Abstract

The invention provides a manufacturing method of keys. According to the method, the operation surfaces of the manufactured keys are cambered keys, and the finished cost is reduced. A cold extrusion process is adopted, the operation surfaces of the designed keys are cambered shapes, a cambered module is correspondingly manufactured, the key blank according to cambered shapes of the operation surfaces of the designed keys can generate plastic deformation under the enough cold extrusion force, and a design requirement is achieved.

Description

A kind of key manufacturing method
Technical field: the invention belongs to lock technology field, relate to a kind of manufacture method of key.
Background technology: the pattern of present various keys has a lot, and its key working face is to adopt milling process processing mostly, is the shape of curved surface for the key working face,, can only adopt the CNC milling machine milling, processing cost is high.
Summary of the invention: the objective of the invention is to propose a kind of manufacture method of key, thereby can produce the key that the key working face is curved surface, cut down finished cost.Can realize purpose of the present invention by following technical proposals, adopt cold-extrusion technology, by designed key working face curve form, make the corresponding surface mould, under enough Cold Extrusion Forces, make key blank by designed key working face curve form generation plastic deformation, reach designing requirement.
The specific embodiment: according to the lockset desired tartar of unblanking, design corresponding key working curved surface, make the corresponding surface mould, adopt cold-extrusion technology, allow key blank by designed key working face curve form generation plastic deformation.

Claims (1)

1. a key manufacturing method, is characterized in that, adopts cold-extrusion technology, by designed key working face curve form, make the corresponding surface mould, under enough Cold Extrusion Forces, make key blank by designed key working face curve form generation plastic deformation, reach designing requirement.
