Embodiment approach

[0031] The structure, use and features of the present invention will be described in a deeper, clear and detailed manner below in conjunction with the accompanying drawings and preferred embodiments.

[0032] First please refer to Figures 2 and 3, the present invention is a method for laser processing the surface of a mold, mainly in front of the laser group 2 is provided with a group of optical variable focal length lens group 3, using optical zoom movement to achieve the processing mold method, which includes the following steps:

[0033] (a) Calculate the curvature of the surface area of ​​the workpiece to be processed by a computer, so as to obtain the change parameter of the laser focal length;

[0034] (b) Utilize the adjustment of the variable focal length lens group to quickly change the laser focal length to remove the surface of the workpiece to be processed;

[0035] (c) By adjusting the laser power parameters, the thermal energy of the laser removes the material o...

Abstract

A method using laser to machine the surface of die features that a group of focus-variable lenses is arranged in the front of a group of laser devices for speeding up the movement of focused laser point, the curvature of the surface to be machined is calculated by computer for controlling the laser machining parameters, and the machining and polishing are included.

Description

technical field [0001] The invention relates to a method for processing the surface of a mold by laser, in particular to a method in which a set of optical variable focal length lens groups are arranged in front of the laser group, and the optical zoom is used to quickly adjust the focal length of the laser to facilitate processing the surface of the mold. Background technique [0002] Laser processing technology is currently divided into two types. One is carbon dioxide laser (referred to as CO2), which is generally used in the processing of non-metal molds. The other is the Jacques laser (YAG) which is suitable for the processing of metal molds. [0003] In the case of YAG laser (YAG), its control processing state depends on the basic parameters of laser power (%), laser frequency (kHz) and engraving speed (mm / s), and the conditions of laser processing are controlled by the above three parameters . [0004] And the existing mold surface is processed to make the mold surf...
