Problems solved by technology
[0003] The metal middle frame is generally obtained by blank forging or sheet CNC cutting. The use of these two methods of raw materials is high, the waste of materials is large, and the production cost remains high.
For this reason, a metal middle frame is obtained by combining a multi-segment frame and a middle plate with less material consumption. However, the structure of the metal middle frame obtained in this way is poor in stability, and it is easy to shake when the antenna groove is processed at the joint of the frame. , the processing size is prone to deviation, and the yield rate of production and processing is low

Abstract
The invention relates to a metal middle frame and a metal middle frame processing method. The metal middle frame processing method comprises the following steps of acquiring a bending section bar, a linear section bar and a middle plate, wherein limiting grooves are formed in the end parts of the bending section bar and the linear section bar; oppositely installing the bending section bar and thelinear section bar end to end on the periphery of the middle plate and forming a metal side frame; acquiring a plurality of limiting buckles, and enabling the limiting buckles to slip along the limiting grooves so as to fix the butt-joint end parts of the bending section bar and the linear section bar adjacent to each other; carrying out groove milling processing in the direction from the butt-joint end parts to the limiting buckles so as to obtain a first-stage groove; and taking the limiting buckles out of the limiting grooves, carrying out injection molding processing on the first-stage groove, and carrying out surface treatment on the metal side frame so as to obtain the metal middle frame with an antenna groove. The metal middle frame processing method is easy to operate and high in stability, the elastic deformation is inhibited, the stability in processing the antenna groove is ensured, and the processed metal middle frame has high yield.
Description
technical field [0001] The invention relates to the technical field of smart devices, in particular to a metal middle frame and a processing method for the metal middle frame. Background technique [0002] With the continuous development of mobile terminal technology, the application of smart phones, handheld computers, smart watches and other electronic devices has become very common and has become an important part of people's work and life. The shell of electronic devices usually adopts a metal middle frame structure. The frame structure has the advantages of wear resistance and easy heat dissipation, and at the same time can make the product leave a high-end impression on the user. [0003] The metal middle frame is generally obtained by blank forging or sheet CNC cutting. The use of these two methods of raw materials is high, the waste of materials is large, and the production cost remains high. For this reason, a metal middle frame is obtained by combining a multi-seg...
