Problems solved by technology

The metal middle frame structure includes a metal frame and a middle plate. Generally, the traditional metal middle frame adopts the method of integrally forming rough blanks, and then performs CNC machining on the rough blanks. CNC machining is more complicated, wastes more materials, and has low production efficiency. Conducive to the reduction of manufacturing cost
The improved process adopts the split forming method, that is, the metal frame is formed by forging and CNC processing, and then the metal frame and the middle plate are combined to form a metal middle frame structure. However, there are also defects of low efficiency and high cost.

Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided for the purpose of making the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly un...

Abstract

The invention relates to a metal middle frame machining process. The metal middle frame machining process comprises the following steps of: obtaining a plate and cutting the plate into a linear section; carrying out finish machining on the linear section; bending the linear section after the finish machining so as to obtain a metal frame with an R angle; welding the metal frame; putting the weldedmetal frame into a die-casting die, and providing die-casting molten metal to obtain a middle plate which is die-cast formed and connected with 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-cast forming, so that material waste caused by metal frame machining margin is decreased, and the proportion of raw material cost in total manufacture cost is reduced. Meanwhile, procedures of middle stamping, CNC machining and hot processing are decreased, the machining time ofthe metal middle frame is shortened and then the production efficiency of the whole metal middle frame is improved.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a metal middle frame processing technology. 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. The metal middle frame structure includes a metal frame and a middle plate. Generally, the traditional metal middle frame adopts the method of integrally forming rough blanks, and then performs CNC machining on the rough blanks. CNC machining is more complicated, wastes more materials, and has low production efficiency. ...
