Abstract
The present disclosure relates to a process of machining a metal middle frame, which includes the following steps of: obtaining a sheet material and cutting the sheet material into a linear profile; performing a finish machining to the linear profile; bending the linear profile after the finish machining, obtaining a metal border frame with an R angle; welding the metal border frame; and placing the metal border frame after the welding in a die-casting mold, providing a die-casting metal liquid, thereby obtaining a die-cast middle plate connected to the metal border frame, so as to form the metal middle frame.
Claims16
A method of machining a metal middle frame, the method comprising:
- obtaining a sheet material, and cutting the sheet material into a linear profile;
- performing a finish machining to the linear profile;
- bending the linear profile after finish machining, obtaining a metal border frame with an R angle;
- performing standard detections to the R angle, crack, and flatness of the metal border frame in such a manner that the R angle is consistent to the standard, a surface of the metal border frame has no crack, and a flatness of the metal border frame is less than 0.12;
- welding the metal border frame;
- and
- placing the metal border frame after the welding in a die-casting mold, providing a die-casting metal liquid, thereby obtaining a die-cast middle plate connected to the metal border frame, so as to form the metal middle frame.
A method of machining a metal middle frame, the method comprising:
- obtaining a sheet material, and cutting the sheet material into a linear profile;
- machining a dovetail groove on the linear profile;
- bending the linear profile to obtain a metal border frame with an R angle;
- jointing at least two metal border frames together by welding the metal border frames;
- and
- placing the metal border frame after the welding in a die-casting mold, providing a die-casting metal liquid to fill the dovetail groove, thereby obtaining a die-cast middle plate connected to the metal border frame, so as to form the metal middle frame.
A method of machining a metal middle frame, the method comprising:
- obtaining a sheet material, and cutting the sheet material into a linear profile;
- machining a patch groove on the linear profile;
- bending the linear profile to obtain a metal border frame with an R angle;
- providing an L-shaped metal patch and performing a finish machining to obtain a matched L-shaped metal patch;
- attaching the matched L-shaped metal patch in the patch groove in sequence and performing welding;
- jointing at least two metal border frames together by welding the metal border frames;
- and
- placing the metal border frame after the welding in a die-casting mold, providing a die-casting metal liquid to combine the metal patches, thereby obtaining a die-cast middle plate connected to the metal border frame, so as to form the metal middle frame.
