Title:
METAL MIDDLE FRAME MACHINING PROCESS
Document Type and Number:
WIPO Patent Application WO/2019/140764
Kind Code:
A1
Abstract:
Provided is a metal middle frame machining process, comprising the following steps: obtaining a sheet material and cutting the sheet material into a linear profile (10); carrying out fine-machining on the linear profile; bending the fine-machined linear profile (20a) so as to obtain a metal frame (30a) with an R angle; welding the metal frame; and putting the welded metal frame into a die-casting mold, and providing die-casting molten metal to obtain a middle plate (50a) which is die-casting formed and connected to the metal frame so as to form a metal middle frame. According to the metal middle frame machining process, the metal middle frame adopts a process of bending, welding and die-casting forming, so that material waste caused by a metal frame machining margin is decreased, and the proportion of raw material costs in total manufacture costs is reduced. Meanwhile, procedures of middle stamping, CNC machining and hot processing are decreased, and the machining time of the metal middle frame is shortened, so that the production efficiency of the whole metal middle frame is improved.
