipment, in particular to a mold processing technology for paper-wrapped winding wires and transposition wires of transformers. Background technique [0002] At present, the paper-wrapped winding wires and transposed wires for domestic transformers use molds to control the outer dimensions of the wires, and the demand for molds is relatively large; as transformers continue to be used in UHV fields, the requirements for the accuracy and smoothness of wire sizes are getting higher and higher. requirements are more stringent. [0003] At present, the sand grinding process is used to produce the mold, that is, first drill the mold alloy through the drill bit, pass the high-strength grinding wheel head through the small hole of the mold, start the motor to rotate the high-strength grinding wheel head, the small hole of the mold continues to expand, and use solder wire to pass through the small hole ...
